Chinese method of creating a harmonious environment, feng shui, is also
gaining ground.
Wind and Water
Pronounced "fung shway," feng shui literally means "wind and water." Its
roots are 5,000 years old.
Feng shui seeks to promote prosperity, good health, and general well being
by examining how energy, qi, pronounced "chee," flows through a particular
room, house, building, or garden.
Yin and Yang
Feng shui considers yin, fem |

w*h 发帖数: 286 | 2 今天偶给一位来自巴基斯坦的哥们装一个软件PROE2000,开始
偶以为他是从他们国家带来的,不会装让偶给参谋参谋,是在
他的宿舍里的一台机器。PROE2000软件是美国PTC公司的拳头产
品,用于三维设计,里面集成有FEM,动力学,运动学,CAM的
加工代码自动生成等模块,是现代机械工业中最有力的设计工
具,一般个人肯定是买不起这样的软件。
在偶给他安装的过程中,偶就问他是从那里弄到这个软件的,
他开始就是不说,偶就没有追问。安装完后,他笑着说是一个
国内(巴基斯坦)朋友给带来的,偶心想巴基斯坦也廷发达的,
怎么这样的软件也能搞道,后来偶说中国也有类似的情况,不
过现在正在整顿,趋于好转。最后,他和偶说这些软件是从中
国转买过去的,他的那个朋友就是专门从中国买CD ROM到他们
自己的国家去卖的。偶很是吃惊,中国连盗版的软件也出口!?
其实这些盗版软件已经彻底摧毁了中国的民族软件产业,偶们
只知道用一些关税壁垒来防止国外汽车,农产品等对中国产品的
冲击,怎么就不知道保护具有同样危害于民族软件业的盗版?
只用10块钱就能买来了PROE2000,AUTOCAD2000,谁还用上千的
资金去 |

p********t 发帖数: 54 | 3 constitutive model for softening material is still a heat point in the field
of geotechnical engineering. there is an international conference on softening
every year.
so i dont think it is too old or has been solved totally.
as i know, a paper on the constitutive model that i studying now was publish
in the ASCE in 1995. and there are still some problem on it, such as the
convergence problem when applying the FEM. |

a****n 发帖数: 583 | 4 你是正牌学汽车的,你对此项目的前景如何看待
如果只从制造的角度来说,如果是整车的制造
如车身制造,将带动成型制造学科,焊接学科的整体发展
如果讨论汽车的集成化生产,将带到生产系统这个学科的发展
当然还包括噪声控制,发动机,FEM,材料科学等,
不知道是否真的能实现这么多学科的发展。
我认为就目前的研究还不到市场研究这个阶段,就如德国进行的磁悬浮列车的
研究,三十年的研究才刚刚进入到市场应用阶段。
而燃料汽车,就大学的性质而言,必须走在应用的前面
不能简单认为这个项目无市场前景,就决然放弃项目的研究
实际上的科研成果又有百分之几能真正应用于生活中。

我本科和研究生在国内都是土木,研究生偏向于基坑FEM分析。2年前来到美国,在一个
一般的学校(MSU,大家都知道实力)读2年,按照博士计划进来的,可是现在我除了上
课,科研上什么进展也没有,也就最近去实验室多一些,至少再要2年才能博士毕业。
不过我学习的方向是pavement,更具体的说是fatigue cracking for asphalt pavement,
这个方向就是博士毕业也很难找到工作的,因为我没有GC等,身份问题限制我找工作,就
是博士比别人努力很多,找工作也不行。(别说我去当发考题,我自认为没有这个实力)
如果我要是转专业,一直都是土木方面,而结构方面的东西差不多忘光了,估计经过几
周学习可以达到本科阶段的能力。而这2年我学习了不少固体力学的课程,比如《塑性
力学》《粘弹性力学》《断裂力学》还有基 |

y******r 发帖数: 2986 | 8 Thank you very much for your suggestions.
Right now I can only use ABAQUS, not ANSYS nor other BIG commercial packages
. It seems you want me to study FEM more and manage to find a job in this
field, and
as you said, I did not have much experience, and it seems a little hard to
find
free time for intership, as my advisor is a little push to me. He did not
want
me to work outside in the summer. I hope to find other ways, and thank you
very
much for your suggestions.
Sorry for the late reply.

d****g 发帖数: 325 | 9 也是,大多数android手机厂商必须要做定制手机,依附于运营商销售。
但是Nexus在网上卖,和运营商无关。哪个Nexus比较全?我们可以比较一下。没有一个
手机像iPhone一样可以覆盖所有频段。这个不是高通能解决的,手机集成的时候从射频
芯片到天线那一段的设计是手机厂商做的。高通也不提供PA,FEM和天线吧? |
|
d****g 发帖数: 325 | 10 频段覆盖和基带没什么大关系。主要是射频芯片,功放,FEM前端模组和天线,以及共
存干扰控制的设计。
我不清楚iphone具体是怎么设计的,但是在前端这一块我猜高通也只能提供自家的射频
芯片,和其他厂的元器件一起,提供一个solution。苹果的天线是自己设计的,毫无疑
问。集成的时候还有很多设计,也是需要苹果自己做的,不是拿来放里面就能用。 |

海洋学的ROMS, 有限元的TAHOE。
扯远点,我也想哪天搞个离散元的框架,再跟FEM耦合,再跟CFD耦合,不过个
人的时间精力能力都不允许,感觉这种东西只能是较大的专门的research group
一起干好多年才有戏,也不知这类group怎么搭建起来的。一般都是国家实验室
或著名的民间研究机构才搞得出这类东西,小的机构很难。 |

s********g 发帖数: 135 | 26 小弟做过很多基于machine learning的医学图像(segmentation, tracking),mesh的

现在拿到两个postdoc的offer,一个学校一般,不过是医院,做的是纯粹的CT的重建,
目的是强化重建图像清晰度和减少放射量
另一个学校很好,做的是基于图像的软组织的力学特性建模和流体的simulation
基本上一个是上游:medical imaging,一个是下游:biomechanical simulation
从就业和找faculty 两个方向选择的话,哪个方向比较有前途呢?
