Esta dissertação apresenta o desenvolvimento e otimização de uma metodologia baseada em código comercial para previsão de ruído em um eslate, além do estudo da dependência do ruído ao variar a camada limite do aerofólio. Com a contínua redução do ruído produzido por motores em aeronaves e as sucessivas restrições nos níveis de certificação, o ruído produzido por dispositivos aerodinâmicos tem ganhado importância no projeto de uma aeronave. Durante o pouso, o ruído gerado pelos dispositivos hiper-sustentadores é classificado dentre os mais relevantes, sendo o eslate um de seus componentes. Este trabalho busca criar e otimizar uma metodologia baseada no código PowerFLOW, assim como estudar a influência das camadas limite do aerofólio na geração de ruído. Tal código é baseado na formulação de Lattice- Boltzmann. As fontes acústicas simuladas são propagadas utilizando uma analogia acústica de Ffowcs-Williams e Hawkings e, então, analisadas utilizando métodos estatísticos de análise de sinais. Estudos de validação e verificação do código baseados em soluções analíticas são apresentados, tais como uma camada de mistura periódica no espaço e a solução dos vórtices de Taylor-Green. A seguir, o aerofólio 30P30N é utilizado em todo o estudo relacionado a eslates, analisando primeiramente a independência da solução em relação ao nível de refinamento da malha e do tamanho do domínio empregados. Baseado nas recomendações de tal estudo, o resultado é comparado com simulações disponíveis na literatura. Com uma maior confiança na metodologia, o trabalho então apresenta estudos variando a camada limite em regiões do eslate, assim como removendo-a completamente em certas regiões do aerofólio ao empregar condições de contorno de livre-escorregamento. O trabalho mostra que a influência das camadas limite do aerofólio é desprezível em relação ao erro do método. Isso é causado pela aparente independência do ruído do eslate em relação ao escoamento perto de sua cúspide. Tal independência permite que a malha computacional seja otimizada, reduzindo o custo da simulação em até 60%. / This dissertation presents the development and optimization of a methodology based on a commercial software to predict slat noise, also studying noise dependency when varying airfoil boundary layers. Due to continuous reduction on aircraft engine noise and successive restrictions on noise certification levels, airframe noise has been gaining importance on aircraft design. During landing, high-lift noise is ranked as one of the most relevant ones, being slat noise one of its components. This work focuses on creating and optimizing a noise prediction methodology based on the software PowerFLOW, and also on studying the influence of airfoil boundary layers on noise generation. Such software is based on Lattice-Boltzmann formulation. The simulated sound sources are propagated using Ffowcs-Williams and Hawkings acoustic analogy and then analyzed by signal analysis methods. Code validation and verification studies based on analytical solutions are presented, such as the spacially-periodic mixing layer and the Taylor-Green vortices solutions. Following, the 30P30N airfoil is employed through the rest of this work, firstly studying the solution independency related to mesh refinement level and computational domain size. Based on recommendations from this study, the results are compared to simulations from the literature. With higher confidence levels on this methodology, the work then presents studies varying the slat boundary layer and also removing it completely by employing free-slip boundary conditions on certain airfoil regions. This work presents that the airfoil boundary layer influence is neglectable when compared to the method error. This is caused by the apparent slat noise independency related to the flowfield near the slat cusp. Such independency allows the computational mesh to be optimized, reducing the simulation cost by up to 60%.

A exemplo de qualquer outra atividade que se destine a produzir um produto, a engenharia de software necessariamente passa por um fase inicial, onde necessário definir o que será produzido. A análise de requisitos é esta fase inicial, e o produto dela resultante é a especificação do sistema a ser construído. As duas atividades básicas durante a analise de requisitos são a eliciação (busca ou descoberta das características do sistema) e a modelagem. Uma especificação completa e consistente é condição indispensável para o adequado desenvolvimento de um sistema. Muitos tem sido, entretanto, os problemas enfrentados pelos analistas na execução desta tarefa. A variedade e complexidade dos requisitos, as limitações humanas e a dificuldade de comunicação entre usuários e analistas são as principais causas destas dificuldades. Ao considerarmos o ciclo de vida de um sistema de informação, verificamos que a atividade principal dos profissionais em computação é a transformação de uma determinada porção do ambiente do usuário, em um conjunto de modelos. Inicialmente, através de um modelo descritivo representamos a realidade. A partir dele derivamos um modelo das necessidades (especificação dos requisitos), transformando-o a seguir num modelo conceitual. Finalizando o ciclo de transformações, derivamos o modelo programado (software), que ira se constituir no sistema automatizado requerido. Apesar da reconhecida importância da analise dos requisitos e da conseqüente representação destes requisitos em modelos, muito pouco se havia inovado nesta área ate o final dos anos 80. Com a evolução do conceito de reutilização de software para reutilização de especificações ou reutilização de modelos de requisitos, finalmente surge não apenas um novo método, mas um novo paradigma: a reutilização sistemática (sempre que possível) de modelos integrantes de especificações de sistemas semelhantes ao que se pretende desenvolver. Muito se tem dito sobre esta nova forma de modelagem e um grande número de pesquisadores tem se dedicado a tornar mais simples e eficientes várias etapas do novo processo. Entretanto, para que a reutilização de modelos assuma seu papel como uma metodologia de use geral e de plena aceitação, resta comprovar se, de fato, ele produz software de melhor quantidade e confiabilidade, de forma mais produtiva. A pesquisa descrita neste trabalho tem por objetivo investigar um dos aspectos envolvido nesta comprovação. A experimentação viabilizou a comparação entre modelos de problemas construídos com reutilização, a partir dos modelos de problemas similares previamente construídos e postos a disposição dos analistas, e os modelos dos mesmos problemas elaborados sem nenhuma reutilização. A comparação entre os dois conjuntos de modelos permitiu concluir, nas condições propostas na pesquisa, serem os modelos construídos com reutilização mais completos e corretos do que os que foram construídos sem reutilização. A apropriação dos tempos gastos pelos analistas durante as diversas etapas da modelagem, permitiu considerações sobre o esforço necessário em cada um dos dois tipos de modelagem. 0 protocolo experimental e a estratégia definida para a pesquisa possibilitaram também que medidas pudessem ser realizadas com duas series de modelos, onde a principal diferença era o grau de similaridade entre os modelos do problema reutilizado e os modelos do problema alvo. A variação da qualidade e completude dos dois conjuntos de modelos, bem como do esforço necessário para produzi-los, evidenciou uma questão fundamental do processo: a reutilização só terá efeitos realmente produtivos se realizada apenas com aplicações integrantes de domínios específicos e bem definidos, compartilhando, em alto grau, dados e procedimentos. De acordo com as diretrizes da pesquisa, o processo de reutilização de modelos de requisitos foi investigado em duas metodologias de desenvolvimento: na metodologia estruturada a modelagem foi realizada com Diagramas de Fluxo de Dados (DFD's) e na metodologia orientada a objeto com Diagramas de Objetos. A pesquisa contou com a participação de 114 alunos/analistas, tendo sido construídos 175 conjuntos de modelos com diagramas de fluxo de dados e 23 modelos com diagramas de objeto. Sobre estas amostras foram realizadas as analises estatísticas pertinentes, buscando-se responder a um considerável número de questões existentes sobre o assunto. Os resultados finais mostram a existência de uma série de benefícios na análise de requisitos com modelagem baseada na reutilização de modelos análogos. Mas, a pesquisa em seu todo mostra, também, as restrições e cuidados necessários para que estes benefícios de fato ocorram. / System Engineering, as well as any other product oriented activity, starts by a clear definition of the product to be obtained. This initial activity is called Requirement Analysis and the resulting product consists of a system specification. The Requirement Analysis is divided in two separated phases: elicitation and modeling. An appropriate system development definition relies in a complete, and consistent system specification phase. However, many problems have been faced by system analysts in the performance of such task, as a result of requirements complexity, and diversity, human limitations, and communication gap between users and developers. If we think of a system life cycle, we'll find out that the main activity performed by software engineers consists in the generation of models corresponding to specific parts of the users environment. This modeling activity starts by a descriptive model of the portion of reality from which the requirement model is derived, resulting in the system conceptual model. The last phase of this evolving modeling activity is the software required for the system implementation. In spite of the importance of requirement analysis and modeling, very little research effort was put in these activities and none significant improvement in available methodologies were presented until the late 80s. Nevertheless, when the concepts applied in software reuse were also applied to system specification and requirements modeling, then a new paradigm was introduced, consisting in the specification of new systems based on systematic reuse of similar available system models. Research effort have been put in this new modeling technique in the aim of make it usable and reliable. However, only after this methodology is proved to produce better and reliable software in a more productive way, it would be world wide accepted by the scientific and technical community. The present work provides a critical analysis about the use of such requirement modeling technique. Experimental modeling techniques based on the reuse of similar existing models are analyzed. Systems models were developed by system analyst with similar skills, with and without reusing previously existing models. The resulting models were compared in terms of correction, consumed time in each modeling phase, effort, etc. An experimental protocol and a special strategy were defined in order to compare and to measure results obtained from the use of two different groups of models. The main difference between the two selected groups were the similarity level between the model available for reuse and the model to be developed. The diversity of resulting models in terms of quality and completeness, as well in the modeling effort, was a corroboration to the hypothesis that reuse effectiveness is related to similarity between domains, data and procedures of pre-existing models and applications being developed. In this work, the reuse of requirements models is investigated in two different methodologies: in the first one, the modeling process is based on the use of Data Flow Diagrams, as in the structured methodology; in the second methodology, based on Object Orientation, Object Diagrams are used for modeling purposes. The research was achieved with the cooperation of 114 students/analysts, resulting in 175 series of Data Flow Diagrams and 23 series of Object Diagrams. Proper statistical analysis were conducted with these samples, in order to clarify questions about requirements reuse. According to the final results, modeling techniques based on the reuse of analogous models provide an improvement in requirement analysis, without disregarding restrictions resulting from differences in domain, data and procedures.

Activity-based analogy follows the Teaching-With-Analogies model developed by Glynn and modified by Harrison and Treagust. The analogous for the study of heat and temperature by means of the modified Teaching- With-Analogies model is based on an experiment of Valadares. Activities with scientific texts make use of articles of Scientific American Brasil and Ciência Hoje at two different pedagogical moments. The implementation of activities take place with participants of the 2nd grade of secondary school of Escola Estadual Don Antônio Reis, Faxinal do Soturno, RS, between October and November 2009. Through the transcription of the videorecordings, and guides of the student, we discuss the impact and effectiveness of activities. / Esta dissertação apresenta o planejamento e a implementação de uma unidade didática que contempla atividades baseadas em analogia e texto de divulgação científica para o ensino de calor e temperatura em nível médio, segundo o modelo de momentos pedagógicos como proposto por Delizoikov e Angotti, em uma perspectiva de educação em CTS.

随着社会的发展，尤其是互联网的发展，很多语言每年都涌现出了不少新词汇。词语是每个语言最基本也是最重要的组成部分，因此分析这些新词汇的结构特点以及构词法是很有意义的。这篇文章分析了2014年出现在中文里的新词汇和它们的构词方式，论文的目的是为了更好地了解中文词汇的发展和特点。本文以《2014汉语新词语》中公布的2014年出现的新词汇作为语料进行分析，发现了以下两个主要特点：第一，合成法，派生法，缩略法是2014年产生的新词汇的主要构词方式；第二， 百分之七十二的新词汇是多音节词（包含三个或者三个以上音节），而百分之八十的是名词。这些特点说明中文词汇现阶段的特点和发展趋势，跟传统的中文词汇有不同之处。 / The aim of this thesis was to investigate how new Chinese words are formed and to examine the linguistic patterns among them. This thesis focused on the analysis of Chinese words formed in 2014. The quantitative data for the analysis included a collection of 423 new Chinese words from the book 2014 汉语新词语 (hànyǔxīn cíyǔ) by Hou and Zhou. Parts of speech and number of syllables in the new words were investigated, although the focus was on word-formation processes. A discussion of derivation, blending, abbreviation, analogy, borrowing, change of meaning, compounding and inventions is also included. The share of each word-formation process used for each of the new words was presented statistically in order to reveal the significance of each word-formation process. The analysis showed that compounding, derivation and abbreviation were the major word-formation processes in 2014. The study also suggests that words formed by derivation and analogy were much more frequent in 2014, in comparison to previous studies. Furthermore, the ways words are formed in Chinese are changing and evolving, as some word-formation processes are becoming more frequently used in the formation of new words.

Le présent travail entend développer une théorie permettant de décrire, d’expliquer et de réguler les désaccords moraux. Il privilégie une approche empirique du désaccord moral, mobilisant en priorité les données fournies par la psychologie sociale et la psychologie morale.La morphologie du désaccord moral (partie 1) indique que ce dernier puise sa source dans un imaginaire polémique, structuré par trois éléments : l’analogie, la métaphore, et le symbole. L’hybridation de ces éléments génère des réseaux symboliques, organisant la relation entre les protagonistes du désaccord.La généalogie du désaccord moral (partie 2) vise à déterminer empiriquement les origines de ces réseaux symboliques. Nous examinerons les processus psychologiques, anthropologiques, et socio-historiques sous-jacents au désaccord. Le rôle central de la famille –en tant que matrice, modèle, et objet du désaccord– sera ici souligné.La polémologie du désaccord moral (partie 3) s’emploie à réorganiser les réseaux symboliques dans une approche pragmatique et normative. Nous détaillerons les procédures visant à réguler les désaccords moraux et à transformer l’imaginaire polémique en imaginaire consensuel.S’ouvre alors la perspective d’une valorisation du désaccord, préalable indispensable à la réhumanisation de l’espace moral.Mots-clés : désaccord moral, philosophie morale, psychologie sociale, psychologie morale, imaginaire, analogie, métaphore, symbole, famille. / The aim of this study is to develop a theory in order to describe, explain, and regulate moral disagreements. Ours is an empirical approach to moral disagreement, based mainly on empirical data provided by social and moral psychology.The morphology of moral disagreement (part 1) reveals that it is drawn from polemical imagination, which consists of three key elements: analogy, metaphor, and symbol. Such hybridization gives birth to symbolic networks, organizing the relationship between the moral opponents.The genealogy of moral disagreement (part 2) aims to determine the sources of these symbolic networks. We will analyse the psychological, anthropological, and socio-historical processes underlying the moral disagreements. The key role of family – as matrix, model and object of disagreement – will be emphasized.The polemology of moral disagreement (part 3) attempts to reorganize the symbolic networks through a pragmatic and normative approach. We will analyse the procedures in view of a regulation including the transformation of polemical imagination into consensual imagination.Thus, moral disagreement must be reasserted, before any attempt to rehumanising the moral field.Key-words: moral disagreement, moral philosophy, social psychology, moral psychology, imagination, analogy, metaphor, symbol, family

Integration of knowledge has become a contentious issue in an age where increasing specialisation creates boundaries and division. Yet, there is an identifiable need for integration across social, ecological and economic understandings if we are to address ever more threatening crises and alarming potential scenarios. This paper relates to the work of K. William Kapp and in so doing raises questions about how integration might be achieved. A core idea that arises is the role of common denominator concepts.

Cette thèse propose une étude globale des bestiaires rabelaisiens à partir de l’exploration de ses sources antiques et médiévales. La focale critique se concentre d’abord sur les torsions qu’impose Rabelais aux genres littéraires rattachés à des figures animales prototypiques : l’inversion des paradigmes épiques du cheval et du porc ; le brouillage et la démultiplication des bêtes charivariques et farcesques ; la mise en crise des animaux exemplaires de la fable. Elle s’ouvre ensuite aux jeux du célèbre humaniste avec les figures animales des écrits savants et sérieux : encyclopédies, littérature gnomique, livres de cuisine. Finalement, le point de vue se renverse pour examiner les effets esthétiques et sensoriels de ces bestiaires sur le lecteur et l’auditeur, et en dégager une certaine esthétique grotesque. Cette enquête débouche sur la redéfinition de l’humanisme rabelaisien, qui se révèle dans l’épreuve et à l’épreuve d’une profusion d’images animales. / This dissertation analyses François Rabelais’ bestiaries through the exploration of its antique and medieval sources. The first part of this thesis focuses on the way Rabelais distorts certain literary genres containing prototypical animal figures by reversing the epic paradigms associated with horses and boars, multiplying and merging farces and charivaris’ animals, and undermining the exemplary animals portrayed in the fables. The next part uncovers how the famous humanist plays with animal figures drawn from scholarly and serious writings such as encyclopedias, gnomic literature, and recipe books. The third part overturns this perspective to examine the aesthetical and sensory impact of these bestiaries on the reader and listener as well as the grotesque aesthetic they seem to thrive from. Overall, this investigation leads to a redefinition of the Rabelaisian humanism, which reveals itself through an abundance of animal images.

Cette thèse recueille un grand nombre de recherches effectuées entre les années 1960-1990 en Europe et en Amérique dans le domaine du symbolisme phonétique consistant « en l’attribution d’une signification à un phonème ou un trait distinctif » (Monneret, 2003 : 98). Un enjeu pertinent est représenté par l’instauration de l’état des lieux des recherches phono-symboliques en Union Soviétique. L’approche comparativo-descriptive est accompagnée de l’application de la typologie relative au symbolisme phonétique née lors de la période mentionnée (le symbolisme subjectif versus le symbolisme objectif). Le présent travail scientifique relève les éventuelles causes du blocage des recherches avant 1960 ainsi que celles de l’essor des analyses pendant la période 1960-1990, en se focalisant sur la problématique théorique et la praxis accumulée autour des manifestations phono-symboliques. N’étant plus considéré comme un phénomène marginal, le symbolisme phonétique présenté comme le fait qui prend ses sources du concept de l’iconicité linguistique traitant des relations motivées entre la forme et le contenu et dont l’intérêt croissant se manifestera dans les années quatre-vingt, peut être analysé aujourd’hui à l’aide du concept d’analogie considérée dans les recherches récentes de Monneret (2014). / This thesis collects a relevant number of researches made between years 1960-1990 in Europe and in America in the field of the phonetic symbolism consisting “of the attribution of the meaning in a phoneme or a distinctive feature” (Monneret, 2003: 98; our translation). The important stake is represented by the institution of the current situation of the phono-symbolic researches in Soviet Union. The comparativo-descriptive approach is accompanied with the application of the typology relative to the phonetic symbolism been born during period mentioned (the subjective symbolism versus the objective symbolism). The present scientific work raises the possible causes of the blockage of the researches before 1960 as well as those of the development of analyses during the period 1960-1990, by focusing on the theoretical problem and the praxis accumulated around the phono-symbolic manifestations. No more considered as a marginal phenomenon, the phonetic symbolism presented as the fact that rises in the concept of the linguistic iconicity handling relations motivated between the form and the contents the increasing interest of which will show itself in the eighties, can be analyzed by means of the concept of analogy today considered in the recent researches (Monneret, 2014) as the emergent cognitive phenomenon involving similarity.

La circulation des flux de matières et d’énergie reflète aussi bien le fonctionnement de la biosphère que celui des sociétés humaines. L’écologie industrielle, dans son approche territoriale, interpelle ces interactions socioécologiques au sein d’un espace géographique et participe ainsi à la définition et à la structuration de l’espace en territoire. Par une approche expérimentale déclinée sur les espaces portuaires, nous cherchons à rendre manifeste, pour la valider et mieux l’appréhender, cette dynamique de configuration du territoire en écologie industrielle. Le territoire constitue une matrice complexe, composée de représentations et de pratiques, manifestées dans le discours des acteurs. A partir de l’étude de 21 cas portuaires d’écologie industrielle à l’échelle internationale, 9 modèles territoriaux ont été proposés pour l’observer et la décrypter. Déclinés dans l’espace portuaire de Marseille-Fos, ces modèles permettent la production et l’interprétation des discours des acteurs de la démarche d’écologie industrielle en vue d’identifier les modalités de construction territoriale à l’œuvre et de construire une configuration du territoire à l’interface des représentations et pratiques des acteurs. Cette expérimentation met en évidence un phénomène d’imbrication territoriale de l’écologie industrielle et la participation de celle-ci à une dynamique territorialité-territorialisation structurante de la construction territoriale. Elle propose ainsi une définition socioécologique du territoire, distinguant des biotopes et des niches occupés par des acteurs, dont les interactions appellent à un renouvellement de la gouvernance portuaire de l’écologie industrielle. / The circulation of material and energy flows reflects the functioning of both biosphere and human societies. Industrial ecology, in its territorial approach, questions these socioecological interactions within a geographical area. It contributes to the definition and structuration of land into territory. Through an experimental approach led upon port areas, the aim is to reveal this dynamic of territorial configuration in industrial ecology. Territory constitutes a complex matrix of representations and practices, uncovered in actors’ speeches. From the analysis of 21 industrial ecology port case studies at an international scale, 9 territorial patterns are defined in order to observe and interprete this dynamic. Implemented in Marseille-Fos port area, these patterns allow the production and the interpretation of actors’ speeches in order to identify the territorial construction modes and to build a common territorial configuration, at the interface of actors’ representations and practices. This experimentation highlights a territorial embeddedness phenomenon for industrial ecology. It reveales industrial ecology’s contribution to a “territoriality-territorialisation” dynamic, leading to territorial configuration. It thus proposes a socioecological definition of territory, identifying biotopes and niches occupied by different actors. The overlapping of these biotopes and niches questions the evolution of port governance for the implementation of industrial ecology.
