the operation of a distribution system in the presence of distributed generation systems has someadvantages and challenges. optimal sizing and siting of dg systems has economic, technical, andenvironmental benefits in distribution systems. improper selection of dg systems can reduce theseadvantages or even result in deterioration in the normal operation of the distribution system. dgallocation ...

Amobile ad hoc network (MANET) is a wireless communication network which does not rely on a pre-existing infrastructure or any centralized management. Securing the exchanges in MANETs is compulsory to guarantee a wide spread development of services for this kind of networks. The deployment of any security policy requires the definition of a trust model that defines who trusts who and how. Our w...

This study investigates the factors affecting the brand loyalty of the customers of Auto-mobile industry in region of Pakistan with the use of ECSI model. A well-organized structured questionnaire was distributed among the customers of Auto-mobile industry. The questionnaire was based on 5 Point likert-type scale. Results show that the customer expectations have a direct positive impact on perc...

Mutual Exclusion in a fully distributed computer system contains a lot of complexities related to the solution design and its implementation. A number of solutions have been proposed for solving mutual exclusion problem for fully distributed environment but most of them are related to higher message passing overheads over the network, which causes low performance and efficiency. In this paper a...

This paper presented a fully distributed algorithm to compute a planar subgraph of the underlying wireless connectivity graph. This work considered the idealized unit disk graph model in which nodes are assumed to be connected if, and only if, nodes are within their transmission range. The main contribution of this work is a fully distributed algorithm to extract the connected, planar graph for...

Multimedia distributed systems deal with heterogeneous data, such as texts, images, graphics, video and audio. The specification of temporal relations among different data types and distributed sources is an open research area. This paper proposes a fully distributed synchronization model to be used in multimedia systems. One original aspect of the model is that it avoids the use of a common re...

This paper presents a distributed N-body method based on an adaptive collaborative system model. The collaborative system is built with the distributed objects in a cluster. It can be reconfigured during the computation to fully utilize the computing power of the cluster. The method is implemented in Java and RMI to support distributed computing on heterogeneous platforms. A distributed tree st...

Online delivery of programmes of Higher Education typically involves a distributed community of students interacting with a single university site, at which the teachers, learning resources and administration of the programme are located. The alternative model, of a fully ‘Virtual University’, which assumes no physical campus, poses problems of resource provision, recognition and accreditation....
