• Sommario/riassunto: This book provides the fundamental basics for solving fluid structure interaction problems, and describes different algorithms and numerical methods used to solve problems where fluid and structure can be weakly or strongly coupled. These approaches are illustrated with examples arising from industrial or academic applications. Each of these approaches has its own performance and limitations. Given the book's comprehensive coverage, engineers, graduate students and researchers involved in the simulation of practical fluid structure interaction problems will find this book extremely useful.

• Sommario/riassunto: The explosion of transnational information flows, made possible by new technologies and institutional changes (economic, political and legal) has profoundly affected the study of global media. At the same time, the globalization of media combined with the globalization of higher education means that the research and teaching of the subject faces immediate and profound challenges, not only as the subject of enquiry but also as the means by which researchers and students undertake their studies.Edited by a leading scholar of global communication, this collection of essays by int
