Available in PDF, EPUB and Kindle. Book excerpt: Les commandes numériques habituellement utilisées pour commander les machines-outils engagées dans la réalisation d'une opération de tournage sont basées sur la mise en oeuvre de boubles d'asservissement des vitesses d'avance et de rotation de la broche. Nous avons proposé avec notre travail une extention des principes de contrôle par l'introduction de boucles supplémentaires de régulation adaptative. Ces dernières utilisent des stratégies avancées d'identification et de commande en temps réel pour asservir l'effort de coupe afin d'obtenir un gain significatif en productivité. Dans ce contexte, les développements que nous avons menés sont situés à l'intersection de la mécanique, par utilisation des principes et règles de conduite d'usinage, et de l'automatique, par la conception des algorithmes d'identification et de commande. La démarche générale a consisté à étudier des modèles statistiques et dynamiques du processus de tournage, à concevoir et à tester en simulation des stratégies de commande adaptative et enfin à réaliser la validation et l'adaptation sur une machine-outil cible. Pour définir une stratégie de commande adaptative satisfaisante, nous avons completé d'une manière progressive les algorithmes proposés. A partir du régulateur P.I.D. nous avons ensuite considéré des commandes par retour d'état : commande par placement de pôles avec compensation partielle de la non linéarité utilisant l'approche DELTA et commande optimale linéaire quadratique avec compensation complète de la non linéarité. Nous avons aussi proposé un couplage original d'un modèle dynamique du processus de tournage avec un modèle analytique de prédiction de l'usure de l'outil. Pour la validation avec la machine cible, nous avons utilisé une méthode de régulation numérique robuste basée sur la calibrage de la fonction de sensibilité perturbation-sortie.

Book excerpt: Preface Adhesion is a phenomenon architects and civil engineers are not very familiar with. In other disciplines knowledge about surface properties and the background of bonding energies is also far from satisfactory; nevertheless there are many important· applications in concrete engineering, where adhesion is necessary for success and durability. These include: - coating and painting - repair of concrete surfaces - bonding of fresh to old concrete - crack injection - glueing of precast elements - glueing of steel to concrete, etc. In 1981 RILEM established the technical committee 52-RAC 'Resin Adherence to Concrete'. The main aims of the committee's work were - to collect research results and practical experiences - to initiate and coordinate research programs - to develop, on a scientific base, test methods for field and for laboratory purposes. One of the results of the committee's work is a state-of-the-art report, which will be presented orally as a General Report at the International Symposium ISAP '86, and will be printed either in the RILEM journal Materials and Structures or separately. Several test recommendations have been elaborated and will be prepared as drafts for the participants ofISAP '86. These are: - direct tensile test - pull-off test - direct shear test - slant shear test - four-point bending test - dynamic loading test - thermal compatibility test (two versions) - injectibility test.

Book excerpt: In-depth interviews with the main movers in the punk rock movement--Crass members Penny Rimbaud, Gee Vaucher, and Steve Ignorant--detail the face of the revolution founded by these radical thinkers and artists. When punk ruled the waves, Crass waived the rules by putting out their own records, films, and magazines and setting up a series of situationist pranks that were dutifully covered by the world's press. Not just another iconoclastic band, Crass was a musical, social, and political phenomenon: commune dwellers that were rarely photographed and remained contemptuous of conventional pop stardom. As detailed in this history, their members explored and finally exhausted the possibilities of punk-led anarchy. This definitive biography of the band not only gives backstage access to their lives, philosophies, and the movement that followed, but also to never-before-seen photographs and rare dialogues.

Available in PDF, EPUB and Kindle. Book excerpt: Protected areas are at the base of the most national and international conservation strategies. Due to the many unpredictable elements in ecology matters, each protected area requires a case-specific set of guidelines but a common issue is how to cope with human interaction. The management of protected areas is replete with challenges and the only way to gain understanding and achieve greater management possibilities is to exchange experiences and knowledge. Environmental managers are aware of that and together with scientists are looking for more modern and better solutions, both with respect to natural resources and human interactions in many issues regarding nature protection. This publication presents reviews and research results on protected areas management, as well as 12 case studies derived from around the world with the aim of improving management effectiveness of the protected areas.

This book was released on 2012-03-30 with total page 600 pages. Available in PDF, EPUB and Kindle. Book excerpt: With over half the world's population now deemed to be urbanised, cities are assuming a larger role in political debates about the security and sustainability of the global food system. Hence, planning for sustainable food production and consumption is becoming an increasingly important issue for planners, policymakers, designers, farmers, suppliers, activists, business and scientists alike. The rapid growth of the food planning movement owes much to the fact that food, because of its unique, multi-functional character, helps to bring people together from all walks of life. In the wider contexts of global climate change, resource depletion, a burgeoning world population, competing food production systems and diet-related public health concerns, new paradigms for urban and regional planning capable of supporting sustainable and equitable food systems are urgently needed. This book addresses this urgent need. By working at a range of scales and with a variety of practical and theoretical models, this book reviews and elaborates definitions of sustainable food systems, and begins to define ways of achieving them. To this end 4 different themes have been defined as entry-points into the discussion of 'sustainable food planning'. These are (1) urban agriculture, (2) integrating health, environment and society, (3) food in urban design and planning and (4) urban food governance.

Available in PDF, EPUB and Kindle. Book excerpt: This comprehensive overview of local food systems explores alternative definitions of local food, estimates market size and reach, describes the characteristics of local consumers and producers, and examines early indications of the economic and health impacts of local food systems. Defining ¿local¿ based on marketing arrangements, such as farmers selling directly to consumers at regional farmers¿ markets or to schools, is well recognized. Statistics suggest that local food markets account for a small, but growing, share of U.S. agricultural production. For smaller farms, direct marketing to consumers accounts for a higher percentage of their sales than for larger farms. Charts and tables.

Available in PDF, EPUB and Kindle. Book excerpt: The Oxford Handbook of Creative Industries is a reference work, bringing together many of the world's leading scholars in the application of creativity in economics, business and management, law, policy studies, organization studies, and psychology. Creative industries research has become a regular theme in academic journals and conferences across these subjects and is also an important agenda for governments throughout the world, while business people from established companies and entrepreneurs revaluate and innovate their models in creative industries. The Handbook is organized into four parts: Following the editors' introduction, Part One on Creativity includes individual creativity and how this scales up to teams, social networks, cities, and labour markets. Part Two addresses Generating and Appropriating Value from Creativity, as achieved by agents and organizations, such as entrepreneurs, stars and markets for symbolic goods, and considers how performance is measured in the creative industries. Part Three covers the mechanics of Managing and Organizing Creative Industries, with chapters on the role of brokerage and mediation in creative industry networks, disintermediation and glocalisation due to digital technology, the management of project-based organzations in creative industries, organizing events in creative fields, project ecologies, Global Production Networks, genres and classification and sunk costs and dynamics of creative industries. Part Four on Creative Industries, Culture and the Economy offers chapters on cultural change and entrepreneurship, on development, on copyright, economic spillovers and government policy. This authoritative collection is the most comprehensive source of the state of knowledge in the increasingly important field of creative industries research. Covering emerging economies and new technologies, it will be of interest to scholars and students of the arts, business, innovation, and policy.

Book excerpt: Pakistan is unlike most other countries in the emerging world. It is one of the two nations – the other being the state of Israel – founded on the basis of religion. Although it was created to provide a homeland for the Muslim community of British India, in its original form it was able to accommodate only about half of the people of Islamic faith who lived in the subcontinent. Pakistan’s birth in 1947 resulted in one of the largest movements of people in human history when some 14 million people left their homes, with 8 million Muslims leaving India for what is now Pakistan and 6 million Hindus and Sikhs moving in the opposite direction. This was the first large-scale incidence of ethnic cleansing the world was to witness. --
