Mécanique Des Couches Minces Fonctionnelles : Instabilité Et Adhésion

We have studied thin film instabilities and in particular buckling driver delami-nation of thin films on rigid substrates. In the first part we studied residual stressin molybdenum thin films deposited by magnetron sputtering. With these resultswe can deposit a film with high compressive stresses for delamination. In the secondpart, compressive stressed layers are used to induce...

Darwin et la socialit\'e : entre anthropomorphisme et gradualisme

We propose, in this article, an analysis of the Darwin’s approach to sociality. Sociality is perfectly integrated into the selective model, and is caused by the same process as struggle for existence. Thus, the selective process does not prohibit demonstrating cooperation, but on the contrary, explains it. We will see that the unification of sociality, in a more adequate representation to mamma...

Descripteurs directionnels d’enlacement et d’entrelacement entre objets

The analysis of spatial relationships between objects in images plays a crucial role in various application domains related to pattern recognition and computer vision. In this article, we adress the issue of describing complex spatial configurations, where objects can be imbricated in each other. We formalize this notion with two new spatial relations called the enlacement and interlacement. We...
