Most suitable application of this new field is to the specification, design and implementation of computer systems which continuously act and interact with their environment.

    The first edition of Advanced UNIX Programming is still used and considered to be a must have book on any UNIX programmer's shelf. With this new edition UNIX programmers now have a one-volume, comprehensive, in-depth guide to the essential system-level services provided to them by the UNIX family of operating systems - now including Linux, FreeBSD, and the Mac OS X kernel (Darwin). All UNIX application programs, regardless of what language they are written in, run on top of these services, so mastering them is essential for successful UNIX programming. And, with a movement towards open-source systems, programmers will appreciate the book's emphasis on portability.

    Found in a diverse range of machines such as clocks, typewriters, automatic draughting machines, numerically controlled machine tools, and computer peripherals, stepping motors offer easy compatibility with digital equipment and ease of control. This thoroughly updated second edition of Stepping Motors offers a practical approach to the subject and relates the workings, design, and construction of these motors to underlying electromagnetic principles. The reader is taken through a brief history of stepping-motor development and is provided with expert treatments of the theory, terminology, control systems, and likely applications associated with the devices. The text is copiously illustrated with clear and helpful diagrams and contains much detailed information. It is the perfect introduction for students and professionals in electrical and electronic engineering.

    

    This book addresses central issues in concurrency, and by producing both a syntactic definition and a denotational model of Hewitt's actor paradigm--a model of computation specifically aimed at constructing and analyzing distributed large-scale parallel systems--it substantially advances the understanding of parallel computation.Contents: Introduction. General Design Decisions. Computation in ACTOR Systems. A More Expressive Language. A Model for ACTOR Systems. Concurrency Issues. Abstraction and Compositionality. Conclusions.

    This text accurately treats the parametric geometry of curves, surfaces and solids, the construction of geometric models and the analytical techniques that can be used and applications. Extensive use is made of end-of-chapter problems.

    

    In addition, it gives a historical review from the origins of computer art to current developments.
