This book was written with the novice or intermediate 8052 developer in mind. Assuming no prior knowledge of the 8052, it takes the reader step-by-step through the architecture, including discussions and explanations of concepts, such as internal RAM, external RAM, Special Function Registers (SFRs), addressing modes, timers, serial I/O, and interrupts. This is followed by an in-depth section on assembly language, which explains each instruction in the 8052 instruction set, as well as related concepts, such as assembly language syntax, expressions, assembly language directives, and how to implement 16-bit mathematical functions. The book continues with a thorough explanation of the 8052 hardware itself, reviewing the function of each pin on the microcontroller and follows this with the design and explanation of a fully functional single board computer - every section of the schematic design is explained in detail to provide the reader with a full understanding of how everything is connected, and why. in which the reader will learn about the SBCMON monitor program for use on the single board computer, interfacing with a 4x4 keypad, communicating with a 16x2 LCD in direct-connect, as well as memory-mapped fashion, utilizing an external serial EEPROM via the SPI protocol, and using the I2C communication standard to access an external real time clock. The book takes the reader with absolutely no knowledge of the 8052 and provides him with the information necessary to understand the architecture, design and build a functioning circuit based on the 8052, and write software to operate the 8052 in assembly language.

This text is intended as a guide to OpenVMS performance management and application design. It features a variety of performance-related topics, and guidelines are given, with examples on how to relieve specific problems It features tuning tips on RDBMs (Oracle, Ingres, and Rdb) and making changes to Sysgen parameters, and specific application tuning (All-in-1, Pathworks, X-Windows and TCP/IP). It covers tuning methodologies, contains information on a range of performance-related topics, and provides information on "rules of thumb" on CPU, memory and disk I/O management. It also covers versions 5.0 and 6.0 of VMS.

Die Unified Modeling Language (UML) hat sich zur dominanten Modellierungssprache entwickelt, "agile" Methoden werden inzwischen bei vielen Softwareentwicklungen eingesetzt. In dem Buch wird ein Ansatz vorgestellt, der UML mit Elementen agiler Methoden kombiniert und deshalb fur den Einsatz in Anwendungsdomanen besonders geeignet ist. Die 2. Auflage wurde durchgehend uberarbeitet und basiert auf UML 2.3 sowie der Java-Version 6. Auf der Internetseite http: //www.se-rwth.de/mbse ist weiterfuhrendes Material bereitgestellt.

The Committee on the Future of Supercomputing was tasked to assess prospects for supercomputing technology research and development in support of U.S. needs, to examine key elements of context--the history of supercomputing, the erosion of research investment, the changing nature of problems demanding supercomputing, and the needs of government agencies for supercomputing capabilities--and to assess options for progress. This interim report establishes context--including the history and current state of supercomputing, application requirements, technology evolution, the socioeconomic context--to identify some of the issues that may be explored in more depth in the second phase of the study.

Written especially for programmers adopting a free-format style, this manual explores the role of functions in writing RPG IV programs. Demonstrating the potential of functions, many topics are explored such as details about existing RPG IV built-in functions, writing new functions, using ILE concepts to use C functions, and utilizing IBM API's functions. Explaining how to write small programs, either as sub-procedures or modules, and how to gather those parts together to make programs that are easy to write and maintain, this is a natural next step for programmers familiar with a free-format style of coding.

Join the more than 150,000 programmers who have learned CICS using CICS books alone. Now, the two-part CICS for the COBOL Programmer has been revised into a single volume that meets today's need for fast-paced training. Readers get all the commands and features that are current today--plus, new chapters on creating web or component-based programs--in just 630, information-packed pages.

One critical barrier leading to successful implementation of flexible manufacturing and related automated systems is the ever-increasing complexity of their modeling, analysis, simulation, and control. Research and development over the last three decades has provided new theory and graphical tools based on Petri nets and related concepts for the design of such systems. The purpose of this book is to introduce a set of Petri-net-based tools and methods to address a variety of problems associated with the design and implementation of flexible manufacturing systems (FMSs), with several implementation examples.There are three ways this book will directly benefit readers. First, the book will allow engineers and managers who are responsible for the design and implementation of modern manufacturing systems to evaluate Petri nets for applications in their work. Second, it will provide sufficient breadth and depth to allow development of Petri-net-based industrial applications. Third, it will allow the basic Petri net material to be taught to industrial practitioners, students, and academic researchers much more efficiently. This will foster further research and applications of Petri nets in aiding the successful implementation of advanced manufacturing systems.

Second Generation Mainframes: The IBM 7000 Series describes IBM's second generation of mainframe computers which introduced new technology, new peripherals and advanced software. These systems were continuations of the instruction sets of the IBM 700 series with significant enhancements, but supported upwards compatibility that preserved customers' investment in the earlier series. The use of magnetic cores, fast magnetic tapes and disks, and transistors yielded computation speeds that opened new domains for computation. Programming languages continued to be developed and enhanced, and new ones were developed for specific domains, such as SNOBOL, COBOL, and Macro Assemblers. Robust subroutine libraries for mathematical applications appeared. New operating systems provided many capabilities to programmers for data management and file systems, limited multiprocessing, timesharing, programming language support, and better error handling and control of peripherals. Early concepts in persistent file systems on magnetic disks were developed that changed the nature of job processing. The IBM 7000 series led the way in many innovative concepts that helped to establish IBM as the foremost manufacturer of computer systems. However, the diversity of the models put significant strain on IBM's financial resources and development teams, which ultimately led to OBM's development of the System/360 family of machines.
