ABSTRACT="Eyeball ISPs today are under-utilizing an important asset: edge routers. We
present NetServ, a programmable node architecture aimed at turning edge
routers into distributed service hosting platforms. This allows ISPs to
allocate router resources to content publishers and application service
pro\-vi\-ders motivated to deploy content and services at the network edge.
This model provides important benefits over currently available solutions
like CDN. Content and services can be brought closer to end users by
dynamically installing and removing custom modules as needed throughout the
network. Unlike previous programmable router proposals which focused on
customizing features of a router, NetServ focuses on deploying content and
services. All our design decisions reflect this change in focus. We set
three main design goals: a wide-area deployment, a multi-user execution
environment, and a clear economic benefit. We built a prototype using
Linux, NSIS signaling, and the Java OSGi framework. We also implemented
four prototype applications: ActiveCDN provides publisher-specific content
distribution and processing; KeepAlive Responder and Media Relay reduce the
infrastructure needs of telephony providers; and Overload Control makes it
possible to deploy more flexible algorithms to handle excessive traffic.",

ABSTRACT="With increase in application complexity, the need for network faults
diagnosis for end-users has increased. However, existing failure diagnosis
techniques fail to assist the endusers in accessing the applications and
services. We present DYSWIS, an automatic network fault detection and
diagnosis system for end-users. The key idea is collaboration of end-users;
a node requests multiple nodes to diagnose a network fault in real time to
collect diverse information from different parts of the networks and infer
the cause of failure. DYSWIS leverages DHT network to search the
collaborating nodes with appropriate network properties required to
diagnose a failure. The framework allows dynamic updating of rules and
probes into a running system. Another key aspect is contribution of expert
knowledge (rules and probes) by application developers, vendors and network
administrators; thereby enabling crowdsourcing of diagnosis strategy for
growing set of applications. We have implemented the framework and the
software and tested them using our test bed and PlanetLab to show that
several complex commonly occurring failures can be detected and diagnosed
successfully using DYSWIS, while single-user probe with traditional tools
fails to pinpoint the cause of such failures. We validate that our base
modules and rules are sufficient to detect infrastructural failures causing
majority of application failures."

ABSTRACT="Traffic congestion in Malaysia is getting worse due to rapidly increasing
vehicle usage rates. It could seriously hinder the development of our
country if it's not managed correctly. These scenarios necessitate the
development of advance traffic management systems to increase the
performance of signalized intersection. Traffic signal timing management
(TSTM) system which comprise of genetic algorithm (GA) based optimization
and dynamic simulation prediction modules is proposed. With TSTM system,
network traffic flow can be improved with considerably less cost than other
infrastructural improvements. The proposed simulation module allows
modeling and analyzing of multi-lane multi-node traffic network with less
computing effort. This module has incorporated dynamic traffic flow,
vehicle routing, and vehicle interaction effects which describe the dynamic
traffic transition more realistically. The proposed GA based optimization
approach allows signal timing parameters such as offset, cycle time, green
split and phase sequence to be optimized with objective of minimum delay
and better traffic fluency. Nonetheless, the proposed TSTM system has the
flexibility to handle different kinds of traffic network by adjusting the
system parameters accordingly."

ABSTRACT="The use of multiple antennas at both the transmitter and receiver is well
motivated by the substantial performance gains that can be realized, both
in terms of an increase in achievable data rate and a decrease in error
rate. The achievable data rate is characterized by the mutual information
of the channel. In case of frequency selective multiple input multiple
output (MIMO) channels, expressions for mutual information are obtained by
using a block transmission model. In this paper, we consider a filterbank
equalization framework, which is an attractive alternative to the block
processing approach. We derive expressions for mutual information with the
minimum mean-squared error (MMSE) filterbank receiver, for both joint
detection and symbol-wise detection. It is shown that the filterbank
approach provides much better information rates than the block processing
approach. Simulation results are provided to validate our analysis."

IPv6 tunneling techniques, this paper evaluates the performance of two
recent IPv6 tunneling techniques: 6to4, and ISATAP. These protocols were
implemented on real test bed setup, on Microsoft Windows (MS Windows XP and
MS Windows Server 2003) and Linux operating systems. Five to six devices
were used to setup the whole test bed. Each protocol was then implemented
on the setup using specific configuration commands. UDP audio streaming,
video streaming and ICMP-ping traffic was run. Four different runs of
traffic were routed over the setup for each protocol. The average of the
data was taken to generate graphs and final results. The performance of
these tunneling techniques has been evaluated through certain parameters,
namely: throughput, end to end delay (E2ED), round trip time (RTT), and

minimizing transmit power under the constraint of preserving the minimum
distance of the initial signal constellation, but suffers from an increased

ABSTRACT="As technology is advancing, and the Internet becoming more vital, the need
for faster, cheaper, and simpler means of communication is becoming a must.
Worldwide Interoperability for Microwave Access (WiMAX), also known as IEEE
802.16, delivers high-speed access wirelessly, enabling fixed and mobile
broadband services over large coverage areas. The most challenging issue is
to measure and enhance the Quality of Service (QoS) of WiMAX networks. QoS
can be measured in terms of throughput, delay, and packet loss. The major
components of the QoS simulator include traffic generation, scheduling
algorithms, MAC and physical layers, resource allocation, and frame
construction. Several simulators were built in order to measure the WiMAX
QoS parameters. These simulators differ in the assumptions made and how
close they are able to model real life scenarios. The simulators have often
adequately captured most but not all of the major components required. In
this paper, a QoS simulator is introduced to implement all components of a
WiMAX communication system. The key contributions of the proposal are in
(i) the comprehensiveness of the simulator as it implements all the major
components of the WiMAX QoS, (ii) the real-life representation of the
traffic models, (iii) the building of the simulator from the grounds-up
without relying on off-the-shelf simulators, and (iv) the scalability of
the system as it can support a large number of users. The simulator follows
the path of data communication. It starts with the packet-switched input
traffic whose model is based on 3-levels: session, packet call, and
packets. Several scheduling algorithms are applied to these packets such as
Round-Robin, maximum sum rate, proportional fair, and guaranteed bit rate.
Subsequently, the MAC and PHY layers are implemented based on WiMAX
standards with the inclusion of adaptive modulation and coding based on the
user's specified Signal to Interference and Noise ratio (SINR). Frames are
constructed to allocate the required user resources. At the end, the
simulator outputs the levels of performance of the system by determining
QoS parameters including throughput, delay, packet loss, and number of
users served indicating the efficiency of resource allocation. Several
experiments are conducted to assess difference scenarios of scheduling
algorithms while varying one or more of the following: the input traffic
size, the size of the downlink subframe in a frame, the presence of
fragmentation, and the presence of adaptive modulation and coding. To
provide a high accuracy, the simulation considers several base stations and
a large number of users. It runs for an extended duration with a large
number of iterations from which statistics are derived to provide an
accurate representation of actual scenarios."

challenges in P2P VoD streaming are scalability and video quality. Both
require efficient utilization of the resources in P2P network. Inspired by
this finding, the paper addresses the problems of chunk scheduling and
bandwidth allocation in P2P VoD system to efficiently utilize the upload
bandwidth capacity of the peers. We first propose a queue based chunk
scheduling mechanism followed by a bandwidth distribution algorithm for
urgent downloading and prefetching. Our proposed mechanism allows the
maximum utilization of upload bandwidth by distributing the available
upload bandwidth among different queues. Experimental results show that
differentiated queuing is capable of achieving the optimal streaming rate."

ABSTRACT="In multihop networks such as mobile ad hoc networks selfish or misbehaving
nodes can degrade network performance. Reputation based models have been
developed to enforce cooperation and to discourage node misbehaviour. These
schemes detect and isolate selfish nodes and maintain network throughput by
enabling nodes to construct paths that only include good nodes. In order to
punish selfish nodes and restrict their services, selfish nodes are not
provided with packet forwarding services anymore by the good nodes in the
network; however they can still gain throughput or utility by interacting
directly with the destination nodes. The commonly adopted simulation
parameters used by the research community for the evaluation of reputation
based schemes in mobile environments usually produces high direct
interactions. These direct interactions result in noticeably higher
throughput and node utility for the network overall causing confusion:
these metrics are increased or decreased due to the direct interactions or
due to the reputation based scheme. We implemented the popular CONFIDANT
reputation-based scheme to confirm how much throughput is the result of
these direct interactions. Our simulation studies show that in the presence
of 20\% selfish nodes and in a continuous mobile environment, 59\% of the
evil throughput and 29\% of the good throughput was gained through direct
interactions among nodes. These direct interactions accordingly affect
delay and routing overhead in the network."

ABSTRACT="Falls are a major cause of hospitalization and injury related deaths among
the elderly population. The detrimental effects of falls, as well as the
negative impact on health services costs, have led to a great interest on
fall detection systems by the health-care industry. The most promising
approaches are those based on a wearable device that monitors the movements
of the patient, recognizes a fall and triggers an alarm. Unfortunately,
known techniques suffer from the problem of false alarms: some activities
of daily living are erroneously detected as falls, thus reducing the
confidence of caregivers in the system. This paper presents a novel
approach for improving the detection accuracy that is based on the idea of
identifying specific movement patterns into the acceleration data. By using
a single accelerometer, our system can recognize these patterns and use
them to distinguish activities of daily living from real falls; thus the
number of false alarms is reduced."

ABSTRACT="The main target of this paper is optimizing the slot-opening shift for
cogging torque reduction in BLDC motors. In a slot-opening shift method
there is no skew, therefore the known drawbacks of the skewing is
prevented. In the first part of the paper the slot-opening shift method for
a BLDC motor is discussed. In this case, it is desired to find a method for
cogging torque reduction without deteriorating the trapezoidal shape of
back- EMF. In the second part optimization of this method is discussed. In
this case, it's tried to optimize the amount of shifts in slot opening for
maximum reduction in cogging torque. Response surface Method (RSM) which is
a branch or Design of Experiments (DOE) is used as optimization Method. The
simulation result by finite element shows a considerable reduction in the
cogging torque of the optimized motor. Moreover the simulation verifies the
quality of back-EMF shape in each case."

ABSTRACT="In 2.4 GHz WLANs, channel assignment is critical issue due to minimum
availability of orthogonal channels (1, 6 and 11). WLANs which supports
Multiple Access Points (APs), either require maximum number of orthogonal
channels for individual links to reduce channel interference or some new
strategies adopt to improve the utilization of orthogonal channels. This
paper is deeming to find an efficient way to utilize the partially
overlapped channels of 2.4 GHz band as the orthogonal channels for WLAN
backhaul links, which has achieved high throughput due to minimum
interference between static links of backhaul with directional antennas. In
proposed work an equation is derived to find sets of orthogonal channels of
2.4 GHz band, directed graph applied on sets of orthogonal channels in
two-step approach (direct links and directional links) of each node. This
study has produced throughput results approximately double as compared to
traditional channel assignment with utilization of Partially Overlapped
Channels (POS). Future lines of this work would be to analyze proposed
channel assignment over backhaul using 5 GHz band to reduce adjacent
channel interference, same concept can be useful to increase the system
performance with MIMO and wireless mesh networks"

there is still a need to extend the concept so that a group of parties can
share a common key. This work suggests an algorithm that employs and
extends the mutual learning process to accommodate the much needed group
secure communication. Here, a recursive algorithm that depends on ordering
the parties in a binary tree structure is introduced. By applying this
algorithm, a group of $N$ parties is able to share a common key in a time
proportional to $\sup(\log\_2(N))$. The proposed algorithm implements two
binary tree approaches to achieve this objective, one uses a binary tree
with swapping, BEWS, while the other employs a binary tree with election,
BTWE."

infrastructure will not outsource their IT on the Cloud without strong

angle in this direction, which is about assessing the service delivery in a
Cloud's environment (it is also known as operational trust). More
specifically, we focus on analyzing the most important Clouds' properties,
which enable different interested parties to assess the operational trust
of a Cloud provider for delivering services. The assessment of operational
trust enables Cloud users, auditors, collaborating Cloud providers, and
others to compare multiple Cloud providers and decide on the best value for

caused by sending padding bits instead of useful data. The problem was
formulated as nonlinear integer programming model. Due to the complexity of
the problem, this paper presents first the formulation of the base model
for optimal DL bursts construction problem assuming the packet is
represented by one burst. Then, the formulation is expanded to allow the
representation of packets by several bursts. The results show an

ABSTRACT="In Wireless Sensor-Actor Networks (WSANs), sensors probe their surroundings
and send their data to more capable actor nodes in order to execute an
application task. The actors response is mostly collaborative and requires
them to coordinate their operation. Therefore, a strongly connected
inter-actor topology would be necessary at all time and tolerance of an
actor failure becomes a design requirement. Autonomous repositioning of
actor nodes has been deemed as an effective recovery strategy. This paper
presents a Least-Movement Topology Repair (Le-MoToR) algorithm. Le-MoToR is
a distributed scheme that relies on the local view of a node about the
network. To restore connectivity, Le-MoToR strives to relocate the least
number of nodes and reduce the traveled distance and message complexity.
Unlike contemporary schemes that maintain 1 or 2-hop neighbor lists,
Le-MoToR utilizes existing path discovery activities in the network in
order to know the structure of the topology and avoids imposing additional
pre-failure communication overhead. The simulation results validate the
effectiveness of Le-MoToR."

different types of contents. In this paper, we propose a technique for
evaluating the service quality of an institutional electronic library. Our
scheme is based on the service profiles of contents requested by the users
at the server side which is hosted at the library. Further, we propose
models to analyze the service quality of an electronic library. For
analyzing the service quality, we present two analytical models. The first
one is based on the number of days by which the item to be served by the
library is delayed and the penalty points per day for the duration for
which the item is delayed. The second model is based on the credits earned
by the library if the item is served in a timely fashion, and the
penalties, thereof, if the item is delayed. These models may help in
evaluating the service quality of an electronic library and taking the
corrective measures to improve it."

ABSTRACT="Mass metrology carried out in atmospheric pressure air is suitable for most
every critical application. However, mass metrology in vacuum is important
in several current research projects. Performing mass measurements in a
vacuum environment eliminates the need for air buoyancy corrections and
hence allows a more precise determination of true mass. In addition, the
major experiments for redefining the kilogram in terms of a physical
constant of nature, the watt balance and the Avogadro project, both operate
in vacuum. A kilogram that is redefined by these experiments will require
making the transfer from mass in vacuum to mass in air. Therefore,
understanding mass metrology in a vacuum environment is essential for doing
the research necessary to maintain world-class mass standards. In this
paper, we present an introduction to the techniques and apparatus needed
for vacuum mass metrology and discuss some of the work in this area being
done at NIST."

suppress the harmonic responses outside the band of interest. The presented
results of the proposed filter prove its UWB performance. It has a wide
upper stopband that extends above 20 GHz, and a compact size of 1.2 cm×1.8
cm. It also has a flat group delay with less than 0.1 ns peak-to-peak
variation across the passband revealing a distortionless performance when
operating in pulsed RF systems."

ABSTRACT="This paper reports the design of a planar antenna array for the use in an
ultra-wideband (UWB) microwave imaging system aimed for operation in the
band from 3.1 GHz to 10.6 GHz. The proposed planar array includes 6 × 2
UWB antenna elements in the form of compact (22 mm × 40 mm) corrugated
tapered slot antennas (TSAs). The antenna elements are designed to operate
in a coupling medium to improve the matching with the imaged object, and
thus to increase the dynamic range of the imaging system. They are covered
with a dielectric material to protect them from the adverse effects of the
coupling liquid. The designed array is tested in the presence of a
multilayer phantom representing an imaged object. The simulation
performance of the designed array shows good impedance match and low mutual
coupling of its elements and thus its readiness for use in UWB imaging
system."

ABSTRACT="Data classification has attracted considerable research attention in the
field of computational statistics and data mining due to its wide range of
applications. K Best Cluster Based Neighbour (KB-CB-N) is our novel
classification technique based on the integration of three different
similarity measures for cluster based classification. The basic principle
is to apply unsupervised learning on the instances of each class in the
dataset and then use the output as an input for the classification
algorithm to find the K best neighbours of clusters from the density,
gravity and distance perspectives. Clustering is applied as an initial step
within each class to find the inherent in-class grouping in the dataset.
Different data clustering techniques use different similarity measures.
Each measure has its own strength and weakness. Thus, combining the three
measures can benefit from the strength of each one and eliminate
encountered problems of using an individual measure. Extensive experimental
results using eight real datasets have evidenced that our new technique
typically shows improved or equivalent performance over other existing
state-of-the-art classification methods."

ABSTRACT="The Serving Call Session Control Function (S-CSCF) is the main node in the

an S-CSCF is performed by the Interrogating CSCF (I-CSCF) during the user
SIP agent registration. The I-CSCF assigns the S-CSCF based on the
capabilities required in the user profile. The 3GGP technical specification
does not require the I-CSCF to consider the S-CSCF load balancing. This
assignment scheme can lead to driving some of the S-CSCF nodes in the
network into overload while others are still under-utilized. In this paper
we present an S-CSCF assignment scheme that takes into consideration the
target S-CSCF current load. The proposed mechanism is shown to evenly

ABSTRACT="Installation of a system to monitor and measure sand production from an oil

two modules: a Sand Rate Calculation (SRC) module and a Distributed Data
Fusion (DDF) module. The framework is designed to collect data from oil
pipeline using acoustic sensors (SENACO AS100) in real time. A test bed was
established from ten acoustic sensors mounted on a closed loop pipeline.
Each acoustic sensor is attached to WSN node. Each node calculates its
local sand rate using SRC module. Every node sends its sand rate to the
neighbors. The DDF module at each nod is using its own local sand rate and
the neighbors' sand rate to fuse them in order to get the global sand rate.
The DDF is implemented using a Distributed Kalman Filter (DKF). The
proposed framework was successfully evaluated throughout the simulation and
experimental tests."

Electimize to be very efficient in solving NP-hard optimization problems.
The algorithm demonstrates higher capabilities in searching the solution

basic advantage of Electimize over other evolutionary algorithms (EAs) lies
in the evaluation process of the quality of the solution strings. Unlike
other EAs, Electimize evaluates the quality of every value in the solution
string independently. Recent research showed that Electimize is slow in
converging towards the optimal solution, if the size of problem is
increased. This paper presents a new mechanism for enhancing the

ABSTRACT="Productivity is an important economic factor which plays a key role in
economic growth. It is the foundation for economic prosperity, a
prerequisite for national development and an important indicator of
organizational competitiveness. There are several theoretical models that
measure the impact of technological changes on productivity growth.
However, there are few empirical studies that have tested the impact of
these changes on productivity in the metal industry. There is no published
work of research carried out in Bahrain in the stated sector. The main
objective of this paper is to investigate and evaluate the effects of
technological changes on the productivity of BALEXCO, the largest aluminum
extrusion company in the Kingdom of Bahrain and one of the largest in the
Arabian Gulf countries. In order to achieve this objective five steps were
undertaken. First, the factors that affect productivity of the aluminum
extrusion lines in BALEXCO were identified. Second, the specifications of
the technologies in the three extrusion lines 1, 2 and 3 - established in
1976, 1994 and 1996 respectively - were investigated, analyzed and compared
in order to evaluate the technological changes that occurred within the 20
years between 1976 and 1996. Third, a differentiation technology model
capable of evaluating and measuring the effects of technological changes on
the total productivity was developed. Fourth, the actual data required for
the measurement and for applying the model were collected over a period of
ten years. Finally, the model was applied to measure the total productivity
of the three lines, while the basic concept of productivity was used to
calculate the partial productivities. The results showed the extent of the
technological upgrading of the first, second and third lines in the
twenty-year period of study. The results of the productivity measurements
of the three lines showed that the total and partial productivities
improved dramatically as technologies were upgraded. For example, total
productivity of line 3 improved by 32.41\% compared to line 1; the partial
productivities of line 3 with regard to materials, labor, energy,
maintenance and repairs and consumables improved by 22.85\%, 117.33\% ,

ABSTRACT="Studies show that a significant number of problems in the construction
industry are due to lack, or delay, of communication and information. The
industry relies heavily on information and communication technology (ICT)
applications. However, it lags behind other industries in its management of
ICT. This research aims at developing a framework that improves the
management of ICT applications in terms of their evaluation, selection and
implementation. The framework builds on the Information Technology (IT)
Audit Tool introduced by the Construction Industry Council in the UK, and
on concepts of information economics, the Delphi Technique, the Analytic
Hierarchy Process (AHP), and project selection methods. The four main
framework procedures are: assess the current ICT situation; determine
required improvements; prioritize ICT applications by measuring their
financial and non-financial aspects; and the final selection of appropriate
ICT applications. The assessment of the current ICT situation is performed
using the IT Audit Tool. Criteria of financial and non-financial evaluation
are based on relevant literature and information economics concepts. Their
relative weights are assessed using the Delphi Technique and AHP to
prioritize ICT applications. Finally, project selection methodology is used
to select the most appropriate ICT applications. Each framework procedural
step is explained, particularly the financial and non-financial evaluation
of applications selection procedure. The framework was verified using a
case study, the outcomes of which led to the modification of the framework.
The main outcome of this paper is the introduction of a suggested framework

ABSTRACT="This paper deals with the design of sliding mode controllers (SMC) for a
vector-controlled of permanent magnet synchronous motor (PMSM). The
advantages of the sliding mode controller are disturbance rejection, strong
robustness and simple implementation. Speed and torque control of permanent
magnet synchronous motors are usually attained by the application of
position and speed sensors. However, speed and position sensors require the
additional mounting space, reduce the reliability in harsh environments and
increase the cost of motor. Many studies have been performed for the
elimination of speed and position sensors. Our proposed control strategy is
based on an accurate Extended Kalman Filter (EKF) observer which estimates
speed, position, rotor -fixed current and load torque. The investigations
show that the EKF is capable of tracking the actual rotor speed, position
and load torque provided that the elements of the covariance matrices are
properly selected. Moreover, the performance of the EKF is satisfactory
even in the presence of noise or when there are variations in permanent
magnet synchronous motor load."

ABSTRACT={In this paper we present the first biologically inspired framework for
indentifying communities in dynamic social networks. Community detection in
a social network is a complex problem when interactions among members
change over time. Existing community identification algorithms are limited
to evaluating a snapshot of a social network at a specific time. Our
algorithm evaluates social interactions as they occur over time. The user
can see the detected communities at any given time. We propose a relatively
simple, scalable, and novel artificial life-based algorithm named
{"}SFloscan{"}. This algorithm is based on the natural phenomena of bird
flocking. We model a social network as an artificial life where members
flock together in a virtual two-dimensional space to form communities. We
demonstrate empirically that our algorithm outperforms and overcomes the
limitations of the algorithms used for community detection. We analyze the
performance of SFloscan using datasets widely used in the real world.}

of speed estimation that operates on the principle of speed adaptive flux
and current observer has been proposed. An observer is basically an
estimator that uses a plant model and a feedback loop with measured stator
voltage and current. Simulation results show that the proposed direct field
oriented control with the proposed observer provides good performance
dynamic characteristics. The IM is fed by an indirect power electronics
converter. This indirect converter is controlled by a sliding mode
technique that enables minimization of harmonics introduced by the line
converter, as well as the control of the power factor and DC-link voltage.
We study the robustness of the overall system using simulation for
different operating modes and varied parameters."

provide an accurate navigation solution, however, in urban canyons and

provide a reliable navigation solution. Towards the search for a more
accurate and low-cost positioning solution, integrated navigation
algorithms are developed which utilize the measurements of low-cost motion
sensors such as accelerometers and gyroscopes, and integrate them with GPS
measurements to provide a reliable navigation solution. The goal of this
research paper is to narrow the idea-to-implementation gap by realizing the
navigation algorithm on a portable low-cost real-time embedded system. The
role of such system is to acquire and synchronize the measurements from
multiple sensors and then apply a navigation algorithm which integrates the

selection of the pole and slot numbers which results in negligible coupling
between phases. The preferred slot and pole number combinations eliminate
the effect of low order harmonics in the stator MMF and thereby the

identical machine dimensions, are designed with different slots per phase

modified winding function is presented. FEA is used to determine the flux
linkage vector due to permanent magnet. A simulation study is carried out
to compare the performance of the three designed machines when used in wind

ABSTRACT={Network delay is a crucial metric for evaluating the state of the network.
We present in this paper a structural analysis of network delay, based on
delay measurements of a backbone network. This delay analysis is performed
using a subspace method called Principal Component Analysis (PCA). The
analysis reveals that the delay time series can be decomposed into two
constituents: a smooth periodic trend and the impulsive sparse burst. We
call the former the {"}normal{"} component and the latter the
{"}abnormal{"} component. While this structural decomposition is appealing
and may be used to further infer other delay information of interest, we
find that using PCA in delay analysis has the same challenges as used in
traffic analysis. Particularly, it experiences performance degradation due
to the so called {"}perturbation phenomenon{"}.}

ABSTRACT="In contention-based wireless networks, packet collisions are considered the
main source of data loss. Retransmission of the lost packet is done several
times until an acknowledgment of successful reception (ACK) is received or
the maximum number of retries is reached. The retransmission delay is drawn
randomly from an interval, called the Backoff Interval. A good choice the
backoff interval reduces the number of collisions and, therefore, increases
the throughput and decreases the energy consumed in retransmissions. In
this paper, we propose a backoff scheme based on fuzzy logic. The new
scheme depends on locally measured data to estimate the backoff interval
which supports the distributed nature of the vehicular networks. We present
several versions of the Fuzzy Backoff scheme and compare them with other
known schemes: the binary exponential backoff (BEB), and an optimal scheme
which requires the knowledge of the total number of nodes in the network.
We used throughput, fairness, and energy consumption as performance
measures for evaluation. Results show an improvement of the fuzzy-based
schemes compared to the BEB, and approaching the optimal results."

lattice resolution is increased step by step to achieve a satisfactory
deformation of the source shape to exactly match the target boundaries. Our
point-based registration is based on least squares that measure the
Euclidean distance between source and target boundaries in addition to the
shape constrains. The minimization gives a closed form solution of the
lattice control points positions. Promising results will be demonstrated
for closed and open shapes and structures. The approach can also work for

ABSTRACT="In this paper, we propose an efficient relay selection scheme based on
geographical information for cluster based Distributed Space Time Block
Coding (DSTBC) cooperative systems. Also to realize Multi-hop transmission,
single cluster to cluster hops are concatenated where each
cluster-to-cluster scheme consists of a single source-destination pair and
a set of available relaying nodes to form the simplified cooperative
network. With the relay selection scheme, in each cluster-tocluster hop,
the source node selects an optimum relay among given relays to execute the
cooperative diversity transmission via performing DSTBC transmission
strategy. The presented relay selection scheme is designed for minimum
average end-to-end probability of error at the destination by utilizing
only nodes' geographical information as relay selection criteria. As such
geographical information is often available during network setup, the
proposed scheme can efficiently perform relay selection without complicated
procedures that carry out the optimum relay by channel estimations, and
thus it reduces the computational complexity and hence this simplicity
makes it appropriate for fast-varying environments. Simulation results
demonstrate the proposed relay selection scheme can efficiently improve the
performance of the network in comparison with the random relay selection in
terms of average end-to-end probability of error."

performance of an integrated transportation system, for transporting
multi-types analogue, digital and baseband signals over single mode fibre

ABSTRACT="The Job shop scheduling problem (JSSP) is one of the NP-Hard combinatorial
optimization problems. During the last four decades, many researches were
devoted on this problem. The goal in the problem is to minimize maximum
completion time of jobs, known as makespan. This paper addresses an
approach to evolve Cellular Learning Automata (CLA) to make it able to
solve the JSSP by minimizing the makespan. First, problem definition and
cellular learning automata are described briefly. Then the new algorithm
proposed. This approach is applied to several instances of a variety of
benchmarks and the experimental results show that it produces nearly
optimal solutions, compared with other approaches."

Hypertension is called the silent killer because it has no symptoms and can
cause serious disease if left untreated for a long time. Thus, an
intelligent and accurate diagnostic system is needed in order to threat the

ABSTRACT="Power-aware routing algorithms in Wireless Sensor Networks (WSNs) aim to
solve the key issue of prolonging the lifetime of resource-constrained
ad-hoc sensor nodes. Contemporary WSN routing algorithm designs have severe
limitations on their scalability; that is, large-scale deployments of WSNs
result in relatively shorter lifetimes, as compared to small-scale
deployments, due to rapid sink node isolation caused by the quick battery
exhaustion of nodes that are close to the sink. In this paper, we analyze
the scalability limitations of conventional routing algorithms and compare
them to those of our recently proposed Hybrid Multi-hop routiNg (HYMN). We
mathematically analyze HYMN and show the relationship between network size
and routing algorithm scalability. Additionally, through extensive
simulations, we show that HYMN scales considerably better in terms of
network connectivity."

ABSTRACT={Wavelet and Fourier transform are the common methods used in signal and
image compression. Wavelet transform (WT) are very powerful compared to
Fourier transform (FT) because its ability to describe any type of signals
both in time and frequency domain simultaneously while for FT, it describes
a signal from time domain to frequency domain. Because of that, the
performance of FT is outperformed by the impressive ability of WT for most
type of signals (stationary or non-stationary). In this paper, we will
discuss the use of Fast Fourier Transform (FFT) and Discrete Wavelet
Transform (DWT) for signal compression. We do the numerical experiment by
considering three types of signals and by applying FFT and DWT to decompose
those signals. For DWT, various wavelet filters such as Haar (2 filters)
and Daubechies (up to 10 filters) are used. Signal compression is done by
selecting the threshold value to cut-off the unnecessary coefficients where
we filtered out the high frequency component. Based on Mean Squared Error
(RMSE), Mean Squared Error (MSE) and Compression Ratio (CR), we found that
both methods are capable to compress the signal where Haar is the best for
{"}Block{"} signal, D8 gives best result for {"}Mishmash{"} signal and FFT
is the best for {"}Heavy Sine{"}. We also showed the plots of RMSE versus
level of compression where we can see clearly the trend of compression for
all wavelet filters. All the numerical results were done by using Matlab

process, IGCRGA is proposed in this work. Besides, IGCRGA using the
technique of global minima still resolves the problem associated with IGCN
(Information Gain Clustering Neighbor) which traps the algorithm in local
clustering centroids. Although this problem was alleviated by both IGCGA
(Information Gain Clustering through Genetic Algorithm) and IGCEGA
(Information Gain Clustering through Elitist Genetic Algorithm), IGCRGA
solves the problem even better because IGCRGA assumes the lowest Mean
Absolute Error (MAE), the evaluation matrix used in this work.
Experimentation of the various heuristics / techniques in RS used in
personalization for cold start problems was conducted and a comparison of
their respective MAE was performed. The various heuristics / techniques
explored include: Popularity, Entropy, IGCN, IGCGA, IGCEGA and IGCRGA. The
result showed that IGCRGA is associated with the lowest MAE, therefore,
best clustering, which in turn results into best recommendation."

ABSTRACT="One of the primary diagnostic and treatment evaluation tools for brain
interpretation has been magnetic resonance imaging (MRI). It has been a
widely-used method of high quality medical imaging, especially in brain
imaging where MR's soft tissue contrast and non invasiveness are clear
advantages. MR images can also be used to determine a normal and abnormal
types of brain. Moreover, the MRI characteristics will help the doctor to
avoid the human error in manual interpretation of medical content.
Computer-based classification has remained largely experimental work with
approaches, one of them is, Support vector machine (SVM). SVM is a pattern
recognition algorithm which learns to assign labels to objects through
examples. This research paper is an attempt to use SVM to automatically
classify brain MRI images under two categories, either normal or abnormal
brain which refers to brain tumor. The determination of normal and abnormal
brain image is based on symmetry which is exhibited in the axial and
coronal images. Using feature vector gained from the MRI images, SVM
classifiers are use to classify the images. The process consists of two
components which are training phase and a testing phase. Percentage of
accuracy on each parameter in SVM will give the idea to choose the best one
to be used in further works. Other than that, value of percentage will give
the first interpretation either the brain image has the possibility of
brain tumor or normal. After all, we are using LabView IMAQ as the software
in our experimental work. We believe with the easiness of this graphical
programming and the capabilities of SVM will give a very good result."

ABSTRACT="A robust automatic crack detection method for non-uniform colour
distributions on texture images is proposed. In this method a new image
segmentation technique is developed while the Hough transform is used for
feature extraction. Meanwhile, the detection is based on standard
discriminant analysis, featuring Wilk's  selection criteria. The methods
and procedures were tested on commercial biscuit crackers, resulting in the
specificity and sensitivity of more than 98\% and 88\%, respectively. Since
the algorithm is implemented in software, the system could be programmed to
inspect other manufactured products."

ABSTRACT="Many systems are provided to transfer the power between two grids, such as

HVDC is used to transfer the power between two grids of the same or

power transfer application between two grids as a variable frequency

a new link to transfer the power between two grids using a twin stator

ABSTRACT="Colour image segmentation has becoming more popular for computer vision due
to its important process in most medical analysis tasks. One of the main
tasks is the segmentation of white blood cell (WBC) where the WBC
composition reveals important diagnostic information of a patient. In this
paper, the combination between linear contrast technique and colour
segmentation based on HSI (Hue, Saturation, Intensity) colour space were
used in order to obtain a fully segmented abnormal WBC and nucleus of acute
leukaemia images. The unsupervised segmentation technique namely k-means
clustering algorithm is used to ease the segmentation process. By
implementing the proposed segmentation technique, the fully segmented WBC
which consists of cytoplasm and nucleus regions can be achieved by using
the combination of linear contrast technique and segmentation based on H
component image. Meanwhile, the fully segmented nucleus can be obtained by
applying the segmentation based on S component image. The combinations
between linear contrast technique and segmentation based on HSI colour
space have produced a better effect on improving the accuracy of WBC
segmentation with segmentation accuracies of 99.02\% and 99.05\% for
segmented WBC and nucleus, respectively."

ABSTRACT="The isolation of compounds 1 and 2, respectively from two unrelated plants
[a Pandanus (Pandanaceae) and a Myrmecodia (Rubiaceae)] is presented.
According to the Nuclear Magnetic Resonance (NMR) spectroscopy, both
biomolecules could be a triterpene. The NMR data from P. tectorius'
phytosterol was compared, where a mixture of stigmasterol:b-sitosterol
(2:1) was reported. However, the signals for an exo-methylene group
likewise in Pandanus' antitubercular tirucallane, did not appear in the
1H-NMR spectrum of 1 and 2 (500 MHz, δH 0.5 - 5.5 ppm, CDCl3).
Furthermore, the 13C-NMR spectroscopy (125 MHz, δC 10 - 141 ppm, CDCl3)
suggested 1 and 2 as a non-ketosteroid of possibly 29 carbon atoms. Both
equally could be an aglycon triterpenoid, due to the absence of 13C-NMR
signals at δC 60 - 110, which are carbons' signals, assigned for sugar
moieties. However, one 13C-NMR peak at δC 71.81 and 71.82 [C-3 (OH)] was
detected, respectively for 1 and 2. Therefore, the occurrence of a
hydroxylated stigmastane-like molecule was proposed. Instead, two sets of
-C=C- bonds (1: δC 140.76; 129.29 and 138.29; 121.70); (2: δC 140.78;
129.31 and 138.29; 121.70) were observed. From 2D NMR spectra, 1 was
recognised as stigmata-(5,22)-diene-3-ol or stigmasterol. Stigmasterol was
also reported from a Hydnophytum species, another epiphytic myrmecophytes
associated with Myrmecodia. Recrystallizations were performed to purify
crystal 2 (13.4 mg colorless needles; Rf = 0.2), which was also proposed as
a type-1 molecule. In short, stigmasterol was identified as the major
non-polar component from these two plant extracts."

ABSTRACT="In this paper, we present a Failure Prediction System (FPS) using a novel
algorithm that extracts frequent anomalous behaviors based on multi-scale
trend analysis of multiple network parameters. The proposed Correlation
Analysis Across Parameters algorithm (CAAP) utilizes multiple levels of
timescale analysis to reveal the frequent anomalous behaviors. The CAAP
philosophy is that failures usually do not occur because of change in a
single parameter behavior; instead, a set of interrelated parameters change
their behaviors jointly and lead to a particular failure. The proposed
algorithm requires an enhanced version of FABM algorithm which was
presented by the authors in a previous paper and was used to analyze each
parameter's behavior individually. Moreover, the new version, called FABMG
algorithm, has the same polynomial computational complexity of O(n2). The
CAAP utilizes the data mining techniques of association rules mining in
order to reveal the existed correlation relationships. Consequently, as
found in this work, this approach improves the quality of the FPS results
which was relying on individual parameter analysis only. One of the
strengths of CAAP is that it requires the FABMG output only, i.e. it does
not require rescanning the database in order to produce the correlation
results."

ABSTRACT="Synchronization is of paramount importance to exploit thread-level
parallelism on many-core CMPs. In these architectures, synchronization
mechanisms usually rely on shared variables to coordinate multithreaded
access to shared data structures thus avoiding data dependency conflicts.
Lock synchronization is known to be a key limitation to performance and
scalability. On the one hand, lock acquisition through busy waiting on
shared variables generates additional coherence activity which interferes
with applications. On the other hand, lock contention causes serialization
which results in performance degradation. This paper proposes and evaluates
GLocks, a hardware-supported implementation for highly-contended locks in
the context of many-core CMPs. GLocks use a token-based message-passing
protocol over a dedicated network built on state-of-the-art technology.
This approach skips the memory hierarchy to provide a non-intrusive,
extremely efficient and fair lock implementation with negligible impact on
energy consumption or die area. A comprehensive comparison against the most
efficient shared-memory-based lock implementation for a set of
microbenchmarks and real applications quantifies the goodness of GLocks.
Performance results show an average reduction of 42\% and 14\% in execution
time, an average reduction of 76\% and 23\% in network traffic, and also an
average reduction of 78\% and 28\% in energy-delay2 product (ED2P) metric
for the full CMP for the microbenchmarks and the real applications,
respectively. In light of our performance results, we can conclude that
GLocks satisfy our initial working hypothesis. GLocks minimize
cache-coherence network traffic due to lock synchronization which
translates into reduced power consumption and execution time."

losses associated with security incidents and the probability that they
occur, is a suitable decision criterion when considering different
information system architectures. Risk assessment is the widely accepted
process used to understand, quantify, and document the effects of
undesirable events on organizational objectives so that risk management,
continuity of operations planning, and contingency planning can be
performed. One technique, the Cyberspace Security Econometrics System
(CSES), is a methodology for estimating security costs to stakeholders as a
function of possible risk postures. In earlier works, we presented a
computational infrastructure that allows an analyst to estimate the
security of a system in terms of the loss that each stakeholder stands to
sustain as a result of security breakdowns. Additional work has applied
CSES to specific business cases. The current state-of-the-art of CSES
addresses independent events. In typical usage, analysts create matrices
that capture their expert opinion, and then use those matrices to quantify
costs to stakeholders. This expansion generalizes CSES to the common
real-world case where events may be dependent."

ABSTRACT="In the two-user Gaussian Strong Interference Channel (GSIC) with finite

constellations of the two users enlarges the Constellation Constrained (CC)
capacity region. In this paper, a metric for finding the approximate angle
of rotation (with negligibly small error) to maximally enlarge the CC
capacity for the two-user GSIC is presented. In the case of Gaussian input
alphabets with equal powers for both the users and the modulus of both the
cross-channel gains being equal to unity, it is known that the FDMA rate
curve touches the capacity curve of the GSIC. It is shown that, with
unequal powers for both the users also, when the modulus of one of the
cross-channel gains being equal to one and the modulus of the other
cross-channel gain being greater than or equal to one, the FDMA rate curve
touches the capacity curve of the GSIC. On the contrary, it is shown that,
under finite constellation inputs, with both the users using the same
constellation, the FDMA rate curve strictly lies within (never touches) the
enlarged CC capacity region throughout the strong-interference regime. This
means that using FDMA it is impossible to go close to the CC capacity. It
is well known that for the Gaussian input alphabets, the FDMA inner-bound,
at the optimum sum-rate point, is always better than the
simultaneous-decoding inner-bound throughout the weak-interference regime.
For a portion of the weak interference regime, it is shown that with
identical finite constellation inputs for both the users, the
simultaneous-decoding inner-bound, enlarged by relative rotation between
the constellations, is strictly better than the FDMA inner-bound."

means of automation that ca be used to build a three-level hierarical
control system intended for assuring the product quality. Sensors and
devices that monitor technological parameters and the state of equipment,
as well as other mechanisms and actuators, from the first, or lowest, level
of the proposed automatic control system.On the second, or middle, level we
have modern microprocessors that can be used to collect, process, and
analyze analog information form sensors and devices of the first level,
calculate control efforts and apply those in actuating mechanisms in
accordance with selected control criteria. Implementation of automatic work
stations for technological personnel requires the third level of automatic
control, which is based on modern personal computers, network applications
for PCs, and appropriate software support. The obtained theoretical results
were tested and proposed for implementation in a chemical metallurgical
line of refining and affinage, where higher ratios of extraction of useful

ABSTRACT="Strong attentions into low carbon transportation systems cause the growth
rate of plug-in hybrid electric vehicles (PHEVs) increases around the
world. PHEVs have the capability of grid connection. Therefore, if the
effects of these vehicles such as overloading in distribution network are
ignored, many problems would happen. Many assessments have been conducted
over understanding the effects of PHEVs, but any pattern for describing the
state of battery in different hours of day has not considered in most of
them. Also, when the aggregated stored energy in such technologies is going
to be represented in energy markets, awareness about the amount of
available energy in battery and the status of access to this energy is
needed. Thus, an appropriate pattern could support aggregators with useful
information in order to participate in electricity markets. In this paper,
a novel method has been proposed to model the status of stored energy in
battery for various hours of day. Using this method, aggregators would have
better estimation over their available energy to offer in electricity

ABSTRACT="In this paper, a direct torque control (DTC) of encoderless Synchronous
Reluctance Motor (SynRM) drives is proposed based on emotional controller
and space vector modulation. The proposed modern controller is called brain
emotional learning based intelligent controller (BELBIC). The utilization
of BELBIC is based on the emotion processing mechanism in brain, and is
essentially an action, which is based on sensory inputs and emotional cues.
This intelligent control is inspired by the limbic system of mammalian
brain. In this work, a BELBIC controller is designed for torque and flux
control in stator flux reference frame, respectively. The proposed
controller is able to reduce the torque, flux, current and speed pulsations
during steady-state behavior while the fast response and robustness merits
of the classic DTC are preserved. In addition, in order to achieve a
maximum torque per Ampere (MTPA) strategy at any operating condition, a
search algorithm changes the stator flux magnitude. The proposed controller
is successfully implemented in real-time through a PC-based three-phase,
0.5 Hp SynRM. The obtained results show superior proposed control
characteristics, especially very fast response, simple implementation and
robustness with respect to disturbances and parameter variations. So the
proposed encoderless MTPA emotional controller for SynRM drives with
minimized number of dependent parameters presents excellent promise for
industrial scale utilization."

(ICT) arena is no exception. The energy consumption in the ICT sector is
increasing at a rate that deems energy consumption a possible limitation to
the continuous fast growth of the future Internet. We address this
limitation in two ways. (1) We propose a service oriented energy efficient
Internet architecture. This architecture exploits the advantages of the
unified provisioning of optical network and IT resources provided by the
service plane architecture. It introduces an energy-aware analytical model
and algorithms that cooperatively optimise the selection and scheduling of
resources such that the overall power consumption by both the network and
IT resources is minimised. (2) We propose a new infrastructure scenario
which introduces integrated {"}OXC-IT{"} resource nodes in addition to the
separate IT resource sites at the network edge. This scenario is evaluated
against the typical scenario of network nodes and IT resource sites in
separate location. Our results show that through the service plane,
energy-aware algorithms provide significant energy savings of 13\% and the
proposed infrastructure model can provide savings of 57\%.}

transmission over a realistic wireless channel able to ensure the best

consider a Closed-Loop MIMO-OFDM scheme with different precoder designs. In
particular, the high flexibility of QoS precoder allows taking into account
the scalability of JPWL jointly with the instantaneous MIMO channel status.
This increases the visual quality of received images. The monitoring of the
quality is made by a reduced-reference metric (QIP) based on object's
saliency and interest point, both linked to human perception. It is
performed in association with a robust JPWL decoder to determine the

ABSTRACT="Previous research showed that customer demand in retail stores is
influenced by the availability, volume and location of the product
displayed. A decision-making process is proposed to integrate the ordering
quantities and the allocated shelf space to reach a global optimal
profitability. The store's inventory management system carries an overall
inventory that combines backroom and sales floor inventory. Leading
retailers introduce radio frequency identification (RFID) into their supply
chains for real-time monitoring, automatic product identification and
tracking. In this paper an integer non-linear programming model (INLP) is
developed to determine the optimum inventory replenishment and shelf space
that jointly maximize the retailer's profit under shelf space and backroom
storage constraints. The demand function for each item incorporates the
main effects of shelf space as well as the location effects. A clear
distinction between showroom and backroom inventories through real-time
inventory monitoring using RFID is being considered. The proposed model was
solved using LINGO® optimization package that uses an exact algorithm to
solve different instances of the problem till optimality. Finally, the INLP
model was implemented in a real world case study in a large retail outlet
providing a large variety of products. The proposed model had been
validated and had shown logical results when using the experimental data
collected from the market. The results of the proposed model showed the
optimum inventory replenishment and shelf space quantities that jointly

ABSTRACT="Renewable energy utilization to generate electricity has gained a special
attention in the last two decades. To minimize transmission losses these
energies are utilized through Distributed Generation (DG) system. Wind
energy is one of the most popular sources of DG. To utilize wind energy,
multi-phase Permanent Magnet Synchronous Generators (PMSGs) are the most
efficient mechanical energy to electrical energy converter apparatus. Under
normal operation, the instantaneous terminal power of this machine is
constant, and in the case of a multi-phase network, it can be connected to
the network through a suitable converter. However, in some rural places or
low power branches of networks, due to economic reasons, the available
network is of single-phase type. In such systems, the load instantaneous
power has a pulsating term in addition to the constant term, and the
converter must match the constant terminal power of the PMSG with this type
of output. In limited existing works, the pulsating instantaneous power of
single-phase loads has been dealt with using large storage devices such as
bulk capacitors or large inductors. However, this results in a more
expensive, bulkier and less reliable system. This paper, summarizes the
state of the art of the research in the area of utilizing and controlling
matrix convertors in feeding single phase loads from a PMSG, while
maintaining its shaft torque almost constant, to avoid the effect of
pulsating torque on the generators."

is idle listening, i.e., the cost of actively listening for potential

dynamic duty cycling technique which aims at optimizing the sleep interval
between consecutive wakeups. We considered dual low power listening (DLPL)
WSNs, in which the sender waits a probe signal from the receiver before
starting to transmit. Since each sender receives probe signals from several
nodes, the data are routed on multiple paths in a cluster-tree network
topology. In this context, we propose an optimization framework for
minimizing the energy waste of the most power hungry node of the network.
To this aims, we first derive an analytic model that predicts the nodes
energy consumption. Then, we use the model to derive an iterative algorithm
which achieves convergence to a fixed and provably optimum point without
employing any central controller. Simulation results via NS-2 simulator are

the network graph, the MP routine may not converge to a fixed point. To
this end, we introduce a reweighted MP (ReMP) algorithm that perturbs the
ordinary min-sum algorithm by suitably re-weighting messages. ReMP
distributes the computational effort of achieving an optimal RA among
nodes. Such feature makes ReMP particularly attractive in wireless networks
allowing the convergence to a fixed and provably optimum point without

ABSTRACT="We address the Primary User (PU) detection (spectrum sensing) problem,

perspective. Specifically, we employ recently-derived closed-form and exact
expressions for the distribution of the standard condition number (SCN) of
uncorrelated and semi-correlated random dual Wishart matrices of finite
sizes, to design Hypothesis-Testing algorithms to detect the presence of PU
signals. An inherent characteristic of the SCN/RMT-based approach, is that
no signal-to-noise ratio (SNR) estimation or any other information on the
PU signal is required. On top of this property, other attractive advantages
of the new techniques are: a) due to the accuracy of the finite SCN
distributions, superior performance is achieved under a finite number of
samples, compared to asymptotic RMT-based alternatives; b) since
expressions to model the SCN statistics both in the absence (H0) and
presence (H1) of PU signal are used, the statistics of the spectrum sensing
problem in question is completely characterized; c) as a consequence of a)
and b), accurate and simple analytical expressions for the receiver
operating characteristic (ROC) - both in terms of PD as a function of PF
and in terms of PA as a function of PM - are yielded. It is also shown that
the proposed finite RMT-based algorithms outperforms all similar

ABSTRACT="In this paper a sliding mode controller is proposed for a continuous
current mode buck converter. High proficiency and simplicity of
implementation are the most significant features of the proposed
controller. To fix the switching frequency of the converter, the sign
function which generates the discontinuous control law in sliding mode
controller, is replaced with a hysteresis relay whose cycle is calculated
respect to the acceptable output voltage ripple. The proposed controller is
analyzed and simulated for an 8kw, 150V to 100V buck converter with Matlab
(Simulink Toolbox). Simulation results show the high performance of the
proposed controller specifically the switching frequency which is fixed at
16 KHz."

ABSTRACT="Synchronous generator output is proportional to generator load angle but as
the parameter moved up the power system security is at stack. Hence,
generators are operated well below their steady state stability limit. This
raises demand for efficient and fast controllers. Artificial intelligence,
specifically Artificial Neural Network (ANN) is emerging very rapidly and
has become an efficient tool for researchers working in realm of operation
and control of power system. ANN requires quite considerable time to tune
weights but it is fast and accurate once tuned properly. In this paper,
model free estimation-based adaptive and nonlinear approach is proposed to
replace conventional controller compensated automatic voltage regulator.
Thus reduces complexity and risk involved in indirect adaptive online
trained neurocontrollers used to drive dynamical systems."

ABSTRACT={Solar-power can provide a much needed energy source for wireless sensor
networks, which are remotely deployed and limited by the short battery
lifetime. A challenge in solar-powered sensor network is that solar power
is highly dynamic and volatile: sun light intensity varies significantly
with time, with the location of the deployment, the weather conditions,
solar panel orientation, and obstacles and shading. Therefore, even if all
sensors are equipped with solar panels, individual sensors can receive
vastly different amount of solar power, and a significant portion of
sensors may not receive adequate solar power. This paper addresses such a
challenge and introduces a sensor data collection scheme called {"}Green
Diffusion{"} that automatically adapts sensors data dissemination behavior
to the solar power received by the sensors. Performance evaluation shows
our scheme significantly reduces sensor battery energy consumption and data
latency, even when just a fraction of the nodes receive adequate solar
power.}

ABSTRACT={After deployment of a wireless sensor network (WSN), its operational
lifetime depends on limited energy resources. Significant improvement in
WSN lifetime can be achieved by adding to WSNs spare nodes that are
initially asleep but are ready to be switched on when any primary node uses
up its energy. The proposed Ph.D. research will improve the Low-Energy
Adaptive Clustering Hierarchy (LEACH) protocol. LEACH maximizes WSN
lifetime via randomized rotation of cluster heads. However, LEACH allows
for inefficiencies due to redundant area coverage. We propose the LEACH-R
protocol—a modification of LEACH. Its development has three main goals.
First, from the subset of WSN nodes that provide redundant area coverage it
selects the optimal collection of spares w.r.t. maximizing WSN lifetime.
Second, it decides: (i) how long the spares should remain passive
({"}asleep{"}), and (ii) which spare(s) should be used as replacements for
primary nodes that used up their energy. Third , it estimates the lifetime
of WSN as determined by energy consumption by its sensor nodes in all node
states. This goal requires calculating lifetime for primary sensor nodes
and spares, calculating duty cycles for all types of nodes, and determining
lifetime of node batteries.}

ABSTRACT="Wireless Sensor Networks (WSNs) consist of a set of small devices with
limited energy resources, reduced processing capabilities and a radio
frequency communication unit with limited transmission power. In some
applications, wireless channels between nodes are prone to high noise and
interference, where Automatic Repeat Request (ARQ) techniques are
inefficient for the power loss in packets retransmissions. Error Correcting
Codes (ECC) can be used to reduce the number of retransmissions. The high
processing power and processing time of ECC powerfull decoders make it
unsuitable to be implemented in sensor nodes. Simple ECC techniques come
with high redundancy in the transmitted packets and low correction ability.
In this paper we present a powerful ECC technique for sensor networks based
on Parallel Concatenation Turbo Codes. The soft-decision iterative decoder
is implemented at the base station and a low power turbo encoder and error
correction circuit are implemented at the sensor nodes. This approach
enhances the reliability of the network communications, while being
energyand delay efficient. We also tested effect of increasing number of
communication hops and variant interleaver memory sizes."

ABSTRACT={The purpose of this paper is to experimentally determine the optimal
optical parameters for transmitting light through the human fingernail bed
in order to measure the change in blood volume that occurs when force is
exerted on the fingertip. This {"}fingernail sensing{"} technique, which is
a form of photoplethysmography, involves the placement of LEDs and
photodetectors on the fingernail surface. As forces are applied to the
fingertip, the blood perfusion in the fingernail bed is affected, resulting
in various red and white regions of coloration beneath the fingernail.
Thus, the transmittance of light across the fingernail bed changes as a
function of applied force, resulting in a change in voltage from the
photodetector circuit. Much research has previously been done to build and
calibrate black-box models that estimate fingertip force based on the
photodetector outputs. However, the effect of varying the wavelength and
optical path length has never been thoroughly investigated. Due to recent
advances in the manufacturing of fingernail sensors and the availability of
surface mount LEDs of certain wavelengths, we now perform a thorough
experimental characterization of the sensitivity of the transmittance to
wavelength and optical path length. Results show the sensitivity is
maximized when using green light (525 nm) and when the surface mount LED
and photodiode are placed as close together as possible. Using data from
the experiments, we also calibrate a physically-based model of the optical
transmittance, which can be used to optimize fingernail sensor design.}

guaranteeing non-functional QoS requirements to its already admitted users.
We model the broker using a continuous-time MDP and consider various

ABSTRACT="The paper proposes diagnostic technique for identifying rotor broken bar in
speed sensorless three-phase induction motor drive system. Experimental
data is collected for healthy and faulty motor with two rotor broken bar.
The collected data is first processed using Wavelet packet 1-D
transformation to extract the statistical information. The statistical
information thus obtained is used to train the Adaptive Neuro-Fuzzy
inference system (ANFIS) which is used as fault classifier. The stator
current space vector magnitude is used in conjunction with Wavelet
transform as the current signature is the most effective method of fault
diagnosis. The speed signal obtained from the observer system is directly
used in ANFIS. The proposed synergy of Wavelet packet and ANFIS provide
highly accurate and computationally efficient tool that can be used for
on-line fault diagnosis."

puncturing. Also, starting with an LDPC code base-family, we construct LDPC
code families with longer block length but decodable using the same

ABSTRACT="Anomaly detection in data streams is the problem of extracting
subsequences, which do not match an expected behavior. Its importance
originates from its applicability in many fields such as system health
monitoring, event detection in sensor networks, and detecting eco-system
disturbances, etc. In detecting anomalous subsequences from data streams,
the main challenge for the existing techniques is to determine the lengths
of the normal and anomalous subsequences and thus creating a robust model
for detecting the anomalous subsequences. In this paper, we propose an
incremental algorithm based on the dynamic time warping technique to detect
anomalous subsequences in data streams. The proposed algorithm works with
relaxed constrains regarding the lengths of normal and/or the anomalous
subsequences. That is the proposed algorithm is able to detect variable
length anomalous subsequences from among variable length normal sequences.
The proposed algorithm can extract variable length anomalies with linear
cost of time and memory."

psychology and social sciences whose exploitation allows artificial systems
to analyze the human being status and define the most suitable services
collection for achieving users' satisfaction. Our work meets AmI objectives
by using a formal method for representing human moods and introducing the
so-called cognitive agents whose inference capabilities enable the
emotional services distribution for enhancing users' comfort and
simplifying the human/systems interactions. The agents reasoning engine is
based on a novel extension of Fuzzy Cognitive Maps (FCMs) benefiting on the

ABSTRACT="From an industrial and technological point of view, fuzzy control theory
deals with the development of a particular system controller on a specific
hardware by means of an open or legacy programming language that is useful
to address, in a high-level fashion, the hardware constraints.
Independently from the complexity of the addressed application problem, the
development time may be very expensive if the designers want to exploit the
possibility to collect different controllers in terms of an active,
cooperative and heterogeneous virtual organization. In order to bridge this
gap, we introduce the Fuzzy Markup Language (FML), a novel specific-purpose
computer language that defines a detailed structure of fuzzy control
independent from its legacy representation. This choice allows systems'
designers to to express their ideas in fast and simple way and, as a
consequence, speeds up the whole development process of a given complex

ABSTRACT="The use of powerline communications has attracted the attention of
researchers increasingly, since the data transmission by means of media
designed for the electrical energy delivery proves to be convenient,
reducing the number of cables. These advantages are particularly appealing
in many fields, like the railway, naval and aeronautical ones.
Nevertheless, a high data rate cannot be guaranteed by this kind of systems
since some problems have to be solved. In particular, the presence of noise
makes the transmission difficult, degrading the quality of received signals
and prohibiting the full application of this technology to the field of
communications. In this paper a method to detect noisy events that occur in
a powerline communication system in a naval environment is proposed. To
this aim, a model of the powerline used to transmit wideband signals is
employed to simulate different possible noisy conditions. The channel is
analyzed in the presence of three classes of noise which characterize the
system. A supervised technique based on the use of principal component
analysis and a k-mean classifier is developed to automatically detect the
presence and classify the specific noise which occurs during the
transmission. Numerical simulations show that the proposed approach enables
to classify the occurring of noisy events reliably."

ABSTRACT="WiFi-enabled buses and stops may form the backbone of a metropolitan delay
tolerant network, that exploits nearby communications, temporary storage at
stops, and predictable bus mobility to deliver non-real time information.

This paper studies the problem of how to route data from its source to its
destination in order to maximize the delivery probability by a given
deadline. We assume to know the bus schedule, but we take into account that
randomness, due to road traffic conditions or passenger boarding and
alighting, affects bus mobility. In this sense, this paper is one of the
first to tackle quasi-deterministic mobility scenarios.

We propose a simple stochastic model for bus arrivals at stops, supported
by a study of real-life traces collected in a large urban network with 250
bus lines and about 7500 bus-stops. A succinct graph representation of this
model allows us to devise an optimal (under our model) single-copy routing
algorithm and then extend it to cases where several copies of the same data
are permitted. 

Through an extensive simulation study, we compare the optimal routing
algorithm with three other approaches: minimizing the expected traversal
time over our graph, maximizing the delivery probability over an infinite
time-horizon, and a recently-proposed heuristic based on bus frequencies.
We show that, in general, our optimal algorithm outperforms the three, but
it essentially reduces to either minimizing the expected traversal time
when transmissions are always successful, or maximizing the delivery
probability over an infinite time-horizon when transmissions fail
frequently. For reliable transmissions and reasonable values of deadlines,
the multi-copy extension requires only 10 copies to reach almost the
performance of costly flooding approaches."

ABSTRACT="In this paper the problem of dimensioning dynamic optical WDM networks
under multi-hour traffic and soft QoS constraints is studied. Unlike
previous works, traffic matrices are generated according to a lognormal
distribution, a more realistic model than the usual uniform approach.
Additionally, instead of requiring hard QoS constraints (e.g. blocking
probability under a given threshold 100\% of time), soft QoS constraints
that allow blocking to increase during some periods of time are considered.
In multi-hour traffic, such soft QoS constraints seem to be a more natural
way of dealing with customer SLAs. Results show that using lognormal
traffic matrices and soft QoS constraints leads to a decrease in the number
of wavelength requirements. In the studied cases, this decrease was about
10\%."

explicit feedback from each of these users for scheduling and allocation of

by each user and is known as the CQI (Channel Quality Information). This
CQI is used by the BS for link adaptation to the scheduled users. When Base
Stations change their precoders in the next scheduling epoch, interference
levels and therefore CQI estimates made previously may no longer be
accurate, leading to reduction in system throughput. In this paper, we
discuss the benefits of using unitary precoders to reduce this mismatch in
CQI and thus improve system performance."

ABSTRACT="A firewall is a packet filter that is placed at the entrance of a private
network. It examines each packet that is incoming into the private network
and decides, based on the specified rules in the firewall, whether to
accept the packet and allow it to proceed, or to discard the packet. It is
essential for a firewall to process packets fast - if a firewall is slow,
a heavy load can bring the connection down, so the system becomes
vulnerable to denial of service attacks. A standard optimization is to
remove all redundant rules from the firewall. Current redundancy removal
algorithms require worst-case O(n^d) space to optimize a firewall, where n
is the number of firewall rules and d the number of fields in a rule. In
this paper, we develop a new theoretical approach to the problem of
identifying the redundant rules in a firewall. This approach enables us to
develop a fast new algorithm for the complete detection and removal of
redundant rules from a given firewall. This new algorithm requires only
O(nd) space. Theoretically, it still has a worst-case O(n^d) time, but we
show by running the algorithm on a large test set (over half a million
firewalls) that in practice it terminates in seconds, and is at least one
order of magnitude faster than current algorithms. Further, we show how to
break the redundancy detection problem into independent subproblems using
the techniques of projection and division; these subproblems can be solved
in parallel, so our algorithm can naturally take advantage of parallel
hardware to achieve further speedup."

ABSTRACT="With HomePlug 1.0 and HPAV specifications, windowed OFDM is now the most

modulation, named OFDM/OQAM, could notably improve the capacity of these
networks. Imposing an orthogonality condition only to the real field, this
modulation offers a great flexibility in the design of the prototype filter
that shapes its symbols. Nevertheless, to take advantage of this degree of
freedom, a study needs to be conducted to decide which prototype filter is
the most adapted for PLC networks. The prototype filter length, its time
and frequency localization and its orthogonality or nearly-orthogonality
properties, represent some parameters that will determine the performance
of OFDM/OQAM in a particular context. So, this contribution shows the
achieved throughputs by OFDM/OQAM in the in-home PLC context, using
different prototype filters and following the HPAV specification. These
throughputs are also compared to the ones provided by the windowed OFDM

such as the H1N1 is of paramount importance for public health authorities.
Studies have shown that effective interventions can be taken to contain the
epidemics if early detection can be made. Traditional approach employed by
the Centers for Disease Control and Prevention (CDC) collects
influenza-like illness (ILI) activity data from ``sentinel'' medical
practices. Typically there is a 1-2 week delay between the time a patient
is diagnosed and the moment that data point becomes available in aggregate
ILI reports. In this paper we present the Social Network Enabled Flu Trends
(SNEFT) framework, which monitors messages posted on Twitter with a mention
of flu indicators to track and predict the emergence and spread of an
influenza epidemic in a population. Based on the data collected during 2009
and 2010, we find that the volume of flu related tweets is highly
correlated with the number of ILI cases reported by CDC. We further devise
auto-regression models to predict the ILI activity level in a population.
The models predict data collected and published by CDC, as the percentage
of visits to ``sentinel'' physicians attributable to ILI in successively
weeks. We test models with previous CDC data, with and without measures of
Twitter data, showing that Twitter data can substantially improve the
models prediction accuracy. Therefore, Twitter data provides real-time

turbine systems, shaft voltage turned into a drawback of the AC generators
as well as the AC motors in the modern AC drive applications. This voltage
is a resultant phenomena of interaction between PWM strategies of power
electronics converters and AC generator structure. Common mode voltage
generated by PWM inverters and the parasitic couplings of the machine
structure in high frequencies create a model for the system which leads to
an induced voltage on the shaft. This paper investigates a shaft voltage
remediation strategy for a doubly fed induction generator. A three-level
back-to-back AC-DC-AC converter has been used in this system. This analysis
is based on reduction of the maximum common mode voltage levels by removing
related switching vectors from a switching pattern. Applying this technique
leads to a 66 percent reduction of the common mode voltage of the rotor
side converter which plays the key role in shaft voltage generation of the
DFIG. The advantages of proposed method are: voltage balancing of DC link

ABSTRACT="This paper presents the application of a measurement procedure for
improving data acquisition for the characterization of soft magnetic
ferrites. The approach is based on a voltamperometric technique and is
aimed at better measure minor asymmetric cycles improving the quality and
resolution of measurement data. Physical and mathematical conditions
require the use of current and voltage signals with very different dynamic
range since the major loop has to be traced together to the minor cycles.
In such a way, the possibility to get the signal via two channels with
different configuration is analyzed and discussed. Preliminary results are
reported in the paper together to some preliminary concerns relevant to the
metrological characterization of the method. Further results and a more
detailed metrological characterization of the procedure will be presented
in the final version of the paper."

medium-voltage applications is demonstrated by operating the converter in
inversion and rectification modes. To show the true benefits of combined
pulse width and amplitude modulation as number of voltage levels the
converter can generate increases, modular multilevel converter with 16
cells per arm capable of generating 17 voltage levels per phase (35 voltage

ABSTRACT="Wavelength Routed Photonic (or all-optical) Networks (WRPNs) with an
intelligent control plane will play a key role in providing the proper
ground for future Internet applications. However, classic Routing and
Wavelength Assignment (RWA) solutions are inadequate to be adopted by
WRPNs. The main issues regard physical impairments and QoT, processing time
and setup delay, lightpath (LP) survivability and minimization of resource
allocation. In case of critical services provisioning, LPs must have tight
QoT guarantees, even in case of network instability and failures. This work
presents two new impairment-aware RWA (IA-RWA) algorithms, specifically
tailored for the provisioning of critical services. These algorithms
guarantee absolute bandwidth and Bit Error Rate (BER) for LPs, assuring
survivability in case of single network failures. A high parallelizable,
combined RWA engine minimizes resource utilization without increasing setup
time. The performance of the proposed algorithms are evaluated with respect
to a modified version of a previously proposed IA-RWA algorithm that takes
into account QoT and survivability."

ABSTRACT="While much of the Asian productivity in agriculture was attributed to the
widely acknowledged success of the Green Revolution in much of the region
the poor productivity and lack of dynamism of Africa 's agriculture could
be explained in part by the disarticulated system of agricultural system of
innovation (ASI). Clearly much effort has gone into agricultural research
efforts in Africa since the colonial period but then inventive activities
have not translated to innovative products by which countries in the region
could gain global competitiveness. 

This paper conceptualizes the challenge of poor performance of African
countries in the context of changing knowledge and capabilities driven in
large part by not just R\&D by market conditions in agriculture.
Agricultural development depends to a great extent on how successfully
knowledge of relevance to the local context is generated and applied.
Investments in knowledge—especially in the form of science and
technology—have featured prominently and consistently in most strategies
to promote sustainable and equitable agricultural development at the
national level (Oyelaran-Oyeyinka et al 2010, Adebowale, 2009). Although
many of these investments have been quite successful, the context for
agriculture is changing rapidly—sometimes radically—and the process of
knowledge generation and use, and agricultural innovation, has been
transformed as well. Agricultural biotechnology in its different domains
has been instrumental to these changes.

This paper argues for context-specific innovation capacity development in
agricultural biotechnology. It employs a theoretical framework of
innovation capacity and drawing on this illustrate with the cases of
Malaysian and Nigerian oil palm sectors and how through the development of
specific capabilities as well as through consistent and targeted
investment, Malaysia's investment in building a sustained framework turned
an agricultural commodity into a wealth creating global value chain."

ABSTRACT="Building innovation capacity to produce new varieties of drought-resistant
crops, high-yielding and disease-resistant varieties helped achieve
agricultural self-sufficiency in several parts of the world. This
policy-induced process was characterised by state-led, public-sector driven
research on varieties of rice and wheat, focus on technological
infrastructure that increased land productivity, physical infrastructure
that enhanced proximity to markets. While there was enormous success in
Asia, little transformation took place in Africa despite state efforts and
widespread agricultural and R\&D policies. This failure in part led to
changes to the ways policies are delivered; for instance, since the 1980s,
private sector organisations have taken over much of the task of providing
high yielding varieties for agricultural production worldwide. In other
words, did policy matter and does policy matter? If policies are necessary
are they sufficient to deliver on the promise of an African Green
Revolution?

This paper will examine key changes in the context of agricultural
development that call attention to the need to examine how innovation
policy underpins greater productivity in the agricultural sector. These
changes are: (i) markets, not just production, that increasingly drive
agricultural development; (ii) the production, trade and consumption
environment for agriculture and agricultural products; (iii) knowledge,
information and technology of relevance to agriculture; (iv) exponential
growth in information and communications technology (ICT),; and (v) the
knowledge structure of the agricultural sector. We will illustrate with
comparative perspectives of selected countries.

 

These factors have changed the face of agricultural development and
rendered it intricately linked to global economic trade and knowledge
capabilities of countries, but also focuses emphasis on the inability of
African countries on the failed past policies to address economic growth
and food security needs of the poor.

 The paper will argue that policies are necessary but not sufficient and in
doing so examine the role of factors required to foster biotechnology
sector development in Africa ."

ABSTRACT="The major goal of today's wireless communication research is to develop
systems with reliable, bandwidth efficient, free of Intersymbol

Division Multiplexing) is the key digital communication technology of the
current decade. In this paper, reduction of peak-to-average power ratio
(PAPR) and performance comparison of OFDM and wavelet based OFDM (WOFDM),
with and without Alamauti coding, is made with the help of different
wavelet types and levels. The performance differences with altered digital
modulation schemes are also investigated. In WOFDM, the conventional
Fourier-based carriers are replaced with orthonormal wavelets (Haar,
Daubechies, Coiflet and biorthogonal) and the performance in terms of bit
error rate over AWGN and multipath Rayleigh fading channels is examined.
The proposed WOFDM scheme comprises a symmetric structure transceiver with
a perfect reconstruction quadrature mirror filter (QMF) bank. Results show
that the WOFDM scheme is similar to OFDM in terms of BER, but with 25\%
better bandwidth efficiency and improved PAPR."

ABSTRACT="The development of any nation does not hinge on natural resources possessed
but rather on the stock of knowledge available and how such knowledge can
be applied, even to natural resources, to solve practical developmental
problems. In the world today, the essential contribution of knowledge to
economic competitiveness and social welfare is widely recognised. Knowledge
is a crucial tool for overcoming underdevelopment. Therefore, knowledge
generated (hard or soft) within our research system may only profit or
promote economic development if adequate policy measures and strategies are
formulated and implemented to transfer such knowledge effectively within
the National System of Innovation (NIS). While developed economies had
embraced and developed their technology transfer base long time ago, it was
a recent phenomenon in Nigeria and this call for requisite model, policy
and strategy to leapfrog the economy. The major objective of this paper is
to suggest appropriate policy strategy and design a functional model that
will facilitate effective technology transfer from our research
institutions to the industry. The paper uses secondary data obtained from
the review of literatures on global best practices in Technology Transfer
(TT) and data gathered from the activities of the National Office of
Technology Acquisition and Promotion (NOTAP) in Nigeria. The paper equally
looked critically at the recent initiative of government on the
establishment of Technology Transfer offices in some universities and
Research institutes in Nigeria of which is compared to global best
practices. Cross country analysis and comparison is used to achieve the
objective. The paper discovered that TT stimulate economic growth and
development, build technological capability and fast track industrial
development. It was also discovered that requisite policy measures and
strategies are not in place in Nigeria to drive TT and the only age-long
policy on TT has not been implemented let alone of revision. The
interaction between research institutions and industry is weak and in fact
no proper coordination of research project among the research institutions
as same project may be awarded to more than one institution within the
research system. Finally, there seems to be no succinct policy on
intellectual property to really drive innovation within the economy. In
conclusion, having learnt series of lessons on global best practices in
Technology Transfer around the world, it is therefore imperative for
Nigeria to join in the race of development through effective policy and
adequate reward system for researchers to actually promote technology
commercialisation and foster linkages and interaction among the elements of
NIS."

ABSTRACT="Preface: Power dissipation has become one of the critical concerns in VLSI
circuits. Solution: Hence, the trend has been to search for techniques to
reduce the power dissipation, low power operation, and designing for energy
recovering and recycling. Adiabatic circuitry presents a promising
alternative to this approach. The main idea behind adiabatic design is to
transfer charge between circuit capacitors and a time-varying power-clock
node. This scheme enables the charge transfers to occur in a controlled
manner, limiting the currents and thus the dissipation across the active
devices. Thus, adiabatic circuitry can potentially achieve sub-CV2 energy
dissipation per cycle. This paper represents a Quasi- Adiabatic logic
designed using Latched Pass Transistor Logic LPAL topology, which are
generally used for low power operations. Basic standard cells (And, Or,
Inverter, Active low Buffer, D- Flip Flop) are developed using full custom
IC design flow, and then followed by cell Characterizing and creating a
Standard Cell Library. We made an effort to analyze the enhancement in the
power performance using above cell library created by implementing a simple
digital logic, modeled using HDL and then Synthesizing it using the
developed Standard cell library and with the Encounter design flow."

ABSTRACT="National development has for a long time been linked with the ability of a
country to deploy science and technology in solving their problems.
Biotechnology, a product of science and technology is being applied to
develop new and higher quality food and fibre, crops with greater stress
tolerance, and new uses for agricultural commodities. A growing number of
governments in developing countries are investing in infrastructure and
human resources to support national biotechnology programs as well as in
the adoption of policies to facilitate biotechnology research and
development in both public and private sectors. About a decade ago, the
Nigerian government signed and ratified the Cartagena Protocol on
bio-safety as a mark of interest in biotechnology; but not until very
recently was Nigeria's interest re-activated. This paper aimed to review
and synthesize the application of agricultural biotechnology to national
development, legislation in biotechnology, research and development (R\&D)
management, incorporating R\&D planning, programming and budgeting among
others and present some recommendations for Nigeria from the operating best
practices in agricultural biotechnology policies of selected national
economies. The countries reviewed were selected based on their capability
or development of biotechnology: the USA (where research and development
policies have been more favourable to biotechnology, transparency is
greater and confidence in biotechnology is fostered), UK and Germany
(member Europe's largest economies where biotechnology has been the subject
of political and public controversy), China, Malaysia, Brazil and India
(countries where huge investments have been made), South Africa (a
promising African country) and Nigeria (Africa's most populous nation
famously known as a major food exporter but now is a food deficit country)
and others. So far the lessons learnt have been the introduction of
Nigeria's Biosafety bill to the national assembly for consideration and
passage into law as well as the approval of two new applications for the
field testing of transgenic cow pea and cassava varieties by the committee
on Biosafety. The gaps in the lessons are highlighted in the
recommendations. The review concludes with recommendations that the
Nigerian government should increase expenditure on R\&D and relevant
infrastructure with a guided policy, demonstrate commitment to the training
of personnel for technology capability, foster technology transfer with the
establishment of offices for that purpose in all government research
institutes (GRI) and higher institutions, and fortification of intellectual
property rights."

ABSTRACT="Nowadays, high detection complexity is known to be one of the major
challenges in MIMO communications based on spatial multiplexing. Tuple
search (TS) sphere detection was recently introduced, demonstrating to
represent a promising approach in this context. It provides significant
complexity reduction in comparison to conventional algorithms, providing in
addition BER performance close to full max-log-APP detection. Due to the
increasing multiplicity of communication standards as well as variety of
mobile applications demanded by the users, tackling the lack of flexibility
of common receiver realizations has become an additional key challenge in
MIMO detection. The aim of this work is to demonstrate the benefit provided
by the tuple search strategy is still present in a wide range of possible
transmission schemes. For this purpose, a novel efficiency indicator is
introduced, based on which an exhaustive analysis is performed. The
existing tuple search detector has been adapted to deal with different
constellation orders and transmit/receive antenna configurations. In
addition, the applied MMSE strategy has been modified to support
undetermined systems. The obtained results show the superiority of the
proposed sphere detector under different transmission conditions, thus
demonstrating its efficiency and flexibility."

ABSTRACT={The solar thermal energy resource situation in Nigeria including the
estimated potential and available amount of the resource, are presented in
this paper. The status of the database is discussed, indicating its degree
of adequacy and an identification of the gaps. The National Energy Policy
Document states that {"}Nigeria lies within a high sunshine belt and,
within the country; solar radiation is fairly well distributed. The annual
average of total solar radiation is varies from about 12.6 MJ/m2-day (3.5
kWh/ m2-day) in the coastal latitudes to about 25.2 MJ/ m2-day (7.0 kWh/
m2-day) in the far north.{"} Assuming an arithmetic average of 18.9 MJ/
m2-day (5.3 kWh/ m2-day), Nigeria therefore has an estimated 17,459,215.2
million MJ/day (17.439 TJ/day) of solar energy falling on its 923,768 km2
land area. Energy is one commodity on which the provision of goods and
services depend. Its availability and consumption rate is an economic index
to measure the development of any community. In Nigeria, there is a
limitation to power supply from the National grid which has adversely
affected the economic and social development of the populace. This really
necessitates the need for decentralized power source as a viable
alternative to which solarthermal energy readily fits in.}

ABSTRACT={Long Term Evolution (LTE) is an emerging 4G wireless access technology.
Multiple-Input Multiple-Output (MIMO) systems which involve the use of more
than one antenna at the transmitter and receiver are a primary enabler of
the high data rate sought to be achieved by LTE.
Closed-Loop-Spatial-Multiplexing and Open-Loop-Spatial-Multiplexing are the
two primary MIMO Transmission Modes used in the LTE downlink. As per the
LTE standards, an LTE Base Station (eNodeB) is expected to select and
switch transmission characteristics of these MIMO modes based on channel
quality feedbacks: Channel Quality Indicator (CQI), Precoding Matrix
Indicator (PMI) and Rank Indicator (RI) reported by the mobile. In this
paper, we show analytically as well as through simulations, that is it
perilous to make MIMO transmission mode selection at the eNodeB based
solely on mobile feedback. We show that an eNodeB which selects MIMO
transmission modes based solely on mobile feedback can suffer from
significant reduction in throughput. We then describe an algorithm at the
eNodeB that can prevent such throughput reduction. The algorithm works by
enabling the eNodeB to override the mobile's channel feedback in certain
situations and make a better choice of transmission mode. We provide
simulation data to show that such an algorithm can improve the downlink
throughput by 110\% in some cases and by 25-50\% on an average. We also
show that an eNodeB equipped with this algorithm is able to match the
benchmarked {"}best case{"} downlink throughput for a wide range of signal
quality and channel models. LTE Transmission Mode selection algorithms
described in literature involve the estimation of additional channel
information such as mobile speed, channel diversity etc along with the
mobile's channel feedback in order to select the appropriate Transmission
Mode. The algorithm proposed in this paper is computationally much simpler
in that it reuses existing information at the eNodeB and does not involve
estimation of any of these additional channel parameters. It is also at par
or better in performance. This algorithm has been implemented in the
Motorola LTE product. It won the gold award for the best proposal out of
Motorola India.}

ABSTRACT="With the ever increasing growth of cloud computing and the resulting
outsourcing of data, concerns of data integrity, security, and privacy are
also on the rise. Among these, evidence of data integrity, i.e., being
tamper-evident and current, seem to be of immediate concern. While several
integrity techniques currently exist, most result in significant overhead
at the database owner site. For clients with large databases, these are not
viable solutions. In this paper, we propose a computationally efficient
alternative---database integrity with Bloom filters. We focus both on the
tamper-evidence and freshness properties of the database as well as
completeness of query results. We propose two schemes for integrity
enforcement---first using aggregates signatures and second using
authenticated data structures. We provide detailed analysis and
experimental results to prove their efficiency and correctness. The results
are compared with the traditional security hash functions such as SHA-1 and
are shown to be computationally efficient. We have also implemented the
schemes on multiprocessor systems which show further reduction in the
execution time. Our results clearly demonstrate the feasibility and
efficacy of employing Bloom filters to enforce integrity for outsourced
databases in cloud environments."

ABSTRACT="Compressing web traffic using standard GZIP is becoming both popular and
challenging due to the huge increase in wireless web devices, where
bandwidth is limited. Security and other content based networking devices
are required to decompress the traffic of tens of thousands concurrent
connections in order to inspect the content for different signatures. The
major limiting factor in this process is the high memory requirements of
32KB per connection that leads to hundreds of megabytes to gigabytes of
main memory consumption. This requirement inhibits and prevents most
devices from looking at and treating compressed traffic, which in turn
either limits traffic compression or introduces security holes and other
dysfunctionalities. In this paper we introduce new algorithms and
techniques that drastically reduce this space requirement by over 80\%,
with only a slight increase in the time overhead, thus making realtime
compressed traffic inspection a viable option for network devices."

introducing a new Markovian game theoretical solution. Despite the
previously reported works, in the proposed model, simultaneously
transmitted packets on a multiple-access channel are not always discarded.
In this article, the possibility of capturing one of these packets is
considered. Both cases of cooperative and non-cooperative stochastic game
solutions are investigated and compared. The main objective is to maximize
the system throughput with minimum transmission delay and power consumption
cost. Effect of different packet error rates due to possible collision
occurrence is considered in the game definition that improves system
performance further. Performance of the proposed non-cooperative game model
asymptotically approaches the cooperative case, however the non-cooperative
game model adds less signaling load to the system, therefore it is more
likely to be used in practical applications."

transmission durations for the secondary users becomes crucial in order to
maximize the secondary throughput while protecting the primary users from
interference and service disruption. In this paper an adaptive sensing and
transmission scheme for cognitive radios is proposed. We consider a channel
allocated to a primary user which operates in an unslotted manner switching
activity at random times. A secondary transmitter adapts its sensing and
transmission durations according to its belief regarding the primary user
state of activity. The objective is to maximize a secondary utility
function. This function has a penalty term for collisions with primary
transmission. It accounts for the reliabilitythroughput tradeoff by
explicitly incorporating the impact of sensing duration on secondary
throughput and primary activity detection reliability. It also accounts for
throughput reduction that results from data overhead. Numerical simulations
of the system performance demonstrate the effectiveness of adaptive sensing
and transmission scheme over non-adaptive approach in increasing the
secondary user utility."

ABSTRACT="Femtocell is an emerging technology that promises increased network
capacity and enhanced indoor coverage at a low capital and operational
cost. However, macrocell network performance depreciates when macrocell
users (mUEs) are located indoors with femtocell base stations (FBSs), and
these users are not allowed access to the FBSs (closed access). This is a
critical issue that needs to be addressed in order to successfully deploy
femtocell tier over existing macrocell networks. This paper proposes a
macrocell proportional fair-based batch resource allocation strategy that
enables FBS to be aware of macrocell resource usage schedule. In this
context, batch means multiple time-slots. The knowledge of macrocell
resource usage schedule enables the FBS to effectively mitigate
interference caused to mUEs in its neighborhood. We show by simulation
results that our proposed cross-layer interference coordination approach
significantly increases the total macrocell throughput through interference
reduction."

ABSTRACT="Recent analysis depicts that mobile data traffic is increasing with almost
exponential growth. Major part of this data traffic is generating from
indoors, the reason behind such increasing growth is the types of
applications that are being used, the operators business model and the
introduction of sophisticated devices. This huge growth not only requires
high asset for increased network capacity but also degrades the overall
capacity of the macro network. This paper provides a careful analysis of
throughput computed for LTE network and shows how degraded capacity affects
the aggregated throughput of the macro network. The paper also proposes two
possible emerging solutions, WiFi and Femtocell. By utilizing these
technologies how indoor traffic has to be offloaded from outdoor base
station to increase the performance of the whole network."

itself uses an improved LCR based Doppler shift estimation algorithm by
using only inherent information which is available in common receivers

Doppler shift at base station in cellular networks helps base stations in
channel estimation, which improves jamming detection performance,
effectively. The performance of the proposed algorithm in a TETRA network

performs better than randomly selecting pairs for comparison or selecting

advantage to this principled approach is that it appropriately adapts to a

ABSTRACT="This paper considers the problem of designing a multi-commodity network
with single facility type subject to the requirement that under failure of
any single edge, the network should permit a feasible routing of all
traffic. We study the polyhedral structure of the problem by considering
the multi-graph obtained by shrinking the nodes, but not the edges, in a
k-partition of the original graph. A key theorem is proved according to
which a facet of the k-node problem defined on the multi-graph resulting
from a k-partition is also facet-defining for the larger problem under a
mild condition. Using this theorem, we develop two classes of 3-partition
inequalities, and a large number of inequality classes based on
4-partitions. Computational results show that addition of 3- and
4-partition inequalities produces root-node bounds ranging from 97\% to
99.5\% of optimal solution in most instances. Using this approach, problems
of 20 nodes, 50 edges and 110 traffic pairs can be solved optimally within
a few minutes of computer time."

ABSTRACT="We give upper bounds that achieve new points in the three way trade-off
between space, stretch and query time for retrieval of approximate shortest
paths in sparse graphs. Thorup and Zwick present lower bounds (and an
almost matching upper bound) on the trade-off for general graphs. The hard
cases that enforce their lower bound, however, are rather dense graphs. We
show that for sparse graphs, it is possible to get significant improvements
in the trade-off between size of the data structure and the path lengths
retrieved using the data structure. In particular, for weighted undirected
graphs with n nodes and average degree \Delta, we present the following two
data structures:

- A data structure, that for any 0 < \varepsilon \leq 1/2, is of size
O(n^{2-\varepsilon} \Delta^{1 -\varepsilon}) and returns distances with
approximation ratio at most 2 in time O((n\Delta)^{\varepsilon}).

- A data structure, that for any 0 < \varepsilon < 1 and any positive
integer k, is of size O((n \Delta)^{(1 + 1/k)(1 - \varepsilon)}) and
returns distances with approximation ratio at most (4k-1) in time
O((n\Delta)^{\varepsilon}).

Moreover, supported by large-scale simulations on graphs including the
AS-level Internet graph, we argue that the first scheme would be simple and
efficient to implement in practice as a distributed compact routing
protocol."

ABSTRACT="Buildings are known to be the largest consumers of electricity in the
United States. While there can be several subsystems that can dominate
depending on use modalities of buildings, often the largest electricity
consumer is the air- conditioning and ventilation (HVAC) system. Despite
this fact, in most buildings the HVAC system is run using fairly primitive
control algorithms based on fixed schedules of people within the buildings
causing wasted energy during period of low occupancy. In this paper we
present a novel HVAC control architecture that uses real-time occupancy
information to guide a building HVAC system, effectively enabling
buildings to be `duty-cycled' aggressively to save energy. We have deployed
our occupancy sensor network across an entire floor of a university
building and our data shows several periods of low occupancy with
significant opportunities to save energy. Furthermore, by interfacing with
the building Energy Management System (EMS) directly and using the
real-time occupancy data collected by our occupancy sensors we measure
energy savings of up to 20\% in the HVAC system of our building."

ABSTRACT="Telecommunications networks, and in particular optical WDM networks, are
vulnerable to large-scale failures of their infrastructure, resulting from
physical attacks (such as an Electromagnetic Pulse attack) or natural
disasters (such as earthquakes or floods). Such events happen in specific
geographical locations and disrupt specific parts of the network but their
effects are not deterministic. Therefore, we provide a unified framework to
model the network vulnerability when the event has a probabilistic nature,
defined by an arbitrary probability density function. Our framework
captures scenarios with a number of simultaneous attacks, in which network
components consist of several dependent sub-components, and in which either
a 1+1 or a 1:1 protection plan is in place. We use computational geometric
tools to provide efficient algorithms to identify vulnerable points within
the network under various metrics. Then, we obtain numerical results for
specific backbone networks, thereby demonstrating the applicability of our
algorithms to real-world scenarios. Our novel approach would allow
identifying locations which require additional protection efforts (e.g.,
equipment shielding). Overall, the paper demonstrates that using
computational geometric techniques can significantly contribute to our
understanding of network resilience."

ABSTRACT={Push message delivery, where a client maintains an {"}always-on{"}

the World Wide Web is not scalable for servers, intermediate network
elements, and battery-operated mobile device clients. We present a
measurement analysis of a commercially deployed WWW push email service to
highlight some of these issues. Next, we suggest content-based optimization
to reduce the always-on connection requirement of push messaging. Our idea
is based on exploiting the periodic nature of human-to-human messaging. We
show how machine learning can accurately model the times of a day or week
when messages are least likely to arrive; and turn off always-on
connections these times. We apply our approach to a real email data set and
our experiments demonstrate that the number of hours of active always-on
connections can be cut by half while still achieving real-time message
delivery for up to 90\% of all messages.}

ABSTRACT="With the proliferation of multicore and manycore architectures, memory
hierarchy plays an important role in realizing expected performance of
memory intensive scientific applications. A vast majority of scientific
applications require a priority based data structure to discriminate among
available data elements; for instance, a priority based data structure is
imperative for extracting the earliest events in a discrete event
simulation, identifying urgent tasks in a parallel scheduler, or exploring
most promising sub-problems in a state-space search. Traditional priority
based data structures are tree-based that makes them cache unfriendly due
to the exponentially increasing distance between parent and child nodes.
Fine grained large-scale applications further cause excessive contention
among competing processors due to frequent updates. In this dissertation we
propose a priority based data structure that adapts to the memory hierarchy
of the underlying computer system. The top priority items are aggregated
and kept into a working subset of data items that is readily accessible for
processing."

technique, proves in-efficient for VLOB Iris code database objects. With
technology growth the bit granularity has improved. This has resulted in
more accuracy due to higher bit density. This high granularity leads to
variable size IRIS codes rather than fixed sized IRIS codes hence
adaptively is one major challenge. This paper proposes a novel, adaptive
IRIS code database organization and searching algorithm proposing the
improvement in template similarity matching process. The algorithm reduces
the redundant IRIS code comparisons resulting in faster searching speed.
For the IRIS that has accumulated the cataract, HD methods shows major

ABSTRACT="Codes constructed as subsets of the projective geometry of a vector space
over a finite field have recently been to have applications as random
network error correcting codes. If the dimension of each codeword is
restricted to a fixed integer, the code forms a subset of a finite-field
Grassmannian, or equivalently, a subset of the vertices of the
corresponding Grassmannian graph. These codes are referred to as codes on
finite-field Grassmannian or more generally as subspace codes.

In this paper, we study fundamental limits to list decoding codes on
finite-field Grassmannian. By exploiting the algebraic properties of the
Grassmannian graph, we derive a new lower bound on the code size for the
first relaxation of bounded minimum distance decoding, i.e., when the
worst-case list size is restricted to two. We show that, even for small
finite field sizes and code parameters, our bounds demonstrate improvements
in code size when compared to bounded minimum distance decoding."

specifications. Nibble processing of the filter coefficients is performed
to achieve computational efficiency. Quantization of the filter coefficient
is used as a trade-off for the filter design. Twelve-bit quantized
coefficients are used to obtain low hardware cost with satisfactory filter
performance. Matlab simulation is used to compare and contrast the
performance of an RRC filter with that of a standard floating point design.
Hardware of the filter is simulated and synthesized using Xilinx ISE10.1.
Implementation results show a 25\% savings in LUT count. The use of nibble

which can improve the performance of the cycloconverter. Increasing of the
maximum output/input voltage transfer ratio of converter up to 1.5 is one
of the main advantages of the proposed cycloconverter. In addition, there
is no restriction for generation of output frequency consequently; the
proposed cycloconverter can be applied as both step-up and step down
converters. The control strategy of cycloconverter is based on pulse width
modulation (PWM) method. Using PWM based control strategy, the injected
harmonics will be produced around the switching frequency and its multiple
coefficients and the size of filters will be decreased. Also, a feedback of
output voltage is used in the control strategy of the proposed converter to

separate line and load bridges. In the inverter stage, the predictive DTC
method is employed. In the rectifier stage, in order to reduce losses
caused by circuit snubber the rectifier four-step commutation method is
employed. The simulation results of predictive DTC system based on IMC
confirms its effectiveness and accuracy."

measurement and a fuzzy majority opinion aggregator for a multi criteria
decision making (MCDM) problem. The rating of each alternative and the
weight of each criterion is described by linguistic terms which can be
expressed in triangular fuzzy numbers. We introduce a new distance metric
by using graded mean integration representation of triangular fuzzy
numbers. The concept of majority opinion gives an overall opinion which
synthesizes the opinions of the majority of the decision makers. Fuzzy
majority opinion aggregator is used to make a consensual judgment
synthesizing the individual opinions. To clarify our proposed method, a
numerical example is discussed. Results show that our proposed algorithm is
more advantageous in reflecting opinions of the majority of decision makers
and also provides more confidence for their decisions."

ABSTRACT="In this paper we present a method of localizing multiple wideband acoustic
sources based on both signal attenuation pattern and delays in the
reception of the signal. Moreover, an additional order of flexibility is
added to the problem by considering the attenuation model as an unknown
function with reasonable prior assumptions about its functional space. Such
approach is capable of enhancing the localization performance compared to
when only the signal attenuation data or the time delays are used. A cost
function is then formed in terms of the sources locations and the
attenuation model parameters. Having different types of unknowns in the
cost function, convergence concerns, and the advantage of using trust
region methods encourages using the Levenberg-Marquardt algorithm.
Accordingly, to simplify the implementation of the proposed algorithm,
methods of calculating the Jacobian are provided. Finally the validity of
the proposed method is verified by providing simulation results."

paper, we present a CS-based framework for demosaicing the general class of
periodic CFAs. It is known that periodic CFAs feature the ability of
separating luminance and chrominance bands in the frequency domain. This
feature helps reduce the coherency between luminance and chrominance
components of the projection matrix, which in turn improves the probability
of finding a unique solution. We exploit this feature to propose a novel
dictionary design framework at the solver side. Specifically, our design
paradigm follows the observation that the chrominance channel is smooth in
the spatial domain and is sparse when represented in an overcomplete color
space. We show that further improved results can be achieved for most
periodic CFAs under the proposed framework."

ABSTRACT="As peer-to-peer (P2P) applications (e.g. BitTorrent) impose high costs to
Internet Service Providers (ISPs) due to the large volumes of inter-domain
traffic generated, extensive research work has been done concerning
locality-awareness approaches. Although such approaches are based on
properties of the physical network topology, they take very little
consideration of the real business relationships between ISPs (peering and
transit agreements) as well as of the heterogeneous peer distributions
among ISPs. In this paper, we propose an innovative way to exploit the
business relationships between ISPs of either the same or different Tiers,
by introducing new collaborative approaches for overlay traffic management
on top of the locality-awareness ones. By means of simulations, we show
that win-win situation (reduced transit traffic for ISPs and better
performance for users) can mostly be achieved under certain complicated
collaborative approaches. Also we show how the collaboration between the
upper Tier ISPs can affect favorably both the inter-domain traffic in the
transit links, where charging applies, and the performance of their
customers ISPs and how the latter can benefit from their collaboration with
the transit ISPs."

ABSTRACT="There is a clear trend towards using cloud resources in the scientific or
the HPC community, with a key attraction of cloud being the elasticity it
offers. In executing HPC applications on a cloud environment, it will
clearly be desirable to exploit elasticity of cloud environments, and
increase or decrease the number of instances an application is executed on
during the execution of the an application, to meet time and/or cost
constraints. Unfortunately, HPC applications have almost always been
designed to use a fixed number of resources. This paper describes our
initial work towards the goal of making existing MPI applications elastic
for a cloud framework. Considering the limitations of the MPI
implementations currently available, we support adaptation by terminating
one execution and restarting a new program on a different number of
instances. The components of our envisioned system include a decision layer
which considers time and cost constraints, a framework for modifying MPI
programs, and a cloud-based runtime support that can enable redistributing
of saved data, and support automated resource allocation and application
restart on a different number of nodes. Using two MPI applications, we
demonstrate the feasibility of our approach, and show that outputting,
redistributing, and reading back data can be a reasonable approach for
making existing MPI applications elastic."

with a finite number of mass points. Numerically we observe that at
low-SNR, the capacity achieving distribution has two mass points with one

method automatically preserves the appearance, passing surface properties
such as normals or colors from a highresolution model to its simplified
version. Surface properties of the original model are projected onto a
quadrilateral domain defined by a collection of cubic cells, and then these
properties are stored into a 2D texture. Later in the rendering process,
surface properties are mapped from the texture onto the simplified model.
The main contributions are: a parameterization for arbitrary surfaces based

ABSTRACT="Intermittent behaviour (movement interspersed with pauses) is a broad
biological phenomenon and is observed in organisms ranging from protozoans
to mammals. We depict a coordination problem that is part of the general
structure of intermittent behaviour: the adjustment-deployment dilemma.
This dilemma captures the difficult compromise between the time spent in
adjusting a response and the time used to deploy it: the adjustment process
improves fitness with time but we also assume that such fitness decays with
time (e.g. environmental conditions change), if you spend very little time
adjusting the fitness of the action is poor, but if you spent too much time
before deployment the result is no longer valid. We provide a mathematical
model of the dilemma, general enough to be applicable to different
instances of it. An optimal solution is then simulated and analysed, the
result shows that the optimal strategy is the one that maximizes the number
of interactions with the environment. We explore the biological
significance of such results and provide a minimal mechanism capable to
instantiate an optimal solution. We conclude with a summarize of the
contributions of the present work and suggest potentially fruitful areas of
future work."

ABSTRACT="In recent times it has been shown that Multiple Input Multiple Output

of antennas at both transmitter (Tx) and receiver (Rx) the communication
link has a better chance of being carried out end to end. Unfortunately,
when the system is physically deployed, it has the disadvantages of
increasing the implementation costs and the complexity involved due the
increase of RF chains. However, there are several algorithms proposed for
overcoming such challenges and one of them consists in the selection of a
sub-set of antennas which main objective is to maintain the benefits of
MIMO at an affordable trade-off of complexity and implementation cost. This
article proposes a novel model for antenna selection which is able to
achieve similar results to the optimal selection in terms of performance
and significantly surpassing other algorithms in both performance and

ABSTRACT="Although the design of exascale architectures is still an intensive
research and development topic, one of the major trends we may expect is
the use of multicore nodes enhanced with GPU accelerators. Exploiting all
resources of an hybrid accelerators-based node at their maximum potential
is thus a fundamental step towards exascale computing. In this article, we
present the design of a highly efficient QR factorization for such a node.
Our method is in three steps. The first step consists of expressing the QR
factorization as a sequence of tasks of well chosen granularity that will
aim at being executed on a CPU core or a GPU. We show that we can
efficiently adapt high-level algorithms from the literature that were
initially designed for homogeneous multicore architectures. The second step
consists of designing the kernels that implement each individual task. We
use CPU kernels from previous work and present new kernels for GPUs that
complement kernels already available in the MAGMA library. We show the
impact on performance of these GPU kernels. In particular, we present the
benefits of new hybrid CPU/GPU kernels. The last step consists of
scheduling these tasks on the computational units. We present two
alternative approaches respectively based on static and dynamic scheduling.
In the case of static scheduling, we exploit the a priori knowledge of the
schedule to perform successive optimizations leading to very high
performance. We however highlight the lack of portability of this approach
and its limitations to relatively simple algorithms on relatively
homogeneous nodes. Alternatively, by relying on an efficient runtime
system, StarPU, in charge of ensuring data availability and coherency, we
can schedule more complex algorithms on complex heterogeneous nodes with
much higher productivity. In this latter case, we show that we can achieve
high performance in a portable way thanks to a fine interaction between the
application and the runtime system."

ABSTRACT="Tuning numerical libraries has become more difficult over time, as systems
get more sophisticated. In particular, modern multicore machines make the
behaviour of algorithms hard to forecast and model. In this paper, we
tackle the issue of tuning a dense QR factorization on multicore
architectures using a fully empirical approach. We exhibit a few strong
empirical properties that enable us to efficiently prune the search space.
Our method is automatic, fast and reliable. The tuning process is indeed
fully performed at install time in less than one hour and ten minutes on
five out of seven platforms. We achieve an average performance varying from
97\% to 100\% of the optimum performance depending on the platform. This
work is a basis for autotuning the PLASMA library and enabling easy
performance portability across hardware systems."

optimizing the weighted sum-rate is more meaningful. Moreover, MIMO X
channel subsumes the MIMO interference channel, MIMO multiple access, dual
MIMO point-to-point and MIMO broadcast channel. In this respect it is
desirable to have an algorithm to design the proper linear transmitters and

able to provide MMSE precoders attaining significant gains in terms of SNR

ABSTRACT="Reinforcement learning (RL) algorithms are powerful tools that can be used
to solve multi stage decision making problem. In this paper, we view
Economic Dispatch (ED) problem as an n stage decision making problem and
propose a novel RL algorithm which uses pursuit algorithm for making
decisions at each stage during the learning process. Even though many soft
computing techniques like simulated annealing, genetic algorithm and
evolutionary programming have been applied to ED, they require searching
for the optimal solution corresponding to each demand. In RL approach, once
learning phase is over, we can find optimal dispatch for any load from a
lookup table. One important issue in RL algorithm is striking a balance
between exploration and exploitation during the learning phase. Here we
propose to use an efficient algorithm called pursuit algorithm from theory

ABSTRACT="Reinforcement Learning (RL) has been applied to various scheduling and
control problems in power systems in the last decade. However, the area is
still in its infancy. In this paper, we present various research work in
this area in a unified perspective. In most of the applications, power
system problems - control of FACTS devices, reactive power control,
Automatic Generation Control, Economic Dispatch, etc - are modeled as a
multistage decision making problem and RL is used to solve the MDP. One
important point about RL is it takes considerable amount of time to learn.
However, RL can learn off line using a simulation model. Once the control
strategy is learned decision making can be done almost instantaneously. A
major draw back of RL is most of the application does not scale up and much
work need to be done. We hope this paper will generate more interest in the
area and RL will be utilized to its full potential."

that the optimum beamforming solution results in a degraded capacity when

weights. Factoring the HPA effects in the beamforming weights, the capacity
of the nonlinear MIMO channel reaches its linear channel equivalent."

each group, some nodes are selected as monitor nodes, which cooperate with
each other to compose a global normal profile. Every monitor node
establishes a subprofile of its own normal network traffic using principal
component analysis (PCA) and sends it to other monitor nodes. Every monitor
node composes the global normal profile based upon all received subprofiles
and uses it to detect anomalies in its own network traffic. As the normal
network behavior changes over time, the global normal profile is updated.
We demonstrate that PCADID achieves a high detection rate with a low false
alarm rate, while minimizes the communication overhead and energy
consumption in the network."

One of the main steps which has to be faced in designing WR networks is the

due to the complexity of the MILP approach we propose a greedy heuristic

ABSTRACT="In this paper, a novel fault location method for three terminal power
transmission lines is proposed. This algorithm is based on the TT-transform
for extracting the high frequency components of the current signal
generated by the fault. By applying this transformation to different modes
of current signals at all terminals, the arrival of travelling waves of
current signal from the fault point to each terminal is inspected, whereby
the fault location and fault section can be estimated. After simulating
different fault conditions by ATP/EMTP software, MATLAB is used for
processing fault data and calculating fault location. Various conditions
and problems that maybe faced with fault location are considered in paper."

decoder is able to calculate a symbol-wise function of a sequence available
only at the encoder and a sequence that can be measured only at the

here by including two new aspects: (i) The decoder obtains noisy
measurements of its sequence, where the quality of such measurements can be
controlled via a cost-constrained {"}action{"} sequence; (ii) Measurement
at the decoder may fail in a way that is unpredictable to the encoder, thus
requiring robust encoding. The considered scenario generalizes known
settings such as the Heegard-Berger-Kaspi and the {"}source coding with a

in relevant special cases, along with general upper and lower bounds.
Numerical examples are also worked out to obtain further insight into the

cryptosystem reveals that it has serious security flaws. Consequently, it
is susceptible to a number of attacks. In this paper, the cryptanalysis of
original cryptosystem is presented and it is shown that the attacker can

ABSTRACT="The Path Computation Element (PCE) is a network entity utilized for network
path computation operations, especially useful in optical networks based on
wavelength division mul-tiplexing (WDM). In the PCE paradigm, the
communication be-tween a node and the PCE is specified by the Path
Computation Element Communication Protocol (PCEP). According to PCEP
protocol, multiple LSP (Label Switched Path) requests can be bundled
together before being sent to the PCE in order to reduce the control
overhead. Multiple bundles received by the PCE can then be provisioned at
once as a single bulk. Enabling bulk provi-sioning of LSP requests at the
PCE in a concurrent manner can bring significant improvements in terms of
higher network re-source utilization and control plane overhead reduction.
However, these advantages come at a cost of a longer connection setup-time
and of an instantaneous increase in the network load, which may lead to a
degradation of the network performance, e.g. blocking probability. In order
to address the importance of WDM network surviva-bility this paper aims at
exploring pros and cons of enabling the LSP requests bulk provisioning at
the PCE in a network scenario with shared path protection (SPP). This
objective is achieved by comparing sequential and concurrent path
computation strate-gies. An efficient meta-heuristic named GRASP\_SPP\_BP
(Greedy Random Adoptive Search Procedure for Shared Path Protection with
Bulk Provisioning) is proposed for concurrent provisioning of primary and
shared backup path pairs for each request. GRASP\_SPP\_BP minimizes the
backup resource consumption while requiring minimal path computation time.
The presented results demonstrate that, in a SPP network scenario, a
significant reduction in the PCEP control overhead, network blocking
probability and backup resource consumption can be achieved via LSP bulk
provisioning at the PCE with the proposed GRASP\_SPP\_BP approach."

vary from each other to a great extent, which implies that the propagation
channel effect is unfairly distributed on the users. Applying different
types of frequency interleaving mechanisms, we show that the choice of
interleaving can ensure better BER fairness on an individual user basis. In
particular, by introducing the application of cyclically shifted random

ABSTRACT="A sliding mode controller can tackle nonlinear system's uncertainties and

vibrations in drilling strings is a good example where variable structure
control could be used. However, the discontinuous control signal causes
significant problems of chattering and does not provide a smooth control
signal to the top-drive or rotary table system used on drilling rigs. This
control signal might practically place the top-drive under loads of
oscillatory torque and it might jeopardize its safety. A chattering free
sliding-mode controller optimized using a Particle Swarm Optimization (PSO)
routine is proposed to avoid bit sticking phenomena and in addition,
provide a smooth control signal to the top drive system. In this work, a
discontinuous lumped-parameter torsional model of four degrees of freedom

ABSTRACT="Efficient management of network traffic is one of most challenging research
areas in Mobile Ad Hoc Networks (MANETs). It becomes even more challenging
for human involved and information sensitive MANET applications (e.g,
public safety applications). For example in a MANET-assisted road safety
system, witnesses of a road accident may introduce numerous redundant
information over the network through their hand-held mobile devices.
However, sometimes these generated information are not exactly identical
but they can be syntactically or conceptually similar. Therefore, in order
to reduce such traffic load in the network, this paper proposes a novel
semantic scheme. This semantic scheme identifies the aforementioned
semantic similarity and accordingly remove the information redundancy. The
proposed scheme is facilitated by employing the well-known Latent Semantic
Indexing (LSI) algorithm. Simulation results confirm the usefulness of the
proposed technique in reduction of similar traffic in the network."

ABSTRACT={In Wavelength Division Multiplexed (WDM) networks with dynamic lightpath
provisioning, connection requests needs to be served without any prior
knowledge of their arrival and departure times. As time passes, network
resources may become fragmented because of the network dynamism. Under
these circumstances it is highly beneficial to re-optimize (i.e.,
de-fragment) the existing lightpath configuration at some specific time
instances to better utilize the available network resources and
consequently reduce the risk that future connection requests will be
blocked. Assuming that this de-fragmentation occurs dur-ing a
re-optimization phase, this paper explores a set of strategies which govern
the time instances when this re-optimization phase should be triggered as
well as a set of strategies to decide which of the currently active
lightpaths should be optimized at any given re-optimization phase. These
strategies are referred to as when-to-re-optimize (when-t-r) and
what-to-re-optimize (what-t-r) strategies, respectively. During the
evaluation process particular attention is devoted to study the impact that
when-t-r and what-t-r strategies have on the traffic disruption metrics
(i.e., number of total disrupted connections, disruption time,
reconfiguration time) inherent with the re-optimization process. Based on
the evaluation results, it can be concluded that there is not a univocal
answer and that the choice of an optimal {"}when{"} and an optimal
{"}what{"} to re-optimize strategy is dependent upon the performance
objective (e.g. lower blocking probability or network disruption) in a

larger than resources available at hand in an enterprise and it would like
to outsource it for high speed computation or data management requirements.

archiving resources as per demand. Cloud computing is a new paradigm which
may be used to handle such situations. It offers a virtual environment at a
small initial investment by entrepreneurs planning to develop large
applications scalable as the scope and workload increases. The computer
hardware and software are available in virtualized environments of cloud
computing offering Software as a Service (SaaS), Infrastructure as a

ABSTRACT="In this study, we analyze the role of interleavers in OFDMA system for
ensuring uniform BER performance amongst the active users and also
investigate their respective PAPR properties. At first considering a
generic system in a slowly changing multipath channel where high dispersion
in the individual users performance exists, we apply different types of
interleaving and show that they in general helps in achieving fairness. In
particular, by introducing the application of cyclically shifted random
interleaver, we demonstrate its effectiveness in achieving BER fairness
over others (dispersion in individual users BER reduced by 89\% compared to
no interleaving at 15dB SNR). Then we explore the comparative performance
of different interleavers at varying active user density considering a
system based on the IEEE 802.16 standard specifications. Finally, for a
generic OFDMA, we investigate the PAPR distribution of different
interleavers as the system moves from low to high user loads. Based on the
results, we conclude that for a heavily loaded system, cyclically shifted
random interleavers can effectively ensure uniform performance amongst
active users with reduced system complexity and manageable PAPR."

ABSTRACT={Multi-core processor architectures, also known as chip-multiprocessors
(CMPs), have become a predominant technology for applications demanding
both the high bandwidth and the low power. A typical CMP architecture
integrates multiple processor cores, one or more memory controllers, a
multi-level cache hierarchy, and an interconnection network on a single
chip. Sharing of large size cache among multi-cores poses a number of new
challenges to be addressed in terms of cache-coherence and power
management. This paper investigates the integration of a directory-based
cache coherence protocols for the last level shared cache (L2/L3) for
power-aware CMP architectures. We propose a scalable directory-based cache
coherence protocol with minimal hardware overhead. The protocol supports
the {"}sleep{"} mode for one or more cores without running into issues of
data inconsistencies of shared data. The paper also presents the framework
of an analytical model to evaluate the performance of the proposed
protocol.}

time period T. Our goal is to achieve (alpha,T)-coverage by a minimal set
of mobile sensor nodes for a given AoI, coverage ratio alpha, and time
period T. We model pedestrians as mobile sensor nodes moving according to a
discrete Markov model. Based on this model, we propose two algorithms: the
inter-location and inter-meeting-time algorithms, to meet a coverage ratio
alpha in time period T. These algorithms estimate the expected coverage of
the specified AoI for a set of selected nodes. The inter-location algorithm
selects a minimal number of mobile sensor nodes from nodes inside the AoI
taking into account the distance between them. The inter-meeting-time
selects nodes taking into account the expected meeting time between the
nodes. We conducted a simulation study to evaluate the performance of the
proposed algorithms for various parameter setting including a realistic
scenario on a specific city map. The simulation results show that our
algorithms achieve (alpha,T)-coverage with good accuracy for various values

challenges. 

One of the biggest challenges faced by the Indian education system is
motivating teachers and reinstating their position in society. EduMedia's
survey reveals that teachers face many difficulties. Our system lacks
quality training modules for teachers. The need of the hour lies in
initiating scalable and impactful teachers training modules that can be
implemented with ease. 

Films have a tremendous impact on our society, they are a great medium to
express and communicate thoughts and feelings. When films are combined with
creatively designed worksheets with psychological inputs, they make a
formidable learning experience. 


Leveraging on the powerful impact of films, we at EduMedia India Pvt. Ltd.
have introduced School Cinema - a well researched film-based learning
module supported by a fun and exciting workbook/worksheets designed to
introduce and reaffirm life-skills and values and act as a training aid to

information. It decomposes the noisy image into Gabor coefficients of
different scales and orientations. Denoising is performed in the transform
domain by thresholding the Gabor coefficients with phase preserving
threshold and non-phase preserving threshold where both approaches have
been formulated as adaptive and data-driven. For the non-phase preserving
approach the BayesShrink thresholding methods have been used. Finally using
the thresholded Gabor coefficients of each channel the denoised image has
been formed. It has been found that for smoothly varying images the
modified BayesShrink method outperforms both the BayesShrink and the phase
preserving approaches whereas for images with high variations the phase
preserving approach performs better."

ABSTRACT="Since network coding is very useful for increasing the total throughput in
wireless networks, it has recently gained much attention. However, there is
few works focusing on network coding in the cyclic topology network, in
which six nodes are connected to form a cluster. Considering the case that
each node's regional information is required to be exchanged among all the
nodes in the cyclic network, we proposed a heuristic multicast scheduling
scheme. At each time slot, only the designated group of nodes can transmit
data simultaneously. For this reason, we considered the distributed power
control to reduce interference. With our proposed scheme, it can be shown
that the total throughput is substantially improved using wireless network
coding. In addition, we analyzed the appropriate range of node locations,
from which we can evaluate the corresponding system performance. Finally,
the simulation results indicate that if the nodes are distributed almost
evenly in an area, lower energy consumption and improved throughput can be
achieved."

DVS cameras only respond to pixels with temporal luminance differences,

be directly applicable in DVS based applications. This paper attempts to

localization algorithms can be divided into range-free or range-based based
on whether the range information. Due to the hardware limitations of
devices, range-based algorithms are being pursued as a cost-effective
alternative. DV-hop is one of the range-free localization algorithms using
equal per-hop distance. However, DV-hop cannot precisely estimate the
distance between an anchor and a sensor nodes since it just uses hop-count
which is increased by 1 to calculate per-hop distance. Thus, per-hop
distance must be equal even though the actual distance of each hop is
totally different. In this paper, each node emits multi-power beacon
signals so the range of signals is different and the signals are used by
criterion of per-hop distance. So, we can estimate the distance more
accurately. As a result of simulations, our proposed algorithm outperforms
DV-hop, 11.57\%R. In the case of noisy environment, the proposed algorithm
demonstrates noticeable improvement as the number of signals is increasing"

parameter in recent research works due to the global climate change and
growing demand for very high data rates in future cellular systems. In our
work, the main objective is to reduce the area energy consumption in a
cellular network, for a given average spectral efficiency, in order to
realize the green radio transmissions. The energy consumption for different
transmission schemes such as direct link, decode and forward (DF) relaying
with and without network coding is compared in this regard using a linear
power consumption model. The impact of different parameters such as cell
radius, the number and position of deployed relays and target spectral
efficiency is studied for each transmission scheme. It has been concluded
that DF relaying in general, provides moderate power savings as compared to
the direct link transmission. Moreover, for a given outage probability, the
network coding at the relay extends the cell coverage and provides higher
spectral efficiency as compared to the conventional DF relaying and the
direct transmission."

deconvolution approaches. This restored image gives a better representation
of the real 3D surface of the measured sample than the original distorted
image. In this paper, we propose a method for estimating the
three-dimensional shape of the AFM tip by measuring a micro-cylinder with
a-priori known dimensions. The estimated tip shape is then used to restore
subsequent AFM images, when measured with the same tip, under similar
measurement conditions. Significantly, the impulse response of the AFM can
be deduced using this method. The suitability of this novel approach for
restoring AFM images is confirmed using computer simulation and also with

problems represent an important category of these problems and are governed

and analyst turn to approximate solutions in a certain range of accuracy.
The present paper concerns the particular problem of hydrodynamic bearing
lubrication governed by the well-known Reynolds equation. Among numerical
techniques employed for hydrodynamic bearing analysis, the finite
difference method has been applied earlier in the sixties and the finite
element procedure has been tested in the seventies. Both methods have been
extended after to get reliable results. In the current work, an attempt is
