The induction motor is widely used in industrial applications, respectively, the fault detection and isolation is very important for the continuity of industrial process. The stator turns faults are one of the common faults that may lead to a massive failure which confirms the early detection of the fault to take the best action. This paper presents the fault diagnosis of stator turns faults using extended Kalman filter technique to estimate the percentage of short circuit turns ratio in each phase. The simulation is implemented using MATLAB/Simulink, the technique is tested in various load conditions. The simulation results show that the proposed technique is effective and robust, it shows an accurate estimation in the presence of noises to take action prevent the propagation of fault.

Recently, Developing Internet of Things (IoT) devices has been one of the most important products in the technology industry. Most of IOT products are designed based on System on chip (SoC) platform that allows producing faster and higher system level efficiency products. The Software Develop System-on-Chip (SDSoC) is a C/C++ development environment used to create hardware-software co designs on a heterogeneous FPGA-CPU platform. The questions of what platform and what implementation, whether hardware or software is best suited for more efficient platform. In this paper, these questions are sought to be answered through analysis scenarios of hardware and software implementation using SDSoC tool. This paper introduces a different platforms implementation for hardware-software co-design of turbo encoder synthesized by SDSoC. The turbo encoder widely used in various wireless communication standard such as the 3rd Generation Partnership Project (3GPP). The purpose of this paper is to select platform that achieves performance metrics such as area and power. In addition, new metric was defined to select platform that achieves the best performance‥

In this paper, a bottom-gate bottom-contact (BGBC) Organic Thin Film Transistor (OTFT) has been fabricated using TIPS-Pentacene as a semiconducting layer, PVP as a dielectric, and Silver nanoparticles as gate, source, and drain electrodes. The whole fabrication process has been conducted in open air environment, the deposition of the silver electrodes has been performed by using a SonoPlot GIX Microplotter (which uses plotter-printing technique), and the semiconductor and dielectric layers are deposited using spin-coating. Plotter printing is one of the auspicious ways of procuring small-size features of printed elements. The characteristics of the fabricated OTFT has been discussed, with a mobility of 0.03cm2/V.s, and a threshold voltage of −11V.

Language Tutoring Systems (LTSs) are computer-based tutoring systems that address linguistic skills. Most LTSs rely on Natural Language Processing (NLP) tools for analyzing the student's answer to support him/her with appropriate feedback. In such systems, diagnosing the student errors is typically based on a large library of students' expected bugs. In addition, such systems (especially in case of the Arabic language) don't consider modeling of the student knowledge or assigning difficulty levels to the presented questions. Subsequently, such systems do not support individualization of their interactions to each student's needs and preferences. This paper presents the Arabic Grammar Tutor (AGTutor), which utilizes Constraint-Based Modeling (CBM) to model the domain eliminating the need for the bugs' library. Grammar rules are represented as a set of constraints that are categorized in terms of the different linguistic skills. Linguistic skills are classified into several levels and categories. Such hierarchical structure allows diagnosing the student errors in a more efficient way. In addition, modeling the student competence in the Arabic linguistic skills is also expressed in terms of a set of domain constraints. Assigning difficulty levels to each question according to the required skills and modeling the student knowledge allow the system to adapt its interactions according to the student week points to enhance his/her Arabic linguistic skills. Evaluation results have shown the effectiveness of AGTutor in tutoring the students and the satisfaction of both the students and the teachers with its features and capabilities.

This paper concentrates on developing efficient and robust backward solution for the forward sparse greedy algorithms and applies it in the field of speech compression. All existing backward solutions are based on constraining more and more weights to zero while re-optimizing the remaining nonzero weights to compensate. Our approach is termed Sparse Vector to Sparse Matrix (SVtSM) algorithm and its idea is to replace the k-sparse weights vector with a k-sparse symmetric matrix. The key result of this paper showed that, the replacement approach proved its effectiveness in achieving significant compression ratios at different SNR levels, and to work efficiently than the backward elimination algorithms.

This paper presents a new generic approach for the derivation and implementation of feedback gains of automatic control systems using symbolic-based representation of feedback stabilization functions. The derivation part is based on the exact mathematical symbolic-based formulation of the control problem, where feedback gains are derived in a symbolic form function of system symbolic parameters and assisted by appropriate symbolic-based programming. On the other hand, the symbolic feedback functions realization is implemented using embedded symbolic-based configuration using functional programming. The proof of concept of the suggested approach is successfully demonstrated thru the derivation and implementation of symbolic-based feedback stabilization of a case study of forth-order inverted pendulum problem. Finally, the results of experimentations of the case study are depicted comprising executing embedded symbolic-based functions using micro-controller/Proteus simulation program configuration equipped with functional programming facility for feedback gains expressions executions.

Recently, Maximum Power Point Tracking (MPPT) algorithms plays an important factor in optimizing the output power obtained from wind Energy Conversion Systems (WECS). Following MPPT techniques ensure the extraction of maximum possible power during wind speed variations while satisfying changeable or constant load requirements as well as battery charging operations. It is well known that when wind speed changes; the power extracted from the wind turbine changes accordingly. Because of that, the implementation of a robust and effective MPPT algorithm in the power converter becomes necessary to keep the output power at its maximum value irrespective of any sudden change in either wind speed or load. This paper presents a novel MPPT algorithm based on optimization of converter duty cycle values. The main idea is to build a mathematical model which relates the optimal duty cycle according to wind speeds. This model has been built based on simulations of a standalone low-cost WECS consisting of wind turbine, permanent magnet synchronous generator (PMSG), uncontrolled rectifler, DC/DC buck converter and constant load. The WECS have been simulated based on variable wind speed. The duty cycle values have been selected while monitoring and recording the output power. Then, the model has been built based on the optimal duty cycle which ensures the successful achievement of the MPP operation at specific wind speed. The results obtained have shown improved and acceptable performance of low-cost WECS in terms of MPP operation achievement and tracking time.

The harmonics are considered a problem for power system. The problem is present when Thyristor Controlled Reactor (TCR) is used as a poor factor correction technique. This paper gives a study for reduction of harmonics which produce from TCR. Actually, the TCR system is not exist as a standalone compensator but combined with other configuration such as Fixed Capacitor (FC), Thyristor Switching Capacitor (TSC), Mechanically Switched Capacitor (MSC), and the filter. The model in this paper consists of a TCR combined with a FC. The model of TCR may be connected in star, delta, and hybrid. Sources of regular and irregular harmonics will be discussed. Many techniques will be introduced for reducing the harmonics. 12-pulse technique (Hybrid) is shown as one effective method to suppress that harmonics. The simulation result will be displayed for RL load at the different topologies of the TCR under condition keeping the same rating for the reactive power of TCR.

This paper introduces a Maximum Power Point Tracking (MPPT) controllers for Wind Generation System (WGS) based on a small-scale low cost application. The MPPT algorithm has been developed based on Hill climbing technique. Two controllers have been designed using Proportional and Integral (PI) control and Sliding Mode Control (SMC) scheme. Using back-EMF observer, the rotational speed has been estimated in of the controller while the speed is measured in the other one. Both the controllers are independent of a wind speed measurement. This paper develops a dynamic model of the WGS in the dq reference frame. MATLAB/SIMULINK has been used to analyze the behavior of developed controllers. As a final point, an evaluation of the suggested controller with the classical controller in terms of dynamic performance
