企業內部的很多業務都可以抽象為一個或者若干個工作流，最典型的是收發文工作流。一個發文流程可能要經歷起草，審批，校對，領導簽字，傳閱等步驟。傳統的辦公模式完成此流程需要投入很多人力，而且運轉起來較慢，容易出錯，如果采用辦公自動化系統，公文的流轉就可以自動化，顯然有很多好處。 UML（Unified Modeling Language)是一種面向對象的建模語言，它已經廣泛用于面向對象系統的分析和設計。統一過程(Unified Process)是一種軟件工程方法，它將軟件開發過程分為一系列的工作流程(Workflow)，充分發揮了迭代的開發思想，是軟件開發成功的重要因素。 Struts是基于JAVA的一個開源項目，采用模塊化的設計思想將業務邏輯，數據存儲和用戶界面分離，簡化了企業級應用程序的構建。 本文描述了葫蘆島鋅廠的辦公自動化系統的開發過程，依據統一過程的開發思想，利用UML構建和描述系統的結構與行為，并用Struts完成了系統的最終實現。

本書由知名的C++專家Matthew H．Austern執筆，引導你進入泛型編程思維模型，并將你帶往此一模型的最重要成品：C++ Standard Template Library(STL)。本書揭示STL的奧秘，告訴你STL不僅僅是一組方便運用的容器類(container classes)。對于泛型組件和可交互作用的組件而言，STL是一個具備擴充能力的框架(framework)、 《泛型編程與STL》闡述了泛型編程的中心思想：concepts、Modeling、refinement，并為你展示這些思想如何導出STL的基礎概念：iterators、containers、function objects。循此路線，你可以把STL想像為一個由concepts(而非明確之functions或classes)組成的程序庫：、你將學習其正式結構并因此獲得其潛在威力所帶來的完整優勢。本書使你能夠： ●以你自己的“可移植組件”及“可交互作用之泛型組件”擴充STL； ●產生一些算法，讓它們和它們所處理之型別(types)及數據結構徹底劃清界線； ●撰寫更精致、更高效、更有效力的代碼，可跨平臺重復使用。

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
