How do I know if the parameter N is big enough? fs has to be be at least 2f, but what about N?
@jsteimel57 9 күн бұрын
Your selection of N is dependent on the frequency you need to resolve, i.e. spectral leakage, so if you need to be able to see frequencies of 0.1Hz for example you must select your fundamental frequency, i.e. 1/T, such that it is at least 0.1Hz, then you can relate your fundamental frequency and period, T=Ndelt, and pick your N value to make sure it gives you your required fundamental frequency. Does this make sense?

Quick comment, there is a mistake in the engraving step, need to make sure operation is cut so it actually cuts and does not just extrude out.

I have no idea how to create Do loops or For loops in Mathematica containing many many many many different functions and operations including plotting within that loop. I've struggled for 6 months, and before that for 34 years (when I entered graduate school in mathematics in 1988) though I did use Mathematica a little bit 1997 to 2000 on a Student License for my Math PhD work. I never figured out how to use TeX or LaTeX after 34 years. It simply does not work.

Are you sure your correction to the relaxation time is correct? Shouldn't the units be seconds? If viscosity is on the bottom, then the unit becomes 1/s.
@jsteimel57 5 ай бұрын
The relation time tau=eta/E and the units of viscosity are Pa.s and the units of E is Pa so that would give units of s and thus relaxation time. Does that make sense?

How you find the composition of liquid which is 0,1 at 4:40 min ?
@jsteimel57 7 ай бұрын
When you have a composition that is in a two phase region you can find the composition of each phase at a fixed temperature by drawing an isotherm to the liquidus or solid phase line on the phase diagram and then trace down to the x-axis of composition to find the composition. For the fractions in each phase you have to use the lever rule which is a bit counter intuitive. Does this make sense?

What is translational and orientational order? I've heard you mention this a few times but I'm unclear on the definition.
@jsteimel57 Жыл бұрын
Translational order effectively means that if I have a basis set and a crystalline material I can find the position of any atom in my crystalline structure via some mathematical operation on this basis set. For orientational order the atoms are all oriented in the same direction in a crystal. Hope this help!
