The advances in communication technology stands for the need of compact size, easy to fabricate microwave devices. Herein, we propose a robust, tunable, band-pass filter, operating in the X-band (9.1 GHz). Metamaterial based on split-ring resonators (SRRs) is suggested to implement the proposed filter. The proposed design showed an improvement of 84% and 58% in the insertion loss (0.348 dB) and reflection loss (23.8 dB) respectively with respect to previous publications. In addition, the filter provided an acceptable sharpness to be utilized in radar applications. A tunability in the resonance frequency can be easily reached by changing the SRRs gap where a frequency range between 8.62 GHz and 9.46 GHz can be tuned. A fabricated filter is demonstrated where the mismatching between simulation and experimental results is justified.

current source inverter (CSI) requires particular modulation strategy due to its configuration and principle of operation. An overlap period of time between the switching states is necessary so as not to cut the input inductor current. When operated by space vector pulse width modulation (SVPWM), this overlap instant results in current harmonic distortions. The current distortions deteriorates the quality of electric power delivered by CSI. The following paper introduces a comparative study between five and seven segment modulation sequences of SVPWM, and investigates their effect on the current distortions resulted by the overlap instant. The study finally recommends one modulation sequence over the other to alleviate the impact of the overlap instant on the output current waveform.

This paper presents a compact broadband rectenna for harvesting RF energy in WLAN and WiMAX applications. A coplanar waveguide (CPW) rectangular monopole antenna loaded with double inverted-L strips is designed as the receiving antenna. By using an inverted-L open circuited stub as an input matching network, a compact rectifying circuit based on the voltage doubler principle is proposed, which has broadband performance. The receiving antenna and the rectifier are simulated using CST and ADS software packages, fabricated using photolithographic technique, and measured. The antenna is operating from 1.83–3.58 GHz (bandwidth of 1.75 GHz), and 5.4–6 GHz (bandwidth 600 MHz). These bands cover different wireless applications such as: GSM 1800, UMTS 2100, IEEE 802.11b&g WLAN systems, 3.5 GHz WiMAX system, and the IEEE 802.11a WLAN system. The antenna gain reaches 4.2 dBi at 5.8 GHz while the radiation efficiency is 99.6 %. The measured rectifier conversion efficiency reaches 29.72 % at 6 dBm input power while the measured total rectenna power conversion efficiency is 27.725 % at a frequency of 3.5 GHz.

The main role of batteries which used as a secondary power source in any spacecraft is to supply power to the satellite under the condition of shadow or the inability of solar-PV arrays to feed the satellite loads with power. In this paper, model and control of a charge/discharge unit (CDU) of the battery in low earth orbit satellites is developed. The proposed CDU control algorithm regulates the satellite bus voltage within the standardized levels. Furthermore, the CDU control is tested against various disturbances to verify the proper operation of the unit.

Developing an online handwriting recognition system for Arabic script used in pen-based devices plays an important role in making these devices available and usable for the Arabic society. This paper develops a preprocessing algorithm for strokes written in Arabic script to improve the strokes recognition process, since there are some troubles on distinguishing the written stroke from similar characters. The uniqueness of the recommended preprocessing algorithm is the dealing with every stroke in the character separately. The algorithm is comprised of five essential phases that will settle on the strokes prepared and make the strokes ready for the next phase in recognition. Before the preprocessing algorithm, a basic step called stroke capturing is done, where data points are collected along the path of an input device (stylus pen or mouse) same time those characters are drawn.

This paper presents the high performance control of PMSM drive system implementation based on DSP real-time controller. The high performance drive is used in applications that need to high precision accuracies such as CNC machines and servo applications. The proposed high performance PMSM drive system consists of PMSM, three-phase voltage-source inverter based on space-vector pulse-width modulation (SVPWM), field-oriented control scheme, intelligent fuzzy logic speed controller and PI current controllers. The PM servo motor is controlled to produce a constant torque through changing the voltage/frequency ratio. The three-phase inverter based SVPWM technique supplies the PMSM with a high voltage and low harmonics. The proposed drive system is based on indirect field-oriented control to decouple the torque and flux currents which mimic the behavior of the DC-machines. The advantages of Fuzzy Logic Controller (FLC) overcomes the slow response and tuning problems of the conventional PI speed controllers without any mathematical calculations. The Dspace Real-Time controller is used to solve the control programs. The different parts of the proposed drive system are designed and tested. The advantages of the proposed drive system are confirmed by the practical results.

Cloud computing is one of the largest developments in the field of information technology during recent years. It is a service oriented computing which offers everything as a service via the internet by the pay-as-you-go model. It becomes more desirable for all organizations (such as education, banking, healthcare and manufacturing) and also for personal use as it provides a flexible, scalable, and reliable infrastructure and services. For the user, the most important issue is to store, retrieve and transmit the data over the cloud network and storage in a secure manner. Steganography and cryptography are some of the security techniques applied in the cloud to secure the user data transmitting. The objective of steganography is to hide the existence of communication from the unintended users; whereas cryptography encrypts the data to make it more secure. Steganography is considered as the most effective technique for securing the communication in the cloud. Digital images are most commonly used as a cover medium in steganography. In the literature, there exist several image steganography techniques for hiding information in images; which were developed and implemented in the time domain as well as in the frequency domain. Fundamentals of spatial domain and frequency domain techniques are reviewed in this paper with emphasis on the Least Significant Bit (LSB) and the Discrete Cosine Transform (DCT) techniques.

Nowadays, Plug in Electric Vehicle (PEV) has been considered as an environmental friendly and high efficient than the fuel vehicle. The electric vehicle (EV) has two main electrical systems; the on-board battery charger (BC) and the motor driver. Basically, there are two types of charger depends on the power flow; unidirectional and bidirectional BC. The EV which has a bidirectional BC is considered as a decentralized generator, wherein it could supply the grid while the vehicle is connected. Thus, bidirectional BC is very beneficial feature for both the EV driver and the grid operators. In this paper an updated review is presented about the single-phase bidirectional BC. The review is compromised on four main parameters; the BC lifetime which based mainly on the capacitor type, efficiency, cost and the power factor (PF). In addition, the topologies are summarized regarding various performance criteria.

The continuously increasing energy demands, and running out of the conventional fossil fuel have directed research towards developing renewable energy resources. Whereas, the industrial power electronics represents crucial part of the renewable energy conversion system. The energy efficiency possesses various challenges for the design of interfacing inverter. This paper presents a systematic approach for practical design and component selection for multilevel inverters in photovoltaic (PV) systems. The study includes the practical considerations of different sites of installations, PV cell modelling, technologies of various power electronic devices, accurate power losses modelling of power electronic devices and weighted efficiency prediction with considering practical mission profiles of the PV system. The traditional silicon (Si) insulated gate bipolar transistor (IGBT) is compared with silicon carbide (SiC) metal oxide semiconductor field-effect transistor (MOSFET) and gallium nitride (GaN) wideband gap (WBG) technologies. The proposed methodology is beneficial for PV system planners for evaluating technical and economic installations of PV systems. Moreover, optimized selection of power components and technologies can be easier using the proposed method.
