This paper presents the modeling strategy developed for the design of a planar solid oxide fuel cell repeat element. Design goal are to reach good performance (power density) and reliability (ie. limit risk of failure and degradation). This challenging problem, involving multiple physical phenomena, different scales (from the pores of the catalyst to the interaction of the fuel cell with the system), is addressed with a multi-scale modeling approach. Handling the complexity of the problem (including kinetic

This paper presents the genesis of the Expo.02 robot. RoboX the tour guide robot has been built from the scratch for this project based on the experience of the Autonomous Systems Lab. The production of 11 of those machines has been guaranteed by a spin-off of the lab: BlueBotics SA. The goal was to maximize the autonomy and interactivity of the mobile platform while ensuring high robustness, reliability and performance. The result is an interactive moving machine which can operate in human environments and

« Environmental Geomechanics » is a relatively new discipline at the interface between built and natural environment. It is devoted to the understanding of the mechanical behavior of geomaterials (mainly soil and rock but also concrete and others) under various environmental conditions. The new theories and models developed in this context will find applications in a large field of engineering (waste disposal, underground structures, agriculture, natural disasters, energy production, depollution, etc.). Com

This paper is a state of the art review of the use of formal methods in the design of cryptographic protocols.

A design methodology allowing engineers to consider simultaneously and from the earliest phases of design some of the key factors of sustainable development (pollution, life cycle data) has been developed and successfully demonstrated on two examples of integrated energy systems. The principal idea is to take diverse factors related to thermodynamics, economics and the environment and integrate them in a way that the most optimal syntheses and designs (and operation) can be found. The solution space resulti

In this paper, we propose an architecture for hybrid services, i.e., services that span many network technologies, especially the PSTN and the Internet. These services will play an important role in the future, because they leverage on the existing infrastructures, rather than requiring brand-new and sophisticated mechanisms to be deployed. We explore a few issues related to hybrid services and propose a platform, as well as a set of components, to facilitate their creation and deployment. The existing infr

Mobile robots are of high interest for unmaned planetary exploration. The very successful Pathfinder mission to Mars has impressively demonstrated the potential of mobile platforms for planetary exploration [1]. The European Space Agency (ESA) also started to develop concepts for micro-rovers for Mars missions. Within an interdisciplinary group of companies specialized in space applications and research labs new designs of micro-rovers have been investigated. Two concepts, a simple and robust one and an inn
