Due to the fact that encryption operations performed by any protocols increase the number of operations and also slow down the rate of data being sent or received over WiMAX network. Hence, Encryption may have negative effect on quality of services offered to the end users and the system capacity. The Performance enhancement over WiMAX network is needed by using optimized encryption algorithm, which reduces computations overheads. In this exertion, a proposed optimized encryption algorithm, which adopts AES algorithm as the encryption algorithm, is presented. In previous work[1], a customized version of the “AES” block cipher was introduced to suit proprietary data encryption applications. In this paper, a higher security level for optimized AES is proposed by adding a dynamic permutation unit of input data in every round which allowing number of round reduction possibility, improves network performance and increases diffusion propriety for each round.

The paper is concerned with generating of narrow-band dual polarized Multi Input Multi Output (MIMO) over land Mobile Satellite (LMS) fading channels. In the absence of accurate experimental results of MIMO-LMS channels, a statistical model for the characterization of MIMO-LMS is proposed based on available experimental results for Single Input Singleoutput (SISO) LMS and MIMO wireless channels as well as on their extrapolation to the MIMO-LMS case of interest. In this paper a step-bystep methodology for transforming SISO model (Loo model) to MIMO model with detailed description and block diagrams for the simulation and time series signal generation for MIMO-LMS, with the desired power, probability distribution, covariance relations and spectrum. Moreover, based on the proposed channel model, the channel capacity statistics as well as the error performance of a SIMO-LMS diversity system, assuming both maximal ratio combining (MRC) and selection combining (SC), and MIMO-LMS using Space-Time Block Code are evaluated through simulations. Useful numerical results on the capacity are also provided taking into account several operational system parameters. The simulation model and results are useful for LMS-MIMO physical layer researches and system designer, who need an easy to implement and realizable model, representative of typical MIMO-LMS communication systems.

Frequency Hopping Spread Spectrum (FHSS) is a technique that wireless devices communicate such that the transmission frequencies are alternated in a pre-determined ordered hopping pattern. In tradition, the hopping sequence is controlled by using a pseudo-random code sequence (PN code) known only to both transmitter and receiver. In this paper, the carrier frequency of a frequency shift keying FSK system is interfered by the surrounding environment. Thus, FHSS will be used instead to switch between multiple carriers within the available bandwidth to minimize the interference. Such a system requires that the generated PN code ensures that all carrier frequencies within the hopping pattern should be semiequallyused during transmission. Several simulation scenarios were carried out to compare between a single long PN code and an accumulated short one. Finally, the developed FH system is implemented using an AD9910 Direct Digital Synthesizer (DDS) and an ALTERA Cyclone-III FPGA chip. Results proved that, according to the system requirements, an accumulated short PN code offers noticeable residual correlations and provides a higher level of autocorrelation compared to a single long PN code. Results, also, verified that the developed FH system provides lower Bit Error Rate (BER) than the FSK one.

This paper aims to explain the design and planning of a passive optical networks (PON) which can build a fictitious environment allowing to study fiber to the home (FTTH) networks in depth and decide the optimal option for thisenvironment. We design a network architecture based on FTTH systems with different bit rates (1.25 GB/s, 2 GB/s, 2.5Gb/s,5Gb/s and 10 GB/s). This architecture is targeted to deliver a very high speed data using optical communication between the edge nodes connecting the end users. This transmission allows the simultaneous delivery of triple play service (data, voice and video). In our design various data rates are studied. It has been observed that the proposed system is one of the most suitable methods concerning data rate. It is demonstrated that as we increase the datarate, the number of accommodated user's decreases due to high bit error rate. Also by increasing the distance of transmission, the system will be undesirable due to increasing the bit error rate.

Spread spectrum signals are widely used for secure communications, as well as for multiple access interference (MAI). They have many interesting properties, including low probability of interception. Indeed, direct sequence spread spectrum systems (DSSSS) use a periodical pseudo-random sequence to modulate the baseband signal before transmission. Interception of DSSS signals is a difficult task due to the hiding of the PN sequence, especially if the accompanied noise is non-Gaussian and the channel is time varying. In this paper, a receiver is proposed to intercept asynchronous direct sequence code division multiple access (DS-CDMA) signals received from different users and estimate the PN sequences of each one of them. The signals are assumed to be transmitted over time varying flat fading channel and contaminated with Class-A impulsive noise. The proposed interception receiver is based on Independent Component Analysis (ICA). The proposed receiver is tested for different types of PN sequences including m sequence, Gold sequence, and Walsh codes. The results show that the interception receiver is not sensitive to the time variation of the channel and to the type of PN sequence. Moreover it is found that the receiver performs well for low signal to noise ratio and for any type of PN codes.

Cryptographic hash functions are an important tool in cryptography for applications such as digital signature of messages, message authentication, and key derivation. This paper presents a new cryptographic keyed hash function design, named Concrete Hash function Algorithm, CHA-128, which has some difference from the popular hash function designs and used for ensuring integrity of messages to a higher degree to suit the fast growing network applications. The function structure is designed permit a wide variety of implementation tradeoffs. Also CHA is proposed as very smooth 128 bit hash function algorithm, which is designed according to permit a wide variety of computing implementation tradeoffs. By very smooth, it means that the smoothness bound is multiple fixed sequential functions. A valuable comparison between the softwareperformance of CHA-128 design and some popular hash function algorithms designs is performed.

During the last decade, the need for highly precise positioning services, for both military and civilian applications, has grown significantly. Unfortunately, in some environments such as dense urban or indoor areas, the Global Navigation Satellite System (GNSS) suffers from poor precision and lack of satellite visibility. Therefore, another positioningsystem is required to replace or augment GNSS in those environments. The use of Signals of OPportunity (SoOP) is one example of these complementary systems. Previous work explored different positioning techniques using SoOP from a wide variety of sources including; cellular phone signals, analog and digital TV, as well as audio signals. This paperfocuses on the use of WiMAX signals, which is rapidly finding its way in the military environment, as a SoOP for position estimation. The positioning technique in this work is based on the Received Signal Strength (RSS) technique. Moreover, Kalman filter will be used to improve the position estimation results of that system.

The demand for efficient, real time video cryptography systems has become more prominent in our life, especially for military and sensitive-civilian applications. The proposed system design was constrained in both area and speed in order to fulfill the requirements for real time video signals with limited hardware resources. Using Field Programmable Gate Array (FPGA) for the system implementation is suitable for both video and cryptography processes due to video data rate, flexibility to design modifications, and cryptography algorithm agility. The design strategy was based on making use of all available pre-designed, pre-verified cores for low cost Xilinx Spartan III XC3S1000-ft256 FPGA chip. In this system, only active video data are encrypted with (Rijndael) Advanced Encryption Standard (AES) crypto algorithm and a self-synchronized cipher key mechanism based on the embedded video Timing Reference Signals (TRS) was designed to overcome the security leakage in Electronic Codebook (ECB) mode and to reduce the possibilities of cryptanalytic attacks which are used to recover the encryption key like brute force attacks. The design is tested first using an internally generated video pattern, then using external composite video camera source. The design implementation results were significant for speed and area, it reached 59.044 Mbytes/sec. data throughput that fulfills the minimum requirements of colorful, 30 FPS video data rate of 27 Mbytes/sec., and the design occupies 4,007 slices (52% of chip size).

The multi-agent system concepts appeared recently and it is extremely distributed in all research areas to solve problems by many agents cooperation. In some applications, quick, accurate, and complete data is highly required for supporting decision making in order to reduce the decision cycle and to minimize the loss. Multi-agent data fusion has been used for such applications where the process of integration of multiple data and knowledge is turned into a consistent, accurate, and useful representation. The benefit of using multi-agent data fusion is that it can use for large structural, collect as much data as possible using different kinds of sensors with low cost. This paper presents a multiagent cooperation system using a real time processor based on FPGA which is used as parallel processing to speed up the processing, measuring the time and the amount of data being processed. This makes real-time or near-real-time damage detection possible.The proposed multi-agent data fusion system is evaluated by a bridge aluminum structure monitoring experiment in which strain distribution are monitored by a set of sensors.

W. Sabry

Egyptian Armed Forces.
Electrical power systems are widely distributed systems, consisting of a large number of interconnected synchronous generators through transmission lines, mounting real and reactive power. Moreover, with deregulation and growth of the power industry, power systems elements are forced to operate very near to their maximum capacity and hence, the system becomes vulnerable. Therefore, controlled operation of power systems is very critical and of utmost importance in order to achieve stable power system. Naturally, this paves ways for implementing fast, efficient and reliable control algorithms. Robustness and efficiency of power system controllers can be improved by using complimentary models of intelligent systems. Difficulties encountered in designing controls for nonlinear, dynamic and uncertain systems can be easily tackled by using intrinsic observability property of various intelligent systems. Intelligent controllers have been successfully applied to enhance operation and control of power system. This paper presents an implementation of four different Fuzzy Logic based intelligent controllers through the excitation system of the synchronous generator:Conventional Fuzzy Logic Controller (CFLC), Adaptive Fuzzy Logic Controller (AFLC), Adaptive Neuro-Fuzzy Logic Controller (ANFLC) and Takagi-Sugeno Fuzzy Logic Controller (TSFLC). A comparison between the four proposed intelligentcontrollers are presented.

PI and PID Power system Controller: Eigenspectrum-Based Design and Sensitivities

Academy For Science, Technology & Maritime Transport.
A proposed design procedure for PI and PID type controllers is presented in the present paper utilizing eigenspectrum assignment as a design tool. As it is well known that the right eigenvector gives the mode shape, i.e. the relative activity of the state variables when a particular mode is excited, while the left eigenvector identifies the weights for the contribution of the activity to the mode. In the analysis and operation of power systems, one needs to assess the influence of some parameter variation that may be a source of oscillations and deteriorate the frequency and tie-line power regulation. This includes what might be considered "natural" modes of oscillations that are due to the inherent system characteristics as well as "forced" modes of oscillations that are driven by a particular system. A comprehensive treatment and evaluation for the sensitivities of eigenvalues and eigenvectors are presented.

This paper deals with the design of Fuzzy Proportional Integral and Derivative FPID controller self tuned by Relative Rate Observer RRO method. The developed approach is applied to the Load-Frequency Control LFC of the Egyptian power system EPS as a single area with multi unit power system. The studied power system comprises three power plants; non-reheat, reheat and hydro generation plants. The proposed FPID controller is designed on an average point of four loading conditions of the EPS during summer and winter of 2008. The effectiveness of the proposed FPID self tuned by RRO(FPID-RRO) has been demonstrated by introducing the system nonlinearities using MATLAB-SIMULINK simulation program. Moreover, a comparison of the FPID with FPID-RRO controllers under different disturbances and parameter variations are presented to validate the FPID-RRO controller. The simulation results reflect and prove fast settling time and accurate tracking for the LFC of the Egyptian Power System.

This paper proposes and provides the design steps of three robust output feedback controllers to control the frequency of Wind-Diesel-Hydro hybrid system. The first presents a centralized robust based H¥ (CRH¥) controller. The role of H¥ is to minimize the disturbance effect on the system output. The effect of the LMI tuning variables of RH¥ controller on the system dynamic performance is presented and discussed. The controllers are solved using the Linear Matrix Inequalities (LMI) technique and characterized by a similar size as the plant that may be of higher order and thus creates difficulty in implementation in large systems. The second presents decentralized robust based H∞ for each unit (DRH¥). The third is robust PID controllers which are ideally practical for industry and more appealing from an implementation point of view since its size is lower. The optimum parameters of the robust PID controllers are found through the optimization by a novel combination of RH¥ control theories through the Genetic Algorithm (GA) technique. More specifically, the third robust PID controllers are proposed to achieve the same robust performance as decentralized(DRH¥) controllers, respectively. All controllers are used as load frequency controllers to control the Wind-Diesel-Hydro hybrid system . Comparisons of the performance of the three robust output feedback controllers under diverse tests in different disturbances and variation in the plant parameters are carried out.

A satellite moving in relation to a GPS receiver generates a shift in the carrier frequency and the C/A code signal reception. This deviation is know as the Doppler effect and it varies in time depending on the relative acceleration of the GPS satellite/receiver and it can hinder or even preclude data reception. This paper presents an approach to mitigate thisproblem, with the insertion of adaptive filters in the tracking loops in order to use conventional GPS receivers in systemssubjected to low and high accelerations. The results are compared with those obtained from the use of non-adaptive filters.

Interference is one of the major concerns in using the global positioning system (GPS) for civilian and military applications. In this paper, a closed form analytical expressions for the continuous wave interference (CWI), and matched spectrum interference (MSI) power at correlator output are derived. The post-correlation carrier to noise ratio (C/No)for the GPS L1 coarse acquisition (C/A) signal is analytically derived in the presence of CWI, and MSI. The effect of the GPS correlator coherent integration time is also investigated under the impact of these interferences. The derived analytical formulas are verified by extensive the computer based simulation result.

In this paper, the orthogonal frequency division multiplexing (OFDM)- based Wi-Fi IEEE802.11a signal parameters (bandwidth, subcarrier spacing, and the number of subcarriers) are experimentally estimated over a band of signal to noise ratio (SNR) values. The estimation of the considered OFDM system parameters is blindly done with the aid of OFDM power spectrum properties. The estimation is evaluated under the assumption of additive white Gaussian noise (AWGN) and frequency selective multipath fading channels. The proposed estimation technique based on power spectrum processing technique which takes full advantage of the cryptic period of the OFDM signal. It was shown that the proposed method is applicable for medium SNR and it requires low computational complexity.

Linear frequency modulated pulse compression (LFM-PC) radar is one of the widely used modern radar systems. It has high immunity against conventional noise jamming due to its high processing gain. To sufficiently affect such radar, smart jamming techniques should be applied. In the last decade, different smart jamming techniques have been proposed. However, literature lacks to the analysis and evaluation of the effect of such techniques on modern radar systems. In this paper, the effect of one of the recently proposed jamming techniques, called chopping jamming, is analyzed andevaluated against LFM-PC radar depending on a typical LFM-PC verified radar model. The worthy of the application of chopping jamming on LFM-PC radar regarding to the probability of false alarm as well as radar detection is discussed and presented.

The use of wireless sensor networks to protect sensitive facilities or international borders has recently attracted more and more attention [1-3]. It has become a highpriority issue in many countries. In addition to the physical fences built for stopping illegal intruders from crossing the border, smart fencing has been proposed to extend intrusion detection capabilities. Event detection is a central component in numerous wireless sensor network (WSN) applications [4, 5]. In spite of this, the area of event description has not received enough attention. The majority of current event descriptionapproaches rely on using precise values to specify event thresholds [6, 7]. However this crisp values cannot adequately handle the imprecise sensor readings. Therefore, In this paper, Event-detection algorithm based on two layers fuzzy Logicsystem (FLS) is used, which conveys the idea of using fuzzy values instead of crisp ones which significantly improves the accuracy of event detection. Each sensor node has an acoustic signal sensor and one-axis acceleration sensor to improve the precision of the detection system, as well as reducing false alarm rate specially in a noisy environment.

Laser warning receiver is the basic materiel for implementing laser countermeasure. It is very significant with regard to effectively self-protect and destroy the enemy in battlefield. Its function is to detect incidence laser signal, to measure laser parameters. However, Most of the existing system has a complex hardware especially if it gives the direction of the incident laser. In addition, it may face the problem of background sun light suppression. In this paper a simple intelligent algorithm for laser angle detection is proposed using fuzzy logic data fusion to detect laser incidence angle for early warning. The proposed system is simulated and tested using MATLAB software using four laser sensors to detect the incident laser angle from 0 to 360 and an additional sensor to distinguish the incidence laser from background sun light.

Inertial Navigation Systems (INS’) are used as a primary mean of navigation in mostly all of the unmanned and autonomous systems. INS accuracy is categorized as grades in which the navigation grade is the most accurate and commercial grade is the least. The requirement of any used INS is to provide high accuracy information on the position, velocity, and attitude over a certain period of time. The problem of using low grade INS is that their accuracy degrades rapidly with time. To provide accurate estimation of navigation information, modeling of the sensors' noise components is required. The sensors’ noise components are categorized in deterministic and stochastic parts. Deterministic noise such as bias and scale factor is easily removed in a process of laboratory calibration. Stochastic noise is the hardest part and needs special processes to be modeled and removed. Allan Variance (AV) technique is a time domain method which can be used to characterize various types of stochastic noise terms appear in inertial sensor data by performing certainoperations on an amount of data. In this paper, the relationship between different parameters which affect the operation of low cost Micro Electro Mechanical System (MEMS) inertial sensors such as sensor bandwidth and sampling rate is explored using Allan variance technique. Test results show that by carefully choosing internal inertial sensor settings, thesensor stochastic noise can be accurately modeled and hence, navigation processing is highly improved.

Switching frequency variation over the entire operating speed range of an induction motor (IM) drive is the major problem associated with conventional two-level threephase hysteresis controller as well as the space phasor based pulse width modulation (PWM) hysteresis controller. This paper presents a new variable band hysteresis current controller for controlling the switching frequency variation in the two-level PWM inverter fed IM drives for various operating speeds. A novel concept of online variation of the band based on both the instantaneous load current and current change for eachsampling period is presented to determine the hysteresis band. A performance comparison of the proposed with conventional hysteresis current controller for IMdrive is provided in simulation. The proposed drive system is also implemented in real-time using DSP board DS1104 for a laboratory 1.5 hp motor. Comparative simulation andreal-time results verify the feasibility of the proposed scheme and demonstrate that the proposed method has obtained constant switching frequency and improved the performance of the drive system.

This paper presents the study of a three phase PWM inverter-fed induction motor drive with single phase utility input, with and without a power factor correction circuit (PFC). The PFC circuit is controlled with the proposed predictive current control. The effects of the PFC circuit on the magnitude of the input current, harmonic contents and input power factor of the A.C drive system are studied. The Fast Fourier Transform (FFT) is used to get the frequency spectrum of the current waveforms. A comparative study of simulation and experimental results for the A.C. drive system, with and without PFCcircuit, is carried out. The experimental implementation of PFC control of the boost converter controlled three-phase IM drive system, with FOC principles in real time, using DSP controller board DS1104 is achieved using the proposed predictive control. The proposed PFC control method used to achieve a low input line current harmonics, for obtaining a good power quality with a fast dynamic response for output voltage and line current.

This paper presents modeling, analysis and control of a grid connected doubly fed induction generator (DFIG) wind turbine, during steady-state and transient operations. A mathematical model for different parts of the wind energy conversion system using DFIG has been examined using MATLAB/SIMULINK. A control structure using standard proportional integral (PI) controller and a voltage-oriented control strategy based on a rotating reference frame has been used. The machine model considers operating conditions below and above synchronous speed. The Maximum Power Point Tracking (MPPT) method has been presented also to improve efficiency and energy extraction in wind turbine systems. Characteristic power curve method has been used as one of the popular MPPT methods. In this paper, simulation results of the DFIG model have been presented. Then, DFIG model has been connected to the grid model and examined using PI controller under different conditions. The Internal Model Control (IMC) method has been used for tuning the PI controller. The proposed PI controller shows stable operation at different conditions.

Antenna arrays have been recognized by most fourth generation CDMA systems proposals as a way to enhance the capacity and system coverage by effectively combating multipath fading and mitigating co-channel interference. The multiple access interference (MAI) problems can be overcome by power control by the process so that the averagereceived power at base station is same for each user. The paper introduces a new approach to outage probability analysis of prediction maximal ratio combining (MRC) diversity reception in Rayleigh fading channels. The analysis joins several of the most important factors affecting the performance of CDMA systems; including path loss, large-scale fading (shadowing), small-scale fading (Rayleigh fading), and co-channel interference (CCI) as well as for correcting mechanisms such as power control error (compensates for path loss and shadowing), spatial diversity (mitigates against Rayleigh fading), and voice activity gating (reduces CCI). We show that by controlling the power level of a user at the output of the diversity combiner (MRC) and imposing the condition that a user does not transmit when in a deep fade; the average inter-cell interference level of the system is significantly reduced. As a result of this reduction, we demonstrate analytically that the outage capacity of the system is improved more than linearly with increasing number of antenna elements.

This paper aims to explain the design and planning of a passive optical networks (PON) which can build a fictitious environment allowing to study fiber to the home (FTTH) networks in depth and decide the optimal option for this environment. We design a network architecture based on FTTH systems with different bit rates (1.25 GB/s, 2 GB/s, 2.5Gb/s,5Gb/s and 10 GB/s). This architecture is targeted to deliver avery high speed data using optical communication between the edge nodes connecting the end users. This transmission allows the simultaneous delivery of triple play service (data, voice and video). In our design various data rates are studied. It has been observed that the proposed system is one of the most suitable methods concerning data rate. It is demonstrated that as we increase the data rate, the number of accommodated user''s decreases due to high bit error rate. Also by increasing the distance oftransmission, the system will be undesirable due to increasing the bit error rate.

Octagonal shape monopole antenna with dual band notched features which is used for ultra wide band applications is presented. The monopole antenna has good impedance matching from 3.4 GHz to 12 GHz. The dual bands notched are achieved by using Ushaped parasitic strip and meandered slot etched in the radiating patch. The first band notched is achieved using meandered slot to reduce the interference with WIMAX from 3.3 GHz to 3.9GHz.The second band notched is achieved using U-shaped parasiticstrip which is placed above the ground plane to eliminate the interference with WLAN from 5.2GHz to 5.9GHz . The proposed antenna has VSWR < 2 except the notched bands. The simulated results confirm that the proposed antenna is suitable for UWB applications.

Number of risks occurs for the development of successful software project. Sometimes it disturbs the schedule of whole project that result in the increase of cost. Therefore, the avoidance and mitigation strategies are used to overcome the effect of risk in the project. If software team use proactive approach then avoidance is the optimize solution but not all the risk can be avoided then it have to mitigate, and when risk become a reality, contingency plan has developed. The intention of this paper is to highlight number of risks, their arising issue and how to resolve them.

In recent years software has become a key element of safety critical systems. The use of Safety Critical Software Systems (SCSSs) has been increased in many critical systems such as Nuclear Power Plants (NPPs), radiotherapy, aircrafts, and many medical devices. These systems rely on the use of safety critical software in controlling and monitoring critical devices. SCSSs are developed in accordance with a set of guidelines and standards produced by the industry, or imposed by a regulator. Despite of the vital role of SCSSs in saving human life, the environment, and properties, there is no generic methodology for developing such systems based on standards and guidelines. This methodology sets an integrated model that concerned about the safety of critical software systems as a component of the critical systems. It consists of the needed processes required for developing SCSSs free of faults. This methodology ensures that SCSSsare developed using processes based on appropriate standards and guidelines and can be certified accordingly. The objective of this methodology is to produce certified critical software systems that conform to standards and guidelines. The methodology consists of three phases (safety planning and requirements phase, safety analysis phase, and design, implementation, and operation phase). This paper is going to focus on design and implementation phase. The insulinpump system is applied as a case study on the design and implementation phase.

The demand for Multi-Protocol Label Switching (MPLS) is increasing day by day in most internet service provider networks. MPLS provides efficient forwarding, routing and switching of traffic flow through the network. MPLS technology has proven itself in providing the required Quality of service (QoS) needed by multimedia and real time application traffic, but it’s almost impossible to convert the existing entire huge IPv4 networks to MPLS technology. This paper simulates hybrid IPv4/MPLS networks to overcome multimedia applications QoS problems by obtaining a performance close to pure MPLS network performance. Three different scenarios are investigated using OPNET simulator. Those scenarios are pure IP network, pure MPLS network, and hybrid IP/MPLS network. The simulation results point up the pros and cons of eachscenario in terms of end-to-end delay, delay variation, packet loss ratio, packet delivery ratio, and voice MOS value. In short, pure MPLS network provides the best performance for multimedia traffic but close results can be achieved using hybrid IP/MPLS network.

The recent growing of the Semantic Web requires the need to cope with highly semantic heterogeneities among available ontologies . The Semantic Web envisions a metadata-rich Web where presently human-readable content will have machine-understandable semantics. Ontology matching techniques aim to tackle heterogeneity by establishing correspondences between ontologies’ elements. An intricate obstacle faces the ontology matching problem is its scalability against large number and large-scale ontologies . This paper is comparative analysis among the different matching algorithms that tackle heterogeneity and recommend the algorithms that would fit for highly scalable systems.

This paper presents an enhanced particle swarm optimization (PSO) algorithm, which applied to reactive power compensation (RPC) problem. It integrates the merits of both GAs and PSO and it has two characteristic features. Firstly, the algorithm is initialized by a set of random particles which traveling through the search space, during this travel; an evolution of these particles is performed by a PSO coupled with GA to get approximate nondominated solutions. Secondly, to improve the solution quality, dynamic version of pattern search technique is implemented as neighborhood searchengine where it intends to explore the less-crowded area in the current archive to possibly obtain more nondominated solutions. Also In order to study the algorithm performance, the effect of change of the most significant parameters of the proposed approach was studied. The proposed approach is carried out on the standard IEEE 30- bus 6-generator test system. The results demonstrate the capabilities of the proposed approach to generate true and well-distributed Pareto optimal nondominated solutions of the multiobjective RPC. Also the results declare that it is quite difficult to find fixedvalues for these significant parameters, thus we recommend to develop dynamic version of the proposed approach using any monitoring algorithm.

The requirements for managing distribution systems continue to present new challenges. Electricity is one of the most vital infrastructure inputs for economic development of a country. The demand for electricity in Egypt is enormous and is growing steadily. This growth has been slower than country’s economic growth. To balance this demand and supply of electricity, it is the time for electric utilities to go for energy efficient electrical equipment for huge savings as this would be utilized for future needs .Therefore, great effort has been directed to increasing the efficiency of distribution transformers and consequently reducing the losses and, hence, the operational costs. International standards, published by means of norms, define the power efficiency of transformers, taking into account the no-load losses, the load losses and capitalization equations. An increase in distributor efficiency is obtained through prior knowledge of loads per unitloading and power factor adequateness. The objective at Middle Egypt Electricity Distribution Company (MEEDC) is to offer the best service to its customers through knowledge of their system and also through the acquisition of efficient equipment. The measurements of about forty different rating transformers are analyzed and their efficiency are calculated according to energy efficiency methodology These values are compared with the ideal transformers efficient tables at the same rating. Some steps are applied to energy efficiency improvement and presented.

The Electric distribution Companies (EDCs) are responsible for keep power quality indices (PQIs) under the standard limits. Magnitude of the supply voltage, harmonic distortion and unbalance are taken into consideration among the PQIs. These indices are considered not to be exceeded on low voltage and medium voltage distribution networks. Voltage variations are small deviations from the nominal or desired value. Voltage variations are mainly due to load pattern, changes of load or nonlinear load. The voltage unbalance causes increased unbalance harmonic currents, mainly non-zero sequence triple harmonic distortion. Harmonic distortion is caused by nonlinear devices in the power system; sources of distortion are different at different voltage levels. At low voltage level all kinds of non-linear loads are connected, which globally is the main source of distortion at all voltage levels. The harmonic indices are total harmonicdistortion, spectrum harmonic and harmonic loss factor. The voltage distortion levels depend on both the circuit impedances and the overall harmonic current distortion. Modern industrial facilities are characterized by the widespread application of nonlinear loads. These loads can make up a significant portion of the total loads and inject harmonic currents into the power system, causing harmonic distortion in the voltage waveforms . Commercial loads arecharacterized by a large number of small harmonic-producing loads. The unbalanced and nonsinusoidal working conditions have a negative impact on both individual components of the electrical system and the whole system. End users expecting an improved level of service may actually experience more problems. Equipment failure, mal-functioning, pre-aging, andtelephone interference can locally be a server problem, at all voltage levels. Middle Egypt Electricity Distribution Company (MEEDC) is using the PQIs to improve their systems. One productive use of the indices is to compute the POIs power delivery system at distributors as well as the PQIs for several of the industrial networks. This paper reflects and focuses on the PQIs survey in MEEDC networks. The results of the PQIs survey are presented.

This paper reflects and focuses on Energy Efficiency (EE) for commercial institutions and public utilities. The EE of a building is the extent to which the energy consumption per square meter of floor area of the building (kWh/m2/annum) measures up to established energy consumption benchmarks for that particular type of building under defined climatic conditions. Building energy consumptions benchmarks are representive value for common building types against which a building actual performance can be compared. Benchmarks are applied mainly to heating, cooling, air conditioning, ventilation, lighting, fans, pumps and controls, office or other equipment and electricity consumption for external lighting.In Egypt, there are important opportunities to improve EE in government facilities, operations, and public infrastructure and services. Benefits include lower government energy bills, reduced greenhouse gas emissions, less demand on electric utility systems, and reduced fuel. In the paper five case studies are carried out. The steps are preparing the auditing, monitoring the electrical parameters, analyzing the measurement result and inspection data and option solution to provideEE improvement.

A number of indicators to measure Energy efficiency (EE) performance was developed by different organizations. The World Energy Council (WEC) has developed a number of indicators for measuring EE performance. The WEC residential EE indicators are; (i) KWh/household, (ii) KWh/Capita, (iii) Solar water heaters/Capita and (iv) emissions in CO2 (Ton)/household. The EE indicators are developed to promote and support development, introduction and implementation of EE policies. Furthermore, the EE indicators are measured (i) to monitor changes in EE and (ii) to allow comparisons of different EE situations. Improving EE, for electric power use in specific, will result in: 1- Better utilization of the available generation capacity to supply more customers, 2- Slow down of the power demand growth, and 3- Reduction of the investment needed for expansion of the electricity sector. In Egypt, there are nine Electricity Distribution Companies (EDCs). Each consists of a number of geographical sectors. Each sector is further divided into districts. The district network consists of distributors, distribution transformers, and LV & M V Lines. Egypt era (Egyptian electric utility and consumer protection regulator agency) has collected and classified database of residential sectors for the nine companies.There are different log sheets with information about districts and sectors. The main log sheet data for each sector acquired are:- Monthly KWh & No. of households for each district- Monthly tariff category KWh & No. of households for each sectorThe EE indicators are calculated accordingly using a residential sector hierarchy based on household data, which relates between reliability of Composite Energy Indices (CEI), and the level of sector disaggregation. The residential sector covers all types of residential units. These sectors are further classified based upon nature of rural and urban area. This paper presents a set of EE indicators developed during five years period. The data set is used to analyze the EE indicators of Electricity consumption in different levels in residential sector. The paper compares the EE indicators among the different geographical regions. It discusses the criteria for the peer group selection. The paper presents the comparison on district level, and company level. Furthermore, the paper looks at the possibility of comparing the over all country EE performance to other countries.

The quality of tomographic images formed from diffracting waves deteriorates due to the limitations in capturing evanescent waves. The waves carry detailed information about the body being imaged. Metamaterials are being recently used to amplify and focus evanescent waves. Here, the physical characteristics of a hyperlens made out of a silver metamaterial slab are studied. A description of the equations for wave propagation inside the metamaterial is shown.The dependence of the cutoff frequency of a hyperlens on the thickness of the slab is discussed. Suitable physical dimensions of a hyperlens are proposed for cross sectional imaging of objects imitating the characteristics of human body. Simulations are done to test the validity of the proposed solution.

This paper presents a compact size dual-band BPF embedded in a low temperature cofired ceramics (LTCC) designed to produce two passbands for WiMAX applications. The dual-band BPF center frequencies are 3.5 GHz and 5.8 GHz. A design methodology as well as design guidelines are proposed based on stepped-impedance coupled resonators to produce dual-band response. This dual-band BPF is simulated, optimized and verified. The proposed filter provides better size reduction and at the same time performs superior enhancement in insertion losses and keeps adequate passbands compared to other published dual-band packaged filters.

PhD, Air Force R&D.
This paper is presenting a detailed comparison study for two different guidance strategies. The first strategy is concerning the difference angle between the desired heading or elevation referred to the next waypoint and the actual heading or elevation of the unmanned helicopter model. The second strategy is concerning the relative distance between the actualand the desired trajectories. In other words the first method is tracking the waypoints while the second one is tracking the trajectory. In this work a comparison study was conducted through the mentioned strategies simulation to show the significant differences in the output performance. Some performance indexes were presented to evaluate the system performance errors and the control effort needed for both strategies using the same desired trajectory and the same waypoints.

The huge developments in embedded systems in addition to its availability for civilian applications in low cost, size and weight attract the researchers in the field of navigation, guidance and control all over the world towards the embedded flight control and autopilots. One of the flight control subsystems is the control fin drive that is responsible of the flying vehicle fins motion control. This paper is devoted to the design and implementation of embedded control fin drive that can be utilized with different guided vehicles such as guided missiles, guided munitions, and unmanned aerial vehicles (UAVs). The design includes calibration of available actuators and feedback sensors in addition to the design of conditioning networks, interfacing and classical controller to stabilize this subsystem and achieve the performance requirements. Also, the design justified against disturbance and measurement noises. The tests conducted with the designed hardware and the available actuator via the Hardware in the Loop (HIL) simulation show good performance concerning tracking, disturbance rejection and measurement noise. However, the controller necessitates extra tuning to become less sensitive to noises, which is the objective for future work.

Unmanned aerial vehicles (UAVs) have become a hot research topic in the worldwide due to their great potential in numerous military and civil implementations. This motivated everincreasing attraction of designing UAV flight control systems to achieve robust stability and acceptable performance across specified flight envelopes. Therefore, this paper is devoted to design an adequate flight control system for stabilizing a fixed wing (Aerosonde) UAV. To achieve this objective, successive activities are considered including the derivation of aircraft nonlinear equations of motion and tailoring them for use on the underlying aircraft. The dynamics of both sensors and actuators are integrated to the nonlinear model in a modular Simulink model. Trimming the nonlinear model for steady-state flight and extracting the linearized models for the UAV are then considered. Two different design techniques are used for designing the UAV flightcontroller; the classical PID and the fuzzy controllers. A comparative synthesis between these controllers is performed for specific altitude and speed commands. Simulation results showed acceptable responses except that the fuzzy approach yields better time responses and disturbance rejection than the classical one.

Contamination on outdoor insulators enhances the chances of flashover and can lead to transmission line outages and reduced system reliability. In practice, various contaminant types, usually classified as soluble and insoluble, settle on outdoor insulators and increase the possibility of flashover. The paper assesses the flashover performance of such insulators in Egypt; in view of the nature and composition of contaminants accumulated on their surfaces. To quantify these contaminants, numerous samples are gathered from different regions of the country and subjected to a comprehensive chemical analysis at the scale analysis laboratory of the Egyptian Electricity Transmission Company. Measurements of equivalent salt deposition density (ESDD) surface conductivity (SC), maximum leakage current (MLC) and flashover voltage (FOV) were conducted and correlated to the contamination constituents. The study utilized IEC standard cap-pin suspension insulators which were hanged in regions of different pollution levels and nature. Regression models for predicting the flashover voltage as related to ESDD and MLC as related to surface conductivity were developed.The models are validated through statistical analysis as well as comparison with measured data. The results from this work are useful for utilities to take adequate measures to improve the efficiency of their transmission systems through scheduling of their insulator maintenance strategy and selecting the appropriate insulator design for different system voltages and regions.

This paper introduces the mathematical modeling of an advanced member of flexible ac transmission systems (FACTS) controller which is a unified power flow controller (UPFC). This model submitted the implementation of the device in conventional Newton–Raphson (NR) power flow algorithm; it is derived from two-voltage source represented and analyzed in detail. The model takes operational losses of UPFC into account so it represents a more robust and feasible alternative than other methods. Based on the proposed model a program in Matlab language has been written to extend conventional NR algorithm. A computer simulation study performed on IEEE 14-bus test system and IEEE 30-bus test system are presented to test the approach by locating the UPFC anywhere in a power system. The effect of UPFC allocation on power system operation has been investigated in detail and the power losses minimization of the power system with UPFC has been achieved using the proposed method by adjusting the location of UPFC with a proper adjustment of UPFC parameters.

This paper focuses on the design and implementation of an automatic control system based on microcontroller that enhances the load power factor (PF) in real time. The system is designed to detect the load power factor and improve it automatically. The system is composed of several elements; the main is microcontroller which compares between the measured load power factor that is received from the energy metering integrated circuit (ADE7763) and a pre-stored value “PF = 0.95”. Based on the calculated difference in power factor, the microcontroller drives the power switches(relays circuit) through an interface circuits to choose the appropriate capacitor bank that is required to improve the power factor. Furthermore, the system is able to send the system power factor data in real time to clients either by a Short Message Service (SMS) through an integrated GSM module or by the World Wide Web (internet) through an integrated Ethernet module.

In recent years, much has been studied on the colonoscope because it is a very important tool for diagnosing colon cancer, which is the second leading cause of cancer in the developed countries. Colonoscopy is one of the most technically demanding endoscopic examinations in the modern health service. This is a procedure often painful for the patient and complex for the surgeon. The conventional process involves manual insertion and manoeuvring of the colonoscope by the surgeon, which may lead to some problems like intestine perforation that might occur when the colon wall is punctured due to the colonscope being forcibly pushed by the surgeon to ease its penetration through difficult corners. Therefore, it is important to redesign conventional wired colonoscope devices to facilitate their safe insertion and navigation into the bowel. This project is concerned with the development of electromagnetic actuators, which can produce uniformly distributed magnetic field capable of generating high magnetic thrust forces. In this activity, different actuators have been investigated for the purpose of colonoscope actuation through difficult corners of the colon, which would improve its penetration problems and reduce the intestine perforation problems. ANSYS, finite element analysis, FEA, software has been utilised to design the electromagnetic circuits of the actuators which incorporate magnetic and non-magnetic materials that could generate the magnetic force required for the navigation and actuation of the colonoscope. The mechanical design of these actuators was then carried out using Solidworks CAD software.

We propose and demonstrate experimentally the possibility of reproducing the attenuation coefficients, Young’s Modulus, the acoustic reflection coefficients, and the thermal conductivity of a real biological tissue which using 2% Agar based phantom (2g Agar for 100ml degassed water).The design of 2% Agar based phantom fabrication is discussed. The attenuation coefficient is measured using measurements of the acoustic properties and Young’s modulus is measured using the mechanical compression test by applying the relation between the Nominal Stress and the Nominal Strain. Phantom is a material that simulates some properties of body tissues. It is important for helping the development of Hand-Eye coordinate necessary for ultrasound guided intervention and also allowing the performance of the simulated interventions without having to do it as the first time in the patient. Acoustic properties were measured for the frequency of 4.8M Hz at a range of ambient temperatures (10 – 35 °C). The acoustic velocity of the TMMs remained relatively constant with increasing frequency.

Biomedical engineering department, Military Technical College, Cairo Egypt.
In this study, Surface electromyography (sEMG) signal is used to evaluate the biceps brachii muscle by estimating the muscle fatigue during isometric contraction. Sample of eight males performed isometric action using the biceps brachii muscle with different levels of force and loads. The surface electromyography (sEMG) signal was recorded by the MP 100 EMG system (BIOPAC Systems, California) for 120 seconds intervals without rest in order to achieve the fatigue, the recorded signals were analysed to find parameters in the sEMG that could estimate the muscle fatigue. The median frequency (MDF) of the power spectral density (PSD) and the root mean square value (RMS) were used as spectral and temporal variables to assess fatigue. Decreasing trend was found for (MDF) with time as the biceps muscle fatigues, while the (RMS) did not express consistent tendency with the fatigue process. Least square regression line model were adopted for each variable to form an index for fatigue assessment. The subjects were classified according to this index at the three loads to check the ability of the MDF to evaluate the muscular fatigue for each individual.

A major problem in bioinformatics analysis or medical science is in attaining the correct diagnosis of certain importantinformation. For the ultimate diagnosis, normally, many tests generally involve the clustering or classificationMicroarray data classification is used primarily to predict unseen data using a model built on categorized existingMicroarray data. The applications of microarray technology are able to utilize information and knowledge from human genome project to benefit human health. In the last few years, the remarkable progress achieved in microarray technology domain has helped researchers to develop the optimized treatment of cancer. Human acute leukemia is used as test case to a generic approach to cancer classification, this classification approach is based on gene expression monitoring by DNA microarrays that distinct between acute myeloid leukemia (AML) and acute lymphoblastic leukemia (ALL). The objective of this research is to investigate and compare the accuracy, time to build model, and errors of classification process using Locally Weighted Learning (LWL) algorithm with nine different classifiers (Bayes Network learning, Conjunctive Rule, NBTree, Voting Frequency Intervals (VFI), Random SubSpace, Naïve Bayes Updateable, DIMM, Kstar, and PART); to previous tested datasets after performing some preprocessing to the datasets to enhance the classification process. The proposed approach and experiments showed that after conducting the preprocessing and the classification using Voting Frequency Intervals, Random Sub Space and Naïve Bayes Updateable algorithms through LWL approach it can be reached in 0.1 s time and accuracy of 94% which is outperform the other previous techniques for the same data when comparing with previous published studies.

The brain activity is a very complex process, which is mainly characterized by the electroencephalogram (EEG). Moreover, there exist many interactions between the brain and other human body systems such as the cardiovascular system. Therefore, to explore these interactions a model was identified based on intelligent modeling tools (fuzzy-ARX). Signals generated from a previous work related to the modeling of the cardiovascular system were used as an input for the proposed model. EEG signals were measured for six male subjects and were used as an output for the proposed model. The model output was validated in both time and frequency domains for each subject. Furthermore, the validation results revealed that there exist good match between the measured EEG signals and the corresponding estimated EEG signals generated from the proposed model for each subject. Moreover, the model could be used as a descriptor for the relationships existed between the brain and the cardiovascular system afferents.

Dr.eng. Consultant in materials sciences & materials applications, Egypt.
In these work ,the effects of laser irradiation on microstructure and performance of Ti6Al4VELI alloy have been studied by qualitative and quantitative analysis techniques, volume fraction of secondary phase, shape factors, number of particles of secondary phase, mean free path and grain size number were studied at different laser irradiation conditions. The effect of the amount of absorbed energy were represented by the variation in the number of pulses from 2000 pulses to 50000 pulses. Excimer laser irradiation is performed directly in the air and without any intermediate media. The volume fraction of the secondary phase b and α phase changed in the microstructure of Ti6Al4VELI alloy gradually with increase in laser dosages. Physical metallurgy considerations is the tool to understand the microstructure of any alloy system at specified laser irradiation conditions, the phase relationships and constitution of the system being studied.

Kamerlingh Onnes of Leiden University discovered Superconductivity (SC) in 1911. Two distinguishing properties of superconducting materials are zero resistance below a certain temperature and their ability to expel the magnetic field from inside. These properties enable a size and weight reduction of 50-70% in superconducting electrical equipment as compared to the conventional. SC has applications in many areas including military. Current military applications of superconductivity include electric power generation & distribution, mine protection & mine hunting, marine ship propulsion, radar and communications etc. The paper reviews the current state of military applications of superconductors and challenges (e.g. geometry, material properties, cryogenics, reliability and overall cost etc.) impeding the widespread use of superconductors in military applications. Recent developments suggesting the possible solutions to these challenges are discussed.

Hydrogels of natural and synthetic copolymers were gained a great attention in recent years. In this work, we aimed to prepare different copolymer hydrogels of Pectin/Acrylamide (PEC/PAM) and Pectin/Diethylaminoethylmethacrylate(PEC/DEAMA) using gamma irradiation. These hydrogels were studied and characterized by different techniques as, FTIR,TGA and SEM. The hydrogels were also, characterized in terms of gel content, and swelling at different pH and different temperature. The results showed that the gel fraction of PEC/PAM hydrogels decreases greatly with decreasing the contents of PEC and also the gel fraction increases with increasing irradiation dose up to 2.5 Mr then decreases with further increase of radiation dose. While for the PEC/DEAMA hydrogels, it is noticed that as the DEAMA content increases the gel content decrease. Water uptake percent was studied through the effect of temperature , it was found that the swelling of all the hydrogels changes within the temperature range 30–80 0C,it was found that water uptake percent increases as temperature increase for the system PEC/PAM and decreased for the system PEC/DEAMA. Also, waterup take studid as a function of pH within the pH range 2–8. Results prove that water uptake percent increases as pH increas for both systems. However, the swelling of PEC/PAM hydrogels was greater than the hydrogel based on PEC/DEAMA. The swelling kinetic studies showed that the swelling of all the hydrogels affected by the pH of the medium and the temperature and also, the highest percentage of swelling rate occurred at the first stagess of swelling time. The Pectin hydrogels was evaluated for the possible use in drug delivery systems. In this respect, the release properties of tetracycline HCL, as a model drug, was investigated. It was found that the percentage release from the hydrogels increase with time, and also the percentage release was examined at different pH values, where the highest release percentage occurred at pH8 for both copolymer systems.

Highly porous and interconnected styrene/acrylic-based porous materials were prepared by radiation-induced graft copolymerization of styrene/acrylic acid monomers onto surface of silica prepared from rice husk ash. The influence of synthesis conditions; such as irradiation dose, monomer concentrations and different solvents; were studied. It was found that the nature of the solvent had profound influence on the copolymerization reaction and water /ethanol mixture was selected as a suitable solvent for copolymerization processes. Graft copolymers of styrene/ acrylic onto silica surface was verified through Fourier Transform Infrared (FTIR) spectroscopy and Eenergy Dispersive Spectroscopy (EDX) was used to investigate the surface profile of representative copolymers by viewing the distribution of elemental nitrogen. ThermoGravimetric Analysis (TGA) and differential Thermal Analysis (DTA) of the copolymers were investigated. From the characterization of the prepared copolymer it was found that: copolymers of (styrene/acrylic)/silica are considerably different from each other, (styrene/acrylic)/silica based copolymers exhibited relatively more homogenous surface compared to (styrene/acrylic) copolymers. Water uptake percent increases as silica ratio increases to reach 24174 (mol/gm) and this prepared copolymer has a considerable capacity for adsorption of organic compounds and metals.

Lead-acid batteries are so important even in grid connected applications storage to improve system reliability. So, this is paper aims to address a new method of Electrical Parameters Estimations for this type of storage devices based on Performance Characteristics with the aid of Artificial Neural Network (ANN). To help designers, researchers and users in pointing the direction for indigenous research in electricity storage technologies. First, the parameters of the battery model are identified depending on curve fitting with the aid of improved Thevenin battery model, and the model is validated with a 12 V, 4Ah lead-acid battery Yuasa NP4-12 Battery. The model parameters and characteristics are well depicted in the form of 3D figures. Second, the ANN technique is used to estimate Thevenin Electric Model' parameters inthe form of ANN models with their algebraic equations. The proposed outputs for the models are: Discharging Resistance, Shunt Resistance, Back e.m.f. and Charging Resistance; each one is deduced with Battery Characteristics as inputs for every previous outputs: Charging/Discharging Rate, State of Charge, Time, Voltage, and Current. ANN models are created with suitable numbers of layers and neurons, which trained, simulated, checked and their algebraic equations are concluded accurately with excellent regression constant for all almost 1.

A dynamic model for a solid oxide fuel cell power plant has been constructed. The concept of a feasible operating area for a solid oxide fuel-cell power plant is introduced by establishing the relationship between the stack terminal voltage, fuel utilization, and stack current. By controlling the input hydrogen fuel in proportion to the stack current, constant utilization control can be accomplished. The effectiveness of the proposed schemes is illustrated through simulation.

This paper studies the design and performance of a WES / PFCS hybrid electrical power system. This system consists of Wind Energy System, WES, and Pem fuel cell system PFCS. The design of this system depends on the hourly energy balance technique. When the power output from WES, Pew , exceeds the load demand, PL , the exceed power usedby the alkaline electrolyser to produce hydrogen . Then the H2 is compressed and stored in pressurized storage tanks. Also, when Pew < PL this means that there is deficit power and the stored H2 is utilized for generation electrical power by the PFCS to overcome the deficit on the system. The methodology which developed here has been applied on EL-Zafarana site as a case study. EL-Zafarana is a remote site located at the coast of the red sea, Egypt.

This paper presents the design of operational transconductance amplifier (OTA) as a core building block of thecapacitive transimpedance amplifier (CTIA) for the implementation of infrared readout circuit on VLSI chips. The OTA has a two-stage amplifier which achieves low power and low noise. In addition, a voltage reference is designed for biasing theamplifier. Low power dissipation of the OTA is achieved by using of a supply voltage of 1.2 V and transistors operating in the subthreshold region. The designed OTA, built in standard 0.13 μm CMOS technology, dissipates 3.2 μW of power with input referred noise of 52.1 nV/√Hz@1KHz. Also, the OTA has a common mode rejection ratio of 81 dB and input offset voltage of 5.089 μV. This is accomplished by the efficient sizing of the used transistors together with a compensation capacitor.

Pressure sensing in harsh environments poses many difficulties. The major challenge is implementing a sensor interface circuit capable of operation at high temperatures ( 300°C) for extended periods of time. Conventional, siliconbasedelectronics are not suitable for operation in such conditions due to their sizable leakage currents and junction instability. Inthis work, a wireless solution based on silicon carbide electronics is presented. The proposed solution follows a simple design procedure and exhibits robustness to the large process variations typically associated with silicon carbide technology.

New Advanced IHS for Pansharpening of Hyperspectral Image

Lecturer, Egyptian Air Forces.
Image fusion techniques have been developed to utilize different types of image data. The aim of image fusion is to improve the quality of the information by combining two or more different types of images. Pan sharpening is one of the most common fusion techniques used for its efficiency and simplicity. It fuses a cube of multi/hyperspectral image of low spatial resolution with a panchromatic image (PAN) of a higher spatial resolution to obtain an image with high spectral and spatial resolution. This requires a transformation tool to separate the spatial information of the cube from its spectralinformation. Some of these transformations include Intensity-Hue-Saturation (IHS), principle component analysis (PCA), wavelet transform (WT) and independent component analysis (ICA). IHS is considered the most popular transformation tool because of its simplicity and efficiency. IHS introduces a fused image of high spatial resolution but it suffers from some spectral distortion. In this paper, we tried to solve this problem by using an adaptive image coefficient and a morphological edge detector with the original IHS transform. From experimental results, depicted in this paper, thenew proposed IHS fusion method produced images of high spatial resolution with minimal spectral distortion compared to the original and adaptive IHS pan sharpening.

Joint Photographic Experts Group (JPEG 2000) is an image compression standard which is recently became one of the most used techniques in image transfer, especially for satellite images. Unequal Error Protection (UEP) coding techniques can be used to increase image transfer immunity against channel noise. In UEP, the important parts of the image areprotected using stronger codes than that used for the other parts. This paper proposes an UEP scheme by applying Low Density Parity Check Code (LDPC) for protecting the Region Of Interest (ROI) and headers (markers and marker segments) and Hamming code for protecting compressed data bits. A digital communication system which incorporates a Binary Phase Shift Keying (BPSK) as a common modulation technique is built for the purpose of verifying the proposed UEP scheme performance. The performance of the proposed UEP scheme is compared subjectively and objectively, to validate its superiority, with the traditional Equal Error Protection (EEP) scheme.

All-silicon’ Tunable Cavity Filter Technology for Software Defined Radios
Muhammad Arif
1
National University of Sciences and Technology, Pakistan.
The idea of software defined radios (SDR) has now been around for several years and there have been extensive efforts in this field especially for military communications. The vision is to have a single reconfigurable radio with multi-band and multi-standard compatibility that can operate effectively in dense electromagnetic radiation environments while having the frequency agility needed to communicate using multiple waveforms in rapid succession. The development of a truly reconfigurable, next-generation SDR is still far from complete. One key area requiring innovation is its reconfigurable RF front-end (RFFE) design, mainly due to the non-availability of a technology for realizing a low-loss, compact, and continuously-tunable broadband filter with low power consumption. In this lecture, the performance of the existing tunable filter technologies will be briefly discussed in the light of SDR requirements. It will be shown that while every technology has its merits and limitations, a common shortcoming is the lack of a simultaneous low-loss (high unloaded quality factor ‘Qu’) and high tuning ratio while keeping a mobile form factor. Finally, a new “all-silicon” tunable cavity filter technology will be introduced. This all-silicon tunable filter technology exploits the precision associated with micro-fabrication, along with the accurate movement of integrated RF MEMS to demonstrate a simultaneous low-loss (Qu ≥ 1000) and wide tuning (≥ 1:2) filter. The performance of some technology demonstration devices will be presented to show that this all-silicon filter technology provides an appropriate solution for realizing compact, low cost, system-on-chip (SoC) compatible RFFE suitable for microwave SDR applications.

Prognostics and Health Management (PHM) - State-of-the-art in Predictive Maintenance
Manzar Abbas

National University of Sciences and Technology, Pakistan.
With the growing advancement in sensor technology and automated controls in engineering systems, trend of on-board data recording has greatly increased. The data analysis tools along with the real-time sensor data, have resulted in a paradigm shift in the way systems are maintained. After the industrial revolution, the first generation of maintenance philosophy was corrective maintenance, in which, components or systems were fixed once they got failed. In safety critical systems, this maintenance philosophy produced catastrophic results. The next generation of maintenance philosophy was preventive maintenance, in which maintenance was performed based on the manufacturer's or OEM specified life. Although, this maintenance philosophy has been able to achieve better results in terms of safety, however, in perspective of life-cycle costs, preventive maintenance philosophy is wasteful. Therefore, a few decades back, the concept of predictive maintenance became popular. Ever since it came into being, predictive maintenance has gone through several evolutionary stages. Reliability centered maintenance or RCM, makes calculated estimates of maintenance schedules based on the archived statistical data from the field. With the development in MEMS sensor technology, Condition-Based Maintenance (CBM) using real-time data has become the prevalent maintenance philosophy. The recent advances in data processing technologies have enabled us to determine not only the present health but also to predict the future health of systems. In other words, system's health is can not only be estimated but health can also be managed. Therefore, another phase of predictive maintenance, that is Prognostics and Health Management (PHM) has evolved. In PHM, two key modules are fault diagnostics and failure prognostics. In fault diagnostics, the current health of the system using sensor data is estimated, while in failure prognostics future evolution of health is predicted. This lecture consists of a review of fundamental concepts of fault diagnostics / failure prognostics, which will be followed by the tools and techniques used to develop PHM algorithms. The lecture also includes a review of the state-of-the-art in this field. A few case studies related to fault detection / prediction in aircraft engine, electromechanical and electrochemical domains will also be discussed.

Analog Design-Assist CAD Tools in the Nanometer Era
Mohamed Dessouky

Ain Shams University, Egypt.
With the advance of nanoscale fabrication processes, analog design is facing new challenges resulting from the associated complex processing. A new set of systematic mismatch effects appears due to layout. This includes shallow trench isolation stress, well-proximity and lithographic effects to name a few. The demand for new analog design-assist CAD tools is increasing. Such tools would simplify the task of the designer in order to achieve a successful analog and physical circuit design. The target is not full design automation, but rather design assistance on specific problems. In this paper, three directions are discussed; first, complex layout templates are introduced to simplify layout design, then electrical design for manufacturing (E-DFM) is suggested to treat parametric yield issues arise from manufacturing process variation and layout issues, and finally automated circuit design migration is described to facilitate design porting needed for the accelerated pace of process scaling and time-to-market.

Potential of Renewable Energies and Strategies to use them
Hani El Nokraschy

Nokraschy Engineering, Germany.
A glance at the possible renewable energies in the world gives immediately the impression that their potential is probably sufficient to cover the global demand of humanity, for example: the deserts of the world receive in 6 hours more energy from the sun than the humanity consumes in a year. The reason that this huge potential was not used efficiently till now lies in the absence of technologies to convert the available natural energy to a useful form like electricity. Since about 40 years several technologies immerged that can convert efficiently natural energies to electricity, overcoming the problems of natural fluctuations is still a challenge. The presentation describes a method to convert direct sunrays, all year available in desert regions, to high quality electricity that can be supplied on demand at any time. The key issue is that the sunrays are concentrated on a focus, thus obtaining the advantage of deploying both main components of the sunrays: light and heat. Heat, when concentrated, can reach temperatures of several hundreds degrees centigrade, which is consequently stored in a mixture of molten salts. The stored heat energy – equivalent to an oil tank - is then used to generate steam - equivalent to a fossil fired boiler. The steam drives in turn a conventional steam turbine, just on demand, day or night and especially in the peak hours. The costs of such technology are affordable since no fuel will be purchased, more over no negative effects will occur from emissions.

Cairo University, Egypt.
With the continuous increase in energy demand in Egypt (7% annually), the depleting available fossil fuels may not be able to cover the future energy needs on the medium and long terms. The Greenhouse gas emissions resulting from fossil fuel burning has also become a major concern. Additionally, Egypt is facing the problem of shortage of fresh water needed for irrigation and human use, which has reached water poverty levels. On the other hand, Egypt possesses a huge potential of renewable energy including solar, wind and biomass energies. Such Energy and Water challenges facing Egypt could be met by proper large scale utilization of the available Solar, wind and biomass energy resources. Educational and Research programs in Renewable energy are essential for preparation of skilled work force capable of handling large RE projects and for developing local knowhow for local manufacturing of Renewable Energy Systems and Components. Undergraduate and graduate Educational programs should be formulated to include all needed skills including technical knowledge, economics, management, policy and intercultural skills and will facilitate integration with large interconnection projects and initiatives such as DESERTEC and MSP. Jointresearch and development activities between local and foreign research institutions could also facilitate collaboration in local manufacturing of components and systems for utilization of Renewable Energy and could lead to a sustainable energy and fresh water supply for Egypt on the medium and long terms. Different programs and initiatives paving the way to large penetration of Renewable Energy in the future energy mix are reviewed.

Renewable Energies as one of the Saviors
Mohamed Elsobki

Cairo University, Egypt.
The core idea is to have an allocation/quota obligation for using electricity generated from renewable energies by a certain group(s) of activities and increasing this obligation on periodical basis. The size of the allocation/quota obligation would be governed by the actual available electricity from renewable energies. This can be referred to as a pulling scheme for developing renewable energies; where the demand and its development is being guaranteed by a legislation that enforces the allocation/quota obligation. For the case of Egypt, the current available electricity from renewable energies, other than hydro, amounts to one percent from the electricity generation mix. This corresponds to three percent of the electricity use by all the Industrial end users at all voltage supply levels. It is being proposed that industrial users would be the flagship for implementing the proposed allocation/quota obligation. The simulated results for the implementation over nine years shows the possibility of achieving more than five Giga Watt of electric generation capacity andover than twenty five percent of the electric energy from renewable sources being used by the industrial sector. Other eligible end users to join the implantation of the proposed scheme would be the tourism, street lighting and commercial sectors, in view of their current electricity tariffs. Legislation (preferably a law) needs to be in place to activate that allocation/quota obligation scheme. Its implementation can be immediate as it is based on allocation of renewable energies through accounting systems.

Nuclear Research Center, Egypt.
Desert development is the key countering urban crowding in a country like Egypt. Although the Nile Valley accounts for just four percent of Egypt's surface area, with expected population to be doubled by 2050. Western desert in Egypt is a part of the great Sahara with a very hard climate to start a agricultural community for its arid conditions. In Egyptian desert of Alamin (N30" 17'21.9" E 028 40'4") 300 km from Cairo. A pump of 82m3/h peak were installed. The area of 7'000 Feddan (Fed=4200m'; was reclaimed and prepared to cultivate Jojoba plants. This major project is a pioneer one for the producing is a shrub native to the Sonoran and Mojave deserts of Arizona, California, and Mexico. lt is the sole species of the family Simmondsiaceae, placed in the order CaryophyllalesJojoba is grown for the liquid wax (commonly called jojoba oil) in its seeds. This oil is rare in that it is an extremely long (C36*C46) straight-chain wax ester and not a triglyceride. Jojoba oil is easily refined to be odorless, colorless and oxidatively stable, and is often used in cosmetics as a moisturizer and as a carrier oil for specialty fragrances. The systems were designed and assembled by Egyptian specialists and supervised by good reputed research centers and professors. System with 30 kW submersible pump has a motor 30-60 Hz, 3 Phases, 380 V, the inverter has a very good control unit and protection circuits. Nokrashy (2006) declared that Egypt should target a RE-share of 30% in year 2020 asit has now already 16% (including hydro energy from the dams on the Nile,Mueller et al., (1998) started a small scale farm (two hectare) irrigated with solar powered irrigation system using photovoltaic generator. The Future shows a great need to maintain the same topic except the generator should be a small scale CSP general.
