This book was released on 1996 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: Le but de cette thèse est d'étudier l'adéquation des approches parallèles à l'imagerie 3D, en prenant comme problème cible de la reconstruction d'images 3D en tomographie par rayons X. L'évolution technologique des systèmes d'acquisition, du premier scanner au Morphomètre, a généré de nouvelles problématiques au niveau des méthodes de reconstruction et au niveau des besoins informatiques. Une première partie est consacrée aux fondements de la tomographie assistée par ordinateur et à la présentation des machines parallèles. L'évolution des machines de calcul intensif, du Cray 1 au Cray T3D, permet de résoudre des problèmes de taille croissante. Dans la deuxième partie, nous définissons la méthodologie suivie pour paralléliser les algorithmes de reconstruction. Nous identifions les opérateurs de base (projection et rétroprojection) sur lesquel est porté l'effort de parallélisation. Nous définissons deux approches de parallélisation (locale et globale). Différentes versions optimisées de ces algorithmes parallèles sont présentées prenant en compte d'une part la minimisation des temps de communications (recouvrement calcul/communication, communication sur un arbre binaire) et d'autre part la régulation de charge (partitionnement adaptatif). Dans la troisième partie, à partir de ces opérateurs parallélisés, nous construisons trois méthodes de reconstruction parallèles : une méthode analytique (la méthode de Feldkamp) et deux méthodes algébriques (la méthode Art par blocs et méthode SIRT). Les algorithmes sont expérimentés sur différentes machines parallèles : Maspar, Réseau de stations Sun, Ferme de processeurs Alpha, Paragon d'Intel, IBM SP1 et Cray T3D. Pour assurer la portabilité sur les différentes machines, nous avons utilisé PVM. Nous évaluons nos performances et nous montrons nos résultats de reconstruction 3D à partir de données simulées. Puis, nous présentons des reconstructions 3D effectués sur le Cray T3D, à partir de données expérimentales du Morphomètre, prototype de scanner X 3D

Book Synopsis Space, Structure and Randomness by : Michel Bilodeau
Download or read book Space, Structure and Randomness written by Michel Bilodeau and published by Springer Science & Business Media. This book was released on 2007-12-23 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: Space, structure, and randomness: these are the three key concepts underlying Georges Matheron’s scientific work. He first encountered them at the beginning of his career when working as a mining engineer, and then they resurfaced in fields ranging from meteorology to microscopy. What could these radically different types of applications possibly have in common? First, in each one only a single realisation of the phenomenon is available for study, but its features repeat themselves in space; second, the sampling pattern is rarely regular, and finally there are problems of change of scale. This volume is divided in three sections on random sets, geostatistics and mathematical morphology. They reflect his professional interests and his search for underlying unity. Some readers may be surprised to find theoretical chapters mixed with applied ones. We have done this deliberately. GM always considered that the distinction between the theory and practice was purely academic. When GM tackled practical problems, he used his skill as a physicist to extract the salient features and to select variables which could be measured meaningfully and whose values could be estimated from the available data. Then he used his outstanding ability as a mathematician to solve the problems neatly and efficiently. It was his capacity to combine a physicist’s intuition with a mathematician’s analytical skills that allowed him to produce new and innovative solutions to difficult problems. The book should appeal to graduate students and researchers working in mathematics, probability, statistics, physics, spatial data analysis, and image analysis. In addition it will be of interest to those who enjoy discovering links between scientific disciplines that seem unrelated at first glance. In writing the book the contributors have tried to put GM’s ideas into perspective. During his working life, GM was a genuinely creative scientist. He developed innovative concepts whose usefulness goes far beyond the confines of the discipline for which they were originally designed. This is why his work remains as pertinent today as it was when it was first written.

Book Synopsis Railway Noise and Vibration by : David Thompson
Download or read book Railway Noise and Vibration written by David Thompson and published by Elsevier. This book was released on 2008-12-11 with total page 535 pages. Available in PDF, EPUB and Kindle. Book excerpt: Railways are an environmentally friendly means of transport well suited to modern society. However, noise and vibration are key obstacles to further development of the railway networks for high-speed intercity traffic, for freight and for suburban metros and light-rail. All too often noise problems are dealt with inefficiently due to lack of understanding of the problem. This book brings together coverage of the theory of railway noise and vibration with practical applications of noise control technology at source to solve noise and vibration problems from railways. Each source of noise and vibration is described in a systematic way: rolling noise, curve squeal, bridge noise, aerodynamic noise, ground vibration and ground-borne noise, and vehicle interior noise. - Theoretical modelling approaches are introduced for each source in a tutorial fashion - Practical applications of noise control technology are presented using the theoretical models - Extensive examples of application to noise reduction techniques are included Railway Noise and Vibration is a hard-working reference and will be invaluable to all who have to deal with noise and vibration from railways, whether working in the industry or in consultancy or academic research. David Thompson is Professor of Railway Noise and Vibration at the Institute of Sound and Vibration Research, University of Southampton. He has worked in the field of railway noise since 1980, with British Rail Research in Derby, UK, and TNO Institute of Applied Physics in the Netherlands before moving to Southampton in 1996. He was responsible for developing the TWINS software for predicting rolling noise. - Discusses fully the theoretical background and practical workings of railway noise - Includes the latest research findings, brought together in one place - Forms an extended case study in the application of noise control techniques
