Ah thanks that was what I was looking for. Now I just need to fix how to save in the right format.

Hi I have a question, I have to save to file the matrixs generated by an algorithm in Matlab. So i was wondering if is it possibile and how, to use in the filename a variable of the algorithm. Let's say "i" is the counter of my cicle and i would like to save the matrix generated at every...

If nature can...we can emulate it, as we always did.

Well oil came from somewhere..no? I don't know how oil did generated exactly on earth, but something that involve time ( a lot) and carbon "waste" and some kind of energy. Guess a similar process ( of course faster) can be engineerized if this is worth to do. So i think is possible, but I'm...

The neutrons that are taken in consideration aren't the neutron of nucleus, but "free" neutrons coming from some source.

no i wrote that, but I'm not saying that :-). Anyway should be something about Gibbs-Helmholtz equation, but i don't remeber much about it. So something about chemistry and termodinamics application usually. \left[\frac{\partial \Delta G}{\partial T}\right]_p = -\Delta S...

humm ..looks like entropia. Or may be I'm completely wrong.

Ah yes I'm sorry, statistic is another thing...sorry again for my italian interpretaion of english words.

No, it doesn't count as nuclear reaction. My english is not very good so may be wasn't much clear. I ment that if asobtion and generation ( S) are nill, there still diffusion due to scattering. The text is: "B. Montagnini - Lezioni di Fisica del Reattore Nucleare - Università di Pisa, 1983"

Because diffusion is composed by a sum of different terms, and if your temrs ( assorbtion and generation) that describe the nuclear reaction are 0, there still a term that describe the neutron collision and this term involves the "Flick law" so there still neutron diffusion also without nuclear...

It's statistic! A single electron can't have 2 different energy at the same time, but on a population of milion of electrons emitted by that radionuclide you will know how many ( % ) got a E1 energy and how many got E2 energy and so on from 0 to Emax. I.E. if you use a distribution of human...

Well it's the "law" that explain the neutron flux. It's like ..humm...a space with a high number of moving balls, those will spread around the space to zone where there are less balls, you can see that the moving balls will spread around in zone where there are less balls, this because you will...

Beta- emission, may vary from a radionuclide to another but in general the energy distribution graph looks like the same for every radionuclide, apart for the maximum energy. The spectrum of the Beta emission is continuos due to the random ripartition of momentum and energy between neutrino...

Netronic diffusion explain how neutron will move inside a material, neutrons will move due to a difference of density of neutron from higher density neutron zone to a lower neutron density zone, due to that in a high density neutron zone there will be more scattering collision than in a lower...
