"More concretely," the authors explain, "it is the controlled manipulation of mathematical formulas, using a collection of techniques for solving problems."

    In 1985, a new version of the language was developed, incorporating additional features such as multiple input files, dynamic regular expressions, and user-defined functions. This new version is available for both Unix and MS-DOS. This is the first book on AWK. It begins with a tutorial that shows how easy AWK is to use. The tutorial is followed by a comprehensive manual for the new version of AWK. Subsequent chapters illustrate the language by a range of useful applications, such as: Retrieving, transforming, reducing, and validating data Managing small, personal databases Text processing Little languages Experimenting with algorithms The examples illustrates the books three themes: showing how to use AWK well, demonstrating AWKs versatility, and explaining how common computing operations are done. In addition, the book contains two appendixes: summary of the language, and answers to selected exercises.

    In a self-contained manner it proceeds from mathematical and theoretical considerations to actual practical computer routines. With over 100 new routines bringing the total to well over 300, plus upgraded versions of the original routines, the new edition remains the most practical, comprehensive handbook of scientific computing available today.

    Discover how the basic TCP/IP technology has survived and evolved over two decades of exponential growth, and understand the TCP/IP protocols and technical advances. This edition explains emerging technologies such as Mobile IP, Virtual Private Networks, resource reservation with RSVP, and Ipv6. Comer reveals how to master TCP/IP and how the Internet works. The reader is required to have a modest background in the fundamentals of computer systems, but does not need sophisticated mathematics. As with previous editions, this edition provides an introduction to physical networks and then shows how they are combined to form an internet. It states design principles clearly, and discusses motivations and consequences. THIS NEW EDITION OF VOLUME 1: *Explains how voice and video are sent over IP internets and how IP Telephony operates *Describes Mobile IP (a technology that allows a computer to move fr

    The author provides a coherent explication of probability as a language for reasoning with partial belief and offers a unifying perspective on other AI approaches to uncertainty, such as the Dempster-Shafer formalism, truth maintenance systems, and nonmonotonic logic.The author distinguishes syntactic and semantic approaches to uncertainty--and offers techniques, based on belief networks, that provide a mechanism for making semantics-based systems operational. Specifically, network-propagation techniques serve as a mechanism for combining the theoretical coherence of probability theory with modern demands of reasoning-systems technology: modular declarative inputs, conceptually meaningful inferences, and parallel distributed computation. Application areas include diagnosis, forecasting, image interpretation, multi-sensor fusion, decision support systems, plan recognition, planning, speech recognition--in short, almost every task requiring that conclusions be drawn from uncertain clues and incomplete information.Probabilistic Reasoning in Intelligent Systems will be of special interest to scholars and researchers in AI, decision theory, statistics, logic, philosophy, cognitive psychology, and the management sciences. Professionals in the areas of knowledge-based systems, operations research, engineering, and statistics will find theoretical and computational tools of immediate practical use. The book can also be used as an excellent text for graduate-level courses in AI, operations research, or applied probability.

    Covers specialized data structures, and explains how to choose the appropriate algorithm or data structure for the job at hand. The four sections treat primary file organizations, bit level and related structures, tree structures, and file sorting. Opening chapters cover sequential file organization, direct file organization, indexed sequential file organization, bits of information, secondary key retrieval, and bits and hashing. Following chapters cover binary tree structures, B-trees and derivatives, hashing techniques for expandable files, other tree structures, more on secondary key retrieval, sorting, and applying file structures. Contains pseudocode, or an outline in English, for most algorithms. Includes end-of-section questions, with answers to some. Extensively illustrated.

    It provides a specification for the KornShell language, tutorial material for those new to ksh (the program that implements the KornShell language), and a comprehensive reference for all ksh users. Covers major new additions to the KornShell language ksh93 (including command completion and a key binding mechanism); provides tutorials for both of the functions of ksh (as an interactive command language, and as a programming language); contains numerous examples illustrating the features of ksh; and features a Quick Reference summary of the KornShell language with page references to the book. For both new users with little shell experience, and for experienced computer users who are familiar with ksh and/or other shells. ISBN of 1st Edition: 0-13-516972-02.

    Its primary market is in electrical engineering,although the course is also taught in computer science departments. A major feature of the text is that it covers both performance analysis and implementation considerations.

    

    There are new chapters on program optimisation, abstract datatypes in a functional setting, and programming in a monadic style. There are complete new case studies, and many new exercises. As in the first edition, there is an emphasis on the fundamental techniques for reasoning about functional programs, and for deriving them systematically from their specifications. The book is self-contained, assuming no prior knowledge of programming and is suitable as an introductory undergraduate text for first- or second-year students.

    

    These techniques deal with real programs and they are realistically illustrated, using the C and Awk languages. Bentley also provides the reader with some tricks of the programmer's trade, like a collection of rules of thumb and hints for finding simple solutions to hard problems.These essays also originally appeared in the author's column in Communication of the ACM, and have been substantially revised, incorporating new sections, problems, and reader comments.

    It includes technical data, quick reference charts and Norton's characteristically astute insights and covers a range of new topics as well as new information on previously covered topics.New topics include: the 80286 and 80386 microprocessors, the enhanced keyboard, the new VGA and MCGA, the new PS/2 ROM BIOS and all current versions of PC-DOS.

    First five chapters provide rapid familiarization with the unique aspects of the IBM terminal device family, logging on and off, the ISPF main menu, and the initial set-up often needed for new accounts. This part of the book can be assimilated in a few hours. Latter five chapters are arranged with examples of the most common way ISO/ISPF is used: for composition of program language code, and composition and submission of job control language to process it. The reader can progress through these chapters performing these processes hands-on, in a self-paced tutorial manner. Reference charts and examples depict a natural flow of the job editing and job submission work.

    

    Includes two 5 1/4" DS/DD diskettes for IBM PCs and compatibles

    Focusing on the new R4000 and R6000 chips, this book is organized into two major sections: Chapters 1 through 6 describe the characteristics of the CPU, while Chapter 7 through 9 describe the Floating Point Unit (FPU). This book describes the general characteristics and capabilities of each RISC processor, along with a description of the programming model, memory management unit (MMU), and the registers associated with each processor. Also included is an overview of the underlying concepts that distinguish RISC architecture from Complex Instruction Set Computer (CISC) architecture.
