✦ Synopsis

By considering two analytical solutions of G. I. for dispersion in homogeneous turbulence, we derive a quantitative upper limit for the timestep d t to IX used in the stochastic Lagrangian model; a more severe upper limit will probably exist in inhomogeneous turbulence. For practical purposes, there is no lower limit to the timestep.

In this paper biological compartmental models are considered which take into account the intrinsic randomness of the transport rate parameters and their possible variability in time. An identification procedure is presented for the estimation of the stochastic processes representing the transport ra
