Developing an Electronic Payment System (EPS) for universities to handle tuition payment is a complex task since factors such as stakeholders problems, culture, cost and communication infrastructure must be addressed in finding system solutions. This paper presents a framework for developing such a system by highlighting the development methods and the model for system solutions. The proposed system has been implemented and used by nearly ten thousand users (students and parents). The results of the evaluation (based on the KSF defined) indicate that the proposed system has achieved all of the target indicators. Read More Read Less

Abstract This paper presents a new topology of drive circuitry for variable reluctance stepping motors (VRSM) for improving the performance of such motor by modifying its time constant and thus, increasing its stepping rate. Therefore, the initial torque developed by the motor is high; the switching from one coil to the next is faster than normal and consequently, the rotor moves... This paper presents a new topology of drive circuitry for variable reluctance stepping motors (VRSM) for improving the performance of such motor by modifying its time constant and thus, increasing its stepping rate. Therefore, the initial torque developed by the motor is high; the switching from one coil to the next is faster than normal and consequently, the rotor moves as quickly as it should be. The circuitry discussed in this paper is connected directly to the motor windings and the motor power supply, and this circuitry is controlled by a digital system that determines when the switches are turned on or off.

Abstract Many authors considered measuring (e-) readiness of their educational training systems. Then, they employed either regression or factor analysis methods to model impact of factors or variables on (e-) readiness of their educational systems. This article suggests employing the sophisticate and well developed structural equation modeling (SEM) to model impact of other factors on (e-) readiness of a given educational... Many authors considered measuring (e-) readiness of their educational training systems. Then, they employed either regression or factor analysis methods to model impact of factors or variables on (e-) readiness of their educational systems. This article suggests employing the sophisticate and well developed structural equation modeling (SEM) to model impact of other factors on (e-) readiness of a given educational training system. An application for a hybrid training system for Probability and Statistics for Engineers has been given. Read More Read Less

Abstract Despite Aspect Oriented software development (AOSD) improve existing paradigms of development, by providing explicit mean to model crosscutting concern (aspect), the complexity of interactions among aspects and between aspects and base modules still a difficult problem that may reduce the value of aspect-oriented separation of cross-cutting concerns. The need of developing efficient techniques that permits us identification and analysis of... Despite Aspect Oriented software development (AOSD) improve existing paradigms of development, by providing explicit mean to model crosscutting concern (aspect), the complexity of interactions among aspects and between aspects and base modules still a difficult problem that may reduce the value of aspect-oriented separation of cross-cutting concerns. The need of developing efficient techniques that permits us identification and analysis of interactions between aspects, rise and grow. In this paper we propose a technique that allows the user to analyse interaction between aspects, detect and resolve conflicts between them based on the search of Hamiltonians paths. The technique is based specification it use the specification of composition of aspects to analyse aspect and produce rules of composition and it is supposed generic in fact, that exploits the dependencies generated by the operators such as before, after, around and replace . Also, our contribution will be at aspect oriented requirement engineering (AORE) since, it is desirable to early possible identify aspect and analyse interactions too. The technique is illustrated through examples. Read More Read Less
