Signal coming from the ground and gathered by a sensor, undergoes lot of perturbations and processes to be transformed in an image. All those processes can be modeled...

The reliable and accurate segmentation of anatomical volumes (normal or pathological) from imaging systems remains an important goal in the medical information...

This work contributes to the concern about sustainable development and integrated coastal zone management, with the overall objective of improving methods for remote...

Emissions of carbon dioxide are growing with the massive utilization of hydrocarbons for the production of energy and chemicals, resulting in a threatening global...

Direct wafer bonding refers to a process by which two mirror-polished wafers are put into contact and held together at room temperature without any additional...

The present thesis gives an overview of carbide aggregates (interphase precipitation and carbide fiber) in vanadium-alloyed steels, covering the aspects of...

In information systems (IS) research, there is a solid consensus in acknowledging Henderson’s & Vankatraman’s (1993) concept and model of strategy alignment. It...

This thesis studies logics which express properties on programs. These logics were originally intended for the formal verification of programs with pointers. Overall,...

The nuclear reactors of the 4th generation must allow an optimized use of natural resources,while performing at a high safety level. The framework of this thesis is...

The expansion of access to primary éducation eight years ago has led to majority of children in Kenya notably the less priviledged like girls and those from poor or...

The present work deals with exchanges in energy and matter and especially heat budget at the ocean surface in the Northeast Subtropical Atlantic Ocean. The shortwave...

The functional oxides are performing materials showing interestant properties. The study of the local environment respect to the average struvture is essential for the...

Considering spent fuel management (storage, transport and reprocessing), the approach using « fresh fuel assump-tion » in criticality-safety studies results in a...

A current challenge in the field of quantum integrable systems is the exact and explicit computation of correlation functions. In simple models such as the XXZ spin...

The Valanginian stage witnesses a positive carbon isotope excursion (amplitude 1.5-2‰) in the sedimentary records, the so-called « Weissert Episode ». This event...

Precision metallic tubes are widely used for biomedical applications. The requirements of such tubes in term of surface quality, precise dimensions and mechanical...

Surface nanostructuring is an intriguing field of materials physics that has been largely ado-pted for both aesthetic and functional purposes. Nanostructures can be...

In this thesis, we will focus on the physical implementation of visual cryptography, which consists in sharing a secret message between several unmeaning images,...

An assembly of solid objects of typical size, a fraction of a millimeter is not sensitive to thermal agitation. Indeed, these elements are too massive to be moved by...
