Book excerpt: Aujourd'hui, dans un contexte intellectuel favorable et sous l'effet stimulant de la crise de l'energie, l'energie eolienne connait un regain d'interet et un nouvel essor industriel dans le monde. Dans ce livre, on propose une contribution a l'amelioration de la commande d'un systeme eolien muni d'une machine asynchrone doublement alimentee. On s'est particulierement interesse au fonctionnement du systeme en presence de defauts, et on a propose une reconfiguration de la commande en vue d'assurer une continuite de service avec un bon degre de performance. Deux types de defaut ont ete etudies: le premier concerne le defaut capteur de courant. Le deuxieme concerne le defaut provenant du reseau electrique. Une etude du cas des perturbations de grandes amplitudes du reseau a ete egalement effectuee. En effet, pour garantir la continuite de fonctionnement, on a opte pour l'utilisation du circuit Crowbar. Et pour venir en aide au reseau en defaut on a propose une procedure speciale, qui permet au systeme eolien de fonctionner sous tension reduite."

Book excerpt: Les systèmes éoliens seront certainement amenés, à court terme, à contribuer aux services systèmes (compensation de la puissance réactive, stabilité du plan de tension,...) comme le font actuellement les alternateurs de centrales classiques. Ils seront également amenés à participer à l'amélioration de la qualité de l'énergie électrique, filtrage des courants harmoniques en particulier. De plus, vu l'augmentation de la puissance éolienne installée et fournie au réseau électrique, les éoliennes devront certainement assurer, à plus long terme, une continuité de service suite à un défaut électrique sur le réseau ou sur un des éléments de la chaîne de conversion électromécanique (interrupteurs de puissance, capteurs,...) afin d'améliorer leur fiabilité. Dans ces travaux de thèse, nous avons montré dans un premier temps qu'un système éolien basé sur une Machine Asynchrone à Double Alimentation (MADA) possédant un gain d'amplification entre les courants rotoriques et statoriques peut participer efficacement à l'amélioration de la qualité de l'énergie électrique en compensant simultanément de la puissance réactive et des courants harmoniques présents sur le réseau, sans pour autant nécessiter un surdimensionnement des éléments de la chaîne de conversion électromécanique. Ensuite, nous avons étudié des topologies dites “fault tolerant” de convertisseurs statiques triphasés et leurs commandes associées, permettant de garantir la continuité de service en présence de défauts éventuels d'un semi-conducteur ou d'un capteur de courant. Pour réduire autant que possible le temps de détection de défaut, nous avons ciblé un composant FPGA (Field Programmable Gate Array) pour le contrôle/commande “fault tolerant”. Les résultats de simulation, de prototypage “FPGA in the loop” et expérimentaux démontrent les performances des méthodes proposées.

Book excerpt: Soils are affected by human activities, such as industrial, municipal and agriculture, that often result in soil degradation and loss. In order to prevent soil degradation and to rehabilitate the potentials of degraded soils, reliable soil data are the most important prerequisites for the design of appropriate land-use systems and soil management practices as well as for a better understanding of the environment. The availability of reliable information on soil morphology and other characteristics obtained through examination and description of the soil in the field is essential, and the use of a common language is of prime importance. These guidelines, based on the latest internationally accepted systems and classifications, provide a complete procedure for soil description and for collecting field data. To help beginners, some explanatory notes are included as well as keys based on simple test and observations.--Publisher's description.

Available in PDF, EPUB and Kindle. Book excerpt: In 2015, the General Assembly of State Parties to the World Heritage Convention passed a ground-breaking Sustainable Development policy that seeks to bring the World Heritage system into line with the UN’s sustainable development agenda (UNESCO 2015). World Heritage and Sustainable Development provides a broad overview of the process that brought about the new policy and the implications of its enactment. The book is divided into four parts. Part I puts the policy in its historical and theoretical context, and Part II offers an analysis of the four policy dimensions on which the policy is based – environmental sustainability, inclusive social development, inclusive economic development and the fostering of peace and security. Part III presents perspectives from IUCN, ICOMOS and ICCROM – the three Advisory Bodies to the World Heritage Committee, and Part IV offers ‘case study’ perspectives on the practical implications of the policy. Contributions come from a wide range of experienced heritage professionals and practitioners who offer both ‘inside’ perspectives on the evolution of the policy and ‘outside’ perspectives on its implications. Combined, they present and analyse the main ideas, debates and implications of the policy change. This book is key reading for all heritage professionals interested in developing a better understanding of the new Sustainable Development policy. It is also essential reading for scholars and students working in the area.

Book excerpt: The International Conference on Environment: Survival and Sustainability, held at the Near East University, Nicosia, Northern Cyprus 19-24 February 2007, dealt with environmental threats and proposed solutions at all scales. The 21 themes addressed by the conference fell into four broad categories; Threats to Survival and Sustainability; Technological Advances towards Survival and Sustainability; Activities and Tools for Social Change; Defining Goals for Sustainable Societies. Activities and tools that move the society towards greater sustainability were emphasized at the conference. These included environmental law and ethics, environmental knowledge, technology and information systems, media, environmental awareness, education and lifelong learning, the use of literature for environmental awareness, the green factor in politics, international relations and environmental organizations. The breadth of the issues addressed at the conference made clear the need for greatly increased interdisciplinary and international collaboration the survival and sustainability concept. The exchanges at the conference represent a step in this direction.

Available in PDF, EPUB and Kindle. Book excerpt: The concept of sustainable development is a source of inspiration for many, who see it as a call to cooperative action. In practice, however, policies intended to further this goal often generate conflicts of interest. The ensuing disputes occur among governmental organizations, but disputes also arise between public authorities, private interest groups, and the environmental movement. In the opinion of the authors, the fact that environmental policy can provoke such conflict may be attributed largely to decision making procedures in our society. Accordingly, the authors are convinced that a new approach to managing environmental disputes is needed in order to deal effectively with environmental problems. Indeed, this book presents a viable alternative, which is called network management.

Available in PDF, EPUB and Kindle. Book excerpt: In this 1994 book, Xavier de Planhol and Paul Claval, two of France's leading scholars in the field, trace the historical geography of their country from its roots in the Roman province of Gaul to the 1990s. They demonstrate how, for centuries, France was little more than an ideological concept, despite its natural physical boundaries and long territorial history. They examine the relatively late development of a more complex territorial geography, involving political, religious, cultural, agricultural and industrial unities and diversities. The conclusion reached is that only in the twentieth century had France achieved a profound territorial unity and only now are the fragmentations of the past being overwritten.
