The goal of the POBICOS project is a platform that facilitates the development and deployment of pervasive computing applications destined for networked, cooperating objects. POBICOS object communities are heterogeneous in terms of the sensing, actuating, and computing resources contributed by each object. Moreover, it is assumed that an object community is formed without any master plan; for example,...
The paper targets heterogeneous sensor-actuator networks, in which nodes differ as to resources (sensors and actuators) they are equipped with. Each node contributes its specific sensors and actuators to be used by applications. The key assumption of "opportunistic pervasive computing" is that the actual mix of nodes (and that of available resources) is not known in advance to the programmer...
The paper presents a programming model for a new pervasive computing middleware. The middleware, called ROVERS, targets an environment composed of tiny, resource-constrained, wirelessly communicating nodes embedded into everyday objects. The environment is heterogeneous in that each node is equipped with a unique set of sensors and actuators. The des establish an ad-hoc network and contribute their...
La prévalence de l'atopie et de ses manifestations a augmenté au cours des trente dernières années. La composante génétique de ces maladies représente certainement le facteur de risque le plus important, mais ne peut à elle seule expliquer cette progression rapide. Il existe d'importantes variations de la prévalence de l'atopie entre les Pays de l'Est et les Pays Occidentaux, entre les régions industrialisées...
