The technique consists in forming a drop of distilled water on the surface of the substrate under study, photographing the drop and using the resulting image, determining the relative roughness and degree of contamination of the substrate with organic impurities. The operability of the technique has been experimentally proved using the example of substrates made of glass, glass-ceramic and silicon. The deviation of measurements of substrate contamination measured by the proposed method relative to the data obtained by atomic force microscopy does not exceed 3 %. The technique allows, while increasing the accuracy of measuring the degree of contamination, to reduce the time of this control, while ensuring the safety of the controlled substrates. At the same time, to reduce the time of using specialized equipment for the purpose of monitoring the degree of contamination of the substrates.","PeriodicalId":432853,"journal":{"name":"Kontrol'.

This is, for example, the determination of modes that provide the highest productivity or efficiency, or minimum tool wear, while ensuring the necessary roughness and accuracy of the product. In the present work, it is proposed to supplement the parameters monitored in electric discharge machining with non-electrical parameters, which include the parameters of vibroacoustic signals that accompany the working process. The paper shows that parallel recording of the discharge current vibration signals makes it possible to reveal the drawbacks of processing conditions and to influence purposefully the technological process modes in order to bring the processing conditions closer to the optimum ones.","PeriodicalId":432853,"journal":{"name":"Kontrol'.

The main error of reflectometers is the methodological component, which is determined by the error of setting the phase velocity of the pulse. The phase velocity of the pulse depends on various external factors. The instrumental component of the error is due to the instability of the reflected pulse shape and the presence of noise in the signal. Based on metrological analysis, an intelligent reflectometer was developed for monitoring overhead power transmission lines. The developed reflectometer contains blocks and nodes to compensate and reduce the main components of the total error. The developed reflectometer makes it possible to increase the accuracy of determining the accident site and reduce the recovery time of the line, and, consequently, increase the reliability of power supply.","PeriodicalId":432853,"journal":{"name":"Kontrol'.

The authors consider the characteristics of oil flow, trunk pipelines and trends in the oil industry. They analyse viscometric methods from the point of view of the control of trunk oil flows. The authors evaluate the methods, on the basis of which they make recommendations for their modernisation for the control of main oil streams. The research showed the absence of a method that meets all the requirements of the main oil flow and the trends of development of the oil industry. According to the authors it is necessary to make further research of measuring methods based on piezoelectric elements and capacitive sensors and possibly implement them in new oil pipelines.

Resultant diagrams are made for various deformation types on crack edges, to be used to determine wave length and frequency of natural oscillations in a plate against a preset inadmissible crack length, thus enabling crack detection.
