—In this work, we propose a framework for automatic dependency evaluation that can notify the changes of the elderly dependency, hence providing persons with required services in time. In order to validate our approach, we target the French dependent population. Especially, we focus our proposal on the AGGIR dependency model used in the French medical(More)
Previously, we developed a method and a distributed platform for the re-engineering of applications by adding cooperation. The goal was to supply a way of communication based on the exchange of events, messages and shared data. Now, we propose to adapt this approach (method and platform) to distributed multimedia applications. These applications present the(More)
Recently, the increasing use of mobile technologies leads to face with new challenges in order to satisfy users. New systems deal with three main characteristics: context changes, mobility and limited resources of such devices. In this article we try to address such requirements using QoS-driven dynamic adaptations of application deployment. We are(More)
Actual applications (mostly component based) requirements cannot be expressed without a ubiquitous and mobile part for end-users as well as for M2M applications (Machine to Machine). Such an evolution implies context management in order to evaluate the consequences of the mobility and corresponding mechanisms to adapt or to be adapted to the new(More)
— 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. Information Sytems must then guarantee users a quality of service ensuring data accessibility whatever the hardware and network conditions may be. They must also guarantee information(More)
—Multimedia contents are accessible on a wide variety of devices, such as laptops, tablets and smartphones. The hetero-geneity of such devices requires adaptation of these contents. Since the last decade, a fair amount of research has been conducted in order to develop adaptation frameworks. Most of them are exploiting profiles in order to guide adaptation(More)
This paper presents a software platform (called Kalimucho) for mobile and embedded hardware. The architecture of such application is based on two component models: Osagaia for software containers and Korrontea for connector containers. Kalimucho uses service factory permitting the creation of instances of software components. This factory allows making the(More)
This paper describes the methods used to acquire sea-level data for validation of MERIS water products in Belgian coastal waters and comparison of such measurements with MERIS level 2 data as available in November 2002. Results are presented for two Reduced Resolution level 2 images for which sea-level match-up data exists. One image was acquired during(More)
