The main contributions of this thesis include two points: firstly, we originally establish Complex STM to semi-analytically calculate the mode profiles of multi-layer planar waveguide terminated with both PML and PRB ; secondly, although CMMM has been generally applied to the simulation of waveguide facets, Bragg gratings, etc[52-53], we for the first time demonstrate that CMMM can also be utilized for the modeling of couplings of radiation field outgoing perpendicularly to the waveguide axis with an incident wave launched in the examples of high-index-contrast waveguide crossings and corners. CMMM is proved to be able to estimate the field profiles and power flows accurately through the validation with FDTD.

Optical waveguides are basic building blocks of high-density photonic integrated circuits and play crucial roles in optical access networks, biomedical system, sensors and so on. Various kinds of dielectric waveguides apply the total internal reflection condition to transmit optical field [9] and even more complicated structures based on waveguide interconnects, Bragg grating, photonic crystals are actively developed by corporations and academic institutes. Especially, the fast developing pace of Metal-Organic Chemical Vapor Deposition (MOCVD), Molecular Beam Epitaxy (MBE) and other fabrication techniques has predicted the increasing complication and thus more advanced function of modern optics integrated circuits. Under such circumstances, convenient and accurate modeling and simulation schemes are necessary for the exploration, designing and optimization of photonic devices, systems and networks before the time-consuming and expensive fabrication process. The thesis summarizes several frequency-domain modeling schemes for the calculation of mode profile or beam propagation in 2D dielectric waveguide. The thesis mainly covers conventional Smooth Transition Method (STM), High Order Finite Difference (HOFD) scheme, Complex STM, and Complex Mode Matching Method (CMMM) based on the 2D waveguide model terminated with Perfect Matching Layer (PML) and Perfect Reflection Boundary (PRB). The mode spectrums and modal patterns obtained from Complex STM are compared with those of HOFD, and the simulation of waveguide crossings and corners with CMMM is validated with Finite-Difference-Time-Domain (FDTD) Method.

▼ Phase separation has a significant impact on many chemical engineering applications, and since the phase transition of asymmetric one–component fluid or mixture interfaces can be gradual, or smooth, further analysis is warranted for fluid separation on the mesoscale. Complete scaling is applied to account for fluctuations in the critical region and to model the interfacial profiles of one–component and dilute binary mixtures, as well as calculate the curvature correction to the surface of tension (or Tolman length). Well–established symmetric profiles were selected for the order parameter and thermal scaling densities for use in complete scaling to model these asymmetric fluids. Real fluid asymmetry was applied to these profiles though the scaling coefficients of one–component fluids. Scaling coefficients for mixtures were introduced through the experimental critical parameters of the specific mixture; characteristics accounted for included consideration of the difference in molar volume between solvent and solute, changes in critical temperature and pressure with concentration as well as the Krichevskii parameter. Flory theory was used to approximate the scaling coefficients in dilute polymer solutions to determine the Tolman length. These results indicated that the Tolman length diverges near the critical point of separation and with an increasing degree of polymerization. As an infinite degree of polymerization is approached, the Tolman length becomes half of the width of the interface. Since fluid behavior near the critical point of separation is universal, many of the theoretical expressions shown in this work can be applied to other asymmetric systems. The results of this analysis showed that a large difference in molecular volume led to a higher degree of fluid asymmetry in polymer solutions. The concentration of added solute, specifically in dilute n–heptane–ethane solutions resulted in increased fluid asymmetry in density profiles, as well as a shift toward the density of the added solute. When considering dilute mixtures of aqueous n–hexane and n–heptane–ethane solutions, a slight increase in concentration of solute, coupled with an increasing temperature distance to the critical point of separation, yielded the greatest increase in fluid asymmetry in concentration profiles.

▼ Emotion regulation is an important transdiagnostic symptom of psychopathology and a key treatment target for intervention. It has been extensively researched in psychology using multiple measurement methods. Despite the diverse methodological approaches used to measure emotion regulation, little research has examined the correspondence of those measures. This multi-study dissertation investigated how different measures of emotion regulation correspond in women with and without Borderline Personality Disorder (BPD) to generate preliminary ideas of how the relationships among these measures may be used to better understand mental disorders and improve treatment. The first study examined correspondence among self-report, behavioral, and physiological measures of emotion regulation and emotion dysregulation in 50 women with BPD and 55 non-disordered controls. Latent profile analyses were used to identify unique profiles of emotion regulation and dysregulation. Results showed that few measures of emotion regulation correlated with each other and that differences between groups were primarily found only in self-report measures. Three latent profiles of emotion regulation and four latent profiles of emotion dysregulation were identified in the full sample, demonstrating unique patterns among the relationships of these measures. The second study expanded on the neuroimaging literature of emotion reactivity and regulation in women with BPD, as well as, examined the relationships of neural findings with other measures of emotion reactivity and regulation. A sample of 32 women, 17 with BPD and 15 non-disordered controls viewed negative and neutral images while undergoing functional magnetic resonance imaging and were instructed to either view, suppress, or reappraise. Results did not show hypothesized group differences in limbic hyperreactivity or prefrontal control regions. Activation unique to suppressing negative images was related to several measures, including self-report of increased anger and of dysfunctional coping skills. Findings of these two studies demonstrate that multi-method approaches are important in the study of emotion regulation as different measurement methods do not always correspond with each other and therefore a single measurement does not provide an accurate picture of the emotion regulation system as a whole. This research has important clinical implications in the understanding of assessment and treatment of individuals who experience difficulties in emotion regulation.

▼ By analyzing the last years of software development evolution, it is possible to observe that the involved technologies are increasingly focused on the definition of models for the specification of the intended software products. This model-centric development schema is the main ingredient for the Model-Driven Development (MDD) paradigm. In general terms, the MDD approaches propose the automatic generation of software products by means of the transformation of the defined models into the final program code. This transformation process is also known as model compilation process. Thus, MDD is oriented to reduce (or even eliminate) the hand-made programming, which is an error-prone and time-consuming task. Hence, models become the main actors of the MDD processes: the models are the new programming code. In this context, the interoperability can be considered a natural trend for the future of model-driven technologies, where different modeling approaches, tools, and standards can be integrated and coordinated to reduce the implementation and learning time of MDD solutions as well as to improve the quality of the final software products. However, there is a lack of approaches that provide a suitable solution to support the interoperability in MDD processes. Moreover, the proposals that define an interoperability framework for MDD processes are still in a theoretical space and are not aligned with current standards, interoperability approaches, and technologies. Thus, the main objective of this doctoral thesis is to develop an approach to achieve the interoperability in MDD processes. This interoperability approach is based on current metamodeling standards, modeling language customization mechanisms, and model-to-model transformation technologies. To achieve this objective, novel approaches have been defined to improve the integration of modeling languages, to obtain a suitable interchange of modeling information, and to perform automatic interoperability verification.

▼ The ultimate goal of this research is to develop the capability of direct numerical simulation of a flow containing numerous rigid finite size particles. In order to reach this goal, we have implemented the smoothed profile method (SPM) in the University of Iowa in-house solver, pELAFINT3D and overcame several challenges related to the method. This includes a proposed formulation for the interface thickness and many validations and comparisons with experimental data as well as with a second-order accurate sharp interface method. As one of the issues related to low-density particles is the instability, SPM has been improved by developing to a fully implicit scheme. Moreover, use of higher order integration formulation and implementation of Euler parameters have been shown to be helpful in stabilization of the calculations. To preserve the efficiency when the number of the particles increases, local mesh refinement is shown to be a very effective tool. A revised version of SPM that has only one projection step is proposed to improve the efficiency of the method. A comprehensive efficiency study is performed and it has been shown that the new method is less expensive in problems with high added mass effect when strongly coupled fluid-structure interaction schemes are used. Moreover, the code is massively parallelized using MPI and PETSc libraries. The parallelization includes I/O, operations leading to construction of the linear solver as well as the solver itself. Simulation of a particle laden flow involves particles collisions. Two novel collision models are suggested which are able to avoid particle overlapping for arbitrary shape particles. The methods are efficient as they are not involved with extra grid refinement related to implementing lubrication forces. The issue of handling continuously changing number of particles in a particle laden flow is solved by implementation of a linked list data structure for the particles. By studying a flow over a constricted region we showed that the platelets’ activation is more likely to happen for the particles that pass from the middle of the upper bump region because those particles will have longer exposure time to the high shear flow behind the bump. PDF contour of particles’ presence show the more concentrated presence of the particles near the bump. Moreover, the interaction of RBCs and platelets pushes the platelets toward the wall after the bottom wall. Advisors/Committee Members: Udaykumar, H. S. (supervisor).

▼ This thesis deals with estimation and classification problems of non-stationary processes in a few special cases.In paper A and paper D we make strong assumptions about the observed signal, where a specific model is assumed and the parameters of the model are estimated.In Paper B, Paper C, and Paper E more general assumptions about the structure of the observed processes are made, and the methods in these papers may be applied to a wider range of parameter estimation and classification scenarios.All papers handle non-stationary signals where the spectral power distribution may change with respect to time. Here, we are interested in finding time-frequency representations (TFR) of the signal which can depict how the frequencies and corresponding amplitudes change.In Paper A, we consider the estimation of the shape parameter detailing time- and frequency translated Gaussian bell functions.The algorithm is based on the scaled reassigned spectrogram, where the spectrogram is calculated using a unit norm Gaussian window.The spectrogram is then reassigned using a large set of candidate scaling factors.For the correct scaling factor, with regards to the shape parameter, the reassigned spectrogram of a Gaussian function will be perfectly localized into one single point.In Paper B, we expand on the concept in Paper A, and allow it to be applied to any twice differentiable transient function in any dimension.Given that the matched window function is used when calculating the spectrogram, we prove that all energy is reassigned to one single point in the time-frequency domain if scaled reassignment is applied.Given a parametric model of an observed signal, one may tune the parameter(s) to minimize the entropy of the matched reassigned spectrogram.We also present a classification scheme, where one may apply multiple different parametric models and evaluate which one of the models that best fit the data. In Paper C, we consider the problem of estimating the spectral content of signals where the spectrum is assumed to have a smooth structure.By dividing the spectral representation into a coarse grid and assuming that the spectrum within each segment may be well approximated as linear, a smooth version of the Fourier transform is derived.Using this, we minimize the least squares norm of the difference between the sample covariance matrix of an observed signal and any covariance matrix belonging to a piece-wise linear spectrum.Additionally, we allow for adding constraints that make the solution obey common assumptions of spectral representations.We apply the algorithm to stationary signals in one and two dimensions, as well as to one-dimensional non-stationary processes. In Paper D we consider the problem of estimating the parameters of a multi-component chirp signal, where a harmonic structure may be imposed.The algorithm is based on a group sparsity with sparse groups framework where a large dictionary of candidate parameters is constructed.An optimization scheme is formulated such as to find harmonic groups of chirps that also…

▼ Today, whether we consider the data from the internet, consumers, financial markets, a common feature emerges: all of them involve huge amounts of dynamic data that arrive sequentially and need to be understood and processed quickly. Online learning is concerned with the task of making decisions on-the-fly as observations are received. Online learning has attracted a lot of attention due to the recent emergence of large-scale applications such as online web advertisement placement, online topic-detection in social communities, online web ranking, finding shortest path for internet packet routing, email spam filtering, portfolio selection and many more. In recent years, tools from convex optimization have influenced the design of many online learning algorithms. As a result, Online Convex Optimization (OCO) has emerged as a unified abstraction, which helps in solving problems efficiently and reliably and also facilitates the theoretical analysis. In this thesis, we contribute to the development of OCO and present solutions to several complex problems motivated by real world applications.Although OCO has been studied widely, one drawback of the existing algorithms is the cost of updating model parameters with every incoming data point, especially when the number of parameters is in the order of millions or billions. An example is online portfolio selection, where changing ones portfolio aggressively everyday will incur huge amount of transaction costs. In the first part of the thesis, we present an algorithm that performs lazy updates to the parameters and show that its performance is competitive with optimal strategies, which have the benefit of hindsight. The resulting convex optimization problem is non-smooth, and we use an efficient primal-dual based alternating direction method of multipliers (ADMM) to carry out lazy updates in every step. We successfully establish the effectiveness of our online lazy updates algorithm for online portfolio selection with transaction costs with experiments on real world datasets.Several machine learning algorithms use iterative optimization methods for learning predictive models. It is difficult to know upfront, which of these routines will converge faster or give the best possible solution. This is a common problem in online portfolio selection, where there could be a number of heuristics or theoretically motivated algorithms, which suggest portfolios for each day. It is not possible for an investor to know which of these portfolio selection algorithms will make the most amount of money in a given market. In the second part of the thesis, we present two Meta Algorithms (MAs), which work by adaptively combining iterates from a pool of base optimization algorithms. We show that the performance of the MAs are competitive with the best convex combination of iterates from the base algorithms. We illustrate the effectiveness of MAs on the problem of portfolio selection in the stock market.OCO has emerged as a powerful large scale optimization approach, but much of the existing…

▼ Traditional marine propellers that are manufactured using alloys have a fixed shape. These propellers are designed to achieve the highest propulsion efficiency at the cruise condition of the vessel. However, if the flow conditions change from the vessel’s cruise condition, the propulsion efficiency reduces significantly. The objective of this thesis is to develop flexible shape-adaptive (self-morphing) blades using high performance composite materials, with particular focus on Carbon Fibre Reinforced Polymer (CFRP). By careful tailoring of fibre angle of composite layers, composite laminates can be catered to optimally change its twist under various lateral loading conditions. This special characteristic is proposed to be used for optimal change of pitch of the propeller blade based on incoming flow conditions.An in-house optimisation algorithm has been developed to search for the optimum fibre angle of each carbon fibre layer that can enable the required shape change. The optimisation algorithm uses the Genetic Algorithm (GA) coupled with the state-of-the-art Finite Element techniques such as Cell-Based Smoothed Finite Element Method (CS-FEM) and Iso-Geometric FEM. The CS-FEM uses a stable triangular element scheme, while the NURBS based iso-geometric FEM has the capability of representing the complex geometry without any mesh based approximations. The finite element techniques also take into account ply terminations of the blade and hygrothermal effects that may be present in the composite. An iterative procedure to search for the initial shape of the blades was also developed.The developed techniques were used to optimise a hydrofoil using experimental data from cavitation tunnel tests of a non-optimised hydrofoil. The optimised hydrofoil was then manufactured and was subjected to rigorous structural testing in order to ensure the strength and safety of the hydrofoil and to validate the reliability of the manufacturing technique. Additionally, hydrodynamic tests were conducted at the cavitation tunnel facility to characterise the performance of the optimised hydrofoil and compare against previously tested identical non-optimised hydrofoils. The optimised hydrofoil indeed showed more favourable results in terms of lift to drag (L/D) ratio of the hydrofoil and hydrodynamic fluctuations and uncertainties due to turbulence. The cavitation tunnel results were then validated against Fluid-Structure Interaction (FSI) simulations and were found to be in good agreement with the predictions.

En tribologie, la modélisation numérique est aujourd'hui un outil indispensable pour étudier un contact afin de pallier les limites expérimentales. Pour comprendre de mieux en mieux les phénomènes mis en jeu, les modèles ne se situent plus à une seule échelle, mais en font intervenir plusieurs, rendant plus que jamais le concept de triplet tribologique incontournable. Travaillant avec cette philosophie et en se basant sur l'approche Non Smooth Contact Dynamics, dont nous rappelons les grandes lignes, nous proposons de franchir deux cas: proposer des modèles offrant des résultats quantitatifs et mettre en place les premières pièces d'une homogénéisation au niveau du contact (VER). Dans le premier cas, l'étude du couplage éléments finis/éléments discrets au sein d'une même simulation a pour but de proposer des modèles plus "réalistes". Même si l’interface utilisée est déjà présente au coeur du contact et ne va pas évoluer, elle permet de mettre en évidence l’utilisation d’outil de mesure permettant de lier le mouvement des particules aux instabilités dynamiques et permet d’avoir des résultats qualitatifs mais aussi quantitatifs puisque la comparaison avec les taux de contraintes expérimentaux sont en très bonne adéquation. Dans le second cas, le VER sous sollicitations tribologiques est étudié afin d'étendre les techniques d'homogénéisation aux problèmes de contact afin de s'affranchir de la description des interfaces aux grandes échelles en trouvant un moyen d'homogénéiser le comportement hétérogène de l'interface et de le faire dialoguer avec le comportement continu des corps en contact en faisant remonter, dans un sens, des grandeurs moyennées à l'échelle microscopique à l'échelle macroscopique des premiers corps et dans l'autre sens, se servir des données locales à l'échelle macroscopique comme conditions limites à l'échelle microscopique.

In tribology, the numerical modeling has become an indispensable tool for studying a contact to overcome the experimental limitations. To have a better understanding of the phenomena involved, the models are no longer located at a single scale, but involve several ones, more than ever, making the concept of tribological triplet as a unavoidable concept. Working with this philosophy and approach based on the Non Smooth Contact Dynamics framework, which we remind some outlines, we propose to cross two steps~: model that can offer quantitative results and that implement the first ingredient to perform a homogenization at a contact level. In the first case, the study of coupling finite elements/discrete elements within the same simulation aims to propose models that are more "realistic". Even if the interface is already present in the contact and not going to evolves, it can highlight the use of measurement tool of spot particles via dynamic instabilities and allows to have not only qualitative results but also quantitative ones since the comparison with the experimental strain rates are in very good agreement. In the second case, the study of VER in tribological charges is…

▼ Extreme wind conditions generated near the Strait of Gibraltar (SW Spain) have given rise to the transgressive Valdevaqueros dunefield. The dune advance has resulted in gradual invasion of the adjacent road and ecosystem. Despite restoration and control activities performed within the last decades, strong east winds have favoured dune destabilisation. The current work focuses on analyzing the dune profile evolution in the long term (years), medium term (months), short term (days) and very short term (hours). Topographic data, which were collected with a total station and a differential GPS from 1995 to 2009, were interpreted from reconstructed Empirical Orthogonal Functions (EOF). This method provides an objective way to identify the mean dune profile and therefore, to recognize morphodynamic dune changes and tendencies. Wind, humidity, rain and temperature effects on the dune behaviour were analysed from the Tarifa meteorological station. Furthermore, a sand trap was placed on three different dune profile areas during 30 min, obtaining that the sand transport at the crest was twice the amount of the sand collected at the windward and near six times greater than the sand measured at the dune foot. Sand transport rates of 140 m3 m-1 year-1, 25.5–36.5 m3 m−1 month−1, 22.52 m3 m−1 day−1 and 0.93 m3 m−1 h−1 were measured for the long-term, medium-term, short-term and very short-term periods, respectively. During an eleven-year period, the average migration rate was found to be of 17.5 m year-1, although the very short term monitoring under a severe easterly sandstorm demonstrated that the dune brink was able to experience an advance of 1.75 m in only 24 h. These values were compared with the theoretical sand transport rate for Valdevaqueros dune, based on the classic Bagnold’s equation as well as other more recent formulae, to obtain a ratio between the real and the theoretical rates for each study period. These results together with the sand drift potential following the Fryberger’s method (up to 10,000 vector units) demonstrate that Valdevaqueros is a dunefield with one of the highest sand transport capacities in Europe.

▼ Direct laser deposition is a category of additive manufacturing. Its process lets metal powder be fed through a coaxial high-energy laser beam, then the melted powders drops into the molten pool and deposits on the substrate to form a cladding layer. However, the geometry of the cladding layer varies with the process parameters. For the users of the laser deposition technique, the powder mass flow rate, carrier gas flow rate, laser power and scan rate, affecting the cladding, are important parameters. If these working parameters canât be controlled, the quality of the cladding layer height and layer width would not be ensured. In addition, it might cause waste of cladding materials, workpieces, the carrier gas, and time, etc. In response to the technical challenges of the laser deposition, Stellite 6 powder chosen as cladding material and the medium carbon steel S45C selected as the substrate were used to experiment the cladding layer height and layer width of the forming parameters for improving the cladding process. First, the two-stage optimization experiment was carried out by using Taguchi method with the mass flow rate, carrier gas flow rate, laser power, and scan rate as parameters. The result shows the cladding layer height between 1.4 mm and 0.4 mm the additive layer is effective and easy to achieve under this range of layer height. Then, the cladding layer width between 2.0 mm to 3.0 mm was tested to map to the established Gaussian laser energy density model, and to find the power density threshold of the forming width boundary. According to the given laser power and scan rate, based on the Gaussian laser energy density model, the cladding layer width can be predicted. In order to meet the application requirements of laser deposition, the multi-track cladding path overlap were tested by combining the results of cladding layer height and layer width experiments. By selecting the aspect ratio between 0.25 to 0.35, and setting the overlapping rate as 25%, 30%, 35%, 40%, 45%, and 50%, experiments were carried out. As a result, the improved surface quality of multi-track cladding can be obtained by judging the maximum waviness contour value. Based on the results of this study, a set of forming parameters database from single-track to multi-track cladding is provided for direct laser deposition.

En vue d’applications aux turbines éoliennes, cette thèse vise à étendre l’utilisation des méthodes de type domaines fictifs et en particulier la méthode de pénalisation pour la simulation de l’écoulement turbulent instationnaire autour d’obstacles de géométrie complexe.La modélisation de la turbulence instationnaire à nombres de Reynolds élevés a été abordée par des approches hybrides RANS/LES telles que la (DES) et la (DDES). Afin d’améliorer la prédiction, un modèle de paroi de type TBLE a été introduit.Après une brève présentation des méthodes et des outils mis en oeuvre, des simulations2D/3D sur la configuration de cylindre et du canal sont ensuite présentées, analysées et comparées aux résultats numériques et expérimentaux.Les résultats de simulation montrent la faisabilité et l’efficacité des modèles et de la méthode de couplage (DDES/TBLE). La dernière étude se concentre sur la simulation de l’écoulement d’air autour d’un profil de pale. Les réussites et les échecs des simulations numériques sont soulignés et étudiés.En conclusion, l’étude établit les fondements pour une future application dans le cas de l’écoulement autour d’un rotor éolien en mouvement.

In the perspective of application to wind turbine design, this thesis aims to extend theuse of fictitious domain methods and in particular the method of penalization for the simulation of unsteady turbulent flows around obstacles of complex geometry. The unsteady turbulence modeling at high Reynolds numbers was studied by hybrid approaches(RANS / LES) such as (DES) and (DDES). In order to improve the prediction, a wall model based on simplified Thin Boundary Layer Equations (TBLE) was introduced.After a brief presentation of the tools and methods implemented, full 2D / 3D computations on cylinder and channel configuration are then presented, analyzed and compared to numerical and experimental results.The simulation results show the feasibility and effectiveness of the proposed models and the coupling method (DDES / TBLE).The latest investigation focuses on the simulation of the flow around the airfoil of a wind turbine. The success and fails of the computations are highlighted and explained.

▼ In the dissertation, optimal control problem for bilinear systems motivated from quantum control theory are studied. Specifically, problems of quantum feedback control, control of tumor growth dynamics and time optimal control are analyzed for bilinear systems. Feedback synthesis, receding horizon synthesis and semi-smooth Newton method are developed to solve these problems. The contents of the dissertation are outlined as follows: The first problem studied is control of quantum systems described by the linear SchrÃ‚Â¨odinger equation. Control inputs enter through coupling operators and results in a bilinear control system. Feedback control laws with switching term are developed for the orbit tracking and the performance of the feedback control laws is demonstrated by a stable and accurate numerical integration of the closed-loop system. The asymptotic properties of the feedback laws are analyzed by the LaSalle-type invariance principle. The receding horizon control synthesis is applied to improve the performance of the feedback law. The second order accurate numerical integrations via time-splitting and the monotone convergent iterative scheme are combined to solve the optimality system. The switching mechanism in the feedback law can be applied to a wide general class of control systems and feedback synthesis based on the Lyapunov stability. By using this principle, the problem of the tumor treatment, aiming at the reduction of the tumor cells population, is formulated in terms of optimal control theory as a state regulator problem and a feedback law with switching term is designed. Numerical evidence is shown to demonstrate the effectiveness of the feedback law to suppress the tumor growth. A quantum system interacts with its environment. As a consequence, quantum state subject to continuous measurement can be modeled as a nonlinear stochastic differential equation by quantum filtering theory. The problem of stochastic stabilization of quantum spin systems under the noisy environment and continuous measurement via feedback control is studied. New nonlinear control law with switching term is proposed and developed to globally stabilize the quantum spin system to an arbitrary equilibrium state. Nonnegative definite preserving properties of the density matrix to measure the quantum system is very essential and a numerical method is developed to fulfill this. Finally, time optimal and minimum effort control problems for linear and bilinear systems are studied. To overcome the difficulties of nondifferentiability in the bang-bang control, a regularized problem is formulated and the semi-smooth Newton method is applied for solving the regularized optimality system. By integrating the state and costate and variation of them in the optimality system, the nonlinear optimality system is further reduced to a nonlinear equation with some shooting parameters. The reduced Jacobian is computed for the Newton update. The initialization of the Newton method is achieved by solving a related minimum norm problem and using the… Advisors/Committee Members: Xiaobiao Lin, Committee Member (advisor), Ralph Smith, Committee Member (advisor), Zhilin Li, Committee Member (advisor), Kazufumi Ito, Committee Chair (advisor).

Cette thèse traite de la modélisation du frittage à l’échelle du Volume Élémentaire Représentatif de la pastille de matériau. L’objectif est de développer des outils numériquesde compréhension des phénomènes physiques mis en jeu lors du frittage. Le domaine d’application ciblé est la fabrication du combustible nucléaire. Une approche multi-Échelle a été mise en oeuvre. Dans un premier temps une modélisation à l’échelle d’un empilement, basée sur la méthode des Éléments Discrets, a été adoptée. Différentes études utilisant cette approche ont été proposées dans la littérature ces dernières années. Tous ces travaux utilisent une méthode discrète explicite. Si certains résultats ont pu être validés expérimentalement,une des limites vient de l’utilisation des méthodes explicites dontle pas de temps critique est très petit. Afin d’augmenter le pas de temps, la masse des particules y est augmentée artificiellement de plusieurs ordres de grandeur. Or,il a été démontré que cette pratique conduit, dans certains cas, à une diminution du réarrangement des particules au sein de l’empilement. Dans cette thèse, une méthode Éléments Discrets implicite appelée Dynamique des Contacts a été adaptée au frittage. Elle permet l’utilisation d’un pas de temps très supérieur à celui des méthodes discrètes explicites et ne nécessite pas d’augmenter artificiellement la massedes particules. La comparaison entre la Dynamique des Contacts et la Méthode des Éléments Discrets explicite montre que notre approche conduit à une représentation plus fidèle du réarrangement. Une validation expérimentale par Microtomographie X ainsi qu’une étude paramétrique sur le frittage des poudres bidispersés sont également présentées pour montrer les possibilités de l’approche discrète appliquée au frittage.La seconde partie est consacrée à une modélisation à l’échelle de deux particules parla méthode des Éléments Finis. Ce modèle repose sur une approche mécanique et vise à représenter de façon plus précise le comportement de deux particules en contact. Les diffusions au joint de grains, en surface et en volume peuvent être représentées. Pour le moment, seules les diffusions en surface et au joint de grains ont été étudiées. Si certaines optimisations restent nécessaires pour que le code soit fonctionnel, plusieurs aspects apparaissent déjà déterminants, comme la courbure de la surface à proximité du joint de grains. A l’avenir, le modèle Dynamique des Contacts du frittage pourra être complété etamélioré grâce aux éléments apportés par le modèle mécanique à l’échelle du grain.

This thesis deals with the simulation of the sintering of nuclear fuel on a pellet scale. The goal is to develop numerical tools which can contribute to a better understandingof the physical phenomena involved in the sintering process. Hence, a multi scale approach is proposed. First of all, a Discrete Element model is introduced. It aims at modeling the motion of particles on a Representative Elementary Volume scale using an original Discrete Element Method. The latter is a Non Smooth…

▼ Multi-walled carbon nanotubes (MWCNT) and 60-carbon fullerenes (C60) are important engineered nanoparticles (ENP) used across industry. Exposure to ENP potentially promotes cardiovascular detriments. The hypotheses that exposure to either MWCNT or C60 would exacerbate cardiac ischemia/reperfusion (I/R) injury and promote enhanced coronary artery contraction in response to endothelin-1 (ET-1) by a cyclooxygenase-mediated mechanism were tested. One day following intratracheal instillation of vehicle, 1, 10 or 100 [mu]g MWCNT in male Sprague-Dawley rats, hearts were isolated and mounted on a Langendorff perfusion apparatus. Hearts from animals exposed to 100 [mu]g MWCNT exhibited 3x more premature ventricular contractions during perfusion at baseline. Cardiac perfusion was stopped to induce ischemia for 20 minutes and then restarted to study injuries induced by I/R. Post-reperfusion myocardial infarction expanded 18% in the 100 [mu]g MWCNT group compared to the vehicle group. We also noted that post-ischemia cardiac release of ET-1 was increased 4-fold and coronary reperfusion flow was reduced 30% in the 100 [mu]g MWCNT group compared to the vehicle group. We next evaluated isolated coronary artery ET-1-mediated stress (mN/mm2) generation by wire myography, 24 hours after intratracheal instillation of 100 [mu]g MWCNT or vehicle. Coronary artery stress generation in response to ET-1 was increased 35% in the MWCNT group compared to the vehicle group and was dependent on cyclooxygenase/thromboxane signaling. Similar endpoints were examined following C60 exposure. We measured myocardial infarction following I/R in situ and coronary artery ET-1-mediated stress responses by wire myography, 24 hours after intratracheal or intravenous administration of vehicle or 28 [mu]g C60. Myocardial infarction expanded between 70% and 110% across all C60 groups. Coronary artery stress generation in response to ET-1 was elevated by 56% in the male intratracheal C60 group compared to the vehicle group and was dependent on cyclooxygenase signaling. ET-1 responses in all other C60 groups were not different than vehicle. These results support the potential for pulmonary exposure to carbon-based ENP to exacerbate cardiac I/R injury and promote dysfunction in coronary arteries associated with ET-1/cyclooxygenase axis. Our results indicate that therapeutic targeting of ET-1 or cyclooxygenase signaling might prevent cardiovascular detriments associated with ENP exposure.
