In this thesis we address the problem of distributing large contents in the Internet. We focus on two interesting and very common services, video on demand (VoD) and file replication. We first investigate how to provide an efficient VoD service to a large number of clients in a dedicated overlay network (e.g. Akamai [5]). Our contribution here is a new video distribution architecture that is hi...

A component is a self contained entity that interacts with its environment through well-definedinterfaces. The component library Fractive provides high level primitives and semantics for program-ming Java applications with distributed, asynchronous and hierarchical components. It also providesa separation between functional and non-functional aspects, the latter allows the execution...

In this thesis we are interested in a particular class of problems which frequently appear in robotics (and many other areas as chemistry, molecular biology, Computer-Aided Design (CAD), and aeronautics). They are systems of distance equations with uncertainties. Uncertain values mean values which are not exactly determined but are bounded by well-known limits. These values are represented as i...

This thesis concentrates on real-time acoustic simulations for virtual reality applications or video games. Such applications require huge computing times, increasing with the complexity of the scene and involving difficulties for interactive rendering. In particular, the real-time simulation of a complex sound scene remains difficult due to the independent processing of each sound source. More...
