Texto completoThis thesis concerns the experimental study and thermodynamic modeling of the behavior of advanced fuels used in current and future generation nuclear power plants. The subject of the thesis is more precisely the study of the ternary system (U-Nd-O) and for comparison purposes of (U-Ce-O). This system is particularly representative of the fission products accumulated in the fuel for high combustion rates but also of the initial atomic substitutions in the fuel by neutron poisons, used in nuclear fuels with high enrichment levels and capable of spacing out nuclear reactor outages. The study of this system presents significant challenges due to the open conflict between thermodynamic and kinetic phenomena. It is indeed an out of equilibrium system where the long-range ordering of local structures is frustrated by the negligible of atomic transport in the cation sublattice in the range of temperatures of interest for applications. During this thesis, a review of the existing literature motivated the manufacture of samples with well-defined characteristics by powder metallurgy methods and by soft chemistry methods leading to a control of dopant distributions. The results obtained by numerous characterization techniques (XRD, SEM, TEM, XAS) on samples treated thermally under oxidizing or reducing conditions have allowed a critical re-evaluation of the phase diagrams currently used. We have modelled a new phase diagram that includes new experimental results. This allows a better knowledge of the limits of use of nuclear fuels respecting optimal safety conditions

Texto completoLiu, Jiaxiang. "Confluence properties of rewrite rules by decreasing diagrams". Thesis, Université Paris-Saclay (ComUE), 2016. http://www.theses.fr/2016SACLX044/document.
Texto completoThis thesis is devoted to the confluence of rewrite systems in the absence of termination, for applications in first-order functional languages like MAUDE or higher-order languages with dependent types, as Dedukti. In the first case, the computations on infinite data structures do not terminate, while in the second case, untyped computations do not terminate because of beta-reduction. In the case where the computations terminate, confluence is reduced to that of critical peaks, the "minimal diverging computations", made of a minimal middle term called "overlap" which computes in two different ways, resulting in a so-called "critical pair". In the case of non-terminating computations, a main result is that left-linear rewrite rules that have no critical pairs are always confluent. This suggests that the notion of critical pairs plays a key role there too, but a general understanding of the confluence of non-terminating computations in terms of critical pairs is still missing.Our investigation of confluence is based on the decreasing diagrams method due to van Oostrom, which generalizes the techniques used previously for both terminating and non-terminating computations. The method is abstract in the sense that it applies to arbitrary relations on an abstract set. It equips each step of computations with a label taken from a well-founded set. A diverging computation, called peak, has a decreasing diagram if its extremities can be joined by steps whose direction and labels satisfy some constraints with respect to the peak's rewrites and labels. The strength of this technique is its completeness, that is, any confluent relation can be equipped with a well-founded set of labels such that all peaks have decreasing diagrams. The proof of completeness is based on Klop's notion of cofinal derivations, which is an infinite derivation playing the role of a normal form when computations do not terminate.In the first part, we revise the results of van Oostrom, and propose an alternative proof that extends the method to the "modulo" case, in which computations mix rewrite steps and equational steps. The completeness result is extended as well, via a generalization of cofinal derivations and the notion of strong coherence due to Jouannaud and Kirchner.The second part of the thesis applies the decreasing diagrams method and its generalization to concrete systems rewriting terms, as well as to several open problems. The recent application to the problems of higher-order computations in dependent type theory is not part of the thesis

Texto completoInvestigations of the binary systems LiF-BiF3 and NaF-BiF3 were performed with the objective of clarifying the thermal behavior and phase equilibria of these systems and their intermediary phases, an important requisite for high-quality crystal growth. Several samples in the entire range of compositions (0 to 100 mol% BiF3) of both systems were subjected to experiments of differential thermal analysis (DTA) and thermogravimetry (TG), and also of differential scanning calorimetry (DSC). A few specific compositions were selected for X-ray diffraction to supplement the experimental data. Due to the high vulnerability of BiF3 to oxygen contamination, its volatility and propensity to destroy metal parts upon heating, it was necessary to determine the optimal conditions for thermal analysis before investigating the systems themselves. Phase relations in the system LiF-BiF3 were completely clarified and a phase diagram was calculated and evaluated via the commercial software Factsage. The diagram itself consists in a simple peritectic system in which the only intermediary compound, LiBiF4, decomposes into LiF and a liquid phase. The NaF-BiF3 system could not be completely elucidated and the phase relations in the NaF poor side (> 50% BiF3) are still unknown. In the NaF rich side, however, the possible peritectoid decomposition of the compound NaBiF4 was identified. In both systems X-ray diffraction yielded crystal structures discrepant with the literature for the intermediary phases, LiBiF4, NaBiF4 and a solid solution of NaF and BiF3 called I. The observed structures remain unknown and explanations for the discrepancies were proposed.

Texto completoThe main subject of this thesis is diagram rewriting.This is a generalisation to dimension~$2$ of word rewriting (in dimension~$1$). In a first time, we give the first convergent diagrammatic presentation of the PRO of linear maps in arbitrary field. Then we study the convergent diagrammatic presentation of matrix of isometries of $RR^n$. We focus especially on a rule similar to the Yang-Baxter equation, described by a certain map $h$. We use the confluence of criticalthe parametric diagrams, To study the algebraic properties of $h$, Finally, we present the $Sigma$-diagrams, an alternative approach for calculation in bialgebras. We illustrate this approach with examples.

Silva, Antonio Augusto Araújo Pinto da. "Thermodynamic modeling and critical experiments on the Al-Fe-Nb system". Thesis, Université de Lorraine, 2015. http://www.theses.fr/2015LORR0148.
Texto completoThe equilibrium diagrams are the starting point and the guideline to predict and control the microstructure that will form during processing materials. Despite experiments being necessary in binaries and ternaries systems, it is difficult to experimentally determine phase diagrams of higher orders systems over wide ranges of compositions and temperature. The CALPHAD (CALculation of PHAse Diagrams) method was developed in order to solve this problem. The essence is to optimize the parameters of thermodynamic models that describe the Gibbs free energies of each phase aiming to reproduce the experimental and estimated (ab-initio) data. The compound energy formalism (CEF) is widely used in order to describe phases which present several sublattices. It allows the modeling of a large variety of phases and numerous methods have been developed to treat different situations. The activities in this work developed a new approach of the CEF (NACEF) based on a mathematic analysis of the parameters which leads to a new formulation of the Gibbs free energy function evolving new independent parameters in which new independent parameters are obtained to express the Gibbs free energy. This approach was used in this work to describe the intermetallic phases with two-sublattice in which the only defect type is anti-sites (A,B)a(A,B)b. The Al-Fe-Nb system was chosen due to its importance for the manufacturing process of several families of alloys currently used, e.g. steels, light alloys, and also for the development of new materials for high temperatures application. The binaries Al-Nb and Fe-Nb were reassessed and the Al-Fe-Nb system was assessed for the first time using literature information and new experimental data
Os diagramas de equilíbrio são o ponto de partida e a diretriz para prever e controlar a microestrutura ao final do processamento de um material. Apesar de experimentos serem necessários em sistemas binários e ternários, é muito difícil determinar experimentalmente diagramas de fase de sistemas de ordens superiores numa vasta amplitude de composições e temperatura. A fim de solucionar este problema, o método CALPHAD (CALculation of PHAse Diagrams) foi desenvolvido. A essência consiste em aperfeiçoar os parâmetros de modelos termodinâmicos que descrevem as energias livres de Gibbs de cada fase de modo a reproduzir as informações experimentais ou estimadas (ab-initio). O compound energy formalism (CEF) é amplamente utilizado para descrever fases que apresentam várias sub-redes. Ele permite a modelagem de uma grande variedade de fases e vários métodos têm sido desenvolvidos para o tratamento de diferentes situações. As atividades deste trabalho ajudaram a desenvolver uma nova abordagem para o CEF (NACEF) com base em um estudo matemático dos seus parâmetros termodinâmicos que levou a uma nova formulação para função da energia livre de Gibbs envolvendo novos parâmetros independentes. Esta nova abordagem tem sido utilizado como parte do presente trabalho para modelar fases intermetálicas binárias constituídas de sub-redes cujo único defeito é do tipo anti-sítio (A,B)a(A,B)b. O sistema Al-Fe-Nb foi escolhido devido a sua importância para o processo de fabricação de diversas famílias de ligas usadas atualmente, e.g. aços, ligas leves e, além disto, é um sistema importante para o desenvolvimento de materiais para aplicações em altas temperaturas. Neste trabalho os binários Al-Nb e Fe-Nb foram reavaliados e o sistema Al-Fe-Nb foi modelado pela primeira vez utilizando as informações da literatura e novos dados experimentais

Texto completoENGLISH ABSTRACT: Binary Decision Diagrams (BDDs) are data structures that have been used to solve various problems in different aspects of computer aided design and formal verification. The large memory and time requirements of BDD applications are the major constraints that usually prevent the use of BDDs since there is a limited amount of memory available on a machine. One way of overcoming this resource limitation problem is to utilize the memory available on a network of workstations (NOW). This requires the distribution of the computation and memory requirements involved in the manipulation of BDDs over a NOW. In this thesis, an algorithm for manipulating BDDs on a NOW is presented. The algorithm makes use of the breadth-first technique to manipulate BDDs so that various BDD operations can be started concurrently on the different workstations on the NOW. The design and implementation details of the distributed BDD package are described. The various approaches considered in order to optimize the performance of the algorithm are also discussed. Experimental results demonstrating the performance and capabilities of the distributed package and the benefits of the different optimization approaches are given.
AFRIKAANSE OPSOMMING: Binêre besluitnemingsbome (BBBs) is data strukture wat gebruik word om probleme in verskillende areas van Rekenaarwetenskap, soos by voorbeeld rekenaargesteunde ontwerp en formele verifikasie, op te los. Die tyd- en spasiekoste van BBB-gebaseerde toepassings is die hoofrede waarom BBBs nie altyd gebruik kan word nie; die geheue van ’n enkele is ongelukkig te beperkend. Een manier om hierdie hulpbronprobleem te omseil, is om die gedeelde geheue van die werkstasies in ’n netwerk van werkstasies (Engels: “network of workstations”, oftewel, ’n NOW) te benut. Dit is dus nodig om die berekening en geheuevoorvereistes van die BBB bewerking oor die NOW te versprei. Hierdie tesis bied ’n algoritme aan om BBBs op ’n NOW te hanteer. Die algoritme gebruik die breedte-eerste soektegniek, sodat BBB operasies gelyklopend kan uitvoer. Die details van die ontwerp en implementasie van die verspreide BBB bilbioteek word beskryf. Verskeie benaderings om die gedrag van die biblioteek te optimeer word ook aangespreek. Empiriese resultate wat die werkverrigting en kapasiteit van die biblioteek meet, en wat die uitwerking van die onderskeie optimerings aantoon, word verskaf.

Texto completoIn this thesis, we propose a method for the visualisation of overlapping sets and of fuzzy graph clusterings based on Euler diagrams.Euler diagrams are probably the most intuitive and most used method to depict sets in which elements can be shared. Such a powerful visualisation metaphor could be an invaluable visualisation tool, but the automatic generation of Euler diagrams still presents many challenging problems. First, not all instances can be drawn using standard Euler diagrams. Second, most existing algorithms focus on diagrams of modest dimensions while real-world applications typically features much larger data. Third, the generation process must be reliable and reasonably fast.In this thesis, we describe an extended version of Euler diagrams that can be produced for every input instance. We then propose an automatic procedure for the generation of such diagrams that specifically target large input instances. Finally, we present a software implementation of this method and we describe some output examples generated on real-world data

Modelos UML são usados de várias formas na engenharia de software. Eles podem modelar desde requisitos até todo o software, e compreendem vários diagramas. O diagrama de classes, o mais popular dentre os diagramas da UML, faz uso de vários elementos UML e adornos, tais como abstração, interfaces, atributos derivados, conjuntos de generalização, composições e agregações. Atualmente, não há maneira fácil de encontrar este tipo de diagrama com base nestas características para a reutilização ou a aprendizagem por tarefas de exemplo. Por outro lado, Sistemas de Recomendação são ferramentas e técnicas que são capazes de descobrir os elementos mais adequados para um usuário, dentre muitos outros. Existem várias técnicas de recomendação, que usam informações dos elementos de várias maneiras, ao uso da opinião de outros usuários. Sistemas de recomendação já foram utilizadas com sucesso em vários problemas da engenharia de software, a exemplo da recomendação de partes de código para reuso (como métodos,por exemplo) e da identificação do desenvolvedor mais adequado para trabalhar em certas áreas do software. Este trabalho tem como objetivo propor e avaliar (i) uma representação baseada em conteúdo para diagramas de classe e as preferências do usuário, (ii) um novo algoritmo de recomendação baseado no conhecimento, (iii) a aplicação deste algoritmo e outros dois outros do estado da parte para a recomendação de diagramas de classe UML e (iv) uma avaliação destas abordagens contra uma sugestão aleatória. Para atingir este objetivo, foi realizado um estudo de caso com estudantes de ciência da computação e egressos. Depois de comparar os algoritmos, os nossos resultados mostram que, para o nosso conjunto de dados, todos eles são melhores do que uma recomendação aleatória.
UML models are used in several ways in the software engineering. They can model from requirements to the entire software, and comprise several diagrams. The Class diagram, the most popular among the UML diagrams, makes use of several UML elements and adornments, such as abstraction, interfaces, derived attributes, generalization sets, compositions and aggregations. Currently, there is no easy way to find this kind of diagram based on these features for reuse or learning by example’s tasks, for instance. On the other hand, Recommender Systems are powerful tools and techniques that are able to discover the most appropriate elements to an user among many others. There are several recommender techniques, from using the elements’ information in several ways, to using other users’ opinions. Recommender systems were already used successfully in several software engineering problems, as discovering pieces of code to recommend (as methods, for example) and finding the best developer to work in certain software problems. This work aims to propose and evaluate (i) a content-based Recommender System’s representation for class diagrams’ features and user’s preferences, (ii) a new knowledge-based recommender algorithm, (iii) the application this algorithm and two other state of the art content-based on esto the recommendation of UML class diagrams and (iv) an evaluation of these approaches against a random suggestion. To achieve this goal, we conducted a case study with computer science students and egresses. After comparing the algorithms, our results show that, for our dataset, all of them are better than a random recommendation.

Texto completoProtein crystallization is a key step in elucidating three-dimensional structure of proteins. This very sensitive process depends on many variables that are difficult to control precisely or simultaneously in the existing facilities. Instrumentation developments have concentrated on massive parallel experiments and sample volume reduction used by experiment. With this approach it is relatively easy to find initial crystallization conditions but their optimization to yield well diffracting crystals often proves to be more difficult.The method presented herein differs from the current paradigm, since we propose serial instead of parallel experiments based on the knowledge of phase diagrams. This project is based on a series of developments of instruments used to control and rationalize crystallisation using dialysis method, thus allowing phase diagrams exploration without consuming large quantity of protein sample.This results in a microfluidic device that allows crystallization of proteins by dialysis method, use of a continuous flow of crystallization agent and therefore continuous exchange of crystallization conditions as well as temperature control during experiment. It provides X-rays compatibility for in situ diffraction data collection of crystals grown in the microfluidic chip. This microfluidic system is based on the miniaturization of the crystallization bench which has been improved on electronics for automation, fluid transport to operate at a continuous flow, software development for the control of crystallization parameters, mechanics to improve both dialysis cell and thermoregulation, and finally by the integration of a UV system to perform in situ absorbance measurements that provide the future possibility to measure the solubility of proteins in a dialysis crystallization experiment.Finally both instrumental and methodological developments have been validated by the crystallization of several model proteins whose crystals diffracted succesfully X-rays. Furthermore understanding of the transport of species in solution by dialysis was investigated by combined experimental and theoretical approaches
Anzellini, Simone. "Phase diagram of iron under extreme conditions measured with time resolved methods". Thesis, Paris 6, 2014. http://www.theses.fr/2014PA066155/document.
Texto completoThis thesis concerns the study of the phase diagram of iron at extreme conditions of pressure and temperature. Iron is the main constituent of the terrestrial planetary cores. In particular, the Earth has a solid inner core and a liquid outer core which are mainly composed of iron. The accurate determination of the melting temperature of iron at the inner core boundary pressure, 330 GPa, would provide an important constraint on the temperature of the core, which is essential to understand how the dynamic Earth works. The phase diagram of iron has been investigated in laser-heated diamond anvil cell experiments up to 200 GPa using synchrotron-based fast X-ray Diffraction as a primary melting diagnostic. The obtained melting temperatures agree within the experimental uncertainties with the ones obtained from shock wave experiments and are higher than those reported by previous static experiments, where a different melting criterion was used. The apparatus, methods and metrology used in the static laser heated diamond anvil cell are discussed together with the issues encountered in static experiments at such extreme conditions. The possibility of using the X-ray diffraction signal of Re gasket for pressure calibration purpose for experiment in the multi-Mbar range is also discussed. For this purpose, Re equation of state has been measured up to 144 GPa. Finally, a preliminary test has been performed to check the possibility of using energy dispersive X-ray absorption spectroscopy as a technique complementary to fast X-ray diffraction in the investigation of the melting curve of iron

Resumo: O desempenho de jogadores de futebol de elite durante uma partida é diretamente influenciado por fatores físicos, psicológicos, técnicos, táticos e entre outros. Um suporte científico capaz de buscar e aplicar metodologias que quantifiquem esses fatores é uma fonte importante de informações para que técnicos e treinadores tenham melhores condições de efetuar uma boa preparação da sua equipe. Dentro dos estudos cinemáticos no esporte, a videogrametria tem se mostrado uma ferramenta acurada para a obtenção da posição dos jogadores em função do tempo. Dentro dos aspectos táticos de um jogo de futebol, a forma como uma equipe divide o campo em áreas de responsabilidade e como essa distribuição se dá ao longo do jogo pode ser descrita através de técnicas matemáticas. Nesse sentido, o objetivo deste estudo será apresentar uma forma de representação da área de responsabilidade de jogadores de futebol durante partidas oficiais, através do Diagrama de Voronoi. Para tal, foram coletadas as imagens de 4 jogos de futebol. Os processos de segmentação das imagens e de rastreamento dos jogadores para a obtenção dos dados 2D em função do tempo foram realizados através do software DVideo®. Para as análises, foi aplicado a metodologia do Diagrama de Voronoi nas coordenadas 2D de 33 jogadores de uma mesma equipe, a cada instante de tempo, em cada jogo. Dado um conjunto de pontos no plano (que nesse caso, representam as posições dos jogadores em função do tempo), o Diagrama de Voronoi divide o plano em regiões de acordo com as distâncias entre os pontos desse conjunto, chamados Polígonos de Voronoi. As áreas dos polígonos foram calculadas. Essa ferramenta permite, através de uma representação por mapas de superfície, obter um resumo dos locais do campo contidos nos Polígonos de Voronoi associados a cada jogador, durante todo o jogo. As áreas de responsabilidade foram maiores para goleiros, laterais e atacantes, quando comparados aos zagueiros e volantes e meias.Para caracterizar a região de responsabilidade dos jogadores, foi utilizado o contorno topográfico correspondente às áreas do campo contidas nos Polígonos dos jogadores por no mínimo 60% do jogo. Os resultados obtidos para os jogos estudados mostram que o contorno que caracteriza a área de responsabilidade para os jogadores é uma boa ferramenta qualitativa e quantitativa, que representa a forma como os jogadores dividem a área do campo entre si. A utilização do Diagrama de Voronoi se mostrou uma técnica eficiente na determinação das áreas de responsabilidade dos jogadores. Técnicos e treinadores podem dessa maneira obter informações adicionais importantes para a criação de melhores estratégias de posicionamento da sua equipe para uma melhor cobertura do espaço do campo de futebol
Abstract: The performance of football elite players is directly influenced by physical, psychological, technical and tactical aspects. A scientific support capable of seek and apply methodologies to quantifying these factors is an important source of information to coaches improve their conditions to well prepare their teams. About football tactical aspects, the manner a team share the pitch in responsibility areas and how this distribution behaviours during the match can be described through mathematical techniques. Thus, the aim of this study is to show players' responsibility area during official matches using Voronoi Diagram (VD). To do so, we collected images of 4 football matches. To extract 2D players' coordinates during the entire match, images segmentation, tracking and 2D reconstruction were performed in DVideo® software. In the analysis, VD method was applied to players' 2D coordinates to all 33 players of a same team, at each instant of time and in the 4 matches. Given a set of points on plan (representing players positions as function of time), VD share the plan in regions according to distances between all points of the set, called Voronoi polygons (VP). Voronoi areas were calculated a determined as players' responsibility areas. This tool permits obtaining a summary of pitchlocations inside Voronoi polygons of each player, during the entire match, using hitmaps. To characterize responsibility areas, the contours of hitmaps corresponding to pitch areas inside VP by, at least, 60% of the match were performed. The results showed contours as an effective tool to qualitatively and quantitatively represent responsibility areas in a match. Besides, mathematical properties related to known geometric structures, as convex polygons, facilitate calculating areas. They showed be higher to goalkeepers, external defenders and forwards when compared to central defenders, defensive and offensive midfielders

Resumo: A simulação de processos é um componente fundamental de uma grande variedade de atividades de Engenharia de Processos, tais como a Otimização Online, o controle em Tempo Real, a Identificação, etc. O cálculo de Equilíbrio de Fases é uma atividade fundamental em qualquer simulação de processos de separação. O elevado tempo computacional deste cálculo provocado pela sua natureza iterativa pode criar incompatibilidades entre a atividade de simulação e as aplicações em tempo real que ela integra. O objetivo deste trabalho foi desenvolver um método alternativo simples, mas suficientemente preciso, para realizar os cálculos de equilíbrio de fases na simulação de processos de separação de sistemas complexos. Entende-se por tal, sistemas que apresentam problemas de Equilíbrio Líquido-Líquido e de Equilíbrio Líquido-Líquido-Vapor, como é o caso dos que possuem um Azeótropo Heterogêneo. Pelas suas propriedades, as Redes Neurais Artificiais surgem naturalmente como candidatas alternativas para esta tarefa. Como objeto de aplicação foram escolhidos dois sistemas que apresentam um azeótropo heterogêneo, o sistema binário acetato de etila - água e o sistema ternário etanol - acetato de etila - água. Para gerar os dados usados no treinamento das redes foi implementado um método convencional de cálculo de equilíbrio de fases, adequado à complexidade dos sistemas escolhidos, o método de Pham & Doherty. Para a resolução do problema da estabilidade de fases, a primeira etapa do cálculo do equilíbrio de fases, foram testados dois tipos de redes neurais artificiais (RNAs), as Redes Neurais Artificiais Probabilísticas (RNAPs) e os Perceptrons. Com os perceptrons foram encontradas dificuldades para atingir a precisão desejada, sendo necessário recorrer a perceptrons com várias camadas escondidas. Já as RNAPs apresentaram uma excelente precisão, embora a sua simulação seja mais lenta. Perceptrons simples de uma só camada escondida foram usados com êxito na solução da segunda etapa do cálculo de equilíbrio de fases, o problema da divisão de fases. Combinando as redes desenvolvidas para cada uma das etapas foi criada uma ferramenta que permite resolver qualquer problema de equilíbrio de fases para os sistemas estudados. A precisão dos resultados fornecidos pelas redes neurais é comparável à dos apresentados pelos métodos tradicionais, mas os cálculos do equilíbrio de fases feitos usando redes neurais foram mais rápidos. Pode-se concluir que as redes neurais artificiais constituem uma alternativa válida aos métodos tradicionais do cálculo do equilíbrio de fases baseados em equações de estado para sistemas complexos como os avaliados
Abstract: Process simulation is a basic component of different Process Engineering activities such as On-line Optimization, Model Predictive Control, Identification, etc. The calculation of Phase Equilibrium appears as a fundamental task in any simulation of a separation process. However, the high computational time due to the iterative nature of this calculation makes it oft unsuitable for use with real time process analysis and synthesis strategies. The objective of this work is to develop a simple but accurate method to perform the phase equilibrium calculations required to the study of the behavior of complex systems. As such we mind those systems who present liquid-liquid and vapor-liquid-liquid phase equilibrium problems, such as systems with a heterogeneous azeotrope do. Given their inherent ability to learn and recognize non-linear and highly complex relationships, artificial neural networks (ANNs) appear to be well suited for such a task. Two chemical systems, the binary ethyl acetate ¿ water and the ternary ethanol ¿ ethyl acetate ¿ water were chosen; both systems present a miscibility gap and a heterogeneous azeotrope. The data sets used to train the ANNs were computed using the method of Pham & Doherty. Two kinds of neural networks were tried to solve the phase stability problem, namely the probabilistic neural networks (PNNs) and the perceptrons. In order to attain an acceptable precision perceptrons had to be trained with several hidden layers. Even though, PNNs got slightly better results than the perceptrons. Simple perceptrons were able to deliver the required precision when trained to predict the compositions of phases in equilibrium. Coupling the ANNs trained for phase stability with those trained for phase division a tool was obtained that can solve any phase equilibrium problem for the two chosen systems. Predictions made with the use of neural networks were faster than those made using the traditional methods, and delivered comparable precision

Texto completoThis research aims to analyse topologys state of the art. Nowadays topology is a key player in the dialogues that architecture has historically stablished with other areas of knowledge. This work points out and systematizes contemporary approximations with topology made by architects and developes their ideas by means of the concept of topologic processual diagram. This threefold concept (topology, process, diagram) is investigated in different areas such cognitive science, logic (mathematics and semiotics) and philosophy, in order to enrich the analyse of its actuation in the field of topology. In this analysis, the topologic processual diagram is described as an operative-representational medium of spatial structural relations (the objects topology), with three variables: thought, space and time. Finally, this concept is investigated within the realm of the project and representation in architecture, building up a critical dialogue with diagrams, its use and reference, as performed by paradigmatic contemporary architects - Bernard Tschumi, Peter Eisenman, Greg Lynn, Rem Koolhaas, MVRDV, Ben van Berkel, Lars Spuybroek and others

Texto completoThis thesis is devoted to the making of inert anode materials, used for aluminium electrolysis. On the basis of knowledge obtained from the cermet copper- nickel ferrite, a strategy of research was carried out in order to determine alternative chemical systems. The reading of phase diagrams is a tool of prediction for hypothetical promising compositions. Physical models of spinel conductivity and sintering, integrated into the results of thermodynamic calculation, are used to determine theoretical best zones of cermets'development, in the system Al-Co-Cr-Fe-Ni-Zn-O (FACT database). Manganese, comparable with iron and cobalt concerning the electronic structure, is not included in FACT database and Fe-Mn-Ni-0 had to be evaluated through experiments and theoretically in order to include it in our thought and to show its interest as an alloying element. Practical application was validated in the case of Cu-Al-Fe-Ni-0 and Cu-Fe-Mn-Ni-0 materials. Addition of aluminium reduces the solubility in cryolite bath, and manganese can be used as a doping element in order to enhance sintering. The potential interest of the other elements (Co,Cr and Zn) has been surveyed through a logical analysis developed during the thesis

Texto completoIn this thesis, a 3D approach to visualize software metrics is presented. Software metrics are attributes of a piece of software or its specification. They generally contain a set of multivariate time-series data and can be displayed, for example, as a Kiviat diagram consisting of axes and polylines. The aim of this work is to design a Win32 application that can load multivariate time-series data from a file and visualize it as an interactive 3D Kiviat diagram.
There has been an approach that can display software metrics by using 2D Kiviat diagrams, but there are still some drawbacks on it. Since a better visualization of software metrics can help the developer to control the quality of software products more easily, this thesis improved the existing approach by extending 2D Kiviat diagram to 3D Kiviat diagram.
