The purpose of this study is to represent a generic model of digestion in the small intestine. In the first part of this work, a model based on ordinary differential...

With the rise of energetic demand and the growing scarcity of proved reserves of oil, the oil industry explores areas of extreme conditions and geologically complex...

This thesis carries out some studies concerning the mathematical modelling and the numerical approximation of problems involving homogenized metamaterials. In the...

Terrestrial plants and aquatic vegetation are submitted to a strong interaction with the external fluid flow. In order to overcome the flow-induced loads, plants...

Maintenance, repair and reinforcing of masonry walls with composite materials glued require the development of methods and techniques for evaluating the suitability...

Composite shock-absorbing devices can dissipate a large amount of energy, thanks to the combined action of delamination and fragmentation of the plies in compression....

The purpose of this work is to analyze and develop mathematical concepts and tools in application to performance assessment of an underground nuclear waste disposal....

This thesis aims at numerically simulating gas flows in porous matrices with micro-sized pores. We study the influence of hydrodynamic slip phenomena that appear when...

Les installations des industries hautes températures (i.e. sidérurgie, incinération...) sont soumises à des conditions d'exploitation sévères. Ces structures...
