By means of the software Maple, we obtain solutions of the problems of the nonlinear dynamics of a solid body with fixed point (a spherical pendulum) under the action of forces between a magnetic dipole of the pendulum and ...

Basic statements of the theory of the approximation of ordinary differential operators by other ordinary differential operators are given. Approximating operators are not the equal on the given system of functions (functional ...

An approach to the computer simulation of a thermo-mechanical behavior of magnetically hard ferromagnetic solids subjected to quasisteady electromagnetic fields is considered on the basis of the proposed earlier mathematical ...

The influence of temperature of a processable substrate on the strength characteristics of coverings obtained by the method of ESA is investigated by using the microstructural microdurometrical analysis. It is established ...

We consider a new class of evolutionary equations with operators constructed by non-smooth homogeneous symbols. The theory of the Cauchy problem with initial conditions which are generalized functions of the distribution ...

A possibility for the ceramic coating deposition using the laser-microplasma technique without the preliminary abrasive jet machining of the part surface is demonstrated. The coverings obtained have high cohesive resistance ...

Rare earth element (REE) abundances in clinopyroxene and garnet from xenoliths entrained by kimberlites of the Kaapvaal craton, South Africa, and the Somerset Island, Canada, show a strong and species-dependent variation ...

The influence of the general hydrophobicity of aliphatic amines on the distribution between water and surfactant-rich phases at the cloud point temperature is investigated. The possibility of the separation of amines into ...

This article is devoted to solving the new extremal problems on non-overlapping domains with free poles on rays and to the generalization of some results known before.

For a system of (n – 1) polynomials in n variables, we consider the connection of the operation of generation for the root functionals with root polynomials.
