Verilog HDL: Magnitude For a vector (a,b), the magnitude representation is the following: A common approach to implementing these arithmetic functions is to use the Coordinate Rotation Digital Computer (CORDIC) algorithm. The CORDIC algorithm calculates the trigonometric functions of sine, cosine, magnitude, and phase using an iterative process. It is made up of a series of micro-rotations of the vector by a set of predetermined constants, which are powers of two. Using binary arithmetic, this algorithm essentially replaces multipliers with shift and add operations. In a Stratix™ device, it is possible to calculate some of these arithmetic functions directly, without having to implement the CORDIC algorithm.

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。

Purpose of this White Paper This white paper describes a collection of standards, conventions, and guidelines for writing solid Java code. They are based on sound, proven software engineering principles that lead to code that is easy to understand, to maintain, and to enhance. Furthermore, by following these coding standards your productivity as a Java developer should increase remarkably – Experience shows that by taking the time to write high-quality code right from the start you will have a much easier time modifying it during the development process. Finally, following a common set of coding standards leads to greater consistency, making teams of developers significantly more productive.

Ajax, the popular term for Asynchronous JavaScript and XML, is one of the most important combinations of technologies for web developers to know these days. With its rich grouping of technologies, Ajax developers can create interactive web applications with XML-based web services, using JavaScript in the browser to process the web server response.

The source code for this package is located in src/gov/nist/sip/proxy. The proxy is a pure JAIN-SIP application: it does not need proprietary nist-sip classes in addition of those defined in JAIN-SIP 1.1, you can substitute the NIST-SIP stack by another JAIN-SIP-1.1 compliant stack and it should interoperate. he proxy can act as presence server and be able to process NOTIFY and SUBSCRIBE requests. If this parameter is disabled, the proxy will simply forward those kind of requests following the appropriate routing decision.

This directory builds the Tape class driver for Microsoft® Windows® Server 2003. The class driver implements device-independent support, and exports support routines for device-specific tape miniclass drivers. It handles device-independent tape requests and calls the tape minidriver routines to process device-specific functions. Class driver splits transfer requests, when necessary, to fit the maximum transfer size for the underlying host bus adapter. It also provides device-independent, tape-specific error handling, and calls the tape miniclass driver s device-specific error handling routines.

An unsatisfactory property of particle filters is that they may become inefficient when the observation noise is low. In this paper we consider a simple-to-implement particle filter, called ‘LIS-based particle filter’, whose aim is to overcome the above mentioned weakness. LIS-based particle filters sample the particles in a two-stage process that uses information of the most recent observation, too. Experiments with the standard bearings-only tracking problem indicate that the proposed new particle filter method is indeed a viable alternative to other methods.
