Definition Of

The paper presents the results study the characteristics of capacitive beating sensors to optimize them by computer simulation tools using. A concentric capacitive sensor with high-potential and grounded electrodes was studied. In the course of the research, the expediency of using computer modeling tools by finite element analysis methods to study the metrological characteristics of sensors was shown. It is shown that the application of modeling makes it possible to reduce the time spent on studies of the transformation function and metrological characteristics. The picture of the distribution of equipotential lines of an electric field in a working backlash of the sensor has resulted. The simulation results make it possible to create a picture of equipotential lines by changing the distance between the total surface of the sensor electrodes and the grounded surface, simulating the surface of the shaft. The results of the definition of the response function are given. References 23, figures 5.

AbstractThis paper introduces some levels at which the computer has been incorporated in the research into the basis of electrocardiography. The emphasis lies on the modeling of the heart as an electrical current generator and of the properties of the body as a volume conductor, both playing a major role in the shaping of the electrocardiographic waveforms recorded at the body surface. It is claimed that the Forward-Problem of electrocardiography is no longer a problem. Several source models of cardiac electrical activity are considered, one of which can be directly interpreted in terms of the underlying electrophysiology (the depolarization sequence of the ventricles). The importance of using tailored rather than textbook geometry in inverse procedures is stressed.

The article presents the results of studies to improve the National primary standard machine for hardness of metals on the shore D scale GET 161-2001, which were performed in FSUE “VNIIFTRI” from 2016 to 2018 in accordance with the technical task of Rosstandart.The improvement was carried out in order to ensure the uniformity of hardness measurements on the Leeb scales. The created new parts of the primary standard machine, which are settings for reproducing hardness numbers on the Leeb scales, are considered. Metrological characteristics of the upgraded and adopted National primary standard machine (GET 161-2019) were investigated, the budget of measurement uncertainty was calculated for reproducing hardness numbers on the Leeb scales.
