Niveaux du 10B excités dans la diffusion élastique 9Be + p à 2 Ep 5 MeV

2014 Absolute differential cross sections of the 9Be + p elastic scattering have been measured between 2 and 3.8 MeV proton laboratory energy. Excitation curves at five angles between 03B8cm = 65° and 160° and angular distributions at Ep = 2.31, 2.44, 2.56, 2.62 and 2.73 MeV for 03B8cm = 40° to 140° have been obtained. These results together with the previous measurements at Ep ~ 5 MeV have bee...

Modélisation multi-niveaux dans AA4MM

In this article, we propose to represent a multi-level phenomenon as a set of interacting models. This perspective makes the levels of representation and their relationships explicit. To deal with coherence, causality and coordination issues between models, we rely on AA4MM, a metamodel dedicated to such a representation. We illustrate our proposal and we show the interest of our approach on a ...

De la simulation de construction collective à la détection de régions dans des images à niveaux de gris : L'inspiration des araignées sociales

Collective phenomena in biology can be a source of inspiration to propose multiagents methods in problem solving. They allow the design of individual behavior that are simple and that produce collectively complex phenomena. This article presents the process we followed to transpose a simulation model to a problem solving one. The initial biological context is the web building in social spider s...

Communications multi-niveaux sécurisées dans une flotte de terminaux mobiles

Current mobile devices, and mobile phones in particular, are equipped with different wireless technologies that increase and diversify their communication capabilities. The combined and effective use of these technologies offers various opportunities in terms of services and applications. However, it requires detailed analysis in terms of security and choice of the communication mean to use acc...
