The logic and methodology of design is examined in this book from the perspective of computer science. Computers provide the context for this examination both by discussion of the design process for hardware and software systems and by consideration of the role of computers in design in general. The central question posed by the author is whether or not we can construct a theory of design. This book concentrates upon the relationship between design, mathematics and science and thus its audience must include designers and software designers as well as computer scientists.

Planning algorithms are impacting technical disciplines and industries around the world, including robotics, computer-aided design, manufacturing, computer graphics, aerospace applications, drug design, and protein folding. This coherent and comprehensive book unifies material from several sources, including robotics, control theory, artificial intelligence, and algorithms. The treatment is centered on robot motion planning, but integrates material on planning in discrete spaces. A major part of the book is devoted to planning under uncertainty, including decision theory, Markov decision processes, and information spaces, which are the 'configuration spaces' of all sensor-based planning problems. The last part of the book delves into planning under differential constraints that arise when automating the motions of virtually any mechanical system. This text and reference is intended for students, engineers, and researchers in robotics, artificial intelligence, and control theory as well

Technology in Action

出版日:2000/06/22 作者:Christian Heath  出版社:Cambridge Univ Pr  裝訂:平裝
Despite the extraordinary advances in digital and communication technology over recent years, we know very little about the way these complex systems affect everyday work and interaction. This book seeks to explore these issues through a series of video-based field studies. It begins by discussing the introduction of basic information systems in general medical practice and ends with an exploration of interpersonal communication in advanced media spaces; in the process also looking at news production, the control room of London Underground and computer aided design in architectural practice. Social interaction forms a particular focus of these studies as they explore the way individuals use various tools and technologies and coordinate their actions and activities with each other. The authors also show how video-based field studies of work and interaction can inform the design, development and deployment of new technology, in this valuable new resource for academics, researchers and pr

Design Analysis:Mathematical Modeling of Nonlinear Systems
90 折
出版日:1999/01/13 作者:David E. Thompson  出版社:Cambridge Univ Pr  裝訂:精裝
An integral part of engineering design is the development of models that describe physical behavior or phenomena in mathematical terms. As engineering systems have become more complex, classic linear methods of modeling and analysis have proved inadequate, creating a need for nonlinear models to solve design problems. This 1999 text provides an introduction to mathematical modeling of linear and nonlinear systems, with an emphasis on the solution of nonlinear design problems. While encouraging the use of the computer as a tool for modeling and analysis, the aim is to discuss the basic concepts underlying computer techniques and to seek analytical solutions. Among topics covered are exact solution, numerical solution, graphical solution, and approximate solution methods; and the stability of nonlinear systems. Numerous examples show how to apply modeling methods to real engineering systems. The book also includes end-of-chapter problems and case studies of challenging design problems. I

The Art and Science of Optical Design is a comprehensive introduction to lens design, covering the fundamental physical principles and key engineering issues. Several practical examples of modern computer-aided lens design are worked out in detail from start to finish. The basic theory and results of optics are presented early on in the book, along with a discussion of optical materials. Aberrations, and their correction, and image analysis are then covered in great detail. Subsequent chapters deal with design optimisation and tolerance analysis. Several design examples are then given, beginning with basic lens design forms, and progressing to advanced systems, such as gradient index and diffractive optical components. In covering all aspects of optical design, including the use of modern lens design software, this book will be invaluable to students of optical engineering as well as to anyone engaged in optical design at any stage.

A teen social media star learns he can't control everything in this delicious, queer graphic novel adaptation that relocates Jane Austen's Emma to a modern-day high school in Queens, New York. Evan Horowitz has it all: beauty, brains, and a not-so-secret flair for matchmaking! An Insta influencer with a talent for makeup and a taste for romance, he's no stranger to playing cupid for those hopelessly clueless in finding love. So when shy transfer student Natalia shuffles into school one day, Evan can't help but get his hands messy! With so many matches to choose from, it's not long before he sets a plan in motion for Natalia--much against the better judgement of his level-headed best friend, Davi. But he takes things too far, creating a web of drama that spirals out of his control. Can Evan learn to put the people closest to him before his misguided ambition? Or will he lose them and his own chance at romance, too?
