Distributed and Collaborative Learning Objects Repositories on Grid Networks
نویسندگان
چکیده
The paper deals with the design and a prototype implementation of a collaborative repository of scientific learning objects based on an efficient mechanism of filing and retrieving distributed knowledge on the Grid. The proposed repository can deal with a large variety of different learning contents. Its prototype implementation, developed for Chemistry contents, is part of an extended architecture consisting of a federation of autonomous local repositories. The federation is led by a coordinator who keeps track of the repository in which the learning objects are directly stored or referenced. In each repository server, a locally hosted Web Portal allows a easy management of the repository through a CMS front-end.

The interactions among peers in Peer-to-Peer systems as a distributed collaborative system are based on asynchronous and unreliable communications. Trust is an essential and facilitating component in these interactions specially in such uncertain environments. Various attacks are possible due to large-scale nature and openness of these systems that affects the trust. Peers has not enough inform...

Abstract: Optimization of DG and capacitors is a nonlinear objective optimization problem with equal and unequal constraints, and the efficiency of meta-heuristic methods for solving optimization problems has been proven to any degree of complex it. As the population grows and then electricity consumption increases, the need for generation increases, which further reduces voltage, increases los...

متن کاملA Service-Oriented Approach for the Pervasive Learning Grid
This work proposes p-Learning grid, a service-oriented approach, based on a pervasive learning grid, for solving difficulties associated with the sharing of learning resources distributed on different e-Learning platforms. The p-Learning grid not only enables collaboration and effective reuse of learning objects but also supports learning anytime, anywhere. Since the WSDL of web services remain...
