We present a novel approach for the measurement of one-way delays and throughput between network nodes in heterogeneous environment over Wide Area Network (WAN). This research investigates performance evaluation of remote data transfers on heterogeneous services and technologies environment. We propose an enhanced equation to evaluate the performance of(More)
Research in program understanding is motivated by two different reasons. One group of researchers are from the cognitive psychology group and their main interest is to find out exactly what knowledge and understanding expert programmers have that novices don’t. Another group of researchers are from the software maintenance group whose main aim is to build(More)
Real-time virtual heritage application is normally executed with a high performance computer system. This is due to the complexity and highly computational cost which makes such system impossible to run in a lower specification computer system. Therefore, many developed virtual heritage application cannot be retrieved by the target users. One of the factors(More)
This paper presents a method for fast-approximate collision detection between 3D models <i>S</i> undergoing rigid body motion. To enclose a 3D model in as tight as possible, we propose an approach known as oriented convex polyhedra <i>R</i>(<i>S</i>). By surrounding the 3D models tightly, the veracity of detected collision can be improved. It is known that(More)
Eliciting requirements for a system is an important activity in requirement engineering. This process occur at the early stages in system development which involves communication between customers and developers. Researchers have identified that poor communication is one of the most common problem in identifying and defining customer’s requirements. This(More)
This paper presents complete network analyzer development for heterogeneous services in a campus environment. The purpose of this study is to define the accuracy of network analyzer development with independent data, real networks and OPNET simulation tools. The tests for network analyzer software are based on traffic and utilization performance. The(More)
The problem of learning programming subjects, especially through distance learning and E-Learning, has been widely reported in literatures. Many attempts have been made to solve these problems. This has led to many new approaches in the techniques of learning of programming. One of the approaches that have been proposed is the use of virtual pair(More)
Wiki is a social networking system that allows users to freely intermingle at different levels of communication such as collaborative learning, chatting and group communications. This is conceived to be the merriest goal. It is particularly vulnerable due to its features of open medium and lack of clear plan of defense. Social networking systems today are(More)
