    书名:基本商业程序的建模 Essential Business Process Modeling (Paperback) 作者: Mike Havey 出版商:O Reilly 1 edition (August 18, 2005) 内容介绍: Ten years ago, groupware bundled with email and calendar applications helped track the flow of work from person to person within an organization. Workflow in today s enterprise means more monitoring and orchestrating massive systems. A new technology called Business Process Management, or BPM, helps software architects and developers design, code, run, administer, and monitor complex network-based business processes. BPM replaces those sketchy flowchart diagrams that business analysts draw on whiteboards with a precise model that uses standard graphical and XML representations, and an architecture that allows it converse with other services, systems, and users.

    The ability to write efficient, high-speed arithmetic routines ultimately depends upon your knowledge of the elements of arithmetic as they exist on a computer. That conclusion and this book are the result of a long and frustrating search for information on writing arithmetic routines for real-time embedded systems. With instruction cycle times coming down and clock rates going up, it would seem that speed is not a problem in writing fast routines. In addition, math coprocessors are becoming more popular and less expensive than ever before and are readily available. These factors make arithmetic easier and faster to use and implement. However, for many of you the systems that you are working on do not include the latest chips or the faster processors. Some of the most widely used microcontrollers used today are not Digital Signal Processors (DSP), but simple eight-bit controllers such as the Intel 8051 or 8048 microprocessors.

    There are many different (and often confusing) terms associated with clock-based devices. This application note attempts to clarify these terms, and hence serves as a comprehensive reference on clock terminology. This application note can be divided into two sections. The first section describes and distinguishes between various clock sources available today. The second section defines and distinguishes between various parameters used to describe clocks. This section also provides methods of measuring some of these parameters.

    This the third edition of the Writing Device Drivers articles. The first article helped to simply get you acquainted with device drivers and a simple framework for developing a device driver for NT. The second tutorial attempted to show to use IOCTLs and display what the memory layout of Windows NT is. In this edition, we will go into the idea of contexts and pools. The driver we write today will also be a little more interesting as it will allow two user mode applications to communicate with each other in a simple manner. We will call this the “poor man’s pipes” implementation.

    From helping to assess the value of new medical treatments to evaluating the factors that affect our opinions and behaviors, analysts today are finding myriad uses for categorical data methods. In this book we introduce these methods and the theory behind them. Statistical methods for categorical responses were late in gaining the level of sophistication achieved early in the twentieth century by methods for continuous responses. Despite influential work around 1900 by the British statistician Karl Pearson, relatively little development of models for categorical responses occurred until the 1960s. In this book we describe the early fundamental work that still has importance today but place primary emphasis on more recent modeling approaches. Before outlining

    北京大学ACM比赛题目 In 1742, Christian Goldbach, a German amateur mathematician, sent a letter to Leonhard Euler in which he made the following conjecture: Every even number greater than 4 can be written as the sum of two odd prime numbers. For example: 8 = 3 + 5. Both 3 and 5 are odd prime numbers. 20 = 3 + 17 = 7 + 13. 42 = 5 + 37 = 11 + 31 = 13 + 29 = 19 + 23. today it is still unproven whether the conjecture is right. (Oh wait, I have the proof of course, but it is too long to write it on the margin of this page.) Anyway, your task is now to verify Goldbach s conjecture for all even numbers less than a million.

    Welcome to Beginning Algorithms, a step-by-step introduction to computing algorithms for the real world. Developers use algorithms and data structures every day of their working lives. Having a good understanding of these algorithms and knowledge of when to apply them is essential to producing software that not only works correctly, but also performs efficiently. This book aims to explain those algorithms and data structures most commonly encountered in day-today software development, while remaining at all times practical, concise, and to the point, with little or no verbiage to distract from the core concepts and examples.

  • 用fpga实现的DA转换器

    用fpga实现的DA转换器,有说明和源码,VDHL文件。 A PLD Based Delta-Sigma DAC Delta-Sigma modulation is the simple, yet powerful, technique responsible for the extraordinary performance and low cost of today s audio CD players. The simplest Delta-Sigma DAC consists of a Delta-Sigma modulator and a one bit DAC. Since, both of these components can be realized using digital circuits, it is possible to implement a low precision Delta-Sigma DAC using a PLD.

    Pegasus is an open-source implementationof the DMTF CIM and WBEM standards. It is designed to be portable and highly modular. It is coded in C++ so that it effectively translates the object concepts of the CIM objects into a programming model but still retains the speed and efficiency of a compiled language. Pegasus is designed to be inherently portable and builds and runs today on most versionsof UNIX(R), Linux, OpenVMS, and Microsoft Windows.
