企业内部的很多业务都可以抽象为一个或者若干个工作流，最典型的是收发文工作流。一个发文流程可能要经历起草，审批，校对，领导签字，传阅等步骤。传统的办公模式完成此流程需要投入很多人力，而且运转起来较慢，容易出错，如果采用办公自动化系统，公文的流转就可以自动化，显然有很多好处。 UML（Unified modeling Language)是一种面向对象的建模语言，它已经广泛用于面向对象系统的分析和设计。统一过程(Unified Process)是一种软件工程方法，它将软件开发过程分为一系列的工作流程(Workflow)，充分发挥了迭代的开发思想，是软件开发成功的重要因素。 Struts是基于JAVA的一个开源项目，采用模块化的设计思想将业务逻辑，数据存储和用户界面分离，简化了企业级应用程序的构建。 本文描述了葫芦岛锌厂的办公自动化系统的开发过程，依据统一过程的开发思想，利用UML构建和描述系统的结构与行为，并用Struts完成了系统的最终实现。

本书由知名的C++专家Matthew H．Austern执笔，引导你进入泛型编程思维模型，并将你带往此一模型的最重要成品：C++ Standard Template Library(STL)。本书揭示STL的奥秘，告诉你STL不仅仅是一组方便运用的容器类(container classes)。对于泛型组件和可交互作用的组件而言，STL是一个具备扩充能力的框架(framework)、 《泛型编程与STL》阐述了泛型编程的中心思想：concepts、modeling、refinement，并为你展示这些思想如何导出STL的基础概念：iterators、containers、function objects。循此路线，你可以把STL想像为一个由concepts(而非明确之functions或classes)组成的程序库：、你将学习其正式结构并因此获得其潜在威力所带来的完整优势。本书使你能够： ●以你自己的“可移植组件”及“可交互作用之泛型组件”扩充STL； ●产生一些算法，让它们和它们所处理之型别(types)及数据结构彻底划清界线； ●撰写更精致、更高效、更有效力的代码，可跨平台重复使用。

This the implementation of structural SVM for training complex alignment models for protein sequence alignment, especially for homology modeling. The structural SVM algorithm can incorporate many relevant features like secondary structure, relative exposed surface area, profiles and their various interaction into the alignment model. It was developed under Linux and compiles under gcc, built upon the svm^light software by Thorsten Joachims.

This submission includes the presentation and model files that were used in delivering a webinar on 12-15-05 that covered the topic of modeling Hybrid Electric Vehicles. Hybrid electric vehicles (HEVs) have proven they can substantially improve fuel economy and reduce emissions. Because HEVs combine an electric drive with the internal combustion engine (ICE) in the powertrain, the vehicle?s kinetic energy can be captured during braking and transformed into electrical energy in the battery. The dual power source also means that the ICE can be reduced in size and can operate at its most efficient speeds.

Carrier-phase synchronization can be approached in a general manner by estimating the multiplicative distortion (MD) to which a baseband received signal in an RF or coherent optical transmission system is subjected. This paper presents a unified modeling and estimation of the MD in finite-alphabet digital communication systems. A simple form of MD is the camer phase exp GO) which has to be estimated and compensated for in a coherent receiver. A more general case with fading must, however, allow for amplitude as well as phase variations of the MD. We assume a state-variable model for the MD and generally obtain a nonlinear estimation problem with additional randomly-varying system parameters such as received signal power, frequency offset, and Doppler spread. An extended Kalman filter is then applied as a near-optimal solution to the adaptive MD and channel parameter estimation problem. Examples are given to show the use and some advantages of this scheme.

Data mining (DM) is the extraction of hidden predictive information from large databases (DBs). With the automatic discovery of knowledge implicit within DBs, DM uses sophisticated statistical analysis and modeling techniques to uncover patterns and relationships hidden in organizational DBs. Over the last 40 years, the tools and techniques to process structured information have continued to evolve from DBs to data warehousing (DW) to DM. DW applications have become business-critical. DM can extract even more value out of these huge repositories of information.

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
