This work proposes a pattern recognition model for static gestures in Malaysian Sign Language
(MSL) based on Machine Learning (ML) techniques. The proposed model is divided into two
phases, namely, data acquisition and data processing. The first phase involves capturing the
required sign data, such as the shape and orientation of the hand, to construct a sensor-based SL
dataset. The dataset is collected using a DataGlove device. This device is used to measure the
motions of the fingers and wrists. Sixty-four features represent each sign in the dataset. The
collected sensory dataset is cleaned in the second phase by removing redundant data. Then, the
features are scaled and normalized to exhibit symmetrical behavior and eliminate outliers. Then,
ten different ML techniques are utilized based on real-time data for SL gesture recognition.
Experimental results confirmed the efficacy of the proposed pattern recognition model compared
with previous work.

Wireless Sensor Networks (WSNs) are event-driven network systems consist of many sensors node which are
densely deployed and wirelessly interconnected that allow retrieving of monitoring data. In Wireless sensor network,
whenever an event is detected, the data related to the event need to be sent to the sink node (data collection node). Sink node
is the bottleneck of network there may be chance for congestion due to heavy data traffic. Due to congestion, it leads to data
loss; it may be important data also. To achieve this objective, soft computing based on Neural Networks (NNs) Congestion
Controller approach is proposed. The NN is activated using wavelet activation function that is used to control the traffic of
the WSN. The proposed approach which is called as Modified Neural Network Wavelet Congestion Control (MNNWCC), has
three main activities: the first one is detecting the congestion as congestion level indications; the second one is estimated the
traffic rate that the upstream traffic rate is adjusted to avoid congestion in next time, the last activates of the proposed
approach is improved the Quality of Services (QoS), by enhancement the Packet Loss Ratio (PLR), Throughput (TP), Buffer
Utilization (BU) and Network Energy (NE) . The simulation results show that the proposed approach can avoid the network
congestion and improve the QoS of network.

The importance of image encryption has considerably increased especially after the dramatic evolution of the internet of things (IOT) and due to the simplicity of capturing and transferring digital images. Although there are several encryption approaches, chaos-based image encryption is considered the most appropriate approach for image applications because of its sensitivity to initial conditions and control parameters. This research aims at generating an encrypted image free of statistical information to make cryptanalysis infeasible. Therefore, a new method was introduced in this paper called Multi-layer Chaotic Maps (MLCM) based on confusion and diffusion. Basically, the confusion method uses the Sensitive Logistic Map (SLM), Hénon Map, and the additive white Gaussian noise to generate random numbers to be used in the pixel permutation method. However, the diffusion method uses Extended Bernoulli Map (EBM), Tinkerbell, Burgers, and Ricker maps to generate the random matrix. The correlation between adjacent pixels was minimized to have a very small value $(x 10-3)$. Besides, the keyspace was extended to be very large $left(2^{450} ight)$ considering the key sensitivity to hinder brute force attack. Finally, a histogram was idealized to be perfectly equal in all occurrences and the resulted information entropy was equal to the ideal value(8), which means that the resulted encrypted image is free of statistical properties in terms of histogram and information entropy. Based on the findings, the high randomness of the generated random sequences of the proposed confusion and diffusion methods is capable of producing a robust image encryption framework against all types of cryptanalysis attacks.

Abstract. The aim of this paper is to determine the performance enhancement of the network
for eliminating congestion through the use of the benefits of algorithms. These algorithms can
be used in hindering the congestion which may occur within the network that relies on a
Transmission Control Protocol (TCP) protocol. This paper specifically focuses on
demonstrating the function of TCP, and most especially the four (slow start, congestion
avoidance, fast retransmit and fast recovery algorithms) that are applied in the control of
congestion. In the study, the varying effects of connection link from PPP DS1 to PPP DS3 on
the network’s performance are investigated.

Abstract— A wireless sensor network (WSN) has
significant applications such as monitoring the far
environmental and target tracking. This has been enabled
by the sensors that are smaller, cheaper, and intelligent.
These sensors are equipped with wireless interfaces that can
communicated with each other to form a network. The
design of a WSN depends significantly on the application,
and it must consider factors such as the environment, the
application’s design objectives, costs, hardware, and
system constraints. However, the nodes closer to the sink
in the network are overburdened with huge traffic loading
known as hot spot problem as the data from the total region
are forwarded through them to reach the sink node. As a
result, their energy gets consumed quickly and the network
is subdivided in to multiple region. This paper aims to study
the grid based random clustering and grid based static
clustering techniques in WSN and to evaluate the
performance and compare between them by via simulation.
The results show that grid based static clustering
outperforms random clustering in term of throughput by
22%, reduces energy consumption by 30%, and increase
residual energy by 20%. Thus, the network lifetime of the
WSN will be prolonged.

Online Examination is an essential ingredient in electronic and interactive learning, however, in educational environment most of examinations are done in the classical paper-based way due to the lack of resumption capability when power/network/physical computer’s component failures. For this reason, adopting and developing an online examination system acts as an active research area in recent years. This paper reviews the state-of-the-art and the-art-of-the-practice for nine general-purpose online examination systems found in the literature, as well as, some dedicated industrial systems based on seven elected intertwined features; namely: secure login, resumption capability, multi-instructor, random question selection, random questions distribution, random choice distribution, and portability implementation method. Even though, the implementation of these systems is promising, however, these systems have some bleeding points. For instance, by practicing the existing examinations system, some challenging features are found and others are missing. Among these features; namely: the resumption capability and the combination of randomization features are missing in the reviewed systems. Fix and build from earlier works, this paper proposes an Online Examination System (OLES) that addresses all the elected features to facilitate adopting online examination. OLES is based on spiral model and TCP-IP client/server networking and implemented using Java programming language and Derby database. Finally, a comparison of the proposed OLES versus other related works to distinguish its unique features, and some recommendations for future work are provided.

The impact of utilizing Nanofluids with different metal oxide nanoparticles on heat transfer enhancement and fluid flow for concentration photovoltaic thermal the CPVT collector with Fresnel lens is demonstrated using CFD simulation. With the rising temperature, the electrical efficiency and output power of Multi-Junction Solar Cells drop. Four different types of nanofluids and water are utilized as cooling fluids to disperse heat from Multi-Junction Solar Cells by moving the fluid within the mini-channel beneath the PV Solar Cells. In the current analysis, the Reynolds numbers range from 2000 to 18000. For all forms of cooling fluids, the average Nusselt numbers are augmented by rising Reynolds numbers. The CFD results demonstrated that the Nusselt number of all nanofluid cooling fluids is greater than that of water. When compared to water in a CPVT collector, water-SiO2 nanofluid provides the maximum heat transfer improvement of 12.5%. The silicon dioxide nanoparticles have high thermal conductivity, with the water-SiO2 nanofluid exhibiting the greatest heat transfer increase, followed by water-Al2O3, water-ZnO, water-CuO, and water. The average top surface temperature of the mini-channel for the CPVT collector is reduced by 7% when water-SiO2 nanofluid is used as a cooling fluid and by 3.4% when water is used. The usage of water-SiO2 nanofluid has a significant impact on the heat dissipation with high heat transfer enhancement from Multi-Junction Solar Cells in CPVT collector, leading to an increase in electrical efficiency.
