In this paper we analyzed the properties of the approximating polynomials, obtained by the method of least squares. It was revealed that with increasing density and uniformity of the distribution of examples on the interval of approximation, the criterion of minimum mean-square error indirectly brings to equality of the integral characteristics of the approximating polynomial and the approximated function. The method has been suggested to parameterize of the approximating polynomials on the basis of this, and the numerical experiments demonstrated advantages.

This paper presents the development of a free-surface three-dimensional oceanographic model, for the use on cluster computers. The s-coordinate, free surface model is based on full nonlinear primitive equations of the ocean. Numerical integration procedure is based on time-splitting method with Robert-Asselin filtering. Parallelism is provided via high-level message-passing routines. The resulting numerical code allows an efficient use of a cash memory to minimize processor-memory data exchange.

This work is devoted to developing tools for the visual analysis of tropical cyclones based on satellite data. The implemented system has an extensible set of algorithms for the loading, processing and visualization of data, mainly the spatial scalar fields. The wellknown algorithms and author's developments using CUDA technology, and shaders were used in creation of visualization system.
The paper compares the formation conditions, crystal structure, conductivity, and thermoelectric properties of thin CrSi and CoSi films on silicon substrates with (111) and (100) orientations. It is found that, despit...

The modes of dynamics of genetic structure and population size are investigated in this work. It is assumed that main population characteristics, such as reproductive potential and survival rate of reproductive part of population in following years of life are determined on genetic level. Our research has shown that despite increasing of average population fitness is followed by arising of complicated dynamics of population size and of genetic structure, further growth of fitness is capable to stabilize the genetic structure of population and so only the population size will be fluctuating with regular or chaotic circling. The type of the final genetic equilibrium depends upon initial conditions in a very complicated way. Therefore the initial conditions play essential role for the evolution of natural population.
