remarquable par son interdisciplinarité qui fait référence tant à <strong>la</strong><br />

This thesis puts the topic of chaos communications on a unified<br />

theoretical basis by i<strong>de</strong>ntifying that statistical estimation of<br />

transmitted symbols is the key receiver concept, and realising that<br />

the use of statistical likelihoods based on the supposed mo<strong>de</strong>ls is<br />

the optimally correct approach. This highly original research work<br />

brings perspective, organisation and or<strong>de</strong>r to the question and will<br />

ease the way for others to comprehend the important issues of this<br />

new domain.<br />

The author <strong>de</strong>scribes an innovative method for investigating<br />

unsaturated soils contaminated with organic compounds. Because it<br />

is simple, cheap and rapid, this technique presents an excellent<br />

potential of becoming a standard method. This work contributes thus<br />

significantly to a very new field of tracer techniques applied to soil<br />

gas.<br />

At the interface between nonlinear dynamics and machine learning,<br />

<strong>de</strong> Feo’s thesis proposes the use of chaos theory for temporal<br />

pattern recognition. This is a new i<strong>de</strong>a, potentially opening the way<br />

to the <strong>de</strong>velopment of powerful methods for the un<strong>de</strong>rstanding of<br />

interesting cognitive processes. Drawing from several disciplines,<br />

the candidate accomplishes a tour <strong>de</strong> force intaking a truly original<br />

i<strong>de</strong>a and <strong>de</strong>veloping it to a level of un<strong>de</strong>rstanding that makes it<br />

applicable in several real-world problems in information technology.<br />

La substitution <strong>de</strong>s combustibles fossiles par l'hydrogène d'origine<br />

renouve<strong>la</strong>ble est l'une <strong>de</strong>s solutions à long terme pour diminuer <strong>la</strong><br />

charge atmosphérique en CO2. La famille <strong>de</strong>s piles à combustible à<br />

basse température représente en effet une alternative prometteuse<br />

au moteur à combustion interne. Ces piles requièrent cependant<br />

une alimentation en hydrogène <strong>de</strong> haute pureté.<br />

Dans sa thèse <strong>de</strong> doctorat, Bastien Monnerat conjugue les avantages d'une dynamique <strong>de</strong>s flui<strong>de</strong>s optimale et <strong>de</strong> <strong>la</strong> haute conductibilité thermique <strong>de</strong>s lits catalytiques<br />

fixes pour produire <strong>de</strong> l'hydrogène à partir <strong>de</strong> méthane (gaz naturel), suffisamment pur pour être servi directement comme combustible <strong>de</strong> ces piles. Il contribue ainsi<br />

gran<strong>de</strong>ment à <strong>la</strong> production d'une énergie non-polluante pour le secteur <strong>de</strong>s transports routiers, toujours en croissance.<br />
