歡迎使用ERwin信息模型，以前如果你從未見過模型，ERwin Methods Guide將幫助你了解什么是模型，以及它適合于什么。如果你已經一些有使用數據和信息模型的經驗，那么你知道它在業務需求中是很有用的。如果在設計新的信息系統或在維護和修改存在的東西，模型能幫助你。本文沒有包括信息模型的許多細節。但是，到你讀完它的時候，你將足夠地了解它，即使你僅僅初學者，ERwin的方法也將為你工作。本文覆蓋了由 ERwin支持的信息模型方法，它不包括了ERwin的詳細使用，如何使用 ERwin工具請見”ERwin User s Guide”。由 ERwin支持的信息模型方法是神秘的縮寫字：”IDEF1X”，IDEF1X方法由 U.S.空軍開發。目前，它應用于空軍、政府機構、航空工業和財政部門、大公司、大型企業。并且，信息模型在各種主要的管理嚴格的大公司是必需的。

小蟲新聞管理系統 V1.0(jsp+javabean+mysql) 1.解壓縮 (如解壓縮到D:\tomcat4\webapps\ROOT\news目錄下) 2.進入classes目錄，打開news.txt。 修改mysql.url(數據庫聯接地址及數據庫名),mysql.user(用戶名)，mysql.password(密碼)，ilog(數據庫聯接池日志文件，請注意路徑分隔符為“\\”，在linux中是“/”)； 3.建數據庫，并將database目錄下news.sql導入；news.sql中37行中用戶可修改你想要的密碼，但用戶名admin不能更改，否則不能實現超級管理員的功能 4.運行管理文件 --> admin/index.jsp 對系統進行一些基本設置(首先添加欄目) (如: http://localhost:8080/news/admin/index.jsp ) 5.OK!歡迎使用 (如：http://localhost:8080/news/index.jsp )

A MATLAB GUI platform for realizing the radiation pattern of narrowband beamformer with random array geometry. User can specify the array geometry, directions of incoming signals, noise power, and the type of beamformer. Useful for gaining insight about collaborative beamforming in sensor networks and random arrays. You need both randomarray.fig and randomarray.m to work.

Description: Microsoft?Windows?HTTP Services (WinHTTP) provides developers with a server-supported, high-level interface to the HTTP/1.1 Internet protocol. WinHTTP is designed to be used primarily in server-based scenarios by server applications that communicate with HTTP servers. WinHTTP is also designed for use in system services and HTTP-based client applications. WinHTTP is more secure and robust than WinInet. However, single-user applications that need FTP or gopher functionality, cookie persistence, caching, automatic credential dialog handling, Internet Explorer compatibility, or downlevel platform support should still consider using WinInet.

It can be argued that the current free-software movement is the most important thing happening in computing today. We are in the midst of a major shift from all software being proprietary and closely held by individual companies to a large body of software that can be freely acquired and used by anyone for any purpose. Free software now includes not only programming language compilers and linkers, but numerous utilities, graphical user interface environments, and even entire operating systems.

This file contains board-specific information for the Motorola cpv3060 target board. Specifically, this file contains information on any BSP interface changes from previous software or hardware versions, and contains caveats that the user must be aware of before using this BSP. Additionally, the target board s reference entry (i.e., cpv3060/target.nr) provides board-specific information necessary to run VxWorks, and should be read before this BSP is used.

This file contains board-specific information for the Motorola LoPEC in support of the lopec BSP. Specifically, this file contains information on any BSP interface changes from previous software or hardware versions, and contains caveats that the user must be aware of before using this BSP. Additionally, the target board s manual page entry (for example, lopec/target.nr) provides board-specific information necessary to run VxWorks, and should be read before this BSP is used.

Excel的強大函數功能，為我們帶來了極大方便，雖然它有200多個函數，但有時我們為實現一項規定的功能，可能用到幾個函數或者采用嵌套函數，這樣應用起來，也不太方便。其實對于我們經常用到的功能，我們可以創建自定義函數UDF(User—defined function)，它的運行與Excel中自帶的函數完全相同。建立自定義函數有以下幾個優點：建立自己特殊的功能和名稱的函數；能將復雜的、嵌套的、多個原有的函數組合在一起，發揮更大的威力。

SuperLU is a general purpose library for the direct solution of large, sparse, nonsymmetric systems of linear equations on high performance machines. The library is written in C and is callable from either C or Fortran. The library routines will perform an LU decomposition with partial pivoting and triangular system solves through forward and back substitution. The LU factorization routines can handle non-square matrices but the triangular solves are performed only for square matrices. The matrix columns may be preordered (before factorization) either through library or user supplied routines. This preordering for sparsity is completely separate from the factorization. Working precision iterative refinement subroutines are provided for improved backward stability. Routines are also provided to equilibrate the system, estimate the condition number, calculate the relative backward error, and estimate error bounds for the refined solutions.
