Hey, thanks for that. I still need to read more about these topics to fully grasp the meaning of your response.
The following is the context, taken from the following paper: http://prl.aps.org/abstract/PRL/v28/i6/p355_1
" It appears from Fig. 3 that weak bonds (e.g, As-As) create localized...
Hello!
This subject has me confused. I hear a lot about Mott transitions and Anderson localization; then in some papers, I read about Mott localization and I'm not sure what they are referring to.
Can someone distinguish the following for me?
1. Mott transition and Anderson transition
2...
Ok. A fit of the function I described to any curve that would best cover the data set I have.
The data set, when plotted, looks like a half ellipse (and is independent of the function).
I need to find the values of the the function's parameters C1 to C4 that would best fit this curve. There...
Hello,
Suppose,
1. I have a function f=C1 + C2/((C3-X)^C4); where Cn is a constant;
I'm looking at the Havriliak-Negami equation which has some 5 constants.
2. I have a data set whose least-squares fit looks like a curve,
How can I compute the values of the function's parameters C1 to...
Hello,
Could you point out a good article(s) covering Perovskite crystal structures? There's plenty of literature out there covering perovskite structures, mostly properties or applications of individual crystals. Googling results are either very specific or too general or complete textbooks...
(Not sure if this is the right forum, but if the admins find a more appropriate one, please do move it over).
Alright, fellow Scientists and Engineers.
I have a Latex question here for you.
I use TexWorks and Lyx when I want to work on Latex, the former when I have .tex templates that Lyx...
Seeing as this thread has had a large number of views, here's the expression that I finally got:
\kappa_{\theta} = \frac{3EI}{L}\frac{tan\theta}{\theta}
The units seem to match.
This is for a cantilevered beam with a force applied at the free end.
When the angle \theta is really...
Just to close this thread for future visitors:

This is a minitutorial for comsol.
Good luck!
Among other things, I'm currently plotting the variation of strain energy 0.5K\theta^{2} with the angle. But I have a limited number of parameters describing the beam, which I believe should be sufficient to get me the torsional spring constant.
Since I have the linear spring constant, I'm...
Unfortunately, I don't have a background in this subject. Not since freshman year in college.
The site that you linked to was good. But I'm not aware of the relationship that you mentioned.
There should be some scientific paper on this subject, if not a basic derivation, that I could use to...
The beam is cylindrical.
I'm trying to understand the effects that various force distributions will have on the beam: from
1) a constant force acting on the free end,
2) a force that varies both across the beam length and across space.
And other force distributions.
But simple cases...
Hello,
This should be a straight one for most of you. Given a cantilevered beam that has a force F applied across it (or at one end), causing a displacement d and deflection \theta , what is the relationship between the torsional spring constant k_{theta} and the linear spring constant k...
Thanks for the reply, Andy. That's a different and a more coherent view describing the various shapes that a drop can take.
That would help describe the slightly elongated shape of droplets on the bristles of a stiff comb or tips of blades of grass.
The next thing to do as a follow up...
Hello,
I'm an Electrical engineering student taking a class on surface chemistry. I've been given a problem where I need to analyse the stability of droplets using Unduloids.
I have some lecture notes on unduloids in the context of this subject and it's quite limited, but every other...
