We are interested to an optimization problem on graphs (the Vertex Cover) in a very specific context: the huge instances of data. We defined a treatment model based on...

Rescuers, within the framework of their missions, operate in hazardous condition and sometimes put their health at risk. To minimize this risk, new personal protective...

This thesis is part of a global research project aiming at improving the autonomy of wheelchair users along an original approach based on the study of wheelchair...

The exposure of polymers to their environments leads to modifications of the macromolecular chemical structure which provokes irreversible changes of their functionnal...

Insulated Gate devices are more and more often used in AC operated light dimmer. These devices allow to ensure EMC compliance of the systems through waveform shaping....

A major problem of our time concerns electrical energy. If the industry represents a large part of electricity consumption, the domestic sector is no exception. The...

We propose a conceptual framework for the component based information systems (IS) engineering. This framework is based on the concepts of hyperclass and IS...

The synthesis of titanium oxide nanoparticles by laser pyrolysis is studied in this work. This original gas phase technique is a versatile method which allows us to...

The current unified school system has especially inherited from both the former elitist secondary School, and the assumptions of the middle and dominant classes :...

Sub-meter resolution satellite images, capture very detailed information, as for example, shape of buildings, roads, etc. The main purpose of the thesis is to propose...

We study contact geometry, and focus on the study of periodic orbits of the Reeb vector field. It is a conjecture of Colin and Honda that for universally tight contact...

Electro-acoustic music is still hardly studied in the field of Music Information Retrieval. Most research on this type of music focuses on composition tools, pedagogy...

During this work, we were interested in the design of plasmonic particles for the control of the absorption and the emission of light. Our strategy was to synthesize...

We are interested in studying a heat transfer problem which modeling a welding process. The approach that we consider deals only with the solid part of the plate. It...

During the last decade we have witnessed an exponential growth of digital documents and multimedia resources, including a vast amount of video resources. Videos are...

The issue of the role of visual experience and imagery in the haptic perception of raised-line pictures by blind and sighted people is addressed by the present...

Lactic acid bacteria inhibit food spoilage bacteria by producing large amounts of lactic acid and growth-inhibiting peptides termed bacteriocins. Bacteriocins are...

This study present an analysis of the French direct transitive motion verbs. To speak of 'motion verbs' suggests that we are dealing with a homogeneous class bringing...

Interfaces between materials having opposite dielectric constants support electromagnetic waves confined close to these interfaces called surface waves. For metals and...

Lean premixed combustion is widely used to limit pollutant emissions and improve efficiency. However in this situation combustion instabilities and associated noise...
