Full textThe work presented in this manuscript aims to study organocatalytic reaction sequences enabling the stereoselective formation of carbon-carbon and carbon-heteroatom bonds. Various strategies have been developped for the preparation of chiral cyclic architectures, which represents an important challenge due to their presence in a vast number of biologically active compounds. This manuscript starts off by introducing the principal of organocatalysis, and more specifically the different activation means used in aminocatalysis.The first chapter focuses on the regio- and diastereoselective synthesis of cyclic hydrazine-containing bicycles in a solvent-free way. The second chapter merges de-aromatization or desymetrization with an aminocatalytic reaction sequence, to yield tridimensional enantioenriched polycycles from unsaturated aldehydes. Lastly, the third chapter concentrates on the synthesis of unsymmetrical sulfamides and their uses as substrates in aminocatalysis

Full textThis work deals with the synthesis of different series of two and three-dimensional conjugated systems in order to lead to new classes of organic semiconductor materials with isotropic optical and charge transport properties. A first part is devoted to the synthesis of conjugated systems derived from 3,4-phenylenedioxythiophene in order to obtain soluble polymers and oligomers analogous to poly (3,4-ethylenedioxythiophene) but without sp3 carbons. The bulk of this work describes the synthesis of different series of molecules of three-dimensional structure built by fixing linear conjugated systems on a central node (silicon, carbon, phosphorus and nitrogen). On the basis of the analysis of the electronic and physicochemical properties of these different classes of compounds, the systems derived from triphenylamine have been the subject of a more advanced synthesis work and several of these compounds have been used as a material. Active for the realization of organic devices such as field effect transistors and solar cells

Full textThis study contributes to a better understanding of the local behaviour and the interaction between a inclusion and a cohesion less material. The physical phenomenon governing this interaction is the friction. A chapter on existing literature describes theoretical and practical aspects of the friction modelling and factors influencing the latter such as dilatancy. The laboratory tests are carried out in several models of different dimensions. - Plane friction tests with standard shear apparatus are used to define a friction angle sand/plate. Influence of the surface of contact is revealed. - Pull out tests of the corner iron of different dimensions are carried out in reduced model. Friction coefficient is defined and calculated. Several factors influencing the latter such as the nature, and method of placing the inclusion are examined. An analysis of the start of the pull out tests is done for tests realized in this model. Pressure cells have been positioned around the inclusion to study the dilatancy. - Pull out tests of cylindrical bar are carried out in another reduced model. The dilatancy is controlled this case by the vertical displacement variation. All results are compared to the ether models

Full textThe visual impact assessment of architectural projects in urban environments is usually based on manual drawings, paintings on photographs, scale models or computer-generated images. These techniques are either too expensive or not realistic enough. Strictly using computer images means requiring an accurate 3D model of the environment. Computing such a model takes a long time and the results lack of visual accuracy. Our technique of overlaying computer generated images onto photographs of the environment is considerably more effective and reliable. This method is a promising solution regarding computation time (no accurate 3D model of the environment) as weIl as visual realism (provided by the photograph itself). Such a solution requires nevertheless to solve lots of problems in order to get geometrical and photometrical coherence in the resulting image. To this end, image analysis and image synthesis methods have to be designed and developed. The method is generalized to produce an animated film, and can furthermore greatly increase the realism of the simulation. My Ph. D. Work was to test and integrate various image analysis and synthesis techniques for the composition of computer generated images with pictures or video film. This report explains the steps required for a realistic encrustation. For each of these steps, various techniques were tested in order to be able to choose the most suitable solutions according to the state of the most recent researches and to the applications we were dealing with (architectural and urban projects). The application of this work was the simulation of the Paris Bridges illumination projects. Concurrently to this work, I present a new method for the interpolation of computer images for the generation of a sequence of images. This method requires no approximation of the camera motion. Since video images are interlaced, sequences of computer images need to be interleaved too. The interpolation technique we propose is capable of doing this
