Service-oriented architectures provide high levels of inter-operability and high means of adaptability. Nevertheless, distributed service-based business processes demand for robust, flexible and - bearing scalability in mind - efficient security mechanisms. This book presents access control models and procedures for intra- and inter-organizational service compositions. It introduces a framework for distributed access control in Web service federations and highlights optimizations through the consolidation of security policies and the caching of access control information. In combination, these concepts enable efficient and reliable access control for current and upcoming service-oriented architectures. As the presented techniques build up on prevalent security standards like WS-Security and XACML, application developers, system designers, and security experts will be able to seamlessly transfer them to their particular Web service-based projects.

From ancient stadium construction to a design object of the twenty-first century, sports arenas have long been turned into places hosting a global media spectacle. For a few hours or days, colossuses made of steel and concrete transform into colourful festival locations. Since the first ancient stadium in Greek Olympia, the typology of stadium construction has undergone a profound transformation: due to changes in requirements and demand, an urban entertainment centre has emerged from the simple running track in the countryside. Through selected examples of projects, this volume from the Construction and Design Manual series illustrates the development of stadiums in relation to building typologies. It provides a basic manual of stadium design using basic planning parameters. Examined are, amongst others, Olympic stadiums, football stadiums, velodromes and ice arenas. Drawings, detailed plans and large-format photos facilitate an understanding of the carefully selected examples and are used to analyse stadium construction in terms of its history, planning and architecture.

Clockwork Liza
Star and Artist: The Career Achievement of Liza Minnelli
Actress, singer, musical theater star, gay Liza Minnelli. Always citing the past but acting in present, her image is an oddity of the entertainment industry. Private background and acting roles flow together in the case of Minnelli, who was born into the American show business in 1946. But she is more than Cabaret, Great American Songbook, Broadway and drag model. This book is neither another sentimental biography of her so-called tragic private life nor a pure scientific examination. It simply aims to analyze her single fields of work in theater, film, television, recording studio and on concert stage, which all perform together like a clockwork.
