ABSTRACT="In this paper, we focus on the dynamic spectrum 
access of two infrastructure-based cognitive radio 
networks, primary network and secondary network, 
which are collocated with each other. To improve 
network performance of two networks,
we propose a cooperative communication-aware 
spectrum leasing framework, in which, primary 
network leverages secondary users as cooperative 
relays, and decides the optimal strategy on the 
relay selection and the price for spectrum leasing. 
Based on primary network’s strategy, secondary 
network determines the
length of spectrum access time it purchases from the 
primary network. Finally, each network allocates the 
total spectrum access time of the network among its 
end users. The above sequential decision procedure 
is formulated as a Stackelberg game, with primary 
network acting as the leader and secondary
network as the follower, and a unique Nash 
Equilibrium (NE) point is achieved through backward 
induction analysis. At this NE point, both networks 
maximize their utilities in terms of transmission 
rate and revenue/payment. Meanwhile, the optimal 
relay selection and spectrum resource allocation 
among all the
users are also derived based on the Nash 
Equilibrium. Simulation results show that both 
primary and secondary networks achieve higher 
utility by exploiting cooperative transmission under 
our proposed framework, which gives both networks 
incentive for cooperation."

been increased and efficiency of spectrum usage has been important issues
in the wireless industry. Therefore recently, there have been many efforts
on changing spectrum management framework based on the market mechanism.
This research analyzes three different mechanisms as an alternative of
secondary trading framework; a brokerage mechanism, auctions and a direct

ABSTRACT="Recent development in the field of Wireless communications and electronics
has enabled the deployment of Wireless sensor Networks (WSNs) in an
expanding variety of applications. Significantly, wireless communications
have demonstrated profound significance in a variety of applications
ranging from military to health applications and from home to industry. In
WSNs, a major goal is conserving the sensor nodes' energy and thus
maximizing the network lifetime. Several energy efficient routing protocols
have been proposed in the literature. However, in these protocols, a path
is selected based on the local energy view of a sensor node. In this paper,
we propose an energy-efficient routing protocol that selects a
communication path based on the global energy view of the network. The path
selection criterion is based on an energy-weight function to reflect how
balanced is the energy distribution among all nodes along the path. The
energy weight function estimates the energy weight of different paths and
the communication path with the best energy weight is selected. Simulation
results indicate clearly that compared to the routing protocol proposed in
[9], our proposed protocol distributes the energy consumption evenly among
the network nodes and thus maximizes the network life time."

ABSTRACT="Wireless sensor network (WSN) is increasingly being used in a variety of
applications which include habitat monitoring, smart health care system,
building automation, to name a few. Many approaches were developed for all
protocol layers, but an energy-efficient Medium Access Control (MAC) layer
remains a key design challenge. MAC with scheduled based architecture
provides greater advantage over other design, such as contention-based and
frequency division multiple access, in terms of minimizing packet
collision, overhearing, idle listening, and over emitting. Reliable and
energy efficient data transmission are required to prolong the network
lifetime. This paper presents the testbed development of an enhanced
lightweight medium access (eL-MAC) protocol which introduces distributed
time slot assignment and slotting communication mechanism. Therefore, with
eL-MAC, idle listening, overhearing and hidden terminal will be eliminated
where nodes transmit in its own time slot and sleep in other time slot if
there is no activity. This will reduce energy consumption as nodes are
active when transmitting and receiving and idle only in the beacon session.
The testbed developed consists of 9 TelosB sensor nodes programmed with
TinyOS. NesC programming language was used to implement the protocol in the
WSN module. Experimental results were compared to the results obtained from
simulation. As expected, there is a slight degradation in throughput and
packet received ratio in the experiment but is consistent for all values.
This concludes that the experimental testbed developed reflects the eL-MAC
protocol and has been successfullly implemented."

ABSTRACT="Many research works have been carried out in differentiated Services, to
study the fairness issues between aggregates of both TCP and UDP. Due to
multimedia demands, the UDP flows can also demand assured service. Hence,
there is a need to protect certain UDP flows which require the same fair
treatment as TCP. In such cases, the UDP flows are characterized as AS UDP
with target rates and are modeled as CBR sources with fixed traffic rate.
In such situations, to study the fairness issue, what should be the CB Rate
of the traffic is a question. With a goal to enlighten this, simulations
have been carried out with fixed target rates and varying CB rates. The
simulations are carried out with the time sliding window based two color
marker in NS-2 and their corresponding results being furnished. It is
inferred that the CBR should be set at a value greater than the target rate
of the UDP source to study its performance and fairness issues."

ABSTRACT="Background/aims: Human pluripotent stem cells are foreseen as a promising
source material for in vitro modeling and future transplantation therapies.
Isolation and culturing of human embryonic stem (hES) cells were first
reported just over a decade ago and since then a lot of research has been
conducted to maintain undifferentiated hES cells in defined, controlled
culture environment as well as to controllably differentiate the cells into
various cell types of the human body. One of the interesting research areas
has been the neural differentiation of hES cells and the potential of
produced neural cells in treating various neurological diseases and traumas
such as Parkinson’s disease, spinal cord injury, and ischemic stroke.
These diseases have huge negative impact in our society but effective and
curative treatments are not discovered yet regardless of the intensive
research conducted with various applications. The new significant discovery
in stem cell field was the invention of human induced pluripotent stem
(hiPS) cells a couple of years ago. These cells are originally
differentiated cells, e.g., skin fibroblasts which can be transfected
virally with 2-5 genes to form hES cell-like pluripotent cells. These cells
open up new possibilities for using patient’s own cells for e.g.
regenerative purposes. For now, however, the derivation and culture methods
of hiPS cells are far from being optimal and far from good manufacturing
practice (GMP) level. The use of these cells for in vitro modeling of
genetic diseases is currently a hot research area. HiPS cells have been
reported to differentiate to neural cells similarly as hES cells but the
electrical properties and functionality of these hiPS cell-derived neurons
has not been investigated. Here, our aim was to differentiate hiPS cells
into neuronal cells and study the network forming properties of these cells
with microelectrode array (MEA) setup. Methods: HiPS cells were
differentiated as neurospheres in neural differentiation medium. After 8
weeks of differentiation the neurospheres were manually cut into small
aggregates and plated into PEI and laminin coated standard MEA dishes
(MCS). Networks were recorded twice a week over time period of 4 weeks.
Finally pharmacological testing was performed. Control cells were plated on
polystyrene and immunostained with neuronal markers at the end of the
follow-up time. Results: One weeks after plating first single signal spikes
were detected and the signaling of the network further developed into
trains and even bursts during the next 6 weeks, as also reported for mouse
ES and hES cell-derived networks. Finally, the hiPS cell-derived matured
network responded to pharmacological stimuli as expected. The cells stained
positive for neuronal markers micro tubule associated protein 2 (MAP-2) and
β-tubulin3. Conclusions: In conclusion, hiPS cells can be differentiated
into neural cells which further are capable of forming functional neuronal
networks. This research area should be more carefully studied, however, if
designing the use of hiPS cells as neurological in vitro models or for
regenerative purposes."

width x 270 mm depth x 2325 mm length were tested to destruction under four
point bending. The variables are the number of carbon plies in a wet
laid-up scheme and the number of GFRP rods in a NSM scheme. The RC beams
were designed to have excess reinforcement in shear to allow the beams to
fail in bending. The flexural performance was assessed in terms of the
enhancement in the ultimate load carrying capacity, load-deflection
characteristic up to and beyond peak, initial stiffness, and strain
development in the RC beams, due to the attached carbon fiber reinforced
polymer (CFRP) sheets and GFRP rods. Test results show that the RC beams
strengthened with two (2) NSM GFRP rods recorded the highest of about 88\%
increase in strength capacity over the control beam and 34\% increase
corresponding to those of strengthened with a GFRP rod. The strength
capacity of the beam specimens strengthened with a rod and two (2) rods of
NSM GFRP recorded an ultimate load of about 62\% higher and 29\%
respectively than those beams strengthened with a layer and two (2) layers
of EB CFRP sheets. The higher performance enhancing ability of the NSM
strengthening scheme is therefore evident compared to that of the

ABSTRACT="In order to evaluate a vehicular network performance it is important to
develop and use mobility models that accurately capture the realistic
mobility characteristics of moving vehicles. In this paper, we present
performance evaluation of various routing protocols including SIFT, GPSR
and GOSR using different mobility models such as Random Waypoint Model
(RWM), Fluid Traffic Model (FTM) and Intelligent Driver Model with
Intersection Management (IDM-IM). We present simulation results that
illustrate the importance of choosing a mobility model in the simulation of
a vehicular network protocol. We illustrate how the performance results
considerably change as a result of changing the simulated mobility model.
We show how unreliable results can be obtained by using some models such as
RWM and FTM. In addition, we demonstrate how more realistic mobility models
such as IDM-IM often lead to more accurate results."

ABSTRACT="A critical issue in wireless sensor networks is represented by the limited
availability of energy within sensor nodes. An effective approach for
energy conservation is scheduling sleep intervals for extraneous nodes,
while the remaining nodes stay active to provide continuous service. Most
previous solutions assumed a perfect radio condition with a static,
circular coverage. However, in real situations, radio signals are very
dynamic and irregular in their coverage. This is especially true for
wireless sensor networks, which usually employ low quality radio modules to
reduce the cost. Assuming no location information is available, we approach
the problem in this paper from two aspects: space and time. We present a
topology control algorithm, termed OTC, for sensor networks with
consideration of radio irregularity and dynamic radio coverage. It uses
two-hop neighborhood information to select a subset of nodes to be active
among all nodes in the neighborhood. Each node in the network selects its
own set of active neighbors from among its one-hop neighbors. This set is
determined such that it covers all two-hop nodes. OTC is evaluated against
a well-known algorithm from the literature, namely Span through realistic
simulations using TOSSIM. The results show that under dense deployment and
irregular and dynamic radio coverage, our algorithm outperforms Span."

trajectory based routing (e.g., SIFT). We used VanetMobiSim/NS-2 to compare
the protocols performance under different node densities, speed and

ABSTRACT="The main design challenge for wireless sensor network solutions is energy
efficiency to prolong the network operable lifetime. Since most energy is
spent for radio communications, an effective approach for energy
conservation is scheduling sleep intervals for extraneous nodes, while the
remaining nodes stay active to provide continuous service. Assuming node
position information is unavailable we propose an algorithm to construct a
sparse spanner network topology for these networks. It uses two-hop
neighborhood information to select a subset of nodes to be active among all
nodes in the neighborhood. Each node in the network selects its own set of
active neighbors from among its one-hop neighbors. This set is determined
such that it covers all two-hop neighbors. Our proposed algorithm is proved
to achieve several desirable properties on both Euclidean and general
weighted graphs: (1) the resulting graph is symmetric and connected; (2)
the resulting graph also exhibits good spanner properties for both
distance/energy and hops; (3) it is constructed locally in a fully
distributed fashion; (4) we prove that on the average-case unit disk
graphs, the resulting topology features the bounded degree property; (5)
finally, the computation cost of our algorithm is at most O(n^3 ), and the
communication cost is bounded by O(n^2 )."

ABSTRACT="Background/Aims The present work tackles with the coupling of model neuron
networks with functionalized silicon surfaces and the integration of nano
field effect transistors to stimulate and record their activity (neuroFETs
project). The principal aim of this work is the fabrication of field effect
nano-transistors (nanoFETs) arrays for neural stimulation and/ or recording
in presence of neural noise. These nano-transistors are fabricated on SOI
wafers (Silicon-On-Insulator) using photolithography techniques. The
principle of functioning of these devices is the local variation of the
tension in the gap between the neuron and the substrate (transistor) and
this way the modulation of the conductance in the transitor channel. The
work of Patolsky et al. [1], after the seminal work of P. Fromhertz group
[2], has inspired this work. These authors measured neuron AP signals with
nanotransitors arrays built from silicon nanowires according to bottom-up
approach. Nevertheless, this method restricts the geometries of measurable
networks to straigth neuron chains. The main difference with our project
falls back on the fabrication approach since the top-down is well adapted
to looped neuron network topologies. Methods/Statisticd The device is
started on a uniformly boron implanted (1E17 to 1E19 at/cm3) SOI wafer
(SOITEC). NanoFETs arrays are fabricated using deep UV (DUV)
photolithography, electron beam lithography and reacting ion etching (RIE).
We summarize briefly the chip fabrication process in the fig 1. In a first
DUV photolithographic step, the contact pads and electrical tracks to
connect the transistors (source and drain) are defined by lift off process
of gold. In a second step more sophisticated electron-beam lithography is
used to define the silicon bridges (around 100 nm wide). This should
conform the nanoFET channels. Protected with the thin film Al mask, the top
silicon layer is etched by Reactive Ion Etching (SF6). It is well known
that a maturation of at least 1 week after neuron plating is necessary to
obtain fully differentiated active cells. NanoFETs arrays have to survive
at least this period of time with a high yield, while submerged into
culture medium maintained at 37°C. A possible solution could be a Si3N4 or
a parylen encapsulation layer to protect the surface. For the proper
placement of cells in the active zone area we use patterning adhesion
techniques based on UV lithography and lift off of poly-L-lysine (PLL) that
promotes the neuron adhesion to the surface. Finally a first module of a
specific electronic set-up consisting of 12 channels operating at a
sampling rate of 50kHz, where biphasic currents flowing into nanoFETs are
generated by microcontrolors and A/D converters, has been designed and
built to fully instrument a looped network made of 3 neurons.
Results/Summary Well-defined nanotransistors have been obtained by this
approach and first tests with neurons are still in progress. We have
performed preliminary experiments of contrast adhesion and subsequently
correct placement of soma and neuritic guidance in the active
nanofabricated zone area."

dichotomous, i.e. whether they are affected or not, we use logit regression
to identify the characteristics that have significant effect on the
different types of households' expenditures. Besides logit regression,
ANOVA and ANCOVA models were also regressed to capture the indirect effects
of the households characteristics on their expenditures. From the various

Through this research work the major factors leading to good practices in
knowledge management are identified and discussed. Eight main factors have

role in biological processes. Currently, much attention has been focused on
the production of chiral alcohols. Chiral alcohols such as

used in pharmaceutical industries for drug synthesis. There are many
factors that influenced the bioconversion which some of the crucial ones
include the pH of the media, biotransformation time, substrate
concentration, and agitation speed. All of these factors significantly
affect the percentage of enantiomeric excess as well as the percentage
conversion of the chiral alcohol. In this work, biocatalytic production of
(R)-1-(4-bromo-phenyl)-ethanol was achieved via asymmetric reduction of
1-(4-bromo-phenyl)-ethanone using the shake-flask method at the reaction
conditions of 30o C, 1mmol of substrate, agitation speed at 150rpm and at
various pH's. Since Aspergilus niger can easily grow, therefore, it was
used as a biocatalyst in the reaction. Based on the result attained, pH 7
gave the highest of enantiomeric excess (96\%) at the reduction time 48hr.
Meanwhile the best conversion achieved at pH 9 in which is 98\% conversion

Even if the physical proximity would give rise to a connected network, the
primary uses behavior could impact this connectivity. This aspect has a
significant impact on the design of routing protocols. We design a routing
scheme for cognitive radio ad-hoc networks, named Gymkhana, which is aware
of the degree of connectivity of possible paths towards the destination.
Gymkhana routes the information across paths that avoid network zones that
do not guarantee stable and high connectivity. To this aim we use a
mathematical framework, based on the Laplacian spectrum of graphs, that
allows a comprehensive evaluation of the different routing paths of the
cognitive radio network. Laplacian matrixes are used to compute the
connectivity of the different network paths. Gymkhana uses a distributed
protocol to collect some key parameters related to candidate paths from an
origin to a destination. The parameters are feeded into a basic
mathematical structure which is used to compute efficient routing paths.
Besides the basic idea of Gymkhana, the use of Laplacian matrixes to
derived a closed formula to measure the path connectivity is another

ABSTRACT="In Wireless Sensor-Actor Networks (WSANs), actors collect sensor readings
and respond collaboratively to achieve an application mission. Since actors
coordinate their operation, a strongly connected inter-actor network
topology would be required at all time. In addition, the path between
actors may have to be capped in order to meet latency constraints on the
inter-actor communication traffic. However, a failure of an actor may cause
the network to partition into disjoint blocks and would thus violate such
connectively goal. One of the effective recovery methodologies is to
autonomously reposition a subset of the actor nodes to restore
connectivity. Contemporary schemes in the literature rely on maintaining 1
or 2-hop neighbor lists and predetermine criteria for node’s involvement
in the recovery. However, 1-hop based schemes often impose high node
relocation overhead. In addition, the repaired inter-actor topology using
2-hop schemes often differs significantly from its pre-failure status and
some inter-actor data paths may get extended. This paper presents a novel
recovery algorithm that maintains the length of the current data paths in
the WSAN. The proposed Least-disruptive topology repair (LeDiR) algorithm
relies on the local view of a node about the network in order to devise a
recovery plan that relocates the least number of nodes and ensures that no
path between any pair of nodes is extended.  LeDiR is a localized and
distributed algorithm that leverages existing path discovery activities and
imposes no additional pre-failure communication overhead. LeDiR is
validated through simulation and is shown to outperform existing schemes."

ABSTRACT="We design a routing scheme based on an extension of the
algebraic connectivity for
cognitive radio ad hoc networks. We observe that a cognitive radio
network topology and its connectivity are highly influenced by the
behavior of primary users. Even if the physical
proximity of nodes would give rise to a connected topology, the
primary user behavior could impact the network connectivity. In
graph theory the second smallest Laplacian eigenvalue, i.e., the
algebraic connectivity, has numerous relationships with the graph
characteristics, including connectivity, diameter, mean distance of 
vertexes.
We then propose to compute the algebraic connectivity in a
cognitive scenario by deriving the average
Laplacian matrix of the network, averaged over the random activity
of the primary users, and compute the algebraic connectivity. On 
the basis of this
mathematical model we build up an utility function which is shown
to be effective for capturing some key characteristics of networks 
paths and can be used to compare them for routing purposes.
We then
design a routing scheme which, by modeling a path with a graph
and its Laplacian, captures the connectivity characteristics of
the path itself and suitably selects the best route in a uncertain
and high variable connectivity scenarios."

ABSTRACT="In multihop networks such as mobile ad hoc networks (MANETs), a node can
misbehave by selfishly dropping others' packets to save battery life. This
selfishness or misbehaviour can disrupt the whole network functionality and
can severely degrade network performance. Reputation based models have been
developed to discourage node misbehaviour. However, these models are
vulnerable to whitewashing attacks. Whitewashing occurs when a node having
poor reputation/trust changes its identity to start afresh and escape from
the consequences of its bad actions. This attack can significantly affect
the performance of reputation based models. We propose a reputation based
scheme for MANETs that acts as a deterrent for whitewashing attacks. Rather
than trying to detect whitewashing attacks, we approach the problem in a
novel way by removing the advantages that whitewashing can provide. In our
proposed scheme, each node must pay an entry fee to consume network
services. As monetary fees are not suitable for MANETs due to fee
management complications, instead of a monetary fee we use a fee in the
form of cooperation. A node will receive services from the network after it
cooperates until its reputation is increased to a certain level Y. For a
normal selfish node, it is no longer beneficial to perform a whitewash
because it will be required to pay the entry fee each time it enters into
the network. Simulation results show that our scheme performs well in
reducing evil throughput as compared to the CONFIDANT scheme in the
presence of whitewashing nodes."

software layer for Desktop Grid resources management. The grid middleware
under concern is named PastryGrid. Its main design principle is to
eliminate the need for a centralized server, therefore to remove the single
point of failure and bottleneck of existing Desktop Grids. PastryGrid
(based on Pastry) supports the execution of distributed application with
precedence between tasks in a decentralized way. Indeed, each node can play
alternatively the role of client or server. Our main contribution is to
propose a fault tolerant mechanism for PastryGrid middleware. Since the
management of PastryGrid is distributed over the participants without
central manager, its control becomes a challenging problem, especially when
dealing with faults. The experimental results on the Grid'5000 testbed
demonstrate that our decentralized fault-tolerant system is robust because
it supports high fault rates."

determined by applying the fixed pre-determined percentage to the annual

raised as to whether the fixed pre-determined percentage is the accurate
measure of market risks. In response to this problem, this paper undertakes
to determine a suitable percentage for the market risks faced by life
insurers in Malaysia. The data involved in this paper are Kuala Lumpur
Composite Index (KLCI), Malaysia Bond Index, foreign exchange rates and
Housing Price Index (HPI) for year 1994 to 2008. A simulation is run to
calculate the volatility of the percentage returns for each index and
foreign exchange rate. Based on the analysis, the percentage of risk charge
for market risks is higher during the crisis as compared to the normal
market condition. As the ups and downs of the market conditions
significantly affect the percentage of risk charge for market risks, it can
be concluded that the fixed pre-determined percentage is not a practical

and variable power adaptation under the constraints of maximum average
transmit power and maximum average interference power allowed at the
primary receiver due to the existence of an interference link between the
secondary transmitter and the primary receiver. We first find the optimal
discrete rates assuming a predetermined partitioning of the signal-to-noise
ratio (SNR) of both the secondary and interference links. We then present
an iterative algorithm for finding a suboptimal partitioning of the SNR of
the interference link assuming a fixed partitioning of the SNR of secondary
link selected for the case where no interference link exists. Our numerical
results show that the average spectral efficiency attained by using the
iterative algorithm is close to that achieved by the computationally
extensive exhaustive search method for the case of Rayleigh fading
channels. In addition, our simulations show that selecting the optimal
partitioning of the SNR of the secondary link assuming no interference link
exists still achieves the maximum average spectral efficiency for the case
where the average interference constraint is considered."

ABSTRACT="In this paper, an improved Maximum Likelihood
Detection (MLD) featuring Log-likelihood (LLR) combining
technique is introduced employing a Low Density Parity Check
(LDPC) cooperative relay scheme. A basic cooperative relay
scheme of a source node (S), multiple relay nodes (R) and a
common destination node (D) is considered. The bit LLR
values are approximated from the symbol LLR which reduces
further the computational burden at the destination. This
scheme employs a low-complexity relaying scheme which
detects the signals (i.e. hard-decision) and forwards (DAF) to
the destination node. While it is known that LDPC codes do not
achieve significant performance gain in Single Input Single
Output (SISO) scheme over block fading channel, we prove
that the gain is significant if Multiple Relay Systems (MRS) is
applied. This improvement is achieved by using only a cheap
DAF relaying protocol which is well-suited for resource limited
conditions, for instance, in sensor networks. The results are
validated through a simulation work and compared with
maximum ratio combiner (MRC) and cooperative-MRC (CMRC)."

ABSTRACT="Paraffins are relatively high molecular weight alkanes which are deposited
as solid (wax) when the temperature drops below the cloud point for the
particular crude oil (hydrocarbon mixture). Paraffin can precipitate from
crude when equilibrium conditions changes slightly causing a loss of
solubility of the paraffin in the crude. Temperature reduction is the most
common cause of paraffin deposition, because paraffin solubility decreases
as the temperature is lowered. Cooling of crude occurs in numerous places
in the well system. Expansion of oil and associated gas at the formation
face, through casing perforation or through a bottom hole screen causes
cooling. Crude moves upward through tubing, surface choke, flow lines, and
through gas oil separators. An experimental and numerical study is proposed
in this paper for predicting the wax appearance temperature (WAT) and
amount of wax formed under different conditions. We will develop a
thermodynamic model in order to calculate the equilibrium between oil and
wax phases during the flow of crude oil. This thermodynamic model will help
to investigate the effect of different parameters and compare the obtained
results with experimental data. A comparison of different activity
coefficients will be presented in order to get the best results by using
appropriate activity coefficient model for the description of solid and
liquid phases in the thermodynamic model of wax precipitation. Experimental
measurements examining wax deposition proposed in this study, including
determination of the wax appearance temperature (WAT), measuring the amount
of wax precipitated under varying temperature and pressure conditions,
viscosity measurements to identify the wax crystallization and
agglomeration We expect that the results of this study will help in
designing an accurate system for production from reservoirs containing
paraffinic oil, in order to avoid or eliminate the phenomenon of wax
deposition"

ABSTRACT="Recovery from some depleting Sudanese oil fields using Enhanced Recovery
methods needs to be studied. Improved/Enhanced recovery techniques may
represent a potential to recover some of the oil left in place. One of
these technologies is polymer flooding to increase the viscosity of the
displacing water when compared to the viscosity of the displaced oil and
consequently improve the displacement efficiency. This paper investigates
different parameters that affect guar gum for potential use in Enhanced Oil
Recovery Processes. Guar gum is as an abundant and environmentally safe
chemical which can be utilized for increasing viscosity of injected water
to improve the recovery of crude oil in certain oil fields. Rheological
study was performed in the petroleum Engineering laboratory for indigenous
guar gum. Effects of concentration, salinity, thermal and biological
degradation factors were thoroughly studied. For four different salinity
waters, the viscosity of polymer in different salinity levels (encountered
in field) was found to increase gradually in direct proportion with
concentration and decreases with salinity. The critical micelle
concentration, CMC (the concentration beyond which no remarkable change in
viscosity is likely) of guar gum was found to be 0.6\%. Bacterial growth is
found to affect guar gum viscosity drastically, however, the effect of
mechanical (shear) degradation as well as thermal degradation (temperatures
up to 100 deg C) was found to be minimal. Based on these results, guar gum
can be a good candidate for use in Sudanese oil fields, however further
coreflood is required to quantify its performance."

ABSTRACT="Continuous or frequent determination of glucose concentrations in diabetic
patients is important for diabetes management. The standard methods for the
measurements are till now invasive and have a lot of shortcomings like
requiring the repetitive lancing and finger bleeding, which accompanied
with pain and risk of infection. A non-invasive detection technique avoids
these disadvantages and has the utility for increasing the frequency of
testing, which enables a tighter control of the glucose concentration, and
hence the potential for a closed-loop system comprising of a monitor and an
insulin pump. Consequently the complications of hyperglycaemia that may
produce organ damages can be avoided. Infrared spectroscopy is a promising
technique and has the advantages that it can be easily applied conveniently
in home monitoring. Applying different light sources having different
wavelengths and using photodiodes and thermopiles as detectors we obtained
reproducible and high dependency of the detected signals of different
glucose concentrations in DMEM solutions at a constant temperature.
However, small Perturbation can cause great alterations on the signals and
hence demise the measurements. The perturbations have to be eliminated and
the dependency of glucose concentrations from the physiological and
disturbing parameters has to be taken into account."

ABSTRACT="Among all control methods for induction motor drives, Direct Torque Control
(DTC) seems to be particularly interesting being independent of machine
rotor parameters and requiring no speed or position sensors. The DTC scheme
is characterized by the absence of PI regulators, coordinate
transformations, current regulators and PWM signals generators. In spite of
its simplicity, DTC allows a good torque control in steady state and
transient operating conditions to be obtained. However, the presence of
hysterics controllers for flux and torque could determine torque and
current ripple and variable switching frequency operation for the voltage
source inverter. This paper is aimed to analyze DTC principles, and the
problems related to its implementation, especially the torque ripple and
the possible improvements to reduce this torque ripple by using a proposed
fuzzy based duty cycle controller. The effectiveness of the duty ratio
method was verified by simulation using Matlab/Simulink software package.
The results are compared with that of the traditional DTC models."

ABSTRACT="Existing multi-channel data acquisition instruments use a dedicated Analog
to Digital Converter (ADC) per channel or a shared ADC for all channels.
The former is cumbersome and more expensive. The latter requires much
faster ADC with a scheduling technique. The round-robin scheduling
technique is used to evenly split the ADC time across all channels which
limits the number of channels and leads to unnecessary collected data. In
this research, a smart low-cost multi-channel Analog Signal Acquisition and
Processing (ASAP) instrument is proposed, designed and implemented. Two
systems are designed and implemented in order to develop the proposed
instrument. First, the Digital Signal Pre-processing unit and the Frequency
Deviation Monitoring system detect and monitor any change in input
channels' frequencies. Second, the Heterogeneous Maximal Service scheduler
adaptively selects the proper sampling rate for each channel. It minimizes
the required speed of the ADC and it reduces the amount of data being
acquired. Performance evaluation is shown via simulations and FPGA
configuration real-time experiments. The accuracy of the Frequency
Deviation Monitoring system reaches more than 99\%. The proposed
Heterogeneous Maximal Service scheduler can schedule cases that are not
schedulable via round-robin. In some cases that round-robin can schedule,
the proposed instrument reduces the amount of data being acquired by 59\%,
which in turn decreases memory requirements and power consumption."

ABSTRACT="Analogous to the beneficial impact that (limited) mobility has on the

O(n) static nodes and O(m) mobile nodes, where each multicast source in the
network has O(d) destinations associated with it. The paper shows that, if
there are sufficient number of mobile nodes in the network, then mobile
nodes can enhance the order behavior of network throughput with number of
nodes $n$.
The paper analyzes a static-mobile hybrid multicast network for an
unrestricted (uniform) mobility model and an all-mobile multicast network
for a class of restricted mobility models. It is shown that, even when
mobility is limited geographically or to some nodes in the network, it can
impact the scaling law of throughput in the network."

ABSTRACT="Session Initiation Protocol (SIP) servers can
experience prolonged overload due to high rates of
incoming service requests or partial network failures. SIP
servers need to be equipped with some form of adaptive
overload detection and control, in order to protect against
high and unpredictable levels of demand and to keep
response times low enough during processing overload to
preclude customers abandoning their service requests
prematurely. Many SIP servers have internal (local)
overload control mechanism, where the overload servers
reject enough new INVITE requests to maximize successful
completion of admitted sessions. However such mechanisms
can only protect the SIP servers against overload to a limited
extent, and it cannot prevent congestion collapse. In this
paper, we introduce Signal-Based Overload Control, SBOC,
which does not require changes in the SIP protocol, as it is
implemented at the sending (upstream) servers,
consequently it does not impose processing burden on
overloaded servers. Extensive simulations show that SBOC
maximizes the goodput of the SIP network, and adapts
appropriately under realistic overload profile."

ABSTRACT={A significant amount of research in the area of freeway traffic management
has been aimed at congestion caused by incidents through their early
detection. Automatic incident detection algorithms rely on data available
from traffic surveillance apparatus (e.g., loop detectors). Incident
detection models are developed based on post-incident traffic data for
historical incidents. The aim is to identify incident conditions from
free-flow and/or recurring congestion. However, increase in mobile phone
usage and video surveillance technology has diminished the relevance of
loop data based incident detection models (FHWA, 2000). Incident detection
is essentially a reactive approach and does not attempt to avoid primary
incidents. To reduce the risk of primary incidents traffic management
authorities may prefer a proactive approach to traffic management. A
proactive approach would essentially involve identifying freeway locations
where a crash is more likely to occur in real-time instead of trying to
assess where the incident has occurred. The approach required for
developing real-time crash risk assessment models is to analyze historical
crashes and traffic surveillance data corresponding to historical crashes
and detect patterns that are often repeated before the crash occurrence. If
these patterns are repeated in the future on a freeway section, that
section may be identified as a real-time {"}black-spot{"} with high
likelihood of crash occurrence. While the infrastructure used by automatic
incident detection algorithms may be used by for implementing the crash
risk estimation framework; there are some critical differences in the way
results are approached. The objective of this research is to identify
conditions under which, based on historical data, the drivers are more
likely to make errors, which in turn lead to crashes. Also, false alarms
are not as detrimental to the present application as they would be for
incident detection algorithms. In fact, the ultimate goal of this research
would, or at least should be, to ‘achieve’ a ‘false alarm’ every
time a crash warning is issued. The goal would be based on the expectation
that with some form of proactive real-time countermeasure or warnings to
the motorists, potential crashes may be avoided. Such countermeasures are
obviously a matter of further investigation but even without the
countermeasures it is neither improbable nor unacceptable to have these
‘false alarms’. Crash prone traffic conditions identified by the
framework proposed here would not always result in crash occurrence even
though a significant proportion of historical crashes did occur under those
conditions. These conditions are worth warning the drivers. In other words,
drivers need to be more attentive under such traffic conditions even if
they do not culminate in a crash every time. The justification or
inevitability of false alarms does not mean that an unlimited number of
warnings could be issued; especially if the information based on the
framework is being transferred to the motorists. It should be ensured that
the drivers do not perceive the warnings to be {"}too many{"} and become
immune to them. Examination of drivers’ reaction to real-time information
about crash prone conditions would be an interesting avenue for future
research. It is also worth mentioning that some of the more recent studies
by the authors have demonstrated significant benefits of using Intelligent
Transportation Systems (ITS) strategies in a simulation environment to
reduce the real-time crash likelihood (e.g., Abdel-Aty et al., 2006). The
ITS measures include Variable Speed Limits and Ramp Metering, and help to
reduce crash risk along the freeway mainline. Microscopic simulation tool
PARAMICS was used to evaluate these strategies. By simulating their effects
using PARAMICS, various strategies were tested to estimate the improvement
over the simulated base case (with no VSL and/or Ramp metering). Ramp
metering and/or VSL strategies currently deployed in metropolitan areas
around the USA primarily aim at reducing congestion or responding to a
weather event. The strategies proposed by Abdel-Aty et al. (2006)
specifically aim at reducing crash risk in real-time as estimated by the
proactive framework discussed in this study. The results obtained by these
studies need to be integrated with the traffic management centers’
existing strategies dealing with congestion.}

ABSTRACT="In this paper, we present a new framework for
combining complete and incomplete methods in order to deal with
The Max Sat problem. Our aim to find the best assignment for a set
of Boolean variables that gives the maximum of verified clauses in
a Boolean formula. Unfortunately, this problem was shown to be
NP-complete if the number of variable per clause is higher than 3.
Our approach called QGADPLL is based on a basic core defined by
a suitable quantum representation and an adapted genetic
algorithm leading to an efficient hybrid framework which achieves
better balance between exploration and exploitation capabilities of
the search process. To foster the process, a local search has been
used. The local search is based on the well known exact algorithm
DPLL. Results demonstrate the feasibility and effectiveness of
this approach"

ABSTRACT={Small and medium-sized enterprises (SMEs) play an increasingly important
role in developing countries including Egypt. In Egypt, SMEs play an
important role in absorbing the labor force especially the youth labor
force. It is very important for economic growth and job creation in Egypt
to support SMEs and enhance their competitiveness. ICT is essential for
enterprise growth and competitiveness. This is especially true for SMEs.
Thus it is important to investigate the use of ICT in SMEs and to identify
the main obstacles hindering access to and the use of ICT. This analysis is
necessary to determine policy interventions needed to promote use of ICT
among enterprises in Egypt, especially among SMEs.
Hence, this study has three main objectives. The first objective of the
study is to analyze differences in ICT use among enterprises in Egypt. The
study compares ICT use among different types of enterprises focusing on
SMEs .The second objective is to evaluate the severity of {"}lack of access
to ICT{"} as an obstacle to enterprise growth and operation in Egypt and
compare the burden of this constraint among small, medium and large
enterprises. The third objective is to analyze the main factors affecting
SMEs access to and use of ICT in Egypt. The study compares SMEs working in
the formal sector with those in the informal sector.
The study uses data from the Productivity and Investment Climate - Private
Enterprise Survey 2008. This survey provides data on different types of
enterprises of different sizes, working in Egypt in the manufacturing and
the service sectors.
Using data from the Productivity and Investment Climate - Private
Enterprise Survey 2008, the study constructed a composite index to measure
intensity of using ICT in different types of enterprises and estimated
costs of ICT use as a percentage of the enterprise total costs, to evaluate
differences in ICT use among different types of enterprises in Egypt.
Another composed index was constructed to measure the severity of {"}lack
of access to ICT{"} as an obstacle to enterprise growth and operation in
Egypt.}

ABSTRACT="Getting products to customers faster and more reliably than competitors is
now seen as a requirement rather than a competitive advantage. Many factors
in today’s business environment have turned management focus into supply
chain management, which is mainly about the integration between the
different business functions. Achieving a level of integration that will
yield new benefits requires that the production and distribution decisions
be made in an integrated and optimized framework. In this paper a proposed
Mixed Integer Programming (MIP), integrated multi-commodity production and
distribution planning model has been developed. The objective of this model
is to produce an optimum integrated production and distribution plan. The
model considers the number of products to be produced in a single plant in
the different planning periods. It takes into account the production
capacity, the vehicles capacity the demand of each product, and the total
costs associated with production, inventory, and transportation. The model
was tested and verified with reference to a benchmark case. LINGO®
optimization package was used successfully in implementing and solving the
model. The model is intended to improve the decision making process in
terms of quality and speed of decision making."

ABSTRACT="Spectrum sensing is one of the most challenging tasks required of a

spectrum sensing, where it is required to perform the sensing as fast as
possible and with an acceptable performance under different channel
conditions. The target signal to be sensed is a Long Term Evolution (LTE)
signal. We first propose sensing the whole LTE signal bandwidth using the
Fast Wavelet Transform (FWT) algorithm and then compare it to the Fast
Fourier Transform (FFT)-based algorithm in terms of complexity and
performance. A new algorithm is proposed that provides an intelligent
stopping criterion for the FWT sensing to further reduce its complexity.
This algorithm shows a major advantage for using FWT. We also propose a
novel algorithm to go even deeper in the LTE signal band to sense at
multiples of a Resource Block (RB) resolution and explain the challenges
associated with the proposed algorithm."

users and satisfying the base station maximum power constraint. We define a
continuous component of the problem, referred to as the site placement
problem, and an integer component, referred to as the site selection
problem. The continuous component involves finding the optimal BS locations
given a fixed number of BSs in the area of interest. We model the
continuous problem as a constrained optimization problem with the BS
locations as decision variables and the powers allocated to their assigned
users as state variables, and we propose and implement an algorithm using
pattern search techniques. On the other hand, the integer component is a
combinatorial optimization problem which involves finding the minimum
number of BSs given fixed candidate BS locations to satisfy the SIR
constraints. We devise an efficient algorithm based on successive
elimination of BSs in order to obtain a minimal BS set. Finally,
experimental results are presented for different scenarios and different

towards congestion to make it use the most available bandwidth while
preserving a logical level of fairness towards other protocols. This paper
aims at evaluating and comparing the performance of the most recent TCP
implementations deployed in popular Operating Systems. We carefully choose
scenarios to investigate the goodput, intra- and inter-protocol fairness of
these TCP variants.  Results show that running Cubic over wired links
outperforms Compound and New Reno in the presence of reverse traffic. 
However, the protocols behave differently over wireless links where they
achieve a low goodput with a very small variation.  Also, all three
variants are fair to other TCP traffic and achieve the same intra-protocol
fairness over wireless links."

function is proposed presenting minimizing problem and the constraints of

ABSTRACT="Digital compensation of nonlinear distortion due to nonlinear

(DLAs) for predistortion of nonlinear systems described using Volterra
series. The adaptive predistorter - which is connected in tandem with the
nonlinear system - can be modeled as a Volterra filter or using linear and
nonlinear FIR filters. Also, the coefficients of the adaptive predistorter
are estimated in this paper using two approaches. The first approach is
based on the Nonlinear Filtered-x Least Mean Squares (NFxLMS) algorithm.
The second approach is based on using the Spectral Magnitude Matching (SMM)
method that minimizes the sum squared error between spectral magnitudes of
output signal of the nonlinear system and desired signal. The coefficients
of the predistorter in this case are estimated recursively using the
generalized Newton iterative algorithm. A comparative simulation study
between these different architectures and approaches is given in this

of the nodes which would cause their encounters and hence the relay of
information from one node to another as well as on the routing protocol
that is deployed. There exists several mobility patterns, each yielding a
different performance of the network. We have shown in a companion work [1]
that the Manhattan mobility pattern performs worse than other widely-used
ones, such as Random WayPoint. Our aim in this work is to propose and
evaluate a new proposal, based on the deployment of fixed relays, so as to

approach is used to simulate the behaviour of some thermo physical
parameters of the solar-still and the temperature difference between the
evaporation surface and that of the condensation and their change in time
as well as their effects on the system performance during the sun shining
period. The mathematical resolution of the system allows describing
energetic balance of each component of the solar still, leading to the
following conclusions (observations): - The daily production of distilled
water increases with the wind velocity till reaching a critical value of 10
m/s, and where this production reaches then its maximum. - Hourly and daily
production increase with the inclination angle of the collector. An angle
of 10° enhances the evaporation-condensation phenomenon and allowing to
obtain better production. - A large temperature difference between the
glass and the water surface improves the daily production; this is related
to the increase in solar radiation during the day. - The system gives
higher production and higher efficiency for lower values of water depths. -
A solar still with a double slope allows collecting a maximum solar
radiation, leading to increase the system performance (production). -
Finally, the optimisation of some thermo physical parameters as well as the
conception of the system allows defining the main and important factors and
parameters that contribute to improve the performance of the system."

apply this adaptive CAC to the case of video traffics using measurements
done by the BS to guess and classify flows according to the similarities in
their behaviours and then adapt the system model parameters that will be
used by the CAC. In this purpose we use a Markovian model adapted for each

ABSTRACT="In sparse mobile networks, nodes are connected at discrete periods of time.
This disconnection may last for long periods in urban and rural areas. In
addition, mobile nodes are energy and buffer sensitive, such as in mobile
sensor networks. The limited power and storage resources, combined with the
intermittent connection have created a challenging environment for
inter-node networking. This type of networks is often referred to as Delay
Tolerant networks (DTN). Routing protocols developed for DTN focused mainly
on maximizing the delivery ratio and minimizing the end-to-end delay.
Therefore, they tend to spread many copies of the same packet into the
network, assuming the availability of buffer and power. Decreasing number
of transmissions reduces energy consumption which helps in maintaining a
clean environment. In this paper, we formulate a mathematical model for
optimal routing in DTN to achieve minimum number of transmissions. In
addition, we study and analyze the DTN heuristic routing protocols. After
that, we propose an Eco-friendly routing protocol, EFR-DTN, that
efficiently use simple information provided from the network to achieve
minimum energy consumption, while maintaining higher delivery ratio than
the other protocols. Simulation results show the outperformance of the
proposed protocol under different buffer capacities, traffic loads, and
packet TTL values."

Our proposed scalar multiplication algorithm based on W2CASC algorithm has
proceeded by 12.7\% to 28\% 160 bit multiplier over similar techniques.

ABSTRACT="The liver is a common site for the occurrence of tumors. Automatic hepatic
lesion segmentation is a crucial step for diagnosis and surgery planning.
This paper presents a new fully automatic technique to segment the tumors
in liver structure with no interaction from user. Contrast enhancement is
applied to the slices of segmented liver, then adding each image to itself
to have a white image with some pepper noise and tumors as dark gray spots.
After applying Gaussian smoothing, Isodata is used to threshold the tumor
in the slice. In order to eliminate erroneous segmentation a discriminative
rule based on diagnostic knowledge on liver cancer shape is applied.
Finally, a 3-D consistency check is performed based on three-dimensional
information that a lesion mass cannot appear in a single slice
independently. Tests are performed on abdominal datasets showing promising
result. Using MICCAI 2008 segmentation evaluation metrics, the novel
proposed technique achieved 80.19 as a total score."

ABSTRACT="In ant colony optimization methods, the central pheromone trails data
structure $\tau$ can be thought of representing the current collective
wisdom of the population. In each iteration, after each ant generates its
candidate solution based on $\tau$ along with a problem-dependent heuristic
function $\eta$, the $\tau$ array is then updated to integrate the
experience gained from the solutions constructed into the collective wisdom
of the group. First, each entry of the $\tau$ data structure is multiplied
by $(1-\rho)$, where $\rho<1$ is an evaporation rate constant (e.g.
$\rho\approx 0.2$), and then some entries of $\tau$ are reinforced based on
the solutions constructed during the current iteration. We propose a
variation in which instead of $\rho$ being constant, each entry of $\tau$
is multiplied by $(1-{\cal N}(\rho\_{m},\rho\_s)))$, where
$N(\rho\_m,\rho\_s)$ is a Gaussian random number with mean $\rho\_m$ (e.g.
$\rho\_m\approx 0.2$) and standard deviation $\rho\_s$ (e.g.
$\rho\_s\approx 0.02$). We evaluate our proposed variation in the context

absorption policy changed dynamically to adapt the radius and angle of
colonies movement towards imperialist's position. Learning automata takes
the role of configuring the movement of colony and creating a balance

ABSTRACT="Vehicles in the near future will be equipped with Dedicated Short Range
Communication (DSRC or IEEE 802.11p) devices to form Vehicular Ad hoc

models of Mobile Ad hoc Networks (MANET) due to their high speed, mobility
constraints and drivers behavior. Most researches on analyzing the
performance of IEEE 802.11p done without taking into account vehicles' high
dynamics assuming stationary distribution of vehicles on the road. They
assume that all vehicles within the range of the transmitter will receive
the transmitted packet successfully while vehicles near the outer edge of
the communication range of the transmitter are more vulnerable to cross the
boundary before they receive the packet completely. They also used Most
Forward Within Range (MFR) \cite{MFR} to forward the message from one hop
to the next. In this paper, we develop a new mobility model to derive the
number of vehicles on the road and the probability of receiving the
broadcasted packets successfully from all vehicles within the communication
range of the transmitter. We also derive the probability of multi hop
connectivity taking into account the location of relay vehicles and proved
that MFR is not a valid scheme for VANETs."

The output of the PMSG is connected to a single switch three-phase boost
rectifier to generate DC voltage which feeds a current controlled inverter
to interface the system with the electric utility. The single switch
three-phase boost rectifier is an active power factor correction technique
to maintain the power factor at the PMSG side to nearly unity and mitigate
the PMSG current harmonic. To mitigate inverter output current and voltage
harmonics, an LCL filter has been used. A complete analysis of the harmonic
content has been done everywhere in the system. The results show that the
proposed MPPT control strategy succeeded to track the maximum wind power
irrespective of the wind speed. This strategy in presence of LCL filter
achieved harmonic mitigation at the PMSG and inverter output sides."

ABSTRACT="Networks in which nodes are intermittently connected, and have limited
buffer space and limited power, are termed Delay Tolerant Networks (DTN).
To overcome these conditions, DTN routing protocols require nodes to store
data packets for long periods of time until they contact with each other.
In addition, they spread multiple copies of the same packet in the network
to increase the probability of one of them reaching the destination.
Long-term storage and multiple transmissions require large buffer space and
non-restricted power availability which is hard to exist in DTN. In this
paper, we study the routing problem in DTN with limited resources. We
formulate a mathematical model for optimal routing, assuming the knowledge
of present and future nodes contact and buffer space. After that, we
analyze the previously developed heuristic protocols, and we propose a new
protocol based on social relations between the nodes to avoid redundant
copying of packets. Simulation results show that the proposed protocol
provides lower network overhead and better delivery ratio compared to other
protocols."

However, proposed method could consider all these necessities together in

significantly. The functionality of the proposed scheme is carried out by
using continual-scattered pilot pattern correlation in time domain. This
concept introduces new facilities
to offer better timing synchronization as well as better carrier frequency
offset estimation. Furthermore, by using the proper properties of this
correlation, the pilot pattern detection will be done in time domain. The

It is shown in the literature that an efficient relay selection protocol

performance at the destination of such networks. Also, a similar analysis
on the optimal power allocation for the source and the relay exists in the

should be accomplished. To this aim, we reformulate the SEP performance at
the destination of a simple cluster-based cooperative WSN in the general
form and solve the mentioned joint optimization problem efficiently for a

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-to-cluster 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."

Sarawak, Malaysia. The field was discovered in 1980 and production started
in May 2002 with subsea wells and the expected recovery factor is only
59\%. With the initially planned maximum offtake production policy, the
field experienced rapid GWC rise and water breakthrough in the development
wells within 4 years of production period. Production data suggests that M4
exhibit a common aquifer with the neighboring fields which is much stronger
than what was expected initially. This paper presents an integrated
subsurface study for better reservoir characterization that leads to
hydrocarbon recovery improvement. The methodology integrates 4D seismic
results in reservoir characterization, monitoring the reservoir
performance, and its application to obtain a better history matching
results and subsequently produces reliable prediction strategy for recovery
factor improvement. The history matching analysis on M4 model was conducted
with high weight placed on matching the water movement and breakthrough
time, water-gas-ratio and pressure distribution. By incorporating the 4D
seismic results, the resulting history matched model is significantly
improved with less degree of uncertainty and it is believed to be much more
reliable to produce optimum prediction strategy which focused on recovery
factor enhancement. Various prediction scenarios together with advanced
modeling of the regional aquifer effect on field pressure have been
examined using the final history matched model. By doing this, the M4
recovery factor is improved by 15\% and thus giving the field the second

ABSTRACT="This paper is the second of a set describing the implementation and
economic analysis of an improved solar photovoltaic (PV) system for
Malaysian rural electrification. The work was carried out based on a case
study in a rural community to replace their diesel‐powered generators
with the new renewable energy solutions, with buffer capacity for
additional requirements. Based in the extensive tests done on the system,
it is proven that the new improved design of solar power system can be
implemented as it meets the technical requirements of the project.
Considering not only the technical requirement, it is also important to
design the implementation and maintenance schedule of the system since the
local communities have no or little exposure to this system. With adequate
trainings and briefings, the maintenance schedules can help them to get
involved in the operation and maintenance of the system. Other than that,
the economic value of a PV system is calculated so that it can be compared
with other methods of power generation. The details of the implementation
of solar power system and its impact to the community are discussed in this
paper."

ABSTRACT="Multicasting is an essential technology in applications like IPTV or online

In this article, we introduce a new performance criterion, called multicast
gain, which can be used for computing multicast efficiency. We analyze
multicast transmission for delivery of live TV channels in tree-based
networks representing e.g., multicast trees, and determine the gain of
subtrees and links in order to quantify the benefits of multicasting. We
also define a threshold in order to identify cases in which unicasting
might be preferable. We show that although multicasting can usually
outperform multiple unicasting in terms of bandwidth usage, due to the
inherent overhead in establishing and maintaining multicast connections, in
special cases, using multiple unicast flows can be a better choice."

ABSTRACT="Emergences of technology had enabled the development of various innovative
teaching-learning tools in education. The enjoyment offered by multimedia
can increase learner's motivation and participation thus allowing them to
retain the learning process in longer period compared to using traditional
classroom method. As slow learners are difficult to maintain their learning
attentions for long time span, multimedia courseware is believed to assist
them. This paper presents the findings from a preliminary analysis of slow
learners conducted in special education schools. In this study, qualitative
methodology using interview with special education teachers and class
observations were conducted to undestrand the slow learner's
teaching-learning situations as a whole. The key findings from the analysis
are the problems with existing ICT application, slow learner's learning
characteristics, interest and behaviour and also the potential that
multimedia courseware can bring in motivating and increasing slow learner's
interest in learning. Several guidelines for designing multimedia
courseware for slow learners are proposed. Conceptual framework is also
being illustrated in this paper as guide in conducting further research.
All these preliminary findings are hope to assist in designing multimedia
courseware and will successfully facilitate the slow learners as well as

ABSTRACT={A typical consumer digital camera uses a Color Filter Array (CFA) to sense
only one color component per image pixel. The original three-color image is
reconstructed by interpolating the missing color components. This
interpolation process (known as demosaicing) corresponds to solving an
underdetermined system of linear equations. In this paper, we show that by
replacing the traditional CFA with a random panchromatic CFA, recent
results in the emerging field of Compressed Sensing (CS) can be used to
solve the demosaicing problem in a novel way. Specifically, during the
image reconstruction process, we exploit the fact that the
multi-dimensional color of each pixel has a compressible representation in
a (possibly overcomplete) color system. While adhering to the {"}single
color per pixel sensing{"} constraint at the sensing stage, during the
reconstruction process we utilize the inter-pixel correlation by exploiting
the compressible representation of the overall image in some sparsifying
bases. Depending on the CFA, sparsifying bases and the color system, we
form an underdetermined system of linear equations and find the sparsest
solution for the color image by utilizing a CS solver. We illustrate that,
for natural images, the proposed CD framework performs better (mostly
significantly better) than leading demosaicing approaches. Furthermore, CD
could achieve virtual perfect reconstruction on most tested images.}

ABSTRACT="We consider the problem of recovering a signal/image (x) with a k-sparse
representation, from hybrid (complex and real), noiseless linear samples
(y) using a mixture of complex-valued sparse and real-valued dense
projections within a single matrix. The proposed Hybrid Compressed Sensing
(HCS)employs the complex-sparse part of the projection matrix to divide the
n-dimensional signal (x) into subsets. In turn, each subset of the signal
is mapped onto a complex sample of the measurement vector (y). Under a
worst-case scenario of such sparsity-induced mapping, when the number of
complex sparse measurements is sufficiently large then this mapping leads
to the isolation of a significant fraction of the k non-zero coefficients
into different complex measurement samples from y. Using a simple property
of complex numbers one can identify the isolated non-zeros of x. After
reducing the effect of the identified non-zero coefficients from the
compressive samples, we utilize the real-valued dense submatrix to form a
full rank system of equations to recover the remaining coefficients. We
show that the proposed hybrid approach can recover a k-sparse signal while
requiring only 3k3√n/2k real measurements.We also derive expressions for
the optimal mix of complex-sparse and real-dense rows within an HCS
projection matrix. Further, in a practical range of sparsity ratio k/n
suitable for images, HCS outperforms even the most complex CS frameworks.
The theoretical complexity of HCS is less than the complexity of solving a
full-rank system of m linear equations. In practice, the complexity can be
lower than this bound."

randomness of vehicle traffic and the statistical variation of the
disrupted communication channel. Our framework employs the effective
bandwidth theory and its dual, the effective capacity concept, in order to
obtain the maximum distance between RSUs that stochastically limits the
worst case packet delivery delay to a certain maximum value. We study the
effect of the vehicle density, transmission range, and speed difference
between vehicles on the end-to-end packet delivery delay. A key finding of
our study is that the packet delivery delay becomes non-sensitive to
limited changes in both vehicle density and transmission range in a sparse
VANET if vehicles are allowed to bypass each other. Extensive simulation
results validate our analytical framework and demonstrate that it is
accurate in calculating the maximum separation distance between adjacent
RSUs that probabilistically limits the worst case delay bound."

industrial importance. However, attaining tight control has remained a
challenge since pH neutralization process exhibits severe static
nonlinearity and time varying characteristics. For these reasons, advanced
control strategies such as model-based control was implemented in this
work. Model-based control is a control system that explicitly embeds a
process model in the control algorithm, thus, a process model is needed in
order to develop the control scheme. Since pH process is a highly nonlinear
process, derivative of mechanistic model is divided into two parts: static
nonlinearity titration curve and dynamic behavior of the reactor. Using a
SSIMM microreactor as reaction chamber, introduces further difficulies due
to fast responsiveness of the miniaturized intensified systems. Thus the
controller performance was staudied for different values of desired
close-loop time constants, λ in selected pH ranges. From the results

ABSTRACT="The increasing popularity of the IEEE 802.11n wireless applications demands
low cost and high quality RF applications in the 5 GHz spectrum region
particularly for RF filters. Simulation performances and low cost
implementations are given the spotlight in many RF filter designs proposed
in the literatures but fail to address the importance of physical
performances which are dependent on design, material of choice, design and
fabrication methodologies and particularly, matching the physical RF feed.
RF filter designs on EM CAD simulation tools are using ideal and perfect RF
feed model provided by the tool libraries. Unfortunately, low cost real
world RF connectors for probing, measuring and interfacing are non-ideal
and imperfect and come in many types and shapes such as SMA, N etc. These
RF connectors have fixed structure and impedance. The imbalance structure
joining between the RF connectors and the design RF feed, even with
matching impedance at both ends, severely affects the overall physical
performance of the design, resulting large mismatched with the simulation
result. This paper presents the rapid modeling, characterization and
optimization methodology to produce high performance RF filter design and
showing the severe effect of imbalance feed structure when joining the
filter feed with RF connectors. This paper also shows how two equal RF
filters using parallel microstrip coupled line design with different feed
structures connecting to RF connectors can have different performance. The
filters are fabricated on Rogers R04350B substrate with dielectric 3.66
using computer numerical control (CNC) machine for rapid design
characterization and optimization to achieve matching impedance at the
joints and performance. High performance filter design with low insertion
loss of 1 dB, return loss of 20 dB and wide operating bandwidth is
achievable with the proposed methodology."

ABSTRACT="Clogging of water intakes caused by accumulation of floating trash is a
common problem experiencing by many run-off-river hydro power plants. Tenom
Pangi Hydro Station is significantly affected by it which leads to
reduction of power generation or sometime station shutdown. A trash
diverter system was developed to prevent the clogging and based on existing
station operational constraints. The development involves mainly a
brainstorming session to finalize the conceptual design, and computer
modeling. Commercial computational fluid dynamic (CFD) program was utilized
to create computer model to analyze and evaluate the river flow
characteristics due to trash diverter installation in order to determine
the trash diverter location for effective diversion of trashes and minimum
flow resistance into the water intakes. Finite Element Analysis (FEA)
program was used to do stress analysis on the trash diverter structure. The
power station requirement, the design of existing water intakes from other
local hydropower and water treatment plants were also considered in finding
the effective solution. The results from the modeling and analysis were
used to establish preventive measures for preventing existing water intakes
clogging and specification for the construction of the trash diverter
system."

ABSTRACT="Orthogonal frequency division multiplexing (OFDM) is a modulation technique
that provides high achievable data rates in wireless environment by
combating multipath effects and has relatively simple implementation. In
this paper, it is demonstrated that how the cyclic prefix can be used to
enhance the operation of an OFDM equalizer when the channel is perfectly
known at the receiver or is obtained through training. This method relies
on transforming the OFDM channel into two subchannels (circular and linear)
that share the same input and are characterized by the same channel
parameters. Conventionally, data is recovered by utilizing only the
circular subchannel while in this method, both the circular and linear
subchannels are used to recover the data. The improved performance of the
proposed method is demonstrated with the help of simulations for constant
modulus as well as non-constant modulus data."

ABSTRACT="This paper investigates a method of detecting and tracking damage in an
offshore platform located in the North Sea under the excitation of typical
sea storm in the North Sea by performing a finite element simulation. A
modal analysis and nodal displacement result from FE simulation are adopted
for analysing the dynamic characteristics of this platform. For this
purpose, the JONSWAP spectrum and Morison equation are applied to simulate
the typical wave force in the North Sea using Matlab and Simulink
programme. The associated mode shape vector obtained in modal analysis was
correlated with the sea force vector which was the forcing function (force
per unit length) to the structure. The determination of the dynamic
response with realization to the real scenario was established by
introducing some reduction of material stiffness in one of the diagonal
member in stages. The results in time-displacement obtained from finite
element simulation were converted into time-acceleration domain before they
were analysed in frequency spectrum using Power Spectrum Density in Matlab.
The frequency analysis showed that there was a significant shift in peak
frequency between the intact and damage structure response with 30\%
stiffness reduction, provided that the sea force applied is in the
direction of the damaged beam member orientation. This suggested that the
shift in the natural frequencies of the dynamic response can provide a
useful tool in monitoring the dynamic response and tracking the progression
of fatigue failure of the structure."

based on the assumption that the transmitted data in an OFDM system is
Gaussian (by central limit arguments). The channel estimate can then be
obtained by maximizing the output likelihood function. Unfortunately, the
likelihood function turns
out to be multi-modal and thus finding the global maxima is challenging. We
rely on spectral factorization and the cyclostationarity of the output to
obtain the correct channel zeros. The Genetic algorithm is then used to
fine tune the obtained solution."

ABSTRACT="Diversified opportunities (possible numerous applications)
and challenges (resource constrained nodes) are contributing
factors behind the extensive research in sensor networks.
Continuous monitoring of the natural phenomenon is one
of the major streams of the possible application in this arena.
Sensing and monitoring of natural phenomenon involve dealing
with correlated data in both spatial and temporal dimension.
Aggregation technique plays a significant role by reducing the
amount of data transmission in wireless sensor networks (WSN)
as correlation is dominating in the real world. This reduction on
the amount of data is vital due to the energy scarcity of the WSN.
This paper presents a simple aggregation technique named smart
aggregation (SAG) for the continuous-monitoring applications in
WSNs. SAG maintains a tolerable deviation i.e. limited error
in the aggregated data while compressing both spatially and
temporarily. We present simulated results that rationalize the
development of the protocol. The comparison is made with k-
hop aggregation and CM-EDR algorithm in terms of energy
efficiency showing the potential improvement gained by applying
our aggregation scheme."

ABSTRACT="To achieve a high compression ratio in coding video data, a method known as
Motion Estimation (ME) is often applied to reduce the temporal redundancy
between successive frames of a video sequence. One of ME techniques, known
as Block Matching Algorithm (BMA), has been widely used in various video
coding standards. In recent years, many of these BMAs have been developed
with similar intention of reducing the computational costs while at the
same time maintaining the video signal quality. In this paper, an algorithm
called Hexagon-Diamond Search (HDS) is proposed for ME where the algorithm
and several fast BMAs, namely Three Step Search (TSS), New Three Step
Search (NTSS), Four Step Search (4SS) as well as Diamond Search (DS), are
first selected to be implemented onto various type of standard test video
sequence using MATLAB before their performances are compared and analyzed
in terms of peak signal-to-noise ratio (PSNR), number of search points
needed as well as their computational complexity. Simulation results
demonstrate that HDS algorithm has speed up other algorithm’s
computational work up to 56\% while at the same time maintains close
performance in terms of PSNR to others."

ABSTRACT="In this paper, we propose a RESTful active proxy, called Tambourine,
towards realizing globalization in network management. Tambourine radically
changes the landscape of traditional closed-domain SNMP monitoring into a
multi-domain, multi-user monitoring activity by translating HTTP requests
from a huge number of Internet users into adequate SNMP requests to network
devices. Implementation of cache in Tambourine is vital to ensure that SNMP
traffic is kept at a minimum level to avoid burdening network devices with
repetitions of SNMP requests. Existing web cache technology however could
not be implemented in Tambourine due to two main reasons (i) SNMP is not a
cache-aware protocol, and (ii) the value for several OIDs, such as system
uptime, changes in real-time causing stale data if it is cached. To solve
these problems, our cache design applies a four-state transition to
determine the optimum TTL for each OID. Tambourine also aggregates multiple
HTTP requests from the same user into a single SNMP request to further
reduce the SNMP traffic. In our experiments where three users used a
modified MRTG to generate HTTP requests to Tambourine, our cache design
converges to zero staleness ratio after five 5-minute cycles."

Moreover, Gaussian dropping is often considered as an effective placement

cross-terms interferences due to their bilinear structures. In this paper,
smooth-windowed Wigner-Ville distribution (SWWVD) is used to analyze power

ABSTRACT="The contextual integration between the water bodies, waterfront and the
city has long been established in history when water used to be the main
transportation mode. The importance of the integration of water bodies to
many cities is globally acknowledged. Over the years, many of these cities
have lost their integration with their water bodies due to many factors
such as the industrial revolution, development in transportation system and
technology. In an attempt to achieve sustainable development, most cities
have attempted to reintegrate the city with the water body even to the
extent of removing highways which had been constructed parallel to the
water body. These expensive approaches are some of the many efforts done
due to the increasing awareness on the benefits gained through waterfront
regeneration. This has, however, helped to secure the sense of place as
well as increasing the quality of living and working environment of the
urban community. The lost of integration between the city and the water
bodies is also experienced by the capital city of Malaysia, Kuala Lumpur.
In the case of Kuala Lumpur city, the Klang and Gombak Rivers that run
through the city centre act as the main water bodies. It used to be the
life lines of the City when it was the main transportation mode for the
people. It was from the rivers and the waterfront area that the
morphological development of the city evolves. There are also attempts to
re-integrate the rivers to the city since 1979. Based on a qualitative
method, this paper employs content analysis and focus interview as the
research tools to evaluate existing policies and guidelines available on
the contextual integration between the waterfront and the urban river. This
paper provides the six main findings which directly contributed to the
existing contextual integration between the waterfront and the water
bodies. These are i) absence of policy and guidelines before the third
morphological period ii) existing policies and guidelines are general and
mostly referring to zones rather than according to plots iii) Policy and
guideline developed and implemented in isolation by different government
agencies iv) lack of guidelines which is suitable to the Kuala Lumpur
waterfront. v) lack of detail master planning for Kuala Lumpur waterfront
vi) guidelines which are not legally bounded are making implementation
difficult. These aspects are important to be underlined so that they are
clearly identified, acknowledged and overcome for a more sustainable
development of the waterfront in the city centre of Kuala Lumpur."

ABSTRACT="Early detection on any abnormality on the pipeline such as leakage is
essential for efficient management. As to date, wireless sensors have been
widely used to gather information in monitoring reliability of the
pipeline. The commonly used sensors are temperature and pressure sensors.
One of the issues that relate to pipeline monitoring is the reactive rather
than proactive maintenance approach to leakage and abnormality. The
objective of this research is to develop a method for early detection of
corrosion, which the buried pipeline is exposed to changing temperatures
and gas flow pressures. This will ensure that maintenance works can be done
quickly to prevent pipe burst, as well as to minimize operational cost. The
NORSOK CO2 corrosion rate model is used as a basic reference model and the
devices that will measure the value of pressure and temperature is wireless

ABSTRACT="Changes in hydrocarbon pressure and saturation due to production produce
noticeable changes in amplitude response. 4D seismic, or the use of
repeated 2D/3D seismic surveys as a function of calendar year, enables
detection of 4D signal indicative of production changes. Determining
pressure-saturation variations involve integrating several geophysical
technologies working in close ties with the reservoir engineers, that is,
supporting petroleum geo-engineering. These technologies include
well-synthetic-seismic correlation, Rock Physics, Production Scenario
Seismic Modeling at selected injector/producer wells, 2D/3D seismic
modeling, 4D AVO Modelling/Interpretation and correlating seismic
attributes with the engineering data, pressure history and saturation
measurements.

We are primarily motivated by previous work (Landro, 2001) which focuses on
the use of 4D AVO data to decouple pressure and saturation variations,
taking note that AVO attributes of Intercept and Gradient may not be
suitable, as they conflict with the small angle assumption in the data. We
should study and use the seismic attributes which respond differently to
reservoir changes in pressure and saturation.

Rock physics representation in a production field may indicate oil response
separation from the background. An AVO modeling study can be conducted to
understand and compare the predicted AVO responses at the reservoir sands
with the response observed on the base-monitor seismic data. A seismic
section passing through a channel sand is correlated with the corresponding
seismic channel model for a structural image analysis generated using
actual acquisition parameters from any given production field. Seismic
attributes and difference maps can then be correlated and integrated with
pressure and saturation maps for interpretation of the 4D effects.

Improving reservoir monitoring through the effective use of 4D Seismic
Pressure-Saturation discrimination methods will enable us to more
accurately locate bypassed oil and therefore, increase reserves. In
addition, 4D seismic will minimize costs due to infill drilling by
optimally locating development wells."

ABSTRACT="Defect free perovskite-dispersed titania (perovskite-titania) membrane had
successfully prepared by sol-gel method combined with wet impregnation
process. In this experiment, titania membrane was immersed in perovskite
solution, dried and calcined to obtain perovskite dispersed in titania
membrane. The phase composition and membrane morphology of the membrane
were characterized by TGA, XRD, TEM and SEM. TEM result demonstrated that
the perovskite particles were well-dispersed among the titania particles.
SEM analysis showed that uniform thickness of the membrane on titania
support approximately 0.5 µm was obtained after multiple coatings and
calcined at 400 ⁰C. The produced titania disc supported crack-free
perovskite-titania membrane may be promising for gas separation

Segmentation of Magnetic Resonance Imaging (MRI) images is an important
part of brain imaging research. In this paper, we used controlled
experimental data as our testing data. The data is designed in such a way
that prior knowledge of the size of the abnormalities are known. This is
done by cutting various shapes and sizes of various abnormalities and
pasting it onto normal brain tissues, where the tissues and the background
are divided into different categories. The segmentation was done with
twenty data of each category. The knowledge of the size of the
abnormalities by the number of pixels were then used as the ground truth to
compare with the SBRG segmentation results. The proposed SBRG technique was

maintenance for high performance regardless of whether it meets the

Defect analysis is significance if universities desire to succeed in
modeling an efficient maintenance management system for their buildings and
engineering services. This paper is part of an ongoing research on the
development of systemic maintenance management for university buildings in
Malaysia. The aim of this paper is to determine, evaluate and categorize
defects in the university buildings in Malaysia. Questionnaires were
administered on 50 university maintenance organizations. With a 66\%
response rate, the findings suggest that some defects require maintenance
urgently than the others and on the basis of which it is concluded that
resources should be directed to the more urgent ones while less urgent ones
could be included in the subsequent maintenance prgramme. The research
found that lift failure, faulty electrical systems and roof damages were
the defects that respondents considered extremely urgent to maintain. The
paper concludes by arguing that maintenance management is a strategic issue

ABSTRACT="The key to surgical planning for breast conservation is tumor localization.
An accurate localization of the breast tumor is essential to guide the
surgeon to the lesion, and ensure its correct and adequate removal with
satisfactory excision margins. Current breast tumor localization techniques
are invasive and often result in a cosmetic disfigurement. In this paper,
we use the ultrawide band radar-based microwave breast imaging technique to
non-invasively localize (impalpable) tumors in the breast. We consider four
clinically important lesion features: location, size, depth and spatial
orientation within the breast. A comparison of the energy of the received
signal from healthy and cancerous breasts exhibits some remarkable
differences in some frequency bands. We, therefore, use the energy spectrum
of the receiving antenna signal decomposed by wavelet transform as the
input to a genetic neural network (GNN) classifier. Furthermore, for
improved efficiency, we optimize the structure of the GNN for optimum
initial weights and number of hidden nodes. We use CST Microwave Studio to
simulate benign and malignant breast conditions, and generate a data set of
1024 cancer cases with various tumor location, size, depth and spatial
orientation within the breast. Our results show that the proposed algorithm
gives accurate localization of the breast lesion, and possesses a high
sensitivity to small tumor sizes. Additionally, it can accurately detect
and classify multiple tumors."

ABSTRACT="Radio Frequency Identification (RFID) tags possess the ability to uniquely
identify every individual item at low cost. This emerging RF technology is
well suited for supply chain management and is expected to replace barcodes
in the near future. However, unlike barcodes, these tags have an extended
range in which they are allowed to be queried by a reader. This may result
in different attack scenarios such as unauthorized scanning by malicious
readers Therefore, a security protocol for RFID enabled supply chain is
necessary to ensure the privacy and authentication between each tag, the
corresponding reader and the backend server . In order to counter the
evolving security issues, we propose a secure RFID based architecture for
supply chain hierarchy. This architecture comprises of four different
phases depicting the movement of a tagged item from source to destination.
There are four different protocols supporting this architecture. Although
this architecture was designed for use in supply chains, it can also be
used for other RFID enabled applications by incurring minute changes."

of two versions. The first version is a basic composite neighbourhood

the second version, the neighbourhood structure is selected based on an
intelligent selection that is controlled by some rules (coded as IS-CNS).
In both of the cases, the algorithm only accepts an improved solution. The

ABSTRACT="Network reconfiguration in distribution system is realized by changing the
status of sectionalizing switches, and is usually done for the purpose of
loss reduction. Loss reduction can result in substantial benefits for a
utility. Other benefits from loss reduction include increased system
capacity, and possible deferment or elimination of capital expenditures for
system improvements and expansion. There is also improved voltage
regulation as a result of reducing feeder voltage drop. Research work
included by this paper focuses on using branch exchange method to minimize
losses and solve the problems over different radial configuration.
Solution's algorithm for loss minimization has been developed based on two
stages of solution methodology. The first stage determines maximum
loss-reduction loop by comparing the size of circles for every loop. In a
distribution system, a loop is associated by a tie-line and hence there are
several loops in the system. To obtain the maximum loss reduction loop,
size of modified zero loss-change circles are compared, and the loop within
the largest circle is identified for maximum loss-reduction. The second
stage determines the switching operation to be executed in that loop to
reach a minimum loss network configuration by comparing the size of the
loop circle for each branch-exchange. The smallest circle is to be
identified for the best solution; the size of the loop circle is reduced
when the losses are minimized. The performance of the proposed branch
exchange method is tested on 16-bus distribution systems."

ABSTRACT="The increment of power demand can cause a rapid reduction in voltage
profile that can disrupt system stability leading to potential failure on
the entire system as the system has to work under a stressed condition.
Thus, the Flexible AC Transmission System (FACTS) are integrated in power
system to control the power flow in specific lines and improve the security
of transmission line. This paper proposes a static voltage stability index
(SVSI) for placement of Thyristor Controlled Series Compensator (TCSC) and
used Evolutionary Programming (EP) techniques for optimal sizing of TCSC
used for system under contingencies. The objective of the study is to
minimize the total real power losses, and at the same time monitoring the
voltage profile along with the installation cost. Critical contingency
cases have been used to decide optimal sizing for the placement of TCSC.
The TCSC devices are installed in the system in order to enhance the system
security; performed on the IEEE 30-bus RTS for several loading conditions.
The simulations results are compared with those obtained from the
Artificial Immune System (AIS) technique in the attempt to highlight its
merit."

ABSTRACT="This paper concerns with transient stability control which is part of
transient stability assessment which needs to be considered so that the
power systems remained intact when failures originating from faults
occurred in power systems. Conventional UFLS system is designed to retrieve
the balance of generation and consumption following disturbances
occurrences in the system. In UFLS method, whenever the system's frequency
drops below a predetermined value, the system loads are shed in stages. An
efficient UFLS method needs to be devised so as to reduce the impacts of
transient disturbance on power systems and prevent total system blackout.
In this paper, an emergency control scheme known as the combined UFLS and
generator tripping is developed in order to stabilize the system when
unstable faults occurred in a power system. The performance of the combined
UFLS and generator tripping scheme is compared with the conventional UFLS
control scheme. The results show that the combined control scheme performed
better."

ABSTRACT="The study of gunshot residue (GSR) has become imperative in forensic
firearm examination. It may be used to estimate firing distance, to
identify bullet holes and to determine whether or not a person has
discharged a firearm. This study emphasized on the examination of the
pattern of GSR particles deposited on cotton cloth target at different
shooting distances (3 inch-12 inch). Two types of pistol (semiautomatic and
revolver) and ammunitions (Syarikat Malaysia Explosive (SME) and
Winchester) were used for the shooting test. All shooting tests were
performed at Lapang Sasar of Pasukan Gerakan Am PDRM, Cheras. The results
showed that GSR particles produced on cotton cloth by semiautomatic pistol
using SME 9 mm ammunition generated higher amount and larger GSR particles
which were almost completely burnt particles. The nitrite residues were
confirmed by using modified Griess test that revealed semiautomatic pistol
produced considerable amount of nitrite residues. Scanning Electron
Microscope (SEM) micrograph of GSR particles discharged from semiautomatic
pistol using SME 9 mm ammunition revealed a mean particle size of 2.6 µm
with spherical shapes. On the other hand, by using revolver pistol with SME
0.38 Special ammunition, the GSR particles produced were small in amount.
The modified Griess test also revealed that revolver pistol generated tiny
amount of nitrite residues. Nevertheless, by using Winchester 0.38 Special
ammunition, the GSR particles discharge were of high amount and large in
size which composed of completely unburned, partially burnt and completely
burnt particles. Whereas SEM micrograph of GSR particles discharged from
revolver pistol using Winchester 0.38 Special ammunition generated
irregular cluster grain with a mean diameter of 3.3 µm. Sodium rhodizonate
test was successfully applied for detecting the presence of lead residues
around the bullet hole for both pistols."

ABSTRACT="Rattan is one of the most important non-timber forest products after timber
that has been used in many applications. Rattan is belonging to the family
Arecaceae or Palmae and subfamily Calamoideae. While Malaysia is known to
have abundant resources of rattan, there is no comprehensive publication
available on the distribution patterns, species abundance and species
composition of rattan, especially in the protected forest areas of the
country. Information such as these is useful to complement the conservation
efforts, while enhancing knowledge on its diversity in the natural
habitats. The objectives of this study are to determine the species
distribution, abundance and diversity of rattan in the natural population
of Kuala Keniam forests in Taman Negara Pahang. The species abundance,
composition and distribution of rattan were determined in three established
100m × 20m transects. All rattans were tagged and the variables such as
the diameter, stem length, number of culms and habit of rattan were
recorded. A total of 69 rattan plants were found in the three transects
studied. Three species with highest species richness are Calamus lumidus
(Rotan kerai), Calamus caecius (Rotan sega) and Daemonorops didymorphylla
(Rotan jernang). In Kuala Keniam forest, rattans are found to be highly
distributed at the diameter class of 10mm 15mm. In terms its abundance,
it was estimated that there are 115 number of rattan clumps per ha and 520
number of rattan culms per ha are available in this area. Information from
this study provides baseline information on the distribution, population
structure and density and perhaps an informed basis for in situ
conservation and management of this resource."

ABSTRACT="Generating an initial solution and then iteratively improve the solution
are common initial steps in solving class scheduling problems. In this
improvement process, the re-assignment of events to a new time slot and the
selection of event to be reassigned play a significant role in reducing the
soft constraint violation and finally improving the quality of the
timetable. This paper proposes a local search heuristic which handle an
event selection namely Event Selection based on Soft Constraint Violation
(ESSCV) applied in a modified PSO algorithm to solve class scheduling
problems. This technique was based on the idea of re-assignment of event
which contributes to soft constraints violation, hoping the new assignment
will alleviate the violation. The performance of the proposed technique was
measured based on percentage penalty reduction (\%PR) and execution time.
Five sets of data from International Timetabling Competition were used in
the experiment. The experimental results shows that ESSCV managed to reduce
the event contributed to soft constraint violation, thus increases the \%PR
even though also demonstrated a small increase in execution time."

The Fuzzy logic controller to control the camera panel angles of light
tracking system is designed. Two fuzzy controllers are proposed, one for
each motor to produce proper PWM in order to track the light source. A
typical FLC includes three basic components, an input signal fuzzification,
a fuzzy engine, and an output signal defuzzification. The Fuzzy controller
input parameters (Xcp,Ycp) and variation of duty cycle output parameters
are used to generate the optimal pulse-width- modulated (PWM) to track the
light source, such that PWM is generated under different operating
conditions to drive the motors. The motors will react accordingly when they
receive signal from the sound card to make sure the camera always focuses
on the centroid of the light source. The system tested at different
locations. The data which were obtained by experiment were able to show a

aware routing algorithms fail to resolve the hotspot problem, which is the
isolation of the sink node due to the power exhaustion of the nodes that
are close to the sink node. In this paper, we propose a solution, referred
to as HYbrid Multi-hop routiNg (HYMN), to address this issue by combing two
routing strategies, flat multi-hop routing and hierarchical multi-hop
routing. The former method aims at minimizing the total power consumption
in the network; the latter attempts to decrease the amount of transferred

that produce voltage response indicative of ionic concentration change.
However, in the presence of ions of similar charge, the voltage levels tend
to be influenced by the interfering ions. The training dataset is based on
actual measured data and are collected from dc response of sensors from
titration. The multiple classifier system consists of feedforward
multilayer perceptron weak learners constructed by bagging algorithm.
Diversity is achieved by randomness of free parameters and resampling
techniques of datasets by bootstrapping. Results demonstrate that multiple

for communication between people as machine can also be involved in IM
conversation. The software known as IM bot is currently being used to
provide user with weather, stock exchange and local news. Using the same
concept, an IM bot is being developed to provide system administrator with
remote machine status and information. The tool detects the machine
presence on the IM network thus allowing system administrator to interact
with them. Furthermore, IM messages and presence information is used to
relay system status and information to the system administrator. With the
real-time nature of IM, this tool can benefit system administrator with
real-time system status and notification messages. In addition, the contact

highly populated areas and the distance from the TV and radio transmitters.
A total of ten sites were chosen to be evaluated. Two types of measurements
were conducted at each site, which are broadband and narrowband
measurements. The narrowband measurements were carried out at the point
where broadband measurement gives the highest reading. Data from a spectrum
analyzer is then analyzed to determine the exposure level. Through
analysis; it was found that the exposure level is well below the safety
guidelines. Therefore, RFR in all ten sites conform to the ICNIRP

repetition code in a high speed vehicular environment for time-sensitive
safety applications. The highly dynamic topology and challenging RF
behavior of vehicular networks necessitate the use of a robust error
control mechanism even with the use of spatial diversity techniques such as
STBC-MIMO scheme. A cross-layer simulator model is used to evaluate the
delay performance of Raptor codes against a low complexity repetition code.
The numerical analysis demonstrates that the end-to-end delay performance
is significantly reduced when Raptor codes are used especially at higher
distances from the source node. This is true in the case of single antenna
as well as multiple antenna schemes."

ABSTRACT="A light yellow amorphous solid (compound A, 760 mg) was isolated from a
silica column chromatography of the crude methanolic leaves extract of
Vitex trifolia. It gave a thin layer chromatographic spot (TLC; Rf = 0.80
in chloroform: methanol = 80:20). Compound A was visible under short UV
light and appeared orange under long UV light. Here, the chemical structure
for A is proposed. In agreement with the preliminary Nuclear Magnetic
Resonance spectrum (1H-NMR, 500 MHz, CDCl3, δH 3 - 12 ppm) and those
reported in the literature, the main skeleton for this constituent might be
a nitrogenous aromatic compound. The signal at δH 3.91 ppm indicates that
A carries a methoxy group. Meanwhile, the signals at δH 5.18 and δH 5.95
ppm shows the possibility of A containing a hydroxyl and a phenolic group.
Another two phenolic protons respectively resonate at δH 7.30 and δH 7.81
ppm. A peak at δH 8.20 ppm would correspond to a proton of a secondary
amine. Next, the peak at δH 11.37 ppm could be assigned either to an
aldehyde group or to a phenolic having the intramolecular hydrogen bonding
with a keto group at its β-position. It is suggested that A could be a
derivative of isoindol-1-one. This finding would enhance the library of
Vitex phytochemicals, in addition to its antioxidative
phenylnaphthalene-type lignan alkaloid and cytotoxic labdane-type
diterpenoids"

ABSTRACT="Voltage instability is the main cause of concern for the large scale
integration of wind power into the power grid. For the induction generator
based wind generation system, the fixed capacitor located at the generator
terminal can not normally cater for the reactive power demand during the
transient disturbances like wind gusts and faults on the system. This paper
presents two schemes for enhancing voltage stability of grid connected wind
generator system. These are, variable susceptance control thru SVC and
reactive power compensation through static compensator system (STATCOM).
Simulation results show that both schemes are well capable of providing
voltage stability and damping transient arising from reasonable level of
disturbances. The STATCOM, however, demonstrates superior performance
because of its fast response capability as well as its ability to provide
compensation independent of system voltage support."

ABSTRACT={This paper proposes a new concept in direct spectrum division transmission.
The transmitter divides the single carrier modulated signal into multiple
{"}sub-spectra{"} in the frequency domain and arranges each sub-spectrum so
as to more fully utilize the unused frequency resources. In the receiver,
the divided sub-spectra are combined in the frequency domain and
demodulated. By editing the divided spectrum in the frequency domain, the
total bandwidth occupied by the multiple {"}sub-spectra{"} is less than
that of the modulated signal. The proposed technique allows the unused
frequency resources scattered across the bands to be better utilized. In
addition, it suppresses the peak to average power ratio (PAPR) compared to
conventional multi-carrier transmission techniques. Simulation results show
that the proposed technique makes the bit error rate degradation negligible
and reduces the PAPR by 1.5dB.}

building routing structures. Their performance however suffers from local
minimums and missing or inaccurate coordinates. Such issues have been
addressed most notably by falling back to face routing or to spanning
routing trees, solutions that require an upfront and global communication
overhead. We propose locally assisting geographic forwarding by resorting
to on-demand route discovery only when and where it becomes necessary. In
simulations we show how this method limits the overhead both spatially and
in quantity, advocating its use to make geographic routing practicable in
large-scale wireless sensor networks."

ABSTRACT="In this paper, the performance limit of lattice sequential decoder for
coded $N\times M$ MIMO channel is analyzed. We determine the rates
achievable by lattice coding and sequential decoding applied to such
channel. The diversity-multiplexing tradeoff (DMT) under lattice sequential
decoding is derived as a function of its parameter---\textit{the bias
term}. Such parameter is critical for controlling the amount of
computations required at the decoding stage. Achieving low decoding
complexity requires increasing the value of the bias term. However, this is
done at the expense of losing the optimal tradeoff of the channel--- hence,
there is a tradeoff. We show how such decoder can bridge the gap between
maximum-likelihood (ML) decoder and low complexity decoders. We argue that,
low complexity decoders such as minimum mean-square error successive
interference cancellation (MMSE-SIC) may achieve close to maximum diversity
gain of the channel $MN$ at very low multiplexing gain."

using an incremental redundancy lattice space-time codes. The optimal
tradeoff has been shown previously to be achieved using a list lattice
decoder for joint detection and decoding. However, such decoder is optimal
only for the high SNR regime and can be prohibitively very complex for
low-to-moderate SNRs. In this paper, we would like to construct a more
efficient decoder that is capable of achieving the optimal tradeoff with
much lower complexity. We show, analytically and via simulation, that using
a modified lattice sequential decoder for joint error detection and
correction in the MIMO ARQ channel, the optimal tradeoff can be achieved
with significant reduction in decoder complexity at a very small

in time-variant flat Rayleigh fading channels. The time-variant fading
channel is modeled by considering the Jakes model and the first order
autoregressive (AR1) model.  Closed-form  expressions of the Cramer-Rao
bound (CRB) for data-aided SNR estimation are derived for fast and slow
fading Rayleigh channels. As a special case, the CRB under uncorrelated
fading Rayleigh channel is derived. A analytical approximate expressions of
the CRB are derived for  low and high SNR that enable the derivation of a
number of properties that describe the bound's dependence on key parameters
such as SNR, channel correlation, sample number. Since the exact maximum
likelihood (ML) estimator is computationally intensive in the case of
fast-fading channel, two approximate solutions are proposed for high and
low SNR cases. Numerical results illustrate the performance of the

ABSTRACT="This paper focuses on the data-aided (DA) direction of arrival (DOA)
estimation of a single narrow-band source in time-varying Rayleigh fading
amplitude. The time-variant fading amplitude is modeled by considering the
Jakes' and the first order autoregressive (AR1) correlation models.
Closed-form expressions of the CRB for DOA alone are derived for fast and
slow Rayleigh fading amplitude. As a special case, the CRB under
uncorrelated fading Rayleigh channel is derived. A analytical approximate
expressions of the CRB are derived for low and high SNR. A high
signal-to-noise-ratio maximum likelihood (ML) estimator based on the AR1
correlation model is derived. The main objective is to reduce algorithm
complexity to a single-dimensional search on the DOA parameter alone as in
the static-channel DOA estimator. Finally, simulation results illustrate
the performance of the estimator and confirm the validity of the
theoretical analysis."

ABSTRACT="P2P TV and video streaming are among the most bandwidth-hungry applications
running over the Internet. Indeed, the impact of P2P TV over networks is
enormous and can jeopardize the entire system. One of the main reasons is
that the scheduling of information transfer between peers is  extremely
aggressive and does not take network characteristics into account.
Moreover, schedulers are not designed to be robust and configurable, so
that their performance is greatly affected by networking conditions. This
work first analyzes how the network heterogeneity impacts the performance
of different schedulers (chunk and peer selection strategies) and then
propose a novel, robust, configurable, network-aware scheduler that
outperforms the other schedulers in all networking scenarios with respect
to all the performance metrics (chunk loss, maximum delay, average delay,
... )."

clients, all based on our modular software libraries called GRAPES (Generic
Resource-Aware P2P Environment for Streaming), and we show how different
design and architectural choices affect both the received video quality and
the network usage. In particular, the use of network-level measures to
optimize both the overlay topology and the chunk scheduling enables the
applications to achieve optimal video quality (smooth streaming with low
delays) without increasing network usage. Moreover, the interaction with an
ALTO prototype Server (see RFC 5693), in order to obtain information form
network providers further improves performances. During the demo we change
different parameters of the P2P client, like chunkization strategies,
scheduling policies, etc. as well as characteristics of the distribution
system itself such as churn intensity and distribution, the
presence/absence of an ALTO server (and the information it provides), and
show how a correct design and parametrization can make P2P-TV viable

ABSTRACT="The traditional technique for conceptualising spillovers has being in terms
of productivity gains. However, there is now a growing literature that
focuses on the process through which firms in developing countries acquire
technological capabilities. Following on this re-conceptualisation, the
effect of spillover mechanisms from the foreign firms on the technological
capability, specifically production capabilities, of the domestic small and
medium companies in food companies (SMFCs) in Nigeria was studied.

Data were collected from the SMFCs using multi-stage sampling technique,
firstly by purposively chosen three States in Southwestern Nigeria where
the activities of multinational companies are prominent. Secondly, the
population frame was classified into five sub-sectors, which include Fruit
juices and Drinks; Bakery products; Beverage; Wines and Spirit; and Dairy
products. Lastly, a population sample of 200 food companies was selected
through a stratified random sampling technique. The research tool employed
was questionnaire technique, which elicited information on the impact of
spillovers from MNCs on the production capability of these food companies.
The percentage distribution of the increases in sales, profit, and market
share of each company as a result of spillover was also computed.

The result of the composite spillover index shows that majority (61.5\%) of
the domestic food companies had index of 4, with only 4.5\% having index of
5. None of the companies had index of 6 or 7. This shows evidences of
technological spillovers in the production capability of these companies.
However, the extent of these changes was moderate. The impacts of the
spillovers on sales, profit, and market shares of the food companies were
also minimal. This is because most of them indicated percentage increase in
sales, profit, and market shares of between 1\% and 5\%. This implies that
foreign direct investment (FDI) has only promoted a minimal innovation in
the domestic food companies. While FDI is providing an important source of
capital in the country, the impact on future opportunities for catching up
technologically is minimal. Therefore, FDI promotion should be situated in
a long-term development process whose goal should be to strengthening
innovation capabilities of the local companies."

ABSTRACT="This paper considers performance anomaly in multi-rate IEEE 802.11 wireless
LANs, where stations (STAs) with the lowest data transmission rate regulate
the throughput of all other STAs and the total system throughput degrades
badly. Previous work suggests that achieving air-time fairness is a
reasonable way to solve the performance anomaly and most of related works
aim at air-time fairness in STA-level. Since the AP handles multiple
downlink flows, however, air-time fairness in STA-level leads to serious
performance degradation of downlink flows. Aiming at air-time fairness in
flow-level, this paper proposes a dynamic window control of uplink and
downlink flows. In the proposed system, flows are classified into several
classes according to their data transmission rates, and at APs, downlink
flows in respective classes are stored in separate buffers. Further the
proposed system assigns different CWmin's to those classes according to
their data transmission rates and the target packet rates. Through
simulation experiments with UDP and TCP, we show the excellent performance
of the proposed system."

This behavior is explained considering the dynamics of the vehicle and the

ABSTRACT={The emergence of powerful numeric and symbolic scientific software
applications, including Matlab, Maple, and Mathematica, has revolutionized
engineering design. They have allowed users to perform computations and
calculations with a level of sophistication and depth that was not
available to practitioners even one generation ago. They have also given
educators the ability to convey advanced mathematical and engineering
concepts in new ways. This new capability, which has become a fundamental
tool for sophisticated designers in industry, is still making only
preliminary and halting steps in the standard engineering curriculum.
Rather than being at the core of this curriculum, scientific computation is
often considered an addition or an external assistance tool. The reality is
that traditional ‘by hand’ techniques are being made obsolete by the
new tools, and they often survive nowhere in the engineering enterprise
except the antiquated engineering classroom... The reality is that students
who would lack scientific software skills in 2015 will not be ready to
practice engineering in 2015, as manifested by the already-prevalent use
sophisticated software tools, especially tools for symbolic computation, in
industry. These tools should be presented {"}right at the beginning,{"}
when basic mathematical concepts and techniques are presented to first and
second year engineering students, and should be a permanent companion of
the engineering student and the engineer. This is not to say that no
experience should be provided with classical analytical techniques. However
the major focus should be on explaining to our students how to harness the
available advanced tools to address nontrivial problems and not on drilling
trivial examples by hand. The analogy to what many of our programs do is to
teach intelligent shortcuts and smart techniques for multi-digit number
multiplication; such techniques exist, they are aesthetically pleasing and
quite sophisticated, yet we do not do teach them anymore because our
students (and us) use electronic calculators. 

While engineering students should still be introduced to the core concepts
of probability, calculus, and linear algebra, the use of scientific
software would allow even first and second year students to investigate
with relative ease concepts and problems that were once reserved only for
advanced researchers. To demonstrate how this can be done, we updated the
first and second year engineering curriculum at Drexel University to place
scientific software as a core learning tool. These scientific software
tools widened the scope of the challenges presented to our students well
beyond traditional ‘solve by hand’ textbook problems. In addition,
students taking these courses developed a working knowledge of modern
scientific software packages that provided them with valuable skill sets
for careers in the industry. 

An example of the challenges we presented to our students was to model a
geosynchronous satellite orbit insertion problem as a system of coupled
second order nonlinear differential equations and simulate the system using
MATLAB. In this paper we use this example to illustrate our past and
current efforts to develop courses with scientific software as the core
learning tool, and the outcomes in terms of the students’ exposure to
advanced technical concepts, skill set development, and overall learning
experience.}

ABSTRACT="In this paper a new technique called The HandOver Decision STAbility
Technique (HODSTAT) is proposed for horizontal handover in Wireless Local
Area Networks based on IEEE 802.11 standard. HODSTAT addresses the decision
instability which impacts negatively on both user perception and network
performances. HODSTAT is based on a hysteresis margin analysis that,
combined with a utility-based function, evaluates the need for the handover
and determines if the handover is needed or can be avoided. Indeed, if a
Mobile Terminal (MT) only transiently hands over to a better network, the
gain from using this new network may be diminished by the handover overhead
and short usage duration. The approach that we adopt throughout this
article aims at reducing with the minimum handover occurrence that leads to
 network connectivity cut  which causes additional delay and packet loss.
To this end, MT rather performs a handover only if the connectivity of the
current network is threatened or if the performance of a neighboring
network is really better comparing to the current one with a hysteresis
margin. This hysteresis should make a tradeoff between handover occurrence
and the necessity to change the current network of attachment. Through our
extensive simulation results, we show that our proposed algorithm
outperforms other decision stability approaches for handover decision
algorithm."

fairness. Our simulation results show that when there is a single provider,

ABSTRACT="Photoplethysmography (PPG) is a Photoelectric technique that asses the
peripheral circulatory changes. It is widely employed as a useful
analytical method in physiological and cardiovascular diagnosis.The PPG
signal quality is important to ensure accurate measurements. This paper
explores a signal processing module to improve its quality, particularly
for the cases of the low signal amplitude and relatively poor
signal-to-noise ratio (SNR). The proposed module consists of two stages,
differential amplifier that retains high common-mode rejection ratio (CMRR)
and a programmable gain amplifier. The main features of the PPG pulse
waveform are the values and the locations of its peaks and valleys that are
considered as the cornerstone of any computerized pulse diagnosis. A robust
peak and valley detection algorithm was developed in LabVIEW. It is based
on deducing the dominant signal frequency, a low pass filter and
peaks/valleys detection VI. Results showed that the proposed algorithm is
highly effective in extracting the desired peaks and valleys. SNR was taken
as an indicator that is commonly used to evaluate the PPG signal quality.
By applying the developed signal processing module, the extracted PPG
signals exhibit a relatively good quality. Where, the SNR value of signals
is better than 40 dB."

ABSTRACT="Advances in DNA microarray technology has motivated the research community
to introduce sophisticated techniques for analyzing the resulted
large-scale datasets. Biclustering techniques have been widely adapted for
analyzing microarray gene expression data due to its ability to extract
local patterns with a subset of genes that are similarly expressed over a
subset of samples. Mostly, biclustering methods are based on greedy
heuristics which often result in suboptimal solutions. To this end, this
paper presents a clonal selection algorithm for biclustering (Bic-CSA) that
incorporates these greedy searching procedures as local search heuristics
in an immune-inspired algorithm. The quality of biclusters has been
demonstrated by experimentation on a well known benchmark dataset.
Moreover, the performance of Bic-CSA is compared with other related local
search-based methods and immune inspired algorithms. It is shown from
results and comparative study that the proposed algorithm outperforms other
algorithms in terms of bicluster size and mean-squared residue."

synthesized by free radical polymerization of acrylamide monomer. The
synthesized gel exhibited an abnormal rheological behavior. The grafting
technique enhanced the zero-shear viscosities of CO PAM-AA solutions.
Dynamic rheological measurements suggest that the higher viscosities of CO
PAM-AA are due to the increase in the stability of hydrophobic junctions in
the polymer-surfactant network. The relationship between the viscosity and

with smaller coherence is desired. In this paper a gradient descent method
is proposed to optimize the measurement matrix. The proposed algorithm is
designed to minimize the mutual coherence which is described as absolute
off-diagonal elements of the corresponding Gram matrix. The optimization is
mainly applied on random Gaussian matrices which is common in CS. An
extended approach is also presented for sparse signals with respect to
redundant dictionaries. Our extensive experiments yield promising results
and show higher reconstruction quality compared to those of both

the mutual coherence. Defining a new cost function, we suggest to use a
steepest descent algorithm for this optimization problem. The advantages
are less computational complexity, which makes the method suitable for
large-scale problems, more robustness, and higher incoherence between the

ABSTRACT={Today in developing countries there seems to be an overwhelming surge of
tendency toward providing the state of art technologies for both public and
private organizations. Nevertheless, normally the costs of these projects
are not covered by their productive and strategic deployment and
implementation. Generally, there is a ritualistic approach among decision
makers and managers in developing countries regarding the information
technology. This approach can lead to the change of conceptions, which
means technology instead of being a facilitator alters to an obstacle in
the path of success and improvement. Development of a nation is largely
dependent on the success and competitiveness of its companies. One of the
contributing factors to the successful deployment of a technology in
organizations is considered to be alignment between Technology strategies
and organizational objectives. For companies to succeed in the increasingly
competitive, information-intensive and dynamic environment the alignment of
business strategy and technology strategy is a necessity. The strategic
alignment model, the framework for this study, is based on the theoretical
construct developed by Henderson and Venkatraman (1990). This model
explores the interrelationship between business and IT. It is based on two
distinct linkages: strategic fit and functional integration. Despite the
enormous academic and practical adoption of this framework it seems to have
deficiencies in proposing the required implementation guidelines which has
formed a gap in its application. Therefore, this paper has proposed a
modified version of HOQ (House of Quality) and it has been called
{"}IT-alignment House of Quality{"}. It is based on the fundamental
concepts and procedures of a traditional QFD, although the input of the
tool is coming from our research’s context Venkatraman’s IT-alignment
Framework, where our ultimate purpose lies. Financial sector is one of the
most critical pillars in the construct of economic development specifically
in the third world countries. Since banks are considered to be one of the
major entities of financial sector, the role ICT plays has inevitable
effects on efficiency and productivity of the country, in order to increase
the reliability of the mentioned model , it has been piloted in Mellat Bank

alpha |X|^n iii) f(X) = alpha |X|^1/q iv) f(X) = alpha sgn(X) |X|^1/q,
for all  alpha in R^*, n in N^* and q in N^* - {1}.

Subject to an average power constraint, we study the capacity-achieving
input distributions of these classes of channels and prove them to be
discrete except for the linear case f(X) = alpha X, where the optimal input
is Gaussian distributed. Furthermore, we prove that these optimal input
distributions have a finite number of mass points for classes iii) and
iv).

The results are reached through the development of a methodology and tools
that are based on standard decompositions in a Hilbert space with the
Hermite Polynomials as a basis, and we conjecture that these bases are
natural candidates for general information-theoretic studies of the
capacity of channels affected by additive white Gaussian noise."

are proposed. In the iterative ZF-based scheme, all interference
is canceled by using the transmit-receive weights. To reduce the
complexity of iterative ZF scheme, in the iterative THP-based
scheme, the interference is canceled by using transmit-receive
weights and the THP. To achieve symbol error rate (SER) fairness
among different users and further improve the performance of
multi-user MIMO relay systems, we develop optimal and suboptimal
power allocation (PA) methods that ensure signal-to-interference-

under the power constraints at both BSs and relay station (RS).
In the optimal PA scheme, the PA is done at both BSs and RS. In
the sub-optimal scheme, to reduce the computational complexity
of optimal PA significantly, the PA is done only at BSs, and
at the RS a power scaling is performed to satisfy the RS power

sources communicate to an access point (AP) in the presence of block-faded

sensor networks, where information may be exchanged between a multitude of
nodes. Our goal is to explore the potential benefits which can be obtained
when source correlation is exploited at the AP, comparing the performance
with that obtained by using distributed source coding (DSC) at the nodes.
We consider both the average bit error probability and the outage
probability as performance indicators, and we derive a theoretical approach
to evaluate their limits. Our results show that the improvement brought by
the exploitation of the correlation at the AP is more evident when the
correlation becomes sufficiently high. Moreover, some simulation results
are presented for two classes of channels codes: serially concatenated
convolutional codes (SCCCs) and low-density parity-check (LDPC) codes. Our
results show that SCCCs can exploit better the correlation in scenarios

ABSTRACT="In the recent years mobile robotic applications have increasingly benefited
from the possibility of building maps of unknown environments and of
localizing therein. Localization and map building are closely related
problems, and are often referred as simultaneous localization and mapping
(SLAM).A possible solution to the SLAM problem uses feature-based models of
the environment and the Extended Kalman Filter (EKF) to manage the
associated uncertainty. This approach is extremely compact, but the
technique may fail in handling unstructured environments, due to the
limited set of feature models used. Another solution employs particle
filters. This approach has the advantage that manages the uncertainties
present in the problem, but it suffers from a high computational cost due
to the number of particles required. Some attempts have been made to solve
this problem Many real robotic applications, however, require updated maps
of the environment that vary over time, starting from an initial known
condition. In this context classical SLAM approaches are generally not
directly applicable: such approaches only apply in static environments or
in dynamic environments where it is possible to model the environment
dynamics. The problem faced here is instead related to long-term mapping
operativity in presence of variations in the map. This is for instance the
case of robotic applications in logistic spaces, where rovers have to track
the presence of goods in given areas. The goods are stored in appropriate
places, but during the day they can be removed and inserted again many
times. The proposed solution maintains an updated grid map of a dynamically
changing environment and is divided in functional blocks. The solution must
have long-term operativity and the algorithm performing the map update has
to be computationally light and use limited memory. Simulation results
validate the proposed approach."

ABSTRACT="Use of multiple transmit waveforms to enable MIMO radar operation is a
technology with strong application to HF over-the-horizon (OTH) radar. We
consider the problem of target detection when the OTH radar is operating in
an environment with a stable ionospheric propagation path supporting high
quality Doppler spectra from backscattered signals and clutter, and a
perturbed ionospheric propagation path which contaminates the signal with
spread-Doppler clutter. In this case, efficient spread-clutter mitigation
requires elevation and azimuth beampattern control via 2-D arrays. In
addition, due to the propagation geometry, the beampattern control needs to
range-dependent for both transmit and receive antenna arrays, mandating the
use of the MIMO radar architecture. We examine the impact of antenna
geometries on clutter mitigation performance. We also provide performance
analysis for a specific configuration employing 1-D transmit and receive
antennas which enables field experiments that validate MIMO OTH radar
operations."

ABSTRACT="A mix is a communication proxy that hides the relationship between incoming
and outgoing messages. Routing traffic through a path of mixes is a
powerful tool for providing privacy. When mixes are used for interactive
communication, such as VoIP and web browsing, attackers can undermine user
privacy by observing timing information along the path. Mixes can prevent
these attacks by inserting dummy packets (cover traffic) to obfuscate
timing information in each stream. A recently proposed defense called
adaptive padding makes cover traffic more effective by ensuring that
statistically unusual gaps between packets are partially filled in with
dummy packets. In this work, we propose Selective Cross Correlation (SCC),
an attack that an eavesdropper could employ to de-anonymize users despite
the use of adaptive padding. The main insight of our approach is that, with
the defense, the timings at one end of the stream are effectively a subset
of the timings at the other end of the stream. By considering the network
conditions, an appropriate correlation window can be found and used to
effectively remove the cover traffic, thereby enabling us to correlate both
ends of the stream. We have conducted real network experiments and have
found that SCC greatly improves attacker effectiveness over prior
techniques against the defense. With SCC, the attacker is nearly as
successful as when no defense is applied. This attack demonstrates the need
for more robust defenses against statistical timing attacks."

ABSTRACT="Recently, multi-touch tabletop displays provided the Natural User Interface
(NUI). Humans use the bare finger as a pointing device to manipulate
interactive elements on multi-touch surface. However, fingertip size
occupies the large space instead of appropriate target point and creates
ambiguity in touch detection. However, to overcome this issue possibly, we
developed an optical multi-touch screen using a Frustrated Total Internal
Reflection (FTIR) sensing technique to investigate the fingertip blobs. We
specified interaction mechanism of finger touch which brings the stability
in touch detection. When users touched the surface using the finger, we
obtained the number of fingertip blobs and kept as record for
investigation. We took each fingertip blob as an image and processed in an
image processing tool to compute the relative threshold value. It is
observed that, each fingertip image has a unit variance in threshold value
due significant variation of fingertip size of every subject. It may create
the ambiguity in finger touch detection. The other factors which may cause
of ambiguity such as dispersed pulp of fingertip, and low brightness of
fingertip blobs. This study augments to understand the factors which affect
on accuracy of finger touch detection and give guidelines to achieve the
accuracy."

ABSTRACT="Recent advances in Intelligent Transportation Systems (ITS) and the growing
number of applications in Vehicular Networks (VN) have attracted many
researchers. Applications in Vehicular Networks comprise but are not
limited to safety applications and convenience applications. Deploying
Vehicular Networks widely cannot be accomplished without overcoming the
existing research challenges in such networks. Service discovery is one of
the main challenges in Vehicular Networks which are characterized by their
large scale and high mobility. Existing service discovery techniques for ad
hoc networks cannot be applied directly to Vehicular Networks scenarios due
to their poor performance and decreased efficiency in Vehicular Networks.
In this paper, we present our location-based service discovery protocol for
Vehicular Networks (LocVSDP). Our protocol permits the discovery of
location-aware and time-sensitive services in Vehicular Networks. Moreover,
our LocVSDP protocol improves service discovery efficiency by integrating
service information into the network layer and using diverse channels. In
our protocol, we present our efficient mechanism that permits to service
requesters to find service providers and their routing information
simultaneously, which results in overall bandwidth savings. We make use of
diverse channels for the exchange of discovery and routing packets, which
decreases the congestion on single channels and improves the delay of
service discovery. Then, we present our efficient location-based request
propagation and an efficient computation of the service reply, based on the
specified location of the requested service in the driver's request. We
discuss the implementation of our protocol and present its proof of
correctness."

ABSTRACT="Recent studies on service discovery protocols in vehicular networks have
shown promising results. However, very little work has been reported on how
to integrate the fault tolerance feature into these mechanisms. This
feature is vital for the success of the deployment of service discovery
protocols in vehicular networks. Drivers on their cars should not have
their requests dissatisfied or their connections dropped because a service
provider or some components between the service provider and the service
requester have failed. In this paper, we present a fault tolerant location
based service discovery protocol for Vehicular Networks. The main
advantages of our protocol is its ability to tolerate service providers
failure, communication links failure and roadside routers failure. We
present our fault tolerant protocol, and report on its performance
evaluation. Our simulation experiments show that our proposed fault
tolerant LocVSDP algorithm improves the success rate significantly over the
basic LocVSDP. In fact, the success rate is improved in the roadside
routers failures scenario and in the links failures scenarios by 50 percent
and 30 percent respectively."

ABSTRACT="A {\em power assignment} is an assignment of transmission power to each of
the nodes of a wireless network, so that the induced communication graph
has some desired properties. The {\em cost} of a power assignment is the
sum of the powers. The {\em energy} of a transmission path from node $u$ to
node $v$ is the sum of the squares of the distances between adjacent nodes
along the path.
For a constant $t > 1$, an {\em energy $t$-spanner} is a graph $G'$, such
that for any two nodes $u$ and $v$, there exists a path from $u$ to $v$ in
$G'$, whose energy is at most $t$ times the energy of a minimum-energy path
from $u$ to $v$ in the complete Euclidean graph.

In this paper, we study the problem of finding a power assignment, such
that (i) its induced communication graph is a `good' energy spanner, and
(ii) its cost is `low'. We show that for any constant $t > 1$, one can find
a power assignment, such that its induced communication graph is an energy
$t$-spanner, and its cost is bounded by some constant times the cost of an
optimal power
assignment (where the sole requirement is strong connectivity of the
induced communication graph). This is a very significant improvement over
the best current result due to Shpungin and Segal~\cite{Shpungin},
presented in last year's conference."

ABSTRACT="Gradually, Voice over Internet Protocol (VoIP) has been dominating the
telecommunications world. Unfortunately, its applications are injecting a
huge number of small packets in the network, which produces high overhead

novel multiplexing technique, Delta-Multiplexing, to save the wasted
bandwidth. In the Delta-Multiplexing technique, the VoIP packets destined
to the same destination gateway are aggregated in a single UDP/IP header,
therefore reducing the header overhead and saving network bandwidth.
Moreover, the Delta-Multiplexing technique reduces the size of the packets
payload by transmitting the difference between the consecutive packets
payloads. Accordingly, the Delta-Multiplexing technique greatly saves
bandwidth. We have simulated the Delta-Multiplexing technique using a
14-byte LPC codec. The result showed that Delta-Multiplexing is capable of
saving between 68\% and 72\% as compared to conventional techniques
(without multiplexing). Moreover, the Delta-Multiplexing technique reduces
the number of VoIP packets running over the network, therefore reducing
network traffic, overload, and congestion, thus improving the overall

random distribution where the thresholds of the uniform random variable are
associated with the contribution factors. This approach guarantees fairness
in allocating the resources in each relay. The approach is compared with
static allocation of the OFDM sub-channels. The MARS strategy is tested in
a multi relay system over flat and selective Rayleigh fading channels.
Simulation results show the superiority of the proposed scheme in improving

creating a virtual diversity by randomizing the allocation where no channel

ABSTRACT="The capable of structures to absorb large amount energy are great interest,
particularly in vehicle and transportation in an effort to reduce the
impact for the case of collision. During the actual collision, the crash
box not only experienced axially but in both axial and oblique crash. In
this research, an experimental investigation was carried out to study the
crashworhiness parameter and behavior of pultruded fiber E-glass/polyester
composite tubes. Quasi-static loadings were applied axially and oblique on
pultruded composite to investigate the response of force-displacement
during progressive collapses. The pultruded wall thickness of 6 mm tubes
were used and four angle 0˚, 5˚, 10˚ and 15˚ were selected to study
their effect on crushing behaviors and collapse modes. Load-displacement
curves and collapse mode of each sample were discussed. All specimens were
chamfer 45˚ on top end as purpose to work as a collapse trigger mechanism.
The result showed that increasing the angle will decrease the energy
absorption of the structures."

ABSTRACT="Self compacting concrete (SCC) was developed in late 1980s in order to
improve the performance of concrete in its fresh state particularly when
used in narrow formwork with congested steel reinforcement. The fundamental
aims of the development were to enhance the flowability, self-compacting
ability and segregation resistance using superplasticisers. This paper
presents the results of the compressive and flexural behaviour of SCC beams
tested under different loading rates. Cubes of SCC and normally compacted
concrete (NC) were casted to test for compressive strength. A four-point
static beam-load test was performed on SCC and NC beams subjected to the
loading rates of 0.01 kN/s, 0.2 kN/s and 15 kN/s. Cube compressive
strength, beam failure load, flexural modulus and the cracking pattern of
SCC were obtained and compared with the normally compacted concrete. This
study revealed that the hardened behavior of SCC is very similar to NC. In
general, SCC developed higher early strength (compressive) as compared to
NC of the same strength category. The maximum failure load of the SCC beam
was also 6 to 9\% higher than that of the NC beam for all loading rates.
SCC exhibits longer non-linear behavior, which shows that it is very
ductile compared to NC. SCC also developed less number of shear crack than
NC, and the beams failed in flexure especially at high loading rate due to
confinement effect."

ABSTRACT="With the introduction of the World Wide Web and graphical browsers in the
1990s the Internet has become widely accessible and many people have
grabbed the idea of using it for their multifarious purposes and agenda.
They have established all types of websites to foster their mission and
visions. They recognize that Internet can enhance their scale of
communication through the websites as the Internet is capable of delivering
large quantities of information in a speedy manner to the public. It is not
surprising therefore that Muslims believe that the websites are the most
useful platform to disseminate Islamic knowledge and information. The most
important website that Muslims interact with is the Holy Quran website.
Higher quality websites tend to attract more links and rendered those
websites as highly visible. Using a software, Alexa, it is possible to
gauge the volume of web traffic in order to determine the visibility of the
website. In this paper Alexa is applied to study the visibility of Quranic
websites. Nine quranic websites were investigated. It was found that the
website, almushaf.com is the most visible website. It is futile to have a
website that is difficult to access by users owing to non compliance with
the accessibility guidelines. To check whether a particular Al-Quran
website conforms or not to the accessible guidelines a software, A-Prompt
could be used. The A-Prompt is able to examine the Al-Quran websites for
barriers to accessibility, and at the same time is able to perform
automatic repairs of the respective websites. Applying A-Prompt it was
found that the most inaccessible website is the qurancomplex.org."

ABSTRACT="The advances of information and communication technology (ICT) have
tremendously affecting the way teaching and learning is delivered in both
formal and informal education. For formal education, Malaysia is reaping
the benefits of ICT in formal education through Smart School project under
MSC Malaysia initiatives. For informal education, an initial observation
suggests that museums, a critical institution which protects and preserves
the national heritage as well as delivers the knowledge to the general
public, employ less ICT in their exhibition halls. As there is lack of
empirical evidence to prove the above, this study aims to determine the
level of ICT use by museums in Malaysia and attempts to understand issues
that have profound influenced on ICT implementation in their institutions
and hence in their exhibition halls. An exploratory survey was conducted
with 22 governing institutions for museums throughout Malaysia. The
findings suggest that museums have complete ICT infrastructure, services,
and applications to run day-by-day administration and operations. However,
there are rooms for improvement when it comes to museum exhibition halls.
This study further reveals several issues that restricted these museums
from using ICT as one of the means for historical, cultural, and heritage
knowledge to be delivered to the general public."

ABSTRACT="The nodes in a wireless sensor networks often collect correlated
measurements. Not taking into account this information redundancy is
detrimental to the network lifetime, since communication is often the most
energy consuming task for a sensor node. This paper tackles this issue by
proposing an approach based on Distributed Source Coding (DSC), in which
the rate assignments are adapted over time. The distinctive feature of the
DSC technique is to make the compression independent of the routing. We
rely on this feature to design two algorithms applicable to multi-hop
routing trees, where the routing and the coding are jointly optimized. The
first algorithm is the Updated CMAX (UCMAX), which improves the centralized
CMAX routing algorithm, by considering the energy loss due to packet
forwarding in multi-hop networks. The second algorithm is called Adaptive
Compression Rate (ACR), and aims at maximizing the network lifetime by
better balancing the energy losses in the network. Experimental results
show that the proposed approach is easy to tune, and may significantly
extend the network lifetime, particularly for dense, multi-hop networks."
