We present various results of the last twenty years converging towards a homotopical theory of computation. This new theory is based on two crucial notions : polygraphs (introduce...
Cellular automata are a simple model of parallel computation. Many people wonder about the computing power of such a model. Following an idea of S. Wolfram [16], M. Cook [3] has pr...
Single sign-on is critical for the usability of distributed systems. While there are several authentication mechanisms which support single sign-on (e.g. Kerberos and X.509), it m...
We introduce a system that adds a foveal inset to large-scale projection displays. The effective resolution of the foveal inset projection is higher than the original display reso...

DIET (Distributed Interactive Engineering Toolbox) is a toolbox for the construction of Network Enabled Server (NES) systems. For most NES systems, as for most grid middleware sys...
