“…By analysing the test matrix, it is possible to identify the necessary number of additional test points for the differentiation of so-called equivalent defects. Equivalent defects represent faults of the object modules that are indistinguishable using the existing set of test pairs [26,27].…”

The issues of the evaluation and prediction of the reliability and testability of mining machinery and equipment are becoming particularly relevant, since the safety of technological processes and human life is reaching a new level of realisation due to changes in mining technology. The work is devoted to the development of a logical model for analysing the controllability of mining equipment. The paper presents a model of reliability of the operation of mining equipment on the example of a mine load and passenger hoist. This generalised model is made in the form of a graph of transitions and supplemented with a system of equations. The model allows for the estimation of the reliability of equipment elements and equipment as a whole. A mathematical and logical model for the calculation of the availability and downtime coefficients of various designs of mining equipment systems is proposed. This model became the basis for the methods to calculate the optimal values of diagnostic depth. At these calculated values, the maximum value of availability factor will be obtained. In this paper, an analytical study was carried out and dependences of the readiness factor of parameters of the investigated system such as the intensity of control of technical systems, intensity of failures, etc., were constructed. The paper proposes a mathematical model to assess the reliability of mine hoisting plants through its integration into the method of improving the reliability of mine hoisting plants.

“…The findings show that the expense of implementing extensive power storage is contingent upon the specific use of the apparatus and often necessitates substantial initial financial outlay. Malozyomov et al explore an autonomous power supply system fueled by RES to establish an SES [35]. It is emphasized that achieving sustainable economic growth necessitates using RES logically and deliberately.…”

The shift towards a low-carbon society relies on electrifying Renewable Energy Sources (RES). Energy projects have led to an increase in social divisiveness in certain countries. Hence, worldwide, governmental, and legislative entities -local, geographic, national, and global -exhibit significant apprehension over the environmental consequences and risk elements that shape the energy paradigms. Therefore, to mitigate and restrict the problems related to environmental insecurity, the globe must take prompt and efficient measures to safeguard the climate for a more promising future. It must actively seek alternate energy options while decreasing its reliance on petroleum-based energy sources. In light of this pressing matter, this research aims to showcase the capabilities of several RES, such as wind, solar, hydroelectric, and biomass. The research briefly summarizes energy-related issues and prospects, followed by a comparative analysis of RES and non-RES. A comprehensive overview of several Sustainable Energy Sources (SES), such as wind, solar, hydroelectricity, and biomass, is provided, accompanied by pertinent illustrations and statistical data on the global energy potential of each source. The paper addresses risk factors, offers closing observations, and presents future guidance in its final sections.

This paper is devoted to the study of CMOS IC parameter degradation during reliability testing. The paper presents a review of literature data on the issue of the reliability of semiconductor devices and integrated circuits and the types of failures leading to the degradation of IC parameters. It describes the tests carried out on the reliability of controlled parameters of integrated circuit TPS54332, such as quiescent current, quiescent current in standby mode, resistance of the open key, and instability of the set output voltage in the whole range of input voltages and in the whole range of load currents. The calculated values of activation energies and acceleration coefficients for different test temperature regimes are given. As a result of the work done, sample rejection tests have been carried out on the TPS54332 IC under study. Experimental fail-safe tests were carried out, with subsequent analysis of the chip samples by the controlled parameter quiescent current. On the basis of the obtained experimental values, the values of activation energy and acceleration coefficient at different temperature regimes were calculated. The dependencies of activation energy and acceleration coefficient on temperature were plotted, which show that activation energy linearly increases with increasing temperature, while the acceleration coefficient, on the contrary, decreases. It was also found that the value of the calculated activation energy of the chip is 0.1 eV less than the standard value of the activation energy.
