Once I obtain the Ricatti equations to solve the moments equation I can't find the value of the constants. How can I obtain the value of these constants? Have these values already been reported for the titanium dioxide?
It would be better if you give some more details about the equation you are trying to solve. I assume that you are solving the Fokker-Planck equation with a concrete choice of the "drift" and "fluctuation" terms, but I don't know which one you are using.
