Capital humain et compétences de base des adultes : production et valorisation
Basic skills are important in current policies because of high costs generated by illiteracy and supported by the society. The aim of the present thesis is to bring a... -
Quantitative X-ray phase imaging with a lateral shearing interferometer. Appl...
Since Röntgen discovered X-rays, X-ray imaging systems are based on absorption contrast. This technique is inefficient for weakly absorbing objects. As a result, X-ray... -
Extension of the master-curve approach for lifetimes predictions of complex c...
The main objective of this thesis was to investigate how it is possible to extend the master curveapproach to complex components, in order to calculate annealing... -
Une architecture semi-supervisée et adaptative pour le filtrage d'alarmes dan...
We study the current limitations of systems processing alarms generated by network intrusion detection systems (NIDS ) and propose a new automatic approach that... -
Experimental and numerical investigation of thermomechanical couplings and en...
Strain localization and damage criteria of materials and structures are commonly based on a dissipative framework and this work investigates the thermomechanical... -
Multi-level approaches for optimal system design in railway applications
Within a globalized market context, the classical trial-and-error design process is no longer capable of answering to the ever-growing demands in terms of short... -
Major Histocompatibility Complex and functional genomics in spondyloarthritis
Spondyloarthritis (SpA) is a frequent chronic inflammatory rheumatic disorder, with a prevalence of 0.3% in France. Pathological mechanisms leading to SpA remain... -
Applications of bipolar electrochemistry : from materials science to biologic...
Bipolar electrochemistry deals with the exposure of an isolated conducting substrate that has no direct connection with a power supply except via an electric field.... -
Formal Proofs for Global Optimization -- Templates and Sums of Squares
The aim of this work is to certify lower bounds for real-valued multivariate functions, defined by semialgebraic or transcendental expressions and to prove their... -
Flat versus normal subduction zones : a comparison based on 3-D regional trav...
Beneath central Chile and western Argentina, the oceanic Nazca slab drastically changes geometry from horizontal to dipping at an angle of 30°, and correlates with the... -
Robustness and stability of nonlinear systems : a homogeneous point of view
The purpose of this work is the study of stability and robustness properties of nonlinear systems using homogeneity-based methods. Firstly, we recall the usual context... -
Deformations of twisted harmonic maps
We study the deformations of twisted harmonic maps f with respect to a representation. After constructing a continuous "universal" twisted harmonic map, we give a... -
Contribution to study of lifetime duration of power assemblies in high temper...
In avionic applications, semiconductor devices can be placed on the engine with an ambient temperature about 200°C and thermal cycling from -55°C to 200°C in the worst... -
Nanostructured hybrid solar cells based on PECVD grown SiNWs and organic semi...
Solar cells are an exciting alternative energy technology due to the infinite energy source, the Sun. Many types of solar cells based on inorganic or organic materials... -
Study of the ageing of digital optical discs : research into correlations bet...
Optical discs are often used by many private or public organizations to archive essential data. For a long time these media were supposed to be reliable. However, a... -
Emission, scattering and localization of light in complex structures: From na...
Using nanostructures to confine light allows to increase the interaction between an emitter and electromagnetic radiation. In this thesis, we use a classical formalism... -
Optimal and multi-physic design of inductors-transformer associated to railwa...
Nowadays, power converters in railway domain are more and more compact and powerful. This progress is due to the use of fast efficient components, working at high... -
Stratégie de calcul et utilisation de séries de Fourier pour les tubes compos...
During the manufacturing of composite pipes (carbon/epoxy), some defects appear (delamination, cracking). The problem is then to decide whether a pipe is usable or... -
Syntheses of fluorinated nanocarbons for electrochemical energy storage
For primary lithium batteries, the lithium anode can be coupled mainly four cathode materials (MnO2, SO2, SOCl2 and fluorinated carbons CFx). Li/CFx batteries have... -
Study of the Northern Current dynamics in the Toulon region, using modelling,...
The main objective of this work is to improve our knowledge of the Northern Mediterrranean Current (NC) variability and its interactions with coastal dynamics, using...
