The first part of my thesis is the description of an algebraic model for synchronized time series. It's an extension of the classic relational model, to which we add a...

Various civil or military applications, such as spectroscopy in the atmospheric transparency windows (3 – 5 µm and 8 – 12 µm ranges), require the use of mid-infrared...

Dynamic assessment of structures under ambient loads is an important applied field of the structural mechanics and synamic system theory, which is the subject of many...

This thesis aims at evaluating the impacts of Radio-Frequency Identification (RFID) within a healthcare context.The first parts of this dissertation describe the...

Graphs decompositions of small width are usually used to solve efficiently problems which are difficult in general. In this thesis, we focus on some limits of these...

The next generation of fibre-optic internet infrastructure will involve long-haul transmission systems with wavelength-division-multiplexed (WDM) channels at 40 and...

During the last years, broadband services and Internet applications have boomed, causing saturation issues in the networks and leading to an increase in bandwidth...

The current demand of digital communications (mobile phones, email, e-commerce ...) requires the development of systems which can guarantee full confidentiality. The...

Numerous applications have, as their main behavior, to wait for information coming from a foreign environment, to prepare a result, and to execute actions on this...

From a sociological perspective, this PhD dissertation analyzes how the norms of Aids prevention have been transformed among gay men in France. The research rests on a...

Downstream changes of the geochronological signature in the Po drainage allow to assess the relative sediment contributions shed from the orogenic source areas, in...

The present study deals with word frequencies distributions and their relation to probabilistic Information Retrieval (IR) models. We examine the burstiness phenomenon...

KRN7000 anti-tumor activity is due to immune system stimulation. It acts on autoimmunes diseases, bacterial and parasitic infections. Hence is needed the development...

In order to autonomously navigate in an environment, a robot has to perceive its environment correctly. Rich perception information from the environment enables the...

Self-collimation allows to propagate a light beam without any lateral spreading and in the absence of any optical waveguide. This thesis deals with the design of...

In oil extraction industry, efficiency of water-oil separators for offshore production is crucial. The aim of this work is to develop numerical tools able to model...

The behaviour of the Earth's magnetic field, at the timescale of a polarity interval, can be represented with the help of "Giant Gaussian Process" statistical models...

This thesis deals with a specific class of musically improvised phenomenons : the one's that are produced by at least two musicians in simultaneous and open...

We are concerned in this thesis by the problem of Image Information Mining (IIM) for exploitation and understanding of high resolution Synthetic Aperture Radar (SAR)...

BiFeO3 material is the subject of number fundamental studies in multiferroic materials. This interest is mainly cause by the existence of two long range order at room...
