This book was released on 1994 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: LES ARCHITECTURES SYSTOLIQUES COMMENCENT A ETRE EMPLOYEES DANS L'INDUSTRIE EN RAISON DE LEURS PROPRIETES DE REGULARITE ET DE LOCALITE QUI LES RENDENT PARTICULIEREMENT BIEN ADAPTEES A L'INTEGRATION SUR SILICIUM. LE PROCESSUS DE CONCEPTION D'UN CIRCUIT INTEGRE REQUIERT UNE PHASE DE SIMULATION FONCTIONNELLE AFIN DE TESTER ET DE VALIDER DIFFERENTES IMPLEMENTATIONS D'UN MEME ALGORITHME. COMME IL S'AGIT EN GENERAL D'ALGORITHMES TRES COUTEUX EN TEMPS DE CALCUL, LES MACHINES PARALLELES CONSTITUENT LE SEUL MOYEN DE REALISER DES SIMULATIONS REALISTES, PAR EXEMPLE EN TEMPS REEL DANS LE CAS DU TRAITEMENT DU SIGNAL. CETTE THESE DECRIT L'ENVIRONNEMENT DE PROGRAMMATION RELACS, CONCU POUR LA SIMULATION DES RESEAUX LINEAIRES SYSTOLIQUES SUR DES MACHINES PARALLELES. RELACS FOURNIT A L'UTILISATEUR UN MODELE D'EXECUTION PARALLELE, EFFICACE ET INDEPENDANT DE LA MACHINE CIBLE. CE MODELE D'EXECUTION S'APPARENTE A CELUI DE LA MACHINE MICMACS, OU PROCESSUS DE CALCUL DU RESEAU SYSTOLIQUE ET PROCESSUS DE GESTION DES ENTREES-SORTIES DU RESEAU S'EXECUTENT EN RECOUVREMENT. LA PROGRAMMATION S'EFFECTUE DANS LE LANGAGE C-STOLIC, UN LANGAGE A PARALLELISME DE DONNEES, DOTE D'OPERATEURS DE COMMUNICATION SYNCHRONES QUI REFLETENT LES MOUVEMENTS DE DONNEES INTERNES D'UN RESEAU SYSTOLIQUE ET SES ENTREES-SORTIES. PLUSIEURS APPLICATIONS, DANS LE DOMAINE DU TRAITEMENT DU SIGNAL, DU TRAITEMENT DE CHAINES DE CARACTERES, DU CALCUL NUMERIQUE ET DE LA PROGRAMMATION LINEAIRE, ONT ETE DEVELOPPEES AVEC L'ENVIRONNEMENT RELACS, VALIDANT AINSI LE CHOIX DU MODELE DE PROGRAMMATION C-STOLIC. LES PERFORMANCES OBTENUES POUR CES APPLICATIONS SUR LA MACHINE IWARP DEMONTRENT L'EFFICACITE DE NOTRE MODELE D'EXECUTION POUR LES CALCULS SYSTOLIQUES

Book excerpt: Presenting a complementary perspective to standard books on algorithms, A Guide to Algorithm Design: Paradigms, Methods, and Complexity Analysis provides a roadmap for readers to determine the difficulty of an algorithmic problem by finding an optimal solution or proving complexity results. It gives a practical treatment of algorithmic complexity and guides readers in solving algorithmic problems. Divided into three parts, the book offers a comprehensive set of problems with solutions as well as in-depth case studies that demonstrate how to assess the complexity of a new problem. Part I helps readers understand the main design principles and design efficient algorithms. Part II covers polynomial reductions from NP-complete problems and approaches that go beyond NP-completeness. Part III supplies readers with tools and techniques to evaluate problem complexity, including how to determine which instances are polynomial and which are NP-hard. Drawing on the authors’ classroom-tested material, this text takes readers step by step through the concepts and methods for analyzing algorithmic complexity. Through many problems and detailed examples, readers can investigate polynomial-time algorithms and NP-completeness and beyond.

This book was released on 2016-11-04 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: Millions of people are already affected by weather-related shocks every year in West Africa and climate change is highly likely to increase these threats. In the wake of climate change, rising temperatures, increasingly irregular rainfall and more frequent natural hazards will endanger the ways of life of vulnerable population groups in this region and destabilize their human security. A surge in violence and conflicts could take place. One of the conflict constellations could be between farmers and herders. These groups are highly vulnerable to climate change due to their dependence on natural resources Millions of people are already affected by weather-related shocks every year in West Africa and climate change is highly likely to increase these threats. In the wake of climate change, rising temperatures, increasingly irregular rainfall and more frequent natural hazards will endanger the ways of life of vulnerable population groups in this region and destabilize their human security. A surge in violence and conflicts could take place. One of the conflict constellations could be between farmers and herders. These groups are highly vulnerable to climate change due to their dependence on natural resources for their subsistence. Furthermore, they are historically prone to enter into conflict over issues of access to natural resources. However, social, economic and political circumstances fundamentally influence environmental conflicts. There might thus be opportunities to face the societal challenges of climate change in a peaceful way and the political and institutional framework could play an important role in reducing conflict and violence. In order to explore such a path, this study analyses the potential of political factors (policies and institutions) for the reduction of climate-change-induced or aggravated conflicts between farmers and herders. After a theoretical demonstration, a case study of agro-pastoral conflicts in Burkina Faso, Côte d’Ivoire, and Ghana is conducted. their subsistence.

This book was released on 2001-12-31 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: Measurement of Cardiac Deformations from MRI: Physical and Mathematical Models describes the latest imaging and imag analysis techniques that have been developed at leading centers for the visualization, analysis, and understanding of normal and abnormal cardiac motion with magnetic resonance imaging (MRI). The use of MRI in measuring cardiac motion is particularly important because MRI is non-invasive, and it is the only modality capable of imaging detailed intramural motion within the myocardium. Biomedical engineers, medical physicists, computer scientists, and physicians interested in learning about the latest advances in cardiovascular MRI should find this book to be a valuable educational resource. In particular, it is more tutorial in nature than most of the technical papers where the research was originally published. Practitioners and researchers working in the field of cardiovascular MRI will find the book to be filled with practical technical details and references to other work, enabling the implementation of existing methods and serving as a basis for further research in the area.
