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。

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.
