2	Corps : Présences et Pensées du Corps dans les "Cahiers" et les oeuvres de Paul Valéry / Non communiqué Roger, Émilie 14 December 2011 (has links) Comprendre l'Esprit achoppe au Corps : la réflexion sur l'humain menée par Paul Valéry, au delà de la méthode analytique rigoureuse qu'il s'est imposé, ne peut être amputée d'une pensée de la corporalité. Précisément, de la confrontation de la pureté de l'Esprit et de la finitude du corps ancré dans la contingence du Monde jaillit une écriture de la souffrance et du manque affleurant à l'extrême de l'être, entre les limites floues d'un dedans et d'un dehors. Notre recherche tend à cerner les différentes structures scripturales du corps dans l'oeuvre de Valéry afin de révéler une « tache obscure » (ou Quatrième Corps) dans l'écart qui résiste à la transcription mais contient la clef de l'indicible. Les représentations valéryennes du corps, riches et complexes, se partagent entre une pensée organisant le corps en quatre pôles de perception (Mon-Corps, Corps de l'apparence, Corps-Machine, et Quatrième Corps) et une poétique texturisant une chair plurielle, brutalisée ou réifiée, dont les images se moulent sur une psyché prisonnière. En étudiant le mouvement entre pas et danse, le concept de la ritournelle s'impose, sur un schéma identique aux jeux d'écritures valéryens, pour comprendre les (dé)territorialisations multiples d'un corps vers le monde et vers sa profondeur. Valéry tente une cartographie ou « topologie » du corps réel et imaginaire en se référant à des outils biologiques, mathématiques (Riemann) et mythologiques (ouroboros) propices à incarner le passage de l'esprit au corps et surtout de l'ineffable zone corporelle. Enfin, l'approche phénoménologique de Husserl apporte un ultime éclairage sur les modalités d'inscription de la chair dans ses rapports intimes à autrui. / Understanding the Mind stumbles over the Body: the reflexion on the human led by Paul Valéry, beyond the strict analytical method he set for himself, cannot be severed from a thinking of corporeality. Precisely, out of the confrontation of the purity of the Mind and the finitude of the body anchored in the contingency of the World springs a writing of suffering and longing showing through the surface of the extremity of being, between the blurred limits of an inside and an outside. Our research aims to define the different scriptural structures of the body in the work of Valéry, so as to reveal a « dark stain » (or Fourth Body) in the gap that resists transcription but contains the key to the unspeakable. The Valeryan representations of the body, rich and complexe, are shared between a thinking organizing the body into four poles of perception (« Mon-Corps »,Body of appearance, Machine-Body and Fourth Body) and a poetics texturising a plural, brutalized or reified flesh whose images mold themselves around a trapped psyche. When studying the movement between step and danse, the ritornello concept imposes itself, following an outline identical to the Valeryan play on writing, to understand the multiple (de)territorializations of a body towards the world and towards its depth. Valéry attempts a mapping or « topology » of the real and imaginary body by referring to biological, mathematical (Riemann) and mythological (ouroboros) tools favourable to embodying the passage from mind to body, and especially through the ineffable bodily area. Husserl's phenomenology provides a final light on the way the flesh inscribes itself in its intimate relationship to the other.

3	Enabling loop-closures and revisits in active SLAM techiniques by using dynamic boundary conditions an local potential distortions / Viabilizante fechamento de ciclos e revistas técnicas de SLAM ativo usando condições de contorno dinâmicas e distorções de potencial locais Jorge, Vitor Augusto Machado January 2017 (has links) Robôs verdadeiramente autônomos devem conhecer o ambiente para executar tarefas complexas. Em ambientes desconhecidos o robô deve concorrentemente construir o mapa do ambiente e se localizar usando sensores proprioceptivos e exteroceptivos imprecisos. Isto é problemático, uma vez que o mapa parcial e possivelmente incorreto do ambiente será usado para corrigir erros de localização. Este problema importante da robótica móvel é conhecido como Localização e Mapeamento Simultâneos (SLAM). Quando um robô autonomamente executa o algoritmo de SLAM concorrentemente com uma estratégia de exploração, o problema passa a se chamar SLAM Ativo ou Exploração Integrada. Um dos principais desafios por trás destes problemas é o tratamento de fechamento de ciclos. Ao atravessar regiões desconhecidas ou ambientes esparsos, a pose do robô e o mapa podem não ser propriamente corrigidos por falta de informação. Quando isto acontece, as incertezas da posição do robô e do mapa aumentam, podendo levar a erros irrecuperáveis. Por outro lado, quando o ciclo é fechado corretamente, estas incertezas diminuem consideravelmente. Portanto, a escolha do caminho para explorar o ambiente pode drasticamente melhorar ou degradar a qualidade do mapeamento e da localização. Uma técnica bem conhecida de exploração de ambientes é a adaptação do problema de valor de contorno (BVP) para a equação de Laplace e condições de contorno de Dirichlet. Apesar de ser fácil de implementar, resultando em trajetórias de exploração suaves, esta técnica não endereça cuidadosamente erros de SLAM, uma vez que ela segue a descida do gradiente, o que pode não possibilitar revisitas, uma limitação crucial para o SLAM Ativo. Mesmo sendo uma técnica de exploração gulosa e direcionada a fronteiras, consideramos que a flexibilidade do BVP e condições de contorno de Dirichlet ainda são pouco exploradas. Nossa proposta é modificar o algoritmo de Exploração por BVP para executar comportamentos complexos, tais como revisitas e, em particular, fechamentos de ciclo. Apresentamos duas novas abordagens: a primeira faz uso de uma condição de contorno direcionada pelo tempo combinada a distorções de potencial para gerar comportamentos de fechamento de ciclo, além de um potencial que nunca cessa de existir, mesmo após o ambiente ter sido completamente explorado; a segunda, propicia o fechamento de ciclos aproveitando a propagação do potencial em regiões desconhecidas, através de um par dinâmico de condições de contorno que funcionam como obstáculos e objetivos virtuais. Ambas abordagens aproveitam o Esqueleto de Voronoi do ambiente para reduzir o custo computacional do algoritmo. Testes em ambientes reais e simulados usando o robô Pioneer 3DX mostram que as técnicas apresentadas apresetam melhores resultados quando comparadas a técnicas concorrentes. / Truly autonomous robots must know the environment in order to execute complex tasks. In unknown environments, the robot must construct a map and localize itself using noisy proprioceptive and exteroceptive sensors. This is problematic, since the partial and possibly inaccurate map of the environment will be used to correct localization errors. This important problem of mobile robotics is known as Simultaneous Localization and Mapping (SLAM). When a robot autonomously execute a SLAM algorithm concurrently with an exploration strategy, this problem is called Active SLAM or Integrated Exploration. One of the main challenges behind both these problems is the treatment of loop closures. While the robot traverses unknown regions or sparse environments, the robot pose and the map may not be properly corrected due to lack of information. When this happens, the uncertainties about the map and the robot pose increase, which may lead to unrecoverable SLAM errors. On the other hand, when a loop is closed successfully, these uncertainties drastically decrease. Therefore, path chosen to explore the environment can considerably improve or degrade the quality of both localization and mapping. One well known way to explore the environment is the adaptation of the Boundary Value Problem (BVP) for the Laplace Equation and Dirichlet boundary conditions. Even though it is easy to implement, resulting in smooth exploration trajectories, it does not carefully address SLAM errors, since it follows a gradient decent which not always allows revisits, a crucial limitation for Active SLAM. Despite being a greedy frontier driven exploration strategy, we consider the flexibility of the BVP and Dirichlet boundary conditions still under-explored for Active SLAM. Our proposal is to modify the BVP Exploration algorithm to execute complex exploration behaviors, such as revisits and, in particular, loop-closures. We present two new approaches: the first makes use of a time driven boundary value condition together with potential distortions to generate loop closing behaviors and a potential field that never ceases to exist, even after the exploration ends; the second enables loop closure behaviors with BVP by taking advantage of potential propagation in unknown space generated by a pair of dynamic boundary conditions functioning as virtual walls and goals. Both approaches take advantage of a local optimization that uses the Voronoi Skeleton to reduce the computational cost of the algorithm. Tests in real and simulated environments using a Pioneer 3DX show that the proposed approaches present better results when compared with competing approaches.

8	Recherches sur le système de représentations symboliques de l’art néolithique aux textes des pyramides- Origines et formation des éléments de la religion solaire de l’Egypte antique / Research on the symbolic representations system in Egypt from Neolithic art to the pyramid texts.- Origin and formation of solar religion elements in pharaonic Egypt Sweydan, Francois 28 February 2011 (has links) Dès les premières dynasties, le pictogramme fut dans l’écriture le prolongement des représentations figuratives naturalistes, logogrammes dans les palettes funéraires décorées protodynastiques. Ce constat nous porte à les mettre en correspondance avec l’art pariétal du néolithique nubien, le prédynastique égyptien, et celui des aires culturelles périphériques. La reconsidération des pétroglyphes en tant que symboles et idéogrammes, c’est-à-dire des mythogrammes autant que des logogrammes-phonogrammes polysémiques permet de dégager un système structurel de représentations symboliques universel dans la vallée du Nil. Essentiellement funéraire, il est organisé autour d’une nouvelle lecture en relation aux mythes fondateurs de l’Œil d’Horus/solaire, s’exprime dans des rites primitifs de revivification, de renaissance, néolithiques et prédynastiques, explicités ensuite durant les premières dynasties sur des tablettes, des sceaux-cylindres votifs, et l’onction du mort avec les sept huiles canoniques et, enfin, dans les Textes des Pyramides. Contrairement à l’idée commune d’opposition des notions de Nature-Culture, il est question de les conjuguer, de réconcilier la dualité non binaire et de voir, par exemple, les fonctions héliotrope et/ou héliophore des animaux du bestiaire soudanien, avec Sokar le faucon funéraire, les garants bienveillants des métamorphoses et de renaissance du soleil/des défunts, par ailleurs, félidés, canidés, antilopes…, investis du numineux des divinités tutélaires. À la lueur d’une nouvelle lecture du mythe “osirien” primitif de métamorphose, nous reconsidérons les conceptions sur le sacrifice animal sur des bases d’anthropologie religieuse. Loin d’une maîtrise et soumission de la nature, et d’un diffusionnisme, l’interculturalité de la pensée mythique archaïque première dans la vallée nubiano-égyptienne et des régions périphériques multiethniques implique, vis-à-vis du monde naturel et des forces spirituelles numineuses, la transculturalité des conceptions solaires et le partage pluriculturel, transhistorique des croyances résurrectionnelles polycycliques. Ainsi, les pétroglyphes d’animaux, les scènes de chasse animale, les représentations de barques, de sandales, etc., sont de nature funéraire votive, apotropaïque. / Since the beginning of the first dynasties, the pictogram in writing was the extension of naturalistic figurative representations, logograms in the decorated funerary protodynastic palettes. This statement carry us to link them with the parietal art of Neolithic Nubia, the egyptian Predynastic, and peripheral cultural areas. We have reconsidered the petroglyphs as polysemic symbols and ideograms, i.e. mythograms as well polysemic logograms-phonograms, allowing us to draw up a structural system of symbolic representations, universal in the Nile valley. Basically funerary, the system is organised around a new reading in connection with the founding of the ‘Eye of Horus’/solar myths, and express itself in primitive Neolithic and Predynastic rites of revivification, rebirth, more explicit afterwards during the first dynasties on labels, votive cylinder-seals, and anointing the deads with the seven holy canonical oils, finally in the Pyramid Texts. Contrary to the common idea which opposite the Nature-Culture notions, there is some question to combine them, to reconcile the non-binary duality and to see, for example, the heliotrope functions and/or heliophore animals of the sub-Saharan bestiary, with Sokar the funerary hawk, the benevolent guarantors for the rebirth and metamorphosis of the sun/deads; otherwise felids, canids, antelopes…, invested by the numinous of the protecting divinities. In consequence of a new reading of the primitive ‘osirian’ myth of metamorphosis, we have reconsidered the conceptions about animal sacrifice on the basis of religious anthropology. Far from bringing under control and submission of nature, and diffusionnism, the intercultural (cross-cultural) of the first archaic mythic thought in the multi-ethnic nubian-egyptian valley and associated neighbouring areas involves, towards the natural world and the numinous spiritual strengths, the cross-cultural of solar conceptions and multicultural, trans-historic sharing of the polycyclic resurrectional believes. Thus, the animal petroglyphs, cynegetic scenes, boats and sandals representations, etc., are of funerary votive, apotropaic nature.
