This unique text, for both the first year graduate student and the newcomer to the field, provides in-depth coverage of the basic principles of data communications and covers material which is not treated in other texts, including phase and timing recovery and echo cancellation. Throughout the book, exercises and applications illustrate the material while up-to-date references round out the work.

Following three printings of the First Edition (1978), the publisher has asked for a Second Edition to bring the contents up to date. In doing so the authors aim to show how the newer microscopies are related to the older types with respect to theoretical resolving power (what you pay for) and resolution (what you get). The book is an introduction to students, technicians, technologists, and scientists in biology, medicine, science, and engineering. It should be useful in academic and industrial research, consulting, and forensics; how ever, the book is not intended to be encyclopedic. The...

Solidly founded on 25 years of research and teaching, the author integrates the salient features of the subdisciplines of computer science into a comprehensive conceptual framework for the design of human-computer interfaces. He combines definitions, models, taxonomies, structures, and techniques with extensive references and citations to provide professors and students of all levels with a text and practical reference.

A companion to the author's User Interface Evaluation, this book details a systematic and comprehensive methodology to measure and evaluate new or existing human-computer interfaces. The text will serve both as a reference source, and as a supplement to its sister volume.

This book is intended as both an introduction to the state-of-the-art in visual languages, as well as an exposition of the frontiers of research in advanced visual languages. It is for computer scientists, computer engi neers, information scientists, application programmers, and technical managers responsible for software development projects who are inter ested in the methodology and manifold applications of visual languages and visual programming. The contents of this book are drawn from invited papers, as well as selected papers from two workshops: the 1985 IEEE Workshop on Lan guages for...

Many hardware devices present either results or alternatives selected by computers to users. A few are video display terminals (VDTs), touch-tone telephones, and computer-generated speech systems. In part this book con cerns the impact and implications of such tools. Alternatively this is an attempt to provide material for researchers, students, and managers con cerned with computer interfaces. The subject of computer interfaces is at one level a technical subarea sharing common interests with the broad dis ciplines of computer science, psychology, and bioengineering. However, it is also a...

The interface between the user of a computer-based information system and the system itself has been evolving at a rapid rate. The use of a video screen, with its color and graphics capabilities, has been one factor in this evolution. The development of light pens, mice, and other screen image manipulation devices has been another. With these capabilities has come a natural desire to find more effective ways to make use of them. In particular, much work has gone into the development of interface systems that add visual elements such as icons and graphics to text. The desire to use these...
