Neuroimaging investigates the brain's architecture and function using magnetic resonance (MRI). To make sense of the complex observed signal, Neuroscientists posit explanatory models, governed by interpretable parameters. This thesis tackles statistical inference : guessing which parameters could have yielded the signal through the model.Inference in Neuroimaging is complexified by at least three hurdles : a large dimensionality, a large uncertainty, and the hierarchcial structure of data. We look into variational inference (VI) as an optimization-based method to tackle this regime.Specifically, we conbine structured stochastic VI and normalizing flows (NFs) to design expressive yet scalable variational families. We apply those techniques in diffusion and functional MRI, on tasks including individual parcellation, microstructure inference and directional coupling estimation. Through these applications, we underline the interplay between the forward and reverse Kullback-Leibler (KL) divergences as complemen-tary tools for inference. We also demonstrate the ability of automatic VI (AVI) as a reliable and scalable inference method to tackle the challenges of model-driven Neuroscience

The strong demand for results at a detailed geographic level, particularly from national surveys, has raised the problem of the fragility of estimates for small areas. This thesis addresses this issue with specific methods based on the sample design. These ones consist of building new weights for each statistical unit. The first method consists of optimizing the re-weighting of a subsample survey included in an area. The second one is based on the construction of weights that depend on the statistical units as well as the areas. It consists of splitting the sampling weights of the overall estimator while satisfying two constraints : 1/ the sum of the estimates on every partition into areas is equal to the overall estimate ; 2/ the system of weights for a given area satisfies calibration properties on known auxiliary variables at the level of the area. The split estimator thus obtained behaves almost similarly as the well-known blup (best linear unbiased predictor) estimator. The third method proposes a rewriting of the blup estimator, although model-based, in the form of a homogenous linear estimator from a design-based approach. New modified blup estimators are obtained. Their precision, estimated by simulation with an application to real data, is quite close to that of the standard blup estimator. Then, the methods developed in this thesis are applied to the estimation of local mobility indicators from the 2007-2008 French National Travel Survey. When the size of an area is small in the sample, the estimates obtained with the first method are not precise enough whereas the precision remains satisfactory for the two other methods

Survival data arise from disciplines such as medicine, criminology, finance and engineering amongst others. In many circumstances the event of interest can be classified in several causes of death or failure and in some others the event can only be observed for a proportion of "susceptibles". Data for these two cases are known as competing risks and long-term survivors, respectively. Issues relevant to the analysis of these two types of data include basic properties such as the parameters estimation, existence, consistency and asymptotic normality of the estimators, and their efficiency when they follow a semiparametric structure. The present thesis investigates these properties in well established semiparametric formulations for the analysis of both competing risks and long-term survivors. It presents an overview of mathematical tools that allow for the study of these basic properties and describes how the modern theory of empirical processes and the theory of semiparametric efficiency facilitate relevant proofs. Also, consistent variance estimate for both the parametric and semiparametric components for the two models are presented. The findings of this research provide the theoretical basis for obtaining inferences with large samples, the calculation of confidence bands and hypothesis testing. The methods are illustrated with data bases generated through simulations

Applications of dynamic simulators for model predictive controllers design are rather scarce in the litterature. The complexity of solving the resulting optimization problems may explain this lack of popularity. In fact, nonlinear programming algorithms are not always well suited to efficiently reach the optimum of a fundamentaly-based cost function. The situation is even worse when the equations used in the model are unknown by the control designers (black box models). The simulation-based model predictive controller is an alternative formulation to perform model predictive control (MPC) without making use of any explicit optimization solver, but rather based on an easy-to-compute closed-loop simulation. The resulting scheme generally provides a sub-optimal solution and benefits from many interesting features of conventional MPC without being restricted by the model complexity. Two algorithms are proposed: decentralized and decoupled. The decentralized simulation structure allows a flexible setting of the prediction horizon (Hp) that is not possible in the decoupled case, easier to tune, but where Hp must generally be in the same order of magnitude that the system settling time. A second contribution of this thesis is the development of a framework for the dynamic simulation of a mineral separation process: column flotation. Until now, most of the proposed models or simulators were restricted to the steady-state behavior. When dynamic mass-balance equations were considered, a constant pulp level during the simulation was always assumed. The presented framework aims to simulate water, solids and gas motion and their effect on the pulp level and output flow rates. As it often happens in mineral processing, the column flotation process has not benefited from advanced control techniques. This is where the two previous subjects merge. The proposed simulation framework is used to design a simulation-based model predictive controller for process variables having a strong influence on metallurgical results (grade and recovery). A case study is presented where the pulp level, bias and air hold-up in the pulp zone are kept within an acceptable operating region.

In this thesis, two coupling methods are proposed for the multiscale simulation of forming processes. In the first part, a simplified procedure (indirect coupling) is adopted to couple the finite element codes (Abaqus and LAM3) with a polycrystalline selfconsistent model based on the large strain elastoplastic behavior of single crystals. This simplified procedure consists in linking the polycrystalline model with the FE analysis by extracting the history of the increment of macroscopic strain and stress, obtained from a preliminary FE simulation with a phenomenological law, and then using it as loading path prescribed to the polycrystalline model. This method is applied to multiscale simulation of skin-pass processes. By following on the loading path extracted at the halfthickness of the sheet, we can predict the evolution of some physical parameters associated with the plasticity model, in particular the crystallographic texture, the morphological texture and hardening. In the second part on this thesis, a small strain version of the elastoplastic polycristalline self-consistent model is coupled to the Abaqus FE code via the user material subroutine UMAT. This coupling (called direct coupling) consists in using crystal plasticity theory as constitutive law at each integration point of the FE mesh. The polycristal is represented by a set of N single crystals. Each time the FE code needs information on the mechanical behavior at the integration points considered, the full polycrystalline constitutive model is called. In order to validate this coupling, simulations of simple mechanical tests have been conducted. The results of this coupling have been validated through comparison with reference models. Unlike phenomenological models, this coupling provides not only information on the overall macroscopic response of the structure, but also important information related to its microstructure

Transportation systems have to be efficient in terms of energy in order to limit their environmental impact. Electric public transportation, such as subways or tramways, is thus strongly requested in urban areas. Various innovative solutions have emerged recently to increase their energy efficiency (energy storage systems, reversible traction power substations, etc.). However, due to the complexity of the development and optimization of such systems, numerical simulation tools are essential. Nevertheless, simulators of railway systems are particularly delicate to develop due to non-linearity (non-reversibility of traction power substations), non-stationary (displacement of trains), and multiple energetic interactions which exists within these kind of systems. This PhD thesis then proposes a new simulation tool of subway system based on EMR formalism (Energetic Macroscopic Representation). This formalism structures the models according to the energetic properties of the system. It leads to a forward simulation approach with exclusive use of the integral causality. In that way, the proposed simulation tool is stemming from an innovative approach and allows a new vision of subway systems. These approaches allow especially the increasing of the simulator flexibility and the obtaining of physical simulation results. Moreover, this PhD thesis has the particularity to experimentally validate all the developed models
