In the article a possibility is considered as to decrease information features at discrimination of vegetable objects. The multiple discriminant Fisher analysis with step-by-step inclusion of variables was used as an algorithm of discrimination. The infor... see more

A possibility of reducing the number of informative features for multispectral phytogenous data by means of the factor analysis methodis shown in the article. For investigation there were used real reflection coefficients of maize, bristlegrass and ambros... see more

This paper studies the modified Pell polynomials. Some important properties of modified Pell polynomials are presented. An exact formula of modified Pell polynomials derivative in terms of modified Pell themselves is first derived with the proof and then ... see more

Relaxation of the electron energy and momentum densities is investigated in spatially uniform states of completely ionized plasma in the presence of small constant and spatially homogeneous external electric field. The plasma is considered in a generalize... see more

Usually to determine a measure of the degree of ill-conditioning of an algebraic system, we invoke a condition number for the coefficients matrix. In groundwater modeling these coefficients are depending on the parameters of the heteregeneous porous mediu... see more

Wave-particle interaction is a very important mechanism in describing the outflow of ions at high latitudes and high altitudes. Quasi-linear perpendicular velocity diffusion coefficients are used to describe the effect of wave-particle interactions, there... see more
