• Sommario/riassunto: "Envisioning Socialism examines television and the power it exercised to define the East Germans' view of socialism during the first decades of the German Democratic Republic. In the first book in English to examine this topic, Heather L. Gumbert traces how television became a medium prized for its communicative and entertainment value. She explores the difficulties GDR authorities had defining and executing a clear vision of the society they hoped to establish, and she explains how television helped to stabilize GDR society in a way that ultimately worked against the utopian vision the authorities thought they were cultivating. Gumbert challenges those who would dismiss East German television as a tool of repression that couldn't compete with the West or capture the imagination of East Germans. Instead, she shows how, by the early 1960s, television was a model of the kind of socialist realist art that could appeal to authorities and audiences. Ultimately, this socialist vision was overcome by the challenges that the international market in media products and technologies posed to nation-building in the postwar period. A history of ideas and perceptions examining both real and mediated historical conditions, Envisioning Socialism considers ; television as a technology, an institution, and a medium of social relations and cultural knowledge. The book will be welcomed in undergraduate and graduate courses in German and media history, the history of postwar Socialism, and the history of science and technologies"--

• Sommario/riassunto: This handbook is a definitive guide to the effective use of modern floating-point arithmetic, which has considerably evolved, from the frequently inconsistent floating-point number systems of early computing to the recent IEEE 754-2008 standard. Most of computational mathematics depends on floating-point numbers, and understanding their various implementations will allow readers to develop programs specifically tailored for the standard’s technical features. Algorithms for floating-point arithmetic are presented throughout the book and illustrated where possible by example programs which show how these techniques appear in actual coding and design. The volume itself breaks its core topic into four parts: the basic concepts and history of floating-point arithmetic; methods of analyzing floating-point algorithms and optimizing them; implementations of IEEE 754-2008 in hardware and software; and useful extensions to the standard floating-point system, such as interval arithmetic, double- and triple-word arithmetic, operations on complex numbers, and formal verification of floating-point algorithms. This new edition updates chapters to reflect recent changes to programming languages and compilers and the new prevalence of GPUs in recent years. The revisions also add material on fused multiply-add instruction, and methods of extending the floating-point precision. As supercomputing becomes more common, more numerical engineers will need to use number representation to account for trade-offs between various parameters, such as speed, accuracy, and energy consumption. The Handbook of Floating-Point Arithmetic is designed for students and researchers in numerical analysis, programmers of numerical algorithms, compiler designers, and designers of arithmetic operators. .
