This paper presents a review for the characteristics of solar resources in 32 sites across Saudi Arabia through determining the performance of a pilot photovoltaic system based on real time solar radiation data collected during the last two years. The investigation has been done for three possible of sun tracking modes: fixed tilt angle, 1-axis and 2-axis tracking modes. The performance characteristics have been determined using three indicators: yield factor, capacity factor and performance ratio. The simulation results showed high energy productivity for all the 32 sites over Saudi Arabia. The values of performance indicators are high compared with similar systems in different countries. The main purpose of this study is to explore the relative properties for some sites in Saudi Arabia regarding solar energy production. [ABSTRACT FROM AUTHOR]

The rapid development in Internet technology and its big popularity has led some universities around the world to incorporate web-based learning in some of their programmes. The present paper introduces a comprehensive survey of the publications about using remote laboratories in electrical engineering education. Remote laboratories are web-based, real-time laboratories that enable students to measure and control the measurements remotely in their own time. The survey highlights the features of many recent remote laboratories and demonstrates the software and networking technologies used. The paper provides a comprehensive overview on several aspects related to remote laboratories development. The paper concentrates on the publications appearing during the last decade. The review is arranged according to the area of specialisation, then chronologically. [ABSTRACT FROM PUBLISHER]
