Book excerpt: Les techniques mathématiques de reconstruction d'image jouent un rôle important dans le domaine médical. Elles permettent d'exploiter, par résolution d'un problème inverse, les mesures issues d'appareils médicaux comme le scanner pour obtenir une image volumique représentant la répartition spatiale d'une propriété, comme la densité des tissus. Les progrès des scanners rendent désormais possible l'étude dynamique de certains organes, comme le coeur. Cependant, les techniques de reconstruction classiques doivent être améliorées pour prendre en compte les évolutions des organes durant l'acquisition des mesures, qui provoquent une perte de qualité et donc d'information dans les images reconstruites. L'objectif de ce travail de thèse est d'investiguer l'usage de modèles additionnels permettant de régulariser le problème de reconstruction tomographique. Dans une première étude, nous approfondissons les méthodes couramment utilisées en tomographie cardiaque basées sur l'utilisation d'un modèle de périodicité de l'évolution. Nous étudions les problèmes de synchronisation dans les géométries parallèles et divergentes et leur lien avec l'échantillonnage des mesures. Nous proposons par ailleurs un schéma de reconstruction amélioré dans le cas des géométries divergentes. La seconde étude concerne les méthodes dites de compensation du mouvement, qui utilisent dans l'algorithme de reconstruction un modèle de déformation de la scène connu a priori. Nous proposons des méthodes analytiques de reconstruction qui compensent les déformations affines dépendant du temps, en établissant des conditions d'admissibilité et des formules d'inversion exactes.

Available in PDF, EPUB and Kindle. Book excerpt: In geophysics, tomography is a technique which deduces some physical properties of the medium from the perturbations encountered by waves propagating through it. Thus tomography draws on a variety of disciplines, such as wave propagation in heterogeneous media, statistical estimation and inverse theory, and numerical modeling. These subjects take different forms when applied to solid Earth geophysics or to physical oceanography. The aim of the 50th session of the Les Houches Summer School was to present in detail theoretical and practical aspects of tomography in geophysics and oceanography. One of the goals was to bring together students and practitioners of the two fields to teach, discuss and exchange ideas on all the components of tomography, to point out common approaches and to contrast various specific applications. The resulting book shows the diversity and vitality of this field of research and underlines the variety of disciplines involved.

This book was released on 2008-06-19 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: In engineering design and development, reliable and accurate computational methods are requested to replace or complement expensive and time consuming experimental trial and error work. Tremendous advancements have been achieved during recent years due to improved numerical solutions of non-linear partial differential equations and computer developments to achieve efficient and rapid calculations. Nevertheless, to further progress in computational methods will require developments in theoretical and predictive procedures – both basic and innovative – and in applied research. Accurate experimental investigations are needed to validate the numerical calculations. This book contains the edited versions of the papers presented at the Tenth International Conference on Advanced Computational Methods and Experimental Measurements in Heat Transfer and Mass Transfer held in Maribor, Slovenia in July 2008. The objective of this conference series is to provide a forum for presentation and discussion of advanced topics, new approaches and application of advanced computational methods and experimental measurements to heat and mass transfer problems. The contributed papers are grouped in the following appropriate sections to provide better access for readers: Natural and forced convection; Heat exchangers; Advances in computational methods; Heat recovery; Heat transfer; Modelling and experiments.

Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS)* at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dis semination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volumes were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 39 (thesis year 1994) a total of 13,953 thesis titles from 21 Canadian and 159 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this impor tant annual reference work. While Volume 39 reports theses submitted in 1994, on occasion, certain uni versities do report theses submitted in previous years but not reported at the time.

This book was released on 2003 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first clinical book on the hottest topic in radiation oncology, this timely teaching text offers step-by-step guidance in use of IMRT for cancers at each subsite of the head and neck. The book's high-end content gives readers the clinical decision-making expertise and technical proficiency to incorporate this state-of-the-art radiation treatment technique into practice. Unique to this text is the site-specific instruction on target determination and delineation, to ensure adequate treatment of the tumor target while sparing adjacent normal tissue. More than 250 detailed full-color and black-and-white illustrations clarify each step in clinical implementations of head and neck cancer treatment, especially IMRT. The book provides a concise, pertinent overview of the natural course, lymph node spread, diagnostic criteria, and therapeutic options for each head and neck cancer subsite. Numerous tables provide extensive summaries of the IMRT literature. Figures with succinct explanatory text demonstrate the patterns of direct tumor extension and nodal metastasis with which target volumes are determined and delineated. Clinical outcomes for patients treated with IMRT and with conventional techniques are also included.
