Abstract

The paper presents a novel approach to the solution of a moisture transfer problem described by a differential equation with the coefficients which are treated as random processes. The distribution of the projections of the instantaneous velocity vector is approximated by the Vaga-Ising law, and the parameters of such distribution are identified based on a bionic model of adaptive search behaviour. Explicit expressions for the expectation and the second-moment function are obtained.
