发帖数: 5564 | 1 受wh那篇“梦中人，陈百强"的歌曲赏析文章的启示，刚才听Stevie Nicks的Landslide
的时候，心血来潮，也写写自己的感受。
Stevie的Landslide是收音机里放得很多的一首歌，想没听到过都难。最初听到的时候，
说实在不是很喜欢，Stevie的声音明显有些老了，显得coarse。
不过，老太太在经历岁月创伤后强烈而又自然的感悟，显然不是年轻人的为赋新诗强作
愁可以比拟；那情绪把我攫住，一时挥之不去，当时真觉得有点depressing。没想到后
来再听几遍之后，慢慢地开始喜欢上这首歌。
后来再听Dixie Chicks唱的版本，就觉得很轻浮很很肤浅，象一幅厚重的油画被轻描淡
写地临摹成了速写。甚至听了Stevie Nicks本人年轻时所演唱的这首歌，觉得相比之下，
还是她年老之后所唱的版本更有味道，充满着那更具渲染力的情绪。她30年前写的这首
歌，简直就是给自己年老之后所作。
不过，即使到今天，我也不知道歌曲确切要表达什么.
我的理解是，在爱的历程中幡然醒悟，不要不切实际地把爱看得太高，不要把爱情当成
高山一样去攀爬，认清真实的自己，让幻灭如山崩，把自己带回到现实。 |

标 题: A question about selecting u,v in a parametric surface
发信站: BBS 未名空间站 (Thu Nov 2 14:03:15 2006)
Dear all,
I have a basic question about the parametric surface. I have a set of
unstructured 3D points acquired by a scanner. A coarse mesh was generated
based on the geometry of the subject that was scanned. Now I want to get a
parametric representation of the surface, but some global fitting is needed
since the data is too noisy.

I don't have first-hand experience with ejb3
so I can't really comment on it.
Although I think that the performance problem
of classic ejbs mostly comes from not the
wiring, but the invocation boundary - all
the marshalling/going over the wire/unmarshalling,
which probably hardly changed in ejb3.
It's not really that bad for stateless session
beans though, their API being very coarse
grained. |

My problem with SOA is not that it recognizes network traffic as a major
issue and tries to address it - that's a good thing. I just don't agree
that the traffic issue has to be addressed at the _interface_ level.
IOW, we can still have OO service interfaces, which have implementations
that take care of aggregating remote invocations and all other sorts of
optimization.
Also, I think the concept of SOA, like many other things these days, is
being abused. It was intended only for coarse graine |

发帖数: 34805 | 13 The service/factory you talk about is not service layer in 3 tier sense. It'
s an aggregation/adaptor layer. Backend services are typically more fine-
grained and you want a more coarse-grained facade then you can do it here.
Say if you have backend services, one to store a user account, one to send
an email. You can assemble these two in this layer and call from various
controllers. |

发帖数: 34 | 18 yes, the matrix is not square
just want to get the least aquare solution.
We already can got the result.
The problem is just time.
now we use the coarse grid, for one iteration it take about 1 day.
usually after 4 or 5 iteration we can see something in the result.
this is just the test version.
we need to try finer grids, it means larger matric inverse.
it may take a few days for iteration fineshed.
that is why we need to find the parallel library.
then we can use multiple processors to do this |

an example, suppose you have a processor and you wish to reduce the
power consumption. One way is to "turn off" when it is idling. The
other way does not simply turn it off but rather can adjust its
frequency and power supply voltage according to how busy the processor
is. so the first method is "coarse-grained" -- a binary/hard control, and
the second one is "fine-grained" -- a continuous/soft control. |

数值模拟绝不是万能的，有些人觉得数值模拟很简单，跑个blackbox就行了，但是数值
方法是有误差的。如果不了解方程解的性质就随便抓个数值算法来，结果往往轻则一无
所获，重则被误导得到错误的结论。举一些例子:
解是否有守恒量？某个泛函是否有单调性？有没有coarse grain limit？如果数值算法
不是特别设计考虑到这些，数值结果还能相信吗？
shock会不会形成？形成以后的解在什么意义下是想要的解？如何能保证数值算法给的就
是这个解？
会不会有湍流，解会不会随时间越来rough，in what norm？如果光滑性越来越差，数值
discretization不够了如何解决？
如果有metastability,有Arnold diffusion (比如NLS就有这个),指数时间之后解才会
变成另一个形式，这个计算时间如何能够afford？
如果是非线性SPDE，噪音discretize了以后得到了数值解，可是真正的SPDE根本没有st
