Available in PDF, EPUB and Kindle. Book excerpt: La croissance de l'utilisation de l'automobile dans le monde motive la recherche dans quatre axes principaux : l'aide à la conduite, la sécurité, le confort ou encore, l'optimisation de la consommation d'énergie et la protection de l'environnement. Dans cette thèse, nous nous intéressons plus au premier et deuxième axe. En effet, l'erreur humaine est parmi les causes principales des accidents. Les véhicules automobiles possèdent de plus en plus de systèmes d'aide à la conduite (ESP, ABS, AFU, ACC, REF, ...), permettant d'assister le conducteur dans ces actions et ainsi assurer la sécurité et réduire le nombre d'accidents. La recherche dans ce domaine reste un challenge, dans les situations de conduite critiques, ces systèmes restent à optimiser. Nous proposons dans cette thèse des lois de commande robustes pour le véhicule en se basant sur l'approche de Lyapunov, les observateurs d'état et les techniques de placement de pôles. L'outil d'optimisation convexe LMI est utilisé pour résoudre les contraintes de commande. Dans le but de commander le véhicule, nous avons développé un modèle non linéaire à onze degrés de liberté. Ce modèle est ensuite approximé par un système flou de type T-S avec incertitudes paramétriques résultants des erreurs de modélisation ou des non-linéarités du véhicule (contact pneu/sol, variations brusques de la vitesse, ...). Les outils d'analyse robustes utilisés dans cette thèse visent à calculer un correcteur robuste à ces variations, qui peuvent apparaître dans le système lui-même ou au niveau des actionneurs. Dans le but de valider les résultats de modélisation obtenus en théorie et en simulation, nous avons utilisé le logiciel de simulation de la dynamique du véhicule " veDYNA ". Nous avons aussi effectué des essais dynamiques sur piste avec un véhicule équipé d'un calculateur ESP/ABS ainsi que d'une centrale inertielle. Les données mesurées sont ensuite comparées aux résultats de simulations et montrent la validité du modèle développé.

Download or read book The Geometry of Multiple Images written by Olivier Faugeras and published by MIT Press. This book was released on 2001 with total page 682 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book formalizes and analyzes the relations between multiple views of a scene from the perspective of various types of geometries. A key feature is that it considers Euclidean and affine geometries as special cases of projective geometry. Over the last forty years, researchers have made great strides in elucidating the laws of image formation, processing, and understanding by animals, humans, and machines. This book describes the state of knowledge in one subarea of vision, the geometric laws that relate different views of a scene. Geometry, one of the oldest branches of mathematics, is the natural language for describing three-dimensional shapes and spatial relations. Projective geometry, the geometry that best models image formation, provides a unified framework for thinking about many geometric problems are relevant to vision. The book formalizes and analyzes the relations between multiple views of a scene from the perspective of various types of geometries. A key feature is that it considers Euclidean and affine geometries as special cases of projective geometry. Images play a prominent role in computer communications. Producers and users of images, in particular three-dimensional images, require a framework for stating and solving problems. The book offers a number of conceptual tools and theoretical results useful for the design of machine vision algorithms. It also illustrates these tools and results with many examples of real applications.

Download or read book The London Underground and the public private partnership agreements written by Great Britain: Parliament: House of Commons: Transport Committee and published by The Stationery Office. This book was released on 2008-01-25 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report from the Transport Committee, examines London Underground and the Public-Private Partnership Agreements. The Government originally announced proposals for modernising the London Underground network system via Public-Private Partnership (PPP) agreements in 1998. Three contracts were drawn up with: (i) Tube Lines for the maintenance and renewal of the Jubilee, Piccadilly and Northern Lines; (ii) with Metronet Rail BVC for the maintenance and renewal of the Bakerloo, Central, Victoria & Waterloo & City Lines; (iii) with Metronet Rail SSL, responsible for the maintenance and renewal of the "sub-surface lines": the Circle, District, Hammersmith & City, Metropolitan & East London Lines. These PPP Agreements, 30 years in duration, were arrangements to maintain, renew and upgrade parts of London Underground by private sector infrastructure companies (Infracos), whilst London Underground is responsible for services to customers. The PPP Agreements also set out a performance-related incentive and penalty scheme to remunerate the Infracos for the improvements they make to the network. In May 2007, Metronet admitted an overspend of £1 billion and was refused access to loan facilities by the banks. It then made a reference to the PPP Arbiter, which in turn triggered an Extraordinary Review (which occurs when extra costs are incurred above the level allowed for the bid). Metronet put in a bid for £551m but the PPP Arbiter provisionally concluded that a sum of £121m was appropriate. Metronet subsequently went into administration on 18 July 2007. The report sets out a number of conclusions and recommendations, including: contracts that were supposed to deliver 35 station upgrades, in fact delivered only 14, 40% of the requirement; stations that were supposed to cost Metronet SSL £2m, cost £7.5m, with only 65% of schedule track renewal accomplished; the Committee criticises the consequences of the imposition of PPP on Transport for London, as a "lamentable state of affairs", with the future of most of London Underground's upgrade and maintenance work in doubt; the Committee states, that the Government should remember the failure of Metronet before it considers entering similar arrangements; that the Government should publish a candid analysis of the events preceding Metronet's collapse and its consequences; the Committee believe that the PPP model was flawed and probably inferior to traditional public-sector management; that the Government needs to prioritise transparency and clarity to taxpayers and ensure that any future contracts result in clear accountability.

Book excerpt: Connected objects today present a range of opportunities in medicine. We live in a new digital era where the monitoring and analysis of one's own health information no longer belongs solely to the realm of science fiction. The success of these new devices resides in their usage, which integrates seamlessly into the daily life of the user in order to continually collect the maximum amount of data. These medical connected devices therefore constitute a new hope in transforming user experience as well as the care pathway. They offer a better level of support and a better quality of life for those suffering from chronic illnesses or mental, sensorial or physical disabilities. However, these solutions also pose systematic problems, especially regarding the risks linked to their usage. This book presents a cartography which clearly details all the potential risk scenarios linked to the usage of connected devices as well as the actions which should be undertaken to promote balanced governance and guarantee the development of high-quality medical devices. - Aims to help the reader understand the difference between a connected object and a medical connected device - Identifies and evaluates all the potential risks and perspectives associated with the use of connected medical devices - Shows how to make a comprehensive risk analysis with standards like ISO 31000 and 14971
