X-Ray Diffraction Contrast Tomography (DCT) is a recently developed, non-destructive synchrotron imaging technique which characterizes microstructure and grain...

The evolution of fuel injection strategies in automobile engines has brought about new problem sets in their design and optimization. Among these, is the deposition of...

The purpose of our works is the implementation of methodologies for the resolution of the agro-food industry scheduling problem. Three new approaches based on genetic...

In order to better understand and clarify the cardio-respiratory responses of humans to physical exercise at varying levels of gravity acceleration (ag) we have set up...

Concerns about bioterrorism, emerging pathogens and pandemic influenza resulted, this last ten years, in a surge of development of new public health surveillance...

In this thesis, we study the notions of determinism and confluence in the context of concurrent and sycnrhnous systems. The latter are variants of the pi-calculus and...

Our aim was to develop a way to synthesize diarylethers using copper catalyted ligands immobilized on silyl-organic inorganic materials prepared by sol-gel. The...

In mountainous areas, infrastructures, roads and railways are subject to various natural hazards due to the gravitational phenomena. Beyond the danger to users, the...

The aim of this work is the study of photogenerated charge transport in hybrid films composed of π-conjugated polymers and of semiconductor nanocrystals, designed for...

Heavy juridical, moral and customary constraints weighed on women at the end of the « long » 18th century in Great Britain. The impact of such constraints on feminine...

This thesis concerns the problem linked to the association of the main components of an electrical network.The inductive nature of the elements to be connected...

There are two problems with the observation of exoplanets: the contrast between the planet and the star and their very low separation. One technique solving these...

Le sujet de ce travail est l'étude du Paléogène marin de la zone alpine externe. Son objet : rechercher par l'analyse détaillée des unités lithostratigraphiques...

The control of the flight behaviour of a projectile partly depends on the knowledge of the coefficients associated with each aerodynamic loading. Different tools are...

Brillouin scattering is a fundamental nonlinear opto-acoustic interaction present in optical fibers with important implications in fields ranging from modern...

The Late Jurassic-Early Cretaceous allocthonous arc sequences of the Mexican Cordillera belong to the Guerrero terrane. They accreted to the North American craton...

The Oman ophiolite offers a unique opportunity to observe a piece of oceanic lithosphere formed at a paleo fast spreading ridge, obducted on the continent and...

The diatom Haslea ostrearia has long been considered as the only organism able to produce a blue pigment called marennine, known for greening oysters’ gills in...

In this work, ultraporous silica layers with very low refractive indices (1,1-1,2) and thicknesses about one micrometer are prepared and integrated to two systems of...

Nos deux terrains de Sicuani et d 'Ocongate se situent à cheval sur la Cordillère Orientale et la Vallée interandine du Vilcanota, au Sud -Est de Cuzco . La...
