The workshop on Computability and Complexity in Analysis, CCA 2000, was hosted by the Department of Computer Science of the University of Wales Swansea, September 17{19, 2000. It was the fourth workshop in a successful series of workshops: CCA’95 in Hagen, Germany, CCA’96 in Trier, Germany, and CCA’98 in Brno, Czech Republic. About 40 participants from the countries United Kingdom, Germany, Japan, Italy, Russia, France, Denmark, Greece, and Ireland contributed to the success of this meeting. Altogether, 28 talkswere p- sented in Swansea. These proceedings include 23 papers which represent a cro- section through recent research on computability and complexity in analysis. The workshop succeeded in bringing together people interested in computability and complexity aspects of analysis and in exploring connections with nume- cal methods, physics and, of course, computer science. It was rounded o by a number of talks and papers on exact computer arithmetic and by a competition of v e implemented systems. A report on this competition has been included in these proceedings. We would like to thank the authors for their contributions and the referees for their careful work, and we hope for further inspiring and constructive meetings of the same kind.

This book is a review of the most up-to-date observational and theoretical information concerning the chemical evolution of the Milky Way. A comparison between the abundances derived from field stars and clusters is presented together with information on the abundances and dynamics of gas. The role of supernovae and novae on the chemical enrichment history of our Galaxy is discussed in the framework of the most advanced and detailed chemical evolution models. The difficulties in obtaining reliable abundance measurements as well as precise predictions about stellar nucleosynthesis and chemical abundances in the interstellar medium are critically discussed by specialists in the field. Possible mechanisms for the formation and evolution of the Milky Way are suggested on the basis of comparison between theory and observations.

Cities concentrate wealth, people and productivity while consuming much of the world's energy and producing much of the world's greenhouse gas emissions. This concentration makes cities and their populations more at risk to natural disasters and to long-term changes in climate, yet cities also offer vast opportunities to respond to these challenges. Changes in migration, land use, and spatial development will increase vulnerability, especially in developing countries, and rising sea levels will affect millions of people living in coastal cities. Adaptation, mitigation, and increased resilience to climate change are therefore imperative for cities. The links between cities and climate change were the subject of the 5th Urban Research Symposium held in Marseille, France, in June 2009. The eight papers selected and updated for Cities and Climate Change: Responding to an Urgent Agenda reflect the core of the analytical discussion and policy implications discussed at the symposium, combining comprehensive analysis and theoretical insights with examples of best practices from around the world. These include a framework to include aspects of poverty in the discussion of cities and climate change; new perspectives on the knowledge and measurement of climate change, urban infrastructure, institutions and governance, and economic and social issues; and specific case studies comparing experiences of cities in both industrialized and developing countries. This book also includes a summary discussion of the main research themes and abstracts of additional selected papers from the symposium. --Book Jacket.

This book constitutes the refereed proceedings of the Second International Workshop on Intelligent Agents for Telecommunication Applications, IATA'98, held in Paris, France, in July 1998, in conjunction with the 1998 Agents World Conference. The book presents 17 revised full papers carefully selected for inclusion in the volume. The book is divided into topical sections on network architecture, network configuration and planning, network optimization, network management, agent-based architectures for service applications.
