And Applications To The Human-Computer Interface Michael E. Fotta AT&T Communications 16th FIr. Atrium II, Cincinnati, OH 45202 Artificial intelligence (AI) programs represent knowledge in a fashion similar to human knowledge and the activities of an AI system are closer to human behavior than that of traditional systems. Thus, AI enables the computer to act more like a human instead of making the human think and act more like a computer. This capability combined with applying human factors concepts to the interface can greatly improve the human-computer interface. This paper provides an intro duction to artificial intelligence and then proposes a number of methods for using AI to improve the human-machine inter action. AN INTRODUCTION TO ARTIFICIAL INTELLIGENCE Definition There are many definitions of artificial intelligence (AI) running from the very general to the very detailed. Perhaps the most well accepted general definition is that by Elaine Rich: "Artificial intelligence is the study of how to make computers do things at which, at the moment, people are better," (Rich, 1983). A good example of a detailed definition is provided by the Brattle Research Corporation; "In simplified terms, artificial intelligence works with pattern matching methods which attempt to describe objects, events or pro cesses in terms of their qualitative features and logical and compu tational relationships," (Mishkoff, 1985)."

Blake's Design of Mechanical Joints, Second Edition, is an updated revision of Alexander Blake's authoritative book on mechanical joint and fastener design. This revision brings Blake's 1985 volume up-to-date with modern developments in joint design, and recent technological advances in metallic and non-metallic materials, and in adhesive joining technologies. The book retains Blake's lucid, readable style and his balance of basic concepts with practical applications. Coverage of statistical methods, computational software usage, extensive examples, and a full glossary have been added to make the new edition a comprehensive, practical sourcebook for today's mechanical design engineers.

In the last three or four decades, studies of biomechanics have expanded from simple topical applications of elementary mechanics to entire areas of study. Studies and research in biomechanics now exceed those in basic mechanics itself, underlining the continuing and increasing importance of this area of study. With an emphasis on biodynamic modeling, Fundamentals of Biomechanics provides an accessible, basic understanding of the principles of biomechanics analyses. Following a brief introductory chapter, the book reviews gross human anatomy and basic terminology currently in use. It describes methods of analysis from elementary mathematics to elementary mechanics and goes on to fundamental concepts of the mechanics of materials. It then covers the modeling of biosystems and provides a brief overview of tissue biomechanics. The author then introduces the concepts of biodynamics and human body modeling, looking at the fundamentals of the kinematics, the kinetics, and the inertial properties of human body models. He supplies a more detailed analysis of kinematics, kinetics, and dynamics of these models and discusses the numerical procedures for solving the governing dynamical equations. The book concludes with a review of a few example applications of biodynamic models such as simple lifting, maneuvering in space, walking, swimming, and crash victim simulation. The inclusion of extensive lists of problems of varying difficulty, references, and an extensive bibliography add breadth and depth to the coverage. Focusing on biodynamic modeling to a degree not found in other texts, this book equips readers with the expertise in biomechanics they need for advanced studies, research, and employment in biomedical engineering.

The focus of this book is on centrioles - small organelles adjacent to the nucleus in all human and animal (eucaryotic) cells. It provides the findings and critical analyses of over 750 articles written in this century.In addition to centrioles, the topics include: centrosomes, chromosomes, microtubules and kinetochores, cell division and duplication, and tumor development. The book also includes discussions on centriole dynamics and electromagnetics effects. It concludes with a chapter on centriole errors - particularly cells with supernumerary centrioles.The book is intended for students, scholars, and researchers studying and working in the field of nuclear mechanics. In addition to the book content, it provides a guide for literature investigation.
