竞争性自适应重加权算法（CARS）是通过自适应重加权采样（ARS）技术选择出PLS模型中回归系数绝对值大的波长点，去掉权重小的波长点，利用交互验证选出RMSECV指最低的子集，可有效寻出最优变量组合。(Competitive adaptive reweighted algorithm (CARS) is obtained by adaptive reweighted sampling (ARS) technique is selected in the PLS model regression coefficients with large absolute values of wavelength, remove the weight of small wavelength, using cross validation to select the RMSECV refers to the minimum subset, can effectively find out the optimal combination of variables.)

This Unix C code monitors a web server every few minutes by trying to retrieve its home page. It sends you email when it can t connect, and every so often while the server is still down. It sends a final message when it comes back up. If you have email paging, just direct the email to your pager address.-This Unix C code monitors a web server every few minutes by trying to retrieve its home page.

旋转的地球flash特效，3维旋转的地球仪源码素材，3D地球Flash源文件，其实是用了两个层，不同的透明度和色度，向相反的方向运动，再用一个圆形遮罩，便可实现3D地球，当然了，这是比较简单的实现方法。
