▼ Internal parasites are a major concern to the livestock industry leading to huge losses. Genetic enhancement of ruminants for resistance/tolerance to internal parasites may provide for a lasting solution to the problem of internal parasite infection in livestock. The objective of this study was to estimate heritability and permanent environmental variance for internal parasite resistance traits in sheep and to apply penalties on the records of treated animals, analyzing the effect of such penalties on the genetic parameters. Records from 1008 Dorper sheep in a private South African flock comprised 17,711 FAMACHA scores, 3,758 fecal egg counts (mostly Haemonchus contortus), and 4,209 hematocrit values that were collected from 1997 – 2000. Animal models were used to conduct single trait analyses. Data were analyzed in three sets: 1) untreated records only; 2) all records; no penalties; and 3) all records with treated records penalized. Heritability estimates of Fc (FAMACHA) ranged from 0.33 ± 0.03 to 0.37 ± 0.03; FEC (Fecal egg count) from 0.04 ± 0.02 to 0.05 ± 0.03 and hematocrit from 0.19 ± 0.04 to 0.20 ± 0.05. Permanent environmental variance as a proportion of phenotypic variance was 0.02 ± 0.02 to 0.03 ± 0.02 for Fc, 0.14 ± 0.04 to 0.18 ± 0.05 for Ht and 0.07 ± 0.02 to 0.08 ± 0.03 for FEC. The Inclusion of treated animal records in the analyses, with or without
penalization did not change the estimates of heritability and permanent environmental variance as a proportion of phenotypic variance.
The objective of the second study was to assess genetic variation in fecal egg count and the associations of fecal egg count with other traits in growing crossbred Nelore-Angus cattle. Records of 201 F2 and F3 ½ Nelore ½ Angus steers in feedlot conditions in a genomics resource population in Central Texas were collected in 2012 and 2013. Helminth egg counts were determined from fecal samples before treatment with an anthelmintic product. The association of fecal egg count with other traits was assessed by modeling each in distinct analyses as a linear covariate. Year explained substantial variation in fecal egg count (P = 0.001). No other investigated covariate (birth weight, weaning weight, weaning temperament score, live weight, temperature, and exit velocity) was important in the different models (P > 0.2). Subsequently, sire (n= 13) was evaluated as a fixed effect (sires with less than 3 steers with records were excluded). Two sire families had significantly lower (P < 0.05) fecal egg counts (1.31 ± 0.28 and 1.57 ± 0.10) than the three sire families with the highest fecal egg counts (1.87 ± 0.10 - 2.06 ± 0.20). These results suggest the presence of additive genetic variation for fecal egg count, implying that selection can be carried out for the ability to suppress parasite worms in cattle.

▼ This dissertation spans three distinct methodological contributions to the econometric and analytic modeling literature. The first chapter is motivated by the challenge of estimating the impact of a customized multi-treatment coupon campaigns on visit rates for a large panel across a two-year trial. Prior literature has highlighted the necessity for both detecting and mitigating the issue of endogeneity. In response, I first develop a novel robust Wald test for idiosyncratic endogeneity in the presence of individual heterogeneity and a time-varying endogenous regressor of restricted range for a nonlinear, unobserved effects model. Building on a prior working paper, I extend the results to tackle the identification of idiosyncratic endogeneity in the presence of time-constant endogeneity for unbalanced panels. I propose a two-stage estimation procedure that tests for positive covariance between time-varying unobservables and a time-varying, binary endogenous variable that completely controls for the latent, time-constant heterogeneity for count responses. Simulations suggest endogeneity detection for both unbalanced panels scenarios mirrors the balanced panel benchmark closely using metrics of rejection rates, nominal size, and statistical power given proper instrumental variables. A nonlinear, instrumental variables GMM procedure is proposed for parameter estimation given positive endogeneity detection. The second chapter studies the estimation of a nonlinear (generalized additive) mixed effects models for count data containing parametric factor smooths. These models are further extended to estimate Poisson responses generated from both stationary and non-stationary conditionally serially correlated AR (1) processes. Simulation studies are used to verify the accuracy of these models in a range of scenarios. The models are then applied to the problem of estimating a carryover effects of a promotional campaigns after promotions end. The final chapter seeks to extend the forecasting combination model of Granger and Ramanathan by approximating the optimal conditional mean solution with conditional quantiles. Useless forecasters at arbitrary quantiles of the response are discarded via a LASSO penalty. The final combination forecast outperforms the equal weight combination benchmark as well as a variety of other combination models in terms of out-of-sample predictive power and other significant performance metrics at the expense of marginally increased forecast variance.

▼ The Vortex Particle-Mesh method has been gaining popularity for many advection-dominated flow simulations, such as wake studies at high Reynolds numbers and external aerodynamics. However, the handling of inner solid boundaries remains an open challenge as the formulation of the boundary condition for the vorticity is not as straightforward as in a classical velocity-pressure formulation. This complexity is further increased since the method relies on a non-body-conforming Cartesian mesh; hence the obstacle may intersect the grid at arbitrary locations. In such a setting, several numerical techniques have been proposed for immersing the geometry into the Cartesian mesh. In this work, we investigate two approaches aimed at addressing this problem: the iterative penalization technique and the Immersed Interface treatment. The iterative penalization enforces the body contribution by adding an additional source term to the Navier-Stokes equations. It results in a non-intrusive way to handle immersed boundaries, yet it leads to inaccurate results. On the contrary, the Immersed Interface treatment is sharp and accurate, as it handles the interface discontinuities on the grid through the evaluation of jumps so as to maintain the order of convergence of the finite difference stencil used. We apply the Immersed Interface tool to the Vortex Particle-Mesh method and prove its accuracy and efficiency on 2D and 3D benchmarks. This method is more intrusive than the iterative penalization approach, yet it is less computationally expensive. It also enables the computation of wall quantities, which are mandatory for fluid-structure interaction applications. Our approach is the first of its kind that enables a flexible, accurate and efficient treatment of solid boundaries for the Vortex Particle-Mesh framework.

▼ A dissertação Criminalização dos sem-abrigo: Abordagens e políticas expõe um cenário
europeu de um problema controverso de escala mundial. Esta investigação apresenta as
perspetivas teóricas de vários autores e confronta o mesmo problema em locais geográficos
diferentes: primeiro analisa-se a realidade das políticas de exclusão dos sem-abrigo nos Estados
Unidos da América e depois na Europa, mais concretamente nos 16 Estados-Membros da União
Europeia. O estudo das abordagens e das políticas em torno da criminalização dos sem-abrigo é
feito através de um método de pesquisa bibliográfico e documental abrangendo diferentes áreas
científicas como a sociologia e o direito. O mapeamento das políticas penais europeias e uma
demonstração e confrontação de diferentes correntes punitivas que se fazem sentir nos dias de
hoje são o foco central deste estudo.
A presente investigação relaciona a evolução social e política das sociedades (urbanas)
modernas e os “novos problemas” resultantes destas. O declínio dos laços sociais, o controlo
social, a vigilância dos espaços públicos, e perda de valores solidários são efeitos que têm estado
em permanente evolução e se fazem sentir nas comunidades urbanas ocidentais. São estes feitos
que se enumeram e analisam ao longo da dissertação.

▼ Dans ce travail de thèse, une méthode de pénalisation en volume pour la simulation d'écoulements magnétohydrodynamiques (MHD) en domaines confinés est présentée. Les équations incompressibles de la MHD résistives sont résolues par le truchement d'un solveur pseudo-spectral parallèlisé. La pénalisation en volume est une méthode de frontières immergées, caractérisée par une grande flexibilité dans le choix de la géométrie de l'écoulement. Dans le cas présent, elle permet d'utiliser des conditions aux limites non-périodiques dans un schéma pseudo-spectral Fourier. La méthode numérique est validée et sa convergence est quantifiée pour des écoulements hydrodynamiques et MHD, en deux et trois dimensions, en comparant les résultats numériques à ceux de la littérature et à des solutions analytiques. Dans un second temps, la génération spontanée de moment cinétique et magnétique est étudiée pour des écoulements MHD confinés 2D et 3D. L'influence du nombre de Reynolds et du rapport des énergies cinétique/magnétique est explorée, ainsi que les différences induites par les conditions aux limites. Le fait que l'axisymétrie des frontières résulte en un terme de pression non-nul est primordial pour engendrer de grandes valeurs du moment cinétique. L'exclusivité de cette auto-organisation aux écoulements 2D est étudiée en considérant la MHD 3D en présence d'un fort champ magnétique axial. La suite est consacrée à la simulation d'un fluide conducteur dans un cylindre avec un forçage magnétique axial et poloidal. En faisant varier l'amplitude du forçage poloidal, différents états dynamiques sont atteints. Enfin, l'effet du nombre de Prandtl sur le seuil des instabilitées est étudié.
A volume penalization method for the simulation of magnetohydrodynamic (MHD) flows in confined domains is presented. Incompressible resistive MHD equations are solved in 3D by means of a parallelized pseudo-spectral solver. The volume penalization technique is an immersed boundary method, characterized by a high flexibility in the choice of the geometry of the considered flow. In the present case, it allows the use of conditions different from periodic boundaries in a Fourier pseudo-spectral scheme. The numerical method is validated and its convergence is assessed for two- and three-dimensional hydrodynamical and MHD flows by comparing the numerical results with those of the literature or analytical solutions. Then, the spontaneous generation of kinetic and magnetic angular momentum is studied for confined 2D and 3D MHD flows. The influence of the Reynolds number and of the ratio of kinetic/magnetic energies is explored, as well as the differences induced by the boundary conditions. The fact that axisymmetric borders introduce a non-zero pressure term in the evolution equation of the angular momentum is essential to generate large values of the angular momentum. It is investigated whether this self-organization is exclusively observed in 2D flows by considering 3D MHD in the presence of a strong axial magnetic field. The last part is devoted to the…

▼ A viscous damage model including two damage variables - a local and a nonlocal one - coupled through a penalty term is investigated on three different levels: unique solvability, behaviour as the
penalization parameter approaches ∞ and optimal control. Existence, uniqueness and regularity of the solutions are proven. In particular, we give an improved result regarding spacial regularity of the nonlocal damage. Lipschitz continuity as well as Fréchet-differentiability of the solution operators are established. We also analyse the behaviour for penalty parameter tending to ∞ of the considered damage model. It turns out that in the limit both damage variables coincide and satisfy a classical viscous damage model. Moreover, we find L∞ bounds for the penalized damage variables and their limit. Further, an optimal control problem governed by the damage model with penalty is considered, where the applied force is used as control. In this context, we
derive necessary optimality conditions for a local optimum. As the associated control-to-state operator is not Gâteaux differentiable, standard adjoint calculus cannot be employed for deriving an optimality system. This was however possible under the strict complementarity assumption.

▼ Longitudinal data analysis is common in biomedical research area. Generalized estimating equations (GEE) approach is widely used for longitudinal marginal models. The GEE method is known to provide consistent regression parameter estimates regardless of the choice of working correlation structure, provided the square root of n consistent nuisance parameters are used. However, it is important to use the appropriate working correlation structure in small samples, since it improves the statistical efficiency of β estimate. Several working correlation selection criteria have been proposed (Rotnitzky and Jewell, 1990; Pan, 2001; Hin and Wang, 2009; Shults et. al, 2009). However, these selection criteria have the same limitation in that they perform poorly when over-parameterized structures are considered as candidates. In this dissertation, new working correlation selection criteria are developed based on generalized eigenvalues. A set of generalized eigenvalues is used to measure the disparity between the bias-corrected sandwich variance estimator under the hypothesized working correlation matrix and the model-based variance estimator under a working independence assumption. A summary measure based on the set of the generalized eigenvalues provides an indication of the disparity between the true correlation structure and the misspecified working correlation structure. Motivated by the test statistics in MANOVA, three working correlation selection criteria are proposed: PT (Pillai's trace type criterion),WR (Wilks' ratio type criterion) and RMR (Roy's Maximum Root type criterion). The relationship between these generalized eigenvalues and the CIC measure is revealed. In addition, this dissertation proposes a method to penalize for the over-parameterized working correlation structures. The over-parameterized structure converges to the true correlation structure, using extra parameters. Thus, the true correlation structure and the over-parameterized structure tend to provide similar variance estimate of the estimated β and similar working correlation selection criterion values. However, the over-parameterized structure is more likely to be chosen as the best working correlation structure by "the smaller the better" rule for criterion values. This is because the over-parameterization leads to the negatively biased sandwich variance estimator, hence smaller selection criterion value. In this dissertation, the over-parameterized structure is penalized through cluster detection and an optimization function. In order to find the group ("cluster") of the working correlation structures that are similar to each other, a cluster detection method is developed, based on spacings of the order statistics of the selection criterion measures. Once a cluster is found, the optimization function considering the trade-off between bias and variability provides the choice of the "best" approximating working correlation structure. The performance of our proposed criterion measures relative to other relevant criteria (QIC, RJ…

▼ Singular value decomposition is a widely used tool for dimension reduction in multivariate analysis. However, when used for statistical estimation in high-dimensional low rank matrix models, singular vectors of the noise-corrupted matrix are inconsistent for their counterparts of the true mean matrix. We suppose the true singular vectors have sparse representations in a certain basis. We propose an iterative thresholding algorithm that can estimate the subspaces spanned by leading left and right singular vectors and also the true mean matrix optimally under Gaussian assumption. We further turn the algorithm into a practical methodology that is fast, data-driven and robust to heavy-tailed noises. Simulations and a real data example further show its competitive performance. The dissertation contains two chapters. For the ease of the delivery, Chapter 1 is dedicated to the description and the study of the practical methodology and Chapter 2 states and proves the theoretical property of the algorithm under Gaussian noise.

▼ Les écoulements autour de structures en mouvement font l'objet de plusieurs travaux numériques et expérimentaux. L'objectif de ce travail de thèse consiste à montrer la pertinence de la combinaison de la pénalisation volumique avec la méthode de lattice Boltzmann (LBM), dans l'étude du mouvement d'obstacles mobiles dans un écoulement, et de leur interaction avec celui-ci. La LBM,qui est simple et précise à mettre en œuvre, a prouvé ces dernières années son efficacité dans le domaine de la mécanique des fluides. Par ailleurs, la méthode de pénalisation volumique consiste à introduire un terme de pénalisation dans l'équation que l'on souhaite résoudre, afin de prendre en compte l'influence de l'obstacle sur le domaine fluide. Comme cette équation est résolue sur l'ensemble du domaine composé du fluide et du solide, les conditions aux limites à l'interface fluide-solide sont appliquées de façon naturelle. Il semble donc aisé de combiner cette technique avec la méthode de lattice Boltzmann. Nous avons dans un premier temps rappelé les notions de base et les principales caractéristiques de la méthode de lattice Boltzmann. On a présenté quelques exemples d'applications sur des cas tests, que nous avons programmés. Ensuite, une étude bibliographique faisant état des différentes approches qui utilisent la LBM dans l'étude des problèmes d'interaction fluide structure (IFS) a été réalisée. Puis, la combinaison de la pénalisation volumique avec la LBM a été testée avec succès sur l'équation de Burgers monodimensionnelle. La validation s'est portée en premier lieu, sur un écoulement autour d'un solide fixe, puis sur un écoulement autour d'une structure dont le mouvement est imposé, et finalement sur un problème d'IFS de type masse-ressort. La méthode développée a été ensuite testée sur les équations de Navier-Stokes, en considérant un fluide incompressible et une structure rigide. La validation s'est portée tout d'abord sur un écoulement autour d'obstacles immobiles (carré et cylindre), puis autour d'un cylindre mobile en oscillations forcées et libres. Enfin, une dernière application a été portée sur un écoulement entre deux plaques mobiles dans un canal. Nous avons montré que pour tous les cas étudiés, l'approche développée donne de bons résultats, elle reproduit avec précision les résultats de référence.
Flows around moving bodies are the subject of several numerical and experimental studies. The work presented in this document deals with the implementation of a volume penalization technique in a lattice Boltzmann model (LBM), in order to compute flows around moving obstacles. The LBM, which is accurate and easy to implement, has been successfully applied in fluid mechanics during the last decades. It was thus chosen in the present work, for flow computation. Furthermore, the volume penalization technique consists in introducing a volume penalization term into the equation that needs to be solved, in order to take into account the influence of the obstacle on the fluid domain. Since this equation is solved on both fluid…

▼ Estrategias de penalização são muito utilizadas no trato de problemas com restrições. Problemas inerentes a escolha de valores adequados para os termos de penalização dificultam a obtenção de resultados contáveis e robustos na sua aplicação em problemas da otimização estrutural. Tecnicas baseadas em modelos de penalização adaptativa tem apresentado relativo sucesso quando aplicadas em conjunto com algoritmos evolucionistas. Apresenta-se aqui uma nova alternativa utilizando uma estrategia de lagrangeano aumentado para o trato das restrições do problema de otimização estrutural. Encontra-se na literatura modelos para penalização adaptativa bem como o uso do lagrangeano aumentado em conjunto com algoritmos geneticos geracionais. O objetivo desse trabalho e adaptar um modelo de penalização para um algoritmo genetico não geracional, bem como criar um algoritmo baseado em lagrangeano aumentado tambem para o algoritmo não-geracional. Esses algoritmos foram aplicados em estruturas reticuladas, muito utilizadas na construção civil como coberturas de ginasios, hangares, galpões, etc. O desempenho desses tipos de estruturas e funções matemáticas foi analisado com as tecnicas de tratamento de restrição apresentadas nesse trabalho. Isso foi feito durante a busca de soluções otimas na tentativa de minimizar os custos e satisfazer as restrições adequadas para diversas estruturas e funções matematicas.
Penalty strategies are widely used in dealing with problems with constraints. Problems inherent in the choice of appropriate values for the terms of penalties dicult to obtain reliable and strong results in its application in problems of structural optimization. Techniques based on models of adaptive penalty has shown some success when applied in conjunction with evolutionary algorithms. Here is presented a new alternative using augmented Lagrangian strategy for dealing with the problem of constrained structural optimizations. It is found in the literature models for adaptive penalties as well as the use of the augmented Lagrangian together with generational genetic algorithms. The aim of this work is to adapt a model of penalization for non-generational genetic algorithm, as well as create an algorithm based on augmented Lagrangian as also for a non-generational algorithm. These algorithms were applied to structures, widely used in construction as coverage of gymnasiums, hangars, etc. The performance of these types of structures and functions was analyzed using mathematical techniques for handling constraints presented in this work. This was done during the search for optimal solutions in an attempt to minimize costs and satisfy the constraints appropriate for various structures and mathematical functions.

▼ Nul ne conteste la nature compensatrice de la responsabilité civile. Pourtant, si cette fonction réparatrice n’est guère discutée, les auteurs se séparent aujourd’hui sur le point de savoir si cette fonction doit être la seule assumée par la responsabilité civile. Non qu’il soit contesté qu’elle assume bien d’autres fonctions ; la grande majorité de la doctrine indique en effet, sans toutefois en souligner les ressorts, que les buts poursuivis par la responsabilité sont multiples et relèvent tant de la compensation des préjudices que de la punition et de la dissuasion des comportements dommageables. A l’heure d’une crise de la responsabilité dénoncée par tous, la question touche donc aux rôles que la responsabilité civile doit assumer. Alors que certains auteurs plaident pour un recentrage dur sa mission première d’indemnisation des victimes, de plus en plus de voix plaident au contraire pour l’élargissement de ses fonctions dans un sens à la fois plus répressif mais aussi préventif. Il s’agit donc désormais d’envisager la responsabilité civile comme un véritable outil de gestion des risques. Totalement axée sur l’indemnisation des victimes depuis plusieurs décennies, la responsabilité civile semble paradoxalement mal armée pour répondre à cette nouvelle attente. De plus, un élargissement des fonctions de la responsabilité civile conduit à s’interroger sur la prééminence d’une fonction sur l’autre ou à leur possible conciliation. En réalité, il existe sans conteste un terreau favorable au développement d’une véritable fonction punitive de la responsabilité civile et l’on constate un double mouvement qui nous semble révélateur du rôle régulateur qu’elle peut assumer. En premier lieu, si l’effet punitif diffus que l’on attachait traditionnellement à la condamnation civile est en net recul, sous l’effet du repli de la faute mais aussi des règles gouvernant la réparation, cet effet subsiste néanmoins, comme le démontre notamment l’analyse économique de la responsabilité. Nous avons donc mis en évidence une résistance latente mais bien réelle d’une conception morale de la responsabilité civile servant son objectif normatif. Surtout, nous avons constaté qu’à cet effet secondaire de la responsabilité tend aujourd’hui à se substituer une véritable fonction punitive et dissuasive de la condamnation civile, construite et cohérente. Nous avons donc proposé une lecture renouvelée du fonctionnement de la responsabilité civile après avoir relevé les germes quelque peu épars de cette conception normative de la responsabilité civile : évolution de la notion de préjudice réparable avec notamment l’assouplissement des critères du préjudice réparable en droit des affaires ou l’émergence de nouveaux préjudices comme en matière environnementale ; modification de l’évaluation et des modalités de la réparation ; émergence de la notion de peine privée. Deux méthodes semblent envisageables afin de soutenir la résurgence de la fonction dissuasive et punitive de la responsabilité civile : la première tient à un alourdissement de la…

▼ The importance of network-based approach to identifying biological markers for diag-
nostic classification and prognostic assessment in the context of microarray has been
increasingly recognized. Standard methods treat all genes independently and identically
a priori and ignore the biological observation that genes function together in biological
processes. For binary classification, we are motivated to improve predictive accuracy
and gene selection by developing novel network-based classification tools that explicitly
incorporate interrelationships of genes as described by gene networks.
We propose three network-based support vector machines (SVM) by suitably forming
the penalty term. The neighboring-gene (NG) penalty groups pairwise gene neighbors
and sums up the L1-norm of each group over the entire network, leading to NG-SVM.
NG-SVM tends to select pairs of neighboring genes. The disease-gene-centric (DGC)
penalty is constructed on groups defined on an upper-lower hierarchy imposed on the
undirected network. DGC-SVM aims to detect collectives of genes clustering together
and around some key disease genes. The truncated L1-norm (TL1) penalty intends
to correct bias induced by penalization through a threshold parameter C > 0 built
into the L1-norm as used in NG-SVM and DGC-SVM. Simulation studies and real
data applications demonstrate that the proposed methods are able to capture more
disease genes and less noise genes than the existing popular methods, standard SVM
and L1-SVM. We conclude that the proposed methods have the potential to be effective
classification tools for microarrays and other high-dimensional data.

▼ A data-driven method of generalized adaptive ridge (GAR) for an automatic yet adaptive regression shrinkage and selection was proposed as the first part of this dissertation. In theory, GAR was proved to be equivalent to adaptive- LASSO,
ridge and elastic net under appropriate conditions. Simulation results indicated GAR performs either better or equivalent to these methods, in terms of both prediction accuracy and computational speed due to its flexibility of our newly developed
algorithm. The second part of this dissertation is on a general adaptive L2-regularized optimization problem for a general loss function. This adaptive L2 penalty term was proved to be equivalent adaptive L1 penalty, adaptive L2 penalty, and combined
adaptive L1 and L2 penalty with appropriate choice of parameters and assuming loss function is differentiable. Two algorithms using Newton-Raphson method for the case of the number of predictors (p) less than the number of sample size (n), and sequential
minimal optimization (SMO) method for the case p>n and correlated data were developed. The efficacy of this approach was illustrated by simulations, comparisons with other methods and real data analysis. The last part of this dissertation is about
adaptive three-way decomposition (ATWD) which combines the adaptive approach in the first part of this dissertation and popular three-way decomposition (TWD) in chemical sciences to analyze nuclear magnetic resonance (NMR) data. This method can be used
to reduce the effects of signal noises and dimensionality of the spectral data, provide efficient estimates of spectral components, interpret all the signals retrieved from NMR data, and translate structural information efficiently. Its effective
usefulness were illustrated in both simulation studies and real data analysis.

▼ Evidence in literature demonstrates that use of artificial composite materials provides for a greater potential in designing new electromagnetic/RF devices. However, existing studies dealing with design optimization for RF applications focused to a large extent on shape or geometry design only. So far, material and topology optimization has not been pursued primarily due to the challenges associated with the fabrication of inhomogeneous materials and the limited access to versatile and efficient analysis tools. There are very few examples in the literature on topology optimization of electrical devices and these have dealt with problem specific, restricted or semi-analytic tools for magneto-static applications. The goal of this thesis is to develop a general design method that draws from a broader class of design solutions as compared to conventional design methods and is capable of achieving topology and material designs for new electromagnetic devices that may yield much higher performance. In this dissertation, a topology optimization method based on the Solid Isotropic Material with
Penalization Method (SIMP) is extended to develop full three-dimensional topology designs for electromagnetic scattering and radiation devices. The design problem is formulated in a non-linear optimization framework and is integrated with a fast full wave finite element - boundary integral (FE-BI) simulator. Sequential Linear Programming (SLP) is used to solve the optimization problem with the sensitivity analysis based on the adjoint variable method for complex variables. The sensitivity analysis is derived, verified and integrated into the simulator for the transmission coefficient and input impedance functions of FSS filters and patch antennas, respectively. The performance of high contrast composite material substrates supporting a patch antenna is studied before the proposed design procedure is presented. One such substrate is fabricated and measured using Micro Fabricated Co-Extrusion (MFCX). The capability of the proposed design method is demonstrated by three design examples. One of the examples refers to the dielectric material distribution for a spectral filter with bandpass behavior. In the second example, the dielectric material distribution of the substrate for a patch antenna
subject to pre-specified bandwidth and miniaturization criteria is designed. The optimized design is post-processed via adaptive image filtering and is transformed into a two-material composite for manufacturability. The final substrate is manufactured using Thermoplastic Green Machining as a composite of Low Temperature Co-firing Ceramic (LTCC) filled with air. Finally, the same antenna is designed simultaneously for its patch topology and volumetric dielectric material distribution. Results from both the spectral filter and miniaturized antenna case studies show that the proposed design method is capable of designing full three-dimensional volumetric material textures and printed conductor topologies for filters and patch antennas with…

▼ Ce manuscrit se concentre sur deux problèmes d'estimation de fonction. Pour chacun, une garantie non asymptotique des performances de l'estimateur proposé est fournie par une inégalité d'oracle. Pour l'estimation de densité conditionnelle, des mélanges de régressions gaussiennes à poids exponentiels dépendant de la covariable sont utilisés. Le principe de sélection de modèle par maximum de vraisemblance pénalisé est appliqué et une condition sur la pénalité est établie. Celle-ci est satisfaite pour une pénalité proportionnelle à la dimension du modèle. Cette procédure s'accompagne d'un algorithme mêlant EM et algorithme de Newton, éprouvé sur données synthétiques et réelles. Dans le cadre de la régression à bruit sous-gaussien, l'agrégation à poids exponentiels d'estimateurs linéaires permet d'obtenir une inégalité d'oracle en déviation, au moyen de techniques PAC-bayésiennes. Le principal avantage de l'estimateur proposé est d'être aisément calculable. De plus, la prise en compte de la norme infinie de la fonction de régression permet d'établir un continuum entre inégalité exacte et inexacte.
This manuscript focuses on two functional estimation problems. A non asymptotic guarantee of the proposed estimator’s performances is provided for each problem through an oracle inequality.In the conditional density estimation setting, mixtures of Gaussian regressions with exponential weights depending on the covariate are used. Model selection principle through penalized maximum likelihood estimation is applied and a condition on the penalty is derived. If the chosen penalty is proportional to the model dimension, then the condition is satisfied. This procedure is accompanied by an algorithm mixing EM and Newton algorithm, tested on synthetic and real data sets. In the regression with sub-Gaussian noise framework, aggregating linear estimators using exponential weights allows to obtain an oracle inequality in deviation,thanks to pac-bayesian technics. The main advantage of the proposed estimator is to be easily calculable. Furthermore, taking the infinity norm of the regression function into account allows to establish a continuum between sharp and weak oracle inequalities.

▼ Penalization and sparse model selection have become topics of intense research interest in the era of big data, newly available through ubiquitous computing power, advancing data collection technologies, and internet connectivity. In genomics, chromatin immunoprecipitation, microarrays, and next generation sequencing have made available a wealth of information which continues to accumulate and which we have only begun to understand and fully utilize. We propose two penalized Bayesian tech- niques, one to select a sparse set of DNA binding factors (DBFs) from a large library with enriched binding to the genome in a set of regions of interest and to predict joint binding landscapes for the selected DBFs, and another to predict gene expression from joint binding landscapes.Cellular processes are controlled, directly or indirectly, by the binding of hundreds of different DBFs to the genome. One key to deeper understanding of the cell is discovering where, when, and how strongly these DBFs bind to the DNA sequence. Direct measurement of DBF binding sites (e.g. through ChIP-Chip or ChIP-Seq experiments) is expensive, noisy, and not available for every DBF in every cell type. Naive and most existing computational approaches to detecting which DBFs bind in a set of genomic regions of interest often perform poorly, due to the high false discovery rates and restrictive requirements for prior knowledge.We develop a penalized iterative sampling Bayesian method for identifying DBFs active in the considered regions and predicting a joint probabilistic binding land- scape. Utilizing a sparsity penalization, SparScape is able to select a small subset of DBFs with enriched binding sites in a set of DNA sequences from a much larger candidate set. This substantially reduces the false positives in prediction of binding sites. Analysis of ChIP-Seq data in mouse embryonic stem cells (ESCs) and simu- lated data show that SparScape dramatically outperforms the naive motif scanning method and the comparable computational approaches in terms of DBF identification and binding site prediction.We also propose an extension of Bayesian treed regression to predict gene expres- sion from joint binding landscapes. Rather than sampling from the space of possible partitioning trees, we follow a broad optimization approach, forking the growing partitioning tree at each possible split if multiple possible splits yield similar results in the given objective function. After growing the tree, we select variables at each leaf node of each forked partitioning tree, then take the union of these selected variables and the splitting variables at each internal node and re-grow the partitioning tree considering only the selected variables.

▼ Pour concevoir les futurs réacteurs à fusion nucléaire, une bonne compréhension des mécanismes régissant l'intéraction plasma-paroi est requise. En particulier, il est nécessaire d'estimer quantitativement les flux de chaleurs impactant les matériaux et la contamination du coeur par les impuretés provenant du mur. Dans ce contexte, le code fluide SolEdge2D a été développé pour simuler le transport dans le plasma de bord. L'interaction plasma-paroi est prise en compte grâce à une méthode de pénalisation innovante et originale. Cette méthode permet en particulier de modéliser la géométrie complexe des éléments face au plasma avec une grande flexibilité. En parallèle, une étude plus théorique sur les propriétés du transport dans les milieux faiblement collisionels a été conduite avec les physiciens du groupe CSDC de l'université de Florence. Une généralisation de la loi de Fourier prenant en compte les corrélation spatio-temporelle à longue distance à été obtenue par l'analyse de modèles stochastiques 1D. Cette loi retrouve en particulier la transition entre un régime diffusif à forte collisionalté et un régime balistique à faible collisionalité.
In the scope of designing future nuclear fusion reactors, a clear understanding of the plasma-wall interaction is mandatory. Indeed, a predictive estimation of heat flux impacting the surface and the subsequent emission of impurities from the wall is necessary to ensure material integrity and energy confinement performances. In that perspective, the fluid code SolEdge2D has been developed to simulate plasma transport in the tokamak edge plasma. The plasma-wall interaction is modeled using an innovative penalization technique. This method enables in particular to take complex plasma facing components geometry into account. In parallel to this numerical effort, a theoretical work has been achieved to find appropriate corrections to fluid closures when collisionality drops. The study of stochastic 1D models has been realized in collaboration with physicists from the CSDC group in Florence. A generalized Fourier law taking long range spatio-temporal correlations has been found to properly account for ballistic transport in the low collisional regime. This formulation is expected to be used to model parallel heat flux or turbulent cross-field transport in tokamak plasmas.

▼ Les travaux présentés dans ce manuscrit se concentrent sur l'approximation numérique des équations de la magnétohydrodynamique (MHD) et sur leur stabilisation pour des problèmes caractérisés par des nombres de Reynolds cinétique élevés ou par des écoulements multiphasiques. Nous validons numériquement un nouveau modèle de Simulation des Grandes Echelles (ou Large Eddy Simulations, LES), dit de viscosité entropique, sur des écoulements de cylindre en précession ou créés par des turbines contra-rotatives (écoulement de Von Kármán). Ces études sont réalisées avec le code MHD SFEMaNS développé par J.-L. Guermond et C. Nore depuis 2002 pour des géométries axisymétriques. Ce code est basé sur une décomposition spectrale dans la direction azimutale et des éléments finis de Lagrange dans un plan méridien. Nous adaptons une méthode de pseudo-pénalisation pour prendre en compte des turbines en mouvement, ce qui étend le code SFEMaNS à des géométries quelconques. Nous présentons aussi une méthode originale d'approximation des équations de Navier-Stokes à densité variable qui utilise la quantité de mouvement comme variable et la viscosité entropique pour stabiliser les équations de la masse et du mouvement.
The investigations presented in this manuscript focus on the numerical approximation of the magnetohydrodynamics (MHD) equations and on their stabilization for problems involving either large kinetic Reynolds numbers or multiphase flows. We validate numerically a new Large Eddy Simulation (LES) model, called entropy viscosity, on flows driven by precessing cylindrical containers or counter-rotating impellers (Von Kármán flow). These studies are performed with SFEMaNS MHD-code developed by J.-L. Guermond and C. Nore since 2002 for axisymmetric geometries. This code is based on a spectral decomposition in the azimuthal direction and a Lagrange finite element approximation in a meridian plane. We adapt a pseudo-penalization method to report the action of rotating impellers that extends the range of SFEMaNS's applications to any geometry. We also present an original approximation method of the Navier-Stokes equations with variable density. This method uses the momentum as variable and stabilizes both mass and momentum equations with the same entropy viscosity.

▼ La prédiction de mouvement de solide évoluant dans un fluide présente un réel intérêt pour des applications industrielles telle que l’accrétion de glace sur des surfaces aérodynamiques. Dans ce contexte, en considérant des systèmes de dégivrage, la prévision des trajectoire de glace est nécessaire pour éviter des risques de collision/ingestion de glace sur/dans des zones sensibles de l’avion. Ce type d’application soulève de nombreux challenges d’un point de vue numérique, en particulier concernant la génération/l’adaptation de maillage au cours du mouvement du solide dans le domaine. Pour gérer ces difficultés, dans cette étude, les solides sont définis de manière implicite via une fonction level set. Une méthode de type frontière immergée, appelée Pénalization, est utilisée pour imposer les conditions de bords. Pour améliorer la précision de l’interface, les équations sont résolues sur des maillages non structurés adaptatifs. Cela permet d’obtenir un raffinement proche des bords du solide et ainsi d’améliorer sa définition, permettant un meilleure impositions des conditions de bord. Pour économiser du temps de calcul, et éviter de coûteuses étapes de remaillage/interpolation, la stratégie adoptée pour les simulations instationnaires est d’utiliser une adaptation de maillage à connectivité constante, aussi appelée r-adaptation.
The prediction of solid motion evolving in a fluid presents a real interest for engineering application such as ice accretion on aerodynamics bodies.In this context, considering de-icing systems, the ice shedding trajectory is needed to prevent the risk of collision/ingestion of the ice in/with some sensitive part of the aircraft. This application raises many challenges from a numerical point of view, especially concerning mesh generation/adaptation as the solid moves in the computational domain. To handle this issue, in this work the solids are known implicitly on the mesh via a level set function. An immersed boundary method, called penalization, is employed to impose the wall boundary conditions. To improve the resolution of these boundaries, the equations are solved on adaptive unstructured grids. This allows to have are finement close to the solid boundary and thus increases the solid definition,leading to a more accurate imposition of the wall conditions. To save computational time, and avoid costly remeshing/interpolation steps, the strategy chosen for unsteady simulations is to use a constant connectivity mesh adaptation,also known as r-adaptation

▼ Dans cette thèse nous mettons en oeuvre une méthode vortex hybride pénalisée (HVP) afin desimuler des écoulements incompressibles autour de corps non profilés dans des milieux complexessolides-fluides-poreux. Avec cette approche particulaire hybride, le phénomène de convection estmodélisé à l’aide d’une méthode vortex afin de bénéficier du caractère peu diffusif et naturel desméthodes particulaires. Un remaillage des particules est alors réalisé systématiquement sur unegrille cartésienne sous-jacente afin d’éviter les phénomènes de distorsion. D’autre part, les effetsdiffusifs et d’étirement ainsi que le calcul de la vitesse sont traités sur la grille cartésienne, àl’aide de schémas eulériens. Le traitement des conditions de bords aux parois de l’obstacle esteffectué à l’aide d’une technique de pénalisation, particulièrement bien adaptée au traitementde milieux solides-fluides-poreux.Cette méthode HVP est appliquée au contrôle passif d’écoulement. Cette étude de contrôleest effectuée respectivement en 2D et en 3D autour d’un demi-cylindre et d’un hémisphère parl’ajout d’un revêtement poreux à la surface de l’obstacle. La présence de cette couche poreusemodifiant la nature des conditions aux interfaces, permet de régulariser l’écoulement global etde diminuer la traînée aérodynamique de l’obstacle contrôlé. A travers des études paramétriquessur la perméabilité, l’épaisseur et la position du revêtement poreux, ce travail vise à identifier desdispositifs de contrôles efficaces pour des écoulements autour d’obstacles comme des rétroviseursautomobiles.
In this work we use a hybrid vortex penalization method (HVP) to simulate incompressibleflows past bluff bodies in complex solid-fluid-porous media. In this hybrid particle approach,the advection phenomenon is modeled through a vortex method in order to benefit from thenatural description of the flow supplied by particle methods and their low numerical diffusionfeatures. A particle remeshing is performed systematically on an underlying Cartesian grid inorder to prevent distortion phenomena. On the other hand, the viscous and stretching effects aswell as the velocity calculation are discretized on the mesh through Eulerian schemes. Finally,the treatment of boundary conditions is handled with a penalization method that is well suitedfor the treatment of solid-fluid-porous media.The HVP method is applied to passive flow control. This flow control study is realized pasta 2D semi-circular cylinder and a 3D hemisphere by adding a porous layer on the surface of thebody. The presence of such porous layer modifies the characteristics of the conditions at theinterfaces and leads to a regularization of the wake and to a decrease of the aerodynamic dragof the controlled obstacle. Through parametric studies on the permeability, the thickness andthe position of the porous coating, this works aims to identify efficient control devices for flowsaround obstacles like the rear-view mirrors of a ground vehicle.

▼ The thesis explores possibilities of applying genetic algorithms on the problem of finding the optimal prestressed concrete tendon path. The objective of the thesis is to develop a genetic algorithm based on the Automatic Dynamic
Penalization method and to test its robustness on selected analytical functions. Subsequently, the algorithm is connected to a Time Dependent Analysis module for the computation of prestressed concrete structure to solve selected examples of prestressed beams in the form of a constrained optimization problem. The algorithm is developed in the Python programming language with the help of the Distributed Evolutionary Algorithm library.

▼ Dans de nombreux domaines d’application, les données récoltées correspondent à des courbes. Ce travail se concentre sur l’analyse de courbes de spectrométrie, constituées de plusieurs centaines de variables ordonnées, correspondant chacune à une valeur d’absorbance associée aux nombres d’ondes mesurés. Dans ce contexte, une méthode de traitement statistique automatique est développée, avec pour objectif la construction d’un modèle de prédiction prenant en compte l’hétérogénéité des données observées. Plus particulièrement, un modèle de diagnostic d’une maladie métabolique est établi à partir de courbes mesurées sur des individus provenant d’une population constituée de profils de patients différents. La procédure développée permet de sélectionner l’information pertinente sous forme de portions de courbes discriminantes, puis de construire de façon simultanée une partition des données et un modèle de prédiction parcimonieux grâce à un mélange de régressions pénalisées adapté aux données fonctionnelles. Ces données étant complexes, tout comme le cas d’application étudié, une méthode permettant une meilleure compréhension et une meilleure visualisation des interactions entre les portions de courbes a par ailleurs été développée. Cette méthode se base sur l’étude de la structure des matrices de covariance, avec pour but de faire ressortir des blocs de dépendances entre intervalles de variables. Un cas d’application médicale est utilisé pour présenter la méthode et les résultats, et permet l’utilisation d’outils de visualisation spécifiques.
In many application fields, data corresponds to curves. This work focuses on the analysis of spectrometric curves, composed of hundreds of ordered variables that corresponds to the absorbance values measured for each wavenumber. In this context, an automatic statistical procedure is developped, that aims at building a prediction model taking into account the heterogeneity of the observed data. More precisely, a diagnosis tool is built in order to predict a metabolic disease from spectrometric curves measured on a population composed of patients with differents profile. The procedure allows to select portions of curves relevant for the prediction and to build a partition of the data and a sparse predictive model simultaneously, using a mixture of penalized regressions suitable for functional data. In order to study the complexity of the data and of the application case, a method to better understand and display the interactions between variables is built. This method is based on the study of the covariance matrix structure, and aims to highlight the dependencies between blocks of variables. A medical example is used to present the method and results, and allows the use of specific visualization tools.

▼ In achieving structural patterns in parameters, we focus on two challenging cases in which (1) hierarchical sparsity pattern is desired such that one group of parameters is set to zero whenever another is set to zero; and (2) many features that are counts of rarely occurring events are present, and appropriate aggregation of the rare features may lead to better estimation. In either case, the methods under consideration use a tree or a directed acyclic graph (DAG) that encodes relations among parameters as side information. For achieving hierarchical sparsity patterns in parameters, we investigate the differences between group lasso (GL) and latent overlapping group lasso (LOG) in terms of their statistical properties and computational efficiency. We highlight a phenomenon of GL in which parameters embedded deep within the DAG are more aggressively regularized than those that are less deeply embedded. By contrast, we show that using LOG fulfills our goal without any additional complication and performs, both in practice and in theory, very similarly to the GL penalty that is modified to curb its over-aggressiveness. In terms of computation, we derive a finite-step algorithm for the proximal operator of LOG in the case of the DAG being a directed path graph; we later exploit this efficiency to propose a novel path-based block coordinate descent scheme. Finally, we compare the two frameworks in estimating banded covariance matrix, where we introduce a new sparsely-banded estimator using LOG, which we show achieves the statistical advantages of an existing GL-based method but is simpler to express and more efficient to compute. Another kind of sparsity we care about is sparsity in the data itself. It is prevalent to have many highly sparse features for counting frequency of rare events in diverse areas, ranging from natural language processing (e.g., rare words) to biology (e.g., rare species). We show, both theoretically and empirically, that not explicitly accounting for the rareness of features can greatly reduce the effectiveness of an analysis. We propose a tree-guided framework for aggregating rare features into denser ones through solving a convex optimization problem. The tree, which encodes feature similarity information on the leaves, comes from prior knowledge or data sources external to the current problem and is used as side information in aggregation. In our proposal, aggregating rare features is equivalent as enforcing equal coefficients within each group learned from solving the convex problem, resulting in another case of structural pattern in parameters. We apply our method on two data sets: a TripAdvisor hotel review data set, in which we predict the numerical rating of a hotel based on the text of an associated review; and a microbiome data set from the American Gut project that measures microbial species abundance from fecal samples, in which we predict the one's BMI based on both microbiome and non-microbiome features. In both applications, our method achieves high accuracy by making effective use…

▼ Ce travail est motivé par la nécessité de mieux comprendre la technique de récupération du pétrole par injection de polymères à l'échelle du pore. On considère deux fluides immiscibles dans un réseau de microcanaux. A cette échelle, le diamètre des canaux est de l'ordre de quelques dizaines de micromètres tandis que la vitesse est de l'ordre du centimètre par seconde. Cela nous permet d'utiliser les équations de Stokes incompressible pour décrire l'écoulement des fluides. Le modèle Olroyd-B est utilisé pour décrire l'écoulement du fluide viscoélastique. Afin d'effectuer des simulations numériques dans une géométrie complexe comme un réseau de microcanaux, une méthode de pénalisation est utilisée. Pour suivre l'interface entre les deux fluides, la méthode Level-Set est employée. Le modèle pour la dynamique de la ligne triple est basé sur les la loi de Cox. Enfin, on présente des résultats de simulations numériques avec des paramètres physiques réalistes.
This work is motivated by the need for better understanding the polymer Enhanced Oil Recovery (EOR) technique at the pore-scale. We consider two phase immiscible fluids in a microchannel network. In microfluidics, the diameter of the channels is of the order of a few tens of micrometers and the flow velocity is of the order of one centimeter per second. The incompressible Stokes equations are used to describe the fluid flow. The Oldroyd-B rheological model is used to capture the viscoelastic behavior. In order to perform numerical simulations in a complex geometry like a microchannel network, a penalization method is implemented. To follow the interface between the two fluids, the Level-Set method is employed. The dynamic contact line model used in this work is based on the Cox law. Finally, we perform simulations with realistic parameters.

▼ Ce mémoire présente les travaux réalisés en aérodynamique afin de pouvoir disposer d’une chaîne de conception complète nécessaire au traitement des différentes problématiques sur les pales éoliennes, qui ne peuvent être pris en compte à l’aide d’une méthode unique. Afin de pouvoir faire de l’optimisation de pales en fonction de différents critères, un outil numérique simplifié (VALDAG) a été développé. Le module de simulation utilise la méthode du Disque Actif Généralisé, qui s’appuie sur la résolution des équations Navier-Stokes, complété par des corrections empiriques. Il respecte un compromis entre la précision et le coût de calcul. Cet outil pour lequel une interface web a été développée pour le rendre adapté à des travaux d’ingénierie est susceptible de se calibrer automatiquement sur une nouvelle géométrie de pale grâce à la méthode Nelder-Mead Simplex. On peut ensuite réaliser une optimisation de la performance de la pale en modifiant cette géométrie, et générer les fichiers 3D qui serviront d’entrée à la simulation 3D et de visualisation des optimisations de forme. Ces designs optimisés sont ensuite validés par des simulations DNS à l’aide de l’outil NaSCar 3D développé à l’INRIA. Cet outil résout des équations Navier-Stokes sur un maillage cartésien 3D et prend en compte des obstacles immergés via la fonction Level-Set et la pénalisation. Après des adaptations sur le traitement de la géométrie de pales, un compromis de configuration CFD est trouvé pour simuler un rotor éolien. En conclusion, ce paquet d’outils VALDAG est peu coûteux, facile à utiliser et efficace. En associant VALDAG aux simulations 3D, une chaîne de conception est complétée.
This Ph.D. thesis presents some research work on aerodynamics of wind turbine blades, in order to dispose a conception chain necessary for different problems, which cannot be treated by one unique method. A simplified numerical toolkit (VALDAG) has been developed to optimize the performance of blades in different creteria. The simulation module use the Generalized Actuator Disc model, which relies on the solution of Navier-Stokes equations and completed with empiric corrections. This tool respects a reasonable compromise between model complexity and computational reliability. An automatic calibration mechanism was implemented using the Nelder-Mead Simplex algorithm. A web users interface (WUI) is also available to adapt VALDAG for industrial engineers. Optimization is then carried on by modifying the blades’ geometry parameters and the designs optimized is stocked in files which can be used for 3D simulation and/or visualization. The blade designed with VALDAG are then simulated by a 3D numerical tool to validate previous predictions. This 3D tool called NaSCar 3D is developed in INRIA and resolve Navier-Stokes equations on to a cartesian mesh, in which the immersed obstacles are considered with the Level-Set function and the penalization method. After some necessary adaptation for the treatment of blades’ geometry, a compromise on CFD configuration is found to…

▼ Motivée par deux problématiques liées aux plasmas de tokamak, cette thèse propose deux méthodes d'approximation numérique pour deux problèmes mathématiques s'y rattachant. D'une part, pour l'étude du transport turbulent de particules, une méthode numérique basée sur les schémas de subdivision est présentée pour la simulation de trajectoires de particules dans un champ de vitesse fortement variable. D'autre part, dans le cadre de la modélisation de l'interaction plasma-paroi, une méthode de pénalisation est proposée pour la prise en compte de conditions aux limites de type Neumann ou Robin. Analysées sur des problèmes modèles de complexité croissante, ces méthodes sont enfin appliquées dans des situations plus réalistes d'intérêt pratique dans l'étude du plasma de bord.
Motivated by two issues related to tokamak plasmas, this thesis proposes two numerical approximation methods for two mathematical problems associated with them. On the one hand, in order to study the turbulent transport of particles, a numerical method based on subdivision schemes is presented for the simulation of particle trajectories in a strongly varying velocity field. On the other hand, in the context of modeling the plasma-wall interaction, a penalization method is proposed to take into account Neumann or Robin boundary conditions. Analyzed on model problems of increasing complexity, these methods are finally applied in more realistic situations of practical interest in the study of the edge plasma.

▼ Nous étudions la convergence de systèmes dynamiques vers des équilibres. En particulier, nous nous intéressons à deux types d'équilibres. D'une part, les solutions d'inéquations variationnelles sous contraintes qui interviennent aussi dans la résolution de problèmes d'optimisation hiérarchique. D'autre part l'état stable d'un système dynamique, c'est à dire l'état où l'énergie du système est nulle. Cette thèse est divisée en deux parties principales, chacune focalisée sur la recherche d'un de ces équilibres. Dans la première partie nous étudions une classe d'algorithmes explicite-implicites pour résoudre certaines inéquations variationnelles sous contraintes. Nous introduisons un algorithme proximal-gradient pénalisé, "splitting forward-backward penalty scheme". Ensuite, nous prouvons sa convergence ergodique faible vers un équilibre dans le cas général d'un opérateur maximal monotone, et sa convergence forte vers l'unique équilibre si l'opérateur est de plus fortement monotone. Nous appliquons aussi notre algorithme pour résoudre des problèmes d'optimisation sous contrainte ou hiérarchique dont les fonctions objectif et de pénalisation sont formées d'une partie lisse et d'une autre non lisse. En effet, nous démontrons la convergence faible de l'algorithme vers un optimum hiérarchique lorsque l'opérateur est le sous-différentiel d'une fonction convexe semi-continue inférieurement et propre. Nous généralisons ainsi plusieurs algorithmes connus et nous retrouvons leurs résultats de convergence en affaiblissant les hypothèses utilisées dans nombre d'entre eux.Dans la deuxième partie, nous étudions l'action d'un contrôle interne local sur la stabilisation indirecte d'un système dynamique couplé formé de trois équations d'ondes, le système de Bresse. Sous la condition d'égalité des vitesses de propagation des ondes, nous montrons la stabilité exponentielle du système. En revanche, quand les vitesses sont différentes, nous prouvons sa stabilité polynomiale et nous établissons un nouveau taux de décroissance polynomial de l'énergie. Ceci étend des résultats présents dans la littérature au sens où le contrôle est localement distribué (et non pas appliqué à tout le domaine) et nous améliorons le taux de décroissance polynomial de l'énergie pour des conditions au bord de type Dirichlet et Dirichlet-Neumann.
We study the convergence of dynamical systems towards equilibria. In particular, we are interested in two types of equilibria. On one hand solutions of constrained variational inequations that are also involved in the resolution of hierarchical optimization problems. On the other hand the stable state of a dynamical system, i.e. the state when the energy of the system is zero. The thesis is divided into two parts, each focused on one of these equilibria. In the first part, we study a class of forward-backward algorithms for solving constrained variational inequalities. We consider a splitting forward-backward penalty scheme. We prove the weak ergodic convergence of the algorithm to an equilibrium for a general maximal…

▼ La contrefaçon est un phénomène de dimension internationale qui constitue aujourd’hui plus qu’hier un véritable fléau. Il apparaît que les principaux pays de provenance des contrefaçons saisies dans l’Union Européenne sont les pays d’Asie,notamment la Thaïlande. Cette recherche a pour but d'étudier les problèmes juridiques relatifs à la contrefaçon des droits de propriété intellectuelle. Ceci nous amène à poursuivre la recherche suivant deux axes. La première partie a pour but de mettre en évidence la comparaison de la définition de la contrefaçon en France et en Thaïlande. Elle se décompose en deux sous-parties, la première s'attachant à décrire la qualification de l’atteinte constitutive de contrefaçon selon les droits concernés (le terme « contrefaçon » en lui-même, tant en France qu’en Thaïlande, désignant différentes formes d’atteintes à un droit patrimonial de propriété intellectuelle). Pour identifier les atteintes constitutives de contrefaçon, notamment l’élément matériel, nous mettons l’accent sur 4 points: l’existence de la création, la diffusion de la création, l’usage de la création et la participation à l’action contrefaisante. S’agissant de l’élément intentionnel de contrefaçon, il semble présenter de multiples facettes. La seconde définit la preuve de la contrefaçon. On observe alors les moyens de preuve de la contrefaçon : la loi prévoit deux séries de mesures principales que nous pouvons regrouper en moyens de preuve en matière civile et pénale. Par ailleurs, il y a des moyens de preuve alternatifs entre les deux régimes. Ce sont des procédures douanières.La seconde partie a pour objet la prise en considération de la répression par les juridictions civiles et pénales. Elle se décompose donc en deux sous-parties : la première concerne les sanctions prononcées par les juridictions pénales. Nous avons déjà étudié la procédure pénale et les sanctions applicables à la contrefaçon. Il se trouve que la situation en Thaïlande est totalement différente de la situation française, notamment concernant la jurisprudence en matière pénale. Il semblerait que la majorité des décisions soient des sanctions prononcées par les juridictions pénales. La seconde sous-partie concerne quant à elle la réparation des atteintes à la propriété intellectuelle. Nous constatons que le préjudice subi, en France tout comme en Thaïlande constitue en un gain manqué . En outre l’évaluation du préjudice en France et en Thaïlande est difficile (préjudice subi en matière de marque, préjudice moral et fixation de l’indemnisation de peine privée).
Counterfeiting is an international problem. It appears that the main countries of origin of counterfeit goods seized in the European Union are the Asian countries, including Thailand. The research explains concisely the entire key factors to this whole problem. The research is divided into two parts; in the first place, I will outline pointly the definition of Intellectual Property Rights law (IPRs law) infringement between French and Thailand. Firstly, we focus on the structure of IPRs…
