H.264/AVC, the result of the collaboration between the ISO/IEC Moving Picture Experts Group and the ITU-T Video Coding Experts Group, is the latest standard for video coding. The goals of this standardization effort were enhanced compression efficiency, network friendly video representation for interactive (video telephony) and non-interactive applications (broadcast, streaming, storage, video on demand). H.264/AVC provides gains in compression efficiency of up to 50％ over a wide range of bit rates and video resolutions compared to previous standards. Compared to previous standards, the decoder complexity is about four times that of MPEG-2 and two times that of MPEG-4 Visual Simple Profile. This paper provides an overview of the new tools, features and complexity of H.264/AVC.

neural network utility is a Neural Networks library for the C++ Programmer. It is entirely object oriented and focuses on reducing tedious and confusing problems of programming neural networks. By this I mean that network layers are easily defined. An entire multi-layer network can be created in a few lines, and trained with two functions. Layers can be connected to one another easily and painlessly.

数据加密算法（Data Encryption Algorithm，DEA）的数据加密标准（Data Encryption Standard，DES）是规范的描述，它出自 IBM 的研究工作，并在 1997 年被美国政府正式采纳。它很可能是使用最广泛的秘钥系统，特别是在保护金融数据的安全中，最初开发的 DES 是嵌入硬 件中的。通常，自动取款机（Automated Teller Machine，ATM）都使用 DES。文件是DES代码的VHDL描述

The SL74HC573 is identical in pinout to the LS/ALS573. The device inputs are compatible with standard CMOS outputs with pullup resistors, they are compatible with LS/ALSTTL outputs. These latches appear transparent to data (i.e., the outputs change asynchronously) when Latch Enable is high. When Latch Enable goes low, data meeting the setup and hold time becomes latched.

The purpose of this document is to define the format of the messages and data being communicated between microprocessors used in heavy-duty vehicle applications. It is meant to serve as a guide toward a standard practice to promote software compatibility among microcomputer based modules. This document is to be used with SAE J1708. SAE J1708 defines the requirements for the hardware and basic protocol that is needed to implement this document.

Fully revised to cover the latest standards and technologies, XML and Java(TM), Second Edition provides the practical solutions developers need to design powerful and portable Web-based applications. Featuring step-by-step examples, this book focuses on harnessing the power of Java(TM) and XML together to streamline the development process. XML and Java(TM), Second Edition provides new coverage of emerging areas such as document management, databases, messaging, servlets, JDBC, data binding, security, and more. It begins with an overview of XML programming techniques, standard APIs, and tools. Building upon this foundation, the book goes on to cover the latest technologies, including DOM Level 2, SAX2, XSLT, SOAP, WSDL, and UDDI. It explores the role of these major middleware technologies in XML and Java-based Web application development, as well as the limitations and potential pitfalls.

KML is an XML grammar used to encode and transport representations of geographic data for display in an earth browser. Put simply: KML encodes what to show in an earth browser, and how to show it. KML uses a tag-based structure with nested elements and attributes and is based on the XML standard.

1. 异常和标准C 对它的支持 （前言略） 1.1 异常分类 基于Dr. GUI 的建议，我把我的第一个专栏投入到“程序异常”的系列上。我认识到， “exception”这个术语有些不明确并和上下文相关，尤其是C++标准异常（C++ standard exceptions）和Microsoft 的结构化异常（structured exception handling）。不幸的的是， “异常”一词太常见了，随时出现在语言的标准和常见的编程文献中。因为不想创造一个新 名词，所以我将尽力在此系列的各部分中明确我对“异常”的用法。 Part 1 概述通常意义上的异常的性质，和标准C 库提供的处理它们的方法。 Part 2 纵览Microsoft 对这些标准C 库方法的扩展：专门的宏和结构化异常处理。 Part 3 及其余将致力于标准C++异常处理体系。 （C 语言使用者可能在Part2 后放弃，但我鼓励你坚持到底；我所提出的许多点子同样 适用于C，虽然不是很直接。）
