Development of ubiquitous applications is inherently complex. Adaptation system is a
solution for ubiquitous computing. It enhances the efficiency of application by the adaptation …

Modern mobile devices spreading introduce a new way of using and designing software
applications. These pervasive systems are now part of our lives. More and more connected …

One of the current challenges of Information Systems is to ensure semi-structured data
transmission, such as multimedia data, in a distributed and pervasive environment …

We extend soft nearest neighbor classification to fuzzy classification with adaptive class
labels. The adaptation follows a gradient descent on a cost function. Further, it is applicable …

L'un des défis actuels des systèmes d'information est d'assurer la transmission de données
semi-structurées telles les données multimédia dans un environnement distribué et …

Dans cette thèse, nous avons choisi d'aborder l'adaptation dynamique au contexte comme
un outil de gestion de la qualité de service. Nous présentons une plate-forme pour la …

Integrating physical and information space into applications increases application's
complexity and development difficulty. In Ubiquitous environment, context collection …

Résumé Le développement d'applications ubiquitaires est particulièrement complexe. Au-
delà de l'aspect dynamique de telles applications, l'évolution de l'informatique vers la …

Resource-constrained embedded and mobile devices are becoming increasingly common.
Since few years, some mobile and ubiquitous devices such as wireless sensor, able to be …

Sistemas multimídia devem incorporar conceitos de middleware de forma a abstrair
