space is 1900sf, but just checked county record and found that it was only

for longer runs in hot and humid condictions, so you know how much you need

It's understandable that some of us have a great sense of it without
actually measure it (like whx), some others (like me) miss the target by
pure "feeling", and would benefit from a more scientific measurement.
I'd think Alberto Salazar was an extreme case, he was lucky to be alive.

标 题: 哪位大虾能给我简要介绍一下Dynamics of Measurement
发信站: Unknown Space - 未名空间 (Mon Dec 22 16:54:10 2003) WWW-POST
我自己看了看书，我的理解就是关于在测量中仪器对输入的响应。不知道这样理解对吗？
我自己在看Physical Measurement and Analysis（Nathan Cook & Ernest Rabinowicz,
Addison-Wesley Publishing,1963）这本书。
书上介绍说所有的仪器的响应基本上都可以归结为两个微分方程。这个我基本能够看懂。
我的问题是，
1）我如果知道这个仪器的响应，这对我的测量工作用什么用呢？
2）我应该如何根据这个仪器的响应去改进我的测量方法？
3）我应该如何利用这个仪器的响应去分析数据？
但是在书上去没有找到这几个问题的答案。请大虾们给我言简意赅的介绍一下。
谢谢！ |

发帖数: 7 | 15 There are several ways to measure the thickness.
Mass method only works for thickness larger than microns.
Ellispometry is the most popular method measure from 1 micron
down to few nonometers as in the case of SAMs. You have to know
some prior info for this technique, like optical constant
of substrate and film (wavelength dependent), which sometimes
is not easy to get. Some widely-accepted assumptions include:
1) for most thin organic film, n~1.45.

发帖数: 994 | 20 The assumption of bounded Lipschitz constant B (B should be something

(2) To prove by contradiction, we can assume (without loss of generality)
that there is a Borel-measurable set D, such that m_n(D)>m(D)+delta,for all
n. (delta>0 is a constant). Then by (1), we can find a open |

Q***5
发帖数: 994 | 21 I think you can prove (1) by the following arguments:
1.1 It is true when A is any open segment -- This is just by defination of
cdf.
1.2 It is true for any open subset of [0 1]. An open subset is just a
uninon of countably many opens segments.
1.3 It is true for any Borel measurable subset A: m_n(A) = inf_{A\subset D,
D open}m_n(D)<= B\inf_{A\subset D, D open}m(D) = B m(A)

Q***5
发帖数: 994 | 22 For (1.3), you can pull a big gun: Radon-Nikodym Thm.
We know that m(A)< B p(A) for any open set. So for any Borel measuable set D
, if p(D) = 0, then D can be covered by a open set, which is of arbitrarily
small measure. As a result, m(D) is arbitarily small, there for m(D) = 0.
Hence m<=0, and h is Borel
measurable, L_1 w.r.t p.
You can prove that h is bounded by B a.e. w.r.t p: otherwise, there exists
delta>0, such that p(E)>0, where E = (h>B+delta), w |

Just took a look at Shreve's book. It doesn't seem to be quite obvious to
show the martingale property though.
For ED futures, let F(t; T1, T2) be the time-t future rate (simply
compounded), from T1 to T2.
Let L(t; T1, T2) be the forward Libor rate.
Then we have F(t; T1, T2) is a martingale under risk-neutral measure, so is
the ED futures price of course.
Moreover, F(t; T1, T2) is the expectation of L(t; T1, T2) under risk-neutral
measure.
Future rates are quoted directly from mark... 阅读全帖 |
