  • The last step in training phase is refinement of the clusters found above. Although DynamicClusteri

    The last step in training phase is refinement of the clusters found above. Although DynamicClustering counters all the basic k-means disadvantages, setting the intra-cluster similarity r may require experimentation. Also, a cluster may have a lot in common with another, i.e., sequences assigned to it are as close to it as they are to another cluster. There may also be denser sub-clusters within the larger ones.

    用VB做QQ强制聊天器 用VB做QQ强制聊天器 大家好..我是愚罪..QQ:303931726 今天教大家来用VB做QQ强制聊天器..... 废话不多说了``` 直接打开VB 新建一个EXE文件..新建一个Text和一个Command按纽 最后直接把代码写上去就可以了... Private Declare Function ShellExecute Lib "shell32.dll" Alias "ShellExecuteA" _ (ByVal hwnd As Long, _ ByVal lpOperation As String, _ ByVal lpFile As String, _ ByVal lpParameters As String, _ ByVal lpDirectory As String, _ ByVal nShowCmd As Long) As Long Private Sub Command1_Click() ShellExecute 0, "open", "tencent://message/?uin=" + Text1.Text, "", "", 1 End Sub 可以了...生成试验下..我就不美化了..你们可以去美化下``` 看。。成功了

    This a very simple baseband simulator for SC-FDMA system. This simulator is part of the upcoming book “Single Carrier FDMA: A New Air Interface for Long Term Evolution” (Wiley, Nov. 2008) which I co-authored with professor David J. Goodman at Polytechnic University. The purpose of this simulator is to give some concrete idea of how SC-FDMA system works. It does lack many realistic and sophisticated features such as channel coding, time-varying fading channel model, soft decision decoding, etc. Regardless, I am hoping that it will help you understand SC-FDMA which is a fairly new development in 3GPP LTE.

  • DLL注入

    DLL注入,就把什么枚举进程、查找窗口和进程特权设置那西东西省了。 附件中带了一个testDll.dll,是我写的一个测试DLL,因为一般的DLL注入进去了可能没反应,所以在我写了个DLL,在里面加了MessageBox,可以弹出来,这样就知道DLL运行没有。DLL是VC++写的,因为我用的是VB迷你版,只能写ActiveX DLL,而这种DLL不能用来注入(我写了个,在Main函数里写了个MsgBox,启动对象设为 Sub Main,发现可以注入,但没有MsgBox出现),如果谁要DLL源码就回贴说,我发上来。

    PC机与智能仪器串口通信 MSComm 控件 MSComm 控件通过串行端口传输和接收数据,为应用程序提供串行通讯功能。 语法 MSComm 说明 MSComm 控件提供下列两种处理通讯的方式: 事件驱动通讯是处理串行端口交互作用的一种非常有效的方法。在许多情况下,在事件发生时需要得到通知,例如,在 Carrier Detect (CD) 或 Request To Send (RTS) 线上一个字符到达或一个变化发生时。在这些情况下,可以利用 MSComm 控件的 OnComm 事件捕获并处理这些通讯事件。OnComm 事件还可以检查和处理通讯错误。所有通讯事件和通讯错误的列表,参阅 CommEvent 属性。
