In this thesis three themes related to wireless sensor networks (WSNs) are covered. The first one concerns the power loss in a node signal due to voltage droop in the...

This work aims to study the effects of a few pesticides and one adjuvant on marine organisms, representatives of four trophic levels : micro-algae, echinoderm,...

La coupe stratigraphique du Monte Boulliagna n'est pas tout a fait une coupe triasique Briançonnais de référence . Trias briançonnais, Trias de Vanoise ?

Cette thèse présente une étude minéralogique, géochimique et d'inclusions fluides des gisements de la province métallogénique de Belledonne. Cette province fait partie...

A study of high-pressure metapelites from the Western Alps reveals a wide range of metamorphic grades, ranging from a Fe-Mg-carpholite zone, through an intermediate...

Water is an important constituent of the atmosphere of red supergiant stars (RSG), which influence remains however poorly understood. The water spectrum of these stars...

As well as the large companies, also the small and medium-sized enterprises desire to take advantage of modern management methods to improve their process, their...

This work aims to develop, in thin film form, integrated structure based on tunable materials such as ferroelectrics and relaxor dielectrics for microwave devices....

The main features of the Eastern (EP) and Central (CP) Pacific El Niño Southern Oscillation (ENSO) events are analyzed using 1950-2010 observed and modeled data. Using...

The Eastern English Channel is a macrotidal epicontinental sea, subject to an increasing demand for marine aggregate extraction since several decades. Effects on the...

Over the last twenty years, research in ensemble predictions at a seasonal timescale using general circulation models has undergone a considerable development due to...

The increasing development of Wireless Camera Sensor Networks today allows a wide variety of applications with different objectives and constraints. However, the...

This thesis compiles two distinct studies that both document the control of microstructures on rock seismic properties. The first part deals with the development of...

The goal of this study is the analysis of the stability and receptivity properties of the three-dimensional flow past the leading edge of a swept wing. The project is...
