INDUCTION MOTOR RUN (Currents and speed as state variables) The motor is running at a specified load. After reaching steady state in an initialization first run, the initial conditions are established for a second run in which the load is pulsating. The dynamic equations are expressed in canonical first-order matrix form adopting currents and speed as state variables, and are solved using ODE45. The user has the choice of selecting one of three common (dq) reference frames: STATOR, ROTOR or SYNCHRONOUS. The torque, speed,and current responses are plotted. -INDUCTION MOTOR RUN (Currents and speed as state variables) The motor is running at a specified load.

微软的SQL SERVER数据库的Image、text等字段都属于二进制的大对象。这些对象的存取和其他轻型对象略有不同。 　　微软.NET Framework的System.IO命名空间下给我们提供了一个FileStream文件流类。我们可以使用这个文件流对二进制大对象轻松进行读写。 　　我实现了一个简单的WinForm程序，这个程序通过点击“Open”按钮选择一个bmp或者jpg文件，并显示在图形控件PictureBox中。通过“Save”按钮存入数据库。点击“View”CheckBox可以切换到浏览状态，观看存入数据库的图片。 　　由于对二进制大对象使用的流操作，所以对于任何文件都具有通用性。读写文本文件也可以这么做。 -Microsoft s field and so on SQL SERVER database Image, text all belongs to binary the big object. These objects deposits and withdrawals and other light objects have the difference slightly. MicrosoftNET Framework System.Under the IO naming space provided a FileStream document to us to flow the kind. We may use this document to flow to the binary big object with ease carry on read-write. I have realized a simple WinForm procedure, this procedure through clicks on "Open" the button to choose bmp or the jpg document, and the demonstration controls in PictureBox in the graph. The button stores the database through "Save". Clicks on "View" CheckBox to b

ASP.NET与数据库编程 1.在本实例中，使用的是SQL Server 2000的数据库而这里只给了对应的Access数据库，如果你想在你的机器上在运行程序需要在SQL Server下重新建立一样的数据库，或者使用前面介绍的导入导出工具将.mdb数据库转化为SQLServer数据库。 确保你的机器上的服务名，和程序中的代码要统一。 2.将library文件夹复制到C:Inetpubwwwroot目录下(一般情况是这样），即可运行程序 3.运行ASP.NET程序先要保证您的机器上正确的建立了一个站点，然后将这里的程序考入站点目录下即可。首页为WebForm1.aspx -ASP.NET programming with a database. In this example, the use of the SQL Server 2000 database here only to the corresponding Access database, if you want your machines running the program in SQL Server under the re-establishment of the same database, or use the above-described I. income derived tools. mdb database into a SQL Server database. Make sure your machine from the services, and procedures necessary to unify the code. 2. Library folder will be copied to C : Inetpub wwwroot directory (this is the general), can run programs 3.
