Sur de nombreuses pièces et structures, la peinture garantit une protection de surface et assure l'esthétique du produit final. Cependant, l'arrivée de nouvelles directives visant à réduire les sources de rejets majoritaires de Composés Organiques Volatiles (COV) incite les industriels à s'orienter vers des technologies alternatives aux peintures solvantées classiques, telles que les revêtements poudres. Dans le cas d'un substrat non-conducteur thermosensible, cette substitution implique de développer de nouvelles méthodes de mise en œuvre et d'en optimiser les paramètres.Ce travail de thèse vise à maîtriser l'adhérence et à comprendre les phénomènes d'adhésion de peintures poudre sur substrats composites à matrice organique, d'un point de vue physico-chimique. Notre travail s'est articulé autour d'une peinture poudre et de deux substrats composites dont l'un possède une matrice thermodurcissable (époxy) et l'autre une matrice thermoplastique (PEEK).Dans un premier temps, nous avons analysé l'influence des conditions de mise en œuvre sur l'interface substrat époxy/revêtement, afin de déterminer quel procédé favorise le plus l'adhérence entre la méthode "fond de moule" et l'application directe. Nous nous sommes, ensuite, intéressés à la durabilité de ces systèmes revêtus lors d'un vieillissement hygrothermique. Enfin, nous avons étudié l'effet des traitements plasmas atmosphérique et basse pression sur l'adhérence entre le revêtement poudre et le substrat à matrice PEEK.

On many products and structures, the painting ensures surface protection and provides aesthetic of final product. However, the new guidelines to reduce the main release's sources of Volatile Organic Compounds (VOCs) incite the industrials to use alternative to usual solvent-based paints such as powder coatings. In the case of non-conductive and heat-sensitive substrate, this substitution involves the development of new processes and the optimization of their parameters.This thesis is about controlling adhesion and understanding the adhesion of powder coatings on organic matrix composites substrates, on a physico-chemical point of view. Our work focus on a powder coating and two substrates, one containing thermosetting resin (epoxy) and the other a thermoplastic resin (PEEK) .As a first step, we analyzed the influence of the characteristic of the process on the epoxy substrate/coating interface to determine which one promotes the best adhesion between the "in mold-coating" and direct application. Then we studied the durability of these coated systems in a hydrothermal aging. Finally, we studied the effect of atmospheric plasma treatment and low pressure plasma treatment on the adhesion between powder coating and PEEK matrix substrate.

▼ The statistical mechanical theory of hydrophobic interactions was initiated decades ago for purely repulsive hydrophobic species, in fact, originally for hard-sphere solutes in liquid water. Systems which treat only repulsive solute-water interactions obviously differ from the real world situation. The issue of the changes to be expected from inclusion of realistic attractive solute-water interactions has been of specific interest also for decades. We consider the local molecular field (LMF) theory for the effects of solute attractive forces on hydrophobic interactions. The principal result of LMF theory is outlined, then tested by obtaining radial distribution functions (rdfs) for Ar atoms in water, with and without attractive interactions distinguished by the Weeks-Chandler-Andersen (WCA) separation. Change from purely repulsive atomic solute interactions to include realistic attractive interactions substantially diminishes the strength of hydrophobic bonds. Since attractions make a big contribution to hydrophobic interactions, Pratt-Chandler theory, which did not include attractions, should not be naively compared to computer simulation results with general physical interactions, including attractions. Lack of general appreciation of this point has lead to mistaken comparisons throughout the history of this subject. The rdfs permit evaluation of osmotic second virial coefficients B2. Those B2 are consistent with the conclusion that incorporation of attractive interactions leads to more positive (repulsive) values. In all cases here, B2 becomes more attractive with increasing temperature below T = 360K, the so-call inverse temperature behavior. In 2010, the Gulf of Mexico Macondo well (Deepwater Horizon) oil spill focused the attention of the world on water-oil phase equilibrium. In response to the disaster, chemical dispersants were applied to break oil slicks into droplets and thus to avoid large-scale fouling of beaches and to speed up biodegradation. Eventually the dispersant COREXIT 9500 was used predominantly in responding to this accident. The formulation of COREXIT dispersants is somewhat complicated and the various constituents (and their interactions) deserve exhaustive study. Here we focus on sorbitan monooleate (SPAN80), one important component of COREXIT 9500, and we investigate its behavior in oil-water-surfactant systems. Extensive all-atom molecular dynamics calculations on the water-squalane interface for nine different loadings with SPAN80, at T=300K, are analyzed for the surface tension equation of state, desorption free energy profiles as they depend on loading, and to evaluate escape times for absorbed SPAN80 into the bulk phases. These results suggest that loading only weakly affects accommodation of a SPAN80 molecule by this squalane-water interface. Specifically, the surface tension equation of state is simple from conditions of low loading (high tension) to high loading (lower tension) studied, and the desorption free energy profiles are weakly dependent on loading here.

▼ This dissertation aims to study finite element methods for two-dimensional stationary second order interface model problems on homogeneous and heterogeneous media, under discretizations non-fitted with the interface. We propose novel numerical methods for the model interface problems, proving optimal convergence of the errors and robust error estimates with respect to the curvature of the interface and the physical parameters of the problems. In the first part of the dissertation, we consider the Poisson and Stokes interface problems on homogeneous media. In both cases, we design correction terms relying on the interface jump conditions of the problem for each unknown variable, which are then added to the right-hand side of the system. This technique is developed for arbitrary polynomial order of the finite element subspace, by means of higher order derivative jumps of the solution derived from the problem. We provide pointwise error analyses of the methods obtaining optimal convergence of the errors. The second part assesses the classical elliptic interface model problem on heterogeneous media: Poisson equations with discontinuous constant coefficients. In particular, we examine the case in which the contrast of the diffusion coefficients is high. We present an a priori analysis of the regularity in order to develop error estimates for the numerical methods consistent with the behavior of the solution. Furthermore, we propose and analyze two finite element methods, following distinct approaches, for the high contrast Poisson interface problem. The first method follows the philosophy of Immersed Finite Element methods, incorporating the jump conditions of the problem strongly in the finite element subspace. Optimal error estimates independent of the contrast of the diffusion coefficients are proved. A detailed analysis incorporating the curvature of the interface and the regularity of the solution is presented, guaranteeing robustness of the method. The second numerical approximation is based on a Nitsche finite element method, with flux stabilization terms. This approach imposes the jumps conditions of the problem weakly, in the form of penalty terms with support on the interface that are added to the system. Optimal error estimates independent of the high-contrast are demonstrated, including a novel error estimate for the flux of the solution. Finally, numerical evidence of the properties of the finite element approximations are displayed for each problem, corroborating the theoretical findings.

Qual a visão, por parte dos fabricantes e construtores, quanto aos problemas de integração dos elevadores? Como o usuário age frente ao produto e suas limitações? Elevadores são conjuntos mecânicos complexos, compostos por um número muito grande de peças, que em geral possuem dimensões genéricas. Tal afirmação não é propriamente uma novidade, nem mesmo as dificuldades características que envolvem o processo produtivo deste veículo de transporte vertical. Porém, quando analisamos o elevador sob outra perspectiva, nos deparamos com dois problemas básicos e relativamente específicos: A integração com a arquitetura e a interface com o usuário. A questão de pesquisa refere-se a como as empresas do setor de elevadores e construção civil tratam a integração de produtos de conceitos diferentes, tanto na criação quanto na produção, e paralelamente, como se comporta o usuário deste tipo de transporte, frente ao mercado e também na relação direta com o produto. A partir destas questões, surge a necessidade de identificar as práticas e posturas de fabricantes, usuários, construtores e arquitetos para a questão da integração. Não menos importante é a necessidade de verificar a postura ética e social das empresas pesquisadas, no quesito projetual e na interface com o usuário. Como base teórica, foi realizado um estudo do elevador, mostrando de maneira básica a sua trajetória de desenvolvimento, até o estado da arte em nível mundial. O método escolhido foi o estudo descritivo, com a utilização de questionários direcionados a atingir os objetivos propostos, aplicados em três empresas fabricantes de elevadores, cinco empresas da construção civil, dois escritórios de arquitetura e design e 82 usuários. Como consideração inicial deste estudo, verificou-se que as empresas e escritórios pesquisados possuem dificuldades em gerar produtos conceitualmente diferentes para posterior integração, em geral não atuam de forma pró-ativa, pois esperam concretização de tendências de mercado para agirem. Há um grande potencial de redução de problemas de inter-relação que se encontra barrado por feudos técnicos ou pura interpretação incorreta de segmentação, ou ainda pouco conhecimento da atitude do usuário. E o usuário por sua vez, conhece pouco e atua menos ainda para a melhoria do produto.

What is the vision from manufacturers and builders side, as for the elevators integration issues? How is the users behavior facing the product and its limitations? Elevators are complex mechanics assemblies, composed by a huge number of parts, which in general are designed in generic dimensions. Such statement is not properly an innovation, not even the characteristic difficulties that involve the productive process of this vehicle of vertical transportation. However, when we analyzed the elevator under other perspective, we came across two basic problems and relatively specific: The integration with the architecture and the interface with the user. The research issue refers to the way that the elevator companies and builders site treat the product interface…

Este estudo avaliou a influência da ciclagem térmica e mecânica, aliadas, na resistência ao cisalhamento da interface entre porcelana de cobertura e infraestruturas de diferentes sistemas totalmente. Também foi realizada a caracterização das interfaces por meio de análise de espectroscopia por energia dispersiva de Raios X (EDS). Foram testados sistemas totalmente cerâmicos a base de dissilicato de lítio (DL), zircônia tetragonal estabilizada por ítrio recoberta por estratificação (ZC) e por injeção (ZI) e alumina infiltrada por vidro (AI). Um grupo metalocerâmico a base de liga de CoCr foi testado como grupo controle. Vinte espécimes circulares de 6mm de diâmetro de cada sistema foram submetidos ao teste de resistência ao cisalhamento em máquina de ensaios mecânicos, sendo que metade destes (n=10) sofreram os procedimentos de ciclagem térmica e mecânica antes da realização dos testes. Os resultados foram analisados através do teste ANOVA a dois critérios (p<0,05) e utilizou-se teste de Tukey (p<0,05) para as comparações múltiplas. Análise das fratura foi realizada através de estereomicroscópio e MEV. A análise de EDS foi realizada ao longo da interface infraestrutura/porcelana de cobertura em um espécime de cada sistema seccionado longitudinalmente. As ciclagens térmica e mecânica aliadas não influenciaram na resistência ao cisalhamento dos sistemas testados. Houve, contudo, diferença estatística entre os sistemas testados. O grupo CoCr apresentou os maiores valores (34,72 ± 7,05 Mpa), seguido dos grupos DL (27,07 ± 5,28), ZI (23,58 ± 2,71), ZC (22,46 ± 2,08) e AI (18,15 ± 1,99). Os modos de fratura foram predominantemente adesivos para o grupo CoCr, coesivos na infraestrura para o grupo DL, coesivo na porcelana de cobertura para os grupos ZC e ZI, e mistos para o grupo AI. As análises de EDS mostraram haver uma zona de interação para todos os sistemas testados. Deste modo, é possível sugerir, através das análises de fratura e de EDS, que haja uma união química entre a porcelana de cobertura e infraestrutura nos diferentes sistemas testados e que as variações de resistência ao cisalhamento estão relacionadas a fatores intrínsecos ou na capacidade de molhamento da porcelana de cobertura.

The objective of this study was to evaluate the influence of thermal and mechanical cycling on the shear bond strength of different all-ceramic cores and veneering porcelain interfaces. It was also to characterize chemically the interfaces by energy dispersive spectroscopy (EDS). The allceramic systems tested were lithium dissilicate (DL), zirconia veneered by layering technic (ZC) or pressing technic (ZI) and glass infiltrated alumina (AI). A CoCr group was used as control. Twenty cylindrical specimens for each system were subjected to shear bond strength in a universal testing machine with a 0.5 mm/min crosshead speed. Half of the specimens (n=10) were thermal and mechanical cycled before shear bond strength was carried out. Mean shear bond strength (MPa) were analyzed with a 2-way analysis of variance…

O projeto tem como proposito estudar o comportamento elétrico da microestrutura e interface de tungstato de prata e do tungstato de prata com nanoparticulas de prata focando em uma possível aplicação como dispositivo eletrônico. Os rods de α-Ag2WO4 foram sintetizadas utilizando o método hidrotermal assistido por microondas e posteriormente submetidas a um feixe de elétrons fazendo com que os íons de prata Ag+, dentro do bulk do cristal, sejam reduzidos e migrem para a superfície do material crescendo as partículas metálicas. A nucleação desses filamentos podem ser visualizado ao vivo e in situ acompanhando as imagens de MEV-FEG da matrix do material. A fase do material, posições atômicas e o entendimento da distrorção da rede foi confirmada pela difratometria de raio-X com o refinamento Rietveld. O material foi caracterizado, estruturalmente, pelas técnicas de espectroscopia Raman e infravermelho, na qual consegue entender quais são as ligações a curto alcance que os átomos estão fazendo. Foi estudado o seu comportamento eletrônico e espectroscópico, por medidas de espectroscopia de UV-Vis-NIR determinando o valor de bandgap do material. Por meio das medidas de XPS foi possível comparar o a pureza e o o grau de oxidação da superfície. E finalmente, foram realizadas medidas de espectroscopia de impedância e condutividade elétrica em regime DC do material não-irradiado e irradiado para com o feixe de elétrons para se entender o mecanismo de condução elétrica. Pelas curvas de impedância, é possível perceber que as amostras irradiadas possuem uma resistência maior causada pelos defeitos gerados dentro da estrutura dificultando a mobilidade dentro do cristal. Foi possível notar pelas medidas elétricas, que a formação dessa superfície com o nanoparticulas altera o o contato entre os cristais do material, apresenta um desvio da linearidade, essa a fase no contorno estaria permitindo a migração dos portadores de carga nos limites dos cristais de tungstato.

This project have to aim study the electrical conduction behavior of silver tungsten and silver tungsten with Ag nanoparticles microstructures and interface on focus in a possible application in electronic device. The rods of α-Ag2WO4 were synthetized using a microwave assisted method and then target by a electron beam, making the Ag+ ions inside of the crystal, reduce and go out to surface material as nanoparticles of Ag0 metallic. This growth can be view in situ by MEV-FEG. The phase of material, atomic position and structure distortion was confirmed by DRX pattern with Rietveld refinement. The material was structural characterized for Raman and infrared spectroscopy, which could be understood what bonds at short range the atoms was doing. The electronic behavior was study by UV-Vis-NIR spectroscopy for determine the bandgap. XPS measurements were performed to compare the purity of the surface and the degree of oxidation. Finally, the samples non-irradiated and irradiated were characterized electrical with impedance spectroscopy and electrical conductivity…

The introduction of computerized systems in the workplace provides a range of facilities and amenities for its users, but also is responsible for new and different kinds of difficulties. In this research seeks to verify the software CADI-JUS support the needs of the activities of registration / consultation of information relating to building and land of the Justiça Federal. Based on methodological assumptions of ergonomics, the method of study follows the principles that underlie the formulation of Ergonomic Analysis of Work - AET enriched with procedures formulated by Silvino (2004) called the Tecnologia de Avaliação e (Re)Concepção de Interfaces - TAI. The study is divided into two stages. The first, Planning, represents the completion of (a) document analysis, (b) semi-structured interviews, and (c) meetings with authorities of the institution and the control of the application. The second, analysis of the application, staff on the achievement of (d) an intrinsic analysis, and (e) extrinsic analysis of application. Therefore, we assessed by means of these approaches the factors that influence the use of the software, so that the end of the research is produced a report and diagnosis of these factors, coupled with these recommendations that support the needs of application usage in a situation work. The results reaffirm that the way the new IT systems are developed favors the emergence of tools focused on technology and that in most cases ignore the basic criteria of usability.

A inserção de sistemas informatizados no ambiente de trabalho proporciona uma série de facilidades e comodidades para os seus usuários, como também é responsável por novos e diferentes tipos de dificuldades. Nessa pesquisa busca-se verificar se o software CADI-JUS atende as necessidades das atividades de cadastramento/consulta de informações referentes aos imóveis e terrenos da Justiça Federal. Com base em pressupostos metodológicos da Ergonomia, o método do estudo acompanha os princípios que subsidiam a formulação da Análise Ergonômica do Trabalho - AET enriquecida por procedimentos formulados por Silvino (2004) denominado de Tecnologia de Avaliação e (Re)Concepção de Interfaces TAI. O estudo divide-se em duas etapas.

La prise de conscience mondiale des enjeux environnementaux a conduit à l’émergence de composites«verts», dans lesquels les fibres naturelles sont amenées à remplacer les fibres synthétiques. Ces nouveaux matériaux offrent des alternatives écologiques aux composites synthétiques traditionnels mais sont difficilement utilisables pour des applications semi-structurales ou structurales. Une solution possible à ce problème est le développement des composites hybrides, en combinant ensemble fibres naturelles et synthétiques. Dans ce cadre, l'objectif de cette étude était de développer des composites hybrides à base de fibres de basalte et de lin. Les composites hybrides ont été élaborés par moulage par infusion sous vide avec une matrice époxy. À des fins de comparaison,des composites 100% à fibres de lin et100%à fibres de basalte ont également été produits. Une caractérisation mécanique quasi-statique et dynamique amontré que l'hybridation permet d’obtenir un composite avec des propriétés mécaniques intermédiaires comparées à celles des composites à fibres de lin ou de basalte. Cependant, l’analyse approfondie des dommages a montré la nécessité d'optimiser la qualité d'adhésion de l'interface fibre/matrice afin d'accroître les performances mécaniques des composites hybrides obtenus. Pour cette raison, différents traitements de modification de surface ont été développés et étudiés pour les fibres de lin et de basalte. Un traitement physique par plasma (Plasma Enhanced Chemical Vapor Deposition) a été appliqué aux fibres de lin et de basalte. Les fibres de lin ont également été soumises à deux traitements chimiques utilisant des espèces enzymatiques et du CO2supercritique. Les effets des traitements sur la stabilité thermique, la morphologie et les propriétés mécaniques des fibres de lin et de basalte ont été étudiés. L’adhérence fibre/matrice a été analysée en réalisant des tests de fragmentation sur des composites monofilamentaires. La qualité de l'adhésion entre les fibres et les matrices époxy et vinylester a été évaluée en termes de longueur critique de fragment, de longueur de décohésion interfaciale et de résistance au cisaillement interfacial. La micto-tomographie haute résolution a été utilisée pour analyser les mécanismes d'endommagement lors des tests de fragmentation. Pour les deux types de fibres, les meilleurs résultat sont été obtenus grâce au traitement par plasma. Ce traitement a consisté à déposer un revêtement homogène de tétravinylsilane à la surface des fibres de basalte et de lin, ce qui a permis une augmentation significative de l’adhérence fibre/matrice, ouvrant ainsi la voie à la prochaine génération de composites hybrides plus respectueux de l’environnement et utilisables pour des applications semi-structurales.

Global awareness of environmental issues has resulted in the emergence of “green” composites, in which natural fibres are used to replace synthetic ones. However, in semi-or structural applications, it can be inconvenient to use composites based on natural fibres. A possible solution to…

Les interfaces cerveau-machine (ICM) utilisent les signaux émis par le cerveau pour contrôler des machines ainsi que des appareils (claviers, voitures, neuro-prothèses). Après plusieurs décennies de développement, les techniques de ICM modernes montrent une maturité relative par rapport aux dernières décennies et reçoivent de plus en plus d'attention dans les applications grand public du monde réel, en particulier dans le domaine des interactions homme-machine pour personnes en bonne santé, par exemple les neuro-jeux. L'objectif de cette thèse est de développer un modèle d'ICM et des algorithmes de traitement de signaux EEG pour relever ces défis, donc conduire à une ICM non-invasive, portable et facile à utiliser, exploitant des rythmes EEG pour les applications grand public (non médicales). Pour atteindre cet objectif, un examen de l'état de l'art (prototypes existants et produits commerciaux, configurations expérimentales, algorithmes) a d'abord été effectué pour acquérir une bonne compréhension de ce domaine. Les contributions de cette thèse comprennent : 1) un paradigme ICM hybride avec peu d'électrodes, 2) la réduction de la dimensionnalité pour l'ICM multi-canal (avec un nombre élevé d'électrodes), 3) la réduction et la sélection de canal, 4) l'amélioration de la classification pour l'ICM avec des électrodes prédéterminées. Les résultats expérimentaux montrent que les méthodes proposées dans cette thèse peuvent améliorer les performances de classification et/ou augmenter l'efficacité du système (par exemple, réduire le temps d'apprentissage, réduire le coût du matériel), de manière à contribuer à des ICM pour des applications générales.

Brain-computer interfaces (BCIs) use signals from the brain to control machines and devices (keyboards , cars, neuro- prostheses) . After several decades of development, modern BCI techniques show a relative maturity compared to the past decades and receive more and more attention in real-world general public applications, in particular in the domain of BCI-based human-computer interactions for healthy people, such as neuro-games. The aim of this thesis is to develop an experimental setup and signal processing algorithms for non-invasive, portable and easy-to-use BCI systems for large public (non-medical) applications. To achieve this goal, a review of the state of the art (existing prototypes and commercial products, experimental setup, algorithms) is first performed to get a full scope and a good understanding in this field. The main contributions of this thesis include: 1) a hybrid BCI paradigm with a few electrodes , 2) dimensionality reduction for multi-channel BCI (with a high number of electrodes ), 3) reduction and selection channel , 4) improved classification for BCI with a few predetermined electrodes. The experimental results show that the methods proposed in this thesis can improve classification performance and / or increase the efficiency of the system ( for example, reduce the learning time, reduce the cost of equipment ) , so as to contribute to BCI for the…

▼ Solar photovoltaics (PV) offer a sustainable solution to the daunting challenge of meeting the global energy demand. Perovskite solar cells, whose high efficiencies are attainable via low-cost and high-throughput solution processing, are an emerging technology that has captivated the PV research community. Further advances in efficiency are limited by the abundant interfaces that make up these polycrystalline devices. Important issues in perovskite device operation, such as instability and hysteresis, arise from perovskitesâ ionic nature, and need to be addressed for this technology to fulfill its potential. In this thesis, I explore interfaces within perovskite devices: grain boundaries, and electron- and hole-extraction junctions. With the aid of density functional theory (DFT) simulations and nano-probe characterization, I provide insight into the origins of defect formation and hysteresis. By leveraging these findings, I demonstrate control of film growth conditions and interface materials chemistry to create new device architectures with improved performance. The DFT-based analysis of defect formation energies identifies the key defects (Pb atom substituted by I, known as antisites) and indicates that films grown under iodine-rich conditions are prone to forming deep electronic traps. This finding motivated my exploration of a new precursor (anhydrate lead acetate) for device-quality films. I then report the first perovskite-PCBM hybrid solid. Here, I find that PCBM, when it infiltrates throughout the grain boundaries and electron-extraction interfaces, suppresses hysteresis in devices. Materials characterization and DFT simulations reveal the PCBM-perovskite interaction: the PCBM passivates the key defects during the perovskite self-assembly. Using conductive AFM, I reveal the memristive properties of perovskite films and identify the major origin of hysteresis as ion, especially halide, migration. I close by developing the first crosslinked hole-extraction top contact with the goal of obviating degradation of the underlying perovskite. A remote-doping strategy introduces the needed hole conductivity. The new top contact produces an insoluble and heat-resistant protecting interlayer that is band-aligned with the perovskite. The resultant family of devices is hysteresis-free, with fill factors exceeding 80% and resilience to thermal stresses that exceed 100Ë C, conditions under which conventionally-contacted devices fail. This top contact methodology also paves the way for building multi-junction devices on top of the perovskite cell. I close this work by offering a roadmap for future improvements in perovskite photovoltaics. Advisors/Committee Members: Sargent, Edward H, Electrical and Computer Engineering.

For molecular events that occur at biological interfaces, MD is unique in being able to simultaneously probe small spatial and temporal scales. This unparalleled resolution offers unique insight to the specific interactions that govern interfacial processes. In the context of this dissertation, MD is applied to processes in membrane biology and biofuel research. Through the use of the Highly Mobile Membrane Mimetic (HMMM) to accelerate phospholipid motion, we show that phospholipid tails insert significantly faster than they do in a conventional bilayer, and repeated insertion of the peripheral membrane protein α-synuclein shows larger conformational variability in the HMMM than was observed in conventional bilayers. Separately, simulations of C2 domain binding of synaptogamin (Syt) to the HMMM demonstrate clear differences in the binding properties between Syt isoforms, and explain the atomic origins of the observed differential kinetics between Syt-1 and Syt-7. Development of the HMMM to extend its applicability to transmembrane systems is also discussed. Transmembrane systems in conventional bilayers are also presented. In conjunction with the parameterization of ubiquinone, its binding and dynamics are reported in both the QA and QB sites of the photosynthetic reaction center of Rhodobacter sphaeroides and the quinone-binding site of ubiquinol oxidase. Recent structural work on the polyaromatic cation transporter EmrE, and its electrostatic locking mechanism governing conformational change, are also discussed. Interactions at the interface of cellulose have also been simulated. The impact of lytic polysaccharide monooxygenase (LPMO) action on cellulose structure and potential product inhibition of cellulose degrading enzymes by oxidized cellulose were monitored while on practicum at the National Renewable Energy Laboratory. Similarly, the mechanism of how lignin interferes with cellulose degradation by cellulases was determined by a multimillion atom simulation analyzed while on practicum at Oak Ridge National Laboratory.

Au cours des dix dernières années, les hétérostructures à base de matériaux oxyde ont été grandement étudiées comme potentiel systèmes d’application pour le nanoélectronique. Parmi eux, les ferroélectriques (FE) sont particulièrement intéressants comme support pour ces applications technologies. En effet, leur polarisation électrique spontanée, aisément réversible par application d’un champ électrique en fait de bons candidats pour le stockage de données non-volatile. Renverser la polarisation nécessite un contact avec une électrode, ainsi les hétérostructures de films mince de FE avec électrodes métalliques ont été grandement étudiées. A l’interface entre les deux matériaux, les charges libres de l’électrode permettent d’écranter les charges de surfaces, détrimentales au maintien de la polarisation au sein du film FE. Avec des électrodes d’oxyde métalliques, un déplacement ionique à l’interface électrode/FE va d’avantage favoriser cet écrantage, plaçant l’interface au cœur du processus d’écrantage. Cependant, malgré d’importantes découvertes théoriques, les données expérimentales sont rares et le comportement exact de l’interface électrode/FE est seulement partiellement maitrisée. Une plus grande compréhension est indispensable pour une intégration correcte des films FE dans des dispositifs nanométriques. Dans cette thèse, des techniques basées sur la spectroscopie de photoémission sont utilisées pour sonder l’interface enfouie d’une hétérostructure électrode/BaTiO₃/électrode, dans le cas de deux électrodes différentes : l’oxyde métallique SrRuO₃ et le métal cobalt. Nous avons acquis des informations sur le comportement de l’interface et sa réponse au renversement de la polarisation. Ce travail est un nouveau pas vers une plus grande maitrise des phénomènes physiques gouvernant le comportement de l’interface entre électrodes le ferroélectrique BaTiO₃, en termes de propriété électronique, de cinétique et de fatigue. Les expériences présentées couplent des techniques d’analyses de pointes, où l’utilisation de rayons X durs et l’application de champs électriques in situ ont rendus possible la difficile tâche de sonder des interfaces enfouies en condition de fonctionnement.

In the past decade, oxide-based heterostructures have been studied extensively as potentially attractive systems for applications in nanoelectronics. Among them, ferroelectric materials raised interest as potential support for those technological applications. Indeed, their spontaneous electric polarization easily switched by applying an electric field makes them a good basis for non-volatile data storage. Switching the polarization requires a metallic contact with an electrode, thus heterostructures of ferroelectric thin films with metallic electrodes have been widely studied. At the interface between those two materials, free charges of the electrode help screening the polarization induced surface charges detrimental to maintaining proper polarization in the ferroelectric thin film. With metallic oxide electrodes, an ionic displacement at the…

▼ Atualmente, o uso de sistemas de informação está amplamente difundido, sendo que praticamente todas as áreas de negócio têm necessidade de tais sistemas. Estes sistemas são formados por funcionalidades que implementam regras do negócio e persistem os dados em bases de dados. Os usuários podem utilizar estes sistemas através das interfaces de usuário, que são as unidades onde estão implementadas as funcionalidades, que estão estruturadas por meio de menus. Através destes menus, o usuário pode navegar e selecionar aquela interface de usuário que contenha a funcionalidade que ele está buscando. A motivação para este trabalho veio da grande dificuldade que é manter sistemas, em uma linha de produção de software, íntegros do ponto de vista das interfaces do usuário. A cada sistema novo ou manutenção em sistema já existente, garantir que as interfaces do usuário tenham os mesmos padrões de aparência e comportamento, exige um grande esforço de verificação e validação, o que pode ser minimizado por um processo onde a estrutura das interfaces do usuário esteja em um modelo baseado em padrões. Sempre que uma aparência ou comportamento for alterado para um padrão, ele pode ser replicado em todos os sistemas modelados, permitindo, assim, não somente uma melhoria na produtividade como também um ganho em qualidade. O objetivo principal deste trabalho é definir e validar um metamodelo que permita modelar a estrutura destas interfaces de usuário de um sistema de informação. Para construir este metamodelo, foi escolhida uma estrutura de grafos. Esta escolha foi devido à naturalidade com que uma interface de usuário pode ser representada como um vértice e os relacionamentos por arestas. Inicialmente foram identificados e normalizados os padrões das interfaces de usuário de uma grande amostra de sistemas de informação. O metamodelo foi construído com base nestes padrões. Utilizando este metamodelo, foi possível construir modelos completos para um sistema hipotético e para três sistemas reais, comprovando que ele pode ser usado na modelagem das interfaces de usuário de outros sistemas similares.

▼ This thesis highlighted a micro-hermetic packaging platform based on ultra-thin fused silica capsules, for development of modularized and distributed Neural Interface Systems. Test vehicles (TV1 and TV2) were designed and tested as proof-of-concepts, in collaboration with General Electric (GE) Global Research Center. TV1 devices are low-profile fused silica capsules (8 mm by 4 mm by 0.3 mm) with four side-feedthroughs for signal breakout. We developed a custom Encapsulation Test System (ETS) to apply saline soak test to multiple test vehicles at elevated temperature and to perform pA-level fine current measurements. 2 TV1 devices (batch-1) were tested for a total number of 400 days (at 57 °C and 87 °C) and 4 TV2 devices (batch-2) at 87 °C for 100 days. Both in-plane and out-of-plane leakage currents are below 200 nA on all 6 devices. Visual inspection under the microscope revealed no moisture nor ion ingress into the capsules. Compare groups (8 Kapton-based devices and 4 PCB-based devices) with similar electrical patterns were encapsulated with Polydimethylsiloxane (PDMS) and were evaluated under the same test conditions. Metal corrosion, electromigration, ion ingress, and significant leakage currents (>1 μA) were observed on the compare groups. TV2 devices are wireless and battery-less circuits sealed in feedthrough-free capsules (21mm by 21mm by 2.1mm). We built a Wireless Encapsulation Test System (WETS) that delivers RF power to multiple TV2 devices and harvests photonic (infrared) data patterns from the TV2 devices. 2 TV2 devices (batch-1) were tested for over 4 months in the ambient environment and in the saline bath. Both devices are functional, with consistent moisture buildup within the capsules caused by outgassing from the polymeric materials (relative humidity level increased by 10% and 5% on two devices respectively). 4 TV2 devices (batch-2) with pre-drying procedures have been tested for 50 days. Relative humidity level has increased to 1% only on 1 out of 4 devices. As the hermeticity of the fused silica capsules are demonstrated, hermetic, high-density feedthroughs will be fabricated in the future on the capsules to enable integration of Microelectrode array (MEA) for neural applications.

▼ A primary goal of intracortical Brain-Computer Interface (iBCI) technology is to restore communication and independence for people with motor disabilities. The BrainGate System is an investigational iBCI designed to provide severely paralyzed individuals control over assistive communication devices by recording and decoding their intracortical neural signals. An iBCI system can be used as a communication platform if the decoding algorithms are able to translate the neural signals into a continuous directional control of a computer cursor and, in parallel, to decode a discrete click state for the selection of an icon or a key on a virtual keyboard. Past iBCI research has focused on the optimization of directional control. In contrast, this thesis focuses on improving classification methods of the participant's intended click state to increase communication rate and accuracy. Here the optimization of online state decoding methods was addressed through four major points: selection of training data, selection of neural features, classification schemes, and robust parameter estimation. The click state decoding problem is challenging due to few intrinsic characteristics of the neural signals such as non-stationary and visual context dependencies. These two phenomena can cause deviations from the expected statistical properties of the recorded signals leading to possible misclassifications of an intended click. For instance, throughout the decoder calibration process, the participant’s neural signals change as the participant is provided with more feedback of the decoded cursor direction. Limitations of the established state decoding approach were first addressed by an improved feature space and parameter estimation where the state decoder is trained with only the neural data that best reflects closed-loop point and click control. Next, a non-parametric feature selection method (the Wilcoxon rank-sum test) was investigated to remove assumptions on the underlying class distributions. This non-parametric approach selected neural features that improved downstream dimensionality reduction and were subsequently used successfully for closed-loop click control. On the decoding part of the problem, two variants of the Linear Discriminant Analysis (LDA) method, that complement the complex neural data, were implemented. First, a Multiple Class LDA (MCLDA), which breaks down the continuous cursor movement signal into eight directional classes was investigated. Second, the Local Fisher Discriminant Analysis (LFDA) method, that preserves the local structure of the high dimensional neural data, was implemented. The LFDA method was enhanced by fitting each class distribution in the feature space with a Gaussian Mixture Model (GMM) optimized with Variational Bayesian inference (VB) . With a full Bayesian model, VB converges on densely organized data and automatically determines an appropriate mixture number. Once all the algorithms were implemented in the BrainGate system, an online comparison was performed to investigate the differences… Advisors/Committee Members: Simeral, John (Advisor), Borton, David (Advisor), Truccolo, Wilson (Reader), Hochberg, Leigh (Reader).

La microchirurgie de l’oreille moyenne requiert une forte dextérité en raison de la finesse et de l’extrême sensibilité des structures impliquées. L’apprentissage de cette chirurgie est délicat et est effectué en fin d’internat. Ce travail porte sur le développement d’un modèle mécanique en éléments finis des différentes structures qui composent l’oreille moyenne dans le but de concevoir un simulateur chirurgical. Les objectifs sont de fournir un outil polyvalent pour l’apprentissage et l’entraînement de la chirurgie par la chirurgie, ainsi que d’offrir la possibilité d’explorer et d’évaluer de nouvelles procédures chirurgicales liées à l’apport de nouvelles technologies telles que la robotique. Le comportement mécanique du modèle développé a été confronté avec succès aux observations réalisées sur des pièces anatomiques. Afin d’obtenir un outil de simulation qui tienne compte des différences anatomiques de chaque patient, une méthode de déformation de l’atlas mécanique basée sur l’imagerie clinique a été implémentée. Les simulations du fraisage de la platine de l’étrier ainsi que le placement d’une prothèse ossiculaire ont été réalisées à l’aide d’une interface haptique et d’une nouvelle approche du rendu. Ce travail constitue ainsi le premier simulateur virtuel de chirurgie de l’oreille moyenne. Enfin le robot télé-opéré, RobOtol, a été intégré au simulateur afin d’étudier de nouvelles procédures chirurgicales robotisées. Le travail effectué porte essentiellement sur la simulation interactive réaliste de procédures chirurgicales complexes ainsi que la formation et la robotisation de la microchirurgie otologique.

Microsurgery of the middle ear requires high dexterity due to the finesse and the extreme sensitivity of the structures involved. Learning this surgery is delicate and is performed at the end of the residency. This work focuses on the development of a mechanical finite element model of the anatomical structures that compose the middle ear in order to design a surgical simulator. The objectives are to provide a versatile tool for learning and training of the surgery by surgical practice, as well as the opportunity to explore and evaluate new surgical procedures related to new technologies such as robotics. The mechanical behavior of the developed model was successfully confronted with observations on human specimens. In order to obtain a simulation tool that takes into account the anatomical differences of each patient, a deformation approach of our mechanical atlas, based on clinical imaging, was implemented. Simulations of the stapes footplate drilling and the placement of an ossicular prosthesis were performed using a haptic interface and a novel rendering approach. This work is thus the first virtual simulator of the middle ear surgery. Finally the tele-operated robot, called RobOtol was incorporate in the simulator to explore new robot-based surgical procedures. In addition, the simulation allows to train the otologists to the use of the robot. This work concerns mainly on the interactive simulation…

Le besoin fondamental de cette étude est de pouvoir prévoir fidèlement le comportement de la structure finale de fil, basée sur le comportement physique et les propriétés mécaniques sous différentes charges appliquées de l'éventail de structures disponibles. Au delà du caractère scientifique de la prévision, on peut utiliser le même fondement informatisé pour simuler virtuellement les tests et expériences de laboratoire (prédiction de nouveau matériau technique) ou pour générer des animations réalistes à caractères artistiques (design de textile habillement). Par conséquent, modéliser et prédire les différents comportements dans la chaîne de création textile par l’outil informatique fournit un gain de temps et de main d'œuvre considérables. La simulation des essais de laboratoire de produits textiles dans le secteur habillement peut par la suite mener à des produits améliorés, conduire à des taux plus élevés de succès de produit ou réduire la quantité de produits invendus, et entraîner au final une hausse du chiffre d'affaire. Par l'infographie, il est possible de mettre en œuvre une chaîne virtuelle de tests comparatifs de produits utilisant une norme spécifique basée sur des critères de qualité de la simulation obtenue. Le côté novateur de notre travail de recherche est la structure variable-même du diamètre des fibres. Voilà comment, le modèle réel du fil est simulé, par la présentation préliminaire d’une structure 2D qui simule la variation des diamètres du fil et après par la présentation 3D de celle-ci, et le moyen dont la variation est construite, par la répétition de la portion simulée. L’utilisation des courbes d’interpolation représentées par les polynômes Bézier dans le cadre de ce travail, correspond à une nouvelle approche, surtout dans le domaine de la variation par section des fils type laine peignée.Dans ce contexte on a obtenu ainsi un modèle valable du fil, modèle qui est souhaitable à être étendu et validé aussi pour d’autres types de fils. L’objectif principal de ce travail est de compléter les recherches réalisées dans le cadre des applications de modélisation et simulation textile. Par l’utilisation des outils 3D, les entreprises peuvent réduire le temps nécessaire à l’amélioration des produits. Les conséquences immédiates sont la réduction des coûts et des heures de travail. L’augmentation de la puissance et de la vitesse des technologies de calcul, mais aussi la réduction de leur prix, font possible la mise en œuvre des outils virtuels pour améliorer le niveau réaliste et technique de la qualité des simulations.

The basic need of this study, would be to predict accurately yarn structure behavior based on the physical behavior and mechanical properties under different loads applied to the range. Beyond the scientific nature of the forecast, we can use the same computer to simulate virtually ground tests and laboratory experiments (prediction of new material technology) or to generate realistic animation art characters (design of textiles and clothing).Therefore, to model and to predict the…

Finite element analyses became predominant in engineering offices to simulate the behaviour of parts to design. Yet the bottleneck of the method remains the mesh generation. This can be explained by the fact that the CAD representation of the geometry is not suited for a finite element simulation. It can include overlapping surfaces and small features unessential for the simulation. In this thesis, we present two new methods that attempt to limit human intervention in the meshing process. Both methods rely on an implicit representation of the geometry described by a levelset function, obtained as the signed distance function to the STL triangulation of the boundary of the geometry. An unstructured mesh surrounding the geometry is then generated wherein the boundaries are embedded. The first method is based on the cutting of the elements crossed by the embedded interface. Yet imposing Dirichlet boundary conditions with Lagrange multipliers on embedded interfaces creates an over-constrained problem that produces instabilities. To remove those instabilities, a Laplace stabilization term is introduced in the formulation. But this term includes a scalar stabilization coefficient that needs to be calibrated. The second method is based on local mesh adaptation in the vicinity of the embedded interface to obtain a nearly body-fitted mesh. Anisotropic mesh adaptation is required to obtain the geometrical convergence. The mesh size in the direction normal to the interface is imposed to obtain an optimal rate of convergence. The advantage of this method is that it is not intrusive. Finally, both methods are challenged on complex geometries in linear elasticity. Convergence and time of meshing and computation are analysed. Sensitive parameters are needed to perform the computation. This limits the robustness of both methods. Yet we believe that these contributions are a building block for the path towards the full automation of mesh generation.

▼ Interfaces are ubiquitous in natural phenomena. While the description of interfaces in fluid systems is well developed, solid-fluid and solid-solid interfaces are not well understood. This deficiency is especially true for solid-solid interfaces, which play critical roles in materials engineering, solid-state physics and solid-state chemistry. In this thesis, the Gibbs theory of interfaces is generalized to describe phase boundaries under non-hydrostatic stress in multicomponent systems. We obtain equations that describe coherent solid-solid interfaces with shear stresses parallel to the boundary plane, incoherent solid-solid interfaces for certain constraint variations, solid-fluid interfaces, grain boundaries and surfaces. In the second part of the thesis, the developed theory is applied to study particular types of interfaces using atomistic simulations. We modeled solid surface, solid-liquid interface and grain boundaries. The simulations allowed to calculate values of key thermodynamic properties, clarify behavior of these properties with temperature, composition and stress and test the predictions of the theory. Surface surface free energy and surface stress in a single component system were computed as functions of temperature. The values of these two excess properties do not converge near the melting point despite the extensive surface premelting. Solid-liquid interface free energy was computed using the developed thermodynamic integration technique as a function of composition in CuAg binary alloy and as a function of biaxial strain in a single component Cu system. In the later case the equilibrium states between the non-hydrostatically stressed solid and liquid were accurately predicted using the derived Clausius–Clapeyron type equation. We show that for non-hydrostatic equilibrium interfaces stress is not unique and compute different interface stresses using our simulation data. We also studied effects of elastic deformation, temperature and chemical composition on properties of a symmetrical tilt grain boundary in Cu and CuAg alloy. Excess grain boundary free energy was computed as a function of lateral strain, normal stress and shear stress parallel to the boundary plane. We also employed the derived thermodynamic integration method to compute grain boundary free energy as a function of temperature and composition. Maxwell type relations predicted by the adsorption equation were tested and verified. We proposed a thermodynamic model of liquid nucleation on superheated grain boundaries based on the sharp-interface approximation with a disjoining potential. The model predicts the shape and size of the critical nucleus by using a variational approach. Contrary to the classical nucleation theory, the model predicts the existence of a critical temperature of superheating and offers a simple formula for its calculation. The model is tested against molecular dynamic simulations in which liquid nuclei at a superheated boundary were obtained by an adiabatic trapping procedure.

Two important facts are observed in the communicational processes in the last two decades. The first one is the mass use of the computers on a global scale digital support and the second one is the connection between them the net. Both facts were accompanied by significant changes in the interface between man and machine. The wide spread of the computer had its beginning connected with the adoption of the graphic interface rather than the command-line interface and also the assimilation of the mouse. The growth of the net internet also was influenced by an interface change, when Mosaic appeared in 1993. The early internet, basically formed by textual information starts to work in a multimedia way, with sound and image along with the text. This project intends to analyze the unfolding of these two facts, by means of reading and analysis of some aspects of the digital culture and net culture, as well as to raise concepts and characteristics pertinent to these contexts for the development of new interfaces that can represent a new step or progress in an interaction form. More than ten years have passed and the signs of these changes are more and more evident and intricate in our social and cultural daily life. The discussion about the needs for new interfaces is already significant as Steven Johnson, Richard Grusin, Jay David Bolter, Lev Manovich, Giselle Beiguelman and Peter Weibel put it. This work is based greatly, besides the authors above, in the points of view of Alexander Galloway and Howard Rheingold. The relevance of this study is more evident as the digital interfaces are more and more present in so many social layers and activities, but now they have their capacity questioned. Todays graphic interface still has some of their characteristics attributed in the 70s, and developed to work basically with a quantity of information restricted to one computer. At the same time it accesses and manipulates a much bigger quantity of information, come from and distributed to billions of computers

A difusão do computador teve início, em grande parte, pela adoção de uma interface gráfica em detrimento da linha de comando e pela incorporação do mouse. O crescimento da rede internet deu-se, também em grande parte, através de uma mudança de interface, com o surgimento do Mosaic em 1993. Antes basicamente constituída de informação textual, a internet passa a trabalhar de forma multimídia, com textos, sons e imagens.

▼ Although wildland fires are a beneficial ecosystem process, they can also cause destruction to human-built structures and infrastructure, as evidenced by disasters such as the Fort McMurray fire in 2016 and the Slave Lake fires in 2011. This type of destruction occurs in the “wildland-urban interface” (WUI), which are areas where homes or other burnable community structures meet with or are interspersed within wildland fuels. In order to mitigate destructive WUI fires, basic information such as the location of these areas is required. Unfortunately, Canada does not have a national scale, high-resolution WUI map for use in research or fire management, which hinders our ability to study fires in WUI areas. Therefore, this study focused on defining and mapping the WUI for the national area of Canada, and analysed their spatial distribution and relationships with fuels, structures, and fires. Furthermore, two additional national maps were produced and analysed: a “wildland-industrial interface” (WII) map and an “infrastructure interface” map. These additional maps focus on the interface of wildland fuels with industrial structures (e.g. oil and gas or mining structures) for the WII, or with infrastructure values (e.g. transmission lines, railways, or roads) for the infrastructure interface. This study presents the first maps of these two interface types for anywhere in the world. Industrial structures and infrastructure are not traditionally defined as part of the WUI, but may require protection from fires and are important emerging issues. All three interface types (WUI, WII, and infrastructure interface) were defined as areas of wildland fuels which are within a variable-width buffer (maximum distance: 2400 m) from potentially vulnerable structures or infrastructure. Nationally, it was found that Canada has 32.3 million ha of WUI (3.8% of total national land area), 10.5 million ha of WII (1.2%), and 109.8 million ha of infrastructure interface (13.0%). Interface areas are typically most dense in the southern portion of the country (with the exception of the prairies and southern Ontario). Provinces with the largest amounts of interface include: Quebec, Ontario, Alberta, and British Columbia. However, the eastern provinces of Nova Scotia, New Brunswick, and Prince Edward Island have the highest densities of interface (interface as % of land area). Interface areas were also found to have higher than average hazardous fuel cover types, but lower than average area burned by wildfire. The results of this study, and in particular the interface maps, provide a baseline for future research, including fire risk mapping, change detection, and future predictions of interface areas. The maps produced in this study also have a wide variety of practical applications, including various topics in wildfire mitigation (e.g. FireSmart and industrial fire regulations), long-term planning (e.g. city planning and insurance), and wildfire decision support (e.g. fire prioritization and risk modelling).

▼ Metal oxides have numerous applications in our everyday lives and in most of these applications their interaction with water is inevitable. Hence, it is important to understand the interactions that occur at the water/metal oxide interfaces. In this dissertation, we have used ab initio molecular dynamics simulations to study these interactions. In particular, we will study the (110) surfaces of the commonly occurring natural polymorphs of titanium dioxide (TiO2) and tin dioxide (SnO2) known as rutile and cassiterite, respectively. A detailed analysis is presented for the structure of water above the rutile (110) surface. We find three distinct layers of water that are identified as L1, L2 and L3. The water molecules in L1 layer are covalently bonded with the metal atoms in the surface. The L2 layer is highly structured, which is in good agreement with the X-ray studies. The water molecules in this layer adsorb at two well-defined sites. The most prominent location is above and around the bridging oxygen. The other site is located above and between the two terminal oxygens from the L1 layer. The water molecules in the L3 layer do not show any specific adsorption preference. We show that the preferential adsorption sites, in L2 water layer, are produced by strong hydrogen bonds (H-bonds) between the surface and the water layer above the surface. The strength of these H-bonds is estimated from the broadening of the corresponding stretching mode of the vibrational band. The total vibrational spectrum from our ab initio simulations is in excellent agreement with those obtained from the inelastic neutron scattering experiments. We compare the proton jump processes in the hydration layer on both rutile (110) and cassiterite (110) surfaces. A set of five simulations is done, for both surfaces, to remove the effect of initial configuration on the simulation results. These simulations differ in the dissociation level of the adsorbed water molecules in the initial configurations. We find that all five simulations equilibrate to ~25% and ~60% water dissociation level on rutile and cassiterite, respectively. This dissociation level is dynamical and both surfaces exhibit proton jumping events for the whole time of the simulation and throughout the whole surface. The cassiterite surface has three times higher proton jumping events than rutile surface. The higher proton jump activity on cassiterite is produced by stronger H-bond between the surface and the water layer above the surface. We find that the stronger covalent and ionic interaction, due to the difference in the electronic structure, leads to stronger H-bond on cassiterite. In general, we find that the H-bonds are stronger on cassiterite than on rutile surface. Among these, the bridging oxygen atoms form the strongest H-bonds between the surface and the hydration layer. Thus, the cassiterite surface has the highest proton jump activity, around 10 times greater than the rutile surface. Another surface property that provides insight into the interaction of the water with… Advisors/Committee Members: Jorge Osvaldo Sofo, Dissertation Advisor/Co-Advisor, Jorge Osvaldo Sofo, Committee Chair/Co-Chair, Renee Denise Diehl, Committee Member, Reka Z Albert, Committee Member, Coray M Colina, Committee Member.
