In this paper there evaluated occupational risk assessment methodology using mathematical methods of regression and correlation allowing to determine the priority areas for the development of measures to prevent and reduce occupational hazards and occupational risk. The ranking of factors of production is particularly important in conditions of limited resources.

In this paper, basing on the data of social insurance of employees of the coal mining industrial area of the city, using the methods of high-level classical statistics, there is made a conclusion about the future path of accident development, based on the total costs of elimination of this negative phenomenon consequences. © Metallurgical and Mining Industry, 2014.

At the present stage of technical development all complex systems of industrial production and particularly the coal industry require automating of entire process including the work of mining and transport equipment, which can not be done without a detailed mathematical description of specific phenomena characterizing the specific production. Therefore, for the first time to solve the problem of complex technology management, multifactorial systems, it is suggested to use non-parametric statistics, which was not reflected in the national literature. Nevertheless, such mathematical approaches allow to perform correct forecast of the phenomena in question beyond the available experimental data with sufficient accuracy to solve the most practical problems, especially in those cases where the amount of data is relatively small.

In this paper there was developed and implemented a mathematical model of the interpretation of the concept of "risk" with regard to the quantitative and qualitative effects of harmful environmental factors on living conditions, based on the statistical evaluation of the level of accidents coal mine, with the identification of the causes of accidents and construction of distribution function, as well as obtaining necessary statistical dependencies to significantly improve the safety of people.

In the proposed work the advantages and dis-advantages of the known diagnostic techniques errors of IPSP which operates in the modular numeral system are analyzed. Based on the analysis method of parallel correction it was developed that we can improve the efficiency of diagnostics, regardless of the type of computing chains and features of occurrence of errors in it. © 2014 IEEE.

A new principle of phase-locked loop operation is presented. It is based on the specific influence of the phase feedback in oscillator system. The proposed device is a nonautonomous system of weakly nonlinear synchronized oscillators connected in a series with a general negative phase feedback of the first type. The new PLL does not contain a low pass filter and can have a greater fast -response. The phase of its output signal watches the phase of the first harmonic of external polyharmonic signal. The error of tracing depends on the amplitudes and phases of other harmonics. If the external signal includes in addition to first harmonic only second harmonic of arbitrary amplitude the phase error is absent. This PLL can operate with small external signals and filter out their harmonics.

The authors consider the cubature formula for the approximate calculation of triple integrals of rapidly oscillating functions by using Lagrange polynomial interlineation of functions with the optimal choice of the nodal planes for the approximation of the non-oscillating set. The error of the cubature formula is estimated on the class of differentiable functions defined on a unit cube. © 2014 Springer Science+Business Media New York.

The problems of protection and support of openings within unloading zones by the example of Almazno-Marievski mines of Donbass geological and industrial district are considered. Simulation under the mining and geological conditions has been carried out; calculations characterizing effect of unloading zone on extraction working have been performed; diagrams of stresses and deformations with their time progress while extraction pillars mining under longwall advancing gently sloping coal seams have been described. © 2013 Taylor & Francis Group.

In this work the important task of the determining of main necessary competences for vocational schools has been solved. The main steps of curriculums' unitization have been proposed. The basic groups of competences for the specialists of sewing industry have been rationalized. The main differences in competences' formation for the vocational schools were found following the analysis of different Europeans curriculums. Besides that, were proved that diversities complicate middle ranking workers' mobility and possibility of job connection beyond their country significantly. As a result, the alternative variant of competences' allocation has been proposed. © 2015 IEEE.

The determination of the optimal productivity of a screw conveyor vacuum-press molding articles from ceramic green mixes is analyzed. Different variants of productivity determination taking account of the motion of porcelain mix in the press channels and its physical - mechanical properties are presented. © 2010 Springer Science+Business Media, Inc.
