Computer graphics, computer-aided design, and computer-aided manufacturing are tools that have become indispensable to a wide array of activities in contemporary society. Euclidean processing provides the basis for these computer-aided design systems although it contains elements that inevitably lead to an inaccurate, non-robust, and complex system. The primary cause of the deficiencies of Euclidean processing is the division operation, which becomes necessary if an n-space problem is to be processed in n-space. The difficulties that accompany the division operation may be avoided if processing is conducted entirely in (n+1)-space. The paradigm attained through the logical extension of this approach, totally four-dimensional processing, is the subject of this book. This book offers a new system of geometric processing techniques that attain accurate, robust, and compact computations, and allow the construction of a systematically structured CAD system.
Computer Control and Human Error presents accounts of various incidents at computer-controlled plants. These incidents include equipment and software faults; treating the computer as a "black box"; misjudging the way operators respond to the computer; errors in the data entry; failure to inform operators of changes in data or programs; and unauthorized interference with peripheral equipment. The discussion then turns to the use of hazard and operability studies (Hazops) to prevent or reduce errors in computer-controlled plants. The book describes the conventional Hazop as used in the process industry and an overview of the different Chazop frameworks/guidelines suggested by engineers and researchers. It then presents new Chazop methodology which is based on incident analysis. The final chapter presents reasons for failures in computerized systems, each of which is illustrated with an example. Most of the examples did not cause an actual safety problem, simply because they occurred within systems that are not safety-related. Some of these examples appear in the literature; others are from personal experience or from private communications.
This new networking text follows a top-down approach. The presentation begins with an explanation of the application layer, which makes it easier for students to understand how network devices work, and then, with the students fully engaged, the authors move on to discuss the other layers, ending with the physical layer. With this top-down approach, its thorough treatment of the topic, and a host of pedagogical features, this new networking book offers the market something it hasn't had for many years- a well-crafted, modern text that places the student at the center of the learning experience.
Forouzan's Computer Networks presents a complex topic in an accessible, student-friendly way that makes learning the material not only manageable but fun as well. The appealing visual layout combines with numerous figures and examples to provide multiple routes to understanding. Students are presented with the most up-to-date material currently available and are encouraged to view what they are learning in a real-world context. This approach is both motivating and practical in that students begin to see themselves as the professionals they will soon become.
ETHICS IN THE MELTING-POT Jack Mahoney & Elizabeth Vallance Professor Jack Mahoney is Director of the King's College Business Ethics Research Centre, University of London, and Elizabeth Vallance is Visiting Professor in Politics at Queen Mary and Westfield College, University of London. AT lHE START of this century Israel Zangwill wrote of 'the great Melting Pot where all the races of Europe are melting and reforming'. He was, of course, writing about the USA and had the American immigration experience in mind; but today one need not cross the Atlantic to see Europe as a melting-pot and its members in a state of profound flux and mutation. In Western Europe, what began in mid-century as a largely Franco German attempt to prevent a recurrence of European war, by identifying and creating a common industrial policy in coal and steel, evolved by degrees into an industrial alliance of western European nations and the creation of a Single European Market. Originally six, then ten, and currently twelve, the number of member states of the European Economic Community, more recently the European Community, is still on the increase, as new countries apply to join and others consider a future approach.
One service mathematics has rendered the human race. It has put common sense back where it belongs. It has put common sense back where it belongs, on the topmost shelf next to the dusty canister labelled discarded nonsense. Eric TBell Every picture tells a story. Advenisement for for Sloan's backache and kidney oils, 1907 The book you have in your hands as you are reading this, is a text on3-dimensional topology. It can serve as a pretty comprehensive text book on the subject. On the other hand, it frequently gets to the frontiers of current research in the topic. If pressed, I would initially classify it as a monograph, but, thanks to the over three hundred illustrations of the geometrical ideas involved, as a rather accessible one, and hence suitable for advanced classes. The style is somewhat informal; more or less like orally presented lectures, and the illustrations more than make up for all the visual aids and handwaving one has at one's command during an actual presentation.
