Popis: | Space- and time-dependent stochastic processes can exhibit correlated spatio-temporal fluctuations, which in special cases can be interpreted as the velocity of the process. We show how for a certain class of such processes - time dependent two-dimensional stochastic patterns - this velocity can be determined experimentally. Since the experimental method is based on differential properties of the pattern, we have calculated the joint distribution function of these quantities for a common type of circular Gaussian process. |
