Dans cette thèse, nous proposons de décrire la dynamique d'un film liquide mince entraîné par un écoulement gazeux. Dans une première partie, nous montrons comment écrire des modèles à une équation, sur la hauteur, ou à deux équations, sur la hauteur et le débit, à partir des équations de Navier-Stokes en utilisant la méthode des développements asymptotiques. Nous étudions alors les propriétés des systèmes ainsi obtenus. Dans la deuxième partie, nous utilisons la même méthode pour étendre les modèles aux cas des écoulements sur une topographie quelconque mais aussi aux écoulements bi-couches à surface libre et les écoulements de deux fluides entre deux plaques. La dernière partie consiste en une étude numérique d'un écoulement cisaillé à l'aide du code SLOSH et d'une application d'un des modèles trouvé dans le cas de deux fluides superposés à surfaces libres.

This thesis applies the ab initio techniques of computational chemistry to studies of molecular clusters containing covalent (strong) or van der Waals (weak) bonds formed in chemistry and biochemistry in the temperature range 10-300 K. Van derWaals complexes with an enthalpy of formation from reactants of less than 25 kJ mol-1 and covalent clusters are described in this thesis. The first group of van der Waals complexes involved the molecule carbon monoxide that possesses a small permanent dipole that could lead to dipole - induced dipole interaction and dipole - dipole interaction with another reactant in addition to dispersion. The substrates investigated were methanimine and cyanogen where endergonic unstable molecules were formed, and the clustering of carbon monoxideon a porphin surface leading to the formation of carbon - carbon fragments. TheFaraday effect was invoked to suggest that this was the original method by which thechirality of the D-sugars was selected. Coordination of imino-compounds on thesame surface involving induction and electrostatic interactions could lead to the preferential formation of L-aziridones, hydrolysable to L-amino-acids.The preferred formation of D-ribose, and the more stable D-2-deoxyribose, andnucleotides polymerisable to deoxyribonucleic acids was described. The second group of van der Waals complexes involved the polymerisation of acetylene molecules, to di- and tri-acetylene complexes where the exchange interaction involved the quadrupole moment of the acetylene radical reacting with acetylene or diacetylene. The reaction of carbon monoxide was extended to include its interaction with diacetylene. The entire potential energy surface for the interaction with diacetylene was investigated. The reaction was shown to be endergonic to produce a reactive species, here postulated to rearrange with a reasonable activation energy toform an aldehyde. The energetics of the formation of diacetylene, triacetylene andhigher polymers was briefly investigated. The reactivity of the acetylene polymeraldehydes with other substrates was briefly investigated. This work has apparently laid a firm basis both, qualitative and quantitative, tounderstand some of the weakest interactions in nature involving the simplest ofreactions that have been important in atmospheric chemistry.

In this dissertation, the accuracy and reliability of non-linear finite element computations in application to surgical simulation is evaluated. The evaluation is performed through comparison between the experiment and finite element analysis of indentation of soft tissue phantom and human brain phantom. The evaluation is done in terms of the forces acting on the cylindrical Aluminium indenter and deformation of the phantoms due to these forces. The deformation of the phantoms is measured by tracking 3D motions of X-ray opaque markers implanted in the direct neighbourhood under the indenter using a custom-made biplane X-ray image intensifiers (XRII) system. The phantoms are made of Sylgard® 527 gel to simulate the hyperelastic constitutive behaviour of the brain tissue. The phantoms are prepared layer by layer to facilitate the implantation of the X-ray opaque markers. The modelling of soft tissue phantom indentation and human brain phantom indentation is performed using the ABAQUSTM/Standard finite element solver. Realistic geometry model of the human brain phantom obtained from Magnetic Resonance images is used. Specific constitutive properties of the phantom layers determined through uniaxial compression tests are used in the model. The models accurately predict the indentation force-displacement relations and marker displacements in both soft tissue phantom indentation and human brain phantom indentation. Good agreement between the experimental and modelling results verifies the reliability and accuracy of the finite element analysis techniques used in this study and confirms the predictive power of these techniques in application to surgical simulation.

Les électrolyseurs à membrane échangeuse de protons basse pression (E-PEMs) apparaissent comme une solution efficace et durable pour la production d’hydrogène. Cette technologie pourrait permettre de pallier l’intermittence des énergies renouvelables (notamment solaire et éolien) en convertissant l’énergie électrique produite en énergie chimique (hydrogène). Durant ces travaux de thèse, trois aspects ont été développés : une approche analytique, une approche numérique, ainsi que approche expérimentale. Ces trois approches ont permis de comprendre l’influence du mélange bi-phasique eau/oxygène à l’anode du système sur les performances électrochimiques des E-PEMS ainsi que déterminer les paramètres opérationnels et intrinsèques qui impactent les performances des E-PEMs. À propos de l'approche expérimentale, des mesures d'impédance électrochimique ainsi que des courbes de polarisation ont été réalisées sur deux différentes cellules d'électrolyseurs de type PEM basse pression (la cellule ITW power de l'Electrochimical innovation Lab (UCL) et la cellule réversible Q-URFC du Laboratoire d'Énergétique, d'Électronique et Procédés (LE2P). À propos de la modélisation numérique, Le modèle expérimentale conjugue une approche multi-échelle macroscopique 2D et mésoscopique 1D. Ce modèle prend en compte le transfert de matière, le transfert de chaleur, les réactions électrochimiques anodique et cathodique et le transfert de charges présents dans le cœur des E-PEMs. D’un point de vue mésoscopique, une attention particulière a été portée sur l’influence des régimes bi-phasiques anodiques (régime de bulles coalescées (BC régime) et régime de bulles non coalescées (NCB régime) sur le transfert de matière à l’anode et sur l’humidification de la membrane. Ces travaux démontrent et confirment l’hypothèse que la transition du NCB régime vers le CB régime augmente le transfert de matière anodique, diminue la résistance ohmique de la membrane et améliore l’efficacité des E-PEMs. À propos de la modèle analytique, l’étude analytique explore une approche adimensionnelle de l'assemblage membrane électrode (AME) en régime stationnaire et isotherme. À l’échelle locale, en 1D, les équations prises en compte sont la conservation du courant dans l’AME, les réactions électrochimiques au sein des couches actives et le transfert de matière à travers la membrane. La résolution a permis d’obtenir des expressions analytiques des surtensions aux électrodes, de la chute ohmique et de la teneur en eau dans la membrane. L’approche adimensionnelle a permis de quantifier analytiquement les sources d’irréversibilités (chute ohmique, surtensions d’activations anodique et cathodique, et de la surtension induite par le bouchonnement des canaux anodiques) respectivement pour les faibles densités de courant, les moyennes densités de courant et les hautes densités de courant. En outre, ce modèle analytique peut être implémenté dans une boucle de contrôle commande. Ces travaux de thèse proposent une contribution à la compréhension du fonctionnement des E-PEMs basse pression en général, et en particulier de l'impact des régimes bi-phasiques sur leurs performances électro-chimiques. / Based on proton conduction of polymeric electrolyte membrane (PEM) technology, the water electrolysis (PEMWE) offers an interesting solution for efficiency hydrogen production. During the electrolysis process of water in PEMWE, the anodic side is the place where the water is splitting into oxygen, protons and electrons. The aim of this study is to recognize the link between two-phase flows (anode side) and cell performance under low pressure conditions. We have developed three approaches: the analytical approach and the numerical approach validated by the experimental data. For the numerical model, we have developed a two-dimensional stationary PEMWE model that takes into account electro-chemical reaction, mass transfer (bubbly flow), heat transfer and charges balance through the Membrane Electrodes Assembly (MEA). In order to take into account the changing electrical behavior, our model combines two scales of descriptions: at microscale within anodic active layer and MEA scale. The water management at both scales is strongly linked to the slug flow regime or the bubbly flow regime. Therefore, water content close to active surface areas depends on two-phase flow regimes. Our simulation results demonstrate that the transition from bubble to slug flow in the channel is associated with improvement in mass transport, a reduction of the ohmic resistance and an enhancement of the PEMWE efficiency. Regarding the analytical model, we have developed a one-dimensional stationary isothermal PEMWE model that takes into account electro-chemical reaction, mass transfer and charges balance through the Membrane Electrodes Assembly (MEA). The analytical approach permit to obtain mathematical solution of the activation overpotential, the ohmic losses and the bubbles overpotential respectively for the low current density, the middle current density and the high current density. This approach quantify the total overpotential of the cell, function of the operational and intrinsic numbers. In terms of perspective, the analytical model could be used for the diagnostic of the electrolyzer PEM.

[pt] A teoria da prova tradicional da lógica proposicional trata provas cujos tamanhos podem ser demasiado grandes. Estudos teóricos de prova descobriram diferenças exponenciais entre provas normais ou livres de corte e suas respectivas provas não-normais. Assim, o uso de grafos-de-prova, ao invés de árvores ou listas, para representar provas está se tornando mais popular entre teóricos da prova. Os grafos-de-prova servem como uma forma de proporcionar uma melhor simetria para a semântica de provas e uma maneira de estudar a complexidade das provas proposicionais. O objetivo deste trabalho é reduzir o peso/tamanho de deduções. Apresentamos formalismos de grafos de prova que visam capturar a estrutura lógica de uma dedução e uma forma de facilitar a visualização das propriedades. A vantagem destes formalismos é que as fórmulas e sub-deduções em dedução natural, preservadas na estrutura de grafo, podem ser compartilhadas eliminando sub-deduções desnecessárias resultando na prova reduzida. Neste trabalho, damos uma definição precisa de grafos de prova para a lógica puramente implicacional, logo estendemos esse resultado para a lógica proposicional completa e mostramos como reduzir (eliminando fórmulas máximas) essas representações de tal forma que um teorema de normalização pode ser provado através da contagem do número de fórmulas máximas na derivação original. A normalização forte será uma consequência direta desta normalização, uma vez que qualquer redução diminui as medidas correspondentes da complexidade da derivação. Continuando com o nosso objetivo de estudar a complexidade das provas, a abordagem atual também fornece representações de grafo para lógica de primeira ordem, a inferência profunda e lógica bi-intuitionista. / [en] Traditional proof theory of Propositional Logic deals with proofs which size can be huge. Proof theoretical studies discovered exponential gaps between normal or cut free proofs and their respective non-normal proofs. Thus, the use of proof-graphs, instead of trees or lists, for representing proofs is getting popular among proof-theoreticians. Proof-graphs serve as a way to provide a better symmetry to the semantics of proofs and a way to study complexity of propositional proofs and to provide more efficient theorem provers, concerning size of propositional proofs. The aim of this work is to reduce the weight/size of deductions. We present formalisms of proof-graphs that are intended to capture the logical structure of a deduction and a way to facilitate the visualization. The advantage of these formalisms is that formulas and subdeductions in Natural Deduction, preserved in the graph structure, can be shared deleting unnecessary sub-deductions resulting in the reduced proof. In this work, we give a precise definition of proof-graphs for purely implicational logic, then we extend this result to full propositional logic and show how to reduce (eliminating maximal formulas) these representations such that a normalization theorem can be proved by counting the number of maximal formulas in the original derivation. The strong normalization will be a direct consequence of such normalization, since that any reduction decreases the corresponding measures of derivation complexity. Continuing with our aim of studying the complexity of proofs, the current approach also give graph representations for first order logic, deep inference and bi-intuitionistic logic.

This thesis operates, unashamedly, from the premise that every act of criticism involves a self-reflexive gesture of one's own concerns and ideological imprintings. For this reason Chapter One establishes the writer's own involvement - both autobiographical and theoretical - in notions of male rage and the 'working through' of these concerns. Chapter Two conducts an overview of male rage and the extant systemic literature on the subject. It sets out the various positions on the subject and posits the importance of gender (over generation) in the praxis of therapy. Furthermore, it explores the possibility that the male is equally, but differently, troubled by the hegemonic forces of patriarchy as is the woman. Without diminishing the legitimacy of the woman's experience in the face of male rage, the argument is forwarded that the male is caught in a similar struggle but without the feminine articulatory resources. This chapter details the lack of male power in the face of his supposed muscular omnipotence. Seminal analytic approaches to the question of gender are raised in Chapter Three. Working through Freud, Klein, Lacan and Masters and Johnson an attempt is made to plot the 'evolution' of the feminine and the masculine. Central to this debate is the bi-polarization of gender relations within the same sex (biology/construction) and without (phallic/vaginal, clitoral, passive/active). What emerges is that femininity is bi-focal and that the woman has more resources at her disposal that hitherto acknowledged. While the woman is always double - as both clitoral and vaginal, as lover and mother- it appears that male sexuality is far more precarious than generally perceived. It is this dis-ease on the part of the male that translates itself into envy and, with it, the need to denigrate and belittle woman as the object of that envy. In Chapter 4 an attempt is made to overlap the seemingly divergent fields of analytic and systemic methodologies via the involvement of the therapist in the eco-system of analysis. The substantial role of the therapist -- and the coercive forces placed on him/her by the couple -- is used to modify Elkaim's model and to introduce the need for a telling of the particular stories that concentrate on the unique narratives of the warring couple rather than the patriarchal regime under which these stories are constrained. Before encountering these narratives an essay is made at establishing a methodology of sorts. Newton's scientific formulations are used in order to question the binary opposition that has been, historically, established between quantitative (male) and qualitative (female) methodologies. In the process of questioning this binary opposition it becomes clear that any form of objectifying approach constitutes a refuge from the messiness that is intrinsic to the therapeutic process. The experimental methodology that is posited is precisely one that engages in the narratives of male violence - four extracts are considered, each exposing different articulations of male violence. The question of female subjectivity (and the attendant power of the sorority) is returned to in light of these stories. Central to this section is the notion that male subjectivity is far more convoluted - perhaps more that the feminine counterpart - than initially conceived. The original identification with the (m)other forever displaces him in that the later identification with the father remains distant and contrived. For the purposes of maintaining the dialogic nature of this work, a feminist appraisal of the rage narratives concludes the thesis. Don Quixote is used, by way of an Epilogue, to offer three representations of male subjectivity and to look towards alternative subject positions for the male under patriarchy. / Psychology / D.Litt. et Phil.

Les changements des connections neuronales interviendraient dans la formation de la mémoire. J’ai développé de nouvelles approches basées sur l’imagerie photonique pour étudier (i) les interactions entre les microglies et les épines dendritiques, et (ii) le renouvellement des épines dans l’hippocampe in vivo. Ces deux phénomènes contribueraient au remodelage des circuits synaptiques intervenant dans la mémoire. (i) Les microglies sont impliquées dans de nouvelles fonctions en condition saine. J’ai examiné l’effet de la plasticité synaptique sur la dynamique morphologique des microglies, et sur leur interaction avec les épines. En combinant l’électrophysiologie et l’imagerie bi-photonique dans des tranches aigües de souris transgéniques, je démontre que la microglie intensifie son interaction physique avec les épines. Ainsi pour continuer l’étude de ces interactions et leur impact fonctionnel plus précisément, j’ai optimisé l’imagerie STED dans des tranches aigües. (ii) La plasticité structurale des épines est cruciale pour la mémoire, mais les connaissances à ce sujet dans l’hippocampe in vivo restent limitées. J’ai donc établi une technique d’imagerie chronique STED in vivo pour visualiser les épines dans l’hippocampe. Cette approche a révélé une densité double de celle reportée précédemment à l’aide de la microscopie bi-photonique. De plus j’ai observé un renouvellement des épines de 40% en 5 jours, représentant un taux important de remodelage synaptique dans l’hippocampe. Les approches d’imagerie super-résolutive permettent l’étude des interactions microglie-épine, et du renouvellement des épines hippocampiques avec une résolution inédite chez la souris vivante. / Activity-dependent changes in neuronal connectivity are thought to underlie learning and memory. I developed and applied novel high-resolution imaging-based approaches to study (i) microglia-spine interactions and (ii) the turnover of dendritic spines in the mouse hippocampus, which are both thought to contribute to the remodeling of synaptic circuits underlying memory formation. (i) Microglia have been implicated in a variety of novel tasks beyond their classic immune defensive roles. I examined the effect of synaptic plasticity on microglial morphological dynamics and interactions with spines, using a combination of electrophysiology and two-photon microscopy in acute brain slices. I demonstrated that microglia intensify their physical interactions with spines after the induction of hippocampal synaptic plasticity. To study these interactions and their functional impact in greater detail, I optimized and applied time-lapse STED imaging in acute brain slices. (ii) Spine structural plasticity is thought to underpin memory formation. Yet, we know very little about it in the hippocampus in vivo, which is the archetypical memory center of the mammalian brain. I established chronic in vivo STED imaging of hippocampal spines in the living mouse using a modified cranial window technique. The super-resolution approach revealed a spine density that was two times higher than reported in the two-photon literature, and a spine turnover of 40% over 5 days, indicating a high level of structural remodeling of hippocampal synaptic circuits. The developed super-resolution imaging approaches enable the examination of microglia-synapse interactions and dendritic spines with unprecedented resolution in the living brain (tissue).

Parmi les approches possibles pour réaliser des sources térahertz dans la gamme0,2 - 2 THz, nous nous sommes intéressés à la voie optoélectronique qui consiste à générerl’onde térahertz par le photomélange de deux ondes lasers à des fréquences optiques. Letravail présenté dans cette thèse concerne l’étude de lasers bi-fréquence capables d’émettreles deux ondes requises simultanément. Nous commençons par développer un modèlethéorique décrivant la compétition de gain entre les modes laser grâce au calcul de différentscoefficients de couplage. Sur le plan expérimental, nous montrons tout d’abord qu’endésalignant légèrement un des miroirs de la cavité laser, il est possible d’obtenir un régimestable d’émission sur deux fréquences pourtant en compétition dans le milieu à gain, ici uncristal dopé néodyme. Nous nous intéressons ensuite au régime impulsionnel et montronsque les impulsions peuvent être synchronisées grâce à l’action d’un laser externe. Enfin, leprocessus de photomélange a été réalisé et des ondes électromagnétiques ont été généréesdans le domaine des radio-fréquences autour de 20 GHz. / Among the possible solutions to build terahertz sources in the 0,2 - 2 THz range,we studied the optoelectronic way consisting in the generation of a terahertz wave by photomixingtwo laser waves at optical frequencies. The work presented in this PhD concernsthe study of dual-frequency lasers able to emit the two required waves simultaneously.We begin by developing a theoretical model describing the gain competition between thelaser modes by calculating different coupling coefficients. Experimentally, we first showthat a slight misalignment of the output mirror of the laser cavity allows to obtain a stableemission at two frequencies competing in the gain medium, which is a neodymium-dopedcrystal. Then, we focus on the pulsed regime and we show that the pulses can be synchronizedby the action of an external laser. Finally, the photomixing process has been achievedand electromagnetic waves have been generated in the radio frequencies range around 20GHz.

Alors que la demande en électronique haute puissance et haute fréquence ne fait qu’augmenter, les semi-conducteurs classiques montrent leurs limites. Des approches basées soit sur des nouvelles architectures ou sur des matériaux à large bande interdite devraient permettre de les dépasser. Le diamant, avec ses propriétés exceptionnelles, semble être le semi-conducteur ultime pour répondre à ces attentes. Néanmoins, il souffre aussi de certaines limitations, en particulier d’une forte énergie d’ionisation du dopant de type p (bore) qui se traduit par une faible concentration de porteurs libres à la température ambiante. Des solutions innovantes s'appuyant sur un gaz 2D et /ou l’effet de champ ont été imaginées pour résoudre ce problème. Ce travail est axé sur deux de ces solutions : i) le diamant delta dopé au bore qui consiste en une couche fortement dopée entre deux couches intrinsèques, afin d’obtenir une conduction combinant une grande mobilité avec une grande concentration de porteurs et ii) le transistor à effet de champ métal oxide semiconducteur( MOSFET ), où l’état « on » et l’état « off » du canal sont obtenus grâce au contrôle électrostatique de la courbure de bandes à l' interface de diamant/oxyde. Pour ces deux structures, beaucoup de défis technologiques doivent être surmontés avant de pouvoir fabriquer un transistor. La dépendance en température de la densité surfacique de trous et de la mobilité de plusieurs couche de diamant delta dopées au bore a été étudiée expérimentalement et théoriquement sur une large gamme de température (6 K <T < 500 K). Deux types de conduction ont été détectés: métallique et non métallique. Une mobilité constante comprise entre 2 et 4 cm2/Vs a été mesurée pour toutes les couches delta métalliques quelle que soient leurs épaisseurs ou le substrat utilisé pour la croissance. Cette valeur particulière est discutée en comparaison à d'autres valeurs expérimentales reportées dans la littérature et aussi de calculs théoriques. Une conduction parallèle à travers les régions faiblement dopées qui encapsule la couche delta, a également été mise en évidence dans certains échantillons. Une très faible mobilité a été mesurée pour les couches delta non métalliques et a été attribuée à un mécanisme de conduction par saut. Des structures métal oxyde semi-conducteur utilisant de l'oxyde d'aluminium comme isolant et du diamant monocristallin (100) de type p en tant que semi-conducteur ont été fabriquées et étudiées par des mesures capacité tension C(V) et courant tension I(V). L'oxyde d'aluminium a été déposé en utilisant un dépôt par couche atomique (Atomic Layer Deposition : ALD) à basse température sur une surface oxygénée de diamant. Les mesures C(V) démontrent que les régimes d'accumulation , de déplétion et de déplétion profonde peuvent être contrôlés grâce à la tension de polarisation appliquée sur la grille. Un diagramme de bande est proposée et discutée pour expliquer le courant de fuite étonnamment élevé circulant en régime d’accumulation. Aucune amélioration significative de la mobilité n’a été observée dans les structures delta, même pour les plus fines d’entre elles (2 nm). Cependant, la démonstration du contrôle de l’état du canal de la structure MOS ouvre la voie pour la fabrication d’un MOSFET en diamant, même si un certain nombre de verrous technologiques subsistent. / As the demand in high power and high frequency electronics is still growing, standard semiconductors show their limits. Approaches based either on new archi- tectures or wide band gap materials should allow to overcome these limits. Diamond, with its outstanding properties, seems to be the ultimate semiconductor. Neverthe- less, it also suffers from limitations, especially the high ionization energy of the boron p-type dopant that results in a low carrier concentration at room temperature. In- novative solutions relying on 2D gas or/and field effect ionization has been imagined to overcome this problem. This work is focused on two of these solutions: i) boron delta-doping consisting in highly doped layer between two intrinsic layers, resulting in a conduction combining a high mobility with a large carrier concentration and ii) metal-oxide-semiconductor field effect transistor (MOSFET) where the conducting or insulating behavior of the channel is based on the electrostatic control of the band curvature at the oxide/semiconducting diamond interface. For both structures, a lot of technological challenges need to be surmounted before fabricating the related transistor. On one hand, the temperature dependence of the hole sheet density and mobility of several nano-metric scaled delta boron doped has been investigated experimentally and theoretically over a large temperature range (6 K <T< 500 K). Two types of conduction behaviors were detected : metallic and non metallic. A constant mobility between 2 and 4 cm2/V.s was found for all the metallic degenerated delta layers whatever its thickness or the substrate used for the growth. This particular value is discussed in comparison of other experimental values reported in literature and theoretical calculations. A parallel conduction through the low doped regions, in which the delta is embedded, has also been brought to light in certain cases. A very low mobility was measured for non metallic conduction delta layers and has been attributed to an hopping conduction mechanism which is discussed. On the other hand, metal-oxide-semiconductor structures with aluminum oxide as insulator and p−type (100) mono-crystalline diamond as semiconductor have been fabricated and investigated by capacitance versus voltage C(V) and current versus voltage I(V) measurements. The aluminum oxide dielectric was deposited using low temperature atomic layer deposition on an oxygenated diamond surface. The C(V) measurements demonstrate that accumulation, depletion and deep depletion regimes can be controlled by the bias voltage. A band diagram is proposed and discussed to explain the surprisingly high leakage current flowing in accumulation regimes. To sum up, no significant improvement of mobility has been observed in delta structures even for the thinnest one (2 nm). However, the MOS channel control demonstration opens the route for diamond MOSFET even if technological chal- lenges remain.
