Émulation de mémoire partagée en environnements distribués dynamiques

Most distributed systems are large-scale and dynamic. Communication has thus become a critical issue and the shared memory, which is a reliable paradigm of communication, allows distributed nodes to exchange information through read and write operations. In this article, I introduce the challenges related to emulating a shared memory in a dynamic message passing environment where nodes constant...

Mémoire Du Stage Transmission Multimédia En Direct Dans Le Réseau Pair-à-pair

With the growth of the computing power of personal computer and the proliferation of broadband access to the Internet, media streaming has widely diffused. The high bandwidth required by live streaming multimedia greatly limits the number of clients that can be served by a source using unicast. IP Multicast should be a good solution to this problem, but the fact that the current Internet does n...

Mise en oeuvre d'une mémoire environnementale adaptée aux besoins d'un observatoire du domaine côtier : MEnIr

Research workers are generally using many various pieces of information in their investigations, e.g. bibliography or experimental observation databases. Archiving, cataloguing, indexing and describing such information resources are the only means to ensure their durability and efficient reuse. In the following, we propose a way to design an information system that is backed up on both the "env...

Construction d''une mémoire de projet en ingénierie mécanique utilisant les technologies web

Current CAD systems only consider the geometric modelling of product. Then an efficient support can be provided by a consideration of the all product development process and all its handled data. An interested solution can be the use of corporate memory. Thus, the designers could benefit of a tool integrating knowledge issued by projects developed in the company. In practice, the development of...
