Our problematic concerns the links between logic and topoï, semantics and topoï and finally between logic and semantics. The work therefore consists in highlighting the durability of the notion of topos, its evolution and its integration in logic, in semantics and even in computer science. From then on, topoi, logic and semantics are the three facets of this problematic. The purpose of this thesis is to present the history of topoi, to identify their linguistic properties. It also shows that this notion is present in all linguistic approaches and that semantics is the unifying axis of all linguistic research.It is not our intention to give a new definition, but we have tried to su…
Avatars du conte au XXe et XXIe siècle
2013
National audience; Dans Les Contes du chat perché, Marcel Aymé se livre à un jeu de reprise et, en même temps, de réécriture du conte traditionnel. S’il produit un effet de conte, en reprenant un traitement de la temporalité, un type de structure empruntés à la tradition, il crée une forme nouvelle affranchie de tout didactisme, beaucoup plus littéraire dans ses effets, notamment par le traitement du personnage. Cependant, même si l’auteur met en scène un imaginaire qui lui est propre, le traitement du merveilleux reste fondamentalement celui du conte.

Contribution to the study of interaction between residual stress and oxygen diffusion in a deformable and reactive solid
2011
The aim of this PhD work is to highlight the interactions between the mechanical stress and the chemical composition within diffusion of matter process for a reactive solid. The chronological evolution of our work goes from a parametric numerical study to an experimental study and reveals the role of mechanical stresses on the oxygen diffusion process.Different origins of mechanical stress were first numerically analysed from the point of view of their impacts on the process of oxygen diffusion into a metal (Zr) or a ceramic (UO2) subjected to an oxidizing environment. This approach allowed us: to identify a surface treatment (shot-peening) able to generate a residual specific stress field,…
Characterisation of mechanical behavior of a sub surface drilled polymer, under hertzian contact load
2013
This research concerns the understanding of the sub-surface behaviour of a component presenting controlled heterogeneities and subjected to a Hertzian type load. The purpose is to qualify the stress field in the subsurface. Practically, defects of cylindrical shape are located where the stress field is maximal in sub surface. The contact is sized to be able to observe, by photoelasticity, the stress field and to develop a numerical model to simulate the behaviour (static and dynamic) of the friction area. It is highlighted that the presence of a hole on the z axis of symmetry (x = 0) is the dominating factor. The characteristics which allow decreasing the shearing stress on the symmetry axi…

Many practical tasks in industry, such as automatic inspection or robot vision, often require scanning of three-dimensional shapes with non-contact techniques. However, transparent objects, such as those made of glass, still pose difficulties for classical scanning techniques. The reconstruction of surface geometry for transparent objects is complicated by the fact that light is transmitted through, refracted and in some cases reflected by the surface. Current approaches can only deal relatively well with sub-classes of objects. The algorithms are still very specific and not generally applicable. Furthermore, many techniques require considerable acquisition effort and careful calibration. T…
Manufacturing and characterization of Al matrix composites with nano reinforcements via cold spraying
2019
This study aims at developing new routes for manufacturing Al matrix composites (AMCs) strengthened with nano reinforcements by solid-state cold spraying (CS) process. Three different AMCs including CNTs/Al, TiB2/AlSi10Mg and TiB2/7075Al were successfully fabricated by CS of the composite powders prepared using different approaches. The microstructure evolution of as-sprayed composite samples was investigated by means of different characterization methods like X-ray diffraction (XRD), scanning (SEM) and transmission electron microscopy (TEM) and electron backscatter diffraction (SEM/EBSD). The adhesion strength, tribological behaviour, corrosion properties as well as the mechanical performa…
Fonctionnalisation de surfaces métalliques par des couches minces d'oxynitrures de titane obtenues par irradiation laser sous atmosphère contrôlée et…
2013
The technological advances in areas such as automotive and aerospace industries require materials capable of withstanding demanding conditions. Surface treatments are effective tools to improve the surface properties of materials while preserving their bulk properties. Besides many conventional processes, laser treatments are efficient methods for hardening and increasing the durability of materials. This work is focused on the growth of titanium oxynitride surface layers by laser irradiation of pure titanium plates with nanosecond pulsed sources. The influence of the laser treatment conditions on the composition and the structure of these surface layers was studied. In particular, for lase…
Souffrance, jugement moral et « société addictogène » : les registres de sens du traitement de la dépendance
2019
Cet article explore la teneur de l’évaluation morale dans les modes de traitement du « trouble addictologique » en s’intéressant aux trajectoires des personnes en prise avec des produits psychoactifs inscrites dans une démarche d’arrêt ou de diminution des consommations d’alcool ou des drogues illicites. En suivant ces trajectoires de sortie, j’ai pu questionner leur passage dans deux entités de traitement, les Centres de Soin, d’Accompagnement et de Prévention en Addictologie (CSAPA) et les groupes d’entraide associatifs (Vie Libre, Narcotiques et Alcooliques Anonymes). À partir d’une posture ethnographique, à la fois compréhensive et critique, nous explorons la construction de la « sortie…
Un groupe statuaire complexe à Autun : essai d’identification
2012
Au cours d’un diagnostic réalisé au nord-ouest de la ville d’Autun, à proximité du rempart d’origine augustéenne, un fragment de groupe statuaire a été trouvé au croisement de deux rues antiques. Reposant sur le sol de circulation, il semble avoir été abandonné au cours de l’Antiquité tardive ou du haut Moyen Age. Il se compose d’un personnage cuirassé (cuirasse musclée) vraisemblablement représenté de dos. Il s’agirait d’une gigantomachie, en ronde-bosse (sculpté sur trois cotés), la face principale a été délitée par la cassure de l’arkose taillée en délit (les bancs géologiques locaux sont impuissants à fournir la hauteur nécessaire à ce groupe). Sur ce drapé, on voit se lover dans une at…
