用摄像头来测距的电子教程以及源码

分享一个外国人编写的FDTD程序,可以用来计算微带线和微带贴片天线,程序中采用的是均匀网格划分,但也可以在容易地在它基础上改写成非均匀网格.其边界条件与Sheen的程序不同,这里采用二阶技术.(Prepared to share a foreigner FDTD procedures, can be used to calculate the microstrip lines and microstrip patch antenna, the procedure used is uniform mesh, but can also easily rewrite it into the basis of non-uniform grid. its boundary conditions with different processes and Sheen, where second-order technology.)

相信大家都已经见过了，就是一个载入动画，环形的圆环在不停的旋转，支持FireFox、IE7、Mac等多种风格，还可以背景透明，这是C#专用控件。(I believe we all have seen, is a load animation, the annular ring spinning, support FireFox, IE7, Mac and a variety of styles, but also a transparent background, which is the exclusive control of the C#.)

根据队列搜索算法的基本思想，现设计了一个简单的结构体数组如下定义代码所示。此结构体数组具备控制结点搜索和存储结点信息和路径的功能，可以较好的实现TDN的最小时间路径搜索。(Search algorithm based on the basic idea of ​ ​ the queue is now designed a simple structure array as defined code. This structure array with the control node and storage node information search and path functions, you can achieve better TDN minimum time path search.)
