Résumé

Depuis la découverte du feu, la combustion a pris une place très importante dans la vie de l’homme et elle est même la raison  derrière la révolution industrielle.
Lors de cette conférence, nous parlerons de la nature de la flamme, sa couleur et les processus physico-chimiques qui se produisent. Nous aborderons  le problème des produits issus de la  combustion, lesquels pouvant être nocif à l’être humain et à l’environnement. Ceci nous mènera à parler de la suie et les mécanismes de sa formation. La dernière partie sera réservée aux différentes méthodes utilisées pour éliminer la suie issue  de la combustion.

Résumé

Les services web constituent un des challenges qui ont attiré de nombreux chercheurs de la communauté des Systèmes d’Information distribués et de l’IA ces dernières décennies. La découverte sémantique de services est une des problématiques que j’aborderais dans cette présentation en couvrant aussi bien le matching direct que le matching indirect (composition de services web). Différentes modélisations de la composition de services web seront présentées pour prendre en considération une topologie de réseaux particulière (réseaux ad-hoc) ou l’utilisation de modèles de la théorie des graphes en ramenant ce problème à celui de la recherche d’un transversal dans un hypergraphe.
Une autre problématique que je présenterais est l’invocation de services web une fois sélectionnés par le matchmaker afin de les valider. Après un état de l’art sur cette problématique, un protocole dynamique de communication DynWES entre les services web basé sur les automates à états finis que nous avons développé sera présenté. Une extension aux automates à états finis complexes sera également discutée.

Résumé

It is widely recognized that CMOS transistor scaling, as a vector for the pursuit of performance levels predicted by Moore's Law and required by future applications, will not last through this decade. Alternatives must be found, at both architectural and device levels. In this context, the emergence of new switching devices based on nanotubes (CNFET) or nanowires (NWFET) offers the opportunity to provide novel logic building blocks, to explore new possibilities for digital design and consequently to reconsider the paradigms of computing architectures to achieve orders of magnitude improvements in conventional figures of merit. In this talk, I will look at the emergence of technologies capable of building large regular structures out of silicon nanowires or carbon nanotubes, and how logic functions can be mapped onto them, particularly in the context of reconfigurable applications. Some pointers to the future evolution of these technologies, enabling design techniques and associated architectures will be given, as well as the issues that must be solved before nanoscale computing fabrics become a viable alternative to CMOS.

Résumé

An overview of all-metal waveguide filters for satellite payloads is offered in this talk. Initially, an historical evolution of this filtering technology, including typical electrical and mechanical requirements, is outlined. Next, recent advancements in full-wave analysis methods and automated design procedures of these filters are reviewed. Then, a Computer-Aided Design (CAD) tool based on such techniques (i.e. FEST3D "Full-Wave Electromagnetic Software Tool for 3D Waveguide Components") is introduced, and its practical application to the analysis and design of several examples of satellite filters is presented. In particular, direct-coupled rectangular waveguide filters, E-plane waveguide technology, dual-mode filtering prototypes and evanescent mode waveguide filters are considered. Classical topologies, as well as more novel configurations for each filter class, are discussed.

Résumé

Nowadays, massive amounts of data that are often geographically distributed and owned by different organisations are being mined. As consequence, a large mount of knowledge is being produced. This causes the problem of efficient knowledge management and mining. The main aim is to develop DM infrastructures to fully exploit the benefit of the knowledge contained in these very large data repositories. To this end, we introduced "knowledge map" approach to represent easily and efficiently the knowledge mined in a large-scale platform such as Grid. This also facilitates the integration and coordination of local mining processes along with existing knowledge to increase the accuracy of the final models. In this paper, we discuss its advantages and its design issues.
