State of the Art in Computer Graphics Aspects of Visualization This is the fourth volume derived from a State of . . . the Art in Computer Graphics Summer Institute. It represents a snapshot of a number of topics in computer graphics, topics which include visualization of scientific data; modeling; some aspects of visualization in virtual reality; and hardware architectures for visu alization. Many papers first present a background introduction to the topic, followed by discussion of current work in the topic. The volume is thus equally suitable for nonspecialists in a particular area, and for the more experienced researcher in the field. It also enables general readers to obtain an acquaintance with a particular topic area sufficient to apply that knowledge in the context of solving current problems. The volume is organized into four chapters - Visualization of Data, Modeling, Virtual Reality Techniques, and Hardware Architectures for Visualization. In the first chapter, Val Watson and Pamela Walatka address the visual aspects of fluid dynamic computations. They discuss algorithms for function-mapped surfaces and cutting planes, isosurfaces, particle traces, and topology extractions. They point out that current visualization systems are limited by low information transfer bandwidth, poor response to viewing and model accuracy modification requests, mismatches between model rendering and human cognitive capabilities, and ineffective interactive tools. However, Watson and Walatka indicate that proposed systems will correct most of these problems.

Today one of the hardest parts of computer aided design or analysis is first modeling the design, then recording and verifying it. For example, a typical vehicle such as a tank, automobile, ship or aircraft might be composed of tens of thousands of individual parts. Many of these parts are composed of cylinders, flats, and simple conic curves and surfaces such as are amenable to modeling using a constructive solid geometry (CSG) approach. However, especially with the increasing use of composite materials, many parts are designed using sculp tured surfaces. A marriage of these two techniques in now critical to continued development of computer aided design and analysis. Further, the graphical user interfaces used in most modeling systems are at best barely adequate to the required task. Critical work on these interfaces is required to continue pushing back the frontiers. Similarly, once the design is modeled, how are the varied and diverse pieces stored, retrieved, and modified? How are physical interferences prevented or eliminated? Although considerable progress has been made, there are still more questions and frustrations than answers. One of the fundamental problems of the 1990s is and will continue to be modeling. The second problem is interpretation. With the ever increasing computational power available, our ability to generate data far exceeds our ability to interpret, understand, and utilize that data.

In the third paper in this chapter, Mike Pratt provides an historical intro duction to solid modeling. He presents the development of the three most freqently used techniques: cellular subdivision, constructive solid modeling and boundary representation. Although each of these techniques devel oped more or less independently, today the designer's needs dictate that a successful system allows access to all of these methods. For example, sculptured surfaces are generally represented using a boundary represen tation. However, the design of a complex vehicle generally dictates that a sculptured surface representation is most efficient for the 'skin' while constructive solid geometry representation is most efficent for the inter nal mechanism. Pratt also discusses the emerging concept of design by 'feature line'. Finally, he addresses the very important problem of data exchange between solid modeling systems and the progress that is being made towards developing an international standard. With the advent of reasonably low cost scientific workstations with rea sonable to outstanding graphics capabilities, scientists and engineers are increasingly turning to computer analysis for answers to fundamental ques tions and to computer graphics for present~tion of those answers. Although the current crop of workstations exhibit quite impressive computational ca pability, they are still not capable of solving many problems in a reasonable time frame, e. g. , executing computational fluid dynamics and finite element codes or generating complex ray traced or radiosity based images.

Rubor (redness), tumor (swelling), calor (heat), and dolor (pain) are the classical signs of inflammation. These features are obvious in the skin, where injury or disease causes flare, wheal, and painful burning sensations. Vasodi- tation underlies the flare and heat, plasma exudation the swelling, and acti- tion of sensory nerves relays pain. In chronic conditions, skin biopsies show inflammatory cell infiltrate. Inflammation is not unique to the skin and contr- utes to disease and repair processes in other organ systems in the body. From the viewpoint of this volume, lung inflammation is now recognized as central to the pathophysiology of a number of severe respiratory conditions, the two most common being asthma and chronic obstructive pulmonary disease (COPD). In asthma, and to a lesser extent COPD, there is evidence of vasodilatation, with congestion of blood vessels accompanied by reddening of the airway mucosa, and of plasma exudation, leading to swelling of the airway wall. Similarly, although less pronounced than in the skin, there is evidence of pain, for example, the - pleasant chest sensations associated with asthma attacks. Understanding the pat- genesis of airway inflammation will enable rational design of drugs to effectively treat conditions such as asthma and COPD. However, whereas immediate access to the skin facilitates investigation of disease processes, the lung, although "open to atmosphere," is much less accessible. Consequently, the investigation of lung inflammation is usually indirect. Thus, a wide variety of research techniques are used.

The latest from a computer graphics pioneer, An Introduction to NURBS is the ideal resource for anyone seeking a theoretical and practical understanding of these very important curves and surfaces. Beginning with Bezier curves, the book develops a lucid explanation of NURBS curves, then does the same for surfaces, consistently stressing important shape design properties and the capabilities of each curve and surface type. Throughout, it relies heavily on illustrations and fully worked examples that will help you grasp key NURBS concepts and deftly apply them in your work. Supplementing the lucid, point-by-point instructions are illuminating accounts of the history of NURBS, written by some of its most prominent figures.

Global problems require global information, which satellites can now provide. With ever more sophisticated control methods being developed for infectious diseases, our ability to map spatial and temporal variation in risk is more important than ever. Only then may we plan control campaigns and deliver novel interventions and remedies where the need is greatest, and sustainable success is most likely. This book presents a comprehensive guide to using the very latest methods of surveillance from satellites, including analysing spatial data within geographical information systems, interpreting complex biological patterns, and predicting risk both today and as it may change in the future. Of all infectious disease systems, those that involve free-living invertebrate vectors or intermediate hosts are most susceptible to changing environmental conditions, and have hitherto received most attention from the marriage of analytical biology with this new space technology. Accordingly, this volume presents detailed case studies on malaria, African trypanosomiasis (sleeping sickness), tick-borne infections and helminths (worms). For those who are unfamiliar with this science, and unsure how to start, the book ends with a chapter of practical advice on where to seek hands-on instruction. The lessons to be learned from these studies are applicable to many other epidemiological and ecological problems that face us today, most significantly the preservation of the world's biodiversity.

In this volume, first published in 1983, Professor Rogers examines the usefulness of a phenomenological approach to sociology. Her broad purpose is to demonstrate the theoretical and methodological advantages phenomenological sociology holds. Thus she offers a selective, introductory exposition of phenomenology, highlighting its relevance for social scientists and undercutting the notion of phenomenology as a non-scientific, subjective, or esoteric method of study.

Anup Shah and Fiona Rogers have spent much of the last decade in the company of the world-famous chimpanzees of Tanzania's Gombe National Park, getting to know their characters and learning about the intricacies of their lives. Tales from Gombe provides an unparalled insight into their world. Through endearing stories and stunningly intimate photography, it tells the story of their lives, an epic saga full of convoluted plots, family alliances, intrigue, love, passion, suffering, ambition, politics, puzzles, surprises and controversies. The chimpanzees of Tanzania's Gombe National Park are probably the most famous group of wild animals in history, having been observed and chronicled for more than 50 years. Through studies initiated by the palaeontologist and anthropologist Louis Leakey and carried out by the primatologist Dr Jane Goodall, people worldwide know some of their names and stories. In Tales from Gombe Anup Shah and Fiona Rogers introduce us to all the different characters in this unique family, from the bold and mischievous Google and the powerful Titan to the enigmatic Freud.They tell the dramatic story of this unusual society, describing all that has happened since they started studying them, while beautifully capturing the daily interactions of the various characters. The combination of breathtaking photography and rich social history provides the reader with a thought-provoking experience and evokes a strong sense of empathy and respect for chimpanzees. Highly captivating and often deeply moving, Tales from Gombe will inspire all those who read it to learn more about our closest cousins.

Erving Goffman (1922-82) was arguably one of the most influential American sociologists of the twentieth century. A keen observer of the interaction order of everyday life, Goffman's books, which have sold in the hundreds of thousands, continue to be widely read and his concepts have permanently entered the sociology lexicon. This volume consists of twelve original essays, all written by prominent Goffman scholars, that critically assess Goffman's many contributions to various areas of study, including functionalism, social psychology, ethnomethodology, and feminist theory.

The unsettling language of blood has been invoked throughout the history of Christianity. But until now there has been no truly sustained treatment of how Christians use blood to think with. Eugene F. Rogers Jr. discusses in his much-anticipated new book the sheer, surprising strangeness of Christian blood-talk, exploring the many and varied ways in which it offers a language where Christians cooperate, sacrifice, grow and disagree. He asks too how it is that blood-talk dominates when other explanations would do, and how blood seeps into places where it seems hardly to belong. Reaching beyond academic disputes, to consider how religious debates fuel civil ones, he shows that it is not only theologians or clergy who engage in blood-talk, but also lawmakers, judges, generals, doctors and voters at large. Religious arguments have significant societal consequences, Rogers contends; and for that reason secular citizens must do their best to understand them.
