Our claim is that semantic metadata are required to allow a real reusing and assembling of learning objects. Our system is based on three models used to describe the domain, users and learning objects. In order to automatically process these models and have basic reasoning capabilities, we have defined mappings to RDF. A prototype is being developed using(More)
Our approach proposes the creation and management of adaptive learning systems by combining component technology, semantic metadata, and adaptation rules. A component model allows interaction among components that share consistent assumptions about what each provides and each requires of the other. It allows indexing, using, reusing, and coupling of(More)
BACKGROUND Friedreich's ataxia usually occurs before the age of 25. Rare variants have been described, such as late-onset Friedreich's ataxia and very-late-onset Friedreich's ataxia, occurring after 25 and 40 years, respectively. We describe the clinical, functional, and molecular findings from a large series of late-onset Friedreich's ataxia and(More)
Nowadays, complex systems are distributed over several levels of Information and Communications Technology (ICT) infrastructures. They may involve very small devices such as sensors and RFID, but also powerful systems such as Cloud computers and knowledge bases, as well as intermediate devices such as smartphones and personal computers. These systems are(More)
With the Internet of Things (IoT) paradigm, ambient systems move from locally distributed systems to Internet distributed systems. These systems become huge in term of number of devices and imply high heterogeneity (e.g., Of devices, of networks). They are continuously evolving with appearing and disappearing devices at runtime. The inner complexity of(More)
Technical advances in machine and system virtualization are creating opportunities for remote learning to provide significantly better support for active education approaches. Students now, in general, have personal computers that are powerful enough to support virtualization of operating systems and networks. As a consequence , it is now possible to(More)
RÉSUMÉ. Nous proposons de simuler les Systèmes d'Information des Smart Grids afin de vali-der/critiquer les choix de modélisation des experts métier. Nous proposons une approche par points de vue selon deux aspects information et dynamique tout en ajoutant un point de vue inté-gration pour le maintien de cohérence. Nous mettons à contribution les techniques(More)
