pca
这篇文章是盲信号处理，因为是英文文章，所以大家看内容就好了。(Principal component analysis (PCA) is a mainstay of modern data analysis- a black box that
is widely used but poorly understood. The goal of this paper is to dispel the magic behind this
black box. This tutorial focuses on building a solid intuition for how and why principal component
analysis works furthermore, it crystallizes this knowledge by deriving from simple intuitions, the
mathematics behind PCA . This tutorial does not shy away from explaining the ideas informally,
nor does it shy away from the mathematics. The hope is that by addressing both aspects, readers
of all levels will be able to gain a better understanding of PCA as well as the when, the how and
the why of applying this technique.)

MeshfreeVIE
该论文介绍了电磁场积分方程的无网格数值计算方法，传统的体积分数值计算都需要进行网格剖分，网格剖分的好坏直接影响着数值计算的速度和精度，很多精细结构很难用网格来模拟，无网格技术可以很好地解决此类问题！(This paper describes the meshless numerical method electromagnetic integral equations, numerical integration of traditional body calculations require meshing, meshing a direct impact on the speed and accuracy of numerical calculation, many very fine structure difficult to simulate with the grid, no grid can solve this problem!)

counting-sheep
前一段时间我有睡眠问题。我曾经躺在床上，盯着天花板，几个小时。后来有一天，我的外婆建议我试着数羊后，我已经上床睡觉。与往常一样，当我的奶奶暗示的东西，我决定尝试一下。唯一的问题是，有没有羊的时候，我就去睡觉各地进行计数。
创意，因为我，这是不会阻止我。我坐下来写，使得字符，其中＃代表羊的网格，而计算机程序。草（或任何你喜欢的，只是没有羊）。为了使计算更有趣，我也决定要数绵羊，而不是单一的成群的牛羊。两只羊在同一个群，如果他们都有一个共同的一面（上，下，左或右）。另外，如果羊A是在同一羊群如羊B和羊B处于同一羊群如羊℃，然后羊A和C是在同一个群。
现在，我已经有了一个新的问题。虽然这些计数羊居然帮我睡着了，我觉得这是非常无聊的。为了解决这个问题，我决定我需要做的计数为我另一台计算机上的程序。然后，我就可以只启动这两个程序之前，我去睡觉，我会睡个好觉，直到没有任何干扰的早晨。我需要你给我写的这个程序。(A while ago I had trouble sleeping. I used to lie awake, staring at the ceiling, for hours and hours. Then one day my grandmother suggested I tried counting sheep after I d gone to bed. As always when my grandmother suggests things, I decided to try it out. The only problem was, there were no sheep around to be counted when I went to bed.
Creative as I am, that wasn t going to stop me. I sat down and wrote a computer program that made a grid of characters, where# represents a sheep, while . is grass (or whatever you like, just not sheep). To make the counting a little more interesting, I also decided I wanted to count flocks of sheep instead of single sheep. Two sheep are in the same flock if they share a common side (up, down, right or left). Also, if sheep A is in the same flock as sheep B, and sheep B is in the same flock as sheep C, then sheeps A and C are in the same flock.
Now, I ve got a new problem. Though counting these sheep actually helps me fall asleep, I find)
