The Mathematical Structure of Raster Graphics presents a mathematical characterization of the structure of raster graphics, a popular and diverse form of computer graphics. The semantics and theory of the mathematical structure of raster graphics are discussed. Notations that help to clarify some of the concepts generally considered to be fundamental to computer graphics are included. Comprised of seven chapters, this book begins with a description of a general framework for specifying and manipulating scenes. Basic graphic entities, called primitive graphic objects, are defined using a simple notation over a Euclidean space. The reader is then introduced to a semantics of visibility; a mathematical semantics of rendering, developed using the very basic notion of measure; and a mathematical formalization of bit-mapped graphics. A framework for specifying illumination models is also described, along with the complexity of abstract ray tracing. This monograph will be a useful resource for undergraduate and graduate students, researchers, and practitioners in the fields of mathematics and computer graphics, and to those with some basic computer graphics background.
This is a story of belief, disillusionment and atonement. Long identified with leftist causes, the journalist Eugene Lyons was by background and sentiment predisposed to early support of the Russian Revolution. A "friendly correspondent," he was one of a coterie of foreign journalists permitted into the Soviet Union during the Stalinist era because their desire to serve the revolution was thought to outweigh their desire to serve the truth. Lyons first went to the Soviet Union in 1927, and spent six years there. He was there as Stalin consolidated his power, through collectivization and its consequences, as the cultural and technical intelligentsia succumbed to the secret police, and as the mechanisms of terror were honed. As Ellen Frankel Paul notes in her major new introduction to this edition, "It was this murderous reality that Stalin's censors worked so assiduously to camouflage, corralling foreign correspondents as their often willing allies." Lyons was one of those allies. Assignment in "Utopia "describes why he refused to see the obvious, the forces that kept him from writing the truth, and the tortuous path he traveled in liberating himself. His story helps us understand how so many who were in a position to know were so silent for so long. In addition, it is a document, by an on-the-scene journalist, of major events in the critical period of the first Five-Year Plan. As Ellen Frankel Paul notes in her major new introduction to this new edition, Assignment in "Utopia "is particularly timely. The system it dissects in such devastating detail is in the process of being rejected throughout Eastern Europe and is under challenge in the Soviet Union itself. The book lends insight into the "political pilgrim" phenomenon described by Paul Hollander, in which visitors celebrate terrorist regimes, seemingly oblivious to their destructive force. The book is valuable for those interested in the Stalinist era in the Soviet Union, those interested in radical regimes and political change, as well as those interested in better understanding current events in Europe. It will also be useful for the tough questions it poses about journalistic ethics.
With more than 5,000 works cited, Handbook of Avian Hybrids of the World is the greatest compendium of information ever published on hybridization in birds. Worldwide in scope, it provides information on all reported avian crosses, not only those occurring in captivity, but also in a natural setting (approximately 4,000 crosses are covered). This book is a basic reference, intended both for the serious birder and the professional biologist. McCarthy's work fills a need for reference material that takes into account the last half century of data. It will be of interest to workers in a wide variety of fields, ranging from animal behavior to genetics, ecology, zoology, and systematics. In fact, it will make fascinating reading for anyone interested in birds and the natural world.
Heimler (1922-1990, born in Szombathely) describes his deportation from Hungary, and his experiences in Auschwitz and in Buchenwald (and its associated labor camps Tröglitz and Berga-Elster). In Berga-Elster he became responsible for a group of children who spontaneously gathered around him. They set out together on the death march in the direction of Mauthausen, and escaped.
Argues that the security of the United States cannot be protected by reducing its involvement in international affairs. The book contends that the most vital security interest of the nation is in the effective functioning of the state system as a system of peace.
In this work, Eugene Narmour extends the unique theories of musical perception presented in The Analysis and Cognition of Basic Melodic Structures. The two books together constitute the first comprehensive theory of melody founded on psychological research. Narmour's earlier study dealt with cognitive relations between melodic tones at their most basic level. After summarizing the formalized methodology of the theory described in that work, Narmour develops an elaborate and original symbology to show how sixteen archetypes can combine to form some 200 complex structures that, in turn, can chain together in a theoretically infinite number of ways. He then explains and speculates on the cognitive operations by which listeners assimilate and ultimately encode these complex melodic structures. More than 250 musical examples from different historical periods and non-Western cultures demonstrate the panstylistic scope of Narmour's model. Of particular importance to music theorists and music historians is Narmour's argument that melodic analysis and formal analysis, though often treated separately, are in fact indissolubly linked. The Analysis and Cognition of Melodic Complexity will also appeal to ethnomusicologists, psychologists, and cognitive scientists.
This down-to-earth introduction to computation makes use of the broad array of techniques available in the modern computing environment. A self-contained guide for engineers and other users of computational methods, it has been successfully adopted as a text in teaching the next generation of mathematicians and computer graphics majors.
The harsh Armistice terms of 1918, the short-lived Weimar Republic, Hindenburg's senile vacillations, and behind-the-scene power plays form the backbone of this excellent study covering German history during the first three-and-a-half decades of the century."--Publishers website.
