The technique for computing of the turbulent diffusion coefficient vertical component in the context of a mathematical model of admixture dispersion in the surface layer is proposed
The review of resolvability of the beginning-boundary problem describing dispersion of an impurity in turbulent atmosphere, correctness of mathematical models, describing impurity dispersion in atmosphere and Koshi’s problem, the first right problem, the third right problem is given in the article
In the article with the help of a technique, based on discretization initial problem of time variable and the method of basic potentials, is constructed the approximate solution of the second two-dimensional problem for the equation of diffusion with depending on concentration coefficients and source function. The general view of the approximate solution of this problem is reduced. On concrete example convergence of the approximate solution of the problem to the exact is shown
The article provides the review of optimization methods of the securities portfolio. The contents of the securities portfolio is described
Diffusion-convection equation that has been received from Saint-Venant differential equation system describing nonstationary fluid motion in a river canal is investigated. Analytical method is considered for the solution of equation with the fixed factors and finite-difference method is considered for the solution of equation system with the float factors. The results of test calculations executed for a reaches of the river Kuban are presented
