Statistical unsupervised restoration of signal can be applied in many fields such as economy, health, signal processing, meteorology, finance, biology, reliability,...

Remote-sensing techniques are widely implemented today for the exploration of planetary surfaces, called regoliths, such as the Moon's, Mercury's, Mars' or asteroids'....

This thesis focuses on the heritage process of mountains in the context of the implementation of the policy "Grand site" in the Canigou (Eastern Pyrenees). We analyse...

This thesis consists of five articles mainly devoted to problems in dynamical systems and ergodic theory. We consider non-uniformly hyperbolic two dimensional systems...

Prediction and assessment of the fate of xenobiotics in soil requires the participation of many different disciplines: microbiology, hydrology, soil science, process...

Ce mémoire est consacré à l'analyse des effets du confinement de l'air et du caractère multidimensionnel de l'écoulement lors des essais de caractérisation...

This work focuses on the navigation of a mobile robot equipped with a camera in a cluttered environment. To perform such a task, we propose to use the image based...

The Mediterranean region shows a marked vulnerability to wildfires that are a rising threat to natural ecosystems and population. A coupled modelling approach allows...

The complicated underwater environment and the poor underwater vision make super-mini underwater cable robot hardly to be controlled. Traditionally, the manual control...

Incorporating reversible bonds in polymer materials is an attractive method for obtaining crosslinked networks, that can still be reshaped or recycled after use. In...

Since MOS Field Effect Transistor invention in the 60's, the exploitation of this elementary piece of technology allowed an exponential evolution in the...

L'étude sur le terrain de l'infiltration des eaux de pluie, de leur cheminement à travers le sol, ou, à l'inverse, de l'assèchement du sol par évaporation constitue un...

Alors que le comportement hydraulique des sols saturée (réseaux de puits, de drains, etc ...) est relativement bien connu, grâce à l'avancement de l'hydraulique des...

Metatheses are very useful synthetic tool for the formation of carbon-carbon bonds and their popularityis due to the facile access of the required catalyst for those...

The microelectronic industry is still ruled up to now by the law of miniaturization or scaling. In particular, in CMOS (complementary metal-oxide semiconductor)...

The growing development and use of pervasive systems, equipped with increasingly sophisticated functionalities and communication means, offer fantastic potentialities...

In this thesis, we are interested in adapting algorithms to parallel architectures. Current high performance platforms have several levels of parallelism and require a...

The lateral emergency transshipment in distribution systems consists in organizing inventory transferts between retailers to face shortage situations. Its...

In this thesis, we first present a contribution to overcome this problem of robustness for the recognition of object instances, then we straightly extend this...

La Hamada du Guir est un vaste entablement, allongé du Nord au Sud sur 250 km entre les vallées du Ziz et du Guir, au Sud-Est du Maroc. La formation sédimentaire qui...
