This thesis explores the political struggles that followed after the appearance of irregular migrants in Sweden. The analysis starts from the assumption that the group’s precarious circumstances of living disrupted the understanding of Sweden as an inclusive society and shed light on the limits of the welfare state’s inclusionary ambitions. The overarching analytical point of entry is accordingly that the appearance of irregular migrants constitutes an opening for contestation of the demarcation of the welfare state. The analysis draws on two strands of theory to explore this opening. Citizenship theory, first, provides insights about the contradictory logics of the welfare state, i.e. the fact that it rests on norms of equality and inclusion at the same time as it is premised on a fundamental exclusion of non-members. Discourse theory, furthermore, is brought in to make sense of the potential for contestation. The study approaches these struggles over demarcation through an analysis of the debates and claims-making that took place in the Swedish parliament between 1999 and 2014. The focal point of the analysis is the efforts to make sense of and respond to the predicament of the group. The study shows that efforts to secure rights and inclusion for the group revolved around two demands. The first demand, regularisation, aimed to secure rights for irregular migrants through status, i.e. through the granting of residence permits, whereas the second demand, access to social rights, aimed to secure rights through turning the group into right-bearers in the welfare state. The thesis concludes that the debates and claims-making during the 2000s resulted in a small, but significant, shift in policy. In 2013, new legislation was adopted that granted irregular migrants access to schooling and health- and medical care. I argue that this was an effect of successful campaigning that managed to establish these particular rights as human rights, and as such, rights that should be provided to all residents regardless of legal status. Overall, however, I conclude that there has been an absence of more radical contestation of the citizenship order, and of accompanying notions of rights and entitlement, in the debates studied.

We develop the method of Fischer-Riesz equations for general boundary value problems elliptic in the sense of Douglis-Nirenberg. To this end we reduce them to a boundary problem for a (possibly overdetermined) first order system whose classical symbol has a left inverse. For such a problem there is a uniquely determined boundary value problem which is adjoint to the given one with respect to the Green formula. On using a well elaborated theory of approximation by solutions of the adjoint problem, we find the Cauchy data of solutions of our problem.

Dans les applications graphiques, les interactions avec les formes sont peu naturelles. L'utilisateur repousse autant que possible l'usage de ces applications, préférant dessiner ou sculpter une forme. Pour combler ce fossé qui se creuse entre l'informatique et le grand public, nous nous tournons vers les squelettes. Ce sont des modèles de représentation des formes intuitifs que nous proposons d'utiliser comme structure d'interaction directe et intuitive.Tous les squelettes souffrent d'un problème de qualité, que ce soit au niveau de la géométrie qu'ils capturent, de leurs quantité de bruit ou encore de l'absence d'organisation utile de leurs éléments. De plus, certaines fonctionnalités nécessaires des squelettes ne sont que partiellement résolues, et ceci grâce à des données additionnelles calculées à partir de la forme lors de la squelettisation. Ainsi, lorsque le squelette est modifié par une interaction, nous sommes dans l'incapacité de mettre à jour ces données et d'utiliser ces fonctionnalités.Nous avons construit un ensemble de solutions algorithmiques à ces problèmes. Nous faisons un usage optimal des données contenues dans le squelette pour visualiser la forme qu'il décrit, supprimer son bruit et structurer ses éléments. Nous construisons un squelette hiérarchique qui capture et contrôle toutes les zones caractéristiques d'une forme.Ce squelette est adapté pour une interaction directe et intuitive, ce qui permet de combler le fossé dont nous faisions mention. Nos travaux permettent également d'améliorer les méthodes de squelettisation et produire des squelettes qui sont déjà de bonne qualité. / The interactions in shape creation graphic applications are far from natural. The user tends to avoid as much as possible such applications and prefer to sketch or model his/her shape.To bridge this widening gap between computer and the general public, we focus on skeletons. They are intuitive shape representation models that we propose to use as direct and intuitive interaction structures.All skeletons suffer from very low quality as shape representation models, concerning the geometry of the shape they capture, the quantity of skeletal noise they contain or the lack of useful organization of their elements. Moreover, some functionalities that must be granted to skeletons are only partially solved. Those solutions make use of additional data computed thanks to the shape during the skeletonization. Thus, when the skeleton is modified by an interaction, we cannot update those data to make use of such functionalities.Thanks to a practical observation of skeletons, we built a set of algorithmic solutions to those problems.We make an optimal use of skeleton data to visualize the shape described by a skeleton, to remove skeletal noise and to structure skeleton elements. With our methods, we build the meso-skeleton, a hierarchical structure that captures and controls all characteristic parts of a shape.The meso-skeleton is adapted to be used as a direct and intuitive interaction structure, which allows us to bridge the gap aforementioned. Also, our work can lead to further researches to enhance skeletonization techniques and thus produce skeletons that are good quality shape representation models.

De par leur bonne tenue à l’impact, les matériaux composites tissés sont de bons candidats pour la conception de pièces aéronautiques. Toutefois, le manque de confiance dans les modèles se traduit par de lourdes campagnes expérimentales. L’augmentation de la part de simulation numérique et donc la réduction des coûts de certification passent par le développement d’outils permettant de dimensionner au plus juste les structures composites tissées à matrice organique (CMO) ou céramique (CMC). C’est dans ce cadre que s’inscrit cette thèse. Les formulations proposées par l’Onera a?n de décrire l’e?et de l’endommagement matriciel ont été adaptées et étendues pour prendre en compte les spéci?cités des matériaux de notre étude, en particulier la viscosité pour les CMO. Des essais sur pièces génériques ont été simulés et confrontés à l’expérience dans le but d’évaluer la pertinence des modèles développés. Ces comparaisons en partie validantes ont mis en évidence les limites des modèles dans le cadre de l’analyse de la tenue d’une structure présentant un gradient de contrainte. A?n d’améliorer les prévisions des simulations, les effets de la rupture progressive ont été pris en compte dans les formulations. Pour s’affranchir de la localisation numérique de l’endommagement, une approche originale de régularisation couplant modélisation non locale de l’endommagement et taux d’endommagement limité a été développée. Les confrontations essai/calcul ont mis en évidence l’apport d’une modélisation plus ?ne des mécanismes d’endommagement et de rupture sur l’étude de la tenue de la structure. Compte tenu des nombreuses sources d’incertitudes, quelle confiance accorder à la simulation ? Pour répondre à cette question, l’effet des incertitudes sur des quantités d’intérêts (contrainte à rupture) a été évalué. Par ailleurs, une analyse de sensibilité (décomposition de variance) a été entreprise pour l’étude de faisabilité d’une démarche de capitalisation. Dans l’optique d’une démarche d’analyse de la tolérance aux défauts, l’efficacité de notre approche à traiter diverses singularités (taille, forme) est démontrée. En?n, les limites de la modélisation macroscopique sont discutées. / Due to their high specific properties, the use of woven composite materials has become an important commercial issue in the aeronautical applications. However, the lack of confidence in classic simulation tools used for design and conception of new structures leads to huge experimental campaigns. The increase of simulations and so the decrease of certification costs requires tools development allowing a more accurate design of woven composite structures with polymer (PMC) or ceramic matrix (CMC). This present thesis is focused on that point. The current formulations are extensions of the damage approach developed at Onera to describe matrix damage. Particularly, the nonlinearity due to viscosity for PMC is taken into account. Various structural tests on generic parts has been simulated and compared to experimental results in order to evaluate the efficiency of the models. The simulations are in good agreement with the experiments except for structure with high stress gradient. In order to improve the simulations accuracy, the effect of progressive failures are introduced. To avoid the numerical problems such as damage localization or mesh sensitivity associated with the softening behavior, an original method coupling delay effect and non local approach is proposed. A good agreement between experimental and finite element calcultion results was shown. Given many uncertainties, how much can the simulation be trusted ? In order to answer this question, the influence of uncertainties on given quantities of interest (stress failure for example) has been evaluated. Moreover, a sensivity analysis has been performed for the study of an experiment capitalisation approach. In the prospect of a reliable damage tolerance analysis, the efficiency of our approach to deal with various singularities (size, form) is shown. The limits of a macroscopic modelling are ?nally discussed.

L’électroencéphalographie permet de mesurer l’activité du cerveau à partir des variations du champ électrique à la surface du crâne. Cette mesure est utilisée pour le diagnostic médical, la compréhension du fonctionnement du cerveau ou dans les systèmes d’interface cerveau-machine. De nombreux travaux se sont attachés au développement de méthodes d’analyse de ces signaux en vue d’en extraire différentes composantes d’intérêt, néanmoins leur traitement pose encore de nombreux problèmes. Cette thèse s’intéresse à la mise en place de méthodes permettant l’obtention de représentations redondantes pour ces signaux. Ces représentations se sont avérées particulièrement efficaces ces dernières années pour la description de nombreuses classes de signaux grâce à leur grande flexibilité. L’obtention de telles représentations pour les mesures EEG présente certaines difficultés du fait d’un faible rapport signal à bruit des composantes recherchées. Nous proposons dans cette thèse de les surmonter en guidant les méthodes considérées vers des représentations physiologiquement plausibles des signaux EEG à l’aide de régularisations. Ces dernières sont construites à partir de connaissances a priori sur les propriétés spatiales et temporelles de ces signaux. Pour chacune d’entre elles, des algorithmes sont proposés afin de résoudre les problèmes d’optimisation associés à l’obtention de ces représentations. L’évaluation des approches proposées sur des signaux EEG souligne l’efficacité des régularisations proposées et l’intérêt des représentations obtenues. / The electroencephalography measures the brain activity by recording variations of the electric field on the surface of the skull. This measurement is usefull in various applications like medical diagnosis, analysis of brain functionning or whithin brain-computer interfaces. Numerous studies have tried to develop methods for analyzing these signals in order to extract various components of interest, however, none of them allows to extract them with sufficient reliabilty. This thesis focuses on the development of approaches considering redundant (overcomoplete) representations for these signals. During the last years, these representations have been shown particularly efficient to describe various classes of signals due to their flexibility. Obtaining such representations for EEG presents some difficuties due to the low signal-to-noise ratio of these signals. We propose in this study to overcome them by guiding the methods considered to physiologically plausible representations thanks to well-suited regularizations. These regularizations are built from prior knowledge about the spatial and temporal properties of these signals. For each regularization, an algorithm is proposed to solve the optimization problem allowing to obtain the targeted representations. The evaluation of the proposed EEG signals approaches highlights their effectiveness in representing them.

The focus of this thesis is variational image restoration techniques that involve novel non-smooth first-order gradient regularisers: Total Variation (TV) regularisation in image and data space for reconstruction of thin structures from PET data and regularisers given by an infimal-convolution of TV and $L^p$ seminorms for denoising images with piecewise affine structures. In the first part of this thesis, we present a novel variational model for PET reconstruction. During a PET scan, we encounter two different spaces: the sinogram space that consists of all the PET data collected from the detectors and the image space where the reconstruction of the unknown density is finally obtained. Unlike most of the state of the art reconstruction methods in which an appropriate regulariser is designed in the image space only, we introduce a new variational method incorporating regularisation in image and sinogram space. In particular, the corresponding minimisation problem is formed by a total variational regularisation on both the sinogram and the image and with a suitable weighted $L^2$ fidelity term, which serves as an approximation to the Poisson noise model for PET. We establish the well-posedness of this new model for functions of Bounded Variation (BV) and perform an error analysis through the notion of the Bregman distance. We examine analytically how TV regularisation on the sinogram affects the reconstructed image especially the boundaries of objects in the image. This analysis motivates the use of a combined regularisation principally for reconstructing images with thin structures. In the second part of this thesis we propose a first-order regulariser that is a combination of the total variation and $L^p$ seminorms with $1 < p \le \infty$. A well-posedness analysis is presented and a detailed study of the one dimensional model is performed by computing exact solutions for simple functions such as the step function and a piecewise affine function, for the regulariser with $p = 2$ and $p = 1$. We derive necessary and sufficient conditions for a pair in $BV \times L^p$ to be a solution for our proposed model and determine the structure of solutions dependent on the value of $p$. In the case $p = 2$, we show that the regulariser is equivalent to the Huber-type variant of total variation regularisation. Moreover, there is a certain class of one dimensional data functions for which the regularised solutions are equivalent to high-order regularisers such as the state of the art total generalised variation (TGV) model. The key assets of our regulariser are the elimination of the staircasing effect - a well-known disadvantage of total variation regularisation - the capability of obtaining piecewise affine structures for $p = 1$ and qualitatively comparable results to TGV. In addition, our first-order $TVL^p$ regulariser is capable of preserving spike-like structures that TGV is forced to smooth. The numerical solution of the proposed first-order model is in general computationally more efficient compared to high-order approaches.

Pass-by noise testing is an important step in vehicle design and regulation compliance. Finite element analysis simulations have been used to cut costs on prototyping and testing, but the high computational cost of simulating surface vibrations from complex geometries and the resulting airborne noise propagation is making the switch to digital twin methods not viable. This paper aims at investigating the use of equivalent source methods as an alternative to the before mentioned simulations. Through the use of a simple 2D model, the difficulties such as ill-conditioning of the transfer matrix and the required regularisation techniques such as TSVD and the Tikhonov L-curve method are tested and then applied to a mesh of a 3D engine model. Source and pressure field errors are measured and their origins are explained. A heavy emphasis is put on the model geometry as a source of error. Finally, rules of thumb based on the regularisation balance and the wavelength dependent pressure sampling positions are formulated in order to achieve usable results. / Bullerprovning vid passage är ett viktigt steg i fordonsdesign och regelefterlevnad. Simuleringar med finita elementanalyser har använts för att minska kostnaderna för prototypframtagning och provning, men de höga beräkningskostnaderna för att simulera ytvibrationer från komplexa geometrier och den resulterande luftburna bullerspridningen gör att övergången till digitala tvillingmetoder inte är genomförbar. Denna uppsats syftar till att undersöka användningen av ekvivalenta källmetoder som ett alternativ till de tidigare nämnda simuleringarna. Genom att använda en enkel 2D-modell testas svårigheterna som dålig konditionering av överföringsmatrisen och de nödvändiga regulariseringsteknikerna som TSVD och Tikhonov L-kurvmetoden och tillämpas sedan på ett nät av en 3D-motormodell. Käll- och tryckfältsfel mäts och deras ursprung förklaras. Stor vikt läggs vid modellgeometrin som en felkälla. Slutligen formuleras tumregler baserade på regulariseringsbalansen och de våglängdsberoende tryckprovtagningspositionerna för att uppnå användbara resultat.

O esforço de delimitação e separação do que foi constituído enquanto propriedade privada, em oposição ao que era público, ocorreu no contexto de reformulação produtiva e do processo de inserção do país na lógica capitalista internacional, a partir de meados do século XIX. Como consequência deste processo, tanto a propriedade privada quanto a propriedade pública foram estabelecidas simultaneamente. Na prática, a informalidade da situação fundiária das terras públicas no Brasil interferiu na ocupação do território e incentivou inúmeros conflitos fundiários urbanos e rurais. A apropriação ilegal e indevida de extensas frações de áreas públicas da União por particulares, por meio do jogo da legalização e falsa legalização, se deu em função do tratamento displicente dado à gestão do Patrimônio da União, marcado pela dificuldade do Estado em regular e controlar de fato o acesso à terra e aos recursos naturais e pelo desconhecimento sobre a abrangência do domínio público. A partir de 2003, o órgão responsável pela gestão do patrimônio da União no Brasil adotou diversas mudanças administrativas e legais, ao rever o papel de propriedade da União como \"patrimônio de todo brasileiro\", visando a função social da propriedade pública e a inversão da lógica histórica marcada pela centralização de decisões, perspectiva meramente arrecadatória e de gestão cartorial dos bens públicos. Em decorrência dessas mudanças, depois de dez anos, estima-se que cerca de 560 mil famílias poderiam ter sido beneficiadas por ações de regularização fundiária de assentamentos urbanos em imóveis da União, não fossem os bloqueios enfrentados para a efetivação dessas ações. Apesar dos avanços conquistados, especialmente, no campo do reconhecimento de direitos, estes não foram suficientes para promover uma significativa inflexão na lógica de gestão de terras da União. Aspectos relacionados à cultura política, jurídica e administrativa, na esfera local e federal, permeados por questões urbanísticas, impediram mudanças mais significativas no cumprimento da função social da propriedade pública da União. O território que abrange as margens do Canal de Santos, no litoral de São Paulo, onde está o Porto de Santos, considerando sua localização estratégica, foi escolhido para investigar como são estabelecidas as disputas e as soluções propostas pela SPU, em torno dos múltiplos interesses que recaem sobre a utilização de terras da União, a partir da análise dos casos da Ilha de Bagres e do Sítio Conceiçãozinha. / The delimiting and separating effort of what would be constituted as private property, in opposition to what was state-owned, occurred from the middle of the nineteenth century, in the context of the Brazilian state\'s process of insertion into the international capitalist logic and its related productive process transformation. As a result of this process, private property and the public property were established simultaneously. In reality, the informality of the public land tenure in Brazil interfered in the occupation of the territory, and encouraged countless urban and rural land conflicts. And yet, throughout Brazilian history, the lenient treatment given to the management of the national heritage benefited an illegal and improper appropriation of large fractions of national public areas by individuals using the \"legalisation and false legalisation\" game. This management of the national heritage is characterised by total ignorance of public dominance and the difficulty of the State to regulate and truly control the access to land and natural resources. Since 2003, the management of the national heritage in Brazil has adopted a number of administrative and legal changes by revising the state ownership role as \"heritage of every Brazilian\", aiming the social function of public property and reversing the historical logic of centralisation of decisions, a perspective reduced to revenue collection and the management of the legalities of public property. After ten years, as a result of these changes, if the execution of these actions had not been blocked, it is estimated that almost 560.000 families would have benefited by land regularisation actions of urban settlements in the real estate of the Union. Regarding to the recognition of rights, despite the advances, such changes were not sufficient to promote a significant shift to the national lands management logic. That is because aspects related to political, legal and administrative cultures permeated by urbanistic issues, has prevented more changes in the fulfilment of the social function of the national land. The territory that covers the banks of the Santos Canal, where the Port of Santos is located on the coast of São Paulo State, was chosen because of its strategic location to investigate how disputes and solutions proposed by the SPU, which is based on the multiple interests of the uses of National Lands, are established. The investigation analysed the cases of Ilha de Bagres and Sítio Conceiçãozinha.

Une forte redondance des variables explicatives cause de gros problèmes d'identifiabilité et d'instabilité des coefficients dans les modèles de régression. Même lorsque l'estimation est possible, l'interprétation des résultats est donc extrêmement délicate. Il est alors indispensable de combiner à leur vraisemblance un critère supplémentaire qui régularise l'estimateur. Dans le sillage de la régression PLS, la stratégie de régularisation que nous considérons dans cette thèse est fondée sur l'extraction de composantes supervisées. Contraintes à l'orthogonalité entre elles, ces composantes doivent non seulement capturer l'information structurelle des variables explicatives, mais aussi prédire autant que possible les variables réponses, qui peuvent être de types divers (continues ou discrètes, quantitatives, ordinales ou nominales). La régression sur composantes supervisées a été développée pour les GLMs multivariés, mais n'a jusqu'alors concerné que des modèles à observations indépendantes.Or dans de nombreuses situations, les observations sont groupées. Nous proposons une extension de la méthode aux GLMMs multivariés, pour lesquels les corrélations intra-groupes sont modélisées au moyen d'effets aléatoires. À chaque étape de l'algorithme de Schall permettant l'estimation du GLMM, nous procédons à la régularisation du modèle par l'extraction de composantes maximisant un compromis entre qualité d'ajustement et pertinence structurelle. Comparé à la régularisation par pénalisation de type ridge ou LASSO, nous montrons sur données simulées que notre méthode non seulement permet de révéler les dimensions explicatives les plus importantes pour l'ensemble des réponses, mais fournit souvent une meilleure prédiction. La méthode est aussi évaluée sur données réelles.Nous développons enfin des méthodes de régularisation dans le contexte spécifique des données de panel (impliquant des mesures répétées sur différents individus aux mêmes dates). Deux effets aléatoires sont introduits : le premier modélise la dépendance des mesures relatives à un même individu, tandis que le second modélise un effet propre au temps (possédant donc une certaine inertie) partagé par tous les individus. Pour des réponses Gaussiennes, nous proposons d'abord un algorithme EM pour maximiser la vraisemblance du modèle pénalisée par la norme L2 des coefficients de régression. Puis nous proposons une alternative consistant à donner une prime aux directions les plus "fortes" de l'ensemble des prédicteurs. Une extension de ces approches est également proposée pour des données non-Gaussiennes, et des tests comparatifs sont effectués sur données Poissonniennes. / High redundancy of explanatory variables results in identification troubles and a severe lack of stability of regression model estimates. Even when estimation is possible, a consequence is the near-impossibility to interpret the results. It is then necessary to combine its likelihood with an extra-criterion regularising the estimates. In the wake of PLS regression, the regularising strategy considered in this thesis is based on extracting supervised components. Such orthogonal components must not only capture the structural information of the explanatory variables, but also predict as well as possible the response variables, which can be of various types (continuous or discrete, quantitative, ordinal or nominal). Regression on supervised components was developed for multivariate GLMs, but so far concerned models with independent observations.However, in many situations, the observations are grouped. We propose an extension of the method to multivariate GLMMs, in which within-group correlations are modelled with random effects. At each step of Schall's algorithm for GLMM estimation, we regularise the model by extracting components that maximise a trade-off between goodness-of-fit and structural relevance. Compared to penalty-based regularisation methods such as ridge or LASSO, we show on simulated data that our method not only reveals the important explanatory dimensions for all responses, but often gives a better prediction too. The method is also assessed on real data.We finally develop regularisation methods in the specific context of panel data (involving repeated measures on several individuals at the same time-points). Two random effects are introduced: the first one models the dependence of measures related to the same individual, while the second one models a time-specific effect (thus having a certain inertia) shared by all the individuals. For Gaussian responses, we first propose an EM algorithm to maximise the likelihood penalised by the L2-norm of the regression coefficients. Then, we propose an alternative which rather gives a bonus to the "strongest" directions in the explanatory subspace. An extension of these approaches is also proposed for non-Gaussian data, and comparative tests are carried out on Poisson data.
