In an autonomous navigation context, a precise localisation of the vehicule is important to ensure a reliable navigation. Low cost sensors such as GPS systems are...

The monitoring of the suspended sediment concentration (SSC) in rivers is essential for the management and control of the quality of waterways. Moreover, the knowledge...

Many mammals can behave according to different navigation behaviors, defined as " strategies " which, although not systematically requiring conscious processes, depend...

The presented work aims mainly at simplifying the study of energy transfers involved in converters. A preliminary mathematic* study leads to introduce a new element in...

Power systems are undergoing profound changes due to the deregulation of the power industry. One of the consequences of this deregulation is the emergence of dispersed...

The objective of this thesis is to contribute as well on the theoretical level as empirical to the research on the links between the macro-economic policies and the...

My work consists in developing some high order numerical schemes in time and space for the modeling of the wave propagation. We have proposed to first discretize the...

A copy number variation of genes from human chromosome 21 (HSA21) leads to morphological and physiological anomalies of a great number of organs among patients....

The Take of Alexandria is a rhymed narrative which recounts the exploits of Peter I of Lusignan, kingof Cyprus and Jerusalem, new Godefrey of Bouillon ; it was written...

The work of modeling present in this thesis relates to the study of the hydro-poro-mechanics behavior of geomaterials with the numerical approach of up-scaling. This...

Cell transplantation has emerged as a promising therapy for some kind of severe heart failure refractory to conventional treatment. We have attempted in this work to...
