Context-aware applications behave differently depending on the context in which they are running. Since context-specific behavior tends to crosscut base programs, it can advantageously be implemented as aspects. This leads ...

Strong similarities have been long observed between the Galois (Categories Galoisiennes) and the Tannaka (Categories Tannakiennes) theories of representation of groups. In this paper we construct an explicit (neutral) ...

Nowadays there are many on-line applications in which users’ feedback is used to compute a trust value for products, services and also other users. In those application domains, trust models are required and extensively ...

The emerging research on automatic identification of user’s contexts from the cross-domain environment in ubiquitous and pervasive computing systems has proved to be successful. Monitoring the diversified user’s contexts ...
