On étudie l’application des algorithmes de décomposition matricielles tel que la Factorisation Matricielle Non-négative (FMN), aux représentations fréquentielles de signaux audio musicaux. Ces algorithmes, dirigés par une fonction d’erreur de reconstruction, apprennent un ensemble de fonctions de base et un…

Purpose – Information and communication technologies have became pervasive in people’s lives and in this changing world education cannot remain anchored in old-fashioned models which ignore the evolution through which society is going. This paper seeks to present the gamble…

This thesis proposes a methodology for the design of man-machine interfaces by combining top-down and bottom-up processes in vision. From a computational perspective, we propose that the scientific-cognitive question of combining top-down and bottom-up knowledge is similar to the engineering…

There are different approaches used by mathematics teacher educators to help pre-service primary teachers develop the useful skills and knowledge required to teach mathematics. One of these approaches is concerned to learning to notice relevant aspects in mathematics teaching. But…

Drak2 est un membre de la famille des protéines associées à la mort et c’est une sérine/thréonine kinase. Chez les souris mutantes nulles Drak2, les cellules T ne présentent aucune défectuosité apparente en apoptose induite par activation, après stimulation avec…

Nutrigenomics covers disparate fields of nutrition science and has been defined in many different ways. In fact, this emerging field of science has multiple facets, many of which do not generate the same ethical issues. In particular, different ethical issues…

The theory of satellite loss resulting from a giant impact on Uranus (Parisi and Brunini 1997, Planet. Space Sci. 45, 181–187) is revisited, in the light of the discovery of its five outer moons (Gladman et al. 1998, Nature 392,…

Most studies on Japanese supplier-automaker relationships have focused on the nature of
the dyadic inter-firm relationship and the performance of the assembler. We examine the
relationship between a Japanese supplier's "customer scope strategy" (i.e. number of
customers) and the supplier's…

AI requires Logic. But its Classical version shows too many insufficiencies. So, it is very necessary to introduce more sophisticated tools, as may be Fuzzy Logic, Modal Logic, Non-Monotonic Logic, and so on [2]. Among the things that AI needs…

Accelerated by the new internet technologies, the past two decades have been characterised by a globalisation of trade and communications, along with major shifts in the balance between manufacturing and knowledge driven economies. New organisational cultures have grown out of…
