Abstract This paper deals with mathematical modeling of mold growth on wood. The logistic equation is used to model phenomena in changing environmental conditions. Microscopic coverage fraction the represent development a material surface over time. current state-of-the-art dynamic Finnish as reference for model. optimal values coefficient are estimated by simulations under constant conditions ...

Abstract We modeled biological growth using a random differential equation (RDE), where the initial condition is variable, and rate suitable stochastic process. These assumptions let us obtain model that represents well process observed in nature, only few individuals of population reach maximal size species, curve for every individual behaves randomly. Since we assumed assigned priori density,...
