Going far beyond the standard texts, this book extensively covers boundary integral equation (BIE) formulations and the boundary element method (BEM). The first section introduces BIE formulations for potential and elasticity problems, following the modern regularization approach - the fundamental starting point for research in this field. Secondly, a clear description of BIE formulations for wave and elastodynamics problems, in both time and frequency domains is presented. Finally, recent research in the field, related to variational integral formulations, use of geometrical symmetry, shape sensitivity and fracture mechanics is summarised. Within the text a broad range of application areas, industrial as well as research related, are examined. These include:

• elasticity and small-strain elastoplasticity
• time-domain and frequency-domain scalar and elastic waves
• fracture mechanics

Including an extensive bibliography, this text will be of considerable value and interest to graduate students, researchers and lecturers in engineering mechanics, applied maths and physics, as well as industrial practitioners working within these areas.

With the end of the Cold War, will the space race become a cooperative venture? This book, which tells the story of the European Space Agency, shows how such a cooperative enterprise has worked over the past three decades and how it might apply to future space science.

Linking fifteen European nations, the European Space Agency offers a working model of scientific, technological, and political cooperation on an international scale. Roger M. Bonnet and Vittorio Manno give us an insiders' view of the agency--its beginnings as the European Space Research Organization, its development in the face of early difficulties, and its daily operations. Covering thirty years, this account traces the evolution of ESAs programs, facilities, and capabilities and the establishment of its scientific, technological, industrial, and political policies and objectives. With an eye to future global space activities, the authors detail ESA's relationships with its own member states and with other countries, particularly the United States. The history of cooperation between ESA and NASA as exemplified by two specific projects--Ulysses and the international space station--highlights the difficulties of associating different decisionmaking bodies and political systems.

Illustrated with pictures and diagrams, enlivened with anecdotes involving key world players in space science, this book provides a rich blend of factual information and personal recollection, history and interpretation. A timely contribution to the study of the politics of science and technology, it points the way to future international cooperation.
