Abstract:
We examined tRNA flexibility using a combination of steered and unbiased molecular dynamics simulations. Using Maxwell's demon algorithm, molecular dynamics was used to steer X-ray structure data toward that from an alternative state obtained from cryogenic-electron microscopy density maps. Thus, we were able to fit X-ray structures of tRNA onto cryogenic-electron microscopy density maps for hybrid states of tRNA. Additionally, we employed both Maxwell's demon molecular dynamics simulations and unbiased simulation methods to identify possible ribosome-tRNA contact areas where the ribosome may discriminate tRNAs during translation. Herein, we collected >500 ns of simulation data to assess the global range of motion for tRNAs. Biased simulations can be used to steer between known conformational stop points, while unbiased simulations allow for a general testing of conformational space previously unexplored. The unbiased molecular dynamics data describes the global conformational changes of tRNA on a sub-microsecond time scale for comparison with steered data. Additionally, the unbiased molecular dynamics data was used to identify putative contacts between tRNA and the ribosome during the accommodation step of translation. We found that the primary contact regions were H71 and H92 of the 50S subunit and ribosomal proteins L14 and L16.

Abstract:
Medical simulation is a widely used training modality that is particularly useful for procedures that are technically difficult or rare. The use of simulations for educational purposes has increased dramatically over the years, with most emergency medicine (EM) programs primarily using mannequin-based simulations to teach medical students and residents. As an alternative to using mannequin, we built a 3D printed models for practicing invasive procedures. Repeated simulations may help further increase comfort levels in performing an emergency department (ED) thoracotomy in particular, and perhaps this can be extrapolated to all invasive procedures. Using this model, a simulation training conducted with EM residents at an inner city teaching hospital showed improved confidence. A total of 21 residents participated in each of the three surveys [(1) initially, (2) after watching the educational video, and (3) after participating in the simulation]. Their comfort levels increased from baseline after watching the educational video (9.5%). The comfort level further improved from baseline after performing the hands on simulation (71.4%).

Uma estrutura que pode autorregenerar em condições ambiente é um desafio enfrentado atualmente e é uma das áreas mais promissoras na ciência de materiais inteligentes. O presente projeto visa a utilização de métodos teóricos para o estudo das propriedades estruturais e funcionais de nanocompósitos intrinsecamente autorregenerativos, permitindo estratégias mais eficientes para o desenvolvimento de novos materiais. As simulações são baseadas na Teoria do Funcional da Densidade (DFT). Estudamos os componentes isolados que constituem o nanocompósito funcional: diarilbibenzofuranona (DABBF), SHP e nanopartículas de (óxido de) níquel. Estudando a formação da DABBF contra a reação da arilbenzofuranona (ABF) e O2 (auto-oxidação), vemos que a reação de formação sem barreira da DABBF é preferida à auto-oxidação porque existe um processo de transferência de carga que resulta no superóxido fracamente ligado. Realizamos um estudo sistemático por meio de cálculos ab initio para investigar a reação de clusters de Ni13 com moléculas de O2. Avaliamos dinamicamente o efeito sobre as propriedades estruturais, eletrônicas e magnéticas e compreendemos o mecanismo de quimissorção do oxigênio (primeiro estágio da oxidação). Finalmente, estudamos as interações entre os oligômeros do SHP e as nanopartículas, levando ao nanocompósito autorregenerativo. Sugerimos como trabalhos futuros simular as interações entre todos esses materiais levando ao nanocompósito autorregenerativo por meio de uma abordagem multiescala via métodos DFT e de dinâmica molecular (MD).
A structure that can sustain self-healing repair under standard conditions is a challenge faced nowadays and is one of the most promising areas in smart materials science. The present project aims at the use of theoretical methods for the study of structural and functional properties of intrinsically self-healing nanocomposites, allowing improved design strategies for novel materials. The simulations are based on Density Functional Theory (DFT). We studied the isolated components that constitute the functional nanocomposite network: diarylbibenzofuranone (DABBF), SHP, and oxidated nickel nanoparticles. Studying DABBF bond formation against arylbenzofuranone (ABF) and O2 reaction (autoxidation), we see that the barrierless DABBF bond formation is preferred over autoxidation because there is a charge transfer process that results in the weakly bonded superoxide. We performed a systematic study by means of ab initio calculations to investigate Ni13 clusters reaction with O2 molecules. We evaluate dynamically the effect on structural, electronic, and magnetic properties and understand the oxygen chemisorption (first oxidation stage) mechanism. Finally, we study the interactions between SHP oligomers and the nanoparticles, leading to the selfhealing nanocomposite. We suggest as future work simulating the interactions between all these materials leading to the self-healing nanocomposite through a multiscale approach via DFT and molecular dynamics (MD) methods.

Abstract:
Au cours des dernières décennies, les attaques par canal latéral (SCA) ont démontré leur dangerosité dans la récupération des données sensibles des circuits intégrés. Parmi ces attaques, celles exploitant les rayonnements électromagnétiques des circuits intégrés sont particulièrement efficaces. En effet, les adversaires n'ont besoin de trouver qu'un seul point chaud (position de la sonde EM sur la surface du CI) où il y a une fuite exploitable pour compromettre la sécurité du circuit. En conséquence, la conception de circuits intégrés sécurisés et robustes contre ces attaques est incroyablement difficile car les concepteurs doivent garantir qu'il n'y a pas de point chaud sur l'ensemble du circuit intégré surface. Cette tâche est d'autant plus difficile qu'il n'existe pas d'outil CAO permettant de vérifier la robustesse des circuits intégrés contre EM SCA au stade de la conception, c'est-à-dire avant la fabrication. Dans cette thèse un flux de simulation permettant de reproduire EM SCA par simulation est proposé. Le Biot-Savart loi est utilisée pour modéliser le champ magnétique rayonné par des circuits intégrés entiers et une méthodologie innovante, appelé Noise-to-Add, est introduit. Ce dernier permet de pallier l'absence de bruit dans simulations et interpréter correctement les résultats des attaques par corrélation de simulation
In the last decades, side-channel attacks (SCA) have demonstrated their dangerousnessin retrieving sensitive data from ICs. Among these attacks, those exploiting EM radiationsof ICs are particularly efficient. Indeed, adversaries need to find only one hotspot (positionof the EM probe over the IC surface) where there is an exploitable leakage to compromisethe security of the circuit. As a result, designing secure ICs robust against these attacks isincredibly difficult because designers must warrant there is no hotspot over the whole ICsurface. This task is all the more difficult as there is no CAD tool allowing to verify therobustness of ICs against EM SCA at the design stage, i.e. prior to fabrication. In this thesisa simulation flow allowing to reproduce EM SCA by simulation is proposed. The Biot-Savartlaw is used to model the magnetic field radiated by entire ICs and an innovative methodology, called Noise-to-Add, is introduced. This latter allows to overcome the absence of noise in simulations and correctly interpret simulation correlation attacks results

Abstract:
The data-driven adaptive algorithms are explored as a means of increasing the accuracy of Reynolds-averaged turbulence models. This dissertation presents two new data-driven adaptive computational models for simulating turbulent flow, where partial-but-incomplete measurement data is available. These models automatically adjust (i.e., adapts) the closure coefficients of the Reynolds-averaged Navier-Stokes (RANS) k-ω turbulence equations to improve agreement between the simulated flow and a set of prescribed measurement data. The first approach is the data-driven adaptive RANS k-ω (D-DARK) model. It is validated with three canonical flow geometries: pipe flow, the backward-facing step, and flow around an airfoil. For all 3 test cases, the D-DARK model improves agreement with experimental data in comparison to the results from a non-adaptive RANS k-ω model that uses standard values of the closure coefficients. The second approach is the Retrospective Cost Adaptation (RCA) k-ω model. The key enabling technology is that of retrospective cost adaptation, which was developed for real-time adaptive control technology, but is used in this work for data-driven model adaptation. The algorithm conducts an optimization, which seeks to minimize the surrogate performance, and by extension the real flow-field error. The advantage of the RCA approach over the D-DARK approach is that it is capable of adapting to unsteady measurements. The RCA-RANS k-ω model is verified with a statistically steady test case (pipe flow) as well as two unsteady test cases: vortex shedding from a surface-mounted cube and flow around a square cylinder. The RCA-RANS k-ω model effectively adapts to both averaged steady and unsteady measurement data.

Abstract:
Este trabalho situa-se nas áreas de Sistemas Multiagentes e Geoprocessamento. Em Sistemas Multiagentes, a especificação de um sistema pode ser realizada através da modelagem do ambiente, agentes, mecanismos de interação e organização dos agentes envolvidos. Um aspecto pouco explorado, porém extremamente importante, é a modelagem e representação do ambiente em que os agentes estão situados e através do qual irão interagir. Por outro lado, o Geoprocessamento sempre enfatizou a representação de fenômenos espaciais de forma estática. No entanto, alguns fenômenos espaciais são inerentemente dinâmicos e as representações estáticas não os capturam de forma adequada. Assim, o foco principal deste trabalho é fornecer uma arquitetura, baseada em Sistemas Multiagentes, para a criação e execução de simulações na área de Geoprocessamento. Uma característica importante é a utilização de dados vetoriais, provenientes de um Banco de Dados Geográficos, na geração da representação espacial do ambiente e das entidades existentes nas simulações. Com esta forma de representação contínua e precisa, é possível criar modelos mais próximos da realidade, representando adequadamente um maior número de características. Além disto, a arquitetura permite a representação de fenômenos espaço-temporais dinâmicos, uma necessidade da área de Geoprocessamento. Focando no desenvolvimento das funcionalidades da arquitetura proposta, foi realizada uma análise das características positivas, negativas e das necessidades de algumas das principais plataformas para criação e execução de simulações baseadas em agentes. Considerando os resultados desta análise, foram criadas a arquitetura proposta e suas funcionalidades. Além disto, neste trabalho é apresentado o protótipo implementado, no qual foram realizados estudos de caso de diferentes cenários, objetivando avaliar e demonstrar o uso das funcionalidades desenvolvidas.
This work is situated in the intersection of two areas: Multi-Agent Systems and Geocomputing. In Multi-Agent Systems, the specification of a system can be achieved by the modelling of environment, agents, mechanisms of interaction and organization of the agents. Although being a very important aspect, the modelling and representation of the environment has not been yet fully explored. On the other hand, Geocomputing has always focused in the static representation of spatial phenomena. However, some spatial phenomena are dynamic on time and space and usual representation adopted in Geocomputing do not capture them well. The aim of this work is to provide an architecture, based on Multi-Agent Systems, for the development and execution of Geocomputing simulations. A very important feature of the proposed architecture is the use of vectorial data, from a Geographic Database, for the representation of the environment and the spatial entities that exist in it. Using this continuous and accurate representation form, it is possible to develop more realistic models, representing appropriately geographic features. Moreover, this architecture allows the representation of dynamic phenomena in time and space, an old need of the Geocomputing area. Focusing on the development of the features of this architecture, an analysis of some related works was realized. The development of this architecture and its features was done based on the results of this analysis. Moreover, a prototype was presented in this work, in which some case studies of different scenes were performed, aiming at the evaluation and demonstration of the developed model and its features.

A pasta de cimento 'e um material complexo, heterog¿eneo e poroso com excelentes propriedades que o tornam um aglutinante adequado para aplica¸c¿oes em constru¸c¿oes. A qualidade e a durabilidade do cimento t¿em uma forte rela¸c¿ao com a 'agua contida nele. Embora uma boa compreens¿ao das intera¸c¿oes complexas entre os poros do cimento e os flu'ýdos confinados 'e necess'aria para resolver os atuais problemas de durabilidade, at'e ent¿ao nenhum modelo foi bem sucedido na captura de todos os processos e o papel da 'agua no cimento continua a ser uma 'area de pesquisa ativa. Com o intuito de contribuir para a compreens¿ao atual da estrutura do cimento, este trabalho se concentrou no estudo dos processos din¿amicos que acontecem na nanoescala da 'agua confinada em poros de cimento. Utilizamos simula¸c¿oes atom'ýsticas que v¿ao desde primeiros princ'ýpios at'e din¿amica molecular para estudar a principal fase de hidrata¸c¿ao, ou seja, hidrato de silicato de c'alcio (C¿S¿H), modelado por uma estrutura de tobermorita com defeitos. A partir de primeiros princ'ýpios, investigamos a morfologia da superf'ýcie da tobermorita a qual rege as intera¸c¿oes da 'agua com o modelo C-S-H. Demonstramos que a tobermorita forma cristais pseudo-hexagonais e a faceta mais est'avel 'e a (004). A fim de explorar sistemas maiores, checamos a transferabilidade do potencial cl'assico CLAYFF na descri¸c¿ao dos componentes do cimento atrav'es de um estudo comparativo entre simula¸c¿oes de mec¿anica molecular e DFT. Embora as frequ¿encias calculadas com DFT e CLAYFF sejam diferentes, as propriedades estruturais e termodinâmicas apresentam grande concord¿ancia, indicando que o potencial CLAYFF 'e adequado para nossos c'alculos. Um par¿ametro importante para quantificar a din¿amica da 'agua no nanoconfinamento 'e o tempo de relaxa¸c¿ao T2. Para validar a metodologia implementada na determina¸c¿ao te'orica do tempo de relaxa¸c¿ao T2, realizamos simula¸c¿oes para a 'agua confinado dentro de nanoporos de calcita (1¿6 nm). Observamos que a din¿amica translacional 'e a principal respons'avel pela relaxa¸c¿ao de spin das mol'eculas de 'agua pr'oximas 'a superf'ýcie. O tempo de relaxa¸c¿ao T2 para mol'eculas de 'agua adsorvidas na superf'ýcie 'e menor e independente do tamanho de poro, no entanto, uma relaxa¸c¿ao de spin do tipo bulk 'e observada no centro dos poros maiores que 3 nm. Buscando elucidar as diversas propriedades da 'agua nanoconfinada em poros C¿S¿H, dividimos nosso estudo em tr¿es partes. Inicialmente, nos dedicamos a compreender os efeitos de confinamento da 'agua entre camadas (< 1 nm) e poros de gel (1¿5 nm) do modelo C-S-H, assim como suas influ¿encias nas intera¸c¿oes de superf'ýcie. A natureza hidrof'ýlica da superf'ýcie C¿ S¿H 'e evidenciada pela din¿amica lenta da 'agua que interage diretamente com a superf'ýcie. Entre as camadas, a 'agua se encontra praticamente im'ovel e exibe propriedades similares aquelas observadas em 'agua super-resfriada. Na sequ¿encia, investigamos o transporte da 'agua dentro da pasta de cimento implementando a relaxa¸c¿ao de troca do tipo 2D T2¿T2 RMN entre poros de gel com 1 nm e 4 nm conectados entre si. Nossos resultados mostraram que h'a trocas de mol'eculas de 'agua entre poros com um tempo caracter'ýstico de troca de 18 ns. Finalmente, conclu'ýmos nossos estudos considerando a natureza particulada do C¿S¿H a fim de estabelecer uma conex¿ao entre os fen¿omenos observados nas escalas nano e meso. Demonstramos que a 'agua confinada dentro do ambiente C¿S¿H edge-edge apresenta uma din¿amica semelhante ao caso das superf'ýcies planares.
Cement paste is a complex, heterogeneous and porous material with outstanding properties that make it a suitable binder for construction applications. The quality and durability of cement have a strong relationship with the water contained in it. While a good understanding of the complex interactions between the cement pores and the confined fluids is necessary to solve the current durability issues, no single model has been successful in capturing all the processes so far and the role of water in cement still remains an area of active research. To contribute to the current understanding of cement structure, this work has focused on studying the dynamical processes happening at the nanoscale of water confined in cement pores. We employ atomistic simulations ranging from first principles to molecular dynamics to study the main hydration phase, i.e calcium silicate hydrate (C¿S¿H), modeled by a defected tobermorite structure. Starting from first principles, the surface morphology of tobermorite which governs the interactions of water with the C¿S¿H model was investigated. It was shown that tobermorite forms pseudohexagonal crystals and the most stable facet is the (004). To upscale the calculations, the transferability of CLAYFF in the description of cementitious materials was tested through a comparative molecular mechanics and DFT study. Although the frequencies calculated with DFT and CLAYFF differ, the structures and thermodynamic quantities agree quite well, making CLAYFF a reasonable potential for our cement calculations. An important parameter to quantify water dynamics in nanoconfinement is NMR T2 relaxation time. To underpin the implemented methodology for theoretical determination of T2 relaxation time, simulations were performed for water confined within calcite nanopores (1¿6 nm). It was revealed that translational dynamics are the main contribution to spin relaxation of near surface water molecules. The T2 relaxation time for water molecules directly adsorbed on the surface is short and pore size independent, however a bulk¿like spin relaxation is observed at center of pores larger than 3 nm. To disentangle the diverse properties of water nanoconfined in C¿S¿H pores, the study of water within C¿S¿H was subdivided into three parts. The first part was dedicated to understanding the relative effect of the C¿S¿H surface and progressive confinement to water confined in the interlayer (< 1 nm) and gel pores (1¿5 nm) of C¿S¿H model. The hydrophilic nature of the C¿S¿H surface is evidenced by the slow dynamics for the water interacting directly with the surface. Within the interlayer, water is highly immobile and exhibits similar properties as those observed in supercooled water. Next, transport within cement paste was investigated by implementing 2D T2¿T2 NMR exchange relaxation between a 1 nm and 4 nm gel connected pores. We showed that there is water exchange in gel pores quantified by an exchange time of 18 ns. Lastly, the particulate nature of C¿S¿H is taken into consideration to facilitate bridging the gap between the atomistic and the mesoscale cement understanding. It was shown that water confined within the C¿S¿H edge¿edge environment portrays similar dynamics as in the C¿S¿H planar surfaces.

Abstract:
A Tomografia por Emissão de Pósitrons (PET) está se definindo como um dos métodos preferidos para diagnóstico e seguimento de inúmeras doenças em Oncologia, Neurologia e Cardiologia. Esta modalidade é realizada com sistemas dedicados e sistemas baseados em câmaras de cintilação, que podem ser também usados em tomografia por emissão de fótons únicos (SPECT). Neste trabalho, efetuamos uma avaliação dos fatores que favorecem a quantificação em imagens PET com câmaras de cintilação em coincidência, caracterizadas por urna menor sensibilidade em relação a sistemas dedicados. Avaliamos as condições de quantificação de imagens sob os modos 2D e 3D de aquisição, obtidas por métodos de reconstrução 2D e 3D diversos e correções associadas. Dados de aquisição foram simulados por método de Monte Carlo empregando parâmetros realistas. Objetos de interesse diversos foram modelados. Imagens foram reconstruídas pelos métodos FBP, ART, MLEM e OSEM e consideramos correções de sensibilidade, normalização de detector, espalhamento e atenuação de radiação. Estabelecemos uma metodologia de avaliação de detectabilidade e recuperação de contrastes em imagens que contemplam, a partir de dois parâmetros mensuráveis, os aspectos mais relevantes em quantificação. Análises visuais também foram consideradas. Verificamos que o modo 3D é mais adequado que 2D na recuperação de baixos contrastes no objeto com a aplicação das correções selecionadas. A detectabilidade de pequenas estruturas está limitada pelos efeitos de volume parcial e pela resolução espacial finita dos sistemas de detecção. Os métodos ART, MLEM e, em particular, OSEM com 8 subconjuntos, apresentam-se adequados para estudos quantitativos no modo 3D. Os parâmetros definidos para avaliação podem ser empregados como indicadores de condições propícias a estudos quantitativos.
Volumetric reconstruction in gamma camera based PET imaging Positron Emission Tomography (PET) is considered as a very useful tool for diagnosing and following several diseases in Oncology, Neurology and Cardiology. Two types of systems are available for this imaging modality: the dedicated systems and those based on gamma camera technology. In this work, we assessed a number of factors affecting the quantitation of gamma camera based PET imaging, characterized by a lower sensitivity compared to those of dedicated systems. We also evaluated image quantitation conditions under 2D and 3D acquisition/reconstruction modes, for different reconstruction methods and associated corrections. Acquisition data were simulated by Monte Carla method, using realistic parameters. Several objects of interest were modelled. We reconstructed slices and volumes using FBP, ART, MLEM and OSEM and also included four corrections: detector sensitivity, detector normalization, scatter and attenuation of annihilation photons. We proposed a method to assess detectability and object contrast recovery by using two measurable parameters. Visual analysis was also considered. We found that 3D mode is more effective than 2D for low contrast recovery when the selected (J corrections are applied. Detectability of small structures is limited by partial volume effects and device finite spatial resolution. ART, MLEM and specially 8-subsets OSEM are the most adequate methods for quantitative studies in 3D mode. The parameter that we have defined may also be used as indicators of suitable conditions for quantitation in images.

Abstract:
O presente trabalho apresenta uma proposta de desenvolvimento e aplicação de um programa de simulação computacional usando o software MatLab/Simulink 6.0 como ferramenta de Engenharia Automotiva, aplicando-a para o estudo do desempenho de veículos comerciais rodoviários (caminhonetes, caminhões e ônibus) em movimentos acelerados e em regime permanente. O programa de simulação considera o motor mapeado em torque e consumo específico e o sistema de transmissão do eixo do motor às rodas motrizes e se conecta a outro programa de simulação existente e desenvolvido no Laboratório de Computação Veicular da EESC-USP. Para as simulações foram utilizados os dados de um veículo comercial característico submetido a várias situações de movimento acelerado em pista horizontal e inclinada, quando foram obtidos dados importantes como consumo médio e instantâneo do veículo para cada um dos cenários previstos. Outros dados como os espaços percorridos, as velocidades, as acelerações, as rotações do eixo do motor, o escorregamento parcial dos pneumáticos e outros são apresentados neste trabalho. Adicionalmente, o programa de simulação mostra potencial de uso nas fases de projeto, desenvolvimento e otimização dos veículos comerciais, podendo reduzir custos com a diminuição dos prazos e testes necessários para a avaliação do desempenho do veículo em pista de provas. Apresenta também potencial de aplicação na melhor especificação do veículo a ser comprado pelo frotista considerando as condições específicas do seu uso.
This work presents a development and application proposal of a simulation program using the software Matlab/Simulink 6.0 as an Automotive Enginnering tool, applying it for the study of the commercial vehicles performance in accelerated and uniform movement. The simulation program considers the engine maps of specific fuel consumption and torque curves and also the transmission system between the engine and the tractive wheels. The simulation program connects itself with another simulation program developed in the EESC-USP Vehicle Computation Laboratory. For the simulations were used the data of a characteristic commercial vehicle submited to various situations on horizontal and inclinated roads, when were taken relevant data like average and instant fuel consumption for each predicted scene. This work also presents vehicle operational data as engine speed, covered spaces, longitudinal velocities and accelerations, adherence and relative slip of the wheels and others. The simulation program shows a hugh potential use in the optimization, development and project phases of commercial vehicles, allowing saving of time and financial resources. The simulation program shows also a potential application in the best vehicle specification to be bought by the client considering the specific conditions of its use.

Abstract:
Neste trabalho, analisamos três modelos definidos sobre redes e governados por dinÂmicas estocásticas. Nosso principal interesse repousa no estudo das transições de fase e no comportamento crítico desses modelos. O primeiro deles é o autômato celular pobabilístico da Domany-Kinzel, ao qual aplicamos o método de expansões em série. Em seguida, estudamos o comportamento para tempos longos de alguns processos de reação-difusão por meio de simulação numérica. Tais processos podem ser relevantes para o entendimento da compactação em sistemas granulares. Finalmente, também através de dimulações numéricas, analisamos o processo de contato conservativo, que é uma versão do modelo original definida em um ensemble onde o número de partículas é conservado.
In this work, we analyzed three lattice models governed by stochastic dynamics. Our main interest lies on the study of the phase transitions and critical behavior of these models. The first of them is the Domany-Kinzel probabilistic cellular automaton, to which we applied the method of series expansions. Next, we studied the long time behavior of some reaction-diffusion processes by means of numerical simulations. Such processes may be relevant to the understanding of granular compaction. Finally, also by means of numerical simulations, we have analyzed the conserved contact process, which is a version of the original model defined on an ensemble where the number of particles is conserved.

Abstract:
L'objectif défini dans cette thèse est d’utiliser les récentes techniques de model checking probabiliste afin de vérifier des contraintes de performances sur des architectures de simulations distribuées. L'aspect probabiliste de l'approche permet à la fois de réduire la complexité du modèle et d’exprimer des contraintes de performances plus souples. Dans cette thèse nous avons dans un premier temps tenté d’utiliser le model checking probabiliste afin de formuler et de vérifier de telles contraintes de performances. Nous avons utilisé le model checker PRISM et confronté les résultats obtenus avec des données réelles provenant de simulations distribuées. Ceci a permis de révéler une difficulté fondamentale de cette démarche : il est difficile de choisir les coefficients du modèle pour que les résultats obtenus par le model checker coïncident avec la réalité. En clair, le modèle doit être réaliste. Afin de surmonter cette difficulté nous avons d’abord utilisé des algorithmes d'approximation qui ont permis d’obtenir des modèles plus réalistes mais sans structure, les rendant difficilement compréhensibles et manipulables. Afin de remédier à ce problème nous avons adapté un de ces algorithmes d’approximation, permettant d’induire des distributions de type phase à partir d’un ensemble de temps d’absorption, pour lui permettre d’opérer sur des modèles décrit dans l’algébre PEPA, un langage de modélisation basé sur une approche compositionnelle. L'algorithme a ensuite été étendu afin de fonctionner avec des exécutions partiellement observables au lieu de temps d’absorption, permettant ainsi de travailler sur des modèles PEPA sans état absorbant. Les expérimentations s’appuient sur le logiciel EMPEPA, distribué librement en Open-source, développé dans le cadre des travaux de thèse, et implantant en particulier ces deux algorithmes.

Abstract:
A base evolucionaria da senescência é um problema biológico de longa data. Senescência, no sentido da deterioração progressiva de um organismo, distingue-se de envelhecimento, ou a mera passagem do tempo. Como, pelo menos em mamíferos, senescência e envelhecimento ocorrem simultaneamente, os termos são tomados erroneamente como sinônimos. A senescência parece explicada pelo desgaste do organismo, levando a um paradoxo frente aos mecanismos de seleção natural, pois, sendo a maquinaria biológica portadora de mecanismos de auto-reparo, esperáramos o aprimoramento destes, com gradual eliminação da deterioração associada ao envelhecimento. Historicamente, procurou-se resolver este paradoxo imaginando-se que a senescência conferisse uma vantagem adaptativa, mas este argumento, que requereria distinguir os indivíduos mais velhos, é circular. A partir de meados do século XX, três hipóteses prevaleceram. O acúmulo de mutações, proposto por Medawar (1951), considera que o decaimento gradual da força de seleção com a idade favorece o acúmulo de genes deletérios expressos em idades avançadas. O antagonismo pleiotrópico, proposto por Williams (1957), defende que genes ligados a características benéficas e deletérias poderiam ser, em certas condições, favoravelmente selecionados. Finalmente, a teoria da soma descartável, proposta por Kirkwood (1975), sugere que organismos são favoravelmente selecionados quando investem em Reprodução mesmo em detrimento da manutenção somática. A descrição dinâmica dos fenômenos envolvidos em cada hipótese e a contribuição relativa de cada uma é, ainda, objeto de debate. O presente trabalho visa ao desenvolvimento de modelos computacionais estocásticos que mimetizem as condição para cada uma delas. Iniciamos o desenvolvimento pela ordem histórica, testando o mecanismo proposto por Medawar, que é o objeto desta tese. A teoria do acúmulo de mutações encontrou críticos que sugerem que este mecanismo levaria os efeitos deletérios à sincronia em idades muito avançadas, tornando a senescência um fenômeno repentino e limitado a tais idades. Isto contrariaria a observação experimental, pois a senescência é um processo gradual e mesmo animais silvestres exibem fenômenos senescentes detectáveis precocemente. Para manter a modelagem compatível com o conhecimento atual sobre genética de populações, incluímos neste modelo os efeitos da seleção, da deriva genética e de diferentes taxas de mutação. Como previsto, em nossas simulações a moda das idades de manifestação dos genes deletérios se estabilizou apenas em idades muito avançadas, próximas ao término das distribuições etárias. Também como esperado, estas distribuições terminaram em idades mais precoces nos cenários de maior mortalidade extrínseca. No entanto, em todas as nossas simulações, houve distribuição mais ou menos larga das idades de manifestação em torno da moda. A distribuição alargou-se com o aumento da probabilidade de mutação, sugerindo que as idades de manifestação podem espalhar-se ao longo da vida, chegando, em alguns cenários, à manutenção de alelos com manifestação ao nascer. Isto é compatível com o modelo de alelos ineptos utilizado em genética populacional, em que diferentes variantes concorrem até atingirem um equilíbrio entre seleção, mutação e deriva genética. Considerando-se o critério demográfico para senescência, em que a mortalidade aumenta em função da idade, podemos dizer que as nossas simulações evoluíram populações senescentes. Embora nossos dados não contrariem as outras teorias da senescência, claramente mostram que a perda da força de seleção não é um mecanismo suficiente para a senescência. Especialmente com alelos de expressão tardia, as forças de deriva podem ser preponderantes e devem ser levadas em conta para explicar a evolução da senescência
The evolutionary basis of senescence is a long standing biological problem. Senescence, in the sense of progressive deterioration of an organism, is distinguished from aging, or the mere passage of time. Because, at least in mammals, aging and senescence occur simultaneously, the terms are wrongly taken as synonyms. Senescence seems explained by the wear of the organism, leading to a paradox facing the mechanisms of natural selection, because, being the biological machinery bearer of self-repair mechanisms, we would expect their improvement, with gradual elimination of the deterioration associated with aging. Historically, there were attempts to resolve this paradox by supposing that senescence confers an adaptive advantage, but this argument would require that older individuals were previously distinct from younger ones and is, therefore, circular. From mid-twentieth century, three hypotheses have prevailed. The mutation accumulation, proposed by Medawar (1951), proposes that the gradual decay of the force of selection with age favors the accumulation of deleterious genes expressed in advanced ages. The antagonistic pleiotropy, proposed by Williams (1957), argues that genes linked to benecial and deleterious traits could, under certain conditions, be favorably selected. Finally, the disposable soma theory, proposed by Kirkwood (1975), suggests that organisms are positively selected when they invest in reproduction even at the expense of somatic maintenance. The dynamic description of the phenomena involved in each mechanism and the relative contribution of each one is still debated. The present work aims to develop stochastic computer models that mimic the conditions for each. We started by historical order, testing the mechanism proposed by Medawar, which is the subject of this thesis. The theory of mutation accumulation found critics who suggest that this mechanism would cause deleterious eects to synchronize in very advanced ages, causing senescence to be a sudden phenomenon limited to these ages. This is a contradiction with the experimental observation, because senescence is a gradual process and even wild animals exhibit senescent phenomena detectable in young ages. To keep the model consistent with the current knowledge on population genetics, this model included the eects of selection, genetic drift and dierent mutation rates. As predicted, in our simulations the mode of the age of onset of deleterious genes stabilized only in very advanced ages, near the end of the age distribution. Also as expected, these distributions ended in earlier ages in scenarios of higher extrinsic mortality. However, in all our simulations, there was more or less wide distribution of ages of onset around the mode. The distribution is enlarged with increased probabilities of mutation, suggesting that the ages of onset may spread throughout life, including, in some scenarios, the maintenance of alleles with manifestation at birth. This is consistent with the innite alleles\' model used in population genetics, where dierent variants compete until achieving an equilibrium between selection, mutation and genetic drift. Considering the demographic criterion for senescence, in which mortality increases with age, we can say that our simulations evolved senescent populations. Although our data do not con ict with the other theories of senescence, they clearly show that the falling force of selection with age is not a sucient mechanism for senescence. Especially with alleles of late expression, the forces of genetic drift may be prominent and should be taken into account to explain the evolution of senescence

Abstract:
High Performance Computing (HPC) systems are used to solve a number of complex issues in different fields of knowledge. However, these platforms have been rapidly evolving in size and complexity; and ensuring efficiency in managing applications (jobs) has become a challenge. Typically, this management involves scheduling heuristics that consist of functions to order the jobs. In this work we evaluate the limits of regression methods for creating scheduling heuristics. Our results show that the simplest heuristic led to the most efficient scheduling, while the more complex heuristics showed instabilities due to multicollinearity.

In this paper, we propose a methodology for estimating the execution time of simulations driven by multiscale numerical methods. The methodology explores the idiosyncrasies of multiscale simulators to reduce the uncertainty of predictions. We use the multiscale hybrid-mixed (MHM) finite element method to validate our methodology. We compare our proposed technique with prediction models automatically selected and calibrated by Auto-WEKA. We show that the models obtained with our technique are competitive when compared with the models coming from Auto-WEKA, being interpretable and with much less computational effort during the learning process.

Abstract:
Processor-in-Memory (PIM) architectures, such as the Hybrid Memory Cube (HMC), are emerging nowadays as a solution for processing large amount of data directly inside the memory. In this area, several researchers are proposing and evaluating new instructions and new PIM architectures. For such evaluations, trace-driven simulators, as the Simulator of Non-Uniform Cache Architectures (SiNUCA), are commonly used in order to model these new proposed systems. Such simulators provide fast prototyping of new architectures, while it requires the researcher to write simulation traces manually when evaluating new Instruction Set Architecture (ISA) proposals, which is an time consuming and error prone task. In this work, we propose a methodology for fast generation of simulation traces focused on HMC architecture, which consists on a high-level Intrinsics-HMC library and a modification inside the trace-generator tool from SiNUCA. Our proposal enables the researchers to write high level code in C/C++ languages using our library, which mimics the behavior of HMC instructions. These codes can be compiled and executed in traditional x86 architectures for verification. After ensure the code is correct and working, the user can use our modified version of SiNUCA-Tracer to translate HMC functions into HMC instructions know by the simulator, providing a convenient solution to generate traces and fast simulations of new PIM architectures. Results using the proposed technique applied on database application kernels show the correct translation and simulation of new HMC instructions using SiNUCA.
