Contribution à l'estimation non paramétrique des quantiles géométriques et à l'analyse des données fonctionnelles
2008
In this dissertation we study the nonparametric geometric quantile estimation, conditional geometric quantiles estimation and functional data analysis. First, we are interested to the definition of geometric quantiles. Different simulations show that Transformation-Retransformation technique should be used to estimate geometric quantiles when the distribution is not spheric. A real study shows that, data are better modelized by geometric quantiles than by marginal one's, especially when variables that make up the random vector are correlated. Then we estimate geometric quantiles when data are obtained by survey sampling techniques. First, we propose an unbaised estimator, then using lineari…
Measurement of the intergranular corrosion growth kinetics on a 2024 aluminium alloy : new experimental approaches of damage as function of the envir…
2017
Costs of aeronautical maintenance can be reduced by implementation of “smart” inspection strategies integrating predictive data on the evolution of defects such as the propagation rate of intergranular corrosion.In this work, intergranular corrosion damage on 2024 aluminium alloy was characterized by two modes : the “perforating” damage (dissolution of the grain boundary tips) and the “blunting” damage (dissolution of the grain walls in the intergranular cavities). To evaluate the “perforating” damage, a new version of the TFP method (OTFP method) which is more complete, was designed. The OTFP method allows to detect all the intergranular corrosion defects and not only the fastest full pene…

Conscious and nonconscious influences in the sensory domain
2013
Présentation (résumé 1 p.) ; http://www.pangborn2013.com/; International audience; Characterizing the relationships between conscious and unconscious processing is one of the most important goals of cognitive psychology. Renewed interest in the nature of consciousness has reignited long-standing debates about the reach of the unconscious -- the extent to which behaviour can be influenced by knowledge we are not aware of. According to Nisbett & Wilson (1977), subjects can be "(a) unaware of the existence of a stimulus that importantly influenced a response, (b) unaware of the existence of the response, and (c) unaware that the stimulus has affected the response." Many studies have now (argua…
Electronic implementation of a non-linear oscillator subjected to noise : application to the modeling of neuronal information coding
2011
We study the nonlinear FitzHugh-Nagumo model witch describes the dynamics of excitable neural element. It is well known that this system exhibits three different possible responses. Indeed, the system can be mono-stable, oscillatory or bistable. In the oscillatory regime, the system periodically responds by generating action potential. By contrast, in the mono-stable state the system response remains constant after a transient. Under certain conditions, the system can undergo a bifurcation between the stable and the oscillatory regime via the so called Andronov-Hopf bifurcation. In this Phd thesis, we consider the FitzHugh-Nagumo model in the stable state, that is set near the Andronov-Hopf…

La Bourgogne entre les bassins rhénan, rhodanien et parisien : carrefour ou frontière ?
1996
International audience; Au coeur même de son territoire, la région de Bourgogne a accueilli pour quelques jours, à l'occasion de son 18e colloque, la communauté des néolithiciens. Bien des congressistes, venus du Nord, de l'Ouest ou du Sud pour se rendre à Dijon, n'auront pas manqué de percevoir le relatif obstacle au franchissement que constitue le massif bourguignon.Mais le frein partiel engendré par la topographie ne saurait masquer l'ouverture vers l'extérieur de la Bourgogne, naturellement échancrée par trois bassins alluviaux. La Seine, l'Yonne et leurs affluents constituent des vallées propices aux échanges avec le Bassin parisien. Le couloir de la Saône, prolongé par celui du Rhône,…
Le mobilier archéologique de l’habitat du Hallstatt final à Écuelles « Charmoy » (Seine-et-Marne)
2005
The Ecuelles Charmoy site is one of the first Late Hallstatt settlements to be discovered on the edge of the plateau that dominates the Seine-Yonne confluence. In use for only a short period at the end of the 5th and during the first half of the 4th century BC, the site includes postholed buildings, storage pits and other structures in an organized domestic space. The pottery, especially the painted ware, is particularly abundant in the storage pits and constitutes a reference of local ware and its production. Also the traces of metalworking found on the site, be it the reduction of iron or the crafting of moulded bronze jewellery, renews our knowledge of the function and vocation of such a…
