In this paper, the problem of head pose estimation is described. The solution consists of several stages. The clustering is a critical step. The clustering of feature points of the image is consuming and important step that needs to simplify and speed up. For this task, it is proposed to use the properties of a random walk on the graph. The random walk can lead to a measure of cluster cohesion. This approach is closely related to spectral graph theory. The paper presents formulas, steps of the algorithm and an example of calculations. Experiments and comparisons are made with the closest analogue, the method of normalized cut.

The fast algorithm for wheel and rail conformal and multipoint contact modeling is developed. The algorithm for solution of the normal contact problem does not require calculation of the integrals therefore CPU time is decreased. The FASTSIM algorithm is used for solution of the tangential contact problem. Results of solution with the fast algorithm application are compared with the results obtained by using finite element method.

Scientifically substantiated new method for relaxation of residual stresses in the ring parts by high-cycle loading is given. On the basis of the energy approach developed a mathematical model describing the mechanism of relaxation of residual stresses in the ring parts in the multicyclic loading. This model takes into account the geometrical dimensions of the part, physical and mechanical properties of the material and technological modes of processing. We received an analytically expression defining vibro-mechanical processing time, required for the complete removal of residual stresses in the ring parts. It has been established that exceeding the specified time leads to an accumulation of residual stresses until the onset of destruction of products. Experimental studies that describe the change in the internal stress in the multicyclic loading are conducted.

Intensive underground mining leads to land subsidence and collapses. The paper shows an integrated approach to monitoring on the example of the Karaganda coal basin, including calculations of the displacement of rocks, leveling of profile lines and satellite radar interferometry. It is proved that satellite radar interferometry provides reliable measurement results of surface subsidence in mining areas and can be used for monitoring.

On the basis of the eddy-current transducer (ECT) of transformer type sensor has been developed. It allows exploring metal-insulator-metal, aluminum-magnesium alloy structure and titanium. Block diagram of the sensor, basic technical information were presented (the number of 10-130 turns, the value of initial magnetic permeability of the core μmax=500). The scheme of computer application as a generator and receiver of signals from the windings has been considered. Measurements technique which allows high-precision control of defects in composite materials, titanium and aluminum-magnesium alloy has been described. As a part of the study, the transducer has been tested at a number of facilities: aluminum-magnesium alloy 5.5 mm thick and titanium 5 mm thick. The article shows the dependence of the (ECT) signal from the defect in these structures.

The mathematical and physical modelling are shown to be required to investigate temperature condition of traction induction motors on locomotives. The physical model of traction and auxiliary drive of locomotive developed and constructed to investigate the thermal and electromechanical and control processes is presented. The technique and results of experimental investigation of thermal processes of heating and cooling in the 14 kW induction motor fed by frequency converter with scalar control and IR-compensation under the low values of the stator current frequency and rotor speed are presented. The rotor squirrel-cage rings of the induction motor are determined to be most stressed by overheating under the stator current frequency closed to null, the stator end winding on the side opposite to air supply becomes the most overheated unit of the induction motor under higher values of the stator current frequency.

This paper deals with power quality increasing problem in power supply systems of industrial enterprises with intensive spread of nonlinear load, including machine-building enterprises. The usage of shunt active filter as a kind of active correction system for power quality increasing is presented in the paper. The proposed algorithm of harmonic determination and elimination for shunt active filter is described and justified by means of mathematical modeling and computer simulation. A mathematical model of generalized industrial power supply system of machine-building enterprise with nonlinear load was developed within a Matlab Simulink software environment for this purpose. In process of simulation the efficiency of proposed algorithm is shown in different modes of harmonic compensation. The proposed model also can be used for harmonic emission evaluation when choosing proper technical decision for power quality rising.
