Elasticity should be treated as a first class system parameter. Particularly in large cloud environments, elastic applications would benefit if the underlying infrastructure provided primitives for elasticity and were themselves elastic. If you want to provide an elastic service and the cloud does not provide good primitives for the degree of elasticity you require, then you are forced to over-...

Critical Success Factors (CSFs) are used to support and evaluate the success of a strategic and tactical approach in project implementation in order to increase the probability of success. This system is used by executors in project delivery to achieve improved performance capabilities with limited resources. The present paper aims to identify the impact of CSFs amongst the main elements involv...

The success of the World Wide Web has broaden the way for general distributed computing using a large set of heterogeneous computers. Unfortunately the resources made available on the Web are almost information only and interaction between users is limited to a few special applications. A Web Operating System (WOS) 8] tries to provide solutions for this problem and generalizes the use of diiere...

As networks of workstations (NOW) emerge as a viable platform for a wide range of workloads, a new scheduling approach is needed to allocate the collection of resources across competing users. In this paper, we show that extensions to a proportional-share scheduler for improving response time can still fairly allocate resources to a mix of sequential, interactive, and parallel jobs in this dist...

Making educational material be available on a network cannot be reduced to merely implementing hypermedia and interactive resources on a server. A pedagogical schema has to be defined to guide students for learning and to provide teachers with guidelines to prepare valuable and upgradeable resources. Components of a learning environment, as well as interactions between students and other roles ...

The rich Islamic resources related to religious text, Islamic sciences, and history are widely available in print and in electronic format online. However, most of these works are only available in Arabic language. In this research, an attempt is made to utilize these resources to create interactive web applications in Arabic, English and other languages. The system utilizes the Pattern Recogni...

The prevalent ADSL service facilitates simultaneous use of telephone and high-speed data communication services. It is one of the best choices in current network technology for local loops. In this paper, we present solutions to design an interactive true video-on-demand (ITVOD) system for ADSL services with scarce resources at the set-top box. In the proposed system, we not only provide intera...

metadiscourse is a widely used term in current discourse analysis and language education, referring to an interesting, and relatively new approach to conceptualizing interaction between text producers and their texts and between text producers and users. despite the growing importance of the term, however, it is often understood in different ways and used to refer to different aspects of langua...
