This thesis is about applying microlocal techniques to the construction of Hadamard states for Dirac fields on curved spacetimes with weak conditions on their asymptotical behaviors. In a second time we will focus on the construction of in and out vacuum states and prove their Hadamard property

The optimization of Laplacian eigenvalues is a classical problem. In fact, at the end of the nineteenth century, Lord Rayleigh conjectured that the first eigenvalue with Dirichlet boundary condition is minimized by a disk. This problem received a lot of attention since this first study and research possibilities are numerous: various conditions, geometrical constraints added, existence, description of optimal shapes... In this document we restrict us to Dirichlet and Neumann boundary conditions in R^2 and R^3. We begin with a state of the art. Then we focus our study on disks and balls. Indeed, these are some of the only shapes for which it is possible to explicitly and relatively easily compute the eigenvalues. But we show in one of the main result of this document that they are not minimizers for most eigenvalues. Finally we take an interest in the possible numerical experiments. Since we can do very few theoretical computations, it is interesting to get numerical candidates. Then we can deduce some theoretical working assumptions. With this in mind we give some keys to understand our numerical method and we also give some results obtained

"Evaluation et rééducation des expressions faciales émotionnelles chez l’enfant avec TSA : le projet JEMImE Serious games to teach social interactions and emotions to individuals with autism spectrum disorders (ASD) Children facial expression production : influence of age, gender, emotion subtype, elicitation condition and culture." Thesis, Sorbonne université, 2019. http://www.theses.fr/2019SORUS625.
The autism spectrum disorder (ASD) is characterized by difficulties in socials skills, as emotion recognition and production. Several studies focused on emotional facial expressions (EFE) recognition, but few worked on its production, either in typical children or in children with ASD. Nowadays, information and communication technologies are used to work on social skills in ASD but few studies using these technologies focus on EFE production. After a literature review, we found only 4 games regarding EFE production. Our final goal was to create the serious game JEMImE to work on EFE production with children with ASD using an automatic feedback. We first created a dataset of EFE of typical children and children with ASD to train an EFE recognition algorithm and to study their production skills. Several factors modulate them, such as age, type of emotion or culture. We observed that human judges and the algorithm assess the quality of the EFE of children with ASD as poorer than the EFE of typical children. Also, the EFE recognition algorithm needs more features to classify their EFE. We then integrated the algorithm in JEMImE to give the child a visual feedback in real time to correct his/her productions. A pilot study including 23 children with ASD showed that children are able to adapt their productions thanks to the feedback given by the algorithm and illustrated an overall good subjective experience with JEMImE. The beta version of JEMImE shows promising potential and encourages further development of the game in order to offer longer game exposure to children with ASD and so allow a reliable assessment of the effect of this training on their production of EFE
Canard, Maxime. "Controlled generation of unidirectional irregular sea states in experimental and numerical wave tanks." Electronic Thesis or Diss., Ecole centrale de Nantes, 2024. http://www.theses.fr/2024ECDN0001.
The objective of this thesis is to improve the wave generation and qualification procedures in the context of ocean engineering studies. The framework is limited to unidirectional irregular sea states generated in experimental and numerical wave tanks. Experiments were carried out using the ECN facilities and numerical studies were performed using the nonlinear potential wave solver HOS-NWT developed by ECN. In the first part of the thesis, the problem of irregular wave propagation in wave tank environments is addressed from theoretical, experimental, and numerical points of view. Paticular attention is paid to the evolution in space of the wave spectrum and statistics. In addition, experimental uncertainties arestudied in detail. The second part of the thesis focuses on developing methods to better control the wave fields at any target position in the domain. First, a procedure focusing on the quality of the wave spectrum is studied. Then, facing the dependence of the wave statistics on the target location, a new procedure is developed and tested to better control the statistical distributions independently of the target location
