Available in PDF, EPUB and Kindle. Book excerpt: L'objectif de cette these est d'evaluer la capacite d'une methode particulaire inspiree des methodes Vortex-In-Cell a simuler les ecoulements de la dynamique des gaz, et plus particulierement les ecoulements multifluides. Dans un premier temps nous developpons une methode particules-grille avec remaillage pour les ecoulements compressibles non-visqueux. Le remaillage, conservatif, est realise avec des fonctions d'interpolation d'ordre eleve. Nous analysons theoriquement et testons numeriquement cette methode. Nous mettons notamment en evidence des liens forts entre notre methode et des schemas aux differences finies d'ordre eleve, de type Lax-Wendroff, et nous proposons un nouveau schema d'advection des particules, simple et plus precis. Puis nous implantons une technique multi-niveaux inspiree de l'AMR. Enfin, nous discretisons une technique de type level-set sur les particules afin de simuler l'interface entre fluides. Nous utilisons la technique multi-niveaux pour resoudre plus precisement l'interface et d'ameliorer la conservation des masses partielles.

Book excerpt: LE BUT DE CETTE THESE A CONSISTE A ETUDIER NUMERIQUEMENT ET THEORIQUEMENT DES METHODES PARTICULAIRES DETERMINISTES APPLIQUEES TOUT D'ABORD A LA CINETIQUE DES GAZ PUIS AU TRANSPORT DE CHARGES DANS DES CHAMPS ELECTROMAGNETIQUES. ON S'EST INTERESSE, DANS UN PREMIER TEMPS, AU MODELE B.G.K. POUR L'EQUATION DE BOLTZMANN DE LA DYNAMIQUE DES GAZ QUE NOUS AVONS RESOLUE A L'AIDE D'UNE METHODE PARTICULAIRE. CE TRAVAIL A CONSISTE TOUT D'ABORD EN L'ANALYSE MATHEMATIQUE DU MODELE B.G.K., CE QUI NOUS A PERMIS DE DEVELOPPER UNE ANALYSE THEORIQUE COMPLETE DE LA CONVERGENCE DE LA METHODE. DANS UN SECOND TEMPS, NOUS AVONS IMPLEMENTE CETTE METHODE SUR DES MACHINES D'ARCHITECTURE DIVERSES (VECTORIELLE ET PARALLELE). LA DEUXIEME PARTIE A CONSISTE A UTILISER LES METHODES DEVELOPPEES POUR SIMULER L'EVOLUTION DE PARTICULES RELATIVISTES SOUMISES A DES CHAMPS ELECTROMAGNETIQUES. LE MODELE PHYSIQUE UTILISE EST LE SYSTEME DE VLASOV-MAXWELL. LES EQUATIONS DE MAXWELL SONT RESOLUES ICI A L'AIDE D'UNE METHODE DE VOLUMES FINIS ET L'EQUATION DE VLASOV A L'AIDE D'UNE METHODE PARTICULAIRE. ON PRESENTE ENFIN UNE NOUVELLE FORMULATION DES EQUATIONS DE MAXWELL AFIN DE MIEUX VERIFIER, AU NIVEAU DISCRET, LES RELATIONS DE DIVERGENCE POUR LE CHAMP ELECTROMAGNETIQUE. ON MONTRERA, EN ETABLISSANT LES EQUATIONS EQUIVALENTES, POURQUOI CES RELATIONS SONT MIEUX VERIFIEES EN CONSIDERANT CETTE NOUVELLE FORMULATION

Book Synopsis Méthode adaptative de raffinement local multi-niveaux pour le calcul d'écoulements réactifs à faible nombre de Mach by : Xavier Coré
Download or read book Méthode adaptative de raffinement local multi-niveaux pour le calcul d'écoulements réactifs à faible nombre de Mach written by Xavier Coré and published by . This book was released on 2002 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: L'approximation isobare du système d'équation de bilan de masse, de quantité de mouvement, d'énergie et des espèces chimiques est une approximation appropriée pour représenter les écoulements réactifs à faible nombre de Mach. Dans cette approximation, qui néglige les phénomènes acoustiques, le mélange est hydrodynamiquement incompressible et les effets thermodynamiques conduisent à une compression uniforme du système. Nous présentons une nouvelle méthode numérique pour cette approximation. Une méthode de projection incrémentale, qui utilise la forme originale du bilan de masse, assure la discrétisation temporelle des équations de Navier-stokes. La discrétisation spatiale est réalisée avec une méthode de volumes finis sur maillage décalé de type MAC. Un schéma de décentrement d'ordre élevé est utilisé pour l'estimation des flux convectifs. Nous associons à cette discrétisation, une méthode de raffinement local multi-niveaux, basée sur l'approche de Correction en Flux à l'Interface. Une première application concerne un écoulement forcé avec masse volumique variable donnée, imitant un problème de combustion. La deuxième application est le problème de convection naturelle, tout d'abord pour de faibles variations de température puis au-delà de la limite de validité de l'approximation de Boussinesq. Enfin, la troisième application est une flamme de diffusion laminaire. Pour chacun de ces cas-test, nous montrons la robustesse de la méthode numérique proposée, notamment vis à vis des variations de la masse volumique. Et nous analysons le gain en précision obtenu par la méthode de raffinement local multi-niveaux.

Book Synopsis Arctic Human Development Report by : Joan Nymand Larsen
Download or read book Arctic Human Development Report written by Joan Nymand Larsen and published by Nordic Council of Ministers. This book was released on 2015-02-18 with total page 507 pages. Available in PDF, EPUB and Kindle. Book excerpt: The goals of the second volume of the AHDR – Arctic Human Development Report: Regional Processes and Global Linkages – are to provide an update to the first AHDR (2004) in terms of an assessment of the state of Arctic human development; to highlight the major trends and changes unfolding related to the various issues and thematic areas of human development in the Arctic over the past decade; and, based on this assessment, to identify policy relevant conclusions and key gaps in knowledge, new and emerging Arctic success stories. The production of AHDR-II on the tenth anniversary of the first AHDR makes it possible to move beyond the baseline assessment to make valuable comparisons and contrasts across a decade of persistent and rapid change in the North. It addresses critical issues and emerging challenges in Arctic living conditions, quality of life in the North, global change impacts and adaptation, and Indigenous livelihoods. The assessment contributes to our understanding of the interplay and consequences of physical and social change processes affecting Arctic residents’ quality of life, at both the regional and global scales. It shows that the Arctic is not a homogenous region. Impacts of globalization and environmental change differ within and between regions, between Indigenous and non-Indigenous northerners, between genders and along other axes.
Book Synopsis Governing Climate Change by : Harriet A Bulkeley
Download or read book Governing Climate Change written by Harriet A Bulkeley and published by Routledge. This book was released on 2010-02-26 with total page 293 pages. Available in PDF, EPUB and Kindle. Book excerpt: Governing Climate Change provides a short and accessible introduction to how climate change is governed by an increasingly diverse range of actors, from civil society and market actors to multilateral development banks, donors and cities. The issue of global climate change has risen to the top of the international political agenda. Despite ongoing contestation about the science informing policy, the economic costs of action and the allocation of responsibility for addressing the issue within and between nations, it is clear that climate change will continue to be one of the most pressing and challenging issues facing humanity for many years to come. The book: evaluates the role of states and non-state actors in governing climate change at multiple levels of political organisation: local, national and global provides a discussion of theoretical debates on climate change governance, moving beyond analytical approaches focused solely on nation-states and international negotiations examines a range of key topical issues in the politics of climate change includes multiple examples from both the north and the global south. Providing an inter-disciplinary perspective drawing on geography, politics, international relations and development studies, this book is essential reading for all those concerned not only with the climate governance but with the future of the environment in general.
Book Synopsis Rethinking the Region by : John Allen
Download or read book Rethinking the Region written by John Allen and published by Routledge. This book was released on 2012-12-06 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rethinking the Region argues that regions are not simply bounded spaces on a map. This book uses unique research of England during the 1980s to show how regions are made and unmade by social processes. The book examines how new lines of division both social and geographical were laid down as free-market growth and reconstructed this are as a `neo-liberal' region. The authors argue that a more balanced form of growth is possible - within and between regions as well as between social groups. This book shows that to grasp the complexities of growth we must rethink `the region' in time as well as in space.

Download or read book Biomimicry written by Janine M. Benyus and published by Harper Collins. This book was released on 2009-08-11 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: Repackaged with a new afterword, this "valuable and entertaining" (New York Times Book Review) book explores how scientists are adapting nature's best ideas to solve tough 21st century problems. Biomimicry is rapidly transforming life on earth. Biomimics study nature's most successful ideas over the past 3.5 million years, and adapt them for human use. The results are revolutionizing how materials are invented and how we compute, heal ourselves, repair the environment, and feed the world. Janine Benyus takes readers into the lab and in the field with maverick thinkers as they: discover miracle drugs by watching what chimps eat when they're sick; learn how to create by watching spiders weave fibers; harness energy by examining how a leaf converts sunlight into fuel in trillionths of a second; and many more examples. Composed of stories of vision and invention, personalities and pipe dreams, Biomimicry is must reading for anyone interested in the shape of our future.

Book Synopsis Tourism and Regional Development by : Maria Giaoutzi
Download or read book Tourism and Regional Development written by Maria Giaoutzi and published by Routledge. This book was released on 2017-05-15 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tourist visits used to be a less common activity in the past. However, more people than ever now make leisure trips, making this an era of mass tourism. This drastic change in spatial behaviour is not only caused by economic prosperity, but the scale of this phenomenon means that it is able to generate economic growth, making tourism a key factor in regional development policy. One of the main challenges of current regional policy is to market the attractiveness of an area, thereby increasing tourist visits and subsequent revenue. In particular, regions are attempting this through the use of Information and Communication Technologies (ICT), which offer information on interesting places, and efficient methods for organizing and booking trips. This book examines the interconnections between tourism, ICT and regional development. Bringing together a range of European case studies illustrating various ICT and policy innovations, it not only critiques current activity by regions in terms of tourism development, but also considers how this sector is likely to continue to grow.
