It did CMA using 6 other homes, attached some pictures of the house exterior
and interior, and provided info on the square footage, etc. I think those
paramaters (including the purchase price) are all given by the listing
broker. |

发帖数: 46 | 3 I met a wired problem when I use apache web server to run perl scripts. When I
changed my code, it seemed the web server could not reflect the modification
timely. Even I delete the code, the web server still can display some old
pages. If I refresh it, it will display some history page. But it can not
reflect my current version. After a period of time, eg. the next day, it may
can display. I was wondering if it is because the web server has cached my
page. Is there a paramater that lets the web |

发帖数: 67 | 4 Thank you for the reply. The report was designed by someone else, and I just
use it. Then I found out those two paramaters were in the report. Since they
are useless, I just deleted them and now the report works well.
Thank you again. |

发帖数: 3584 | 5 没有在WIN7上试过，VISTA上也是装完了系统才建的RAID，系统不认，
但我不是建的系统盘，也是折腾了一翻，把当时的笔记贴上来吧，
BIOS里设了RAID，系统不认呀，而且直接蓝屏。
是这个贴子告诉我怎么能让机器在RAID设了之后还能进VISTA，原链接找不到了，重要
的是不明白这个设置是什么意思，因此一定要记下来。而且接下来的事儿与这个哥们儿
说得很象
I noticed that the driver was named iaStorV.sys, so I did a search for it
and found it already installed in theWindows\System32\Drivers folder. I did
a registry search for it and found it inHKEY_LOCAL_MACHINE\SYSTEM\
CurrentControlSet\Services\iaStorV. This made me happy!
Some more Googling later and I figured out t... 阅读全帖 |

发帖数: 48 | 6 我的resume用了res.cls, 发现虽然板式漂亮,但有点太稀疏了,
比如每个section的行间距偏大，文本宽度偏小，不知应该如何进行调整？
res.cls中关于行间距的文本如下：
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% Use this to set the sectionwidth.
% It adjust the width of the text as well as the hoffset
% You probably shouldn't touch any of the size paramaters
% unless you really understand all of this but it is not
% hard. Either way, it can only be executed once
%
\def\sectionfont{\bf}
\newdimen\sectionwidth
\newskip\sectionskip
\newdimen\resumewid |

发帖数: 43 | 8 遇到一个仿真的问题，大致情况是这样的：在layout画了一个two-port network，里面
用ADS Momentum得到的s paramater 然后转化成z parameter.这个转化用matlab 的
function或ADS自带的stoz()都算过，结果是一致的。 然后我把这个layout转化成一个
component, 用于我的一个简单的电路图中。这个电路图里面，我测量两个port的电压
V1, V2，和电流I1, I2，然后为了验证，我带入Z-parameter运算，照理来说应该要V=Z
*I, 可是等式左右不相等，并不是符号不对，而是数值相差太多。
不知道问题出在哪里？
另外我询问了agilent support,他们给了我一段摘抄于他们knowledge center的话，如
下。可我还是不懂，这里说的意思是有两组不同的z-parameter吗？我只听说过open
circuit下算出来的z-parameters.不知道我哪里理解错了.麻烦看看，感谢大家了。

发帖数: 18699 | 9 gibbs sampler要求我们求出conditional distribution of one parameter given 其
它paramaters，这个conditional distribution叫做full conditional
举个例子，假设你有3个parameters a,b,c
而且你可以精确求出a|b,c和b|a,c的conditional distribution,
则sample a, b时可以用gibbs sampler
可是如果你不能精确求出c|a,b的conditional distribution
则sample c时用MH
gibbs sampler因为是没有 rejective sample，
故block technique在gibbs sampler尤为有用
可是MH经常要reject一些sample，所以block常常不那么容易 |
