Abstract

The random fragmentation-advection process is described in terms of generating functional and multiparticle densities. The aim of this article is to connect characteristics of a device performing the measurements of the process at a fixed time with characteristics of elementary fragmentation processes. The measurand is a random number being a symmetrical function of particles distribution at the moment of measurement. This function is assumed to be non-linear, and this part of the article is devoted to development of the general approach to computing of the mathematical expectation of such detector’s reading whereas the next one will discuss the adjoint function approach in connection with solving the inverse problem: defining characteristics of elementary processes by using results of non-linear measurements.
