L'IRMd est un moyen non invasif permettant d'étudier in vivo la structure des fibres nerveuses du cerveau. Dans cette thèse, nous modélisons des données IRMd à l'aide de tenseurs d'ordre 4 (T4). Les problèmes de comparaison de groupes ou d'individu avec un groupe normal sont abordés, et résolus à l'aide d'analyses statistiques sur les T4s. Les approches utilisent des réductions non linéaires de dimension, et bénéficient des métriques non euclidiennes pour les T4s. Les statistiques sont calculées dans l'espace réduit, et permettent de quantifier la dissimilarité entre le groupe (ou l'individu) d'intérêt et le groupe de référence. Les approches proposées sont appliquées à la neuromyélite optique et aux patients atteints de locked in syndrome. Les conclusions tirées sont cohérentes avec les connaissances médicales actuelles. / DW-MRI is a non-invasive way to study in vivo the structure of nerve fibers in the brain. In this thesis, fourth order tensors (T4) were used to model DW-MRI data. In addition, the problems of group comparison or individual against a normal group were discussed and solved using statistical analysis on T4s. The approaches use nonlinear dimensional reductions, assisted by non-Euclidean metrics for T4s. The statistics are calculated in the reduced space and allow us to quantify the dissimilarity between the group (or the individual) of interest and the reference group. The proposed approaches are applied to neuromyelitis optica and patients with locked in syndrome. The derived conclusions are consistent with the current medical knowledge.

The aim of this thesis is a complex design of the spotting press with a nominal force of 500 kN, which is intended for mating of the both halves of pressing tool for the automotive industry. The press ram is fitted with a hydraulic mechanism which allows the upper clamping board to be tilted in range of 0° -180° and removed from the working space of the press along a profile track. The lower clamping board is a part of moving bolster, which is equipped with a mechanism for lifting and centring. The concept of motion screws is used to drive the ram. Motion screws are mounted in a multiple-part frame and driven by servomotors. The thesis contains background research of the issue, solutions of the main design nodes of the press including calculations, detailed 3D model of the device and partial drawing documentation.

This Master thesis deals with design structures of moving bolster for body panel press and with design of railroad tracks, in which the bolster is moving in two mutually perpendicular directions. These moving bolsters are used for facilitating and speeding up the change of pressing dies, which is desirable in automated automotive industry for shortening and streamlining the pressing die change. The part of the work is research of the current state of knowledge in systems for quick die change, design of the moving bolster and its drive, design of railroad tracks, amount of design and control calculations, design of mechanism for lifting the bolster, optimization and strength calculations of bolster in ANSYS software. All the design structures of bolster, railroad tracks and basic workplace layout are processed in 3D software for modelling Autodesk Inventor. Attachments consist of drawing documentation of main assemblies, namely mounting drawing of moving bolster assembly, mounting drawing of railroad tracks assembly, drawing of workplace layout and furthermore drawing of driven shaft, weldment and workpiece of moving bolster and railroad tracks block.

The aim of this study is to analyse mutual enactments of critical literacies and social visualisation tools as information resources. The central concept of critical literacies as used here extends and redefines prior critical literacy definitions to denote the pluralistic situated enactments of meaning through which study participants identify, question and transform bias, restrictions and power related aspects of access, control and use in relation to the tools. The study is based on two critical ethnography inspired case studies involving observations, interviews, and contextual inquiry and located in professional settings. Case 1 is centred on how a geographic information system (MapInfo) is used for analysing and preventing traffic accidents. Case 2 is centred on how a dynamic time series animating chart (Trendalyzer) is used for analysing and spreading knowledge about the world’s development. The results demonstrate co-existing critical literacies described in terms of three main directionalities as reactive, proactive, and adaptive, of which the adaptive varieties seem thus far largely overlooked. On the basis of these findings, it is suggested that dominant cognitivist and positivist narratives of visualisations should be replaced with more nuanced alternatives that emphasise the potentials of visualisation tools as evocative and non-blackboxed information resources; i.e., as encouraging new questions and allowing alternative analyses, rather than constructing them as enunciative tools providing true answers. As theoretical contributions, the dissertation argues for a conceptualisation of visualisation tools as representational artefacts and a species of documents actuating information organisation related problems of representation. It also presents a new theoretical construct for the analysis and understanding of the mutual shaping of critical literacies and information resources that includes both cultural practices and actor interests through a combination of sociocultural theories on tools and sociotechnical theories on inscriptions. / <p>Academic dissertation for the Degree of Doctor of Philosophy in Library and</p><p>Information Science at the University of Borås to be publicly defended on Friday</p><p>14 December 2012 at 13.00 in lecture room C203, the University of Borås,</p><p>Allégatan 1, Borås.</p>

Le criocère du lis, Lilioceris lilii (Coleoptera : Chrysomelidae), un ravageur de lis et de fritillaires d’origine eurasienne, a été observé pour la première fois en Amérique du Nord en 1943 sur l’Ile de Montréal au Canada. Après y avoir été confiné pendant environ 25 années, ce coléoptère a par la suite progressé rapidement sur le territoire nord-américain. Actuellement, on l’observe dans huit provinces canadiennes et huit états américains. Cette étude a investigué les routes d’invasion utilisées par le criocère du lis au Canada et aux États- Unis avec l’aide de marqueurs génétiques AFLP. Pour ce faire, 516 individus parmi 34 sites en Amérique du Nord et en Europe ont été échantillonnés et analysés. Le premier objectif était de déterminer, en analysant la structure génétique des populations nord-américains, s’il y avait eu une ou plusieurs introductions en provenance d’Europe. Le deuxième objectif était d’identifier l’origine de la ou des populations introduites en Amérique du Nord. Finalement, le troisième objectif consistait à proposer un scénario d’invasion de L. lilii en Amérique du Nord basé sur les données de première mention et de structure génétique des populations échantillonnées. Les résultats démontrent une signature génétique distincte entre les criocères du lis du Canada et ceux des États-Unis, suggérant ainsi deux sources d’introductions indépendantes en Amérique du Nord, soit une première introduction à Montréal, Québec, dans les années 1940 et une seconde aux États-Unis au début des années 1990 à Cambridge, Massachusetts. De plus, les deux populations nord-américaines semblent provenir de différentes régions du nord de l’Europe, ce qui est conséquent avec le scénario suggérant deux sources d’introductions indépendantes. Chacune des populations aurait par la suite progressé respectivement dans leur pays d’introduction selon une dispersion de type stratifiée. En effet, la progression continue de L. lilii dans certaines régions suggère une dispersion naturelle de l’espèce sur le territoire nord-américain, alors que la progression rapide sur de longues distances semble être causée par le transport anthropique de lis contaminés. / The lily leaf beetle, Lilioceris lilii (Coleoptera : Chrysomelidae), a Eurasian pest of lilies and fritillaries, was first observed in North America in 1943 on the Island of Montréal, Canada. After being confined to Montréal for approximately 25 years, the beetle quickly progressed in North America, and is currently present in eight Canadian provinces and eight American states. During this study, we have investigated the routes of invasion followed by L. lilii in North America, using AFLP markers. We sampled and analysed 516 individuals from 34 sites across North America and Europe. Our first objective was to characterize the genetic structure of North American L. lilii populations to determine if they originated from a single or form multiple introductions from Europe. The second objective was to identify the geographical origin of the invasive population(s). Finally, the third objective was to trace back the geographical routes of invasion of L. lilii in North America, using information from both the dates of first observations and the genetic structure of sampled populations. Our results showed clear genetic difference between individuals from Canada and the USA, suggesting at least two different sources of introductions of L. lilii in North America. A first episode of introduction took place in Montréal, Canada in the 1940’s while a second introduction occurred in Cambridge, Massachusetts, around 1990. Also, both North American populations seem to originate from different populations in northern Europe, which support the hypothesis of two distinct sources of introduction. Each population next progressed in its respective country following a stratified dispersal. Indeed, continuous progression of the beetle in some regions of North America suggests a pattern of natural dispersion, while human-mediated carrying of infected lilies seemed to be responsible for the long-range movement of the beetle.

L’essor théorique de l’arbitrage international observé dans les dernières décennies n’a pas toujours été accompagné par le développement d’instruments d’application de ses représentations conceptuelles. L’idée d’un ordre juridique arbitral détaché des ordres étatiques est défendue dans un souci de systématisation théorique du problème plutôt que de résolution pratique du litige entre les parties. En même temps, la justice choisit de s’intéresser plutôt à la solution de l’ordre qu’à celle de l’équité. Nous proposons alors d’examiner les principales distorsions résultant de l’intervention étatique dans l’arbitrage international à partir de cette perspective, soit-elles relatives à la convention (comme les mesures provisoires et référés étatiques ou les contestations de la clause compromissoire), soit-elles relatives à la sentence, spécialement autour de l’exequatur des sentences annulées. Nous présentons la litispendance, les anti-suit injunctions, la res judicata et les tentatives de dialogue entre les différents fors comme des instruments aptes au contrôle de ses déviances, lesquels sont encore trop limités par un raisonnement d’application généralisant, déductif et amoral, fondé sur la méthode du droit international privé, qui n’a plus sa place dans l’arbitrage international. Face à ces distorsions, nous proposons alors la doctrine de l’abus de droit pour permettre un retour vers l’intérêt des parties dans l’arbitrage international. Sans négliger l’importance du « droit », correspondant aux représentations théoriques de l’arbitrage international, cette notion peut néanmoins en saisir les « abus ». La doctrine de l’abus apporte alors une conception matérielle, flexible et finaliste aux mécanismes de contrôle de l’arbitrage international. On ne parlera alors plus de distorsions de l’ordre juridique arbitral, mais d’abus de l’ordre juridique arbitral. / The academic success of international arbitration in the last decades has not always been followed by the consequent development of concrete instrument for its practical applications. The concept of an arbitral legal order detached from national legal systems is defended by doctrine not so much as an useful instrument for practical case resolution, but firstly as a problem of raising a logic and coherent legal scheme. We propose to analyze the main distortions caused by the conflict between this theoretical perspective of an autonomous legal order and the practical matters involved in the pragmatic courts intervention in international arbitration, either relating to the arbitral convention (provisional measures, violation of the arbitration clause) or to the arbitral award, specifically regarding the problem of recognizing annulled awards. We present lis pendens, anti-suit injunctions, res judicata and the efforts of dialogue between jurisdictions judging the sentence regularity as the main instruments contributing to a dialogue, and thus, as instruments to control its possible distortions. However, those mechanisms are deployed through a reasoning that is still too generic, amoral and based in principles of private international law, in a state-centered perspective that cannot serve the international arbitration scheme today. From this finding, we suggest the abuse of rights doctrine as a group of different objectives and subjective standards allowing implementing those mechanisms to control international arbitration in a much more appropriate way, considering its autonomous and material characteristics, embodied in the doctrinal pursuit of an arbitral legal order. This doctrine brings a more flexible, material and finalistic perspective to the international arbitration instruments, approaching the parties interests and leaving a purely conflictual method which is not anymore appropriate in this field. There will be not anymore only distortions of an arbitral legal order, but abuses of that same arbitral legal order.
