Full textThe use of psycho-technical scores by neuropsychology researchers to test research hypotheses and neuropsychologists to perform memory assessments lacks scientific legitimacy if these scores are not measurements. A neuropsychology researcher who wants to decide between two competing theoretical approaches, by means of a case study, rather should consider whether the theories predict the probability of success in test items belonging to disjoint ranges. This implies that the notion of probability of success of an item by the patient is empirically based (absence of any learning). If learning takes place, especially in a patient with brain-injury, the scientific problem is different since it is to discover what make learning possible. The clinician, the practitioner of neuropsychological tests, participates in his turn to a diagnostic institution obliges to make a selection of patients who will benefit from further examination of their brains. In this perspective, the psycho-technical scores feed a socio-technical system whose legitimacy not expected to be merely scientific but also political. Scientism determining the current conditions of test validation not only masks the political aspect of this system, but also prevents researchers to think about what measuring means (the scoring of a performance is not equivalent to measuring a theoretical quantity). The methodology for this reflection is based on (i) a series of standard studies (validation testing, case study) and (ii) a thorough analysis of the notion of testability of research hypotheses used by neuropsychology researchers, and assumptions underlying measurability of a theoretical quantity

Full textNous étudions tout d'abord deux expressions distinctes du principal opérateur (« multipôle-to-local ») ainsi que les bornes d'erreur associées. Pour ces deux expressions, nous présentons une formulation matricielle dont l'implémentation avec des routines BLAS (Basic Linear Algebra Subprograms) permet d'améliorer fortement l'efficacité de calcul. Dans la gamme de précisions qui nous intéresse, cette approche se révèle plus performante que les améliorations existantes (FFT, rotations et ondes planes), pour des distributions uniformes ou non.
Outre une nouvelle structure de données pour l'octree sous-jacent et des contributions algorithmiques à la version adaptative, nous avons aussi efficacement parallélisé notre méthode en mémoire partagée et en mémoire distribuée. Enfin, des comparaisons avec des codes dédiés justifient l'intérêt de notre code pour des simulations en astrophysique.

Full textSeismic traveltime tomography is an ill-posed optimization problem due to the non-linear relationship between traveltime and velocity model. Besides, the solution is not unique as many models are able to explain the observed data. The non-linearity and non-uniqueness issues are typically addressed by using methods relying on Monte Carlo Markov Chain that thoroughly sample the model parameter space. However, these approaches cannot fully handle the computer resources provided by modern supercomputers. In this thesis, I propose to solve seismic traveltime tomography problems using evolutionary algorithms which are population-based stochastic optimization methods inspired by the natural evolution of species. They operate on concurrent individuals within a population that represent independent models, and evolve through stochastic processes characterizing the different mechanisms involved in natural evolution. Therefore, the models within a population can be intrinsically evaluated in parallel which makes evolutionary algorithms particularly adapted to the parallel architecture of supercomputers. More specifically, the works presented in this manuscript emphasize on the three most popular evolutionary algorithms, namely Differential Evolution, Particle Swarm Optimization and Covariance Matrix Adaptation - Evolution Strategy. The feasibility of evolutionary algorithms to solve seismic tomography problems is assessed using two different data sets: a real data set acquired in the context of hydraulic fracturing and a synthetic refraction data set generated using the Marmousi velocity model that presents a complex geology structure

Full textGenetic algorithms (GAs) are computation methods inspired by evolution. They have drawn much attention as optimization methods in the last two decades. These optimization methods are population-based algorithms which simulate natural evolution. A population is a set of individuals. Each of them represents a candidate solution to the optimization problem. Populations were evolved by applying genetic operators (mutation process, crossing-over process, selection process). When defining a GA we need to choose some parameters probability of mutation, probability of crossover, the selection pressure, the population size and the penalty coefficients. The complexity of the interaction between the parameters make the selection of a perfect tuning/controlling of them very difficult. In order to compare the asymptotical behavior of GAs which have different parameters controlling, we used the theory of the perturbed Markov Chain made by Freidlin and Wentzell in Random perturbations of dynamical systems. In this thesis, we propose different ways to control the GAs parameters

Full textThis work deals with computational contact mechanics between deformable solids. The aim of this work is to improve the performance, the reliability and the robustness of the algorithms and numerical models set in Code_Aster which is finite element code developped by Électricité De France (EDF) for its engineering needs. The proposed algorithms are used to solve high dimensional industrial problems in order to optimize the computational running times. Several solutions techniques are available in the field of computational contact mechanics but they must take into account the difficulties coming from non-smooth aspects due to Signorini-Coulomb laws coupled to large deformations of bodies and material non linearities. Firstly the augmented Lagrangian formulation so-called « stabilized Lagrangian » is introduced. Successively, the mathematical properties of the discrete operators are highlighted and furthermore a novel energetic function is presented. Secondly the kinematical condition with regard to the normal unknowns are reinforced through unconstrained optimization techniques which result to a novel formulation which is so-called « non standard augmented Lagrangian formulation ». Three types of strategies are implemented in the code. The generalized Newton method is developped : it is a method in which all the non linearities are solved in one loop of iterations. The partial Newton method is an hybrid technique between the generalized Newton one and a fixed point method

Full textOur study aims at showing which place, which role and which means are those of the teaching of Japanese as a Foreign Language (JFL) within various institutions. We start from the Japanese linguistic system, in its connection with the French system, with the questioning, as regards to the teaching, brought by the evolution of resources, methodologies and curricula of formation, notably the CEFR. The population that is being studied is composed of students with professional and / or personal objectives, in particular in the LANSAD courses (Foreign Language Teaching for Non-specialists) of universities and “grandes écoles”. Our hypothesis are the following: that teaching fit within the historical and geopolitical conditions of the spread of Japanese language in the world; a better knowledge of the non-specialist student is necessary, given the diversity of the profiles; and a well-considered pedagogical eclecticism must match that diversity. The survey resorts to the analysis of texts, curricula and textbooks, with questionnaires and interviews, as well as the watching of students (written corpus and interactions). Our work should allow to provide a synthesis of the research on the topic and to open didactic prospects
