The growing power of modern workstations enables engineers to simulate more and more complex mechanical models by computers. In particular, nonlinear problems from structural dynamics are computationally intensive. Hence, there is ongoing demand for improvement of existing algorithms. This PhD thesis deals with the simulation of the dynamics of flexible bodies subject to constitutive and geometrical nonlinearities, as well as discontinuous phenomena arising from collisions. Procedures covered by this book are: Hamiltons principle, properties of variational mechanics, explicit variational...

Bevor wir mit fotorealistischen Charakteren durch epische 3D-Welten wanderten, fanden die größten Abenteuer der Spielegeschichte auf Küchentischen statt - bewaffnet nur mit Stiften, Papier und seltsam geformten Würfeln. Die Wurzeln der modernen, milliardenschweren Rollenspiel-Industrie liegen tief begraben in den nerdigen Kellern der 1970er Jahre. Von Dungeons & Dragons bis hin zu komplexen digitalen Meisterwerken wie Baldur's Gate: Die DNA der Videospiele ist untrennbar mit der Mathematik und der Vorstellungskraft der klassischen Tabletop-Rollenspiele verbunden.Dieses spannende Sachbuch...

This book focuses on tropical coasts, which are highly vulnerable due to a multitude of stressors. Population growth is substantial, habitats are lost and biodiversity is reduced at an alarming rate, severely affecting many ecosystem services. This situation calls for sound coastal management and the effective engagement of all relevant stakeholders.About two decades ago the M.Sc. program ISATEC (International Studies in Aquatic Tropical Ecology) was created at Bremen University (Germany) to train young scientists for a professional engagement in the complex field of tropical coastal and...
