▼ La reconstruction tomographique à partir
de données
de projections est un problème inverse largement utilisé en imagerie médicale et
de façon plus modeste pour le contrôle nondestructif. Avec un nombre suffisant
de projections, les algorithmes analytiques permettentdes reconstructions rapides et précises. Toutefois, dans le cas d’un faible nombre
de vues(imagerie faible dose) et/ou d’angle limité (contraintes spécifiques liées à l’installation), lesdonnées disponibles pour l’inversion ne sont pas complètes, le mauvais conditionnementdu problème s’accentue, et les résultats montrent des artefacts importants. Pour aborderces situations, une approche alternative consiste à discrétiser le problème
de reconstruction,et à utiliser des algorithmes itératifs ou une formulation statistique du problème afinde calculer une estimation
de l’objet inconnu. Ces méthodes sont classiquement basées surune discrétisation du volume en un ensemble
de voxels, et fournissent des cartes 3D
de ladensité
de l’objet étudié. Les temps
de calcul et la ressource mémoire
de ces méthodesitératives sont leurs principaux points faibles. Par ailleurs, quelle que soit l’application, lesvolumes sont ensuite segmentés pour une analyse quantitative. Devant le large éventaild’outils
de segmentation existant, basés sur différentes interprétations des contours et defonctionnelles à minimiser, les choix sont multiples et les résultats en dépendent.Ce travail
de thèse présente une nouvelle approche
de reconstruction simultanée àla segmentation des différents matériaux qui composent le volume. Le processus dereconstruction n’est plus basé sur une grille régulière
de pixels (resp. voxels), mais sur unmaillage composé
de triangles (resp. tétraèdres) non réguliers qui s’adaptent à la formede l’objet. Après une phase d’initialisation, la mé
thode se décompose en trois étapesprincipales que sont la reconstruction, la segmentation et l’adaptation du maillage, quialternent
de façon itérative jusqu’à convergence. Des algorithmes itératifs
de reconstructioncommunément utilisés avec une représentation conventionnelle
de l’image ont étéadaptés et optimisés pour être exécutés sur des grilles irrégulières composées d’élémentstriangulaires ou tétraédriques. Pour l’étape
de segmentation, deux méthodes basées surune approche paramétrique (snake) et l’autre sur une approche géométrique (level
set)ont été mises en oeuvre afin
de considérer des objets
de différentes natures (mono- etmulti- matériaux). L’adaptation du maillage au contenu
de l’image estimée est basée surles contours segmentés précédemment, pour affiner la maille au niveau des détails del’objet et la rendre plus grossière dans les zones contenant peu d’information. En finde processus, le résultat est une image classique
de reconstruction tomographique enniveaux
de gris, mais dont la représentation par un maillage adapté au contenu proposeidirectement une segmentation associée. Les résultats montrent que la partie adaptative dela mé

▼ The objective of this research is to study practical generalization of domination in graphs and explore the theoretical and computational aspects of models arising in the design of wireless networks. For the construction of a virtual backbone of a wireless ad-hoc network, two different models are proposed concerning reliability and robustness. This dissertation also considers wireless sensor placement problems with various additional constraints that reflect different real-life scenarios.
In wireless ad-hoc network, a connected dominating
set (CDS) can be used to serve as a virtual backbone, facilitating communication among the members in the network. Most literature focuses on creating the smallest virtual backbone without considering the distance that a message has to travel from a source until it reaches its desired destination. However, recent research shows that the chance of loss of a message in transmission increases as the distance that the message has to travel increases. We propose CDS with bounded diameter, called dominating s-club (DsC) for s ? 1, to model a reliable virtual backbone.
An ideal virtual backbone should retain its structure after the failure of a certain number of vertices. The issue of robustness under vertex failure is considered by studying k-connected
m-dominating
set. We describe several structural properties that hold form ? k, but fail when
m < k. Three different formulations based on vertex-cut inequalities are shown depending on the value of k and
m. The computational results show that the proposed lazy-constraint approach compares favorably with existing methods for the minimum connected dominating
set problem (for k =
m = 1). The experimental results for k =
m = 2, 3, 4 are presented as well.
In the wireless sensor placement problem, the objective is often to place a minimum number of sensors while monitoring all sites of interest, and this can be modeled by dominating
set. In some practical situations, however, there could be a location where a sensor cannot be placed because of environmental restrictions. Motivated by these practical scenarios, we introduce varieties of dominating
set and the corresponding optimization problems. For these new problems, we consider the computational complexity, mathematical programming formulation, and analytical bounds on the size of structures of interest. We solve these problems using a general commercial solver and compare its performance with that of simulated annealing.

▼ Les transistors monoélectroniques (
SET : Single Electron Transistor ) sont des dispositifs
similaires aux transistors FET (Field Effect Transistor ) conventionnels. Ce qui distingue
le
SET d'un transistor FET est la présence d'un îlot ou boîte quantique séparée par une
couche d'isolant entre la source et le drain. Cette particularité rend le transistor mono-
électronique très sensible aux variations
de potentiel dans son environnement et en fait
un des détecteurs
de charge les plus sensibles qui existe. Historiquement, ces dispositifs
étaient considérés comme des candidats potentiels pour remplacer les transistors conventionnels
en raison
de leur faible consommation énergétique et leurs petites dimensions.
Cependant, aujourd'hui, les progrès énormes
de l'industrie ont amélioré les performances
des transistors FET à un point où les avantages des
SET sont marginales. Néanmoins, la
recherche continue
de s'effectuer sur ce type
de dispositif, non plus avec la prétention
de
remplacer l'électronique moderne, mais avec la perspective d'être utilisé dans des applications
quantiques et en recherche scientifique et
de complémenter la technologie CMOS
par l'intégration 3D
de dispositifs sous forme
de capteur ultra-sensible.
Dans cette perspective, le procédé
de fabrication doit donc être compatible avec les techniques
de fabrication utilisées en industrie afin
de faciliter le transfert technologique vers
l'industrie
de la microélectronique. Cependant, les travaux sur les
SET compatibles avec
les procédé utilisé dans le BEOL (Back end of line ) des techniques industrielles n'ont
jamais démontré
de fonctionnement à température ambiante. Les résultats
de cette maî-
trise montrent qu'il est possible d'augmenter la température d'opération d'un détecteur
de
charge basé sur un transistor monoélectronique tout en respectant les contraintes imposé
par les procédés industrielles. Cette démonstration est effectuée avec des simulations
de
dispositifs par élément aini ainsi que par des validation expérimentale
de la faisabilité du
procédé
de fabrication.
La fabrication et la caractérisation électrique
de SET ont permis
de valider la reproductibilit
é du procédé
de fabrication du prédécesseur, Gabriel Droulers. Un dispositif composé
de deux transistors monoélectroniques couplé par l'îlot est utilisé afin
de simuler la détection
de charge avec un fonctionnement théorique à la température
de l'azote liquide (77
K). Le développement et la caractérisation
de procédés
de déposition par couche atomique
ALD (Atomic Layer Deposition ) ont été effectués pour atteindre cet objectif. Finalement,
chaque étape du procédé
de fabrication a été caractérisée et validée indépendamment.

▼ Ces dernières années, les techniques d'imagerie ont fait l'objet de beaucoup d'améliorations. Elles permettent de fournir des images numériques 2D ou 3D précises de zones parfois invisibles à l’œil nu. Ces techniques s'appliquent dans de nombreux domaines comme l'industrie cinématographique, la photographie ou l'imagerie médicale... Dans cette thèse, l'imagerie sera utilisée pour effectuer des simulations numériques en la couplant avec un solveur éléments finis. Nous présenterons, en premier lieu, la morphologie mathématique et la méthode d'immersion d'image. Elles permettront l'extraction d'informations permettant la transformation d'une image dans un maillage exploitable. Puis, une méthode itérative d'adaptation de maillage basée sur un estimateur d'erreur sera utilisée afin de construire un maillage optimal. Ainsi, un maillage sera construit uniquement avec les données d'une image. Nous proposerons également une nouvelle méthodologie pour construire une fonction régulière a l'aide d'une méthode de réinitialisation de la distance signée. Deux avantages sont à noter : l'utilisation de la fonction régularisée permet une bonne adaptation de maillage. De plus, elle est directement utilisable par le solveur éléments finis. Les simulations numériques sont donc réalisées en couplant éléments finis stabilisés, adaptation de maillage anisotrope et réinitialisation. L'objectif de cette thèse est donc de simplifier le calcul numérique à partir d'image, d'améliorer la précision numérique, la construction d'un maillage automatique et de réaliser des calculs numériques parallèles efficaces. Les applications envisagées peuvent être dans le domaine médical, de la physique des matériaux ou du design industriel.
Imaging techniques have well improved in the last decades. They may accurately provide numerical descriptions from 2D or 3D images, opening perspectives towards inner information, not seen otherwise, with applications in different fields, like medicine studies, material science or urban environments. In this work, a technique to build a numerical description under the mesh format has been implemented and used in numerical simulations when coupled to finite element solvers. Firstly, mathematical morphology techniques have been introduced to handle image information, providing the specific features of interest for the simulation. The immersed image method was then proposed to interpolate the image information on a mesh. Then, an iterative anisotropic mesh adaptation operator was developed to construct the optimal mesh, based on the estimated error concerning the image interpolation. The mesh is thus directly constructed from the image information. We have also proposed a new methodology to build a regularized phase function, corresponding to the objects we wish to distinguish from the image, using a redistancing method. Two main advantages of having such function are: the gradient of the regularized function performs better for mesh adaptation; the regularized function may be directly used for the finite element solver.…

MATHEMATICAL PLURALISM AND SOME GENERIC ABSOLUTENESS RESULTS IN SET THEORY: A PHILOSOPHICAL INQUIRY.

▼ The forcing technique was discovered by Paul Cohen in the early sixties. Since then forcing has appeared to be a very powerful tool to provide independence results in
Set theory. Actually, because of the foundational role played by
Set theory with regard to the rest of classical mathematics, and because of the possibility to mimic from the standard axiomatic basis of
Set theory, ZFC, the proof of the existence of almost any mathematical object, forcing has been applied to different areas of mathematics revealing to us the undecidability of many different important questions connected with different branches of mathematics.
Given the pervasive presence of the independence phenomenon in
Set theory determined by forcing, a natural philosophical question arises: is forcing the ultimate horizon of
Set theory, or is it (as a source of undecidability) to be considered as a pathology that needs to be neutralised? A special kind of results in
Set theory, known in literature as generic absoluteness results, give mathematical substance to the perspective that the real challenge that the discovery of the forcing technique places to the
set theorist, as well as to the philosopher of mathematics, goes beyond the idea that the right answer to questions such as the Continuum Hypothesis is given by computing the precise extent of their undecidability. In fact, when it is possible to relieve generic absoluteness for a certain mathematical structure, a different framework appears where forcing can be exploited and, so we may say, integrated into the practice of the mathematician as a strong tool for proving theorems. In chapter 1 of my dissertation I recall some main aspects of the forcing technique developed following the Boolean valued-models approach introduced by Scott, Solovay, and Vopenka starting from 1965. In chapters 2 and 3 I analyze some main motivations behind Viale's and Woodin's alternative strategies for producing generic absoluteness for the structure at the level of the Continuum problem. I try to stress, in particular, the essential use of the so-called forcing axioms that is inherent Viale's generic absoluteness results and that, to some extent, conflicts with Woodin's choice to introduce a strong logic as the appropriate setting for studying the possibility of generic absoluteness at the level of the Continuum problem. In chapter 4 I open the philosophical discussion and I try to correlate the pure mathematical phenomenon of generic absoluteness described in chapters 2 and 3 to the more general philosophical debate concerning the question of Pluralism in
Set theory and the search for new axioms. Insofar as we are interested in spell out Viale's and Woodin's absoluteness results in terms of the right axiomatisation for the structure theory where the Continuum problem is expressible, I try to sketch an argument according to which the possibility to unify the two distinct theories offered by Viale and Woodin emerges as one of notable philosophical importance.

▼ String musicians can experience pain while playing their instruments. In fact, research indicates that the majority of string musicians suffer from constant pain and musculoskeletal disorder. This can happen to all string musicians, from beginner students through professionals. Therefore, a review of literature was needed to help teachers to better understand the musculoskeletal system of a growing student and how to provide instruction so that pain and injury can be avoided. Research suggests that musicians should see a physical therapist, physician, and/or a chiropractor to prevent pain and musculoskeletal disorder. Adding exercises such as weight training, cardio conditioning, yoga, and stretching on a regular basis will help prevent overuse of muscles. In children, the musculoskeletal system is continuously growing and teachers need to ensure the students are sized correctly and are shown the proper set-up for their instrument. Proper set-up throughout a students' growing period along with exercising and stretching before, during, and after practice and rehearsals can help students avoid injuries during their school and/or continued music career.

▼ We consider the problem of identifying the threshold at which a one-dimensional regression function leaves its baseline value. This is motivated by applications from dose-response studies and environmental statistics. We develop a novel approach that relies on the dichotomous behavior of p-value statistics around this threshold. We study the asymptotic behavior of our estimate in two different sampling settings for constructing confidence intervals.
The multi-dimensional version of the threshold estimation problem has connections to fMRI studies, edge detection and image processing. Here, interest centers on estimating a region (equivalently, its complement) where a function is at its baseline level. In certain applications, this
set corresponds to the background of an image; hence, identifying this region from noisy observations is equivalent to reconstructing the image. We study the computational and theoretical aspects of an extension of the p-value procedure to this setting, primarily under a convex shape-constraint in two dimensions, and explore its applicability to other situations as well.
Multistage procedures, obtained by splitting the sampling budget across stages, and designing the sampling at a particular stage based on information obtained from previous stages, are often advantageous as they typically accelerate the rate of convergence of the estimates, relative to one-stage procedures. The step-by-step process, though, induces dependence across stages and complicates the analysis in such problems. We develop a generic framework for
M-estimation in a multistage setting and apply empirical process techniques to describe the asymptotic behavior of the resulting
M-estimates. Applications to change-point estimation, inverse isotonic regression and mode estimation are provided.
In a departure from the more statistical components of the dissertation, we consider a central limit question for linear random fields. Random fields – real valued stochastic processes indexed by a multi-dimensional
set – arise naturally in spatial data analysis and thus, have received considerable interest. We prove a Central Limit Theorem (CLT) for linear random fields that allows sums to be taken over sets as general as the disjoint union of rectangles. A simple version of our result provides a complete analogue of a CLT for linear processes with no extra assumptions.

▼ Les séquences binaires pseudo-aléatoires sont couramment employées par les systèmes
de transmissions numériques ou des mécanismes
de chiffrement. On les retrouve en particulier dans les transmissions par étalement
de spectre par séquence direct (e.g. 3G ou GPS)) ou pour construire des séquences d'apprentissage pour faciliter la synchronisation ou l'estimation du canal (e.g. LTE). Un point commun à toutes ces applications est la nécessité
de se synchroniser avec la séquence émise. La mé
thode conventionnelle consiste à générer la même séquence au niveau du récepteur et la corréler avec le signal reçu. Si le résultat dépasse un seuil pré-défini, la synchronisation est déclarée acquise. On parle alors
de détection par corrélation.Cette thèse aborde une autre voie : la détection des séquences binaires pseudo-aléatoire par des techniques
de décodage canal. Ceci permet par exemple
de détecter des séquences longues (e.g.
de période 242), contrairement aux techniques par corrélation qui sont trop complexes à implémenter. Cela nécessite néanmoins que le récepteur connaisse au préalable le polynôme générateur
de la séquence.Nous avons montré que le décodage d'une séquence pseudo-aléatoire est une problématique du type 'détecte et décode'. Le récepteur détecte la présence
de la séquence et simultanément estime son état initial. Ceci correspond dans la théorie classique
de la détection à un détecteur
de type GLRT qui ne connaît pas la séquence émise, mais qui connaît sa mé
thode de construction. L'algorithme implémente alors un GLRT qui utilise un décodeur pour estimer la séquence reçue. Ce dernier est implémenté avec un algorithme
de décodage par passage
de messages qui utilise une matrice
de parité particulière. Elle est construite avec des équations
de parités différentes, chacune ayant un poids
de Hamming valant t.Il correspond au nombre
de variables participants à l'équation.Les équations
de parité sont un constituant indispensable du décodeur. Nous avons donné leur nombre pour les
m-séquences et les séquences
de Gold. Pour le cas particulier des séquences
de Gold, nous avons calculé le nombre d'équations
de parité
de poids t=5 lorsque le degré du polynôme générateur r est impair. Ce calcul est important car il n'y a pas d'équations
de parité
de poids t < 5 lorsque r est impair. Le nombre d'équations
de parité est aussi utilisé pour estimer le degré minimal des équations d'un poids t donné. Nous avons montré que le modèle
de prédiction estime correctement la valeur moyenne du degré minimal
de l'ensemble des séquences
de Gold. Nous avons néanmoins mis en évidence une grande variabilité du degré minimal des séquences autour
de cette valeur moyenne.Nous avons ensuite identifié les ensembles absorbants complets
de plus petite taille lorsque le décodeur emploie plusieurs polynômes
de parité. Ces ensembles bloquent la convergence du décodeur lorsque celui-ci est alimenté avec du bruit. Ceci évite les fausses alarmes lors du processus
de détection. Nous avons montré que des cycles 'transverses' détruisent ces ensembles absorbants,…

▼ Acquisitions are a major part of the growth and evolution of companies within varying markets. They are conducted under various circumstances with differing aims and rationales, and for different purposes. This thesis focuses on acquisitions carried out by serial investors acting in a private equity market. These acquisitions are characterised by a highly competitive nature, where access to a large pipeline of potential targets is believed to be a key success factor. As such, deal origination and sourcing of potential targets become important factors to facilitate a high-paced deal flow. Earlier research suggests that this is well researched with regards to venture capital, but to a large extent lacking within private equity. This thesis analyses and discusses the possibility of systematising early evaluation of potential acquisition targets within private equity. The aim is to suggest a framework that may be utilised, consisting of the criteria deemed important for early evaluation. Through utilising multi criteria decision making, the framework allows for a relative importance between criteria to contribute to assessment, while fuzzy set theory allows for a degree of uncertainty to be incorporated. This thesis is conducted through data collection from a number of professionals within private equity, selected from a non-probability sample. Semi-structured interviews and a 3 pairwise comparison is utilised to allow for analysis and discussion with regards to earlier research and theory, while allowing for comparison between respondents. The results of the thesis indicate that utilising a framework for early evaluation of potential targets may be beneficial. The key dimensions to consider are financial, commercial and market capabilities. However, the criteria constituting the dimensions may be firm or industry specific.
Förvärv är en viktig del av tillväxten och utvecklingen av företag i en rad olika marknader. De genomförs under varierande förutsättningar med olika mål och avsikter, och med olika syften. Denna uppsats fokuserar på förvärv utförda av serieinvesterare på en riskkapitalsmarknad. Dessa förvärv karaktäriseras av en konkurrensutsatt marknad, där tillgång till en bred pipeline av potentiella förvärvsmöjligheter förväntas vara en viktig framgångsfaktor. Således är hantering av leadsgenerering och sourcing av möjliga förvärvsobjekt viktiga faktorer för att främja ett aktivt förvärvsflöde. Tidigare forskning tyder på att detta är ett välutforskat område inom venture capital, men saknas i stor utsträckning inom riskkapital. Denna uppsats analyserar och diskuterar möjligheten att systematisera tidig utvärdering av potentiella förvärvsobjekt inom riskkapital. Avsikten är att föreslå ett ramverk som kan användas, bestående av de kriteria som anses viktiga vid tidig utvärdering. Genom att använda multi criteria decision making möjliggör ramverket en relativ betydelse mellan kriterier att påverka bedömningen, medan fuzzy set-teori möjliggör för en grad av osäkerhet att…

▼ Background and Purpose: stroke is a very important cause of mortality and disability. This
study has the objective to identify predictors factors and the clinical consequences of
nosocomial infection in acute stroke.
Patients and Methods: we prospectively identified a consecutive cohort of patients who we
either admitted after an acute stroke. We used predefined diagnostic criteria by OMS and SEN
for stroke and by CDC and SEIMC for infection.
Results: 258 patients with acute stroke were included. 102 (39,5%) had at least one nosocomial
infection (45,5%
M; edad X 78,2
DE 9,7). The mean hospital stay was 14,9 days (8,4) in
infection patients and 8,4 days (5,6) in no infection patients (p<0,001). 31 patients died and 22
(71%) had at least one cause of infection. Using logistic regression analysis, the dysphagia (OR
12,7; IC 95% 5,3-30,1; p<0,001) is the strongest and independient predictor of nosocomial
infection. Others factors are crural motor affectation (OR 4,5; IC 95% 1,7-12,3; p=0,003),
urinary incontinence (OR 2,9; IC 95% 1,3-6,4; p=0,009) and diabetes mellitus (OR 2,3; IC 95%
1,1-4,7; p=0,03). Baseline imbalance NIHSS >20 during the admission (OR 17,3; IC 95% 5,1-
59,5; p<0,001), mas effect diagnosticated on TAC (OR 4,4; IC 95% 1,4-14; p=0,012), poor
outcome neurological during the first day (OR 11,6; IC 95% 3,6-37,2; p<0,001), chest infection
(OR 5,7; IC 95% 1,8-18,3; p=0,003) and the hyperglucemia in admission (OR 6; IC 95% 1,5-
25,6; p=0,015), are the independients predictors factors that increasing the likelihood for
mortality in acute stroke. Baseline imbalance NIHSS >20 (OR 8,9; IC 95% 2,7-29; p<0,001),
poor outcome neurological during the first day (OR 8,1; IC 95% 2,2-29,6%; p=0,002) and the
urinary incontinence (OR 10,1; IC 95% 5-20,6; p<0,001) are the independients predictors
factors that increasing the likelihood of poor functional state in discharge.
Conclusions: dysphagia, crural motor affectation, urinary incontinence and diabetes mellitus
are the independients predictors factors that increasing the likelihood for nosocomial infection
in acute stroke. The chest infection increase significantly the likelihood of mortality during the
hospital stay.

▼ L'algorithme FastICA est l'un des algorithmes les plus populaires dans le domaine de l'analyse en composantes indépendantes (ICA). Il existe deux versions de FastICA: Celle qui correspond au cas où l'échantillon est de taille infinie, et celle qui traite de la situation concrète, où seul un échantillon de taille finie est disponible. Dans cette thèse, nous avons fait une étude détaillée des vitesses de convergence de l'algorithme FastICA dans le cas où la taille de l'échantillon est finie ou infinie, et nous avons établi cinq critères pour le choix des fonctions de non-linéarité. Dans les trois premiers chapitres, nous avons introduit le problème de l'ICA et revisité les résultats existants. Dans le Chapitre 4, nous avons étudié la convergence du FastICA empirique et le lien entre la limite de FastICA empirique et les points critiques de la fonction de contraste empirique. Dans le Chapitre 5, nous avons utilisé la technique du M-estimateur pour obtenir la normalité asymptotique et la matrice de covariance asymptotique de l'estimateur FastICA. Ceci nous a permis aussi de déduire quatre critères pour choisir les fonctions de non-linéarité. Un cinquième critère de choix de non-linéarité a été étudié dans le chapitre 6. Ce critère est basé sur une étude fine de la vitesse de convergence de FastICA empirique. Nous avons illustré chaque chapitre par des résultats numériques qui valident nos résultats théoriques.
The FastICA algorithm is one of the most popular algorithms in the domain of Independent Component Analysis (ICA). There exist two versions of FastICA: the one that corresponds to the ideal case that the sample size is infinite, and the one that deal with the practical situation, where a sample of finite size is available. In this thesis, we made a detailed study of the rate of convergence of the FastICA algorithm of both versions, and we established five criteria for the choice of the non-linearity function. In the first three chapters, we introduced the problem of ICA and revisited the classical results. In Chapitre 4, we studied the convergence of empirical FastICA and the link between the limit of empirical FastICA and the critical points of the empirical contrast function. In Chapter 5, we used the technique of M-estimator to obtain the asymptotic normality and the asymptotic covariance matrix of the FastICA estimator. This allowed us to derive four criteria to choose the non-linearity function. A fifth criterion for the choice of the non-linearity function was studied in Chapter 6. This criterion is based on the rate of convergence of the empirical FastICA algorithm. At the end of each chapter, we provided numerical simulations that validate our theoretical results.

▼ O presente trabalho tem como objetivo aplicar uma nova sistemática de abastecimento de peças ao longo de uma linha de montagem de uma empresa automobilística. Esta empresa está localizada no Vale do Paraíba, na cidade de São Jose dos Campos. Partindo-se do princípio da manufatura enxuta, onde se busca eliminar os desperdícios dentro do ciclo de trabalho do operador, identificou-se a oportunidade de aplicar o conceito de Set Part System como uma ferramenta importante no processo para tornar o ciclo de produção do operador mais enxuto. A avaliação realizada no processo demonstrou que houve ganhos significativos em produtividade e qualidade nos produtos montados. O objetivo principal foi demonstrar como a aplicação desta ferramenta pode favorecer o processo de melhoria contínua, fazendo com que o nível de decisão do operador fosse realizado em uma etapa anterior, desta forma o operador no ato da montagem somente realiza a tarefa de montagem. Dentro de um cenário cada vez mais competitivo globalmente, é necessário buscar a redução de custos de produção, melhorar a qualidade e tornar cada vez mais enxuto o processo de montagem de uma linha de produção. A indústria automobilística sempre vista como exemplo incansável na busca pela manufatura enxuta, mais uma vez serve como exemplo em um sistema de abastecimento simples que traz um grande retorno.
This study aimed to implement a new system of supply of parts along an assembly line of a car company. This company is located in the Paraíba Valley, in the city of Sao Jose dos Campos. Starting from the principle of lean manufacturing, which seeks to eliminate waste in the production process of the operator. We identified the opportunity to apply the concept of Set Part System as an important tool in the process to make the cycle operator leaner. The evaluation process showed that there were significant gains in productivity and quality in products assembled. The main objective was to demonstrate the application of this tool can help the process of continuous improvement, making the decision level of operator was carried out in a previous step, so the operator at the time of installation only accomplishes the task. Within an increasingly more competitive globally, it is necessary to seek a reduction of production costs, improving quality and becoming leaner assembly process of a production line. The automotive industry always seen as an example in the relentless pursuit of lean manufacturing, once again serves as an example in a simple supply system that brings a great return.

▼ A otimização topológica de estruturas está relacionada à concepção de projetos que executem suas funções com nível de segurança adequado empregando a quantidade mínima de material. Neste trabalho, determina-se a geometria ótima de estruturas planas por meio do acoplamento do Método dos Elementos de Contorno (MEC) ao Método Level Set (MLS). O algoritmo é composto por 3 etapas: problema mecânico, otimização topológica e reconstrução da estrutura. O problema mecânico é resolvido pelas equações algébricas do MEC. A otimização topológica é determinada pelo MLS, este representa a geometria do corpo e suas evoluções por meio da função Level Set (LS) avaliada em seu nível zero. Na reconstrução realiza-se o remalhamento, pois a cada iteração a estrutura é modificada. O acoplamento proposto resulta na geometria ótima da estrutura sem a necessidade da aplicação de filtros. Os exemplos analisados mostram que algoritmo desenvolvido capta adequadamente a geometria ótima das estruturas. Com esse trabalho, avança-se no campo das aplicações do acoplamento MEC-MLS e no desenvolvimento de soluções inovadoras para problemas complexos de engenharia.
In general, the topological optimization of structures is related to design projects that perform their functions with appropriate security levels using the minimum amount of material. This research determines the optimal geometry of 2D structures by coupling the Boundary Blement Method (BEM) to Level Set Method (LSM). The algorithm consists of 3 steps: mechanical model, topology optimization and structure reconstruction. The mechanical model is solved by BEM algebraic equations. The topology optimization is determined using the MLS, the geometry of the body is determined by the Level Set (LS) function evaluated at the zero level. The reconstruction achieves the remeshing, because for each iteration of the structure is modified. The proposed coupling results in the optimal geometry of the structure without the filters application. The examples show that the algorithm developed captures adequately the optimal geometry of the structures. With this dissertation, it is possible advance in the field of applications of the BEM - LSM and develop innovative solutions to complex engineering problems.

▼ Le procédé de fabrication par RTM (Resin Transfer Molding) a été étudié numériquement à l’aide de la méthode XFEM (eXtended Finite Element Method) combinée avec la méthode Level set. La méthode XFEM permet d’obtenir une bonne précision numérique de la pression près du front d’écoulement, où son gradient est discontinu. Les fonctions de forme enrichies de la méthode XFEM sont proposées à l’aide des valeurs de Level set en vue de décrire correctement l’interpolation avec le front d’écoulement. En plus, la méthode de Level set est utilisée pour transporter le front d’écoulement à chaque pas de temps durant le remplissage du moule. Les valeurs de Level set sont calculées à l’aide d’une méthode de Galerkin implicite. Le solveur multi-frontal d’IPSAP a été utilisé pour la résolution du système. Cette étude a été validée en comparaison avec les solutions analytiques.En outre, une méthode de localisation avec XFEM et la méthode Level set a été proposée afin d’améliorer l’efficacité de calcul. Elle permet de réduire le domaine de calcul près du front d’écoulement. Par conséquent, le temps de calcul est fortement réduit grâce à cette méthode. Un test d’efficacité a été fait avec des modèles simples en écoulement laminaire ou radial.Quelques exemples d’application sont présentés pour illustrer la capacité de cette méthode. Une pale d’éolienne a également traitée comme application industrielle. Enfin, une interface d’utilisateur graphique a été développée en vue de fournir une facilité des pré- et post-processus.
Numerical simulation for Resin Transfer Molding (RTM) manufacturing process is attempted by using the eXtended Finite Element Method (XFEM) combined with the level set method. XFEM allows to obtaining a good numerical precision of the pressure near the resin flow front, where its gradient is discontinuous. The enriched shape functions of XFEM are derived by using the level set values so as to correctly describe the interpolation with the resin flow front. In addition, the level set method is used to transport the resin flow front at each time step during the mold filling. The level set values are calculated by an implicit characteristic Galerkin FEM. The multi-frontal solver of IPSAP is adopted to solve the system. This work is validated by comparing the obtained results with analytic solutions.Moreover, a localization method of XFEM and level set method is proposed to increase the computing efficiency. The computation domain is reduced to the small region near the resin flow front. Therefore, the total computing time is strongly reduced by it. The efficiency test is made with simple channel or radial flow models. Several application examples are analyzed to demonstrate ability of this method. A wind turbine blade is also treated as industrial application. Finally, a Graphic User Interface (GUI) tool is developed so as to make easy the pre/post-processing of the simulation.

▼ Dans ce travail, nous nous sommes intéressés à la simulation numérique de suspensions denses d'objets immergés dans un fluide. En s'inspirant d'une méthode de segmentation d'image, nous avons développé une méthode efficace de capture d'interface permettant d'une part de localiser les structures immergées et d'autre part de gérer les contacts numériques entre les structures.Le domaine fluide/structure est représenté à l'aide de trois fonctions labels et deux fonctions distances qui permettent de localiser chaque structure et son plus proche voisin.Les interfaces sont capturées par une seule fonction level set, celle-ci est ensuite transportée par la vitesse du fluide ou par la vitesse de chaque structure. Un algorithme de multi-label fast marching permet de réinitialiser à chaque pas de temps les fonctions labels et distances dans un périmètre proche des interfaces.La gestion des contacts numériques est effectuée grâce à une force répulsive à courte portée prenant en compte l'interaction entre les objets les plus proches.Dans un premier temps, la méthode est appliquée à l'évolution de solides rigides immergés.Un modèle de pénalisation global couplé aux fonctions labels permet de calculer en une seule fois l'ensemble des vitesses des structures rigides. Les résultats obtenus montrent l'efficacité de la méthode à gérer un grand nombre de solides.Nous avons ensuite appliqué la méthode des suspensions de vésicules immergées. Ce type de simulation requiert le calcul des forces élastiques et de courbures exercées sur les membranes. Grâce au modèle proposé, seulement une force élastique et une force de courbure sont calculées pour l'ensemble des membranes à l'aide de la fonction level set et des fonctions labels.
In this work, we propose a method to efficiently capture an arbitrary number of fluid/solid or fluid/fluid interfaces, in a level-set framework. This technique, borrowed from image analysis, is introduced in the context of the interaction of several bodies immersed in a fluid. A configuration of the bodies in the fluid/structure domain is described by three label maps providing the first and second neighbours, and their associated distance functions. Only one level set function captures the union of all interfaces and is transported with the fluid velocity or with a global velocity field which takes into account the velocity of each structure. A multi-label fast marching method is then performed in a narrow-band around the interfaces allowing to update the label and distance functions. Within this framework, the numerical treatment of contacts between the structures is achieved by a short-range repulsive force depending on the distance between the closest bodies.The method is validated through the simulation of a dense suspension of rigid bodies immersed in an incompressible fluid. A global penalization model uses the label maps to follow the solid bodies altogether without a separate computation of each body velocity. Consequently, the method shows its efficiency when dealing with a large number of rigid bodies.…

A atenção selectiva na doença de Alzheimer - a manutenção do set mental nos doentes de Alzheimer.

▼ A presente Dissertação de Mestrado, após a revisão de literatura realizada no tema de interesse, colocou como objetivo estudar a atenção seletiva em doentes diagnosticados com uma provável doença de Alzheimer em estádio ligeiro. Mais precisamente, foi proposto estudar um componente executivo da atenção seletiva, designado como, set mental, sendo ainda colocada a questão se nestes sujeitos existe algum défice na capacidade de resolução de conflito.
O termo atenção diz respeito a diferentes processos cognitivos como, a orientação para um determinado estimulo, a capacidade de manter um estado de alerta e a capacidade de realizar tarefas complexas no dia-a-dia (Fernandez-Duque & Posner, 1997 cf. Fernandez-Duque & Black, 2006).
Com o objetivo de encontrarem alguma concordância quando se referem às redes atencionais, alguns autores dividiram-nas em diferentes categorias como, atenção mantida, atenção seletiva e atenção dividida. A atenção mantida é definida como a capacidade de focar a atenção numa tarefa durante um longo período de tempo (Wilkins et al. 1987 cf. Perry, Watson & Hodges, 1999). A atenção seletiva define-se como a capacidade de ignorar informação irrelevante, enquanto ocorre o processamento da informação relevante. A atenção seletiva é necessária para canalizar recursos para um número restrito de canais sensoriais, enquanto o processamento de informação paralela é suprimido (Perry, Watson & Hodges 1999 cf. Levinoff et al. 2004). A atenção dividida diz respeito á partilha de recursos cognitivos para duas tarefas que ocorrem em simultâneo (Perry, Watson & John, 2000).
A bibliografia referente às funções executivas na doença de Alzheimer relata um defeito nestas funções ainda em fases ligeiras da patologia (Albert, Moss, Tanzi & Jones, 2001; Baudic et al. 2006). Sendo o set mental um controlo executivo da atenção seletiva, demonstrou-se relevante explorá-lo neste estudo.
Desta forma, com a finalidade de cumprir o objetivo proposto, foram comparados dois grupos. O grupo experimental, constituído por sujeitos com provável doença de Alzheimer em fases iniciais (n=7) e um grupo de controlo, constituído por sujeitos sem qualquer patologia (n=7). Os dois grupos realizaram um paradigma de task-.switching onde foram manipuladas as exigências criadas ao set mental destes sujeitos. Para obtenção dos resultados estatísticos foram contabilizadas as médias dos tempos de resposta obtidos pelos sujeitos pertencentes aos dois grupos e comparadas entre si.
Após realizada análise estatística, não se verificou qualquer diminuição no set mental de sujeitos com doença de Alzheimer em fases iniciais, no entanto verificou-se um défice na resolução de conflito
This project aimed to study selective attention in patients diagnosed as mild Alzheimer’s disease, specifically an executive subcomponent of selective attention called, mental set. In this study we, also, wanted to verify if there was any deficit in situations that required conflict resolution.
The term attention refers to several different cognitive abilities such as,…

▼ Mestrado em Radioterapia
Este trabalho científico tem como objetivo avaliar o impacto da periodicidade da aquisição de imagens de verificação da área a tratar, na administração dos tratamentos e diminuição das incertezas da variação dos desvios de doentes com diagnóstico de cancro da próstata submetidos a radioterapia conformacional. Foram avaliadas 1139 radiografias (571 incidência anterior e 568 incidência lateral), de um total de 80 doentes escolhidos aleatoriamente. Aplicou-se dois protocolos, de aquisição de imagens, com periodicidade distintas. As imagens portais foram comparadas com as Radiografias Digitalmente Reconstruídas em sistema de planeamento computadorizado Eclipse, a partir das tomografias. É verificado, com base neste trabalho que a variável independente “periodicidade das imagens portais” influencia a variável dependente “desvios de posicionamento”, isto é, existe uma relação implícita entre a frequência na aquisição das imagens portais e os valores de desvios de posicionamento. Os dados não foram conclusivos para determinar qual dos protocolos estudados estaria mais perto da idealidade, cabe a cada instituição, de acordo com a sua rotina diária e da condição de cada doente, optar pela melhor solução.
ABSTRACT - The objective of this scientific work is to evaluate the impact of the timing of the image acquisition scan of the area to be treated, the administration of treatments and reducing uncertainties of variation of the deviations of patients diagnosed with prostate cancer sent to conformational radiotherapy. 1139 radiographs (anterior view 571 and lateral view 568) were evaluated in a total of 80 randomly selected patients. Two protocols of image acquisition with different periodicity were applied. The portal images were compared to Digitally Reconstructed Radiographs in computerized planning system Eclipse from CT scans. Based on this work it was found the independent variable “frequency of portal image” influences the dependent variable “deviation positioning”, i.e, there´s an implicit relationship between the frequency of the acquisition of portal image and values of setup errors. The data were inconclusive to determine which of the protocols would be near to the ideal, it is up to each institution to choose the best solution according to their daily routine and the condition of each patient.

▼ Compreender a funcionalidade de uma criança é um desafio persistente em contextos de saúde e educação. Na tentativa de superar esse desafio, em 2007, a Organização Mundial de Saúde desenvolveu a Classificação Internacional de Funcionalidade, Incapacidade e Saúde para Crianças e Jovens (CIF-CJ) como o primeiro sistema de classificação universal para documentar a saúde e funcionalidade da criança. Apesar de a CIF-CJ não ser um instrumento de avaliação e intervenção, tem, no entanto, a capacidade de servir de enquadramento para o desenvolvimento de ferramentas adaptadas às necessidades dos seus utilizadores.
Considerando que no contexto escolar, a escrita manual encontra-se entre as atividades mais requeridas para a participação plena de uma criança, parece ser pertinente a definição de um conjunto de códigos destinados a caracterizar o perfil de funcionalidade de uma criança, no que se refere à escrita manual. O objetivo deste estudo foi, pois, o desenvolvimento de um conjunto preliminar de códigos baseado na CIF-CJ que possa vir a constituir um code set para a escrita manual.
Dada a complexidade do tema e atendendo a que se pretende alcançar consenso entre os especialistas sobre quais as categorias da CIF-CJ que devem ser consideradas, optou-se pela utilização da técnica de Delphi. A escolha da metodologia seguiu a orientação dos procedimentos adotados pelo projeto Core Set CIF. De dezoito profissionais contactados, obtiveram-se respostas de sete terapeutas ocupacionais com experiência em pediatria, que participaram em todas as rondas. No total, três rondas de questionários foram realizadas para atingir um consenso, com um nível de concordância, previamente definido, de 70%.
Deste estudo resultou um conjunto preliminar de códigos com 54 categorias da CIF-CJ (16 categorias de segundo nível, 14 categorias de terceiro nível e uma categoria de quarto nível), das quais 31 são categorias das funções do corpo, uma categoria das estruturas do corpo, 12 categorias de atividades e participação e 10 categorias de fatores ambientais.
Este estudo é um primeiro passo para o desenvolvimento de um code set para a escrita manual baseado na CIF-CJ , sendo claramente necessário a realização de mais pesquisas no contexto do desenvolvimento e da validação deste code set.
Understanding the functioning of a child is a persistent challenge in the context of health and education. In order to try to bridge this gap, in 2007, the World Health Organization develop the International Classification of Functioning, Disability and Health for Children and Youth (ICF-CY) as the first universal classification system to document child´s health and functioning. Despite the ICF-CY is not a tool for assessment and intervention, as a classification system has the ability to serve as a framework for the development of tools tailored to the needs of its users.
Considering that in the school setting, handwriting is among one of the most required activities one child needs to perform to participate fully, it seemed of great relevance to attempt to define a…

▼ A CIF é uma ferramenta universal desenvolvida pela OMS que permite a
classificação de funcionalidade e incapacidade, através de uma visualização global do que
condiciona o desempenho do indivíduo na concretização de atividades e na participação
em ocupações. A ideologia da CIF e os seus componentes interrelacionam-se com a
essência da TO, indo ao encontro dos modelos da profissão.
As UCCI constituem uma atualidade em Portugal e o terapeuta ocupacional é um
dos profissionais obrigatórios na equipa multidisciplinar destas unidades. Atendendo à
relevância internacional da CIF, à sua ligação com a TO e à necessidade de tornar a CIF
operacional na prática clínica diária dado que é uma ferramenta complexa e extensa, é
objetivo deste estudo contribuir para a construção de um code set da CIF para terapeutas
ocupacionais que exercem funções em UCCI, especificamente em UC, UMDR e ULDM.
Para a concretização desta investigação, utilizou-se a técnica de Delphi, que
envolveu duas rondas. Na primeira ronda foi possível contar com a participação de 37
terapeutas ocupacionais experientes na área, uma vez que exercem funções em UCCI, e na
segunda ronda contou-se com a participação de 20 elementos.
Obtiveram consenso na última ronda de Delphi um total de 96 categorias,
constituindo esta listagem uma proposta de code set para UCCI. No que se refere às
tipologias de unidades, 69 categorias obtiveram consenso em UC, 91 em UMDR e 41 em
ULDM.
Concluiu-se que a criação de code sets poderá constituir uma mais-valia em
contexto de equipa multidisciplinar das UCCI, sendo uma forma de tornar a CIF
operacional na prática clínica diária.
The ICF is a universal tool developed by WHO, which allows the classification of
functioning and disability, through a global view of what determines the individual's
performing activities and participation in occupations. The ICF ideology and its
components interrelate with the OT essence, meeting the models of one´s profession.
The UCCI are an actuality in Portugal and the occupational therapist is a required
professional in the multidisciplinary team in these units. Owing to the international
importance of the ICF, its connection with OT and the need to make the ICF work in daily
clinical practice since it is a complex and extensive tool, the objective of this study is to
contribute to the construction of a code set of the ICF for occupational therapists working
at UCCI, specifically in UC, UMDR and ULDM.
To accomplish this investigation, we used the Delphi technique, which involved
two rounds. In the first round it was possible to count on the participation of 37
occupational therapists experienced in the area, since they work in UCCI, and the second
round we counted on the participation of 20 elements.
In the last Delphi round consensus was obtained in a total of 96 categories, making
this list a proposed code set for UCCI. Concerning the unit types, 69 categories reached
consensus at UC, 91 at UMDR and 41 at ULDM.
We came to the conclusion that the creation of code sets can be an asset in the
context of a…

▼ Dans les années à venir, l'industrie
de la microélectronique doit développer
de nouvelles filières technologiques qui pourront devenir des successeurs ou des compléments
de la technologie CMOS ultime. Parmi ces technologies émergentes relevant du domaine « Beyond CMOS », ce travail
de recherche porte sur les transistors mono-électroniques (
SET) dont le fonctionnement est basé sur la quantification
de la charge électrique, le transport quantique et la répulsion Coulombienne. Les SETs doivent être étudiés à trois niveaux : composants, circuits et système. Ces nouveaux composants, utilisent à leur profit le phénomène dit
de blocage
de Coulomb permettant le transit des électrons
de manière séquentielle, afin
de contrôler très précisément le courant véhiculé. En effet, l'émergence du caractère granulaire
de la charge électrique dans le transport des électrons par effet tunnel, permet d'envisager la réalisation
de remplaçants potentiels des transistors ou
de cellules mémoire à haute densité d'intégration, basse consommation. L'objectif principal
de ce travail
de thèse est d'explorer et d'évaluer le potentiel des transistors mono-électroniques double-grille métalliques (DG-SETs) pour les circuits logiques numériques.
De ce fait, les travaux
de recherches proposés sont divisés en trois parties : i) le développement des outils
de simulation et tout particulièrement un modèle analytique
de DG-
SET ; ii) la conception
de circuits numériques à base
de DG-SETs dans une approche « cellules standards » ; et iii) l'exploration d'architectures logiques versatiles à base
de DG-SETs en exploitant la double-grille du dispositif. Un modèle analytique pour les DG-SETs métalliques fonctionnant à température ambiante et au-delà est présenté. Ce modèle est basé sur des paramètres physiques et géométriques et implémenté en langage Verilog-A. Il est utilisable pour la conception
de circuits analogiques ou numériques hybrides
SET-CMOS. A l'aide
de cet outil, nous avons conçu, simulé et évalué les performances
de circuits logiques à base
de DG-SETs afin
de mettre en avant leur utilisation dans les futurs circuits ULSI. Une bibliothèque
de cellules logiques, à base
de DG-SETs, fonctionnant à haute température est présentée. Des résultats remarquables ont été atteints notamment en termes
de consommation d'énergie.
De plus, des architectures logiques telles que les blocs élémentaires pour le calcul (ALU, SRAM, etc.) ont été conçues entièrement à base
de DG-SETs. La flexibilité offerte par la seconde grille du DG-
SET a permis
de concevoir une nouvelle famille
de circuits logiques flexibles à base
de portes
de transmission. Une réduction du nombre
de transistors par fonction et
de consommation a été atteinte. Enfin, des analyses Monte-Carlo sont abordées afin
de déterminer la robustesse des circuits logiques conçus à l'égard des dispersions technologiques.

▼ RESUMO: Os estudos sobre a funcionalidade da população idosa têm uma representação importante naquilo que é o atual conhecimento da demografia do mundo.
Portugal posiciona-se e perspetiva-se como pertencendo aos países mais envelhecidos, possuindo uma rede
de cuidados pós-agudos – a Rede Nacional
de Cuidados Continuados Integrados (RNCCI)– que assiste uma parcela importante dessa população.
Os aspetos conceptuais da funcionalidade
de acordo com a OMS e operacionalizados pela
Classificação Internacional
de Funcionalidade (CIF), não mereceram até agora suficiente aplicabilidade no nosso país, inviabilizando a possibilidade
de oferecermos contributos para a sua
operacionalização. Da mesma forma, també
m os Core Sets da Classificação não têm sido sujeitos a processos
de validação que contemplem amostras portuguesas, mantendo-se desconhecimento da especificidade dos fatores contextuais na nossa população.
O presente estudo tem como objetivos conhecer a evolução da funcionalidade dos idosos assistidos na RNCCI na região do Algarve nas unidades
de convalescença e média duração, validar o Core
Set Geriátrico da OMS e propor uma versão abreviada da sua modalidade abrangente, no contexto destes cuidados.
A amostra constituída por 451 idosos, dos quais 62,1% eram mulheres, revelou na pré-morbilidade níveis favoráveis
de funcionalidade, com exceção para as Atividades Domésticas. Contudo, os mais
idosos (≥ 85 anos), os indivíduos sem escolaridade, as mulheres e os viúvos/solteiros apresentaram
mais casos desfavoráveis quando comparados com os seus pares.
Na evolução da funcionalidade observámos melhorias significativas em todos os domínios
avaliados, com diferenças relativamente à idade e à escolaridade; apesar dos resultados positivos os mais idosos e os indivíduos sem escolaridade apresentaram níveis inferiores
de evolução.
No entanto, a funcionalidade alcançada revelou ficar com resultados significativamente inferiores na comparação com aquela que os indivíduos possuíam na pré-morbilidade. Os modelos
de regressão revelaram que as Funções Mentais, a Perceção do Estado
de Saúde e a atividade Usar o
Telefone, foram as variáveis que melhor explicaram os outcomes da funcionalidade alcançada. A validação do Core
Set Geriátrico foi possível na maioria das categorias, sendo que foi no componente das Funções do Corpo onde esse processo revelou maior fragilidade. As Funções Neuromusculoesqueléticas e Relacionadas com o Movimento foram aquelas que registaram em
ambos os momentos avaliativos frequências mais elevadas
de deficiência, enquanto no
componente Atividades & Participação isso ocorreu na atividade Utilização dos Movimentos Finos da Mão. Os capítulos Apoios e Relacionamentos e Atitudes foram considerados os Fatores Ambientais mais Facilitadores mas també
m com maior impacto Barreira.
A proposta para o Core
Set Geriátrico Abreviado resultou das categorias independentes que explicaram os modelos da funcionalidade alcançada e cujo resultado engloba um conjunto
de 27 categorias, com um enfoque importante no componente…

▼ Nach der Renaissance war es literarisch um Giotto ruhig geworden. Erst Ende des 18. und im 19. Jahrhundert kam wieder Interesse für ihn auf. Bei einem Großteil der Publikationen bzw. Textstellen handelte es sich um kurze Erwähnungen Giottos in „Geschichten zur Kunstgeschichte“ und ähnlichen Überblickswerken. John Ruskin und Henry Thode waren im 19. Jahrhundert unter den wenigen, die Giotto ausführliche Betrachtungen widmeten. Aus den Schriften beider Autoren konstituieren sich eigenwillige Giotto-Bilder, die in ihrer Art singulär sind. Neben den pointierten Aussagen und der willkürlichen Auswahl ihrer Themen, ist auch die Sprache der Autoren im Vergleich mit den meisten zeitgleichen Publikationen auffällig persönlich gefärbt.
Auf Basis einer möglichst lückenlosen Erfassung von Originalzitaten aus den verschiedenen Publikationen der Autoren wird mittels textkritischer Analyse und Deduktion das jeweilige Giotto-Bild rekonstruiert und zu Themenkreise, wie Giottos Biographie und sein Charakter, die Werkverzeichnisse gemäß den Zuordnungen von John Ruskin und Henry Thode sowie darauf aufbauend, Giotto als Neuerer, Maler, Baumeister und Bildhauer, zusammengefasst. Die speziellen Meinungen und persönlichen Schwerpunkte der Autoren werfen die Frage nach den Hintergründen dafür auf. John Ruskins Bild von Giotto ist das eines an der Renaissance geschulten kulturinteressierten Menschen des 19. Jahrhunderts. Viele seiner Aussagen werden beeinflusst vom starken Interesse für das Handwerk und die Gotik; ideologisch umrahmt sind sie von seinem persönlichen Zugang zur Religion. Henry Thodes Giotto-Bild steht einerseits in enger Verbindung mit dem kulturellen Umfeld des Wagner-Kreises und andererseits mit seiner Begeisterung für Franz von Assisi sowie seinem Interesse für die Kunst der Renaissance. Henry Thodes Giotto-Bild ist ein idealisiertes Bild, das auf großen Gefühlen und Stimmungen basiert.
After the Renaissance only few authors wrote about Giotto. Interest in his work again arose at the end of the 18th and in the 19th century. Most publications were overview works, dealing with the history of art, the artist himself just occurred in short passages. In the 19th century only John Ruskin and Henry Thode dedicated detailed considerations on Giotto. In the writings of both authors you find unconventional, unique “pictures” of Giotto. Their emphasised statements and the arbitrary choice of their subjects, the language of both authors offers personally colours in comparison to most simultaneous publications.
By a wide range of original statements from different publications of the authors the picture of Giotto gets reconstructed, using text-critical analysis and deducation and is summarised to several topics. These topics are Giotto’s biography and his character, the work list according to the attribution made by John Ruskin and Henry Thode, further Giotto as an innovator, painter, architect and sculptor. Why Ruskin and Thode had such specific opinions and personal focuses on Giotto`s life and work? Ruskin’s picture of Giotto is…

▼ Um dos teoremas conhecidos de Poincaré afirma: Seja f um homeomorfismo do círculo que preserva orientação. Se p/q, com mdc(p, q) = 1, é o número de rotação de f, então f possui um ponto periódico de período q. Quando o conceito de número de rotação para um homeomorfismo do círculo é generalizado para um homeomorfismo f : T2 ? T2 homotópico à identidade, o resultado é um subconjunto convexo do plano R2, chamado conjunto de rotação e é denotado por ½(F) onde F é um levantamento de f. No caso que ½(F) tem interior não vazio, J. Franks obteve resultados análogos ao Teorema de Poincaré. Nesta dissertação estudamos um resultado análogo, obtido por Jonker e Zhang, quando ½(F) não tem interior. Mais precisamente: assumimos que ½(F) é um segmento de reta com inclinação irracional e mostramos que se 1 n(p1, p2) ? ½(F), com mdc(p1, p2, n) = 1, então f possui um ponto periódico de período n
One of the well know results of Poincaré state: Let f be an orientation preserving circle homeomorphism. If p/q, with mdc(p, q) = 1, is the rotation number of f, then there is a periodic point for f whose period is q. When the concept of rotations number, for orientation preserving circle homeomorphism, is generalized for torus homeomorphism f : T2 ? T2 that are homotopic to the identity, it results in a convex subset of R2, called rotation set and is denoted by ½(F) where F is a lifting of f. In the case that ½(F) has non-empty interior, J. Franks proved similar results to the Poincaré Theorem. In this work, when ½(F) has empty interior, we study an similar result obtained by Jonker and Zhang. More precisely: they suppose that the rotation set ½(F) is a line segment with irrational slope and demonstrate that if 1 n(p1, p2) ? ½(F), with mdc(p1, p2, n) = 1, then f has a periodic point of period n

▼ Nous présentons une nouvelle méthode de type frontière immergée (immersed boundary method, ou méthode IB) pour le calcul d'écoulements visqueux incompressibles en géométries irrégulières. Dans les méthodes IB , la frontière irrégulière de la géométrie n'est pas alignée avec la grille de calcul, et le point crucial de leur développement demeure le traitement numérique des cellules fluides qui sont coupées par la frontière irrégulière, appelées cut-cells. La partie dédiée à la résolution des équations de Navier-Stokes de notre méthode IB, appelée méthode LS-STAG , repose sur la méthode MAC pour grilles cartésiennes décalées, et sur l'utilisation d'une fonction de distance signée (la fonction level-set ) pour représenter précisément les frontières irrégulières du domaine. L'examen discret des lois globales de conservation de l'écoulement (masse, quantité de mouvement et énergie cinétique) a permis de bâtir une discrétisation unifiée des équations de Navier-Stokes dans les cellules cartésiennes et les cut-cells . Cette discrétisation a notamment la propriété de préserver la structure à 5 points du stencil original et conduit à une méthode extrêmement efficace sur le plan du temps de calcul en comparaison à un solveur non-structuré. La précision de la méthode est évaluée pour l'écoulement de Taylor-Couette et sa robustesse éprouvée par l'étude de divers écoulements instationnaires, notamment autour d'objets profilés. Le champ d'application de notre solveur Newtonien s'étend au cas d'écoulements en présence de géométries mobiles, et la méthode LS-STAG s'avère être un outil prometteur puisqu'affranchie des étapes systématiques (et coûteuses) de remaillage du domaine. Finalement, la première application d'une méthode IB au calcul d'écoulements de fluides viscoélastiques est présentée. La discrétisation de la loi constitutive est basée sur la méthode LS-STAG et sur l'utilisation d'un arrangement totalement décalé des variables dans tout le domaine assurant le couplage fort requis entre les variables hydrodynamiques et les composantes du tenseur des contraintes élastiques. La méthode est appliquée au fluide d'Oldroyd-B en écoulement dans une contraction plane 4:1 à coins arrondis.
This thesis concerns the development of a new Cartesian grid / immersed boundary (IB) method for the computation of incompressible viscous flows in two-dimensional irregular geometries. In IB methods, the computational grid is not aligned with the irregular boundary, and of upmost importance for accuracy and stability is the discretization in cells which are cut by the boundary, the so-called ``cut-cells''. In this thesis, we present a new IB method, called the LS-STAG method, which is based on the MAC method for staggered Cartesian grids and where the irregular boundary is sharply represented by its level-set function. This implicit representation of the immersed boundary enables us to calculate efficiently the geometry parameters of the cut-cells. We have achieved a novel discretization of the fluxes in the cut-cells by enforcing the strict…

▼ RESUMO
O terrorismo tem sido alvo da atenção crescente de todos, desde o cidadão anónimo aos governantes mais influentes no Mundo. Também o modo como a informação sobre actos terroristas é veiculada e percebida tem vindo a suscitar particular interesse por parte dos investigadores. No entanto, os estudos em torno da Gestão da Percepção t êm sido pautados por uma elevada dispersão de dados. Partindo de uma linha humanista-interpretativa, a presente dissertação procurou compreender o papel dos media e da Gestão da Percepção nas novas conflitualidades, recorrendo à análise de perspectivas e estudos recentes dos media, das neurociências e da psicologia do terrorismo. Sugere-se que é possível condicionar a percepção e as acções do adversário e que os media podem ser utilizados como mult iplicador de força.
ABSTRACT
From the ordinary citizen to the most influent World leader, everyone has been paying more and more attention to terrorism. Also the way information about terrorist acts is broadcasted and perceived has raised particular interest among researchers. Nonetheless, data from studies concerning the Perception Management are very diffuse given the multiplicity and diversity of sciences that covers this subject of study. From a humanistic-interpretive methodology, this dissertation was an effort to bring together ontributions from several areas of study, aimed at understanding the role of media and Perception Management in modern wars. We analyzed perspectives and recent studies of the media, neuroscience and psychology of terrorism. It is suggested that it is possible to bias adversary‟s perceptions and actions and that the media can be used as a force multiplier.

▼ Failure of coastal protection due to flooding is mainly caused by a combination of high water level and waves. If one considers these as independent variables, the probability of failure can be calculated easily, but this would be an incorrect assumption. These two variables are
de-pendent, so a method suitable for multivariate statistics is to be applied, if one does not want to over- of underestimate the probability of failure. 'Method
de Haan' is a method that is suit-able for extrapolation of dependent variables. In general this method shifts a cloud of observa-tions in exponential space into the area of failure or other relevant area. Because this method does not have a physical basis it is important that the relation between the variables that are used, holds in cases of extreme events if one wants to determine events with a very low fre-quency of occurrence.
In this study the relation between (skewed)
set-up and wind speed is examined. Most impor-tant reason to examine these variables is that at RIKZ (National Institute for Coastal and Ma-rine Management) these variables are used to determine the hydraulic variables in case of extreme events. A relation between water level and wave height is used to determine the cor-responding wave heights.
Because the highest water levels are of importance skewed
set-up is used as a variable instead of water level. By using this variable a more homogeneous data
set is generated and the high-est water level can be constructed afterwards. Skewed
set-up is the surge effect determined by the highest water level around during a tidal cycle, where this moment does not necessarily coincides with the moment the astronomical tide occurs. Data of four locations are used, covering a period of 23 years of simultaneous data. In order to use homogeneous data selections based on wind speed and
set-up are carried out. Three dif-ferent thresholds are imposed for these selection procedures. The extrapolation path with method
de Haan using these data sets is compared with a reference situation and results of hydrodynamic model runs where manipulated storm fields are used as input. In 'WAQUA', over 80 model runs are carried out, where a wind and atmospheric pressure field of the 1953 storm, is manipulated. The intensities, storm duration and phase of the storm relative to the astronomical tide are varied. Based on model runs with WAQUA the relation between skewed
set-up and aver-age/maximum wind speed at a certain location appears to hold under extreme circumstances. However, only one wind drag relation (Charnock) is used in the model runs. The relation be-tween skewed
set-up and average/maximum wind speed with method
de Haan (extrapolation path) is physically more plausible if the asymptotic dependence is good, judged by the asymp-totic plots. The extrapolation path also is better if data are selected based on thresholds re-garding
set-up. These paths lie closer to the reference situation, although strongly varying with different thresholds that were used.

▼ El objetivo central
de esta memoria es estudiar un problema inverso geométrico en mecánica
de fluidos y realizar un procedimiento
de reconstrucción numérica que permita recuperar distintos cuerpos rígidos inmersos en un fluido viscoso, siendo
de especial interés el caso
de cuerpos no convexos. Para llevar a cabo esta reconstrucción numérica se utiliza el llamado método level
set. El método level
set fue introducido por S. Osher y J. A. Sethian como un método simple y versátil para calcular y analizar el movimiento
de una interface Γ bajo un campo
de velocidades V, en dos y tres dimensiones, donde Γ es la frontera
de una región Ω. Por otra parte en los problemas inversos geométricos, es decir, problemas donde la incógnita es una forma geométrica, el enfoque estándar para la solución
de estos consiste en parametrizar la forma geométrica y aplicar métodos
de regularización directamente a la parametrización. Este enfoque sufre
de la limitación que para obtener aproximaciones convergentes se tiene que tener un conocimiento a priori
de la estructura y topología
de la forma geométrica buscada. Por esta razón, recientemente se han considerado enfoques alternativos para la solución
de problemas
de reconstrucción
de formas geométricas, entre ellos el método level
set, el cual fue utilizado inicialmente en el procesamiento
de imágenes digitales.
La presente memoria esta estructurada
de la siguiente manera. En el Capítulo 1 se realiza una introducción al trabajo realizado. En el Capítulo 2 se hace una introducción a los problemas inversos, se define el problema inverso geométrico
de detección
de obstáculos dentro
de un fluido y se muestran los resultados
de identificabilidad y estabilidad para este problema. En el Capítulo 3 se estudia el método
de los elementos finitos y la resolución del problema
de Stokes usando dicho método, en donde se muestran el algoritmo
de Uzawa y el algoritmo numérico para Stokes usado en esta memoria. En el Capítulo 4 se presenta el método
de diferenciación con respecto al dominio, el cual resulta fundamental para posteriormente realizar el cálculo
de la primera derivada local del funcional
de costo asociado al problema inverso geométrico en estudio. En el Capítulo 5 se presenta el método level
set, estudiando los movimientos por curvatura media y en dirección normal, la ecuación
de reinicialización y la extensión del campo
de velocidades. Además, se muestra su aplicación a la optimización
de formas y se utiliza la diferenciación con respecto al dominio para deducir la expansión
de primer orden del funcional
de costo asociado al problema. En el Capítulo 6 se muestran los principales resultados numéricos obtenidos al usar el método level
set, recuperando diferentes obstáculos (incluyendo algunos
de geometría no convexa), para lo cual se ha utilizado el programa FreeFem. Finalmente, se presentan las principales conclusiones obtenidas
de este trabajo
de título.

▼ Dans les années à venir, l’industrie de la microélectronique doit développer de nouvelles filières technologiques qui pourront devenir des successeurs ou des compléments de la technologie CMOS ultime. Parmi ces technologies émergentes relevant du domaine ‘‘Beyond CMOS’’, ce travail de recherche porte sur les transistors mono-électroniques (SET) dont le fonctionnement est basé sur la quantification de la charge électrique, le transport quantique et la répulsion Coulombienne. Les SETs doivent être étudiés à trois niveaux : composants, circuits et système. Ces nouveaux composants, utilisent à leur profit le phénomène dit de blocage de Coulomb permettant le transit des électrons de manière séquentielle, afin de contrôler très précisément le courant véhiculé. Ainsi, le caractère granulaire de la charge électrique dans le transport des électrons par effet tunnel, permet d’envisager la réalisation de transistors et de cellules mémoires à haute densité d’intégration, basse consommation. L’objectif principal de ce travail de thèse est d’explorer et d’évaluer le potentiel des transistors mono-électroniques double-grille métalliques (DG-SETs) pour les circuits logiques numériques. De ce fait, les travaux de recherches proposés sont divisés en trois parties : i) le développement des outils de simulation et tout particulièrement un modèle analytique de DG-SET ; ii) la conception de circuits numériques à base de DGSETs dans une approche ‘‘cellules standards’’ ; et iii) l’exploration d’architectures logiques versatiles à base de DG-SETs en exploitant la double-grille du dispositif. Un modèle analytique pour les DG-SETs métalliques fonctionnant à température ambiante et au-delà est présenté. Ce modèle est basé sur des paramètres physiques et géométriques et implémenté en langage Verilog-A. Il est utilisable pour la conception de circuits analogiques ou numériques hybrides SET-CMOS. A l’aide de cet outil, nous avons conçu, simulé et évalué les performances de circuits logiques à base de DG-SETs afin de mettre en avant leur utilisation dans les futurs circuits ULSI. Une bibliothèque de cellules logiques, à base de DG-SETs, fonctionnant à haute température est présentée. Des résultats remarquables ont été atteints notamment en terme de consommation d’énergie. De plus, des architectures logiques telles que les blocs élémentaires pour le calcul (ALU, SRAM, etc.) ont été conçues entièrement à base de DG-SETs. La flexibilité offerte par la seconde grille du DG-SET a permis de concevoir une nouvelle famille de circuits logiques flexibles à base de portes de transmission. Une réduction du nombre de transistors par fonction et de consommation a été atteinte. Enfin, des analyses Monte-Carlo sont abordées afin de déterminer la robustesse des circuits logiques conçus à l'égard des dispersions technologiques.
In this work, we have presented a physics-based analytical SET model for hybrid SET-CMOS circuit simulations. A realistic SET modeling approach has been used to provide a compact SET model that takes several conduction mechanisms into…
