Pervasive computing applications allow users to access information from anywhere while traveling and using variety of devices. Heterogeneity and limitation of resources involved in this application demand adaptation of content according to the current context (device, user, network etc.). The dynamic nature of adaptation mechanisms together with emerging(More)
Computation and data grids have encountered a large success among the scientific computing community in the past few years. The medical imaging community is increasingly aware of the potential benefit of these technologies in facing today medical image analysis challenges. In this paper, we report on a first experiment in deploying a medical application on(More)
The behavior of pervasive applications should depend not only on their internal state and user interactions but also on the context sensed during their execution. In this paper, we propose an ontology-based generic context management (GCoM) model. The GCoM model facilitates context reasoning by providing structure for contexts, rules and their semantics.(More)
In this paper we study the use of networks of PCs to handle the parallel execution of relational database queries. This approach is based on a parallel extension, called parallel relational query evaluator, working in a coupled mode with a sequential DBMS. We present a detailed architecture of the parallel query evaluator and introduce Enkidu, the eÆcient(More)
The behavior of pervasive applications depend not only on their internal state and user interactions but also on contexts sensed during their execution. In this work, we present a collaborative context-aware service platform based on hybrid context management model (enhanced CoCA). It performs reasoning and decisions based on context data, context(More)
Pervasive systems are created by introducing wireless communication into distributed multimedia systems. These systems facilitate mobile data access to applications such as health care, tourism and emergency. However new challenges have emerged that has not been adequately addressed in traditional distributed multimedia systems. In pervasive systems, data(More)
The introduction of pervasive computing environments in everyday life will not just be a big step for users, but also for application designers. The well defined interaction interfaces will make place for other, more intuitive ways of interaction. It is the challenge for a pervasive system middleware to capture and model the user intention in a smart way(More)
