Book excerpt: L'objet de cette thèse est l'étude de la parallélisation d'algorithmes du calcul scientifique et leur implémentation sur des ordinateurs parallèles à mémoire partagée et sur des réseaux systoliques. Un accent particulier est mis sur l'obtention de résultats de complexité. La thèse est organisée autour d'articles et textes de conférences qui sont analysés et discutés dans une première partie de façon à permettre de replacer les problèmes traités dans leur contexte. Dans le premier chapitre, nous présentons les principaux résultats théoriques concernant l'étude de complexité des algorithmes parallèles, ainsi qu'une description critique de l'architecture de référence, qui est une machine de type MIMD à mémoire partagée. Le chapitre suivant est dédie" à l'ensemble des résultats de complexité concernant les algorithmes de diagonalisation et l'élimination de Gauss, il a pour but d'illustrer la méthodologie. Il existe en tout dix écritures possibles de la méthode de Gauss, qui conduisent principalement à deux grandes classes de graphes de précédente, conceptuellement différents : les graphes de type "glouton" et ceux du type "2 pas". Ces types de graphes se rencontrent d'une manière plus générale dans d'autres problèmes d'algèbre linéaire et même dans certaines méthodes non numériques de la théorie des graphes. Nous développons les résultats de complexité concernant ces deux types de graphes sur les exemples les plus courant (versions kji et kij de Gauss en parallèle), puis nous montrons comment adapter l'étude en prenant en compte t'es temps de communication entre tes processeurs, ce qui rend le modèle théorique plus réaliste. Le chapitre 6 est consacré aux architectures systoliques. Le problème du chemin algébrique permet d'unifier plusieurs problèmes informatiques. Nous présentons un réseau résolvant ce problème en Sn-2 pas sur un réseau de taille n(n+l ). De plus, quelques modifications permettent de calculer des projections en filtrage adaptatif en vu d'obtenir une solution en temps réel pour le traitement numérique des signaux. Avant de conclure, nous présentons des résultats complémentaires de parallélisation effective sur d'autres types d'architectures : l'étude de l'algorithme du gradient conjugué sur des super calculateurs (CRAY-XMP et IBM 3090-VF).

Available in PDF, EPUB and Kindle. Book excerpt: Les travaux présentés dans cette thèse portent sur les difficultés algorithmiques soulevées par l'introduction de l'hétérogénéité des plates-formes modernes dans le calcul parallèle et distribué. Les contributions de cette thèse se situent à trois niveaux : 1) Algorithmique Parallèle : distributions hétérogènes pour les noyaux d'algèbre linéaire denses (produit de matrice, décomposition LU), technique de rééquilibrage, légère et efficace en cas de petites variations de charge des processeurs ; 2) Modélisation et simulation : l'instabilité latente des plates-formes de calcul distribuées à grande échelle interdit toute validation expérimentale grandeur nature d'un algorithme ou d'une politique d'ordonnancement. Nous avons proposé des modèles simples et un simulateur réaliste pour palier ce problème; 3) Ordonnancement : un certain nombre d'applications sont constituées d'un grand nombre de tâches indépendantes et de caractéristiques identiques. Nous avons établi des résultats de complexité et proposé des approximations pour différentes modélisation de ce problème.

Book Synopsis Decoding Cardiac Electrophysiology by : Afzal Sohaib
Download or read book Decoding Cardiac Electrophysiology written by Afzal Sohaib and published by Springer Nature. This book was released on 2019-11-09 with total page 109 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a concise overview of cardiac electrophysiology for cardiologists who are not electrophysiologists and for allied cardiovascular professionals, cardiology registrars and fellows who are new to the field. It familiarises them with the main procedures performed in the electrophysiology laboratory. Emphasis is placed on helping the reader develop a core understanding of how data is collected and interpreted in the electrophysiology laboratory, and how this is used to guide ablation for the commonest arrhythmias including AV nodal re-entry tachycardia, accessory pathways, atrial fibrillation and ventricular arrhythmias. Decoding Cardiac Electrophysiology: Understanding the Techniques and Defining the Jargon will translate some of the technical terminology and data frequently used by electrophysiologists into terms and concepts familiar to the wider cardiovascular community. This includes the interpretation of electrograms and 3D electro-anatomical maps of common arrhythmias. Accordingly, it offers a valuable resource for all non-electrophysiologists seeking a guide to the topic and for electrophysiology trainees establishing their core knowledge and skills in the field. The aim is that this should be the first book anyone new to the field should choose to read.

Book Synopsis The Geometric Supposer by : Judah L. Schwartz
Download or read book The Geometric Supposer written by Judah L. Schwartz and published by Routledge. This book was released on 2013-06-17 with total page 267 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is a case study of education reform and innovation using technology that examines the issue from a wide variety of perspectives. It brings together the views and experiences of software designers, curriculum writers, teachers and students, researchers and administrators. Thus, it stands in contrast to other analyses of innovation that tend to look through the particular prisms of research, classroom practice, or software design. The Geometric Supposer encourages a belief in a better tomorrow for schools. On its surface, the Geometric Supposer provides the means for radically altering the way in which geometry is taught and the quality of learning that can be achieved. At a deeper level, however, it suggests a powerful metaphor for improving education that can be played out in many different instructional contexts.
Download or read book Simplexity written by Alain Berthoz and published by Odile Jacob. This book was released on 2018-12-20 with total page 187 pages. Available in PDF, EPUB and Kindle. Book excerpt: “Simplexity, as I understand it, is the range of solutions living organisms have found, despite the complexity of natural processes, to enable the brain to prepare an action and plan for the consequences of it. These solutions are simplifying principles that enable the processing of information or situations, by taking into account past experience and anticipating the future. They are neither caricatures, shortcuts, or summaries. They are new ways of asking questions, sometimes at the cost of occasional detours, in order to achieve faster, more elegant, more effective actions.” A. B. As Alain Berthoz demonstrates in this profoundly original book, simplicity is never easy; it requires suppressing, selecting, connecting, thinking, in order to then act in the best way possible. And what if we, in turn, are inspired by the living world to process the complexity that surrounds us? Alain Berthoz is professor at the Collège de France where he is co-director of the Laboratoire de physiologie de la perception et de l’action. [Laboratory for the physiology of perception and action]. He is a member of the French Academy of Sciences, and is the author of Le Sens du mouvement [The Brain's Sense of Movement] and La Décision [Emotion and Reason].
Book Synopsis Mathematical Problem Solving by : Frank K. Lester
Download or read book Mathematical Problem Solving written by Frank K. Lester and published by . This book was released on 1982 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: This set of papers was originally developed for a conference on Issues and Directions in Mathematics Problem Solving Research held at Indiana University in May 1981. The purpose is to contribute to the clear formulation of the key issues in mathematical problem-solving research by presenting the ideas of actively involved researchers. An introduction provides an overview of each paper. The papers focus on the psychology of mathematical problem solving (R. E. Mayer), knowledge organization (E. A. Silver), implications from information-processing psychology, (D. J. Briars) building bridges between psychological and mathematics education research (F. K. Lester, Jr.), measuring problem solving outcomes (G. A. Goldin), a model for elementary teacher training in problem solving (J. F. LeBlanc), applied problem solving (R. Lesh, and M. Akerstrom), a concept-learning perspective (R. J. Shumway), and a statement of issues (H. L. Schoen). (MNS)

Book excerpt: "Simon Denny's new body of work for Portikus ranks among the most ambitious the artist has developed to date. Over the period of one year, the artist researched and developed an intricate project that has grown to considerable dimensions -- both physically and in terms of its critical content. For two months, the monumental gallery space is turned into an homage to technology, communication, and the relentless need for innovation. Simon Denny has produced an embracing and multi-faceted installation that functions as a documentary of the South Korean technology giant Samsung and its global success story. The exhibition's title, "New Management", refers to the legendary management philosophy that Lee Kun-hee, Chairman of the Samsung Group, infamously introduced in the early nineties."--Publisher's website.

Book Synopsis Introduction to Clinical Examination by : Michael J. Ford
Download or read book Introduction to Clinical Examination written by Michael J. Ford and published by Elsevier Health Sciences. This book was released on 2005-01-01 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: The most important core skills for medical students to master are history taking and clinical examination. This extensively revised, eighth edition has been written with the philosophy that the acquisition of clinical skills is most effectively undertaken at the bedside. This pocketbook should be used as a companion, to be taken onto the wards and into consulting rooms where the information is most needed. The book begins with a system of history taking followed by a new chapter on the analysis of key symptoms. The remaining chapters cover physical examination of each of the major systems. Each stage of the examination starts with a detailed, step-by-step description of the examination method complemented by relevant illustrations, diagrams and tables on the facing page. This book is intended primarily for use at the outset of clinical training; once students have achieved proficiency in the basic skills of interviewing and examining, the book should also prove useful for revision. An invaluable starter book concentrating purely on the fundamentals of performing a patient examination. Covers each body system and outlines the principles of: - taking a history - how to conduct a physical examination - specific examination points as appropriate Concentrates only on the main symptoms of disease and then the normal and abnormal physical findings. Mention of specific diseases is confined to those most commonly encountered. Compact and pocket-sized to be carried around easily. · Now in full colour double-page format · Clear simple colour line drawings covering the essentials of a clinical examination. · Published simultaneously with the Eleventh Edition of Macleod's Clinical Examination
