This thesis is part of a project named TEROPP (for Technologies for TERminals in OPPortunistic radio applications) sponsored by the ANR (the french National Research...

In this memory, we introduce a vectorial design of feedback with carry registers introduced by Goresky and Klapper denominated VFCSR. Through the ring of Witt vectors,...

FeS clusters are widely used protein cofactors, found both in bacteria and eukaryotes. They play key roles such as electron transfer, substrate binding and activation,...

In the pattern mining field, there exist a large number of algorithms that can solve a large variety of distinct but similar pattern mining problems. This variety...

The work presented in this paper is in the field of Technology for Human Learning (TEL), specifically that of engineering in the context of TEL-type approach "Learning...

The effect of the soil organic status (SOS) on the dynamics and impact of a copper contamination was investigated in a coupled field and mesocosm study with a loamy...

This thesis presents a study of electronic transport in exfoliated graphene at low temperature. A first set of experiment at 4K on samples connected by titanium/gold...

The pathogenesis of Pseudomonas aeruginosa (P.a) implies multiple virulence factors among which the type III secretion system (T3SS). This multiprotein complex is...

The goal of this thesis is to develop better practical methods for detecting common object classes in real world images. We present a family of object detectors that...

The thesis investigated the development of children’s global/local processing hierarchical patterns introduced by Navon (1977). The objectives were to understand more...

Ubiquitous systems imagined by Mark Weiser are emerging thanks to the development of embedded systems and plug-n-play protocols like the Universal Plug aNd Play...

The first part of the thesis reports on the characterisation of MICROMEGAS prototypes in beam and laboratory tests. Detection efficiency, response multiplicity and...

Colloids -- e.g. nanoparticles in solution -- are objects that exhibit original optical properties. Their use as building block for fabrication of subwavelength...

This PhD thesis is devoted to conception of a miniaturized system of biochip type able to realize a controlled capture and release of different populations of the...

Organochlorines (OCs) -molecules used in industrial processes and in agricultural applications which are prohibited from use nowadays- are classified as very...

Information on food webs is central to understand ecosystem functioning. It also provides information of ecosystem stability by evaluating the resource availability...

Time-dependent density-functional theory (TDDFT) is a density-functional method for calculating excited states. TDDFT is formally exact, though in practice one has to...

Since 1997, influenza A viruses has given rise to great sanitary andeconomic interest after the emergence of a highly pathogenic subtype ofavian influenza virus H5N1....

The influence of increase in land pressure on agricultural production and the environment is disputed. On one hand the pessimists, mainly represented by MALTHUS...

Edge states are one-dimensional transport channels, emerging in quantum wells in the integer Quantum Hall regime, with remarkable properties of chirality and quantum...
