Em meio à rápida propagação de tecnologias de mídia que tornam possível produzir, arquivar, se apropriar e recircular conteúdo informacional, uma cultura participativa vem emergindo nos dias atuais. Uma lógica de colaboração se faz presente, viabilizada por ferramentas técnicas que estruturam o conhecimento em rede. Nesse contexto, o museu, enquanto agência de representação sociocultural, se esforça no sentido de atualizar-se. Nesta dissertação, sugere-se que a interação participativa de caráter social é um caminho para renovar e ampliar as narrativas culturais elaboradas pelos museus, em sua relação comunicacional com o público. Foi elaborado, então, o sistema Revelar: um modelo preliminar que se propõe a investigar o design de participação em contexto museológico. O sistema, que tem como palco de ações o complexo do Jardim Botânico do Rio de Janeiro, pressupõe a participação de estudantes de Ensino Médio em uma atividade programada pela equipe do Museu do Meio Ambiente. A matéria de contribuição dos alunos participantes é a fotografia produzida a partir do uso de dispositivos móveis / A participatory culture is emerging amid the fast propagation of media technologies that make it possible to produce, archive, appropriate and recirculate informational content. A collaboration logic is observed, made feasible by technical tools that structure the networked knowledge. In this context, the museum performs an effort in order to update itself as an agency of sociocultural representation. In this thesis, we maintain that the social participatory interaction is a path to renew and expand the cultural narratives developed by museums, in respect to its communicational relationship with the audience. Therefore, a system called Reveal was devised: a preliminary model which aims at investigating participation design within a museological context. The system, which is located in Rio de Janeiro Botanical Garden, presupposes the participation of high school students in an activity elaborated by the Environment Museum team. Participants contribute with photographs captured with mobile devices.

Le cinéma n’enregistre pas seulement ce qui existe: il arrive qu’il fabrique des objets pour les filmer. Des « simulacres » qui peuvent être aussi bien des parodies d’œuvres d’art que des machines à voyager dans le temps. Comment penser ces objets improbables, excroissances filmiques souvent kitsch, qui dénoncent au sein du film même ses artifices fictionnels? Comment pensent-ils le cinéma, ses spécificités et ses relations avec les arts plastiques? À partir de l'exemple du cinéma français des années 1960, ce travail de thèse s’est donné pour objectif de replacer ces objets dans la culture visuelle, de les analyser comme des carrefours artistiques et de débattre des questions théoriques qu’ils soulèvent, notamment de la capacité du cinéma à mettre en fiction le pouvoir des autres arts. Au point de rencontre entre la théorie artistique et la fiction cinématographique, l’histoire de ces objets hybrides permet de comprendre que le cinéma peut se faire historien d’art et que l’histoire de l’art est elle-même une longue suite de fictions sur les pouvoirs attribués aux objets. En cela, ces simulacres cinématographiques apportent des sources inédites à l’historien des arts visuels. / Not only do films record what exists: they sometimes create objects to be filmed. These « simulacra » can just as well be parodies of art works or time machines. How do we think about these peculiar objects, all-too-often kitsch filmic excressences, which serve to highlight fictional artifice? Moreover, how do we think about cinema, in both its specificities and its relation to Plastic Arts? Looking through the lens of French cinema in the 1960's, this thesis intends to reconsider these objects in the context of visual culture, to analyse them as artistic crossroads, and to debate the theoretical issues they raise, most particularly the ability of cinema to turn into fiction the power of other arts. At the meeting point between artistic theory and cinematographic fiction, the history of these hybrid objects allows one to understand that cinema can perform the role of an art historian, and that art history is itself a succession of fictions about the power assigned to objects. As such, these cinematographic simulacra provide visual arts historians with unexpected sources.

Cette thèse a pour double objectif d'analyser l'activité individuelle et collective d'enseignants, parents, animateurs et enfants dans la pratique des devoirs et d'en envisager les conditions de transformation. Inscrite dans le programme du « cours d'action », cette recherche a consisté : a) à analyser l'activité dans deux études de cas référant à des situations de devoirs, d'une part en classe et dans un dispositif péri-scolaire, et d'autre part en classe et dans une famille, à partir d'enregistrements vidéoscopés et de séances en autoconfrontation ; b) à concevoir un environnement de formation à destination d'enseignants, parents et animateurs à partir d’artefacts vidéo élaborés grâce aux données initialement recueillies ; c) à mettre en œuvre cet environnement de formation en confrontant les participants à ces artefacts vidéo et en analysant leur activité. Les résultats sont analysés en tant qu'ils réfèrent à deux volets de la recherche : empirique et technologique. En ce qui concerne le volet empirique, les résultats ont mis en évidence que malgré la séparation spatio-temporelle des situations, il était possible d'identifier des dimensions collectives de l'activité dans la pratique des devoirs, liées à la circulation des enfants et objets techniques. Ces derniers ont été considérés comme des « interfaces » permettant l'articulation de l'activité des adultes. Cela a permis de pointer : a) l'existence d'une culture partagée entres les enseignants, parents et animateurs qui expliquerait en partie la pérennité de la pratique des devoirs ; b) des éléments d'une culture spécifique à chacune des catégories d'acteurs ; c) des asymétries étant donné que l'activité de l'enseignant a eu beaucoup plus d'influence sur la dynamique de l'activité collective que n'en ont eu les autres adultes ; d) des difficultés rencontrées par les parents et animateurs dans l'encadrement du travail des enfants ; e) une influence importante des objets techniques dans la dynamique de l'activité collective. Dans ce cadre, ces situations ont été analysées comme offrant un faible potentiel d'apprentissage pour les enfants. Au plan technologique, il s'est agi d'identifier le potentiel de l'environnement de formation pour ce qui est d'aider les acteurs à s’approprier les dimensions collectives de leur activité et d'envisager des situations plus propices aux apprentissages chez les enfants. Pour cela, leur activité a été analysée lorsqu'ils étaient confrontés à l'épisode de l'artefact vidéo qui référait à l'espace-temps auquel, dans la pratique, ils n'avaient habituellement pas accès. Les résultats ont mis en évidence des processus cognitifs référant à une prise de conscience, chez les participants, des dimensions collectives de l'activité. Parallèlement, des limites sont apparues en ce qui concerne le potentiel de l'environnement de formation à encourager, chez ces mêmes acteurs, de nouvelles actions. Ces résultats, analysés en lien avec les spécificités des artefacts, leur modalité d'utilisation ainsi que la culture des acteurs, ont donné lieu à des perspectives de transformation de l'environnement de formation. / The dual aim of this thesis is to analyze the individual and collective activity of teachers, parents, pupil support workers and children when dealing with school assignments and to envisage the conditions for the transformation of this practice. This study draws on the "course-of-action" research program and involved a) using video recordings and self-confrontation sessions to analyze the activity of the participants in two case studies pertaining to school assignment situations; one case study was conducted in the classroom and during extracurricular activities the other in the classroom and at home; b) designing a training environment for teachers, parents and support workers based on video artifacts which were created using data collected at the outset; c) implementing this training environment by confronting the participants with the video artifacts and analyzing their activity. The results we examined refer to the empirical and the technological aspects of the research. As far as the empirical aspect is concerned, the results show that despite the spatial and temporal separation of the situations, collective dimensions to the school assignment activity could be identified relating to the circulation of the children and the technical devices. The latter acted as “interfaces” making it possible to articulate the activity of the adults. This has enabled us to demonstrate: a) the existence of a culture shared by teachers, parents and pupil support workers which partially explains the durability of the practice of school assignments; b) cultural elements specific to each category of actors; c) certain asymmetries given that the teacher’s activity has a much greater influence on the collective action than the activity of the other adults; d) difficulties experienced by parents and pupil support workers when supervising the children’s work; e) a strong influence of the technical devices on the dynamics of the collective action. In light of these observations, we consider that the situations contributed very little to enhancing the children’s learning potential. The technological aspect involved identifying the training environment’s potential for helping the actors to appropriate the collective dimensions of their activity and to envisage other situations which would be more conducive to learning. To do this, their activity was analyzed during a confrontation with the episode of the video artifact referring to a temporal and spatial setting that, in practice, they did not usually have access to. The results highlight cognitive processes indicating that the participants had become more aware of the collective dimensions of the activity. At the same time, it emerged that the training environment had a limited potential for inciting these same actors to imagine new actions. These results, analyzed in relation to the specificities of the artifacts, the use made of them and the culture of the actors have opened up new perspectives for the transformation of the training environment.

Current design models, approaches and theories are highly fragmented, have seldom been compared with one another, and rarely attempted to be consolidated. Novelty is a measure of creativity of engineering products and positively influences product success. Using physical laws and effects for designing can improve the chances of creativity but they cannot be used directly owing to their inadequate current representations. It is important to address activities, outcomes, requirements and solutions in designing. Conceptual design is an early phase in engineering design and needs to be supported better. A systematic approach for designing often increases effectiveness and efficiency. Thus, the broad objective of this thesis is to develop and validate a comprehensive understanding of how designing occurs during the conceptual phase of engineering design, and to support variety and novelty of designs during this phase. The approach followed is: (a) formulate and validate an understanding of novelty and its relationships to the designing constructs, in current designing, and(b)develop and validate a support, founded on the current designing, to improve novelty. The understanding and the support are addressed, respectively, through an integrated model and a systematic framework for designing; the model and the framework comprise activities, outcomes(including laws and effects), requirements and solutions. An integrated model of designing, GEMS of SAPPhIRE as req-sol is developed by combining activities(Generate, Evaluate, Modify, Select– GEMS), outcomes (State change, Action, Parts, Phenomenon, Input, oRgans, Effect–SAPPhIRE), requirements (req) and solutions (sol), identified from a comprehensive survey of existing design models and approaches. Validation of SAPPhIRE model with existing systems indicates that the model can be used to describe analysis and synthesis, both of which together constitute designing. Validation of the integrated model using existing videos of design sessions, to check if all its constructs are naturally used in designing, reveals that:(a) all the constructs are naturally used;(b) not all the outcomes are explored with equal intensity;(c) while high numbers of action and parts are observed, only low numbers of phenomenon, effects and organs are found. Empirical study using another set of design sessions to study the relationships between novelty and the outcomes reveals that novelty of a concept space depends on the variety of the concept space, which in turn depends on the variety of the idea space explored. Novelty and variety of a concept space also depend on the number of outcomes explored at each abstraction level. Thus, phenomena and effects are also vital for variety and novelty. Based on the above, GEMS of SAPPhIRE as req-sol framework for designing is proposed. The framework is divided into: Requirements Exploration Stage(RES) and Solutions Exploration Stage(SES). In RES and SES, requirements and solutions respectively at all the abstraction levels including SAPPhIRE are generated, evaluated, modified and selected. The framework supports task clarification, conceptual and early embodiment phases of designing, and provides process knowledge. Comparison of the framework against existing design models, theories and approaches reveals that:(a) not all existing models, theories and approaches address activities, outcomes, requirements and solutions together;(b) those that address all these constructs together do not make a distinction between requirements and solutions; and(c) no model or approach explicitly addresses novelty. The usability of the framework and Idea-inspire is assessed by applying them in an industrial project for designing novel concepts of lunar vehicle mobility system. The use of this combined support enables identification of critical requirements, development of a large variety of ideas and concepts. One of these concepts is physically and virtually modelled, and tested, and is found to satisfy all the requirements. A catalogue of physical laws and effects is developed using SAPPhIRE model to provide assistance to designers, especially for phenomena, effects and organs. Observations found during this development are reported. A comparative validation of the framework and the catalogue for their support to design for variety and novelty is done using comparative observational studies. Results from the observational studies reveal that the variety and the novelty of concept space improve with the use of the framework, or with the frame work and the catalogue, as compared to variety and novelty with no support.

Les travaux présentés dans cette thèse portent sur la conception et le dimensionnement de composant magnétique dédié au transfert d'énergie sans contact pour des applications ferroviaires de type tramway. Cette famille de composant présente un comportement fortement inductif. Un convertisseur à double fréquence de résonance est utilisé pour l'alimenter et compenser l'énergie réactive du coupleur. Pour parvenir à dimensionner ce composant et son convertisseur associé, un outil d'aide au dimensionnement a été mis au point. Celui-ci est basé sur des modèles analytiques du composant magnétique et de la structure d'électronique de puissance. Une fois le dimensionnement réalisé, une étude des pertes, dans les bobinages et les circuits magnétiques, est réalisée par simulation numérique en utilisant la méthode d'homogénéisation (représentation macroscopique des éléments avec des propriétés électromagnétiques complexes). Puis, la modélisation du comportement thermique du système est présentée afin de garantir la température de fonctionnement désirée. Afin de valider l'approche de dimensionnement et les outils mis en place, des expérimentations ont été menées sur des prototypes de 1,6 et 100 kW. Les résultats obtenus ont montré la précision et la pertinence de l'approche théorique. Cette étude valide la faisabilité de ce type de système forte puissance. / The works presented in this thesis deal with the design and the sizing of magnetic component dedicated to contactless energy transfer for railway application like tramway. This family of component presents a strongly inductive behavior. A double resonance converter is used to supply and compensate reactive energy of transformer. In order to design this component and its associated converter, a design tool has been implemented. This one is based on analytical models of magnetic component and power electronic converter. One time designing realized, a study of losses, in windings and in magnetic cores, is realized by numerical simulation by using homogenization method (macroscopic representation of elements with electromagnetic complex properties). Then, the establishment of a model of thermal behavior of system is presented in order to guarantee desired working temperature. In order to check designing approach and tools, experimentations have been performed on prototypes of 1.6 and 100 kW. Obtained results show the accuracy and relevance of theoretical approach. Moreover, this study confirms the feasibility of this kind of high power system.

Die vorliegende Arbeit befasst sich mit der Entwicklung und Umsetzung von Methoden und Werkzeugen zur Bereitstellung von Modellen und Randbedingungen für die Konstruktion individueller Langzeit-Knochenimplantate (Konstruktionsvorbereitung). Grundlage dabei ist, dass die Planung aus medizinischer Sicht z.B. durch einen Chirurgen und die Konstruktion unter technischen Aspekten z.B. durch einen Konstrukteur getrennt erfolgt. Hierfür wird ein erarbeitetes Planungskonzept vorgestellt, welches sowohl die geplanten geometrischen Merkmale, als auch weiterführende Metadaten beinhaltet (Randbedingungen). Die Übergabe dieser Planungsdaten an die Konstruktion erfolgt über eine dafür entworfene Formatbeschreibung im Kontext der Schnittstelle zwischen Mediziner und Ingenieur. Weiterführend wird die Notwendigkeit von speziellen Funktionen für die Konstruktion von individuellen Implantaten in der Arbeitsumgebung des Konstrukteurs (z.B. Modelliersystem – CAD) am Beispiel der konturlinienbasierten Modellrekonstruktion erörtert. Die gesamtheitliche Basis bildet eine durchgängig digitale Prozesskette zur Datenaufbereitung, Konstruktion und Fertigung. Die Anwendbarkeit der Methoden und zweier umgesetzter Demonstratoren wurde innerhalb eines interdisziplinär angelegten Projektes am realen Patientenfall bestätigt.
