YHA Rahim
The presentation considers the modelling of multi-machine power networks for the purpose of analysis of transient and steady state stability. The present complexity and ever-increasing size of interconnected power systems have generally led to operating conditions where there are large load angles between generators at remote ends. This reduces limits of synchronous power flow and produces low frequency oscillations [2), and hence leads to a decrease in the over all stability of the system. Because of the continuous increase in demand of electrical power, generators of increased size are continually added to the systems,and units of ratings greater than 1000 MVA are now in service. Generator units of 2000 MVA output are considered as of economical size by 1990s. However, the trend in the parameters of such large conventional machines,also reduces stability.
YHA Rahim receieved his B.Sc., Second Class Honors, University of Khartoum, Department of Electrical Engineering and Electronics, September 1971. Receieved his Ph.D., University of Liverpool, Department of Electrical Engineering and Electronics, UK., Dec. 1975. YHA Rahim was the vice chancellor, Karary University, Sudan since 2002, Dean College of Engineering, Karary University, 1995, and Dean College of Engineering, Sudan University of Science 1994.
With the fast development of smart integrate circuit (IC) technology, electrical devices, especially power metal oxide semiconductor (Silicon) filed effect transistors (MOSFET), play more and more important roles in several products and applications, especially in personal computer and cell phone technologies. Thus, new generation smart IC technology needs to provide higher performance product with lower cost. This is not an easy goal to achieve because there are still several problems faced by the device engineers. Two of the most important problems are temperature and electrical stresses encountered by these devices. This talk focuses on power MOSFETs performance and thermal stability, and discusses their long-term reliability in terms of devices degradation before and after the application of accelerated thermal and electrical stresses. There stresses are meant to mimic the accumulated stresses developed on the device as a result of operating the device for a long time under its typical operating conditions. The characterization techniques employed include: SEM, current-voltage temperature and capacitance voltage temperature measurements, charge pumping, and deep level transient spectroscopy.

Professor Lenan WU
Radio spectra in space are close-packed more and more, so its impact of frequency as a valuable resource is increasingly prominent. But whether we can make the transmission bandwidth “ultra narrow” and the data rate even higher, and keep the power transmitted in an acceptable level, what needs surveying is the theory of digital communication and the technology of modulation/demodulation. The Ultra Narrow Band (UNB) modulation is just a sort of transmission technique with efficient-bandwidth and high data rate reported, but its principle and methodology still needs clarifying. So this paper will review the relatively small number of recent patents involving the UNB modulations, and interpret their theoretic foundation and key technology to the best of our knowledge, which may not be as those classical methods a communication engineer accustomed to.
Professor Lenan WU received the B.S. degree in Radar Engineering and M.S. degree in Communication &Electronic Systems in 1982 and 1987, respectively, both from the Nanjing University of Aeronautics and

Abstract: One of the essential divisions of the fast developing field of vehicular technology is the vehicle to infrastructure (V2I) communications. The PHY layer of V2I is implemented by the IEEE 802.11p wireless standard, whose core is the Orthogonal Frequency Division Multiplexing (OFDM) due to its robustness against multipath fading. The recently developed technique called OFDM with Index Modulation (-IM) has a better BER performance than OFDM. A source of error in OFDM-IM is that it uses a subset of the all possible subcarrier activation patterns (SAPs). A latest modification is the OFDM-IMA, referring to OFDM-IM that uses all possible SAPs. In this paper, it is proposed to use OFDM-IMA with subcarrier-level interleaving to replace OFDM in the IEEE 802.11p. Computer simulation results show that the proposed system achieves significant BER improvement with respect to OFDM and OFDM-IM, when tested over standard V2I environments.

Abstract: Breast cancer is the most common cancer among females, and one of the leading causes of death worldwide. Nowadays, the most common method for breast cancer detection is X-ray mammogram screening. Since mammography employs ionizing radiations, the repetition of exposure is not recommended. Aiming to overcome this limitation of the X-ray mammogram screening, a new, low-cost and safe microwave imaging technique was developed in this study. The proposed technique depends on the significant contrast in the dielectric properties of the normal and the tumor tissues. The Computer Simulation Technology Microwave Studio was used to create a model of breast with tumour of 5mm radius. And a circular patch antenna was used in this study. The breast model was placed in front of the antenna, which used as a transmitter as well as a receiver of the microwave. The reflected waves were processed in order to form an image of the tumour. The reconstruction of the reflected waves permits a clear identification of the tumor.

Abstract: In computer science, a formal specification language is defined as a specification language used during systems analysis, requirements analysis and system design to describe a system. This description will be at much higher level than programming, which is used to produce the executable code for a system. Formal specification language provides mathematical representation of the system and expresses the specification in a language whose vocabulary syntax and semantic are properly defined. Today, a variety of formal specification languages are in use some of them are either based on algebraic specification or on model-based specification. In this paper a new specification language called Alneelain specification language is presented. It is based on axiomatic specification. The primary concern in designing the compiler of Alneelain specification language, was with syntax and semantics of the language.

Abstract In the recent years’, image processing is becoming an important field in computer science. Also interaction between human and computer is in increasing rate. Nowadays there are useful applications in measuring the distance to make human life easy and more safety such as alarm systems on cars that make alert sounds when a car becomes too close to any object, and even robots measures distance to make maps of their environments. Those applications normally use one of the sensors laser finder, radar and ultra-sonic. In this paper our concern is to measure the distance using stereo vision and alert user when distance between any objects become less than 30cm. Stereo vision is used because it is cheaper, saves power and easy in implementation. In the experiments the images with 640x480 resolution were tested. Using the distances 50cm, 1m and 1.5m distances, the error was 1%,4% and 12%, respectively.

Abstract: Traffic accidents have recently become a significant terror for all members of the community, their contribution to the cause of death and huge economic losses have become very large, this is due to the violation of the traffic rules and exceeding the speed limit for the road by the drivers. Ambulance and emergency teams face severe difficulties to find their way during the rush hours; this is because the drivers cannot get an early notification to adapt themselves so as to leave these teams pass through. The main objective of this study is to improve the traffic flow to overcome those problems. Some previous studies used a wireless transmission via infrared which considered as a short range. And other used XBee for send the value of the speed only. The methodology used in this study is a design of a communication system between the road and the car to alert and control the speed of the car wirelessly; it consists of a two transceiver module. The device is fixed at Pre-determined position send the speed limit and gives notes about general facilities of the road like the word “school”, “hospital” and “pedestrian crossing”, and “emergency” to alert the drivers that there is incoming ambulance, this alert appear in a form of messages which displayed in the liquid crystal display (LCD). The other device is fixed on the car that received these messages wirelessly from the device that fixed on the road, and then displays it on the LCD. Also controls the vehicle’s speed by using the motor. The result acquisition from this study is the calculation of revolution per minute (rpm) for motor result in 460 rpm therefore the maximum speed of the car is 450kilometers per hour for cars with the radius of the wheel 26 cm. decreasing the revolutions per minute results in decreasing the car speed. The wireless transmission by using Xbee-s1 sends the data at a rate of 250 Kbit/Sec. In conclusion, when using this system it helps in reducing traffic violations and facilitates traffic for emergency vehicles and controlled car speed means safety for lives and possessions. This study recommends adding car to car communication protocol.

Abstract: Mobile networks consist of one or more mobile IP-subnets and is viewed as one connected unit to the internet via one or more Mobile Router (MR).When MR is connecting to the other MR in the other mobile network, it makes a structure known as Nested Mobile Network. In this structure each level of connected router has a Bi-directional tunnel between each pair of MR and its Home Agent (HA) must be established. By this way the message size will increase, because of IP-in-IP header encapsulation. This leads to bad network performance in term of high tunneling overhead. In this paper we investigate on the current route optimization techniques that deal with nested network mobility problem. The main objective of this paper is to develop new a route optimization scheme that enhances the overall network performance by reducing the tunneling overhead, handoff latency, and packet transmission delay. This is accomplished using a hybrid approach between Proxy MIPv6 protocol and SD-TLMR scheme using pre-registration of SD-TLMR of each sub domain in advance with short time update in binding update extensions message format. Analytical model has been used to evaluate the performance analysis and the performance is benchmarked with NEMO protocol, BUL+ and SD-TLMR approaches. The obtained results showed that the proposed hybrid approach has improved the performance of the network when using the packet delay and handoff latency measures compared to the other techniques.

Abstract: In this paper we have designed a DC motor whose speed can be controlled using PID controller and fuzzy logic controller. PID controller requires a mathematical model of the system while fuzzy logic controller base on experience via rule-based knowledge .Design of fuzzy logic controller requires many design decisions , for example rule base and fuzzification. PID controller chooses its parameters base on self-tuning. Fuzzy logic controller uses mamdani system which employs fuzzy sets in consequent part . PID and FLC are investigated with the help of MATLAB / SIMULINK package program simulation. It is founded that FLC is more difficult in design comparing with PID controller, but it has an advance to be more suitable to satisfy non-linear systems.

Abstract: Modeling and simulation of the electric vehicle have attracted increasing attentions to the researchers. Recently, the electric vehicle has emerged as a powerful platform for mitigating energy crisis and reducing environment pollution in the transportation sector. One of the largest barriers is that the electric powered automobile still not competitive with internal combustion engine cars limited by the driving range and battery energy. Therefore, power effectively and energy efficiency are of significance for battery electric automobiles due to the limited stored energy. To achieve improvement in energy saving and better induction motor efficiency within an electric vehicle, a control algorithm such as field oriented control and Space Vector Modulation technique can be used. A first step in modeling an electric vehicle is the selection of suitable parameters and understanding their characteristics. This paper, therefore, presents a study of vehicle parameters based on modeling and simulation of an electric vehicle dynamics when integrated with an induction motor powered by the Li-ion battery using Matlab/Simulink. It also describes a modeling of the electric induction motor based on space vector modulation technique and field oriented control strategy, leading to a design of full electric vehicle prototype. To achieve model goals, simulation results were carried out.

Abstract: Web caching is an important technique to scale the internet. To increase the speed of browsing, Replacement strategies are used. Least Frequency Used (LFU) replacement strategy is one of these web cache replacement strategies. The lack of LFU strategy is that it ignores download latency and size of object and may store obsolete web object indefinitely. A new proposed replacement strategy based on LFU replacement which named Average Least Frequency Used Removal (ALFUR) has been highlighted in this paper. ALFUR can be considered as enhancement of LFU since it overcomes the lacks of LFU.

Abstract: The essential mission requirement of a satellite is the ability to provide a link to transmit information to and from the ground station. In general the communication system of the cube satellite is divided into two subsystems which are telemetry and data subsystem, and beacon subsystem. The telemetry and data subsystem will ensure continuous communication with the ground station. The beacon subsystem is the main part of communication system of the satellite, which provides information about the satellite and its status in a form of continuous wave (CW) which is encoded using Morse code. The beacon subsystem will be used to located the satellite and identify itself for other stations. In ISRASAT1 which is a nano-satellite designed, built and integrated at the Institute of Space Research and Aerospace (ISRA), the beacon subsystem is separated from telemetry and data transmitter and will operate in VHF band at 128 MHz . For the telemetry and data subsystem, the Data Radio transceiver in UHF band at 868 MHz will be used. In this paper, the hardware and software design and implementation of the communication subsystem of ISRASAT1 Cube satellite will be presented.

Abstract: Fourth Generation (4G) systems are expected to operate the global mobile network coverage area. They provide various services for different user types and their requirements. Vertical handovers occur between two layers of cells when a user is switched from one layer to the other. This paper details the influence of network parameters on vertical handover performance in a cell by simulating an overlapped macrocell-microcell environment. It considers handover requests entering a macrocell from a neighbor macrocell and from microcells of a different layer. We calculate various network performance parameters such as mean queue delay, handover dropping probability and channel utilization and compare the handover performance for macrocell and macrocell traffic. Our results demonstrate the influence of total channels, maximum queue size and handover request arrival rate on handover performance. They also show that the performance of each layer is similar in the case were the traffic from each layer is treated with equal priority in the system.
Keywords: 4G systems, handover queue delay, vertical handover.

Abstract: Each day comes, the sector of autopilot and Unmanned vehicles get bigger exponentially; the autopilot design process plays an essential role in the unmanned aerial vehicle (UAV) development process. Autopilot can be designed and developed using different approaches; the most common one is the costly wind tunnel testing, the second and most risky approach is to design based on real fly tests, the third approach which is used in this paper is the Hardware in the loop simulation (HILS). A Hardware in the loop simulation (HILS) platform is designed for unmanned air vehicle (UAV) systems that represent flight attitudes on six degrees of freedom, which reduces risks and costs comparing to the previously mentioned approaches. In this paper a PID-based autopilot is designed, developed, and simulated on Matlab/Simulink Aerosim Blockset Library model of aircraft, the PID-controller algorithm has been implemented using Arduino board which has been connected with the plane model using serial communications. Stability of the system has been achieved by tuning PID parameters in the HILS, desired response and stability has been reached both in Manual and Full autonomous modes, with the aid of Flight Gear simulator for visualizing the aircraft response.

Abstract: Digital audio compression is applied to reduce the data rate required to send audio stream through band limited communication networks, as well as reducing the size of data storage in case of recording audio streams. It is common to apply lossy audio compression algorithms in many applications, which provide higher compression at the expense of the fidelity. MPEG-1&2 Audio Layer III, or MP3, is encoding format for digital audio that uses a form of lossy data compression. It is a regular audio format for consumer audio streaming or storage, and a standard of digital audio compression for the transfer and playback of music on the majority of digital audio players. However, the quality of audio encoding depends on the phonemes of sound that distinguish one word from another in a particular language. Most of speech models applied in audio compression relies on phonemes of English language, rather than those of Arabic language. Therefore, audio encoding of Holly Quran for recording on digital media is highly affected by these differences in the models used. Consequently, serious errors could be produced during the playback of Quran Kareem, which may change the meaning and quality of the output stream. The main objective of this paper is to discuss and evaluate encoding methods for speech in Arabic language accents, focusing on deterioration occurs in producing correct and clear Quran digital audio recording.

Abstract: In brachytherapy treatment of cancer, multiple radioactive seeds are implanted inside the cancer tumor by a surgical needle, and the locations of the seeds are dependent on the accurate placement of the needle at desired position inside the patient body. Therefore needle placement is very important for the effectiveness of brachytherapy treatment. In this work, we propose design of Fuzzy-PID control system for a 5-DOF surgical robot to make the needle follow the desired trajectory to the cancer tumor. Numerical simulation using MALAB is developed to show the effectiveness of the proposed control system. Comparative evaluation with respect to PID controller is presented to validate the controller design. The results presented emphasize that a satisfactory tracking precision could be achieved using the proposed control system.

Abstract : Malaria is a very serious infectious disease caused by a peripheral blood parasite of the genus Plasmodium. Conventional microscopy, which is currently “the gold standard” for the malaria diagnosis has occasionally proved inefficient since it is time consuming and results are difficult to reproduce. As it poses a serious global health problem, automation of the evaluation process is of high importance. In this work, an accurate, rapid and affordable model of malaria diagnosis using stained thin blood smear images was developed. The method makes use of the intensity features of Plasmodium parasites and erythrocytes. Images of infected and non-infected erythrocytes were acquired, pre-processed, relevant features extracted from them and eventually diagnosis was made based on the features extracted from the images. The main part of this work is devoted to the extraction of features from the red blood cell images that could be used for distinguishing between infected and non-infected red blood cells. A set of features based on intensity have been proposed, and the performance of these features on the red blood cell samples from the created database have been evaluated using artificial neural network (ANN) classifiers. The results have shown that these features could be successfully used for malaria detection.

Abstract: The Data Warehouse (DW) design remains a great challenge process for DW designers. As well, so far, there is no strong method to support the process of requirements analysis in DW projects. The literature approaches try to solve this tedious and important issue; however, a lot of these approaches ignore or bypass the requirements elicitation phase; as well, very few works suggest In this paper we propose a method to generate multidimensional schemas from decisional requirements. We elected natural language simplified syntax for expressing decisional/business user’s needs. Our approach is distinct from the existing approaches in that it relies on: i) a natural language based method for eliciting the requirements; ii) a matrix representation to normalize these requirements, and in addition iii) it automates the generation of star schemas relying on eight defined heuristics. A software prototype called SSReq (Star Schemas from Requirements) is developed to demonstrate the feasibility of our proposed approach. A real case study is used to illustrate this approach.

In antenna arrays, the excitation amplitude of the individual elements is one of the major controls that can be used to shape the overall pattern of the antenna. In this paper, 1X10 rectangular patch antenna array is designed and simulated at 9.5 GHZ on specific microwave laminate using uniform, Dolph-Tchebyscheff and Binomial amplitude distributions for specific spacing between elements. The particular spacing are 0.5λ, 0.6λ, 0.8λ and 0.9λ. For each spacing: radiation pattern, beam width, gain, directivity, radiation efficiency and side lobe level are critically investigated and compared for each distribution to justify its usage for radar warning receivers. Simulation is done using ADS 2009 software from Agilent Company. From simulation results, of the three distributions (uniform, binomial, and Dolph-Tchebycheff), a uniform amplitude array yields the smallest half-power beam width. It is followed, in order, by the Dolph-Tchebyscheff and binomial arrays. In contrast, binomial arrays usually possess the smallest side lobes followed, in order, by the Dolph-Tchebycheff and uniform arrays. It is also found that for 0.9λ spacing, Dolph-Tchebyscheff has better efficiency (82.4%), better side lobe level (-32.7 dB) and gain of 16.1 dB with beam width of 7 degrees which makes it the best antenna array solution for RWR systems between the other distributions that have been investigated in this work.

Abstract: Vehicular Ad hoc networks (VANETs) have recently attracted both industry and research communities as emerging technology that strongly support people safety and comfort. However, the lack of permanent infrastructure, high mobility, and serving wide spectrum of applications make VANET susceptible to various types of attacks. This work presents a simple security system that can provide privacy and integrity for exchanging sensitive information in VANET. The developed system efficiently considers the utilization of the available communication bandwidth, the exploitation of the channel properties and the optimization of the speed of the encryption process. The proposed system utilizes the very limited bandwidth of VANET by exchanging small amount of information and employing high speed encryption method. Meanwhile, it provides a high security solution by using avery strong and well known symmetric key encryption method in conjunction with a very efficient key distribution technique. The proposed system utilizes symmetric cryptography systems for securing information transfer owing to their robustness and high speed, while it uses the unique location property of the legitimate vehicles for key generation and distribution. The randomness inherent of the wireless channel is used to extract the secret key. Moreover, SHA-1 algorithm is used to provide information integrity solution.

Abstract: In this research, we propose a particular version of KNN (K Nearest Neighbor) where the similarity between feature vectors is computed considering the similarity among attributes or features as well as one among values. The task of text summarization is viewed into the binary classification task where each paragraph or sentence is classified into the essence or non-essence, and in previous works, improved results are obtained by the proposed version in the text classification and clustering. In this research, we define the similarity which considers both attributes and attribute values, modify the KNN into the version based on the similarity, and use the modified version as the approach to the text summarization task. As the benefits from this research, we may expect the more compact representation of data items and the better performance. Therefore, the goal of this research is to implement the text summarization algorithm which represents data items more compactly and provides the more reliability.

Abstract: Content-based image retrieval (CBIR) is a technique uses visual contents such as color, texture and shape to search images from large scale image databases according to users' interest. In a CBIR, visual image content is represented in form of image features, which are extracted automatically and there is no manual intervention, thus eliminating the dependency on humans in the feature extraction stage. Recent studies in CBIR get the similarity results and retrieve images based on one type of feature which are color, texture or shape. In this study authors proposed a fusion based retrieval model for merging results taken from color and texture image features based different fusion methods. After implementing our proposed retrieval model on Wang image dataset which widely used in CBIR, the results show that Comb MEAN fusion approach has the best and high precision value and outperformed both individual color and texture retrieval model in both top10 and top20 retrieved images.

Abstract: Renewable energy sources gain an importance in recent decades because they are pollution free, easily erectable, and limitless. Solar, wind and hydro are renewable energy sources that are seen as reliable alternatives to conventional energy sources such as oil or natural gas. However, the efficiency and the performance of renewable energy systems are still under development. Among them, Photovoltaic systems are mostly used as they are light, clean and easily installable. Normally PV cells converts sunlight into electricity in the form of dc. A suitable converter is usually needed to convert the dc power into ac power, which is then injecting into the power grid. Inverters can be used to convert the dc into ac for integration of renewable energy sources into the conventional grids. In any PV based system, the inverter is a critical component responsible for the control of electricity flow between the dc source, and loads or grid, in this paper, a comprehensive simulation and implementation of a three phase grid-connected inverter is presented. The control structure of the grid-side inverter is firstly discussed.

Abstract: A discussion thread in an online forum spans multiple pages involving participation of multiple users, which of them replies to some point(s) in the thread. This generates a kind of chaos and information overload. Users often encounter a problem with obtaining the big picture of the content that is distributed among a large number of posts. The solution is to create a concise summary form the thread. In this paper we develop a new approach to address the problem of discussion summarization. Since there are semantic connections between the posts in a thread, this paper defines new relationships types named Cross Post Structure Relationships (CPSR), which could be exploited in scoring sentences. Our approach consists of three phases. In the first phase, we define CPSR five relationships types extracted from thread. In the second phase, we automatically identify these CPSR relations by applying two machine learning techniques, SVM and C4.5. Finally, we generate the summary based on the identified relations. Using the ROUGE evaluation measurement metrics, our model yields better results.

Abstract: To select a suitable Model-Driven Web Engineering (MDWE) methodology to develop web applications, there is the need to specify the features that need to be included in the web site. To evaluate MDWE methodologies in terms of specific features, Quality Evaluation Framework (QuEF) is used to do this task. QuEF can be used to evaluate either a well-established methodology or a new methodology in early stages of development. In this paper, three features namely Model-Driven Engineering (MDE), Web Modeling and Tool Support has been evaluated using QuEF. The comparison has been conducted based on only Functionality quality characteristic of QuEF. It has been applied between NDT as a well-established MDWE methodology and WSDMDA as a new methodology. Results show that NDT is obtained a higher value for MDE and Tool Support features, while WSDMDA is obtained a higher value for Web Modeling feature.

Abstract: In this paper, the clutter estimation problem in the bistatic multiple-input and multiple-output (MIMO) radar system is considered, and a novel compressed sensing (CS)-based model is proposed to describe the clutter by exploiting the clutter sparsity in the angle domain. Then, the CS-based methods are adopted to reconstruct the sparse clutter, and to estimate the clutter scattering coefficients and angles. Additionally, different from the traditionally colocated MIMO radar system with the antenna distance being half of wavelength, we show that the optimal antenna distance in the CS-based radar system can be obtained by minimizing the mutual coherence of the dictionary matrix. Moreover, since the sparse reconstruction performance depends on the geographical positions of the clutter scatterers, an indirect method based on the mutual coherence is proposed to measure the estimation performance, and to optimize the radar parameters. Simulation results show that the CS-based method can estimate the clutter information efficiently, and the better estimation performance is achieved by optimizing the radar parameters.

Abstract: Deep belief network (DBN) has been successfully applied in variety areas such as image recognition and natural language processing. In this paper, we investigate the signal demodulation problems in different types of communication channels. Then, a novel deep belief networks (DBN)-based demodulator is proposed. Since the DBN-based method is just like a black box that can automatically learn how to demodulate the received signals, few manual designs is required in the receiver. Moreover, we also propose a novel mapping method for the communication signals to match the input of DBN. Simulation results with different amounts of training samples and iterations show that the DBN-based demodulator is feasible and efficient.

In order to cope with the huge demands of communications in the network it has been found that it is useful to have multiple receivers served in the same bandwidth during the same time slot. The paper considered vector and matrix normalization for studying the precoding designs of zero-forcing (ZF), matched filter (MF) and maximum ratio transmission (MRT) .The paper also derive the sum rate formulate for every precoding. Depending on the analytical results, we found that in low power MF gives best performance with vector normalization and ZF gives best performance with matrix normalization. Also ZF provides best performance with vector/matrix normalization in high power. The results represented graphically to confirm the analytical results.

Abstract: Signal processing front end for extracting the feature set is an important stage in any speaker recognition system. There are many types of features that are derived differently and have good impact on the recognition rate. This paper uses one of the techniques to extract the feature set from a speech signal known as Mel Frequency Cepstrum Coefficients (MFCCs) to represent the signal parametrically for further processing. The extracted speech features of a speaker is then quantized to number of centroids using the LBG algorithm for clustering. In which a codebook is constructed for each speaker using these centroids. Speakers provide samples of their voices once in a training session and once in a testing session later. Subsequently, the feature coefficients (MFCCs) are calculated in both phases. The speaker is identified according to the minimum quantization distance which is calculated between the centroids of each speaker in the training phase and the MFCCs of individual speaker in the testing phase. The proposed recognition system was designed and implemented using different algorithms in MATLAB. Simulation and experimental results show that the Joint MFCC-and-vector quantization algorithm achieves better performance compared to MFCC and FFT algorithms, in terms of recognition accuracy and text dependency.

Abstract: Defects uncovered during software testing usually consume a considerable amount of the overall project’s budget. Unfortunately, project managers are not well-equipped with techniques to estimate such cost overrun. Moreover, incorporating defects removal process as part of the software testing activities has made the project managers overlook this important cost component during their planning processes. This paper suggested a fuzzy model to estimate the cost of defects removal at the early stages of project planning in terms of the project’s functional size and the experience of the development team.

Abstract: Abstract: A Retransmission Timeout or RTO plays an important role in the TCP protocol, mainly to achieve reliable transmission. In TCP, if the sender sent a segment, no acknowledgement had been received and the RTO timer expired then the sender will assumed that this segment had been lost. This paper proposed another use of the RTO concept in order to secure the TLS session. It calculates a Secure Session RTO or SSRTO which is based on RTO equation between the sender and receiver in a TLS protocol. It is assumed that the man in the middle is in need of the time factor in order to trigger a KCI attack. At the server side, by calculating the time required to start a TLS Handshake Protocol, the TLS Record Protocol will assume that there is an attacker after a preset time has elapsed. The action in this case, is to cut off the session between the sender and the receiver.
Keywords: Retransmission Timeout; Man-in-the-middle attack; TCP protocol; SSL protocol; TLS protocol.

Abstract: One of the aims of communication is to increase the data rate. However, frequency resources are scare and valuable for wireless communication systems. How to use frequency resources efficiently is a significant area which needs the attentions of researchers. Ultra Narrow Band (UNB) has attracted wide attentions since it was proposed. M-ary Position Phase Shift Keying (MPPSK) is one of the UNB modulation modes. The differences in phases of the MPPSK modulated waveform can be transformed into the peaks of the amplitudes through the Impact Filter. Maximum Decision is selected as the decision module of the MPPSK demodulator which needs to search the position where the response of the Impact Filter has a maximum value. As a novel viewing angle, this paper will provide a mathematic explanation for Maximum Decision and prove its validity.

Abstract: During embedded system software development the process of upgrading and downloading the software to the system hardware is fairly easy. Because the platform is not encapsulated on its final production form yet. But when the product is ready to be shipped to the end user, an in-system software upgrade is needed to add a new feature or to fix a bug. In this paper, a custom in-system firmware upgrade approach using SPI will be described for the MSP430 Texas Instrumentations Microcontrollers family.
Keywords: Microcontroller, MSP430, Upgrade, Firmware, In-system Programming.

Abstract: This paper demonstrates the design and simulation of input matching circuit for BLF578XR power transistor working at center frequency of 225 MHZ with bandwidth of more than 50 MHZ. Based on the calculated Q-factor and when using the transistor in push pull mode, the input matching circuit is designed in two stages, the first stage is a balun to match 50 ohm to 12.5 ohm and the other stage is to match 12.5 ohm to the input impedance of BLF578XR. Each stage is designed and simulated separately then both stages are integrated and simulated together. Simulation is done using Microwave office AWR software.
From simulation results, the balun has a phase difference between the two output ports that is approximately 180 degree with good amplitude balance and has -20dB bandwidth larger than 150MHZ. The intermediate matching network has a small insertion loss and very good return loss that is less than -30 dB with -20 dB bandwidth about 110 MHZ. By integration of the balun circuit with the intermediate matching circuit, the resultant input matching circuit has a return loss better than -23dB with -20dB bandwidth about 100 MHZ.

Abstract: Encryption was introduced and implemented in many Database Management Systems (DBMSs) as one of the solutions for securing databases. However, Securing database transactions and data they hold while they are existing in memory or even during their transmission throuh computer networks media should be also given big attention. The core objective of this paper is that to measure the performance of the three classical encryption algorithms: Simple Substitution, Caesar cipher, and Periodic Permutation respectively for encrypting such database transactions and text data they hold. Performances are measured herein in terms of time, memory usage and CPU efforts. The expirement was performed to many categories of transactions, those categories are categorized according to two issues: the size of data that the transactions hold, and the type of transactions itself. This experiment can be a base to enable Database Designers to design algorithms that has the ability to decide which algorithm is optimal according to type of database transaction waiting for processing, as well as size of data that it consists of, and also other computing processing components such as CPU and RAM.

Abstract: In many industries (such as pharmaceuticals, beverage industries, etc.), bottles are required to be filled up with a pre-determined amount of liquid. Implementing systems using relay logic control can cause them to be inflexible. Programmable Logic Controllers – PLCs – are more flexible in automating various processes, since the behavior of the system can be changed without changing the electrical connections, as well as being able to monitor the system undergoing its operation. In this paper, an overflow filler model –filling to certain height – has been controlled using the SIMATIC– Siemens PLC trademark – S7-1200 PLC. It has been monitored through a wireless network to a computer runtime in the Totally Integrated Automation (TIA) portal software, as well as a user webpage in smart devices.

Abstract: Operational amplifiers have been used for interfacing analog signals to microcontrollers units. Due to its random nature, analog signals vary very much, perhaps then exceed the voltage ranges of operation. Chip manufacturers protect their chips by using diode circuits, but those diodes are not intended to normal use. To overcome the signals which may exceed the limit, clamping circuit have been used in this research. The best solution was achieved using a multiplexing circuit implemented using simple switches.

Abstract: This Paper discusses the impact of the series compensation on the voltage profile of the long transmission line, and gives some recommendations and precautions for some expected scenarios of wrong operation that might be taken due to some unknown information about the line condition. Also the paper shows that the compensation of the line should be initially determined to avoid any problem that might be occurred under the abnormal conditions. This paper has illustrated that, series compensation can cause either high or low voltage depending on the load condition of the line and depending also on the setting of the voltage control. In case of the voltage is inadequately controlled at one end of the capacitor, the other side voltage may cause problem. To investigate and study the effect of series compensation on the voltage profile, a simple model of long transmission line has been taken, and for simplicity it has been representing by two pie equivalent model, and the capacitor has been inserted at the middle of the line. SIMULINK / MATLAB has been adopted to simulate the system.

Abstract: The sun is an enormous source of energy which needs to be harvested properly. Solar panels are renewable energy sources that convert the solar energy into electrical energy. But these solar panels’ designs still suffer from low efficiencies. For any Cubesat the Power System Unit is designed to deliver the required energy so as the nano-satellite can achieve it’s desired mission. Thus the input energy for the solar panels and the output energy from the solar cells must be increased.The sun tracking system aims to maximize the input solar energy to the solar panels. This paper aims to study the concept of designing sun tracking solar panels and a maximum power point tracker for the UOKSAT-3 CubeSat which is a 2 units CubeSat with a deployable solar panels. The Cubesat is designed to be orbiting in a sun-synchronous orbit . The paper details the increase in the electrical energy generated by the tracking panels and maintaining it's output at a stable range. The paper also discusses the impact of sun-synchronous orbit on the tracking system and how the tracking frequency is to be proposed. In addition to that, a maximum power point tracker (MPPT) system is proposed to increase the efficiency by manipulating the output voltage and current of these solar panels. This paper studies the design of a maximum power point tracker (MPPT) for the UOKSAT-3 CubeSat. The MPPT system consists of a DC-DC boost converter circuit controlled by microcontroller to determine the desired output. The converter circuit is designed and calculated for different duty cycles according to the solar cells output . The perturb and observe algorithm is used here to track the maximum power delivered from the solar cells. This paper also presents the MPPT’s performance and it’s results to study the change of the input energy using the (MPPT).

Abstract: Abstract—In this work an image processing system was developed to identify malaria parasites in thin blood smears and to classify them into one of the four different species of malaria. Many techniques were implemented in the preprocessing stage to enhance the images. In the first part of the system morphological processing is applied to extract the Red Blood Cells (RBC) from blood images. The developed algorithm picks the suspicious regions and detects the parasites in the images including the overlapped cells. Accordingly, the RBCs are classified into infected and non-infected cells and the number of RBCs in each image is calculated. The second part of the system uses the Normalized Cross-Correlation function to classify the parasite into one of the four species. Compared to manual results, the system achieved 95 % accuracy for diagnosis of malaria and 100% for classifying the parasite into one of its four types.
Keywords: Keywords—Image processing, Malaria parasite detection, Normalized Cross-Correlation. Malaria diagnosis

Abstract: Single electron circuits are proposed for use as a coherent signal source. This paper uses the Monte-Carlo method to investigate the degree of correlation between successive events in long arrays of tunnel junctions. It is shown that longer arrays produce more coherent signals. The fluctuations in the timings of overall train of pulses is attributed to the variations in the actual paths followed by the system during the state transisions. The study recommends the use of circuits where a single path is followed between successive events.

The presentation considers the modelling of multi-machine power networks for the purpose of analysis of transient and steady state stability. The present complexity and ever-increasing size of interconnected power systems have generally led to operating conditions where there are large load angles between generators at remote ends. This reduces limits of synchronous power flow and produces low frequency oscillations [2), and hence leads to a decrease in the over all stability of the system. Because of the continuous increase in demand of electrical power, generators of increased size are continually added to the systems,and units of ratings greater than 1000 MVA are now in service. Generator units of 2000 MVA output are considered as of economical size by 1990s. However, the trend in the parameters of such large conventional machines,also reduces stability.

With the fast development of smart integrate circuit (IC) technology, electrical devices, especially power metal oxide semiconductor (Silicon) filed effect transistors (MOSFET), play more and more important roles in several products and applications, especially in personal computer and cell phone technologies. Thus, new generation smart IC technology needs to provide higher performance product with lower cost. This is not an easy goal to achieve because there are still several problems faced by the device engineers. Two of the most important problems are temperature and electrical stresses encountered by these devices. This talk focuses on power MOSFETs performance and thermal stability, and discusses their long-term reliability in terms of devices degradation before and after the application of accelerated thermal and electrical stresses. There stresses are meant to mimic the accumulated stresses developed on the device as a result of operating the device for a long time under its typical operating conditions. The characterization techniques employed include: SEM, current-voltage temperature and capacitance voltage temperature measurements, charge pumping, and deep level transient spectroscopy.

Professor Lenan WU
Radio spectra in space are close-packed more and more, so its impact of frequency as a valuable resource is increasingly prominent. But whether we can make the transmission bandwidth “ultra narrow” and the data rate even higher, and keep the power transmitted in an acceptable level, what needs surveying is the theory of digital communication and the technology of modulation/demodulation. The Ultra Narrow Band (UNB) modulation is just a sort of transmission technique with efficient-bandwidth and high data rate reported, but its principle and methodology still needs clarifying. So this paper will review the relatively small number of recent patents involving the UNB modulations, and interpret their theoretic foundation and key technology to the best of our knowledge, which may not be as those classical methods a communication engineer accustomed to.
Professor Lenan WU received the B.S. degree in Radar Engineering and M.S. degree in Communication &Electronic Systems in 1982 and 1987, respectively, both from the Nanjing University of Aeronautics and

Abstract: One of the essential divisions of the fast developing field of vehicular technology is the vehicle to infrastructure (V2I) communications. The PHY layer of V2I is implemented by the IEEE 802.11p wireless standard, whose core is the Orthogonal Frequency Division Multiplexing (OFDM) due to its robustness against multipath fading. The recently developed technique called OFDM with Index Modulation (-IM) has a better BER performance than OFDM. A source of error in OFDM-IM is that it uses a subset of the all possible subcarrier activation patterns (SAPs). A latest modification is the OFDM-IMA, referring to OFDM-IM that uses all possible SAPs. In this paper, it is proposed to use OFDM-IMA with subcarrier-level interleaving to replace OFDM in the IEEE 802.11p. Computer simulation results show that the proposed system achieves significant BER improvement with respect to OFDM and OFDM-IM, when tested over standard V2I environments.

Abstract: The on-line walking speed control in human powered exoskeleton systems is a big challenge, the real time translations of human intention to increase or decrease walking speed in maneuverable coupled human exoskeleton systems is still complex field. An adaptive trajectory frequency control algorithm has been developed to guide the exoskeleton’s joint in HUman-powered Augmentation Lower Exoskeleton (HUALEX) within the human wearer intended speed. Based on mismatch of Dual Reaction Force (DRF) sensors, we proposed a new control methodology for walking speed control. Human intention recognition and identification through instrumented footboard and smart shoe is achieved successfully in this work, the new term heel contact time HCT is main feedback for control algorithm. Adaptive Central Pattern Generators (CPGs) used to control joint trajectory frequency, the different walking speeds associated with different functioning of human body CPGs frequency. Experiments on one Degrees of Freedom (1-DOF) platform are demonstrated for walking speed control scheme validation.

Abstract: Breast cancer is the most common cancer among females, and one of the leading causes of death worldwide. Nowadays, the most common method for breast cancer detection is X-ray mammogram screening. Since mammography employs ionizing radiations, the repetition of exposure is not recommended. Aiming to overcome this limitation of the X-ray mammogram screening, a new, low-cost and safe microwave imaging technique was developed in this study. The proposed technique depends on the significant contrast in the dielectric properties of the normal and the tumor tissues. The Computer Simulation Technology Microwave Studio was used to create a model of breast with tumour of 5mm radius. And a circular patch antenna was used in this study. The breast model was placed in front of the antenna, which used as a transmitter as well as a receiver of the microwave. The reflected waves were processed in order to form an image of the tumour. The reconstruction of the reflected waves permits a clear identification of the tumor.
Keywords: Keywords— Microwave Imaging; breast tumor; patch antenna; 2D representation

Abstract : Timetabling is commonly identified by many researchers as NP-complete problem. Such a complex problem is represented as an optimization challenge due to its difficulty in implementing and resource consumption. Many optimization approaches such as swarm intelligence have been implemented in an attempt to find an optimal timetable solution. A huge number of solutions have been presented in literature. These solutions are varies is their optimization algorithm, consequently varies in their objective function strategy, dimensions, efficiency and so forth. However, extra efforts are needed to enhance solutions in this area. Systematic Literature Review method is an efficient tool for understanding, classifying, and finding new trends in the areas searched. Therefore, this paper presents a systematic literature review concerning Swarm Intelligence Optimization techniques needed for solving the timetabling problem. The systematic review includes 143 with a protocol focused on finding primary studies addressing the techniques of swarm intelligence. The reported results showed that techniques such as Firefly algorithm have never been implemented in the area of educational timetabling. Besides, this study has pointed out many new trends in area of optimization-based solution for solving time table problems.

Abstract: In today’s world, wireless communication became the master use in any technology that need transferring of data between devices in far distant places. Some of the previous studies used wireless with global positioning system (GPS) to help paratroops team to know their positions. The problems of paratrooper when they reach the land and they are scattered and can’t find each other’s position quickly. Sometimes paratroops don’t find their equipment that is thrown from the plane to the ground. The main objective of this study is to overcome these problems. In this work every paratrooper must carry a mobile device .The methodology includes three steps first, receiving the position of the paratrooper from GPS ,second displaying the position in the liquid crystal display( LCD) and then send it to the main paratrooper through X-bee wirelessly, third the main paratrooper send all these data to the central computer located in afar place from all paratroops .The central computer displays the paratrooper teams positions in the map continuously while they are moving. The design helps in minimizing the information gathering time, reduce the information transfer time between paratroops and increases safety in the land. In addition to that the new device is less weight and circuit complexity. The study recommends further more analysis and design features added in addition to improve the security using encryption techniques to this positioning and tracking system using Nano circuitry so that the whole device to be in a size of hand watch or less.

Abstract: In computer science, a formal specification language is defined as a specification language used during systems analysis, requirements analysis and system design to describe a system. This description will be at much higher level than programming, which is used to produce the executable code for a system. Formal specification language provides mathematical representation of the system and expresses the specification in a language whose vocabulary syntax and semantic are properly defined. Today, a variety of formal specification languages are in use some of them are either based on algebraic specification or on model-based specification. In this paper a new specification language called Alneelain specification language is presented. It is based on axiomatic specification. The primary concern in designing the compiler of Alneelain specification language, was with syntax and semantics of the language.

Abstract In the recent years’, image processing is becoming an important field in computer science. Also interaction between human and computer is in increasing rate. Nowadays there are useful applications in measuring the distance to make human life easy and more safety such as alarm systems on cars that make alert sounds when a car becomes too close to any object, and even robots measures distance to make maps of their environments. Those applications normally use one of the sensors laser finder, radar and ultra-sonic. In this paper our concern is to measure the distance using stereo vision and alert user when distance between any objects become less than 30cm. Stereo vision is used because it is cheaper, saves power and easy in implementation. In the experiments the images with 640x480 resolution were tested. Using the distances 50cm, 1m and 1.5m distances, the error was 1%,4% and 12%, respectively.

Abstract: Traffic accidents have recently become a significant terror for all members of the community, their contribution to the cause of death and huge economic losses have become very large, this is due to the violation of the traffic rules and exceeding the speed limit for the road by the drivers. Ambulance and emergency teams face severe difficulties to find their way during the rush hours; this is because the drivers cannot get an early notification to adapt themselves so as to leave these teams pass through. The main objective of this study is to improve the traffic flow to overcome those problems. Some previous studies used a wireless transmission via infrared which considered as a short range. And other used XBee for send the value of the speed only. The methodology used in this study is a design of a communication system between the road and the car to alert and control the speed of the car wirelessly; it consists of a two transceiver module. The device is fixed at Pre-determined position send the speed limit and gives notes about general facilities of the road like the word “school”, “hospital” and “pedestrian crossing”, and “emergency” to alert the drivers that there is incoming ambulance, this alert appear in a form of messages which displayed in the liquid crystal display (LCD). The other device is fixed on the car that received these messages wirelessly from the device that fixed on the road, and then displays it on the LCD. Also controls the vehicle’s speed by using the motor. The result acquisition from this study is the calculation of revolution per minute (rpm) for motor result in 460 rpm therefore the maximum speed of the car is 450kilometers per hour for cars with the radius of the wheel 26 cm. decreasing the revolutions per minute results in decreasing the car speed. The wireless transmission by using Xbee-s1 sends the data at a rate of 250 Kbit/Sec. In conclusion, when using this system it helps in reducing traffic violations and facilitates traffic for emergency vehicles and controlled car speed means safety for lives and possessions. This study recommends adding car to car communication protocol.

Abstract: Mobile networks consist of one or more mobile IP-subnets and is viewed as one connected unit to the internet via one or more Mobile Router (MR).When MR is connecting to the other MR in the other mobile network, it makes a structure known as Nested Mobile Network. In this structure each level of connected router has a Bi-directional tunnel between each pair of MR and its Home Agent (HA) must be established. By this way the message size will increase, because of IP-in-IP header encapsulation. This leads to bad network performance in term of high tunneling overhead. In this paper we investigate on the current route optimization techniques that deal with nested network mobility problem. The main objective of this paper is to develop new a route optimization scheme that enhances the overall network performance by reducing the tunneling overhead, handoff latency, and packet transmission delay. This is accomplished using a hybrid approach between Proxy MIPv6 protocol and SD-TLMR scheme using pre-registration of SD-TLMR of each sub domain in advance with short time update in binding update extensions message format. Analytical model has been used to evaluate the performance analysis and the performance is benchmarked with NEMO protocol, BUL+ and SD-TLMR approaches. The obtained results showed that the proposed hybrid approach has improved the performance of the network when using the packet delay and handoff latency measures compared to the other techniques.

Abstract: Wireless sensor network become the most important part in any technology that need to control the environment, because it is enabling interaction between persons or computers and the surrounding environment. One of the new trends that need the wireless sensor network is military applications. The main objective of this research is to design a reliable, inexpensive, small, and easy movement remote weather factors monitoring system for helping and routing the military equipment to oriented and hit the predetermined target accurately without human and material losses. The methodology based on wireless sensor network technology to design of a remote weather factors monitoring system consists of three nodes located in different places to measure all of the surrounding weather factors by using four sensors (temperature and humidity sensor, wind direction sensor, wind speed sensor, and atmosphere pressure sensor), which connected with Arduino then sends this measured factors to a central station via xbee wireless communication module that operate within 2.4 GHz frequency band.

Abstract: Modeling and simulation of the electric vehicle have attracted increasing attentions to the researchers. Recently, the electric vehicle has emerged as a powerful platform for mitigating energy crisis and reducing environment pollution in the transportation sector. One of the largest barriers is that the electric powered automobile still not competitive with internal combustion engine cars limited by the driving range and battery energy. Therefore, power effectively and energy efficiency are of significance for battery electric automobiles due to the limited stored energy. To achieve improvement in energy saving and better induction motor efficiency within an electric vehicle, a control algorithm such as field oriented control and Space Vector Modulation technique can be used. A first step in modeling an electric vehicle is the selection of suitable parameters and understanding their characteristics. This paper, therefore, presents a study of vehicle parameters based on modeling and simulation of an electric vehicle dynamics when integrated with an induction motor powered by the Li-ion battery using Matlab/Simulink. It also describes a modeling of the electric induction motor based on space vector modulation technique and field oriented control strategy, leading to a design of full electric vehicle prototype. To achieve model goals, simulation results were carried out.

Abstract: Web caching is an important technique to scale the internet. To increase the speed of browsing, Replacement strategies are used. Least Frequency Used (LFU) replacement strategy is one of these web cache replacement strategies. The lack of LFU strategy is that it ignores download latency and size of object and may store obsolete web object indefinitely. A new proposed replacement strategy based on LFU replacement which named Average Least Frequency Used Removal (ALFUR) has been highlighted in this paper. ALFUR can be considered as enhancement of LFU since it overcomes the lacks of LFU.

Abstract: The essential mission requirement of a satellite is the ability to provide a link to transmit information to and from the ground station. In general the communication system of the cube satellite is divided into two subsystems which are telemetry and data subsystem, and beacon subsystem. The telemetry and data subsystem will ensure continuous communication with the ground station. The beacon subsystem is the main part of communication system of the satellite, which provides information about the satellite and its status in a form of continuous wave (CW) which is encoded using Morse code. The beacon subsystem will be used to located the satellite and identify itself for other stations. In ISRASAT1 which is a nano-satellite designed, built and integrated at the Institute of Space Research and Aerospace (ISRA), the beacon subsystem is separated from telemetry and data transmitter and will operate in VHF band at 128 MHz . For the telemetry and data subsystem, the Data Radio transceiver in UHF band at 868 MHz will be used. In this paper, the hardware and software design and implementation of the communication subsystem of ISRASAT1 Cube satellite will be presented.

Abstract: Fourth Generation (4G) systems are expected to operate the global mobile network coverage area. They provide various services for different user types and their requirements. Vertical handovers occur between two layers of cells when a user is switched from one layer to the other. This paper details the influence of network parameters on vertical handover performance in a cell by simulating an overlapped macrocell-microcell environment. It considers handover requests entering a macrocell from a neighbor macrocell and from microcells of a different layer. We calculate various network performance parameters such as mean queue delay, handover dropping probability and channel utilization and compare the handover performance for macrocell and macrocell traffic. Our results demonstrate the influence of total channels, maximum queue size and handover request arrival rate on handover performance. They also show that the performance of each layer is similar in the case were the traffic from each layer is treated with equal priority in the system.
Keywords: 4G systems, handover queue delay, vertical handover.

Abstract: Digital audio compression is applied to reduce the data rate required to send audio stream through band limited communication networks, as well as reducing the size of data storage in case of recording audio streams. It is common to apply lossy audio compression algorithms in many applications, which provide higher compression at the expense of the fidelity. MPEG-1&2 Audio Layer III, or MP3, is encoding format for digital audio that uses a form of lossy data compression. It is a regular audio format for consumer audio streaming or storage, and a standard of digital audio compression for the transfer and playback of music on the majority of digital audio players. However, the quality of audio encoding depends on the phonemes of sound that distinguish one word from another in a particular language. Most of speech models applied in audio compression relies on phonemes of English language, rather than those of Arabic language. Therefore, audio encoding of Holly Quran for recording on digital media is highly affected by these differences in the models used. Consequently, serious errors could be produced during the playback of Quran Kareem, which may change the meaning and quality of the output stream. The main objective of this paper is to discuss and evaluate encoding methods for speech in Arabic language accents, focusing on deterioration occurs in producing correct and clear Quran digital audio recording.

Abstract: In brachytherapy treatment of cancer, multiple radioactive seeds are implanted inside the cancer tumor by a surgical needle, and the locations of the seeds are dependent on the accurate placement of the needle at desired position inside the patient body. Therefore needle placement is very important for the effectiveness of brachytherapy treatment. In this work, we propose design of Fuzzy-PID control system for a 5-DOF surgical robot to make the needle follow the desired trajectory to the cancer tumor. Numerical simulation using MALAB is developed to show the effectiveness of the proposed control system. Comparative evaluation with respect to PID controller is presented to validate the controller design. The results presented emphasize that a satisfactory tracking precision could be achieved using the proposed control system.

Abstract : Malaria is a very serious infectious disease caused by a peripheral blood parasite of the genus Plasmodium. Conventional microscopy, which is currently “the gold standard” for the malaria diagnosis has occasionally proved inefficient since it is time consuming and results are difficult to reproduce. As it poses a serious global health problem, automation of the evaluation process is of high importance. In this work, an accurate, rapid and affordable model of malaria diagnosis using stained thin blood smear images was developed. The method makes use of the intensity features of Plasmodium parasites and erythrocytes. Images of infected and non-infected erythrocytes were acquired, pre-processed, relevant features extracted from them and eventually diagnosis was made based on the features extracted from the images. The main part of this work is devoted to the extraction of features from the red blood cell images that could be used for distinguishing between infected and non-infected red blood cells. A set of features based on intensity have been proposed, and the performance of these features on the red blood cell samples from the created database have been evaluated using artificial neural network (ANN) classifiers. The results have shown that these features could be successfully used for malaria detection.

Abstract: The Data Warehouse (DW) design remains a great challenge process for DW designers. As well, so far, there is no strong method to support the process of requirements analysis in DW projects. The literature approaches try to solve this tedious and important issue; however, a lot of these approaches ignore or bypass the requirements elicitation phase; as well, very few works suggest In this paper we propose a method to generate multidimensional schemas from decisional requirements. We elected natural language simplified syntax for expressing decisional/business user’s needs. Our approach is distinct from the existing approaches in that it relies on: i) a natural language based method for eliciting the requirements; ii) a matrix representation to normalize these requirements, and in addition iii) it automates the generation of star schemas relying on eight defined heuristics. A software prototype called SSReq (Star Schemas from Requirements) is developed to demonstrate the feasibility of our proposed approach. A real case study is used to illustrate this approach.

In antenna arrays, the excitation amplitude of the individual elements is one of the major controls that can be used to shape the overall pattern of the antenna. In this paper, 1X10 rectangular patch antenna array is designed and simulated at 9.5 GHZ on specific microwave laminate using uniform, Dolph-Tchebyscheff and Binomial amplitude distributions for specific spacing between elements. The particular spacing are 0.5λ, 0.6λ, 0.8λ and 0.9λ. For each spacing: radiation pattern, beam width, gain, directivity, radiation efficiency and side lobe level are critically investigated and compared for each distribution to justify its usage for radar warning receivers. Simulation is done using ADS 2009 software from Agilent Company. From simulation results, of the three distributions (uniform, binomial, and Dolph-Tchebycheff), a uniform amplitude array yields the smallest half-power beam width. It is followed, in order, by the Dolph-Tchebyscheff and binomial arrays. In contrast, binomial arrays usually possess the smallest side lobes followed, in order, by the Dolph-Tchebycheff and uniform arrays. It is also found that for 0.9λ spacing, Dolph-Tchebyscheff has better efficiency (82.4%), better side lobe level (-32.7 dB) and gain of 16.1 dB with beam width of 7 degrees which makes it the best antenna array solution for RWR systems between the other distributions that have been investigated in this work.

Abstract: Vehicular Ad hoc networks (VANETs) have recently attracted both industry and research communities as emerging technology that strongly support people safety and comfort. However, the lack of permanent infrastructure, high mobility, and serving wide spectrum of applications make VANET susceptible to various types of attacks. This work presents a simple security system that can provide privacy and integrity for exchanging sensitive information in VANET. The developed system efficiently considers the utilization of the available communication bandwidth, the exploitation of the channel properties and the optimization of the speed of the encryption process. The proposed system utilizes the very limited bandwidth of VANET by exchanging small amount of information and employing high speed encryption method. Meanwhile, it provides a high security solution by using avery strong and well known symmetric key encryption method in conjunction with a very efficient key distribution technique. The proposed system utilizes symmetric cryptography systems for securing information transfer owing to their robustness and high speed, while it uses the unique location property of the legitimate vehicles for key generation and distribution. The randomness inherent of the wireless channel is used to extract the secret key. Moreover, SHA-1 algorithm is used to provide information integrity solution.

Abstract: In this research, we propose a particular version of KNN (K Nearest Neighbor) where the similarity between feature vectors is computed considering the similarity among attributes or features as well as one among values. The task of text summarization is viewed into the binary classification task where each paragraph or sentence is classified into the essence or non-essence, and in previous works, improved results are obtained by the proposed version in the text classification and clustering. In this research, we define the similarity which considers both attributes and attribute values, modify the KNN into the version based on the similarity, and use the modified version as the approach to the text summarization task. As the benefits from this research, we may expect the more compact representation of data items and the better performance. Therefore, the goal of this research is to implement the text summarization algorithm which represents data items more compactly and provides the more reliability.

In this research, we define the similarity measure based on both attributes and values, modify the KNN using it, and apply the modified version into the text segmentation task. We may expect more compact representation of data items and improved performance in the text segmentation task as well as other tasks of text mining.

Abstract: Content-based image retrieval (CBIR) is a technique uses visual contents such as color, texture and shape to search images from large scale image databases according to users' interest. In a CBIR, visual image content is represented in form of image features, which are extracted automatically and there is no manual intervention, thus eliminating the dependency on humans in the feature extraction stage. Recent studies in CBIR get the similarity results and retrieve images based on one type of feature which are color, texture or shape. In this study authors proposed a fusion based retrieval model for merging results taken from color and texture image features based different fusion methods. After implementing our proposed retrieval model on Wang image dataset which widely used in CBIR, the results show that Comb MEAN fusion approach has the best and high precision value and outperformed both individual color and texture retrieval model in both top10 and top20 retrieved images.

Abstract: Renewable energy sources gain an importance in recent decades because they are pollution free, easily erectable, and limitless. Solar, wind and hydro are renewable energy sources that are seen as reliable alternatives to conventional energy sources such as oil or natural gas. However, the efficiency and the performance of renewable energy systems are still under development. Among them, Photovoltaic systems are mostly used as they are light, clean and easily installable. Normally PV cells converts sunlight into electricity in the form of dc. A suitable converter is usually needed to convert the dc power into ac power, which is then injecting into the power grid. Inverters can be used to convert the dc into ac for integration of renewable energy sources into the conventional grids. In any PV based system, the inverter is a critical component responsible for the control of electricity flow between the dc source, and loads or grid, in this paper, a comprehensive simulation and implementation of a three phase grid-connected inverter is presented. The control structure of the grid-side inverter is firstly discussed.

Abstract: A discussion thread in an online forum spans multiple pages involving participation of multiple users, which of them replies to some point(s) in the thread. This generates a kind of chaos and information overload. Users often encounter a problem with obtaining the big picture of the content that is distributed among a large number of posts. The solution is to create a concise summary form the thread. In this paper we develop a new approach to address the problem of discussion summarization. Since there are semantic connections between the posts in a thread, this paper defines new relationships types named Cross Post Structure Relationships (CPSR), which could be exploited in scoring sentences. Our approach consists of three phases. In the first phase, we define CPSR five relationships types extracted from thread. In the second phase, we automatically identify these CPSR relations by applying two machine learning techniques, SVM and C4.5. Finally, we generate the summary based on the identified relations. Using the ROUGE evaluation measurement metrics, our model yields better results.

Abstract: To select a suitable Model-Driven Web Engineering (MDWE) methodology to develop web applications, there is the need to specify the features that need to be included in the web site. To evaluate MDWE methodologies in terms of specific features, Quality Evaluation Framework (QuEF) is used to do this task. QuEF can be used to evaluate either a well-established methodology or a new methodology in early stages of development. In this paper, three features namely Model-Driven Engineering (MDE), Web Modeling and Tool Support has been evaluated using QuEF. The comparison has been conducted based on only Functionality quality characteristic of QuEF. It has been applied between NDT as a well-established MDWE methodology and WSDMDA as a new methodology. Results show that NDT is obtained a higher value for MDE and Tool Support features, while WSDMDA is obtained a higher value for Web Modeling feature.

Abstract: In this paper, the clutter estimation problem in the bistatic multiple-input and multiple-output (MIMO) radar system is considered, and a novel compressed sensing (CS)-based model is proposed to describe the clutter by exploiting the clutter sparsity in the angle domain. Then, the CS-based methods are adopted to reconstruct the sparse clutter, and to estimate the clutter scattering coefficients and angles. Additionally, different from the traditionally colocated MIMO radar system with the antenna distance being half of wavelength, we show that the optimal antenna distance in the CS-based radar system can be obtained by minimizing the mutual coherence of the dictionary matrix. Moreover, since the sparse reconstruction performance depends on the geographical positions of the clutter scatterers, an indirect method based on the mutual coherence is proposed to measure the estimation performance, and to optimize the radar parameters. Simulation results show that the CS-based method can estimate the clutter information efficiently, and the better estimation performance is achieved by optimizing the radar parameters.

Abstract: Abstract- Air Data Computer (ADC) is an electronics device computes air data flight parameters. The objective of this paper is to analyze, simulate, and propose hardware implementation module for the Air Data Computer. Simulation of ADC model has been faced by two problems. The first one was to choose true values of dynamic temperature because it depends on flight altitude and airspeed. The second problem is that Mach number equation for Mach greater than one is implicit equation. This work propose modified model to avoid the first problem, and using numerical methods to solve the implicitly of Mach number equation.

Abstract: Deep belief network (DBN) has been successfully applied in variety areas such as image recognition and natural language processing. In this paper, we investigate the signal demodulation problems in different types of communication channels. Then, a novel deep belief networks (DBN)-based demodulator is proposed. Since the DBN-based method is just like a black box that can automatically learn how to demodulate the received signals, few manual designs is required in the receiver. Moreover, we also propose a novel mapping method for the communication signals to match the input of DBN. Simulation results with different amounts of training samples and iterations show that the DBN-based demodulator is feasible and efficient.

Abstract: The hopeful technique Massive MIMO is provided to increase the data rates of mobile communication, by arranging antenna to hundreds of the base stations which is the most promising solution for the fifth generation of cellular communication network. In order to cope with the huge demands of communications in the network it has been found that it is useful to have multiple receivers served in the same bandwidth during the same time slot. The paper considered vector and matrix normalization for studying the precoding designs of zero-forcing (ZF), matched filter (MF) and maximum ratio transmission (MRT) .The paper also derive the sum rate formulate for every precoding. Depending on the analytical results, we found that in low power MF gives best performance with vector normalization and ZF gives best performance with matrix normalization. Also ZF provides best performance with vector/matrix normalization in high power. The results represented graphically to confirm the analytical results.

Abstract: Signal processing front end for extracting the feature set is an important stage in any speaker recognition system. There are many types of features that are derived differently and have good impact on the recognition rate. This paper uses one of the techniques to extract the feature set from a speech signal known as Mel Frequency Cepstrum Coefficients (MFCCs) to represent the signal parametrically for further processing. The extracted speech features of a speaker is then quantized to number of centroids using the LBG algorithm for clustering. In which a codebook is constructed for each speaker using these centroids. Speakers provide samples of their voices once in a training session and once in a testing session later. Subsequently, the feature coefficients (MFCCs) are calculated in both phases. The speaker is identified according to the minimum quantization distance which is calculated between the centroids of each speaker in the training phase and the MFCCs of individual speaker in the testing phase. The proposed recognition system was designed and implemented using different algorithms in MATLAB. Simulation and experimental results show that the Joint MFCC-and-vector quantization algorithm achieves better performance compared to MFCC and FFT algorithms, in terms of recognition accuracy and text dependency.

Abstract: Defects uncovered during software testing usually consume a considerable amount of the overall project’s budget. Unfortunately, project managers are not well-equipped with techniques to estimate such cost overrun. Moreover, incorporating defects removal process as part of the software testing activities has made the project managers overlook this important cost component during their planning processes. This paper suggested a fuzzy model to estimate the cost of defects removal at the early stages of project planning in terms of the project’s functional size and the experience of the development team.

Abstract: Abstract: A Retransmission Timeout or RTO plays an important role in the TCP protocol, mainly to achieve reliable transmission. In TCP, if the sender sent a segment, no acknowledgement had been received and the RTO timer expired then the sender will assumed that this segment had been lost. This paper proposed another use of the RTO concept in order to secure the TLS session. It calculates a Secure Session RTO or SSRTO which is based on RTO equation between the sender and receiver in a TLS protocol. It is assumed that the man in the middle is in need of the time factor in order to trigger a KCI attack. At the server side, by calculating the time required to start a TLS Handshake Protocol, the TLS Record Protocol will assume that there is an attacker after a preset time has elapsed. The action in this case, is to cut off the session between the sender and the receiver.

Abstract: One of the aims of communication is to increase the data rate. However, frequency resources are scare and valuable for wireless communication systems. How to use frequency resources efficiently is a significant area which needs the attentions of researchers. Ultra Narrow Band (UNB) has attracted wide attentions since it was proposed. M-ary Position Phase Shift Keying (MPPSK) is one of the UNB modulation modes. The differences in phases of the MPPSK modulated waveform can be transformed into the peaks of the amplitudes through the Impact Filter. Maximum Decision is selected as the decision module of the MPPSK demodulator which needs to search the position where the response of the Impact Filter has a maximum value. As a novel viewing angle, this paper will provide a mathematic explanation for Maximum Decision and prove its validity.

Abstract: This paper demonstrates the design and simulation of input matching circuit for BLF578XR power transistor working at center frequency of 225 MHZ with bandwidth of more than 50 MHZ. Based on the calculated Q-factor and when using the transistor in push pull mode, the input matching circuit is designed in two stages, the first stage is a balun to match 50 ohm to 12.5 ohm and the other stage is to match 12.5 ohm to the input impedance of BLF578XR. Each stage is designed and simulated separately then both stages are integrated and simulated together. Simulation is done using Microwave office AWR software.
From simulation results, the balun has a phase difference between the two output ports that is approximately 180 degree with good amplitude balance and has -20dB bandwidth larger than 150MHZ. The intermediate matching network has a small insertion loss and very good return loss that is less than -30 dB with -20 dB bandwidth about 110 MHZ. By integration of the balun circuit with the intermediate matching circuit, the resultant input matching circuit has a return loss better than -23dB with -20dB bandwidth about 100 MHZ.

Abstract: Encryption was introduced and implemented in many Database Management Systems (DBMSs) as one of the solutions for securing databases. However, Securing database transactions and data they hold while they are existing in memory or even during their transmission throuh computer networks media should be also given big attention. The core objective of this paper is that to measure the performance of the three classical encryption algorithms: Simple Substitution, Caesar cipher, and Periodic Permutation respectively for encrypting such database transactions and text data they hold. Performances are measured herein in terms of time, memory usage and CPU efforts. The expirement was performed to many categories of transactions, those categories are categorized according to two issues: the size of data that the transactions hold, and the type of transactions itself. This experiment can be a base to enable Database Designers to design algorithms that has the ability to decide which algorithm is optimal according to type of database transaction waiting for processing, as well as size of data that it consists of, and also other computing processing components such as CPU and RAM.

Abstract: In many industries (such as pharmaceuticals, beverage industries, etc.), bottles are required to be filled up with a pre-determined amount of liquid. Implementing systems using relay logic control can cause them to be inflexible. Programmable Logic Controllers – PLCs – are more flexible in automating various processes, since the behavior of the system can be changed without changing the electrical connections, as well as being able to monitor the system undergoing its operation. In this paper, an overflow filler model –filling to certain height – has been controlled using the SIMATIC– Siemens PLC trademark – S7-1200 PLC. It has been monitored through a wireless network to a computer runtime in the Totally Integrated Automation (TIA) portal software, as well as a user webpage in smart devices.

Abstract: Operational amplifiers have been used for interfacing analog signals to microcontrollers units. Due to its random nature, analog signals vary very much, perhaps then exceed the voltage ranges of operation. Chip manufacturers protect their chips by using diode circuits, but those diodes are not intended to normal use. To overcome the signals which may exceed the limit, clamping circuit have been used in this research. The best solution was achieved using a multiplexing circuit implemented using simple switches.

Abstract: This Paper discusses the impact of the series compensation on the voltage profile of the long transmission line, and gives some recommendations and precautions for some expected scenarios of wrong operation that might be taken due to some unknown information about the line condition. Also the paper shows that the compensation of the line should be initially determined to avoid any problem that might be occurred under the abnormal conditions. This paper has illustrated that, series compensation can cause either high or low voltage depending on the load condition of the line and depending also on the setting of the voltage control. In case of the voltage is inadequately controlled at one end of the capacitor, the other side voltage may cause problem. To investigate and study the effect of series compensation on the voltage profile, a simple model of long transmission line has been taken, and for simplicity it has been representing by two pie equivalent model, and the capacitor has been inserted at the middle of the line. SIMULINK / MATLAB has been adopted to simulate the system.

Abstract: The sun is an enormous source of energy which needs to be harvested properly. Solar panels are renewable energy sources that convert the solar energy into electrical energy. But these solar panels’ designs still suffer from low efficiencies. For any Cubesat the Power System Unit is designed to deliver the required energy so as the nano-satellite can achieve it’s desired mission. Thus the input energy for the solar panels and the output energy from the solar cells must be increased.The sun tracking system aims to maximize the input solar energy to the solar panels. This paper aims to study the concept of designing sun tracking solar panels and a maximum power point tracker for the UOKSAT-3 CubeSat which is a 2 units CubeSat with a deployable solar panels. The Cubesat is designed to be orbiting in a sun-synchronous orbit . The paper details the increase in the electrical energy generated by the tracking panels and maintaining it's output at a stable range. The paper also discusses the impact of sun-synchronous orbit on the tracking system and how the tracking frequency is to be proposed. In addition to that, a maximum power point tracker (MPPT) system is proposed to increase the efficiency by manipulating the output voltage and current of these solar panels. This paper studies the design of a maximum power point tracker (MPPT) for the UOKSAT-3 CubeSat. The MPPT system consists of a DC-DC boost converter circuit controlled by microcontroller to determine the desired output. The converter circuit is designed and calculated for different duty cycles according to the solar cells output . The perturb and observe algorithm is used here to track the maximum power delivered from the solar cells.

Abstract: Abstract—In this work an image processing system was developed to identify malaria parasites in thin blood smears and to classify them into one of the four different species of malaria. Many techniques were implemented in the preprocessing stage to enhance the images. In the first part of the system morphological processing is applied to extract the Red Blood Cells (RBC) from blood images. The developed algorithm picks the suspicious regions and detects the parasites in the images including the overlapped cells. Accordingly, the RBCs are classified into infected and non-infected cells and the number of RBCs in each image is calculated. The second part of the system uses the Normalized Cross-Correlation function to classify the parasite into one of the four species. Compared to manual results, the system achieved 95 % accuracy for diagnosis of malaria and 100% for classifying the parasite into one of its four types.

Abstract: Single electron circuits are proposed for use as a coherent signal source. This paper uses the Monte-Carlo method to investigate the degree of correlation between successive events in long arrays of tunnel junctions. It is shown that longer arrays produce more coherent signals. The fluctuations in the timings of overall train of pulses is attributed to the variations in the actual paths followed by the system during the state transisions. The study recommends the use of circuits where a single path is followed between successive events.
