Glioblastomas are malignant tumor of poor prognosis. Therapeutic failure might be supported by cancer stem cells (CSCs); characterization of these cells and biomarkers...

 This thesis is concerned with the flow field of a viscous fluid around a solid particle embedded in a parabolic shear flow, near a solid plane wall on which a slip...

The main objective of this work was to design, produce and characterize a new familyof artificial proteins and to introduce new tailored specific binding sites within...

In the present thesis we are interested in semantic description of humans in images. We propose to describe humans with the help of (i) semantic attributes e.g. male...

The mantle deformation processes that control the thinning and break-up of continental lithosphere remain poorly understood. Our knowledge is restricted to either...

Our study follows two main lines: first, a reflection on the understanding of the concept of truth by the medieval authors of the texts of our corpus, historians of...

This PhD thesis is devoted to a theoretical study of polymer and ’polymer like’ systems in strictly two dimensions. Polymer systems in reduced dimensions are of high...

The mechanical properties of hydrated cements need to be optimized according to the nature of cement products. Among the factors of optimization, the addition of...

Nowadays, many applications are using virtual worlds. Those virtual worlds are generally populated with autonomous virtual characters which bring those environments to...

Important amounts of reactive gases and particles are emitted over equatorial Africa by human activities and naturally by forests, lightning and soils. The different...

Extracted air from polar ices of Greenland and Antarctica constitute a real archive of the past atmospheres of our planet. The aim of this study was to understand the...

The thesis focuses on the phenomenology related to passive imaging in Millimeter/Terahertz domain, 0.1 to 1 THz. In this domain, dielectric materials such as clothing...

With the constant decrease of dimensions in microelectronic devices, new problemes are raised. One of them is the variation of the transistor gate length, also called...

In this work, we consider the problem of optimization of the training sequence length when a Maximum a posteriori (MAP) detector is used. We consider a transmission...

An increasing interest has been observed in Wirless Sensor Network that can be explained by wide range of WSN applications as well as by the challenges involving the...

Surface plasmons (SPs) are modes of the electromagnetic field confined at the interface between a metal and a dielectric. Due to their hybrid nature, the SPs can be...

This work is devoted to the experimental investigation of the high temperature kinetics and spectroscopy of astrophysical gases. A versatile and existing High Enthalpy...

We first expose in this memoir efficient matrix multiplication techniques. We set up new schedules that allow us to minimize the extra memory requirements during a...

Study of SiGe nanowires growth by chemical vapour deposition and characterization by atomic force microscopy.The use of semiconductor nanowires as building block for...

During the re-energization of the auxiliaries of a nuclear power plant, the more dangerous step is the re-energization of the power transformer, because of the...
