When estimating of the wind profile over a slope with a scanning lidar in one scan measurements are performed at different heights from the underlying surface. Therefore to restore the wind profile, we need to use several measurement results of scans. In this paper we present the corresponding algorithms.

The present paper contains a review of the main results of Yerevan research group in tomography of planar bounded convex domains. The applications of these problems are known in both geometric and computer tomography. Complicated geometrical patterns occur in many areas of science. Their analysis requires creation of mathematical models and development of special mathematical tools. The corresponding area of mathematical research is called Stochastic Geometry. Among more popular applications are Stereology and Tomography. The methods of form analysis are based on analysis of the objects as figures, i.e. as subsets of the plane. For these sets, geometrical characteristics are considered that are independent of the position and orientation of the figures (hence they coincide for congruent figures). Classical examples are area and perimeter of a figure. In the last century German mathematician W. Blaschke formulated the problem of investigation of bounded convex domains in the plane using probabilistic methods. In particular, the problem of recognition of bounded convex domains by chord length distribution.

We consider the set Fn,N of all possible forests, consisting of N≥2 ordered non-root trees and labeled vertices. We specify the uniform distribution on Fn,N. When N1/3(n/N−2)→∞ there is obtained the limit theorem for the number of fireproof vertices of one tree in a forest fire model on a random forest taken from Fn,N.

The paper considers the application of stochastic modeling in the study of economic processes. The solution is found in the asymptotic form in the case of several transitions from different states. The transition probabilities are determined by the recurrence formula and after the differential change is converted into economic performance. The main feature of the process – the use of the generating function.
