Abstract: Routers are intelligent devices that make connection between different networks possible. In addition, routers can perform several functions, including filtration and selection of the best path of packets movement. Routers must be configured efficiently in order to perform the above functions. In literature, two approaches have been distinguished for the configuration, namely; text mode and graphical mode approach. The present work is analyzing these two approaches and defines precisely their advantages and limitations. As a result of this analysis, a new approach is proposed in this thesis which eliminates the limitations. The work proposes a graphical interface which is executed on a desktop (or laptop) PC. The user defines the configuration parameters through a program which transfers these parameters to the router by console port instead of Ethernet port. These parameters are then saved on Non Volatile Random Access Memory. The proposed graphical interface is implemented by standard lab consisted of two routers. The implementation shows that the time of configuration can be reduced to 70% of the text mode approach, and overcome the trouble of the old graphical interface.

Abstract: تم تطوير تكنولوجيا الراديو عبر الالياف منذ اواخر القرن العشرين، وتم استخدامها في مجموعة من التطبيقات لانظمة الاتصالات ويعتبر الراديو عبر الالياف هو الجيل المقبل من انظمة الاتصالات لما يمتاز به من العديد من المزايا مقارنة مع النظام التقليدي مع توهين منخفض | Radio - over - Fiber (RoF) technology has been developed since the late 20th century and has been used efficiently in a range of applications for communication systems. Radio over fiber system is the next generation of communication systems because it has many advantages compared with conventional system with low attenuation, enormous bandwidth of optical fiber, and extension of existing coverage and capacity. RoF system refers to the radio signals which are modulated with optical signal and transmitted over optical fiber link from Central Office (CO) to the Remote Nodes (RNs).In this work, several RoF systems have been designed and simulated with different modulation techniques using commercial software package called “Optisystem v.12”. Furthermore, these systems were compared with each other to check for better performance. These systems are presented as follows : The first system is RoF with Quadrature Phase Shift Keying (QPSK), 16 - Quadrature Amplitude Modulation (16 - QAM), and 64 - QAM schemes with and without OFDM technique. The simulation results of this system show that the Signal to Noise Ratio (SNR) for 64 - QAM - OFDM higher than SNR for QPSK, 4 - QAM and 16 - QAM with OFDM at 10 - 9 symbol error, after 50 km of SMF length without any amplification or compensation techniques. In addition, also SNR for 64 - QAM - OFDM higher than SNR for other techniques in this work after 160 km of fiber length.The second system is the RoF with QPSK and 16 - QAM schemes with Digital Signal Processing (DSP) unit in the receiver side. The simulation results of this system show that the Error Vector Magnitude (EVM) for QPSK scheme with DSP unit is 14.5% and 85.5% without DSP unit after 50 km of fiber length. Furthermore, the EVM for 16 - QAM with DSP unit is 7.5%, but the EVM for the same system without DSP unit is 91%. In addition, the EVM for QPSK with DSP equal to 11.5%, but the EVM for 16 - QAM with DSP equal to 9% after 160 km of fiber length.The third system is RoF system with two multiplexing techniques, 8×10 Gbps WDM - RoF system and 4×5 Gbps SCM - RoF system, have been simulated with 4 - QAM - OFDM, 16 - QAM - OFDM and 64 - QAM - OFDM schemes. The fourth system was to combine the techniques of wavelength division multiplexing (WDM) and subcarrier multiplexing (SCM) to increase the capacity of the system by 20×8 Gbps data rate. The simulation results show that the SCM - WDM - RoF with 64 - QAM gives high SNR compared with SCM - WDM - RoF system with other modulation schemes which have been used in this work.

Abstract: ان عمل وتركيب نظام التوزيع يتغير مع اضافة وحدات التوليد الموزع (DG )، حيث انها تؤثر على خسائر القدرة، الاستقرارية، الفولطية، جودة الطاقة وكميات اخرى، لذلك اختيار الموقع الامثل والحجم وعدد وحدات التوليد الموزع (DG ) ضروري لتجنب التاثيرات السلبية على نظا | The operation and structure of distribution system are changing with the integration of distributed generation (DG), where the DG may have effect on power losses, stability, voltage profile, power quality and other quantities, therefore the optimization of location , size and number of DG are necessary to avoid the negative impacts on electric power system.In this work, the Particle Swarm Optimization (PSO) technique is used to find the optimal number and locations of DG in order to minimize the active power losses. The thermal limit of transmission lines and transformers was studied in cases , with DG and without DG, to detect the lines or transformers which exceed the limit in order to processed it. The voltage stability of distribution network has been investigated, using L index (which aims to detect the vulnerable load buses of an electrical power system). Also the rotor angle transient stability of DG units has been calculated to specify the critical clearing time (CCT) of each circuit breaker in distribution network when one of transmission lines is exposed to three phase to ground fault. The developed algorithm has been verified using two test systems IEEE 33 - bus distribution system and the WSCC 9 - bus test system, furthermore applied to a part of Iraqi distribution network (Al - Najaf Al - Ashraf distribution network). Two softwares are used in this work , the first is Matlab R2013a for implementation of the PSO and voltage stability algorithms while the second software is Power World Simulator 15 for implementation of the thermal limit of transmission lines and transformers, and rotor angle transient stability of DG units.DG contributed significantly to reduce the power losses in Al - Najaf Al - Ashraf distribution network, where there is a reduction by about 96% in active losses. Also DG processed the overload of large substations and the stability of buses in the network.

Abstract: Solar cells are considered a promising technology and renewable, in view of increasing in the electro - optical energy. The continual enhancement in solar cell efficiency by searching for new concepts and techniques, which should grow since it is considered as one of the important sources of energy of the future.This work introduces a type of solar cells that employs photosensitive organic dye. These cells use thin membrane of Titanium dioxide material as nanoparticles covered by an organic dye, which absorbs solar energy (like the chlorophyll in green leaves) to be converted into electrons that are injected into the Titanium dioxide layer, which serves as electron collector. In addition, it has an electrolyte solution to compensate for the electrons lost by the organic dye molecules.The cell's positive terminal was prepared from the deposition of a thin membrane of Titanium dioxide, of 22 micrometer thickness on a conductive glass electrode , followed by heat treatment at 450? for 30 minutes. Three organic dyes were used, two of (Cherry juice mixed with Hibiscus and the Berries juice) which were natural dyes, and the other synthetic, the "Eosin" as an industrial dye. Small quantities of Iodine and Potassium Iodide were dissolved in Ethyl Alcohol of 99.9% concentration in order to prepare the electrolyte solution. As to the negative terminal, it was prepared from the deposition of a graphite layer, used in pencils, onto a conducting glass electrode. The final stage involved the assembly of the different prepared cell components and tested.The equipment used in this work included spectrum analyzer for provision of absorption spectra for the three dyes.The cells have been tested by exposure to light of 100W/cm2 to obtain I - V characteristic curve and the greatest current is obtained with the Cherries and Hibiscus cell was 6.205 mA/cm2 and the maximum voltage 0.569 V. As to the Berries dye cell, the maximum current is found 4.35 mA / cm2 and its maximum voltage 0.607 V. The maximum current and voltage for the Eosin dye cell are found to be 1.32 mA/ cm2 and 0.651V.The conversion efficiency for the Cherry and Hibiscus dye cell is found to be 1.9%, the Berries dye cell 1.5% and for the Eosin dye 0.5%.

Abstract: الهجمات عن طريق تزوير المتحكم بالوصول الى الوسط (MAC) تشمل تغيير المهاجم العنوان المصنعي للMAC الى اي قيمة اخرى. هجمات التزوير للMAC في شبكات الواي فاي بسيطة بسبب سهولة الوصول الى الادوات التي تزور الMAC على الانترنت مثل MAC Makeup وبالاضافة الى ذلك نستطي | Medium Access Control (MAC) spoofing attacks relate to an attacker altering the manufacturer assigned MAC address to any other value. MAC spoofing attacks in WiFi network are simple because of the ease of access to the tools of the MAC fraud on the Internet like MAC Makeup, and in addition to that the MAC address can be changed manually without software. MAC spoofing attacks are considered one of the most intensive attacks in the WiFi network; as result for that, many MAC spoofing detection systems were built, each of which comes with its strength and weak points. This thesis logically identifies and recognizes the weak points and masquerading paths that penetrate the up - to - date existing detection systems. Then the most effective features of the existing detection systems are extracted, modified and combined together to develop more powerful detection system.Sequence Number with Rate and Signal Strength detection method (SN - R - SS) consists from three phases. First phase is Window Sequence Numbers; to detect suspicious spoofed frames in the network. Second phase is Transmission Rate Analysis; to reduce the amount of the suspicious spoofed frames that are generated from the first phase. Finally, the third phase is Received Signal Strength; this phase is decisive phase because it decides whether the suspicious spoofed frames are spoofed or not. Commview for WiFi network monitor and analyzer is used to capturing frames from the radio channals. Matlab language is used to implement various computational and mathematical relations in SN - R - SS. This detection method does not work in a real time because this method needs a lot of computation.

Abstract: التحكم المباشر لعزم الدوران هو اسلوب التحكم المستخدم في انظمة محرك التيار المتناوب للحصول على سيطرة عزم دوران عالية الاداء. محرك DTC التقليدية يحتوي على زوج من الـ ( hysteresis comparators)، حساب الفيض وعزم الدوران وجدول اختيارالـ ( voltage vector). يت | Direct Torque Control (DTC) is a control technique used in AC drive systems to obtain high performance torque control. The conventional DTC drive contains a pair of hysteresis comparators, a flux and torque estimator and a voltage vector selection table. The torque and flux are controlled simultaneously by applying suitable voltage vectors, and by limiting these quantities within their hysteresis bands, de - coupled control of torque and flux can be achieved. Conventional DTC drives utilizing hysteresis comparators suffer from high torque ripple and variable switching frequency. Several techniques have been developed to improve the torque performance. In this thesis, Proportional - Integral (PI) controller has been presented to improve the system performance which gives better torque and flux response and also reduces the undesirable torque ripple. The most common solution to high torque ripple and variable switching frequency is to use the space vector pulse width modulation (SV - PWM) that depends on the reference torque and flux. The reference voltage vector is then realized by using a voltage vector modulator.The conventional DTC and DTC with PI controller are implemented using Xilinx System Generator (XSG) for MATLAB/Simulink environment through Xilinx blocksets. The design was achieved in VHDL, based on a MATLAB/Simulink simulation model. The Hardware - in - the - Loop (HIL) method is used to verify the functionality of the Xilinx FPGA estimator. The results are obtained and compared with MATLAB/ Simulink results considering the implementation of the proposed model on the Xilinx NEXYS2 Spartan 3E1200 FG320 Kit. The simulations of the DTC - SVPWM were carried out using MATLAB/ Simulink simulation package. The design, implementation and simulation of the overall drive system is performed using MATLAB/Simulink program version 7.13.0.564 (R2011ba) and Xilinx ISE Design Suite 14.2.

Abstract: التعرف على قزحية العين هي تقنية القياس الحيوي التي تتناول تحديد الهوية على اساس قزحية الانسان. يعتبر تميز القزحية من انواع التكنولوجيا الحيوية الاكثر دقة المتاحة اليوم بالمقارنة مع انواع كثيرة من التقنيات البيومترية المستخدمة مثل : مسح بصمات الاصابع، التعر | Iris Recognition is a Biometric Technology which deals with identification based on the human iris. It is considered to be the most accurate biometric technology available today compared with many kinds of biometric technologies used, like Fingerprint scanning, Face recognition, Voice recognition and Hand geometry scanning because it has some advantages, such as uniqueness, stability and high recognition rate etc., makes iris recognition so accurate.In this proposed system, two database systems are used. The first is CASIA database system (version 1.0)(Chinese Academy of Sciences Institute of Automation). And, the second is Real database system by using real persons (each with many images) for recognition through camera Mobile Type of Galaxy Note3. An approach to get more accuracy of the offline iris recognition is composed of many steps : capturing the iris image, determining the location of the iris boundaries, normalization, preprocessed using median filter to remove noise, using wavelet transform for two types of filter, Haar and Daubechies, in order to extract the features and finally using the matching by artificial feed forward neural network with back propagation algorithm (FFBNN) for training and testing iris image.In CASIA system, the iris recognition rate for Haar filter was 84.2% and for Daubechies filter was 92.8%, while in the real system, iris recognition rate for Haar filter was 90% and for Daubechies filter was 98.7%. This means the Daubechies filter is the best in execution time and mean square error from the Haar filter. Finally, efficiency of this system is logical, because the performance measurement of False Acceptance Rates was reasonable. The results and the experiments were implemented by P4 computer and the software package MATLAB (R2011a).

Smart antenna systems can solve the problem of mobile communication system such as co - channel interference , delay spread and multipath by an advance signal processing technology called beamforming. In this work artificial neural networks (Feed Forward Neural Network (FFNN) and feedback Elman Recurrent Neural Network (ERNN) ) are used for smart antenna adaptive beamforming for one and multiple targets.Neural network is used to calculate the optimum weights of antenna array to adapt the radiation pattern of the antenna array by directing multiple narrow beams toward the desired users and nulling interference or unwanted users. FFNN and ERNN are trained by supervised backpropagation learning algorithms, FFNN was trained by using Levenberg - Marquardt (lm),Resilient Back - Propagation (Rprop), Gradient descent with momentum and adaptive learning rate (gdx), Gradient descent and adaptive learning rate (gda) and biasing regulation(br), while lm and Rprop are used to train ERNN..The simulation results show that the best performance of smart antenna adaptive beamforming for one and multiple targets is obtained when the NN (FFNN and ERNN) trained by lm algorithm as compared with other algorithms, since it consider the fastest supervised training algorithm but with more memory requirement. Where the performance of FFNN training phase based (lm) algorithm for single target for five element uniform linear array antenna is [2.746641e - 14] at epoch 27 with best validation performance and best test performance approximately equal to the best training performance. While The performance of ERNN training phase based lm algorithm for single target is [1.121938e - 14] at epoch 38 with best validation performance equal to [1.682442e - 14] and the best test performance is [3.363946e - 14].The neural network model in adaptive beamforming are compared with smart antenna adaptive beamforming based on Least Mean Square (LMS) algorithm, and gave better performance than LMS.

Abstract: The internet revolution has created the need for wireless technologies that can deliver data at high speeds in a spectrally efficient manner. However, supporting such high data rates with sufficient robustness to radio channel impairments requires careful selection of modulation techniques. The demand for high - speed mobile wireless communications is rapidly growing. OFDM technology promises to be a key technique for achieving the high data capacity and spectral efficiency requirements for wireless communication systems. Abstract In this thesis, Inverse Discrete Wavelet Transform (IDWT) is used as a modulation technique instead of Inverse Fast Fourier Transform (IFFT) with coded OFDM due to its excellent orthogonality and superior spectral containment properties of wavelet filters. Coded Orthogonal Frequency Division Multiplexing (COFDM) is the same as OFDM except that forward error correction is applied to the signal before transmission. This is to minimize errors in the transmission due to lost carriers from frequency selective fading, channel noise and other propagation effects. Convolutional code is used in this thesis as a forward error correction code. The proposed (DWT - COFDM) system is simulated under the effect of additive white Gaussian noise channel, and multi - path fading channel at different values of Doppler frequencies (22.2Hz, 41.7Hz and 444.4Hz) which are the most significant impact channel parameters on the bit error rate performance. The proposed system is also compared with DWT - OFDM, FFTCOFDM and FFT - OFDM systems. It is found that the proposed system can significantly improve the BER performance and it performs better than the other three systems. On the other hand, convolutional code and DWT is used to reduce the peak to average power ratio (PAPR) which is considered the serious problem in any wireless communication system using multi carrier modulation techniques like OFDM systems by using two of the most important non distortion techniques which are selective level mapping (SLM) and partial transmit sequence (PTS) and the results show that the proposed systems for SLM and PTS techniques can perform better than the conventional SLM and PTS. The results also show that the proposed PTS technique performs better than the proposed SLM technique.

A single phase fault with the earthing in the distribution networks causes electrical arc as well as high voltage than the two phases together which increase the danger of separation and isolation in networks. Consequently, this case can be controlled through Peterson Coil which turns off or reduces the electrical arc that makes the network safer. This work has using technique to detect the earth fault in the single - phase by distinguishing between the higher and the lower values of the currents. Also, this technique is used to detect the capacity of earthing network lines and the possibility to adapt the capacitor for inductance in order to detect the electrical arc during faults and to detect the earth leakage.Moreover, we have used many methods to control Peterson coils such as using PID Controller , Fuzzy Logic Controller, Hybrid control PID and Fuzzy System and Adaptive Neural Fuzzy Inference system, to determine the earth fault current at values equal to the current in the two sound phases. To getting best results for the fault current through conducting lab experiences by using DC Servo motor and Arduino. And the fault current is converted from the rated current, thus thousands of tons of copper cost are save. They were used to carry this high voltage. Finally, the first practical part (Simulink) was implemented through Mat lab (R2011a) and (R2013a) , On the other hand, the second practical part was in the lab, where servo motors Where used, variable and non - variable inductance , the drive to isolate the control loop from the power, PID and PWM, have also used the Arduino system to program the overdrive.

Abstract: This thesis presented durable minimization method for solving the load flow problem and contingency analysis in on - line applications. Because the electrical power networks are complicated systems, traditional (numerical) minimization methods may encounter difficulties in solving the load flow problem and contingency analysis due to properties of the problem.Thus, the fuzzy logic applications represented by the fuzzy load flow (FLF) and fuzzy contingency analysis (FCA) methods share the best selection in - stead of the traditional methods because the artificial intelligence (AI) methods do not use the characteristics of the problem to determine the next sampling point. The obtained results are very accurate with outstanding computation time, which made the FLF suitable for real time application. In addition to these features, the FLF also able to solve load flow problem of ill - conditioned power system and contingency analysis efficiently.The FLF method using Gaussian membership function requires less number of iterations and less computing time than that required in the FLF method using triangular membership function.All the obtained results show that the computation time of the Fuzzy Load Flow (FLF) is less than the Fast Decoupled Load Flow (FDLF). Using sparsity technique for the input sparse matrix data without complicating the algorithm?s programs gives reduction in overall computation time and storage requirements. The contingency ranking process by calculating the active power and voltage performance indices (PIP and PIV) are required for real power problems and voltage problems respectively for two typical test systems being the IEEE 14 - bus and 30 - bus systems. The performance of the FLF and FCA was tested on two typical test systems being the IEEE 14 - bus and 30 - bus systems in addition to the 362 - bus Iraqi National Grid.
