surf特征识别与多图像特征匹配与误匹配矫正

ecos驱动文档，不错的操作系统eCos_drv.rar-eCos driver files, a good operating system eCos_drv.rar

在C++中，可以直接用[][]实现二维数组，但是[][]不能重载，所以，用模版与指针实现的自定义二维数组-2d array implemented using pointer or template

VC++ 模拟实现网络语音电话，类似语音聊天的功能，这是一个通过网络实现的网络语音电话，功能目前是比较基础的，仅供学习参考吧。本实例当时在Windows 2000环境下运行通过。相关的代码如下： 　　#define BUFFERSIZE 5120 //缓冲区大小 　　static HWAVEIN hWaveIn ; //录音设备句柄 　　static HWAVEOUT hWaveOut ; //播放设备句柄 　　static PBYTE pBufferIn[2]; //用于接收和播放的两块缓冲区 　　static PBYTE pBufferOut[2]; //用于发送和录音的两块缓冲区 　　static PWAVEHDR pWHIn[2]; //用于录音的PWAVEHDR结构数组 　　static PWAVEHDR pWHOut[2]; //用于播放的PWAVEHDR结构数组 　　static WAVEFORMATEX waveform ; //用于打开音频设备的WAVEFORMATEX结构 　　int nIn = 0; //当前播放缓冲区号 　　int nOut = 0; //当前录音缓冲区号 　　int nComState = 1; //显示通话状态信息的变量 　　CString LocalIP; //本机IP地址 　　CString RemoteIP; //远端主机IP地址 　　CServerAS sServer; //服务器套接字 　　CClientAS sClient; //客户端套接字 　　CServerAS sListen; //监听套接字 　　BOOL ConnectDown = FALSE; //“连接”按钮是否被按下 　　BOOL sState = FALSE; //是否处于服务器端状态 　　BOOL cState = FALSE; //是否处于客户端状态

医院门诊管理系统，根据管理员的登录，可以进行医院门诊的管理，对病人进行住院和医用的记录-Hospital out-patient management system, according to the registry administrator, you can out-patient hospital management, hospital patients and medical records

游戏地图编辑器及源代码，有什麽功能自己看看吧-game map editor and source code, a function of their own to see what it

NSEG是美国兰利研究中心推出的飞行器起飞、爬升、巡航、加速、下降、减速和着陆等各个过程分析软件。(NSEG was developed to perform rapid aircraft mission analyses. It is based upon the use of approximate equations of motion whose form varies with the type of flight segment. Flight segments considered are takeoff, accelerations, climbs, cruises, descents, decelerations, and landings. Layered atmosphere options are available. The program can also be used for flight envelope mapping. NSEG provides the capability to analyze aircraft missions from low to hypersonic speeds. Realistic and detailed vehicle characteristics are input to NSEG to permit accurate mission analysis. NSEG allows engine scaling so as to fit the design under analysis. NSEG contains several approximate flight path optimization capabilities based on Rutowski energy-like criteria for considering minimum time or fuel flight segments and maximum range segments during climb or descent. Takeoff and landing analysis is based on the Air Force Flight Dynamics Laboratory DATCOM method of high lift aerodynamic modelling)

主要是针对codesys入门手册，对新手能起非常大的帮助。希望对大家能起作用(Mainly for codesys introduction manual, can be very helpful to novice.Hopefully that worked for you)

说明：  

Newmark-β法，几种程序，以求解振动微分方程(Solving oscillatory differential equations)

说明：  柔性直流输电技术是比传统直流输电更先进的直流输电技术。所以除了拥有传统高压直流输电技术即可以控制有功功率又可以控制无功功率、输电距离基本不受限制、直流输电比交流输电更稳定、实现异步系统互联和减轻环境影响的优点，柔性直流输电还具备许多自身特有的优点。(Flexible HVDC transmission technology is more advanced than traditional HVDC transmission technology. Therefore, in addition to the advantages of traditional HVDC technology, such as active power control and reactive power control, almost unlimited transmission distance, more stable HVDC than ac transmission, asynchronous system interconnection and environmental impact reduction, flexible HVDC also has many unique advantages.)
