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.

GPS 接收程序 DEMO。 HsGpsDll Library 1.1 A GPS Control/Component for C/C++ HsGpsDll is a Windows Dynamic Link Library which provides access to any NMEA-183 compliant GPS receiver via a serial communications port. HsGpsDll is designed for use from Visual C, Visual Basic or other languages, capable of calling DLL functions. HsGpsDll allows a user application to read from a GPS device the current GPS position fix, velocity over ground (speed in kilometers per hour), plus number of of sattelites in view, current altitude (against mean sea level) and UTC date and time

Introduction Computer security is undeniably important, and as new vulnerabilities are discovered and exploited, the perceived need for new security solutions grows. "Trusted computing" initiatives propose to solve some of today s security problems through hardware changes to the personal computer. Changing hardware design isn t inherently suspicious, but the leading trusted computing proposals have a high cost: they provide security to users while giving third parties the power to enforce policies on users computers against the users wishes -- they let others pressure you to hand some control over your PC to someone else. This is a "feature" ready-made for abuse by software authors who want to anticompetitively choke off rival software. It needn t be this way: a straightforward change to the plans of trusted computing vendors could leave the security benefits intact while ensuring that a PC owner s

The combinatorial core of the OVSF code assignment problem that arises in UMTS is to assign some nodes of a complete binary tree of height h (the code tree) to n simultaneous connections, such that no two assigned nodes (codes) are on the same root-to-leaf path. Each connection requires a code on a specified level. The code can change over time as long as it is still on the same level. We consider the one-step code assignment problem: Given an assignment, move the minimum number of codes to serve a new request. Minn and Siu proposed the so-called DCAalgorithm to solve the problem optimally. We show that DCA does not always return an optimal solution, and that the problem is NP-hard. We give an exact nO(h)-time algorithm, and a polynomial time greedy algorithm that achieves approximation ratio Θ(h). Finally, we consider the online code assignment problem for which we derive several results

MPI stands for the Message Passing Interface. Written by the MPI Forum (a large committee comprising of a cross-section between industry and research representatives), MPI is a standardized API typically used for parallel and/or distributed computing. The MPI standard is comprised of 2 documents: MPI-1 (published in 1994) and MPI-2 (published in 1996). MPI-2 is, for the most part, additions and extensions to the original MPI-1 specification. The MPI-1 and MPI-2 documents can be downloaded from the official MPI Forum web site: http://www.mpi-forum.org/. Open MPI is an open source, freely available implementation of both the MPI-1 and MPI-2 documents. The Open MPI software achieves high performance the Open MPI project is quite receptive to community input.

VHDL是由美国国防部为描述电子电路所开发的一种语言，其全称为(Very High Speed Integrated Circuit) Hardware Description Language。 与另外一门硬件描述语言Verilog HDL相比，VHDL更善于描述高层的一些设计，包括系统级（算法、数据通路、控制）和行为级（寄存器传输级），而且VHDL具有设计重用、大型设计能力、可读性强、易于编译等优点逐渐受到硬件设计者的青睐。但是，VHDL是一门语法相当严格的语言，易学性差，特别是对于刚开始接触VHDL的设计者而言，经常会因某些小细节处理不当导致综合无法通过。为此本文就其中一些比较典型的问题展开探讨，希望对初学者有所帮助，提高学习进度。
