Born after World War II, large-scale experimental high-energy physics (HEP) has found itself limited ever since by available accelerator, detector and computing technologies. Accordingly, HEP has made significant contributions to the development of these fields, more often than not driving their innovations. The invention of the World Wide Web at CERN is merely the best-known example out of many. This book is the first comprehensive account to trace the history of this pioneering spirit in the field of computing technologies. It covers everything up to and including the present-day handling of the huge demands imposed upon grid and distributed computing by full-scale LHC operations—operations which have for years involved many thousands of collaborating members worldwide and accordingly provide the original and natural testbed for grid computing concepts. This book takes the reader on a guided tour encompassing all relevant topics, including programming languages, software engineering, large databases, the Web, and grid- and cloud computing. The important issue of intellectual property regulations for distributed software engineering and computing is also addressed. Aptly, the book closes with a visionary chapter of what may lie ahead. Approachable and requiring only basic understanding of physics and computer sciences, this book is intended for both education and research.

Role-based access control (RBAC) is a widely used technology to control information flows as well as control flows within and between applications in compliance with restrictions implied by security policies, in particular, to prevent disclosure of information or access to resources beyond restrictions defined by those security policies. Since RBAC only provides the alternatives of either granting or denying access, more fine-grained control of information flows such as “granting access to information provided that it will not be disclosed to targets outside our organisation during further processing” is not possible. In business processes, in particular those spanning several organisations, which are commonly defined using business process execution language (BPEL), useful information flows not violating security policy-implied limitations would be prevented if only the access control capabilities offered by RBAC are in use. The book shows a way of providing more refined methods of information flow control that allow for granting access to information or resources by taking in consideration the former or further information flow in a business process requesting this access. The methods proposed are comparatively easy to apply and have been proven to be largely machine-executable by a prototypical realisation. As an addition, the methods are extended to be also applicable to BPEL-defined workflows that make use of Grid services or Cloud services.

The number one problem in our world today is effective energy management--the energy that fuels our buildings and propels our vehicles as well as our human energy. But if individuals, governments, and corporations take action now, we can have a bright energy future. In Beyond Light Bulbs, Susan Meredith helps readers move beyond the gloom, doom, and overwhelm of global warming and the energy crisis. She offers hopeful and helpful advice for actions we can all take to improve our future. Straightforward and clear, the book offers a complete an comprehensive overview of energy in layman's terms, while giving concrete examples of how you can contribute and benefit.

"This book is specific to the field of medical informatics and ubiquitous health care and highlights the use of new trends based on the new initiatives of Web 2.0"--Provided by publisher.

Web 2.0 and Beyond: Principles and Technologies draws on the author's iceberg model of Web 2.0, which places the social Web at the tip of the iceberg underpinned by a framework of technologies and ideas. The author incorporates research from a range of areas, including business, economics, information science, law, media studies, psychology, social
