time scale in brownian force
Just as we know Brownian force is given by this relation:Fb=xi*sqrt(pi*S0/dT) for sub-micron particles .
dT=time scale; Xi=zero-mean, unit variance independent Gaussian random numbers.
My main question is that how time scale(dt) is determined in this formula ?
Another question is how to compare this time scale with time paticle passed on its cell position?
Thanks in advance for any help. M.Asghari
