The mathematical model of the forming of high resolution discrete grid for various configurations of toothing surface of poles of stator and inductor of linear stepping motor. The method of the forming of discrete grid was developed on the base of mathematical model; it takes into account various factors which affect to the accuracy of position of discrete grid nodes. The verification results of mathematical model developed were shown, they confirm the increasing of accuracy of motion systems on the base of linear stepping motors.

Investigated experimentally the principle of propagation of thermal fields in integrated circuits as a result of electrostatic discharge. A numerical model of the temperature distribution in the current-carrying elements of integrated circuits due to contact effects of static electricity, and electrical conductivity based on the Fourier analysis of the thermal conductivity is proposed. The developed model predicts the temperature dependence of the discharge voltage and identify the most vulnerable conductive region by identifying local areas of melting.

Numerical simulation of a family of curves obtained interference immunity for various operating conditions of the generator of chaotic processes is received.

The construction, technology and main features of passive matrix light emitting microdisplays based on reverse biesed Schottki diodes with the structure of nanoporous Silicon-Aluminium are described.

One of the main problems in the secondary radar information processing (trace-while-scan) is the correct identification of sensed plots with corresponding tracks of targets being tracked by extrapolated marks. The proposed extrapolation algorithm is based on the principle of gravity by analogy with the physical phenomena of charged particles attraction. Modeling shows that probabilities of correct identification calculated according to this algorithm significantly higher than the values calculated by the methods of linear and quadratic extrapolation. It shows high efficiency of the proposed attraction method.

The method of coordinates calculation of a flight trajectory of the aircraft, adjusted by the reference points and values of radiuses of circles on which the bend in case of change of a direction of the movement should carry out the aircraft is resulted. It is shown that it’s easier to carry out nessesary calculations in special system of the co-ordinates which position in space is defined by three reference points of a trajectory.

Nonrelativistic equation of motion of the mass point with internal degrees of freedom in scalar potential U depending on time and relative coordinates, and velocity and accelerations is obtained. Equations of motion lead to equation of balance of energy, whose conservation takes place when potential function does not depend on time and accelerations. The equations obtained are applicable to a motion of the electron, spin of which is interpreted from the viewpoint of classical mechanics.
