FRIENDS


ChenZhuoqun A little girl who I know in my first tennis class. Although we seldom see each other after the class, I know she is one of my most important friends in PKU( I hope she treats me the same way). She will go to Edinburgh University for her Master's degree.

ZhengYichen A fashionable, graceful girl, who have very good temper and wonderful taste of beauty. My best friend in PKU, though I know her for only 1 year. She will go to Tsinghua University to continue her study.

FuZhendong A handsome guy in my lab, who looks much younger than his age. Polite and cool.

CuiCui An emerald, a precious stone that I will keep in the deepest domain of my memory forever.

YeYing A pacifist. A girl who behaves like a peaceful water in a lake.She cares for her friends in a imperceptible way, like timely rain in the spring. However, without analgetic it also hurts when she pulls your teeth out. She will become a dentist.

HeHui A tall, handsome, and strong high school classmate. A very kindboy who is always prepared to serve others. Very assiduous and ambitious man who will continue his graduate study in Biochemistry. A loyal friend.

WangKang A very good partner, for application, tennis, swimming, almost everything. A very responsible man, warm-hearted, eager to help others. Laugh a lot, but sometimes may feel grum. He makes all his things highly ordered. I think he is a born leader.

ChangJun A girl with great patience and persevererence. A high school classmate who helped me a lot in my most difficult time. She treats me as her most important friend. I think I really really owe her a lot.

HeWei A genius for almost everything except singing(who keeps silent most in KTV). Very smart, very handsome, very socialable. I would surely chase him if I were a girl.

WeiLai A small smart guy, who is friendly to everyone. Quite sociable.Always behaves in a funny style, but sometimes causes nausea. He is a practical person, but always fond of daydreaming, especially for women:)

LiXin My high school deskmate. A small and cute girl who looks even smaller when she pouts. But in fact she is a little older than I, so she calls me little brother:(. She is now working in Beijing. She cares for me a lot.

ShenBin One of my best friend in high school, who has gone to Swiss after graduation for a degree in management. We used to play pingpang a lot. A literature lover and writes and speaks in a good style.

HuQi A big guy, very big, and also handsome. Even his girlfriend is taller than I. Super optimist, who knows everything about how to enjoy life. A lover of classical music and all kinds of sports. He always has a good appetite and enjoy everything he eats

MFEM is useless

The boss said: MFEM is useless. So I'll focus on Hagland's "corner-velocity interpolation".

Two approch for streamline tracing in unstructed grid

这方面工作目前读到的主要有Stanford的Matringe和University of Bergen的Hagland。
第一种方法源自于Pollock方法，最初Pollock方法严格说来只能用于rectangular elements和diagonal permeability tensors，经过几何影射可以用于quadrilateral。这一方法的核心在于velocity interpolation inside the element。简单的一阶线性的interpolation满足divergence=0的性质，但会有较大误差。
第二种方法来自Mixed FEM。这应该是一种更为自然的方法。MFEM同时解出了Pressure和velocity。使用Raviart-Thomas (RT0) 或 Brezzi-Douglas-Marini (BDM1) element可以直接进行streamline tracing。对三维问题理论上会有难度。
就现行的商业FD simulator来说，只有第一种方法可行。第二种方法必须要基于FEM的simulator才行。但实际上对第一种方法而言，velocity interpolation的根基应该还是RT0和BDM1。

Dual Monitor

Windows vista has no problem. Just plug in and use. For Ubuntu, originally I used a small script to change the configuration file /etc/X11/xorg.conf accordingly and restart X to obtain several options. see
http://ubuntuforums.org/showthread.php?t=361124
In fact, by using nvidia-settings I can change the display configuration as easily as in windows. First plug in monitor cable, then being root, type
$nvidia-settings
A configuration GUI will pop up. I can disable/enable any monitor as I want and apply changes immediately without restart X. Good thing, Nvidia!

Dual boot: Vista+Ubuntu

I have reinstalled vista and ubuntu in my Dell XPS 1330 last
week. Here is a little note for future reference.

Configuration history of myDell XPS1330

shipped with vista preinstalled. Patition as follows
1: Dell Utility. Small partition less than 100Mb
2: Recovery. 10Gb
3: OS. Vista installed
4: Media Direct. 2 Gb
I used vista's own disk management tool to shink the OS drive to about
80Gb and used the left space for ubuntu installation. After ubuntu
installation, grub setting was OK. Dual boot was good.

Wanted to get rid of 10Gb recovery and wanted to seperate the system
partition and data partition for vista.

Reinstall vista and ubuntu

First the installation DVD of vista has serious bug when partitioning
the hard drive. Used Media Direct installation CD to partition the hard
drive. Prepare C: and D: drive besides Dell Utility and Media Direct
drive. C: is 40Gb for vista installation. Then install vista in drive
C: using the installation DVD without changing the partition. Install
vista as instructed.

After vista is installed suscessfully, boot into vista, partition D:
drive into another 2 partitions. One is 80Gb and formatted with NTFS,
the rest 35Gb was used for Ubuntu intallation.

Use Ubuntu live CD to install ubuntu. Use 5Gb for swap from the 35Gb
partition. Use the rest 30Gb for linux installation formatted with
ext3. Mount the windows OS partition and windows data partion to
/windows and /windata. No need to mount the other partitions.

After Ubuntu installation, the grub should be configured correctly and
dual boot should be good. I customized the grub menu by booting into
Ubuntu and editing the grub configuration file
/boot/grub/menu.lst. Move vista to the default system to boot.

Peaceful night

I know,

Roses are in full bloom tonight,

For peace and perfume,

Have filled in my little room.

And moonlight ripples softly in my window.

Thank you my Lord,

For giving me the strength,

To forget the daily trifle things,

And enjoy the harmony and wholeness,

Of this universe created by your hand,

And your love.

崭新的月亮

天空的月亮啊，

是崭新的了。

自从和你在窗前寻觅，

它的影，

就是你的影，

而它的光里，

有你的眼睛在看着我。

当云儿遮住它的时候，

我知道你已经睡着了。

给你

天边的彩虹给你，

清晨的露珠给你。

我不再需要甜言蜜语，

因为我的心都已经给你。

我要驱走你迷幻的疑虑，

让你重新拥有爱的希冀。

我要用温暖的光照耀你，

让你不再畏惧暴风骤雨。

不要怕欠我的偿还不起，

爱的账簿早已被我丢弃。

即使最后受伤的是自己，

也无法找到悔恨的依据。

我只希望这么一天，

你我都已容颜老去，

我们还能拉着手默默相视，

了解生命是怎样连在一起。

我的微笑

你轻盈地走过，

带来温柔的风，

轻抚着我的每一个微笑，

给了它生命，

让它舞蹈。

看你拨弄琴弦，

耳畔余音袅袅，

打动着我的每一个微笑，

给了它生命，

让它舞蹈。

我命中注定要这样对你微笑，

不管你是否能看到。

我愿意就这样对你微笑，

没有什么能如此美妙。

啦啦啦。。。

我的微笑，

啦啦啦啦。。。

我的微笑，

微笑！

为什么不能做小孩？

你说我的胡子都老长老长了？

没错！

可是你看小花猫，

它的胡子也好长呢！

为什么不能做小孩？

你说我的背像背了一口大铁锅？

没错！

可是你看小乌龟，

它的背也拱得老高老高呢！

别了

采摘的花儿

香味已经淡去

带不走

也留不下

别了

天边的彩云

梦里的衣裳

脱下了

再也穿不上

别了

我的月牙儿

本就消瘦的脸庞

又被愁云

锁住了光芒

别了

我的小黄鹂

已经学会觅食的你

天一亮

就飞去了吧
