Abstract: Design an Ultra-Wideband antenna that rejects all frequency bands that cause interference as WLAN) for IEEE 802.11a coverage the (5.15– 5.35) GHz and the (5.725 –5.825) GHz bands, WiMAX coverage in (3.3 –3.6) GHz and C-band operating in (3.7–4.2) GHz. The goal of this research is to reduce the problem of interference in bands in communication systems by using the current distribution techniques, by adding notch such as rectangular slit cutting and side slitting on the patch are used to reduce large bandwidths and rejected unwanted bands. It focuses on the design, simulation, and fabrication analysis for UWB assigned applications with, low cost, large bandwidth, high data rate, and appropriate radiation pattern. These studies were performed using the "Computer Simulation Technology (CST)" software package and yielded the best design dimensions for the proposed antennas. Four antennas are proposed, the first type is circular patch structure with dimensions optimized (36.5×35×1.6) mm3, the notch band consisting of two rectangular slit on the radiate patch to reject frequency range (3.3-3.7) GHz. The second antenna is designed as a tree shape by substrate dimensions (24×24×1.6) mm3, the rejecting band with center (4.7 GHz). The third type is designing an elliptical patch antenna with dimensions 40×40×1.6 mm3 , Rectangular slots are used to achieve a rectangular notch in WMAX (3.1-3.8) GHz and X-band (7.1-7.8) GHz. The fourth design consists of a rectangular patch size is (50 × 48 × 1.6) mm3, two symmetrical slots in the patch that produces a single band frequency (8.3GHz) to prevent interference with all other frequency bands. All designs achieved antenna design requirements, such as the Voltage Standing Wave Ratio (VSWR) less than two, good gain, small size, and low dispersions. ,

Abstract: Widespread wireless communications system in the last few years, leads people to ask many questions about the advantages and disadvantages of those systems, especially about electromagnetic waves pollution and their effect on human health.The mobile device is frequently used by the general public from adult to child, one of the main sources of electromagnetic waves and very close to the human head. Therefore the focus of this research on the impact of electromagnetic waves from mobile to human health by measuring the Specific Absorption Rate (SAR), at the human head and the hand through SEMCAD - X that uses the Finite Different Time Domain (FDTD). SAR computation uses (FDTD) in the way the limited space of time, to calculate the specific absorption rate. The results have been compared with standards averaged over any 1 g of tissue and averaged over any 10 g of tissue. It didn't exceed the applicable standard.This work evaluates specific absorption rate (SAR) at different ages of three people. Firstly, old man, who was estimated to head 100% size of header used in the program SEMCAD - X. Secondly Adult man was estimated his head by 85% size of header used in program, and finally the child who was estimated his head by 65% size of header used in the program SEMCAD - X, the design hand has been used with all cases.The design of the mobile phone software works in four different packages of frequencies; the packets are the center frequencies 900MHz 1800MHz, 2100MHz and 2400MHz, when increased frequency the SAR increased but in the some state and frequency decreasing.The Evaluation of SAR in the head and the hand of the user device and the generic phone, the highest value of SAR decreases with increasing distance between the generic phone and the user's head and reducing the proportion was 50% for the old man, 40% for adult man and 35% for child. It can be noted that the angle of the rotation of the various frequencies is not fixed, while the ratio approximately is 25% for each angle of rotation.Also, it can be noted that for fixed frequency, the input power is increased to a double and the SAR have been used increased almost to a double.The different positions show that the methods of holding generic phone have a significant impact on the value of SAR. Therefore, the value of SAR can be reduced into 90% when using the correct method.The evaluation of SAR in these cases shows their influence on children and it was much greater than the adult human or old human by parentage 40% old man and 35% adult man.

Abstract: يتناول هذا البحث مشكلة تمييز الحروف العربية المعزولة المكتوبة بخط اليد باستخدام الشبكات العصبية. ان نظام تمييز الحروف العربية المقترح يتكون من ثلاث مراحل وهي : مرحلة مسح صور الحروف العربية ثم مرحلة معالجة الصور واخيرا مرحلة التدريب والتصنيف.ان المرحلة الاخ | This thesis presents an algorithm for recognition of an off - line isolated handwritten Arabic letters using neural networks.The handwritten recognition system present in this work consists of three modules : - 1 - Arabic letter scanning module 2 - Arabic letter preprocessing module 3 - Learning and recognition module.The proposed neural network in the third module is trained in two stages : The first stage employs Self - Organizing Map learning algorithm for clustering the input pattern, which are based on a database of 196 letters collected from 7 independent persons.In the second stage each of the similar output cluster is considered as a subnet introduced to neural network trained by Back - propagation learning algorithm for classification. Several networks architecture are designed in the second stage using 1 - hidden and 2 - hidden layers with 5 and 28 output nodes in the output layer with different number of hidden nodes and learning rate.To examine the efficiency of the system a database of 196 letters collected from other 7 independent persons are used, (in order to test the ability of the trained network to generalize). The results show that clustering the input pattern, using 1 - hidden layer and 28 nodes in output layer improve the network performance. The system was implemented using (IBM - PC) of type Pentium 3.The programming language used to design the system was c++ version 5.02.

Abstract: In this thesis, a proposed control strategy is presented to improve the performance of the PWM boost type rectifier when operating under different supply voltage conditions (balanced, unbalanced, and distorted three - phase supply voltages). The proposed control strategy is classified into two parts, the first part is voltage controller and the second part is current controller. In the voltage controller, Repetitive Controller (RC) is used to reduce the even order harmonics in the regulated output dc voltage (5.62V (P.P.)) so small output capacitor (480µF) is used instead of large capacitor (920µF) that is used with the conventional controller (PI controller connected in series with a LPF). RC also reduces the even order harmonics (0.014A (P.P)) which appears in the reflected dc current (IMAX), this leads to reduce the odd order harmonics (0.01A) which appears in the input currents. While in the current controller, enhanced Phase Locked Loop (EPLL) technique is used to obtain sinusoidal and balanced three phases, to construct the reference currents, which are in phase with the fundamental supply voltages Therefore, the supply - side power factor is kept close to unity (0.9036 for extremely distorting case). As a result the calculations of the reference currents in the proposed control strategy does not require Clarke or Park transformations, the same for the calculations of the positive or negative sequence components. A proportional controller is used to give excellent tracking between the line and the reference currents. Using this approach makes the control strategy easy to understand and also it saves calculation time of the control algorithms if implements in real time. The complete system with the proposed control strategy is simulated using Matlab/Simulink (Version 2012). The obtained results for the complete system using repetitive voltage controller are compared to the results of the system with using the conventional voltage controller. The results with the repetitive controller show better responses and stable operation in the steady state under different input voltage conditions, as well as in the transient response under different disturbances.

Abstract: Solar energy systems based on photovoltaic (PV) cells have attracted considerable interest in recent years due to their abilities of clear and seemingly limitless generated energy. Solar energy systems based on microinverter architectures are earning in publicity as they are less prone to shading and PV cell malfunction since each PV panel in the system has its own low power inverter.In this thesis two alternative modes of operation for the current source flyback microinverter are suggested : the discontinuous conduction mode (DCM), where a constant switching frequency (CSF) control method is applied, and the boundary conduction mode (BCM) between continuous conduction mode (CCM) and DCM, where a variable switching frequency (VSF) control method is used. These two control methods are analytically studied and compared in order to establish their advantages as well as their suitability for the development of an inverter for grid - connected PV applications.An optimum design methodology is developed, aiming for an inverter with the smallest possible volume for the maximum power transfer to the public grid and wide PV energy exploitation. The main advantages of the current source flyback microinverter are very high power density and high efficiency due to its simple structure, as well as high power factorregulation. The design and control methodology are validated by Powersimulation software (PSIM) and a laboratory hardware prototype is buildusing analogue and digital devices.The microcontroller type (PIC - 18F45K22) is used to implement perturb and observe (P&O) maximum power point tracking (MPPT) algorithm, and C language is used for programing the microcontroller. The simulation and experimental results are obtained to verify the proposed flyback microinverter.
