The proceedings reflect a broad spectrum of topics in contemporary theoretical physics: quantum aspects of black holes; recent progress in critical and noncritical string theory; spin chains quantum hall effect and generalized statistics; stochastic dynamics turbulence and reaction kinetics; foundations of quantum mechanics; new statistics in field theory; quantum field theory on Riemann surfaces and knot theory; lattice field theories. The lectures present developments in the frontiers of these subjects and provide interdisciplinary links between the areas.

The shift from network-oriented to user-oriented services in the 80s and early 90s has increased the penetration of satellite services into the user community. Parallel to this, worldwide interest has arisen in Personal Communication Services (PCS), where satellites play a crucial role in the provision of PCS all over the world. Satellite Personal Communication Networks (S-PCN) are extremely attractive because they can serve a significant sector of the rapidly growing cellular market. This publication presents market perspectives and technological aspects in relation to satellite mobile and personal communication services. Papers were written by some of the most acclaimed European specialists in PCS. They present basic concepts and the latest research results.

Demand for Mobile Satellite Service (MSS) is on the increase, with a huge surge of interest in mobile communications in recent years and high-paced advancements in the supporting system architectures, devices and applications. This thoroughly revised and updated book provides a comprehensive guide to the MSS technologies and emerging trends. It takes a system level approach, giving in-depth treatment of technical and business related issues. The author, a leading professional in the area, draws on his extensive experience in industry and research, to provide the reader with a sound and informed understanding of the technology. Mobile Satellite Communications includes introductory material for the reader new to the field, in addition to exploring prevalent system concepts, architecture, practices and trends for the more experienced. An in-depth review of scientific principles merged with business models and regulatory considerations presents a balanced perspective of commercial mobile satellite systems. This book will be of interest to practicing engineers in mobile satellite communications and mobile broadcasting, research and development professionals working in these areas, mobile satellite service providers and operators. Academics and students studying satellite systems/technology, specialists in other classes of satellite systems, technical and marketing managers, strategists and planners of telecommunication systems: individuals interested in mobile communications, satellite and telecommunications/broadcasting technology will also find this book insightful. Key Features: Comprehensive treatment of mobile satellite communications topics, including radio link aspects, satellite constellations, architectural and operational aspects, as well as business planning models, MSS radio interface standards, spectrum forecast methodologies and system examples. Addresses related themes such as mobile broadcasting, mobile VSATs, search and rescue, and navigation systems. Introduces emerging technologies such as mobile broadband, television broadcasting to handheld units, advanced capacity enhancement techniques, hybrid system architecture concepts, including a rich sample of research topics such as multiple input multiple output, satellite-based ad-hoc networks, and highlights initiatives in the use of Q/V frequency bands. Includes revision questions at the end of each chapter. An accompanying website for interaction (www.satellitesandyou.com).

Satellite Network Robust QoS-aware Routing presents a novel routing strategy for satellite networks. This strategy is useful for the design of multi-layered satellite networks as it can greatly reduce the number of time slots in one system cycle. The traffic prediction and engineering approaches make the system robust so that the traffic spikes can be handled effectively. The multi-QoS optimization routing algorithm can satisfy various potential user requirements. Clear and sufficient illustrations are also presented in the book. As the chapters cover the above topics independently, readers from different research backgrounds in constellation design, multi-QoS routing, and traffic engineering can benefit from the book.
