发帖数: 86 | 12 A lot of people talked about Rent VS Buy. I think numbers should help us to
get more feeling about the situation. So I made a load calculator in excel.
And a simple analysis of Rent VS Buy. You can play with it by yourself. It has
a macro. CTRL + P to refresh the calculation.
There are several assumptions. All assumptions are risk. Buy or rent is
actually depended on how you manage those risk. For me, if you live there long
enough (about 10 years, I don't think 5 years is long enough right now). |

But just found that the number is less than the money I paid for appraisal
fee. (check is $308, but I paid appraisal fee $325).
It has a calculation formula (seems there are some number from the HUD).
Just wondering how the cost is calculated?
What's the meaning of normally said "no cost refinance"?

发帖数: 34 | 33 For liquid (polymer in solutions) or crystal sample?
For polymer in solutions, the calculation for concentrated and dilute sample
are different.
Typcially, for concentrated samples, the so-called structure factor will
pollute your scattering profile. (Well, some people may like this
structure factor if they want to study the interactions.)
For dilute sample, things will be much easier. However, you still need
to have an idea of the conformation of your polymer before the calculation.

For low angle scattering like SAXS or SANS, with SLD, you do not need detail

the different surface, for example, cylindle holes, etc., in order to
calculate the intensity with SLD.
For scattering technique, everything is about contrast.
Once you have a surface, there is scattering.
You need to know all the information of the surface which has contrast to |

发帖数: 1651 | 40 Theoretical work is not easy at all! Usually I assume theoretical is so
simple and only need to devise a model and give one input file. as long as
you can reasonably explain whatever those output, you are done! It is not
in this way at all!
When we devise any model, first thing is that we need optimize structure?
compare the structure with experimental one, if they are close enough, then
we can claim it is ground state.
then use this optimized structure to calculate other properties? |

cluster. If it's in that case, you could first determine the different energy
scales of the system. Such as, what's the vibrational energy and rotational
energy scales. You know, generally the vibrational energy is 10 times larger
than the vibrational energy, and so, you need to calculate the lowest
vibrational energy level.
You need to explain what you want to do in detail. The question is too general
and vague now.
