We are more and more dependent on our computing infrastructure, and yet its security is challenged every day. From a research viewpoint, a lot of progress in security...

Cette thèse est vouée principalement à l'étude des enveloppes circumstellaires des étoiles de la fin de la branche asymptotique des géantes rouges (AGB), ou dans la...

Two methods are used to estimate the seismic motion for a given site, considering site effect. In the first part of the thesis, the empirical method is used. The data...

Plasmodium falciparum is a protozoan parasite responsible for the most severe form of malaria. In recent years, cases of resistance to antimalarial drugs have become...

This work deals with sea-level rise as biological, sedimentological and archeological indicators upon rocky and sedimentary coasts of Provence. This thesis is...

This thesis in algorithmic number theory presents a new probabilistic algorithm for solving dimension 5 quadratic equations over Z or Q without using any...

The numerical models that are more and more used as virtual prototypes require information on the input data as the geometrical dimensions, the physical...

Density Functional Theory (DFT) combined with the Broken Symmetry (BS) method is today widely used in the field of molecular magnetism for the computation of exchange...

Study the urban fortresses of Burgundy means interesting in the relationships between, on the one hand, these buildings and their occupants and, on the other hand, the...

Ce travail est consacré à une étude numérique des effest produits sur les signaux sismiques par la structure géométrique des formations superficielles, dans une...

In irrigated perimeters, upward capillary fluxes from shallow water tables increase salinization hazards. When natural drainage is insufficient, artificial drainage...

This dissertation had two objectives. First, we wanted to adopt an original approach regarding our literature review, by analyzing the results of six sub-categories of...

The initial motivations of this work come from the camera calibration in computer vision. We are especially interested in using jointly time measures in the images and...

Block copolymers auto-organize on dense area of 5-50 nanometers nano-objects. By adjusting parameters like molecular weight, it is possible to auto-organize spheres,...

This work focuses on the understanding of the mechanisms involved in plasma etching processes used to design sub-20 nm poly-silicon gates for MOS transistors. The...

Electrospinning is a process to produce the fibers in nano scale by injecting the polymer solution through a metallic needle to a high voltage electrical field....
