Abstract:

This dissertation investigates thematic unities within Robert Morris's seemingly disparate body of work. It demonstrates the thematic similarities, structural continuities and formal associations used throughout his art despite the great diversity of the media employed. It departs at times from a strictly chronological approach because its primary purpose is to explore how one work begets another or one style morphs into the next. The research involved extensive archival work studying unpublished correspondence and texts, contracts, drawings and emails, along with traditional sources like books, interviews, lectures and Morris's own published criticism and texts. The author also examined many original artworks or reproductions of unavailable ones. Chapter One discusses the definition and problem of style, establishment of artistic influences, and Morris's reluctance to accept traditional boundaries. Chapter Two addresses the choreography and its task-oriented vocabulary, and Morris's minimalist sculptures, examining his ideas on process and the phenomenology of perception. Chapter Three is devoted to Morris's concept of space and exploration of the horizontal as a spatial vector. It studies his interest in structural continuity throughout his lead, mirror and felt works, and touches on both the physical space of the sculptures, and the virtual space of the mirrors, as well as the fleeting evanescent space of the steam. His elaborations on “how to make a mark” are considered, too, from the Blind Time drawings, riding on horseback and body-part imprints, to language and the natural world. Chapter Four turns to Morris's philosophical investigations, his studies of language and imagery—some apocalyptic—and his increasing concern with destructive contemporary attitudes. Chapter Five takes up the works of the last two decades, his interest in memory and his growing cultural pessimism. Finally, analyzing one of the most recent works, the Conclusion makes clear that through its recurrent timeliness, Morris's art achieves a certain sublimity which aims towards a suspension of time—a timelessness.

Abstract:

Thesis (DTh (Systematic Theology and Ecclesiology))—University of Stellenbosch, 2008.<br>This study offers an overview, interpretation and critical evaluation of the theology of the Lutheran American theologian Robert Jenson. The first aim is to give an outline of his theology in such a way that the importance of the relation between God and time in his thought will become clear in this process. This study will therefore focus on specific themes in his theology and the implications for the current theological debate on time, eternity, history and God. The title was also the title of Jenson’s own early study of the work of Karl Barth, Alpha and Omega. Jenson’s theology is ecumenical by driven from the beginning to the end. He tries to formulate a theology for the one united church of the future. In his theology he thus focuses on early writers, the church fathers and on ecumenical confessions such as Nicea. He wants to get clarity why the church differs on certain points and investigates where it all started. He then brings his theology in connection with current Orthodox theologians, as well as with the Western theologians of different church traditions and tries to build on the common factors between them. His theology has an ecumenical aim, but it is first and foremost a theology written in reaction to postmodernism and especially the nihilism of his Western and primarily North-American cultural context. To find answers to these (ecumenical and nihilistic) questions, Jenson focuses on mainly three themes that will be discussed in this study: (1) the relation between time, eternity and Trinity, (2) the trinitarian identity and character of God, and (3) the importance of the narrative nature of theology. Jenson appropriates much of Karl Barth’s thought on the Trinity and on the Trinity’s relation to time and eternity but he draws much more radical implications and consequences. He therefore differs from Barth on these issues at critical points. Jenson stands in the tradition of eschatological and trinitarian theologians of the previous century and he builds his theology around these foci in order to serve his ecumenical aim. Finally the critical question is also asked whether and to what extent Jenson succeeds in his aim. It looks at the specific contributions Jenson made and which questions still remain unanswered regarding this key question for Christian faith, thought and life.

Le présent texte d’accompagnement de l’exposition de maîtrise en arts visuels intitulée « Le tambour métallique : paradigme instrumental d’un espace sonore temporaire » approfondit les différentes étapes qui ont amené le candidat à ce projet de recherche. Du travail d’atelier jusqu’au studio de son, ce texte témoigne de la recherche effectuée pour éclaircir le phénomène de la production sonore à travers l’étude des notions fondamentales d’acoustique. Il poursuit avec le récit de la réalisation d’une sculpture-instrument, origine du paradigme de recherche et rend enfin compte de la méthodologie utilisée afin de construire les séquences sonores du projet. De plus, les concepts sociaux et historiques qui conditionnent la nature des projets du candidat y sont exposés : de la persistance de la sensation d’ennui chez l’être humain, en passant par la volonté affichée des avant-gardes musicales de la première moitié du vingtième siècle, de renouveler la matière sonore de l’art musical, jusqu’à l’éclatement de la notion traditionnelle de la sculpture vers une spécificité multisensorielle.<br>Québec Université Laval, Bibliothèque 2019

Full text

Abstract:

Au cours des années cinquante et au début des années soixante, plusieurs critiques d’art proclamaient que la période des combine-paintings de Robert Rauschenberg était une renaissance du mouvement révolutionnaire dada. En effet, dans plusieurs articles de l’époque, on note une utilisation fréquente du terme "néo-dada" pour faire référence à la production de Rauschenberg. Au milieu des années soixante, cependant, une nouvelle tendance critique émergeait condamnant cette catégorisation. Les tenants de cette nouvelle orientation voyaient Rauschenberg non plus comme un néo-dada mais comme un précurseur du Pop. Tout en reconnaissant la validité de ces deux positions critiques, je tenterai de démontrer, dans les pages qui suivent, que ni l’une ni l’autre expliquent de façon adéquate la période des combine-paintings et le projet artistique qui l’a initiée. Après avoir examiné les points de vue de quelques représentants de ces deux tendances antagonistes, je démontrerai que la valeur essentielle des combine-paintings ne peut être reliée ni au dada ni au Pop. En effet, à la différence du mouvement dada qui rejetait l’institution de l’art et du mouvement Pop qui s’intégrait, d’une façon cynique, à celle-ci, les combine- paintings de Rauschenberg s’inscrivent dans l’institution de l’art de manière à la subvertir et reformule ainsi le projet de l’avant-garde historique qui consistait à combler la brèche entre le statut autonome de l’art et la vie quotidienne. Signatures : Louise Gauthier: Elliott<br>During the late 1950s and early 1960s, many critics believed that Robert Rauschenberg’s combine-painting period was a revival of the revolutionary Dada movement. Indeed, in many articles, critics referred to the combines as "neo-dada". In the mid 1960s, however, a new wave of criticism began to surface which strongly criticized this categorization. Rather than considering Rauschenberg as a neo-dadaist, these critics saw him as a precursor to Pop. The purpose of this paper will be to show that while both critical perspectives contain some elements of truth, neither one adequately explains the combine-paintings and the basic artistic project that motivated them. After examining the points of view defended by some representatives of these opposed perspectives, I shall argue that the essential value of Rauschenberg’s combine-paintings does not lie in their relationship to either Dada or Pop. Unlike Dada’s total rejection of the institution of art in bourgeois society and Pop art’s cynical acceptance of it, Rauschenberg’s combine-paintings work within the institution of art in order to subvert it, thus reformulating the historical avant- garde’s unfinished project of breaking down the distinction between art as an autonomous entity and day-to-day life.<br>Montréal Trigonix inc. 2018

Abstract:

This thesis examines the works of three ‘forgotten’ British artists, working from the late nineteenth century and well into the 1920s. In a period which saw momentous changes associated with the onset of modernity, artworks appeared to speak of revivalism, tradition, even nostalgia, rather than the new. Thomas Cooper Gotch, Robert Anning Bell and Frederick Cayley Robinson shared an interest in the spiritual, the unseen and immaterial, which they expressed through representations of women, placing faith, broadly, in ‘the feminine’ as synonymous with humanity’s neglected ‘spirit’ in the modern, materialistic world. The eclectic and contradictory nature of the artworks examined, their complex and ambiguous representations of womanhood and female spirituality were expressive of the condition of modernity in its rich, varied forms. These artworks are analysed in the context of an important historical moment for the feminist movement, since all three artists addressed the explosion in female agency related to contemporary feminism, the ‘gender crisis’ and the Suffragette movement. By placing artworks in this context, I have attempted to bring women, their presence in the public sphere and visual culture, their discovery of a ‘feminist voice’ in this period, into the frame. Women imagined invigorating movements, from the confines of the domestic interior into the airy heights of mountain tops, using languages of righteousness and joyous expectancy, and the artworks examined provide visual analogues and commentaries on these feminist possibilities and new imaginative aspirations. While all three artists mediated the visual ‘types’ of womanhood available within art languages, they created quite distinct images of women. Representations range from Gotch’s female Messiah, where woman’s spiritual power originates in her innocence and purity, Bell’s images of Amazonian strength allied with a closer female relationship with nature, to more occult versions in Cayley Robinson’s paintings, related to theosophy. The artworks participated in a tremendous moment of hope for women in their endeavours toward autonomy and fulfilment. In presenting women’s spiritual role as humanity’s redeemer, these paintings reveal how art may envisage intangible forms of spirituality and emancipatory possibilities.

Abstract:

In the past, pastoral-therapeutic support was mainly approached only from the functioning of the left hemisphere of the brain. This implies that pastoral therapists mainly interacted with people in therapy at an intellectual-analytical level under modernistic influence. Since man's destitution and need changes along with time, it is essential for pastoral therapists/counsellors to supplement and adapt their modus operandi and strategies if they wish to remain relevant regarding their pastoral dealings with people. In this study the researcher attempted to formulate from the Scriptures a basis theory regarding the role of music as a whole-brain strategy in inner change. For the sake of a more holistic approach, a meta-theoretical investigation was also undertaken. To confirm the basis and meta-theoretical information, researcher entered the living reality of seven individuals during which a qualitative research was done. The results of the study, according to which the basis and meta-theoretical perspectives were placed in hermeneutical relation to one another, led to practice-theoretical guidelines within the subject domain of Practical Theology regarding the role of music as a whole-brain strategy in inner change.<br>Thesis (Ph.D. (Pastoral))--North-West University, Potchefstroom Campus, 2008.

Abstract:

La présence d'éléments de la tradition classique chez Robert Venturi et Ricardo Bofill origine dans la volonté de doter l'architecture actuelle d'un langage qui lui redonne un pouvoir d'évocation et une richesse sémantique jugés déficients dans la production moderniste. Le langage classique est l'objet chez les deux architectes d'un projet de remise à jour par une transformation physique et sémantique dont le modèle opérationnel est basé sur la sémiotique d'origine linguistico-saussurienne. L'entreprise de Venturi et Bofill est marquée d'insuffisances qui peuvent originer dans la spécificité du langage architectural ou dans les faiblesses du modèle opérationnel d'une sémiotique architecturale encore imparfaite. Ces problèmes n'entachent cependant pas la valeur du but poursuivi, qui s'inscrit dans une longue tradition humaniste concevant l'architecture comme un art au service de l'homme.<br>Montréal Trigonix inc. 2018

Abstract:

<p>The aim of this paper is to apply Robert N. Bellahs theory of civil religion, within a Swedish societal context. Bellahs theory was designed in, and influenced by American culture. Therefore, the “translation” of Bellahs theory does not come without problems. A methodological discussion concludes with methods focusing on national self-conceptions. Through this method, the Swedish social democratic notion of the “folkhem” can be related to the notions included by “the American way of life”. The “folkhem” as well as “the American way of life” includes ideas of the nation, made up by specific historical events, in both nations. Those ideas are vital parts of the national self conception in both nations. Historical premises are constantly reborn through the rhetorical reinterpretation, and through the eyes of Bellah, the notion of the folkhem creates a national embracive, ethical value system. The notion of the folkhem still is viable in the Swedish society. Contemporary use of the folkhem-notion is discerned by the threats of globalization and neoliberlismic tendencies. In the light of these threats, the folkhem-notion includes the preservation of Puritanism ideals.</p><p> </p>

While decision-making is generally conceived as the cognitive ability of individual agents to select a belief based only on their preferences and available information, collective decision making is a decentralized cognitive process, whereby an ensemble of agents gathers, shares, and processes information as a single organism and makes a choice that is not attributable to any of its individuals. A principled selection of the rules governing this cognitive process allows the designer to define, shape, and foresee the dynamics of the swarm.We begin this monograph by introducing the reader to the topic of collective decision making. We focus on artificial systems for discrete consensus achievement and review the literature of swarm robotics. In this endeavor, we formalize the best-of-n problem—a generalization of the logic underlying several cognitive problems—and define a taxonomy of its possible variants that are of interest for the design of robot swarms. By leveraging on this understanding, we identify the building-blocks that are essential to achieve a collective decision addressing the best-of-n problem: option exploration, opinion dissemination, modulation of positive feedback, and individual decision-making mechanism. We show how a modular perspective of a collective decision-making strategy allows for the systematic modeling of the resulting swarm performance. In doing so, we put forward a modular and model-driven design methodology that allows the designer to study the dynamics of a swarm at different level of abstractions. Successively, we employ the proposed design methodology to derive and to study different collective decision-making strategies for the best-of-n problem. We show how the designed strategies can be readily applied to different real-world scenarios by performing two series of robot experiments. In the first series, we use a swarm of 100 robots to tackle a site-selection scenario; in the second series, we show instead how the same strategies apply to a collective perception scenario. We conclude with a discussion of our research contributions and provide futuredirection of research.<br>Doctorat en Sciences de l'ingénieur et technologie<br>info:eu-repo/semantics/nonPublished

Abstract:

Thesis (S.M.)--Massachusetts Institute of Technology, Dept. of Aeronautics and Astronautics, 2007.<br>Includes bibliographical references (p. 165-169).<br>This thesis describes the design and performance results for the P-NMR fault tolerant avionics system architecture being developed at Draper Laboratory. The two key principles of the architecture are robust software partitioning (P), as defined by the ARINC 653 open standard, and N-Modular Redundancy (NMR). The P-NMR architecture uses cross channel data exchange and voting to implement fault detection, isolation and recovery (FDIR). The FDIR function is implemented in software that executes on commercial-off-the-shelf (COTS) hardware components that are also based on open standards. The FDIR function and the user applications execute on the same processor. The robust partitioning is provided by a COTS real-time operating system that complies with the ARINC 653 standard. A Triple Modular Redundant (TMR) prototype was developed and various performance metrics were collected. Evaluation of the TMR prototype indicates that the ARINC 653 standard is compatible with an NMR and FDIR architecture. Application partitions can be considered software fault containment regions which enhance the overall integrity of the system. The P-NMR performance metrics were compared with a previous Draper Laboratory design called the Fault Tolerant Parallel Processor (FTPP). This design did not make use of robust partitioning and it used proprietary hardware for implementing certain FDIR functions. The comparison demonstrated that the P-NMR system prototype could perform at an acceptable level and that the development of the system should continue. This research was done in the context of developing cost effective avionics systems for space exploration vehicles such as those being developed for NASA's Constellation program.<br>by Brendan Anthony O'Connell.<br>S.M.

Abstract:

This study analyses the invisible forms of repression in the Bolivian art system by interpreting Roberto Valcárcel’s artwork in the light of Herbert Marcuse’s ideas on repression and liberation as expounded in Eros and Civilization. It considers, on the one hand, Valcárcel’s artwork in relation to the liberating role that Marcuse attributes to art (via phantasy, polymorphous eroticism, and Orphic paradigm). On the other hand, it explores the strategies devised by Valcárcel against repression, such as self-promotion, multiple texts, play, humour and unmasking certain repressive truths. The reading of Valcárcel’s work via Marcuse is supported by archival research from contemporary newspapers, exhibition documentation and Bolivian art history, which provide relevant information about the sorts of latent repression to which Valcárcel’s artworks responds. The dissertation is organised in five chapters in which examples of repressive beliefs are unveiled. Chapter One examines El Movimiento Erótico (The Erotic Movement, 1983) and the manifold strategies used by Valcárcel to escape the traps of a presumed type of sexual liberation (sexist and genital oriented) and capitalism’s culture industry. Chapter Two discusses artworks where the intentional construction of open meaning challenges the norm of a univocal creation and consumption of art. Chapter Three studies some of Valcárcel’s humorous identities in contrast with the dramatic, and overly serious self-perception of Bolivians artists. Chapter Four explores Valcárcel’s use of play, black humour and deceit as effective devices to escape hidden authoritarianism in society during dictatorial regimes. Chapter Five analyses how Valcárcel’s work unveils the latent repression in the idealisation of indigenous heritage through play and anti-thesis. The dissertation introduces a new topic into the study of art in Bolivia – veiled repression – at the same time that it sheds light on the potential of the artwork of Roberto Valcárcel to open new ways of historicizing and thinking about art in Bolivia.

Abstract:

This dissertation deals with frequency domain identification of linear dynamic systems in a deterministic set-up. Various untuned algorithms are suggested, including one which is robustly convergent and asymptotically optimal (in n-width sense) for a finite model order. The suggested algorithms can easily be implemented in commercially available software for convex optimization.

Abstract:

Swarm robotics is an emerging field that is expected to provide robust solutions to spatially distributed problems. Human operators will often be required to guide a swarm in the fulfillment of a mission. Occasionally, large tasks may require multiple spatial swarms to cooperate in their completion. We hypothesize that when latency, bandwidth, operator dropout, and communication noise are significant factors, human organizations that promote individual initiative perform more effectively and resiliently than hierarchies in the cooperative best-m-of-n task. Simulations automating the behavior of hub-based swarm robotic agents and groups of human operators are used to evaluate this hypothesis. To make the comparisons between the team and hierarchies meaningful, we explore parameter values determining how simulated human operators behave in teams and hierarchies to optimize the performance of the respective organizations. We show that simulation results generally support the hypothesis with respect to the effect of latency and bandwidth on organizational performance.

Abstract:

Des protocoles couvrant l'ensemble des étapes de la micropropagation depuis le conditionnement des pieds-mères, et l'introduction in vitro des explants primaires jusqu'à l'enracinement et le sevrage des plantules, ont été mis au point, en attachant une attention toute particulière à l'obtention d'un clonage efficace à long terme à partir de matériel juvénile et adulte. A cette occasion, des variations du mode de croissance des pousses développées in vitro correspondant à une disparition progressive de la croissance rythmique endogène caractéristique de l'espèce, ont été observées. L'étude des conditions permettant leur apparition a montré le rôle primordial de la BA, en présence de BA, l'importance de l'alimentation azotée en tant que facteur de contrôle du modèle de croissance. La réalisation de bilans azotes (n total, n insoluble, n soluble, n minéral, acides aminés et amides libres) au sein des vitroplants, a permis d'associer l'apparition des différents modes de croissance décrits à une accumulation d' n soluble (no#3#, nh#4#+, asparagine, arginine, proline) dans les tiges feuillées, indépendamment des effets induits par l'introduction in vitro elle-même. Ces dosages ont également montré l'importance du cal basal qui assure l'interface entre le milieu de culture et la tige feuillée. Diverses hypothèses permettant d'expliquer le rôle de l'azote dans les mécanismes de contrôle de la croissance rythmique du chêne, ont été proposées

Abstract:

Este trabalho apresenta o desenvolvimento, implementação e análise de técnicas de controle H 'INFINITO' não lineares para robôs manipuladores subatuados, sujeitos a incertezas paramétricas e distúrbios externos. Na primeira parte, duas abordagens são consideradas para robôs manipuladores individuais subatuados. A primeira abordagem consiste em representar robôs manipuladores como um sistema não linear na forma quase-linear com parâmetros variantes e utilizar técnicas de controle H 'INFINITO' para sistemas lineares a parâmetros variantes baseadas em desigualdades matriciais lineares. Na segunda abordagem, uma solução explícita do problema de controle H 'INFINITO' não linear para robôs manipuladores é encontrada via teoria dos jogos diferenciais. Com este mesmo procedimento, implementam-se também os controles misto H'IND.2'/H 'INFINITO' não linear, adaptativo H 'INFINITO' não linear e adaptativo H 'INFINITO' não linear com redes neurais para robôs manipuladores. Também é desenvolvido um sistema tolerante a falhas para robôs manipuladores baseado em sistemas Markovianos e em controladores Markovianos H'IND.2', H 'INFINITO' e H'IND.2'/ H 'INFINITO'. Na segunda parte, o modelo dinâmico de robôs manipuladores cooperativos subatuados é representado na forma de espaço de estados, possibilitando a aplicação dos controladores H 'INFINITO' não lineares para controle de posição, juntamente com controle das forças de esmagamento, de um objeto.<br>This work presents the development, implementation and analysis of nonlinear H control techniques applied to underactuated manipulators, under parametric uncertainties and external disturbances. At the first part, two approaches are considered for underactuated individual manipulators. The first approach consists in representing manipulators as nonlinear systems in the quasi-linear parameter varying form and in controlling them via H control for linear parameter varying systems based on linear matrix inequalities. At the second approach, an explicit solution to the nonlinear H control problem for manipulators is found via differential game theory. With this procedure, it is also implemented the nonlinear mixed H2/H, nonlinear adaptive H, and nonlinear adaptive H with neural networks controls. Also is developed a fault tolerant system for manipulators based on Markovian systems and Markovian H2, H, and H2/H controls. At the second part, the dynamic model of underactuated cooperative manipulators is represented in the state space form in order to apply the nonlinear H controls to position control, plus the squeeze force control, of an object.

Abstract:

Au cours de la dernière décennie, d'énormes quantités de documents multimédias ont été générées. Il est donc important de trouver un moyen de gérer ces données, notamment d'un point de vue sémantique, ce qui nécessite une connaissance fine de leur contenu. Il existe deux familles d'approches pour ce faire, soit par l'extraction d'informations à partir du document (par ex., audio, image), soit en utilisant des données textuelles extraites du document ou de sources externes (par ex., Web). Notre travail se place dans cette seconde famille d'approches ; les informations extraites des textes peuvent ensuite être utilisées pour annoter les documents multimédias et faciliter leur gestion. L'objectif de cette thèse est donc de développer de tels modèles d'extraction d'informations. Mais les textes extraits des documents multimédias étant en général petits et bruités, ce travail veille aussi à leur nécessaire robustesse. Nous avons donc privilégié des techniques simples nécessitant peu de connaissances externes comme garantie de robustesse, en nous inspirant des travaux en recherche d'information et en analyse statistique des textes. Nous nous sommes notamment concentré sur trois tâches : l'extraction supervisée de relations entre entités, la découverte de relations, et la découverte de classes d'entités. Pour l'extraction de relations, nous proposons une approche supervisée basée sur les modèles de langues et l'algorithme d'apprentissage des k-plus-proches voisins. Les résultats expérimentaux montrent l'efficacité et la robustesse de nos modèles, dépassant les systèmes état-de-l'art tout en utilisant des informations linguistiques plus simples à obtenir. Dans la seconde tâche, nous passons à un modèle non supervisé pour découvrir les relations au lieu d'en extraire des prédéfinies. Nous modélisons ce problème comme une tâche de clustering avec une fonction de similarité là encore basée sur les modèles de langues. Les performances, évaluées sur un corpus de vidéos de matchs de football, montrnt l'intérêt de notre approche par rapport aux modèles classiques. Enfin, dans la dernière tâche, nous nous intéressons non plus aux relations mais aux entités, source d'informations essentielles dans les documents. Nous proposons une technique de clustering d'entités afin de faire émerger, sans a priori, des classes sémantiques parmi celles-ci, en adoptant une représentation nouvelle des données permettant de mieux tenir compte des chaque occurrence des entités. En guise de conclusion, nous avons montré expérimentalement que des techniques simples, exigeant peu de connaissances a priori, et utilisant des informations linguistique facilement accessibles peuvent être suffisantes pour extraire efficacement des informations précises à partir du texte. Dans notre cas, ces bons résultats sont obtenus en choisissant une représentation adaptée pour les données, basée sur une analyse statistique ou des modèles de recherche d'information. Le chemin est encore long avant d'être en mesure de traiter directement des documents multimédia, mais nous espérons que nos propositions pourront servir de tremplin pour les recherches futures dans ce domaine.

Abstract:

Parallel robots with configurable platform are a class of parallel robots in which the end-effector is a closed-loop flexible chain of rigid links. We have developed a 5-RRR planar mechanism that features a flexible 5-bar chain as end-effector. The angles between adjacent sides of this chain can be controlled through the actuated revolute joints attached to the base of the mechanism. This thesis consists in the geometrical design of n-RRR planar parallel robots and in the study of the Direct Kinematics for 4-, 5- and 6-RRR mechanisms using Bilateration, a method that greatly reduces the computational time for the kinematic analysis. The next step is the singularity analysis for the n-RRR robot architectures; finally, in the last part of this thesis we present the results from experimental tests that have been performed on a 5-RRR robot prototype.

Dans ce mémoire, je parle à une montagne, un cercle, un lichen et à un ver que l’on appelle le Bouzou. Partant d’une exploration de mon propre rapport au monde ou plus précisément à l’environnement naturel, je transforme celui-ci progressivement et propose une attitude holistique de plus en plus radicale : celle d’une tentative de rapprochement avec un organisme naturel primitif, le Bouzou. Une quête allant jusqu’à incarner la dynamique de cet élément naturel est relatée à travers nombreux petits récits personnels entrecoupés de réflexions et de citations. Tout au long de la lecture se crée du mouvement; un rythme dû aux allers-retours entre proximité et distance. J’affirme et expose progressivement dans ce mémoire qu’à travers les rapports entre les choses et leurs possibles en tant que connecteurs se révèle l’importance de la relation de l’humain avec l’environnement naturel. Ce texte accompagne l’exposition Bouzou qui sera présentée du 7 au 14 décembre 2018 dans l’espace américain de Vu Photo, Centre de diffusion et de production de la photographie. Les corpus installés dans l’espace se présentent sans hiérarchie visible, créant une structure horizontale à travers laquelle le médium photographique agit comme liant. L’exposition tente de révéler le rythme, les réflexions, les sensations, les formes et le mouvement progressif que m’a inspirés ma rencontre avec le Bouzou

Abstract:

Avec la complexification des tâches confiées aux robots, la perception de l’environnement, aussi appelée perception de scène, doit se faire de manière plus complète. L’emploi simultané de différents types de capteurs, ou multimodalité, est l’un des leviers employés à cet effet. L’exploitation de données issues de modalités différentes nécessite généralement de connaître la pose, c’est-à-dire l’orientation et la position, de chaque capteur relativement aux autres. Les travaux présentés dans cette thèse se concentrent sur la problématique d’estimation de pose robuste dans le cas d’une multimodalité incluant des capteurs de type caméra et LiDAR. Deux contributions majeures sont présentées dans ce manuscrit. On présente dans un premier temps un algorithme d’estimation de pose original s’appuyant sur la correspondances entre droites 2D et 3D, ainsi qu’une connaissance a priori de la direction verticale. Dans l’optique d’améliorer la robustesse de cet algorithme, une deuxième contribution repose sur un algorithme d’appariement de droites et de rejet de paires aberrantes basé RANSAC. Cette méthode fonctionne à l’aide de deux ou d’une seule paire de droites, diminuant le coût en calcul du problème. Les résultats obtenus sur des jeux de données simulées et réelles démontrent une amélioration des performances en comparaison avec les méthodes de l’état de l’art<br>Camera pose estimation consists in determining the position and the orientation of a camera with respect to a reference frame. In the context of mobile robotics, multimodality, i.e. the use of various sensor types, is often a requirement to solve complex tasks. However, knowing the orientation and position, i.e. the pose, of each sensor regarding a common frame is generally necessary to benefit multimodality. In this context, we present two major contributions with this PhD thesis. First, we introduce a pose estimation algorithm relying on 2D and 3D line and a known vertical direction. Secondly, we present two outliers rejection and line pairing methods based on the well known RANSAC algorithm. Our methods make use of the vertical direction to reduce the number of lines required to 2 and 1, i.e. RANSAC2 and RANSAC1. A robustness evaluation of our contributions is performed on simulated and real data. We show state of the art results
