Ce travail présente une technique de simulation de feux de forêt qui utilise la méthode Level-Set. On utilise une équation aux dérivées partielles pour déformer une surface sur laquelle est imbriqué notre front de flamme. Les bases mathématiques de la méthode Level-set sont présentées. On explique ensuite une méthode de réinitialisation permettant de traiter de manière robuste des données réelles et de diminuer le temps de calcul. On étudie ensuite l'effet de la présence d'obstacles dans le domaine de propagation du feu. Finalement, la question de la recherche du point d'ignition d'un incendie est abordée.

Report presents a series of analyses and recommendations for fostering the role of culture for sustainable development. Drawing on a global survey implemented with nine regional partners and insights from scholars, NGOs and urban thinkers, the report offers a global overview of urban heritage safeguarding, conservation and management, as well as the promotion of cultural and creative industries, highlighting their role as resources for sustainable urban development. Report is intended as a policy framework document to support governments in the implementation of the 2030 Agenda for Sustainable Urban Development and the New Urban Agenda.

The Green Challenge is an up-to-date and comprehensive account of the development of Green parties in Western Europe, and includes an account of the development since 1989 of an East European Green movement. Blending theory and empirical analysis, the book contains chapters on each of the main western European cases and on a number of other less-studied ones. These are designed to demonstrate the shifting balance of party-political competition the factor the authors believe most strongly influences the fortunes of the Greens. The editors also integrate a valuable analysis of the environmentally-degraded Czech Republic, where the Green parties' lack of electoral success has puzzled many observers.

In this book, the author compares New Social Movements (NSM) development in France with NSM development in Switzerland, Germany and the Netherlands. He finds that by the 1980s, the new social movements were weaker in France because of France's tradition of old political conflicts.

The discussion about a constitution for the European Union and its rejection by referendum in two of the EU founding member states has once again spurred public and scholarly interest in the democratic quality and potential of the European Union. Debating the Democratic Legitimacy of the European Union brings together distinguished thinkers from law, political science, sociology, and political philosophy to explore the potential for democratically legitimate governance in the European Union. Drawing on different theoretical perspectives and strands from democratic theory, this volume is the first of its kind to overcome the present state of fragmentation in the debate about the conditions and possible remedies for what is often called the "democratic deficit" of the European Union. Among the pressing questions addressed by the contributors are: What future is there for parliamentary democracy in the European Union? Can we observe the evolution of a European public sphere and civil society? Can participatory democracy or deliberative democracy pave the road for a democratically legitimate European Union? Conversations about democracy have engaged the public in a new way since the beginning of the Iraq war, and this volume is the best resource for students and readers who are interested in democracy in the European Union.

Dr. Chun's Aerospace Power in the Twenty-First Century: A Basic Primer is a great start towards understanding the importance of aerospace power and its ability to conduct modern warfare. Aerospace power is continually changing because of new technology, threats, and air and space theories. However, many basic principles about aerospace power have stood the test of time and warfare. This book provides the reader with many of these time-tested ideas for consideration and reflection. Although Aerospace Power in the Twenty-First Century was written for future officers, individuals desiring a broad overview of aerospace power are invited to read, share, and discuss many of the ideas and thoughts presented here. Officers from other services will find that this introduction to air and space forces will give them a good grasp of aerospace power. More experienced aerospace leaders can use this book to revisit many of the issues that have affected air and space forces in the past and that might affect them in the future. Air Force officers will discover that Aerospace Power in the Twenty-First Century is a very timely and reflective resource for their professional libraries.
