On s'intéresse dans cette thèse à l'enlacement du mouvement Brownien plan autour des points, dans la succession des travaux de Wendelin Werner en particulier. Dans le premier chapitre, on motive cette étude par celle du cas des courbes plus lisses que le mouvement Brownien. On y démontre notamment une formule de Green pour l'intégrale de Young, sans hypothèse de simplicité de la courbe. Dans le chapitre 2, on étudie l'aire de l'ensemble des points autour desquels l'enlacement du mouvement brownien est plus grand que N. On donne, au sens presque sûr et dans les espaces Lp, une estimation asymptotique au second ordre de cette aire lorsque N tend vers l'infini. Le chapitre 3 est dévoué à la preuve d'un résultat qui montre que les points de grands enlacements se répartissent de manière très équilibrée le long de la trajectoire. Dans le chapitre 4, on utilise les résultats des deux précédents chapitres pour énoncer une formule de Green pour le mouvement brownien. On étudie aussi l'enlacement moyen de points répartis aléatoirement dans le plan. On montre que cet enlacement moyen converge en distribution (presque surement pour la trajectoire), non pas vers une constante (qui serait alors l’aire de Lévy) mais vers une variable de Cauchy centrée en l’aire de Lévy. Dans les deux derniers chapitres, on applique les idées des précédents chapitres pour définir et étudier l’aire de Lévy du mouvement Brownien lorsque la mesure d’aire sous-jacente n’est plus la mesure de Lebesgue mais une mesure aléatoire particulièrement irrégulière. On traite le cas du chaos multiplicatif gaussien en particulier, mais la méthode s’applique dans un cadre plus généralWe study the windings of the planar Brownian motion around points, following the previous works of Wendelin Werner in particular. In the first chapter, we motivate this study by the one of smoother curves. We prove in particular a Green formula for Young integration, without simplicity assumption for the curve. In the second chapter, we study the area of the set of points around which the Brownian motion winds at least N times. We give an asymptotic estimation for this area, up to the second order, both in the almost sure sense and in the Lp spaces, when N goes to infinity.The third chapter is devoted to the proof of a result which shows that the points with large winding are distributed in a very balanced way along the trajectory. In the fourth chapter, we use the results from the two previous chapters to give a new Green formula for the Brownian motion. We also study the averaged winding around randomly distributed points in the plan. We show that, almost surely for the trajectory, this averaged winding converges in distribution, not toward a constant (which would be the Lévy area), but toward a Cauchy distribution centered at the Lévy area. In the last two chapters, we apply the ideas from the previous chapters to define and study the Lévy area of the Brownian motion, when the underlying area measure is not the Lebesgue measure anymore, but instead a random and highly irregular measure. We deal with the case of the Gaussian multiplicative chaos in particular, but the tools can be used in a much more general framework

The Green formula is proved for boundary value problems (BVPs), when "basic" operator is arbitrary partial differential operator with variable matrix coefficients and "boundary" operators are quasi-normal with vector-coeficients. If the system possesses the fundamental solution, representation formula for a solution is derived and boundedness properties of participating layer potentials from function spaces on the boundary (Besov, Zygmund spaces) into appropriate weighted function spaces on the inner and the outer domains are established. Some related problems are discussed in conclusion: traces of functions from weighted spaces, traces of potential-type functions, Plemelji formulae,Calderón projections, restricted smoothness of the underlying surface
and coefficients. The results have essential applications in investigations of BVPs by the potential method, in apriori estimates and in asymptotics of solutions.

Green formulae for elliptic cone differential operators are established. This is achieved by an accurate description of the maximal domain of an elliptic cone differential operator and its formal adjoint; thereby utilizing the concept of a discrete asymptotic type. From this description, the singular coefficients replacing the boundary traces in classical Green formulas are deduced.

The Malliavin-Thalmaier formula was introduced for simulation of high dimensional probability density functions. But when this integration by parts formula is applied directly in computer simulations, we show that it is unstable. We propose an approximation to the Malliavin-Thalmaier formula. In this paper, we find the order of the bias and the variance of the approximation error. And we obtain an explicit Malliavin-Thalmaier formula for the calculation of Greeks in finance. The weights obtained are free from the curse of dimensionality.

In questa tesi vengono analizzate le principali caratteristiche delle funzioni armoniche, che sono funzioni che risolvono l'equazione di Laplace. Vengono inizialmente definite e dimostrate le formule di rappresentazione di Green, dopo aver definito le relative identità e la formula di Green, e viene analizzato il nucleo di Poisson. Successivamente vengono descritte le formule di media e vengono proposte alcune applicazioni, come la disuguaglianza di Harnack e il teorema di Liouville. Infine viene proposto un approccio alla risoluzione del problema di Dirichlet, mediante il metodo di Perron. Come premessa a tale metodo vengono definite e descritte le funzioni superarmoniche e subarmoniche.

In questo lavoro studiamo le funzioni armoniche e le loro proprietà: le formule di media, il principio del massimo e del minimo (forte e debole), la disuguaglianza di Harnack e il teorema di Louiville. Successivamente scriviamo la prima e la seconda identità di Green, che permettono di ottenere esplicitamente la soluzione fondamentale dell’equazione di Laplace, tramite il calcolo delle soluzioni radiali del Laplaciano. Introduciamo poi la funzione di Green, da cui si ottiene una formula di rappresentazione per le funzioni armoniche. Se il dominio di riferimento è una palla, la funzione di Green può essere determinata esplicitamente, e ciò conduce alla rappresentazione integrale di Poisson per le funzioni armoniche in una palla.

Повний текст джерелаАнотація:
L'équation de la chaleur est un phénomène macroscopique, émergeant après une limite d’échelle diffusive (en espace et en temps) d’un système d'oscillateurs couplés. Lorsque les interactions entre oscillateurs sont linéaires, l'énergie évolue de manière balistique, et la conductivité thermique est infinie. Certaines non-linéarités doivent donc apparaître au niveau microscopique, si l’on espère observer une diffusion normale. Pour apporter de l'ergodicité, on ajoute à la dynamique déterministe une perturbation stochastique qui conserve l'énergie. En premier lieu nous étudions la dynamique Hamiltonienne d'un système d'oscillateurs linéaires, perturbé par un bruit stochastique dégénéré conservatif. Ce dernier transforme à des temps aléatoires les vitesses en leurs opposées. On montre que l'évolution macroscopique du système est caractérisée par un système parabolique non-linéaire couplé pour les deux lois de conservation du modèle. Ensuite, nous supposons que les oscillateurs évoluent en environnement aléatoire. La perturbation stochastique est très dégénérée, et on prouve que le champ de fluctuations de l'énergie à l'équilibre converge vers un processus d'Ornstein-Uhlenbeck généralisé dirigé par l’équation de la chaleur.Il est désormais connu que les systèmes unidimensionnels présentent une diffusion anormale lorsque le moment total est conservé en plus de l'énergie. Dans une troisième partie, on considère deux perturbations, l'une préservant le moment, l'autre détruisant cette conservation. En faisant décroître l'intensité de la seconde perturbation, on observe une transition de phase entre un régime de diffusion normale et un régime de superdiffusionThe heat equation is known to be a macroscopic phenomenon, emerging after a diffusive rescaling of space and time. In linear systems of interacting oscillators, the energy ballistically disperses and the thermal conductivity is infinite. Since the Fourier law is not valid for linear interactions, non-linearities in the microscopic dynamics are needed. In order to bring ergodicity to the system, we superpose a stochastic energy conserving perturbation to the underlying deterministic dynamics.In the first part we study the Hamiltonian dynamics of linear coupled oscillators, which are perturbed by a degenerate conservative stochastic noise. The latter flips the sign of the velocities at random times. The evolution yields two conservation laws (the energy and the length of the chain), and the macroscopic behavior is given by a non-linear parabolic system.Then, we suppose the harmonic oscillators to evolve in a random environment, in addition to be stochastically perturbed. The noise is very degenerate, and we prove a macroscopic behavior that holds at equilibrium: precisely, energy fluctuations at equilibrium evolve according to an infinite dimensional Ornstein-Uhlenbeck process driven by the linearized heat equation.Finally, anomalous behaviors have been observed for one-dimensional systems which preserve momentum in addition to the energy. In the third part, we consider two different perturbations, the first one preserving the momentum, and the second one destroying that new conservation law. When the intensity of the second noise is decreasing, we observe (in a suitable time scale) a phase transition between a regime of normal diffusion and a regime of super-diffusion

Accurate electronic structure calculations are becoming more and more important because of the increasing need for information about systems which are hard to perform experiments on. Databases compiled from theoretical results are also being used more than ever for applications, and the reliability of the theoretical methods are of utmost importance. In this thesis, the present limits on theoretical alloy calculations are investigated and improvements on the methods are presented. A short introduction to electronic structure theory is included as well as a chapter on Density Functional Theory, which is the underlying method behind all calculations presented in the accompanying papers. Multiple Scattering Theory is also discussed, both in more general terms as well as how it is used in the methods employed to solve the electronic structure problem. One of the methods, the Exact Muffin-Tin Orbital method, is described extensively, with special emphasis on the slope matrix, which energy dependence is investigated together with possible ways to parameterize this dependence. Furthermore, a chapter which discusses different ways to perform calculations for disordered systems is presented, including a description of the Coherent Potential Approximation and the Screened Generalized Perturbation Method. A comparison between the Exact Muffin-Tin Orbital method and the Projector Augmented-Wave method in the case of systems exhibiting both compositional and magnetic disordered is included as well as a case study of the MoRu alloy, where the theoretical and experimental discrepancies are discussed. The thesis is concluded with a short discussion on magnetism, with emphasis on its computational aspects. I further discuss a generalized Heisenberg model and its applications, especially to fcc Fe, and also present an investigation of the competing magnetic structures of FeNi alloys at different concentrations, where both collinear and non-collinear magnetic structures are included. For Invar-concentrations, a spin-flip transition is found and discussed. Lastly, I discuss so-called quantum corrals and possible ways of calculating properties, especially non-collinear magnetism, of such systems within perturbation theory using the force theorem and the Lloyd’s formula.

In the context of the world's increasing environmental challenges and the rise of green consumerism, promoting sustainable consumer behavior is more important than ever. This study aims at extending the understanding of consumers' purchase intention of environmentally friendly cosmetic products. With a theoretical starting point in theories of green promotion and the theory of planned behavior, a total of ten hypotheses and sub-hypotheses were formulated to answer the research question how green promotional cues can be used to affect consumers' beliefs and increase purchase intention. Central concepts in the study’s constructed conceptual framework are intrinsic cues which represent concrete characteristics of a product such as ingredients and formula, and extrinsic cues which are attributes not present within the product itself such as packaging and brand. A quantitative approach using an online survey in an experimental vignette designed questionnaire generated responses from a sample of 325 participants in three treatment groups, and the data was subsequently examined through statistical analysis. The study’s main findings show that intrinsic cues have a stronger influence on purchase intention than extrinsic cues but that extrinsic cues seem to have a stronger influence on consumers’ subjective beliefs. The study provides implications on how cosmetic companies can use the insights generated by the study when developing promotional strategies for green cosmetics.

Green macroalgae represent an attractive source of renewable carbon. Conversion of algal biomass to useful products requires depolymerization of the cell wall polysaccharides cellulose and ulvan. Cellulose saccharification has been widely studied and involves synergistic action of endoglucanases, exoglucanases, and β-glucosidases. The enzymatic depolymerization of ulvan has not received the same attention and additional studies are required in order to fully understand the mechanisms involved in its biodegradation. Synthetic biology offers the possibility of importing modules such as biomass-degrading systems and biofuel producing pathways from different organisms into a genetically tractable host such as Escherichia coli. In this study it was shown that E. coli expressing the glycosidase CHU2268 of Cytophaga hutchinsonii grows well on cello-oligosaccharides such as cellohexaose, and co-expression with the endoglucanase CenA of Cellulomonas fimi allows growth on untreated crystalline cellulose. Moreover, a model for ulvan utilization was built for the first time based on a polysaccharide utilization locus from the alga-associated flavobacterium Formosa agariphila. It was also shown that F. agariphila, is able to grow using biomass from the green macroalga Ulva lactuca as its sole carbon source, and enzymes with ulvanase activity are induced by the presence of this alga in the culture medium. Enzymes for ulvan depolymerization from F. agariphila, including an ulvan lyase, xylanases and rhamnosidases, were cloned using the PaperClip DNA assembly method and expressed in active form in E. coli. Furthermore, a secretion system based on the use of the Antigen 43 was successfully used to secrete an active ulvan lyase using E. coli and ribosome binding sites of different strengths were studied and used to optimize the system. These results represent a first step for the design of a microorganism capable of utilizing green macroalgal biomass for the production of biofuels and other valuable bio-products.

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.

In questa tesi analizzo le funzioni armoniche e le loro fondamentali proprietà. Partendo dal teorema della divergenza, introduco le formule di rappresentazione di Green, da cui deduco le formule di media di superficie e di volume. Utilizzo poi queste ultime per ricavare importanti risultati come: la disuguaglianza di Harnack sui dischi, il teorema di Liouville, il principio del massimo e minimo (forte e debole) e altre importanti proprietà. Le più significative sono la regolarità delle funzioni armoniche, un teorema che stima le derivate e infine l'analiticità.

Il punto centrale della tesi è stato dimostrare il Teorema di Koebe per le funzioni armoniche. È stato necessario partire da alcuni risultati di integrazione in Rn per ricavare identità e formule di rappresentazione per funzioni di classe C2, introdurre le funzioni armoniche e farne quindi una analisi accurata. Tali funzioni sono state caratterizzate tramite le formule di media e messe in relazione con le funzioni olomorfe, per le quali vale una formula simile di rappresentazione.

Oggetto di studio di questa tesi sono le funzioni armoniche. Inizialmente abbiamo introdotto le nozioni principali (definizione di funzione armonica e calcolo esplicito delle funzioni radiali armoniche). Dopo aver enunciato e dimostrato il teorema della divergenza e la prima e seconda identità di Green ci siamo ricavati le formule di rappresentazione di Green. Successivamente, dopo aver calcolato il volume e l'area di bordo di una palla euclidea, abbiamo introdotto le formule di media del Laplaciano. Una loro diretta conseguenza è la Disuguaglianza di Harnack, che abbiamo enunciato e dimostrato inizialmente per una palla e poi generalizzato a un compatto. Abbiamo poi visto un'applicazione di questa disuguaglianza: il teorema di Liouville. Infine abbiamo illustrato il principio del massimo (minimo) forte e del massimo (minimo) debole.

O presente trabalho teve por objetivo avaliar o potencial de parasitismo e eficiência de E. formosa sobre B. tabaci biótipo B em couve, tomate e soja. O tempo de desenvolvimento de ovo a adulto e o número de ninfas de B. tabaci biótipo B foram avaliados em soja, tomate e couve. O número de ninfas parasitadas diariamente e o número total de ninfas parasitadas por fêmeas de E. formosa até sua morte foram avaliados para determinar a capacidade de parasitismo do parasitóide. Foram realizadas liberações de números variáveis de E. formosa para um número fixo de ninfas de B. tabaci biótipo B para avaliar o número ideal de parasitóides por planta. Através dos resultados obtidos, observou-se que a duração de ovo a adulto de B. tabaci biótipo B em tomate (22,03 dias) foi estatisticamente superior a de soja (21,17 dias) e esta última significativamente superior que em couve (19,8 dias) sob as mesmas condições ambientais. O parasitóide E. formosa apresentou preferência por ovipositar no terceiro e quarto ínstares de seus hospedeiros. Comparando-se as três culturas avaliadas verifica-se que a couve apresentou número médio total de ninfas parasitadas superior aos valores obtidos para soja e tomate, que por sua vez não apresentaram diferença entre si. O parasitóide não apresentou diferença em relação à longevidade quando foram oferecidas ninfas de terceiro ou quarto ínstares nas culturas estudadas. Entretanto, verificou-se que para os dois estádios ninfais houve diferença significativa entre as culturas avaliadas. Na couve, a densidade de oito parasitóides por planta resultou em bom controle da praga.The potencial of parasitism and the efficiency of Encarsia formosa on Bemisia tabaci were evaluated on collard green, tomato and soybean plants. The period of developmentof B. tabaci biotype B from egg to adult and the number of nymphs were evaluated on those plants. The ability of parasitism was evaluated by the number of daily parasitized nymphs and the total number of parasitized nymphs per female of E. formosa. The ideal number of parasitoids per plant was evaluated by releasing variable numbers of E. formosa on a fixed number of B. tabaci biotype B nymphs. The results were as follows: the duration of the egg to adult period of B. tabaci biotype B on tomato (22,03 days) was statistically superior to that on soybean (21,17 days), while this last one was significantly superior to that on collard green (19,8 days), under the same environmental conditions; the parasitoid showed preference to oviposit on the third and fourth instars of B. tabaci biotype B nymphs; the number of parasitized nymphs on collard green was higher than those observed on soybean and tomato, whereas the numbers on these last one did not differ; no difference was observed as to the parasitoid longevity when third and fourth instar nymphs were offered on the tested plants; however one observe a significant difference in the mean number of parasitized nymphs; on collard green plants eight parasitoids per plant resulted in a good control of this insect pest.

Resumo: O potencial subutilizado de muitas áreas verdes urbanas e a maneira desinteressante como a Botânica é geralmente tratada em sala de aula foram algumas das questões que motivaram a realização deste trabalho. Seus objetivos centrais foram: (1) fornecer subsídios para o estabelecimento de uma relação mais próxima entre a flora de uma área urbana e seus freqüentadores atuais e potenciais e (2) realizar uma experiência de utilização dessa área, inserindo a dimensão não formal no contexto do ensino formal, numa tentativa de tornar o aprendizado de Botânica mais prazeroso. Foi realizado o levantamento das espécies herbáceas, arbustivas e arbóreas que ocorrem em cinco subáreas da área de estudo ¿ o Parque Taquaral.Foram encontradas 169 espécies; dentre as 157 identificadas até o nível de espécie, 94 são nativas, 62 exóticas e uma híbrido artificial. As informações reunidas acerca das subáreas revelaram que cada uma delas possui, comparativamente, certas características que favoreceriam a realização de atividades ¿ alto número total de espécies, grande quantidade de espécies de pequeno porte, alta concentração de espécies em uma pequena área. Chaves de identificação (uma geral e uma para cada subárea) foram confeccionadas procurando-se utilizar uma linguagem acessível a um público não acadêmico, de forma a poderem ser utilizadas por usuários do Parque ou por planejadores de atividades. A subárea que apresentou maior número de espécies (71) foi utilizada para a realização de uma experiência de ensino de Botânica A atividade de ensino foi realizada junto a duas turmas de 6a série eplanejada em conjunto a com a Professora de Ciências dos mesmos. Princípios da pesquisa-ação embasaram esse processo, no qual se procurou utilizar uma abordagem construtivista. As aulas em sala foram ministradas pela Professora de Ciências, durante as quais as informações foram coletadas por esta autora através de diário de campo e um meio-termo entre observação participante / não participante. A atividade no Parque foi conduzida por esta autora; teve tanto registro fonográfico quanto por escrito por auxiliares de campo. Questionários foram aplicados antes e depois do conjunto de aulas teóricas e atividade de campo. Acertos e desafios se mostraram na análise dessas atividades. Ao mesmo tempo que a participação dos alunos foi estimulada e efetivamente detectada no Parque ¿ na forma de uma ampla gama de comentários, perguntas e atitudes ¿, pôde-se perceber a necessidade de meios que estimulem a concentração da atenção nos temas principais da atividade; apesar da tentativa de abordar conceitos de forma integrada, a fragmentação não foi totalmente superada nessas abordagens. Espera-se que novas experiências venham adaptar, aperfeiçoar e enriquecer a proposta oferecida por este trabalho
Abstract: The underexplored potencial of many green urban areas and the uninteresting way in which Botany is usually teached inside classroom were some of the issues that motivated the accomplishment of this research. Its main objectives were: (1) offer subsidies for the establishment of a closer relationship between the flora of an urban area and its present and potential users and (2) make a experience of utilization of that area, bringing the informal dimension into the context of the formal teaching, in order to try to make the learning process of Botany more pleasant. The survey of the herbaceous, shrub and tree species that occur in five subareas of the study area ¿ the Parque Taquaral ¿ was accomplished. 169 species were found; among the 157 identified until the species level, 94 are native, 62 are exotics and one is an artificial hybrid. The information gathered about the subareas revealed that each of them have, comparatively, certain characteristics that favour the accomplishment of activities ¿ high total number of species, high quantity of small-sized species, high concentration of species in a small area. Identification keys (a general one and one for each subarea) were made, trying to use a language accessible to a non-academic public in a way that they can be used by the Parque users or by activity-planners. The subarea that presented the highest number of species (71) was used for an experience of Botany teaching. The teaching activity was accomplished with two 6th grade classes and planned with their Science teacher. Action-research principles based this process, during which a constructivist approach was tried. The lectures in classroom were given by the Science teacher and the data was collected by the present author by means of participant and non-participant observation and field diary. The activity in the Parque was leaded by the present author; it was tape-recorded and also registered in written form by field assistants. Success and challenges emerged during the analysis of these activities. The participation was stimulated and effectively detected in the Parque ¿ in the form of a vast variety of comments, questions and attitudes ¿, but the need of strategies that stimulate the concentration of the students in the main activities themes could also be noticed; despite it was tried to approach concepts in an integrated way, the fragmentation was not completely overcome in these approaches. It is expected that new experiences adapt, improve and enrich the proposal offered by this research

L'équation de la chaleur est un phénomène macroscopique, émergeant après une limite d'échelle diffusive (en espace et en temps) d'un système d'oscillateurs couplés. Lorsque les interactions entre oscillateurs sont linéaires, l'énergie évolue de manière balistique, et la conductivité thermique est infinie. Certaines non-linéarités doivent donc apparaître au niveau microscopique, si l'on espère observer une diffusion normale. Pour apporter de l'ergodicité, on ajoute à la dynamique déterministe une perturbation stochastique qui conserve l'énergie. En premier lieu nous étudions la dynamique Hamiltonienne d'un système d'oscillateurs linéaires, perturbé par un bruit stochastique dégénéré conservatif. Ce dernier transforme à des temps aléatoires les vitesses en leurs opposées. On montre que l'évolution macroscopique du système est caractérisée par un système parabolique non-linéaire couplé pour les deux lois de conservation du modèle. Ensuite, nous supposons que les oscillateurs évoluent en environnement aléatoire. La perturbation stochastique est très dégénérée, et on prouve que le champ de fluctuations de l'énergie à l'équilibre converge vers un processus d'Ornstein-Uhlenbeck généralisé dirigé par l'équation de la chaleur.Il est désormais connu que les systèmes unidimensionnels présentent une diffusion anormale lorsque le moment total est conservé en plus de l'énergie. Dans une troisième partie, on considère deux perturbations, l'une préservant le moment, l'autre détruisant cette conservation. En faisant décroître l'intensité de la seconde perturbation, on observe une transition de phase entre un régime de diffusion normale et un régime de superdiffusion.

Les mémoires résistives non volatiles basées sur les oxydes (OxRAM) acquièrent récemment un grand intérêt pour leurs performances, ce qui en fait des candidats prometteurs comme mémoire de stockage pour remplacer la technologie flash, et comme mémoires intégrées pour les applications réseau de neurones. Néanmoins, les dispositifs OxRAM émergents présentent encore certains inconvénients, comme la non-uniformité des paramètres de commutation et les défaillances de commutation. Surmonter ces inconvénients exige une compréhension plus profonde des principes de fonctionnement de l’OxRAM, jusqu’à présent pas complètement compris. Ceci peut être réalisé au moyen de simulations textit{ab initio}. Ce travail présente donc une étude approfondie de HfO₂, qui fait partie des matériaux les plus prometteurs pour la construction de dispositifs OxRAM, au moyen de calculs précis des états de quasi-particules (QP). Une étude des propriétés du transport électronique dans les dispositifs OxRAM est également de première importance. Toutefois, cela nécessite un cadre théorique solide et fiable afin de calculer la conductance des jonctions métal/isolant. L’approche standard, basée sur la théorie fonctionnelle de la densité, le formalisme de la fonction de Green et la formule de Landauer, a quelques limites et soucis de fiabilité. Ce travail propose une approche plus fiable basée sur les calculs QP, qui fournissent une structure électronique plus précise pour calculer la conductance, et teste en grande partie cette nouvelle méthode sur différentes jonctions imitant les dispositifs OxRAMResistive non-volatile memories based on oxides (OxRAM) are recently acquiring a wide interest for their performances, which make them promising candidates as storage memories to replace flash technology, and as embedded memories for neural network applications. Nevertheless, emerging OxRAM devices still present some drawbacks, like non-uniformity of switching parameters and switching failures. Overcoming these drawbacks requires a deeper comprehension of the OxRAM working principles, so far not completely understood. This can be achieved by means of textit{ab initio} simulations. Hence this work presents a careful characterization of HfO₂, which is within the most promising materials to build OxRAM devices, by means of accurate quasi-particle (QP) calculations. A study of the electronic transport properties in OxRAM devices is also of primary importance. However, this requires a robust and reliable theoretical framework to compute the conductance of bulk metal/insulator junctions. The standard approach, based on density functional theory, Green function formalism, and Landauer formula, has some limitations and reliability issues. This work proposes a more reliable approach based on QP calculations, which provide a more accurate electronic structure to compute the conductance, and largely tests this new method on different junctions mimicking OxRAM devices

La constatation que les prix des actifs boursiers sautent brusquement a conduit à étudier des modèles de marchés avec sauts. Cette thèse va dans cette direction. On y considère des marchés dirigés par des martingales normales qui ont la propriété de représentation chaotique: les martingales vérifiant une équation de structure déterministe, la martingale d'Azéma, etc. On trouve des stratégies de couverture pour les options européennes, asiatiques et Lookback soit par la formule d'Itô, soit par la formule de Clark-Ocone selon la plus appropriée. L'application du calcul de Malliavin au calcul des Greeks est traitée pour les options asiatiques dans le cas d'un marché dirigé par un processus de Poisson. On traite aussi de couverture dans un modèle à volatilité stochastique avec sauts où le prix de l'actif risqué est dirigé par un processus somme d'un mouvement brownien et d'un processus de Poisson 2-dimensionnels. Le marché est incomplet et il existe une infinité de mesures martingales équivalentes. On minimise l'entropie pour choisir telle mesure. Sous celle-ci on calcule la stratégie minimisant la variance.

Contexte Avec l'augmentation continue du trafic aérien, une refonte des méthodes de planification pour les trajectoires des avions est nécessaire. De nombreuses pistes, telles que les fonctions de navigation, ont été proposées, mais dans le domaine de la gestion du trafic aérien, toute nouvelle méthode doit démontrer sa fiabilité avant de pouvoir être déployée. Objectifs Implémenter des outils permettant de démontrer la robustesse des trajectoires obtenues avec les fonctions de navigation harmoniques aux aléas liés au vent qui ont pour effet de déplacer longitudinalement les avions. Méthodes La variation de Hadamard permet de déterminer la variation de la solution d'une équation différentielle sous une perturbation des bords du domaine. La mise en oeuvre de cette formule de variation nécessite l'implémentation d'une méthode efficace pour le calcul numérique de la fonction de Green. Résultats Nous avons montré dans cette thèse qu'il est possible d'obtenir la fonction de Green, ainsi que ses dérivées, de façon semi-analytique. De plus, les valeurs obtenues par cette méthode pour la fonction de Green peuvent être utilisées dans le calcul de la variation de Hadamard. Conclusions L'utilisation de cette fonction de Green semi-analytique pour le calcul de la variation de Hadamard permet de prendre en compte des incertitudes sur la position des obstacles. Des pistes d'amélioration de cette méthode basée sur la fonction de Hadamard sont également proposées, notamment pour optimiser le temps de calcul de la variation et pour améliorer la précision des résultatsContext As air traffic continues to increase, new aircraft trajectory plannification methods need to be implemented. Navigation functions have been implemented to this end, but their reliability in an uncertain environment is yet to be demonstrated. Aims Implementing new tools based on the Hadamard variational formula to take into account the uncertainties on the longitudinal position of aircraft when computing the navigation function. Methods The Hadamard variation makes it possible to assess the effect of a domain boundary variation on the trajectories computed using harmonic navigation functions. Using this variational formula requires the developpment of an efficient method to numerically compute the Green's function. Results We demonstrate in this thesis that it is possible to numerically determine the Green's function and its derivatives with a semi-analytical method. Furthermore, the Green's function determined in this manner can be used to compute the Hadamard variational formula. Conclusions This semi-analytical Green's function can be used to compute the Hadamard variational formula and makes it possible to account for uncertainties on the position of obstacles. We also give some leads on how to improve this method based on the Hadamard variational formula, most notably on how to reduce computation time and improve accuracy

Questo lavoro di tesi ha come argomento principale la proprietà di media delle funzioni armoniche. Il primo Capitolo è dedicato allo studio delle funzioni armoniche: in particolare, si dà la dimostrazione delle formule di media di superficie e di volume, si dimostra che esse caratterizzano le funzioni armoniche, e, infine, si dimostra che vale il principio del massimo. Nel secondo Capitolo viene trattato il problema di Dirichlet per l'operatore di Laplace: si introduce la funzione di Green, si costruisce il nucleo di Poisson per la palla e si dimostra che, a partire da esso, è possibile costruire una soluzione classica per il problema nella palla. Nel terzo Capitolo, si danno due stime di stabilità delle formule di media di volume: se un aperto di misura finita e un suo punto verificano "quasi'' la formula della media di volume per ogni funzione armonica, allora tale aperto è "quasi'' una palla centrata in quel punto. Da ciò segue immediatamente la rigidità della formula, ovvero il Teorema di Kuran: le palle sono gli unici aperti di misura finita che verificano la formula della media di volume per ogni funzione armonica. L'ultimo Capitolo è dedicato alla rigidità della formula della media di superficie. Sotto alcune ipotesi di regolarità, infatti, è possibile dimostrare che le sfere sono le uniche superfici che verificano tale formula per ogni funzione armonica. Quest'ultimo notevole risultato è dovuto a G. Fichera.

This study examines phrase and larger formal structures in the first movement of Leo Brouwer’s Elegio de la Danza (1964), a work that draws on tonal and post-tonal traditions. By adapting key features of the tonal motive, as described by Douglass Green, and the tonal period, as proposed by Green and William Caplin, the model seeks to provide a tool for the discussion of phrases and larger forms in Brouwer’s work. An analysis of primary parameters, such as melody, harmony, and rhythm, provides the means to discuss how the composer articulates beginnings and endings of statements and responses, which are then grouped into antecedent and consequent phrases. These periods articulate large-scale sections, which outline a ternary formal design. Secondary parameters (dynamics, tempo markings, instrumental markings) further contribute to the identification of formal structures in Brouwer’s work.

L'objectif principal de cette thèse est de généraliser les multizetas au cas où le corps de base Q est remplacé par un corps de nombres quelconque. La motivation derrière cette construction vient des travaux de A. Goncharov sur les corrélateurs de Hodge et de la philosophie plectique de J. Nekovar et A. Scholl. On commence par la construction des fonctions de Green plectiques supérieures. Hecke a prouvé que l'intégration d'une série d'Eisenstein appropriée sur le groupe de classes des idèles du corps de nombres donné, multipliée par un caractère du groupe des classes des idèles, est équale à la fonction L associée à ce caractère. Remplacant la série d'Eisenstein par les fonctions de Green plectiques supérieures, une intégration similaire donne des nouveaux résultats, qui généralisent les multizetas classiques et les multi-polylogarithmes. D'après le principe plectique, un sous-groupe de l'anneau des entiers du corps de nombres donné joue un rôle essentiel dans ces travauxThe principal objective of this thesis is to generalize multiple zeta values to the case when the ground field Q is replaced by an arbitrary number field. The motivation behind the construction comes from the work of A. Goncharov on Hodge correlators and the plectic philosophy of J. Nekovar and A. Scholl. We start by constructing the higher plectic Green functions. Hecke once proved that the integral of the restriction of a suitable Eisenstein series over $\mathbb{Q}$ to the idele class group of a given number field multipled an idele class character of finite order is equal to the L-function of this charator. By replacing Eisenstein seris with our higher plectic Green functions, a similar integration gives new results, which give the generalization of classical multiple zeta values and multiple polyloarithms. According to the plectic principle, a non-trivial subgroup of the ring of integers of a given number field plays an essential role in this work

Os problemas socioambientais fundamentam-se em uma crise de valores, onde a incorporação de atitudes pro ambientais é primordial. Nesse sentido, os processos educativos são importantes para impulsionar as transformações necessárias para a sobrevivência da sociedade e podem ser desenvolvidos tanto na educação formal quanto na educação não formal. Há a necessidade de trazer conhecimento e de sensibilizar os jovens quanto à importância das questões ambientais, contribuindo para que desenvolvam um posicionamento crítico face à crise detectada. A Educomunicação, que tem como um de seus compromissos a produção participativa de conteúdo, apresenta-se como uma alternativa de ferramenta para a realização de intervenções que favoreçam a preservação dos recursos naturais. Esta pesquisa foi realizada em Instituto de Assistência Social de Curitiba, com 52 jovens de idades entre 14 e 17 anos em seu período de contraturno escolar. O objetivo da proposta visou desenvolver, aplicar e avaliar metodologias de educação ambiental, utilizando ferramentas de Educomunicação socioambiental para a promoção de informação e sensibilização quanto a questão dos resíduos sólidos nos corpos d’água. Foi desenvolvida a partir de uma abordagem mista (quantitativa e qualitativa), utilizando os princípios metodológicos da pesquisa-ação, através de um diagnóstico inicial de percepção ambiental, nível de conhecimentos e atitudes referentes ao tema. Como também, a análise de seus resultados para planejamento e elaboração das atividades respeitando uma sequência lógica para apreensão de novos conhecimentos. As intervenções abordaram teorias e práticas sendo denominadas oficinas. Estas, utilizaram procedimentos adequados para suas realizações que consistiram em palestras, discussões, atividades de campo, programas de rádio, registro por fotografias e filmagens, criação de páginas na rede social e evento. Os materiais textuais e audiovisuais produzidos serviram como subsídios para as produções de Educomunicação socioambiental visando instigar a percepção ambiental do jovem e da sociedade sobre a poluição de rios por resíduos sólidos. As informações e conhecimentos adquiridos durante o percurso do desenvolvimento, foram o suporte para a compilação dos saberes sobre os efeitos da interferência humana nos sistemas aquáticos, e, de sensibilização para inserção de atitudes sustentáveis, como por exemplo, a separação seletiva de resíduos sólidos e seu correto descarte. Sendo todo o processo desenvolvido através do diálogo, participação, da expressão e criatividade dos sujeitos envolvidos na pesquisa.Environmental problems are founded in a crisis of values, where the incorporation of environmental attitudes is an urgent need. In this sense the educational processes are essential to boost the transformations necessary to the survival of society and these processes can occur both in formal education and in non-formal education. No need to bring knowledge and raise awareness among young people about the importance of environmental issues, helping to develop a critical attitude before the socio-environmental crisis. The Educommunication that has as one of its commitments participative content production, is presented as a possible tool for the realization of social and environmental interventions.This survey was conducted with 52 people aged between 14 and 17 years during their period of school hours in the Institute of Social Assistance located in the city of Curitiba, Parana state. The research objective aimed to develop, implement and evaluate methods of education, using tools of environmental educational and communication. Such activity was focused on promoting information and awareness related to the impact of solid waste on water bodies. It was developed from a mixed approach (quantitative and qualitative), the methodological principles of action research through an initial diagnosis of environmental perception, level of knowledge and attitudes related to the subject. The analysis of such results was utilized for planning and preparation of activities with a logical construction of knowledge. The interventions addressed theories and practices known as “Oficinas”. This strategy used proper procedures that consisted of lectures, discussions, field activities, radio programs, photographs and footage, events and the creation of pages on social networking to achieve the aimed results. All textual and audiovisual material produced served as subsidies for production of environmental educational communication with the objective of instilling environmental awareness on young pelople and society about pollution of rivers by solid residues. The information and knowledge gained during the research has supported the compilation of knowledge on the effects of human interference in aquatic systems as well as on raising awareness of sustainable attitudes. Thus, the whole process has enabled the dialogue, participation, expression, creativity and reasoning of the subjects involved in the research.

CAPES; EMATERUm dos maiores problemas ambientais da população brasileira é a falta de tratamento de esgoto, principalmente em comunidades rurais e de baixa renda. O desenvolvimento de tecnologias para saneamento eficientes e de baixo custo precisam ser desenvolvidas para atender a população desfavorecida deste serviço básico. Nesse trabalho foi proposta a implantação de uma tecnologia denominada wetlands construídos, também conhecida por Estação de Tratamento de Esgoto por Zona de Raízes – ETEZR. O objetivo do trabalho foi desenvolver uma proposta de Educação Ambiental não formal para o saneamento, utilizando metodologias de sensibilização para os moradores e implantação desta tecnologia ETEZR na comunidade rural da Colônia Mergulhão em São José dos Pinhais - PR. Com o apoio técnico do Instituto Paranaense de Assistência Técnica e Extensão Rural – EMATER e da Universidade Tecnológica Federal do Paraná – UTFPR, foram implantadas 5 ETEZR na colônia, por meio de 3 Oficinas teóricas e práticas, nas quais participaram no total 67 pessoas da comunidade, 5 técnicos da EMATER e 13 da Prefeitura Municipal do Município. Após 4 meses da implantação foram realizadas 2 coletas do efluente bruto e tratado para analisar parâmetros físico-químicos e biológicos. Os resultados avaliados pelos parâmetros químicos DBO, DQO, fósforo, nitrogênio amoniacal comparando esgoto bruto e tratado, demonstram que as ETEZR são eficientes no tratamento de esgoto.Nas 5 estações a eficiência mínima e máxima entre os parâmetros básicos analisados foram de 52,2 a 95,5% para a DBO; 47 a 94,5% para a DQO; 21,5 a 96% para fósforo; 30 a 98% para nitrogênio amoniacal. Os óleos e graxas, e a série de sólidos também obtiveram significativa redução em seus valores quando comparados o esgoto bruto e o esgoto tratado, e os parâmetros biológicos avaliados por meio dos coliformes apresentaram uma redução entre 80 a 99%. Com a aplicação do processo de Educação Ambiental voltado ao saneamento foi possível avaliar a percepção da população para a aceitação da tecnologia de saneamento ambiental utilizando as ETEZR, compreender as necessidades e conceitos de saneamento para a comunidade. : Esta pesquisa avaliou o desenvolvimento da metodologia aplicada pela Educação Ambiental não formal, a fim de proporcionar subsídios ao processo do plano de saneamento rural para o município.
One of the biggest environmental problems of the population is the lack of sewage treatment, especially in rural communities and low-income. The development of technologies for efficient, low-cost sanitation need to be developed to meet the disadvantaged people of this basic service. This work was the implementation proposal of a technology called constructed wetlands, also known as Wastewater Treatment Plant for Roots Zone - ETEZR. The objective was to develop a non- formal environmental education proposal for redevelopment, using outreach methods for residents and deployment of this technology ETEZR in the rural community of Cologne Grebe in Sao Jose dos Pinhais - PR. With technical support from the Paranaense Technical Assistance and Rural Extension Institute -EMATER and the Federal Technological University of Paraná - UTFPR, 5 ETEZR were deployed in the colony through three theoretical and practical workshops, which involved total 67 people from the community 5 technicians EMATER and 13 of the Municipal Town Hall. Após4 months of implementation were carried out two collections of raw wastewater and treated to analyze physical, chemical and biological parameters. The results evaluated by chemical parameters BOD, COD, phosphorus, ammonia nitrogen comparing raw and treated sewage, demonstrate that ETEZR are effective in the treatment of sewage. 5 Seasons minimum and maximum efficiency between the basic parameters analyzed were 52.2 to 95.5% for BOD; 47 to 94.5% for COD; 21.5 to 96% phosphorus; 30-98% for ammonia nitrogen. Oils and greases, and a series of solid also achieved a significant reduction in their values when comparing the raw sewage and treated sewage, and biological parameters evaluated by means of coliforms showed a reduction of 80 to 99%. With the implementation of environmental education process aimed sanitation was possible to evaluate the perception of the population to accept the environmental sanitation technology using the ETEZR, understand the needs and sanitation concepts for the community. This research evaluated the development of the methodology applied by the non-formal environmental education in order to provide subsidies for rural sanitation plan process for the municipality.

The thesis informs a reader about problems of establishing new/small political parties and their activities in Czech Parliament during the period of 2002 -- 2010. The surprising and unexpected results of Chamber of Desputies election that took place in May 2010 and brought considerable transformation of contemporary political establishment in Czech republic, represented the main impulse for writing this thesis. The aim of the thesis was to find out the size of political market openness for new/small political parties during the period of 2002-2010 and simultaneously evaluate what kind of position and substance these new/small political subjects in the political market have. A content of thesis is divided into two main parts. The first part is focused on theoretical theme and includes four chapters. There are mentioned mainly the issues of new/small political parties' definitions, the role of relevant parties in proportional representation systems and also some of the most important attempts of electoral reforms. The second part includes the final chapter that is focused on analysis of the factors that had influence on increase or decrease in chances of new/small parties to be successful in Chamber of Desputies elections from 2002 and thus become the part of political establishment. The fundamental questions were: How have the new/small political parties built up in that period of 2002-2010 and under what circumstances have they become the part of political establishment.

Due to urban development, green space is replaced by impervious pavement that disturbs the urban water cycle. To mitigate the negative effect brought by urbanization, green roof has been widely accepted as one of methods to achieve this goal. Determination of irrigation water requirement for green roof is necessary. Therefore, estimation of evapotranspiration is required for determining water requirement of green roof and provides as the base for storage volume determination of rainwater harvesting system. For most research in evapotranspiration, the application mostly focused on irrigation water requirement and rare in that of green roof aspect. The Penman formula was complicated and also widely used in irrigation water requirement estimation but it required more parameters that are not available in some locations. The purpose of this research was to select some evapotranspiration formulas with less parameter and compare with the observed data to determine the proper parameter values for local use. Firstly, this research extended the observed evapotranspiration data by using the Penman formula and evapotranspiration modified coefficient (K). Then the theoretical evapotranspiration values for daily and monthly estimated by the methods of Blancy-Criddle, Hargreaves and Samani and Kharrufa were compared with that of extended observation values. It was found that daily and monthly vales estimated by those three formulas were under-estimated compared to observed data. Secondly, the fitness coefficient would be used to evaluate the goodness of parameters among formulas that would decrease the difference between observed and estimated values. The results showed that the Hargreaves and Samani formula was superior to other two formulas in daily estimation of evapotranspiration values. Because of sunshine percentage variation, both Blancy-Criddle and Samani formulas could not obtain the certain precision even with parameters adjustments. Therefore, the Hargreaves and Samani formula was recommended for the areas with limited meteorological and hydrological data.

Rising environmental awareness has made the concept of green consumption become more and more popular. The endless emergence of food safety incidents has made infant food safety more and more concerning. It has also boosted the booming organic infant formula market. However, there are many brands of organic infant formula, which gives consumers a difficult choice and brings consumer confusion. Additionally, the lifestyle of each consumer is different. To understand existing and potential organic infant formula consumers, the food-related lifestyle model is suitable as a tool to group consumers into several types. The purpose of this study is to explore the differences between consumer confusion and the intention of green consumption among consumers of different food-related lifestyles and the relationship between consumer confusion and the intention of green consumption. This study issued web-based questionnaires to consumers who participate in Internet forum or virtual community about parent-child or parenting. The lower age limit was 23. 409 Questionnaires were distributed and 381 effective questionnaires were collected. The analytical methods included description statistics, exploratory factor analysis, cluster analysis, one-way analysis of variance, and correlation analysis. The conclusions of the study are as follows: 1. The consumers were grouped into three types: unfamiliar with food, attach importance to texture and pragmatic. 2. There was no significant difference in the level of consumer confusion among different types of consumers. 3. There were differences in the intention of green consumption in different types of consumers. 4. There is a positive relationship between the intention of green consumption and consumer confusion.
