The originality of the project developed during this thesis was based on the synthesis and the study of photo-magnetic heterostructures in a temperature range...

In aeronautics field, the constraints are such as the mass of the filters can represent upto 50% of the total mass of the converter. During the last years, magnetic...

The research presented in this thesis concerns, firstly, an experimental study on the process of fracture in uniaxial compression of rock samples containing narrow,...

Due to safety rules running on fourth generation reactors’ core development,neutronics simulation tools have to be as accurate as never before. First part of this...

This PhD is dedicated to the development of an advanced numerical model for simulating interactions between free surface waves of arbitrary steepness and rigid bodies...

For fifteen years many studies have used MIMO systems to increase the Shannon capacity of the traditional SISO systems. To this end, a crucial problem is the design of...

As Operators strive today to optimize their networks, considerations of cost, availability, eco-sustainability, and quality of service are beginning to converge....

We find all the spherical functions on the space of infinite dimensional Hermitian matrices with reels, complexes or quaternions coefficients witch are invariantes by...

The main topic of the thesis is the transport in mesoscopic systems. In the first part of the work, we study thecase of a connection through an adiabatic potential on...

This study focuses on the processing of composite materials reinforced with short fibres or fibres bundles such as SMC or BMC. Firstly, an experimental work was...

With most of formal methods, an initial formal model can be refined in multiple steps, until the final refinement contains enough details for an implementation. Most...

The phenomenon of dewetting is characterized by the Vertical Bridgman growth of a crystal without contact with the crucible wall due to the existence of a liquid...

Topological features of an object are fundamental in image processing. In many applications,including medical imaging, it is important to maintain or control the...

Abstract In recent years a strong interest has been devoted to supercapacitor technology. However, while great attention has been paid to electrodes, electrolytes and...

In the setting of hyperbolic 3-manifolds, Thurston conjectured that every connected, orientable, complete hyperbolic 3-manifold of finite volume has a finite cover...

The safety criteria to be met for Generation IV sodium fast reactors (SFR) require reduced and mastered uncertainties on neutronic quantities of interest. Part of...

Modern portable vision systems include several types of image sensors such as colour, low-light or infrared sensor. Such system has to support heterogeneous image...

For more than 50 years, microelectronic industry is driven by a race to the miniaturisation of its central element, the MOS transistor, to improve the integration...

In nuclear plants, some accidental situations can result in air exposure of Pressurized Water Reactor (PWR) fuelassemblies: air ingress following a breach in the...

The demand of electronic components in all embedded and miniaturized applications encourages to developlow-cost components, in term of energy consumption and...
