1. Engineering Resume improvement -- How best to word this experience?

Hi I wrote a code in a specific topic, for example, Molecular dynamics How can I state it in my resume? "Code development of water transport through a carbon nanotube with the molecular dynamics method." "Molecular dynamics simulation of water transport through a carbon nanotube." OR??? If...

for example i want to correlate a curve through the points that i have attached.... https://uploadfiles.io/753a6
3. A Plot a curve through some arbitrary points

I want a sin diagram that decay with time
4. A Plot a curve through some arbitrary points

How can i do it with MATLAB or EXCEL?
5. A Plot a curve through some arbitrary points

Hi how can i plot a curve (red curve at this example) like this:
6. A How to calculate RDF (Radial Distribution Function)

I think for example if we have 3 particles: first we look at bin 1 for all three particles: bin 1 for particle 1: 1 atom bin 1 for particle 2: 1 atom bin 1 for particle 3: 0 atom And so on... we have ##\frac{2} {3} = 0.67## for bin 1 in histogram?
7. A How to calculate RDF (Radial Distribution Function)

I think i should take average over all of particles...??!! What i write is for one particle...???!!!o_O Is it true?
8. A How to calculate RDF (Radial Distribution Function)

Yes i forgot dr in denominator But the formula that i write is not math with #8 My formula has one N but that formula have two N one in denominator and one in ##\rho_0=N/V##
9. A How to calculate RDF (Radial Distribution Function)

particleateachbin=particle at each bin(particles between r , r+dr) totalnumberofatoms=total number of atoms(N)

11. A How to calculate RDF (Radial Distribution Function)

What is the meaning of ##\delta (r-r_{ij})## in the following equation? Before all what is the meaning of ##\delta##?
12. A How to calculate RDF (Radial Distribution Function)

I write the RDF formula: $$g(r)=\frac{\frac{particle at each bin} {4 \pi r^2}} {\frac{total number of atoms} {V total}}$$ But i don't understand why the following link two times divided it by N. I think we should divide by N one time according to the formula that i have wrote...
13. A How to calculate RDF (Radial Distribution Function)

Should i average RDF on all particles? Or RDF is for one particle?
14. A How to calculate RDF (Radial Distribution Function)

I attache my RDF plot is it true? Why it is not smooth? 27 particles in 3.8nm*3.8nm*3.8nm my formula: g=(h(n)*l_x^3)/(n_p*4*pi*((n-0.5)*delta_r)^2*delta_r); h(n):number of particles in bin n_p:total number of particles But this RDF figure form Wikipedia is very smooth: and my first peak is very...
