La transformation de modèles consiste à transformer un modèle source en un modèle cible conformément à des méta-modèles source et cible. Nous distinguons deux types de transformations. La première est exogène où les méta-modèles source et cible représentent des formalismes différents et où tous les éléments du modèle source sont transformés. Quand elle concerne un même formalisme, la transformation est endogène. Ce type de transformation nécessite généralement deux étapes : l’identification des éléments du modèle source à transformer, puis la transformation de ces éléments. Dans le cadre de cette thèse, nous proposons trois principales contributions liées à ces problèmes de transformation. La première contribution est l’automatisation des transformations des modèles. Nous proposons de considérer le problème de transformation comme un problème d'optimisation combinatoire où un modèle cible peut être automatiquement généré à partir d'un nombre réduit d'exemples de transformations. Cette première contribution peut être appliquée aux transformations exogènes ou endogènes (après la détection des éléments à transformer). La deuxième contribution est liée à la transformation endogène où les éléments à transformer du modèle source doivent être détectés. Nous proposons une approche pour la détection des défauts de conception comme étape préalable au refactoring. Cette approche est inspirée du principe de la détection des virus par le système immunitaire humain, appelée sélection négative. L’idée consiste à utiliser de bonnes pratiques d’implémentation pour détecter les parties du code à risque. La troisième contribution vise à tester un mécanisme de transformation en utilisant une fonction oracle pour détecter les erreurs. Nous avons adapté le mécanisme de sélection négative qui consiste à considérer comme une erreur toute déviation entre les traces de transformation à évaluer et une base d’exemples contenant des traces de transformation de bonne qualité. La fonction oracle calcule cette dissimilarité et les erreurs sont ordonnées selon ce score. Les différentes contributions ont été évaluées sur d’importants projets et les résultats obtenus montrent leurs efficacités. / Model transformations take as input a source model and generate as output a target model. The source and target models conform to given meta-models. We distinguish between two transformation categories. Exogenous transformations are transformations between models expressed using different languages, and the whole source model is transformed. Endogenous transformations are transformations between models expressed in the same language. For endogenous transformations, two steps are needed: identifying the source model elements to transform and then applying the transformation on them. In this thesis, we propose three principal contributions. The first contribution aims to automate model transformations. The process is seen as an optimization problem where different transformation possibilities are evaluated and, for each possibility, a quality is associated depending on its conformity with a reference set of examples. This first contribution can be applied to exogenous as well as endogenous transformation (after determining the source model elements to transform). The second contribution is related precisely to the detection of elements concerned with endogenous transformations. In this context, we present a new technique for design defect detection. The detection is based on the notion that the more a code deviates from good practice, the more likely it is bad. Taking inspiration from artificial immune systems, we generate a set of detectors that characterize the ways in which a code can diverge from good practices. We then use these detectors to determine how far the code in the assessed systems deviates from normality. The third contribution concerns transformation mechanism testing. The proposed oracle function compares target test cases with a base of examples containing good quality transformation traces, and assigns a risk level based on the dissimilarity between the two. The traces help the tester understand the origin of an error. The three contributions are evaluated with real software projects and the obtained results confirm their efficiencies.

This final thesis deals with innovations in the management of informal education. The main objective is to highlight the importance of innovations in informal and leisure education, and bring inspiration to the managers of informal and leisure education in the form of examples of good practice. In the theoretical part informal and interest education is incorporated into the overall educational system of the Czech Republic and its development is illustrated on the laws and decrees from 1948 to present. The research in the form of structured interview with respondents revealed their view on innovations in leisure education and showed their experience with the introduction of innovations in their own organizations. The process and the conclusions of structured interviews clearly highlighted the need for innovation in informal and leisure education for the competitiveness of informal education organizations. The executives of school facilities for leisure education as well as organizations of informal education can hereby find inspiration for each specific innovation in the examples of good practice.

L’objet principal de cette thèse est de proposer des méthodes pour la synthèse de formes qui soient contrôlables et permettent d’imprimer les résultats obtenus. Les imprimantes 3D étant désormais plus faciles d’accès que jamais, les logiciels de modélisation doivent maintenant prendre en compte les contraintes de fabrication imposées par les technologies de fabrication additives. En conséquence, des algorithmes efficaces doivent être développés afin de modéliser les formes complexes qui peuvent être créées par impression 3D. Nous développons des algorithmes pour la synthèse de formes par l’exemple qui prennent en compte le comportement mécanique des structures devant être fabriquées. Toutes les contributions de cette thèse s’intéressent au problème de génération de formes complexes sous contraintes géométriques et objectifs structurels. Dans un premier temps, nous nous intéressons à la gestion des contraintes de fabrication, et proposons une méthode pour synthétiser des structures de support efficaces qui sont bien adaptées aux imprimantes à filament. Dans un deuxième temps, nous prenons en compte le contrôle de l’apparence, et développons de nouvelles méthodes pour la synthèse par l’exemple qui mélangent astucieusement des critères sur visuels, et des contraintes sur le comportement mécanique des objets. Pour finir, nous présentons une méthode passant bien à l’échelle, afin de contrôler les propriétés élastiques des structures imprimées. Nous nous inspirons des méthodes de synthèse de texture procédurales, et proposons un algorithme efficace pour synthétiser des microstructures imprimables et contrôler leurs propriétés élastiques / The main goal of this thesis is to propose methods to synthesize shapes in a controllable manner, with the purpose of being fabricated. As 3D printers grow more accessible than ever, modeling software must now take into account fabrication constraints posed by additive manufacturing technologies. Consequently, efficient algorithms need to be devised to model the complex shapes that can be created through 3D printing. We develop algorithms for by-example shape synthesis that consider the physical behavior of the structure to fabricate. All the contributions of this thesis focus on the problem of generating complex shapes that follow geometric constraints and structural objectives. In a first time, we focus on dealing with fabrication constraints, and propose a method for synthesizing efficient support structures that are well-suited for filament printers. In a second time, we take into account appearance control, and develop new by-example synthesis methods that mixes in a meaningful manner criteria on the appearance of the synthesized shapes, and constraints on their mechanical behavior. Finally, we present a highly scalable method to control the elastic properties of printed structures. We draw inspiration from procedural texture synthesis methods, and propose an efficient algorithm to synthesize printable microstructures with controlled elastic properties

Cette thèse prend pour cadre la synthèse par l'exemple et l'édition de contenu graphique en infographie et propose une réflexion sur les possibles sources d'information utiles à ces fins. Contrairement aux techniques "procédurales", l'approche par l'exemple se distingue par sa grande simplicité d'utilisation : reviennent en effet à l'algorithme de synthèse l'identification, analyse et reproduction des éléments caractéristiques des exemples fournis en entrée par l'utilisateur. Ce mode de création de même que les techniques approfondies d'édition ont grandement contribué à la facilitation de la production à grande échelle de contenus graphiques convaincants et ainsi participé à l'adoption par la communauté des artistes des outils proposés par le support numérique. Mais pour être ainsi exploitées, celles-ci doivent également être hautement contrôlables tout en évitant l'écueil de n'être que le simple prolongement de la main de l'artiste. Nous explorons ici cette thématique dans le cadre de la création de rendus dits expressifs et étudions les interactions (collaboratives ou concurrentielles) entre les différentes sources d'information au cœur de ce processus. Ces dernières sont à notre sens au nombre de trois : l'analyse automatique des données d'entrée avant rendu ou traitement ; l'utilisation de modèles a priori en vue de leur compréhension ; et enfin le contrôle explicite par l'utilisateur. En les combinant au plus juste, nous proposons des techniques nouvelles dans divers domaines de la synthèse en rendu expressif. Au delà du réalisme photographique, le rendu expressif se caractérise par sa poursuite de critères plus difficilement quantifiables tels la facilité de compréhension ou le caractère artistique de ses résultats. La subjectivité de tels objectifs nous force donc ici plus qu'ailleurs à estimer avec soin les sources d'information à privilégier, le niveau d'implication à accorder à l'utilisateur (sans que ce choix ne s'opère au détriment de la qualité théorique de la méthode), ainsi que le possible recours à des modèles d'analyse (sans en compromettre la généralité). Trois principales instances de synthèse sont ici détaillés : la génération de textures, la désaturation d'images, et la représentation de maillages par le dessin au trait. La grande variété des données d'entrée (textures matricielles ou vectorielles, images complexes, géométries 3d), des modalités de synthèse (imitation, conversion, représentation alternative) et d'objectifs (reproduction de la signature visuelle d'une texture, restitution crédible de contrastes chromatiques, génération de dessins conformes au style de l'utilisateur) permettent l'examen de divers équilibres entre ces sources d'information et l'exploration de degrés plus ou moins élevés d'interaction avec l'utilisateur. / This thesis focuses on example-based synthesis and editing in Computer Graphics and reflects on the possible sources of information necessary for such goals. Unlike "procedural" techniques, synthesis by example stands out thanks to its extreme ease-of-use : indeed, tasks such as identification, analysis and reproduction of the distinguishing features of the user-provided examples are left to the method itself. Such approaches, along with today's intricate editing methods have greatly favored the production of compelling graphical content at a wide scale, and henceforth facilitated the adoption of computer-assisted tools by artists. But in order to meet with success, they also have to be highly controllable without being a mere extension of the artist's hand. We explore here such concerns in the context of expressive rendering and study the interactions, may they be collaborative or competitive, between the different sources of information at the core of such processes. In our opinion, there are three main sources of information: the automatic analysis of the inputs before processing; the use of prior knowledge through predetermined models; and users' explicit intervention. Through a clever combination of these sources, we propose new expressive synthesis techniques which satisfy the aforementioned usability. More than photographic realism, expressive rendering strives for the fulfillment of less easily quantifiable goals such as the intelligibility or the aesthetic value of its results. The subjectivity behind the assessment of such criteria thus forces us to attach much importance to the careful choice of the source of information to favor; the required amount of user intervention (without being detrimental to the method's theoretical value); and the possible resort to prior models (without endangering its generality). Three main synthesis instances are studied in this document: texture generation, image de-colorization, and artistic line rendering. The great disparity of inputs (raster and vector textures, complex images, 3d meshes), terms of synthesis (imitation, conversion, depiction) and objectives (preservation of a texture's visual signature, plausible restitution of chromatic contrasts, creation of drawings in accordance with users' styles) gives rise to distinct balances between those sources of information and requires the consideration of various modes of user interaction.

Os artigos científicos são o principal veículo de comunicação para divulgação dos resultados obtidos por milhares de pesquisadores ao redor do mundo. Entretanto, escrever os artigos científicos em publicações de alto impacto é uma tarefa complexa para autores que têm o inglês como segunda língua. Por meio da aprendizagem baseada em exemplos e em experiência, as habilidades de leitura, interpretação e redação de textos científicos podem ser desenvolvidas por intermédio da prática, facilitada por meio de exemplos de trechos de texto reutilizáveis. Para auxiliar na redação de artigos, várias ferramentas computacionais foram desenvolvidas para dar suporte nas várias etapas de concepção do artigo. As ferramentas existentes, que aplicam este tipo de suporte, são todas voltadas para outros temas de pesquisa, incompatíveis com os temas da Engenharia de Produção, que por sua vez possui maneiras particulares de redigir e estruturar o texto. O objetivo da pesquisa desenvolvida consistiu em adaptar e avaliar um instrumento de auxílio à escrita em inglês dirigido a pesquisadores da Engenharia de Produção, fundamentada na aprendizagem baseada em exemplos e em experiências. Para tal fim, foram adaptadas duas ferramentas existentes para auxiliar nas tarefas de leitura, anotação e redação de artigos científicos, avaliadas por meio de dois experimentos com dez alunos de pós-graduação em Engenharia de Produção em universidade pública, nas quais o resultado foi aferido por intermédio de um questionário, buscando identificar os efeitos da utilização sobre o aprendizado e o tempo demandado. O instrumento adaptado oferece, além de exemplos extraídos de artigos publicados, uma estrutura mais coerente com os artigos relacionados à Engenharia de Produção. Os resultados apontam para 90% de aceitação do novo instrumento, em que os alunos relataram um efeito positivo sobre suas habilidades de escrita de artigos, além de uma economia de 11% no tempo dedicado à escrita. Assim sendo, o instrumento tem potencial de auxílio à escrita e sua aplicação traz benefícios reais aos usuários, passíveis de serem adaptadas para qualquer outra área de pesquisa. / Scientific articles are the main communication means of disseminating results obtained by researchers around the world. However, writing scientific articles to highimpact journals is a complex task to authors for whom English is a second language. By means of example- and experience-based learning, reading, interpretation, and writing skills as regards the production of scientific texts can be developed through practice, facilitated by the use of reusable text snippets. Several computational tools have been developed to support the various phases of scientific writing in English. Existing tools that cater to this type of support are all geared to other research topics, incompatible with those inherent to Production Engineering, which has particular features of writing and structuring texts. The purpose of this research was to adapt and assess a new tool to help Production Engineering researchers to write articles English, grounded on example- and experience-based learning. To this end, two existing tools that aid scientists to read, annotate, and write articles in English were adapted and assessed through two experiments with ten Production Engineering graduate students at Brazilian public universities. Data were collected through a questionnaire in order to identify the effect of these tools on participants learning and time required to write articles. The adapted tools provide, in addition to snippets from published articles on Production Engineering, a structure more consistent with this field of knowledge. Results indicate 90% satisfaction rate with the new tool. Also, participants reported a positive effect on their writing skills as well as an 11% reduction in their time spent on scientific writing. Therefore, the tools in question have shown great potential to assist Production Engineering researchers in writing articles; moreover, their features may be adapted to scientific writing in other fields of knowledge.

The growth of multimedia content in recent years motivated the research on audio classification and content retrieval area. In this thesis, a general environmental audio classification and retrieval approach is proposed in which higher level semantic classes (outdoor, nature, meeting and violence) are obtained from lower level acoustic classes (emergency alarm, car horn, gun-shot, explosion, automobile, motorcycle, helicopter, wind, water, rain, applause, crowd and laughter). In order to classify an audio sample into acoustic classes, MPEG-7 audio features, Mel Frequency Cepstral Coefficients (MFCC) feature and Zero Crossing Rate (ZCR) feature are used with Hidden Markov Model (HMM) and Support Vector Machine (SVM) classifiers. Additionally, a new classification method is proposed using Genetic Algorithm (GA) for classification of semantic classes. Query by Example (QBE) and keyword-based query capabilities are implemented for content retrieval.

Nessa perspectiva, a liderança tem um papel fundamental por ser capaz de mobilizar e orientar a força de trabalho para o cumprimento das metas organizacionais, uma vez que o líder pode influenciar positivamente e inspirar pessoas a dar o melhor de si em benefício da organização. O engajamento, a motivação e a cooperação que propiciam essa entrega pessoal ocorrem a partir da percepção dos liderados a respeito do comportamento do líder exemplar, o que remete à construção de vínculos de confiança. Em função disso, este trabalho teve como objetivo identificar o estilo de liderança prevalecente em uma unidade de uma instituição financeira, bem como avaliar se este estilo propicia a construção de relações de confiança entre líder e liderados. Para tanto, inicialmente foi realizado um levantamento bibliográfico sobre os temas liderança e confiança. Na sequência, foram aplicados os questionários Multifactor Leadership Questionnaire (MLQ) e Behavioral Trust Inventory (BTI) e realizadas entrevistas, a fim de obter os dados para análise. Como resultado da pesquisa concluiu-se que prevalece na unidade estudada um estilo com traços da liderança transformacional e da liderança transacional recompensa contingente. Ficou evidenciado que esse estilo de liderança constrói vínculos de confiança mútua, demonstrando que as ações do líder fomentam o reconhecimento de sua credibilidade e auxiliam na solução de dilemas de gestão, possibilitando a cooperação espontânea para o alcance dos objetivos estratégicos da instituição. / Factors as turbulence in global markets, increased competition, speed of change, complexity and uncertainty of the political, economic and social scenario bring endless challenges for organizations that seek to respond to these dynamic movements with the necessary speed in order to gain competitive advantage and ensure business sustainability. From this perspective, the leadership has a key role to be able to mobilize and guide the workforce to meet the organizational goals, once the leader can positively influence and inspire people to give their best for the organization’s benefits. Engagement, motivation and cooperation that provide this personal delivery occur from the perception of followers about exemplary leader's behavior, which refers to building trust bonds. As a result, this study aimed to identify the prevalent leadership style in a unit of a financial institution and to assess whether this style provides trust between leader and followers. Thus, it was initially performed a literature review on leadership and trust. Then, the Multifactor Leadership Questionnaire (MLQ) and Behavioral Trust Inventory (BTI) were applied and interviews were performed in order to get the data for analysis. As a result of research, it was concluded that the style with traces of transformational leadership and transactional contingent reward leadership was prevailed in the unit studied. It was evident that this leadership style builds mutual trust bonds, showing that the actions of the leader encourage the recognition of his credibility and help solving management dilemmas, allowing the spontaneous cooperation to achieve the strategic objectives of the institution.

Si la forte présence des personnages illustres et des cités antiques dans les œuvres politiques de Jean-Jacques Rousseau a été remarquée dès leur parution, leur fonction a trop longtemps été interprétée comme celle d'exemples à imiter. L'étude des multiples sources de Rousseau nous permet de mettre en lumière la complexité de ses références à l'Antiquité. Loin de présenter les grandes figures et les cités antiques comme des exemples monolithiques que le lecteur serait invité à faire revivre ou à regretter, Rousseau construit des modèles dynamiques, afin d'établir et d'explorer les « principes du droit politique», selon les termes du sous-titre du Contrat social. A partir de l'admiration pour les grands héros de Plutarque découverts dans son enfance, cette représentation se déplace dès le Discours sur les sciences et les arts vers l'étude des cités antiques, dont la réussite politique tient à ce qu'elles ont pleinement compris et exploité l'articulation fondamentale entre anthropologie et politique. C'est donc uniquement en observant comment les institutions politiques antiques prennent en charge la formation morale de l'homme que l'on peut pleinement établir les critères de fondation d'un corps politique légitime. La pensée politique antique joue ainsi un rôle considérable dans l'établissement de la distinction fondamentale entre souveraineté (pouvoir législatif) et gouvernement (pouvoir exécutif). L'étude de ces deux parties essentielles du corps politique met en évidence que la prégnance du modèle romain, plus fort que le modèle spartiate, permet à Rousseau de penser non seulement la fondation, mais encore la durée et le devenir du cor ps politique. / This dissertation conducts a systematic examination of Jean-Jacques Rousseau 's representation of Antiquity and provides a new interpretation of its meaning. Rousseau's lifelong interest in ancient Greece and Rome has so far been interpreted mainly as a personal myth, rooted in his emotional identification with examples of civic virtue. Challenging this interpretation, I analyze Rousseau's vision of Antiquity as a carefully constructed representatio n that seeks to answer key questions of early modern political thought. As he constructs his political system, Rousseau considers ancient material through a complex web of mediations, which alter his representation of Antiquity . The admiration for great men inherited from his childhood reading of Plutarch quickly turns into the construction of dynamic political models. Rousseau draws on ancient historical examples, as weil as on Plato's and Aristotle's political philosophy, to articulate his own definition of key modern political concepts such as sovereignty and body politic. In Rousseau's view ancient cities were politically successful because they fully understood the fundamental connection between anthropology and politics, placing the moral education of the citizens at the core of political action. Studying examples of ancient cities thus becomes indispensable not only to define a truly legitimate political structure, but also to design methods and practices to make it last over ti me. In this respect, the Roman Republic, whose institutions more successfully faced the challenge of history, serves as a more significant political model than Sparta. Reassessing Rousseau's representation of Antiquity thus allows usto reevaluate the place of government in his political system.
