The software control architectures are the decisional center of robots. Unfortunately, the robots and their architectures suffer from numerous flaws that disrupt and /...

The lake La Godivelle-d'en-Haut (French Massif Central) is a mountain lake which is characterized by low temperatures and a very low primary production. In this...

A key point for the Proton Exchange Membrane Fuel Cell (PEMFC) improvement and commercialization is the enhancement of mass specific electroactivity of platinum to...

Selenium was recognized as an important micronutrient for both humans and animals. Several studies showed that increased selenium in the diet might be beneficial...

In real time collaborative systems, replicated objects, shared by users, are subject to concurrency constraints. In order to satisfy these, various algorithms, have...

In order to optimize the use of microcantilever in the way of chemical sensing, microporous sensitive coatings have been tried to detect ethanol, toluene and humidity....

In this thesis, we design three new authentication mechanisms based on user identity. Therefore, we bring improvements in access control for different classes of...

On the last decades, progresses on the understanding of clustering seismicity in time, size and space have been driven by two parallel approaches. From the one hand...

In ubiquitous computing, user needs may opportunistically emerge along the variation of the context of use. Thus, there is a need for dynamically composing interactive...

This thesis is devoted to supply applications of Clifford algebras to multichannel image processing. Moreover, we introduce the use of vector bundles framework in...

This thesis consists of four chapters and an appendix. The first chapter is dedicated to the fundamental ideas of the theory of Ricci flow, which shows how our works...

Bedload transport remains poorly understood partly due to the polydispersity of particles and resulting segregation. Experiments were carried out at the particle scale...

We use a microscope combining atomic force microscopy (AFM) and scanning tunneling microscopy (STM) at very low temperature (~100 mK) to study mesoscopic nanocircuits....

Chloroplast NTT1 mediates external supply of ATP in the plastids, which is pre- requisite for the maintenance of plastid metabolism during limited or missing...

Despite its unique ability to discern details that a “classical” instrument cannot see, optical interferometry is still strongly handicapped by the atmosphere. It...

F508del, the most frequent mutation found in cystic fibrosis (CF) population, impacts CFTR (Cystic Fibrosis Transmembrane conductance Regulator) trafficking and causes...

Nosocomial infections with multidrug-resistant bacteria are increasing in ICU. They have major individual and collective consequences. Mortality in the ICU and...

The Early Bronze Age in Palestine (3500-2000 B.C.) appears to have been an important transition period during which populations from former Chalcolithic chiefdoms...

This PhD aims to study caves and subterranean karst infillings deposits from Charente (Touvre catchment) as a memory of past climate and environments. From the concept...
