This book constitutes revised selected papers from the Conference on Energy Efficiency in Large Scale Distributed Systems, EE-LSDS, held in Vienna, Austria, in April 2013. It served as the final event of the COST Action IC0804 which started in May 2009. The 15 full papers presented in this volume were carefully reviewed and selected from 31 contributions. In addition, 7 short papers and 3 demo papers are included in this book. The papers are organized in sections named: modeling and monitoring of power consumption; distributed, mobile and cloud computing; HPC computing; wired and wireless networking; and standardization issues.

Refereed post-proceedings of the First International Workshop on Data Management in Grids, in Trondheim, Norway. The 11 papers in this book address current research activities in relation to data management in dynamic, heterogeneous and cross-organizational environments, or grids. They show expertise in the management of very large, widely distributed databases. Conversely, Grids offer a novel and exciting field of research for database scientists in application domains and for fundamental research.

‘Magical Doors’ is not only a wildly entertaining guide to what the houses, planets and signs represent, but it skilfully shows how they came into being and how they work together and influence each other. Jean-Marc’s knowledge, wit, and wisdom shine through his passionate descriptions, inspiring astrologers and non-astrologers alike. Finally, a book that makes sense of it all – and does so magnificently!
