Our contribution concerns the following three complementary domains : Automatic Differentiation, op- timal shape design for large systems, mesh adaption. In the chapter 1 of the part 1, we expose a method to compute gradients using Automatic Differentiation for a classical optimal shape design problem. We exply how to deduce an exact gradient based on an adjoint state without storing explicitly the Jacobian matrix. The reverse mode of the DA that we propose use much legs memory storage. In the chapter 2 of the part 2, we propose a SQP-like method to solve a class of optimization problems with equality constraints. We use a low cost iteration to solve the state and the adjoint. The new algorithm enables to solve simultaneously the optimality system. This one shot method combines efficiency and robustness. In the chapter 3 of the part 2, we study a new preconditioning strategy for optimal shape design. We build an additive multilevel preconditioning starting from the classical Bramble-Pasciak-Xu principle and from the agglomeration principle. We specify easily the gain of regularity of our preconditioning using only one real parameter. In the chapter 1 of the part 3, we study the problem of the best adapted mesh for a pure interpolation problem. We specify the mesh with a metric and we model the interpolation error. The optimality system solution gives a completely explicite expression of the optimal metric as a function of the function to adapt. In the chapter 2 of the part 3, we extend the method of the previous chapter to the problem of mesh adaption for P. D. E. Our method is based on a rigourous a priori analysis followed by a modelization. We obtain an optimal control formulation with an adjoint state

Despite numerous experimental and clinical studies in the field of cardiac arrest, only 1 to 8% of the patients leave the hospital with good neurological recovery. Therefore, it is necessary to propose new therapeutics to increase survival after cardiac arrest. To achieve this goal, it seems essential to improve the quality of chest compressions during resuscitation and to protect the myocardium and the brain against ischemia reperfusion injuries. In the first part of this work, we evaluated the current practices to assess if they are beneficial to the patients. Thus, based on a new imaging technic of microcirculation, we checked with direct visualization the effects of the intrathoracic pressure regulation on the microcirculation of the organs. Then, this work studied the impact of supraglottic airway devices on cerebral perfusion during cardiopulmonary resuscitation. Finally, we studied the potentially deleterious effects of epinephrine on vital organ perfusion during cardiopulmonary resuscitation. The second part of this work was focused on optimizing vital organ perfusion by a new technique called SNPeCPR. Finally, the last part focused on the protection of reperfusion injury after cardiac arrest by an adaptation of ischemic postconditioning in cardiopulmonary resuscitation

The main problem that occurs on spherical plain bearings is their spherical surfaces wear prediction that can cause their seizure. This wear is linked with the contact pressures field on the spherical bearing surfaces and with the interface tribological behaviour. Several contact pressure optimization tools are copared. To check their representativeness, scattered light photoelasticity and digital volume correlation tests were performed to compare their results to finite element model ones. The tribological behaviour of a spherical plain bearing was studied by performing elementary tests and on scalled bearings to select most efficient couples of coatings for this application. An influence analysis of the bearing design parameters and an optimisation of its spherical profile were performed to highlight improvement ways for the contact pressures distribution particularly for the edge effects attenuation

The research work carried out in this thesis is part of a context of vehicle electrification in response to environmental concerns. This thesis focuses on the modeling and optimization of commutator machines used in powertrains of small electric vehicles. This kind of machines represents an alternate solution due to their competitiveness, robustness and reliability mainly due to the absence of power electronics. Nevertheless, they require compensation windings and commutation poles to improve their performances. Commutator power supply makes it necessary to take into account electrical dynamics in numerical magnetic modeling by finite elements. That is why, it is crucial to develop a model allowing a strong coupling in the sense of the variational formulation, of magnetic problem, external electrical circuit and finally current flow problem at the commutator interface. In this context, the use of a modeling opensource platform ONELAB has led to the development of an original model that performs projection of physical properties and sources on a fixed mesh. This method avoids remeshing during iterative processes such as geometric optimization or movement modeling. This method has led to the dynamic coupling of the magnetic problem and the external electrical circuit to the current flow formulation at the commutator interface as well as to prospects for multi-physical simulations at this interface. Finally, the choice of an optimization algorithm adapted to the numerical models (black box with a high evaluation cost) allowed the development of a tool for the design of commutator machines adapted to many topologies in order to fulfill industrial requirements
