    • Структуроскопия витков пружин после высокотемпературной механической обработки на основе измерения скорости рэлеевских волн 

      Муравьев, В. В.; Гущина, Л. В. (БНТУ, 2022)
      Для изготовления рессорных пружин подвижного состава (вагонов, локомотивов, автомобилей) применяют прутки из пружинных сталей. При высокотемпературной механической обработке при навивке пружин и их закалке возникает различие в скоростях охлаждения внутренней и наружной сторон витков пружины, что приводит к различию в структурном состоянии и сказывается на долговечности пружин. ...

    • Dynamic Features of Spectra of Single and Quasi-Periodic Measuring Signals 

      Suchodolov, U. V.; Isaev, A. V.; Sheinikau, A. A. (БНТУ, 2022)
      Solving the problems of spectral processing of single and quasi-periodic signals in measurement and diagnostic systems is directly related to their isolation against the background of external interference or noise. The purpose of this work was to study single and quasi-periodic signals, i. e. signals limited in time, presented as separate components; development of a mathematical ...

    • Probability of Erroneous Data Registration in a Single Photon Erasure-Type Communication Channel with a Receiver Based on a Photon Counter 

      Timofeev, A. M. (БНТУ, 2022)
      When measuring low-power optical signals, it is necessary to ensure the highest reliability of the received data, which is especially important for single-photon communication channels. This determines the expediency of using photon counters as receiving modules for such channels. They are highly sensitive, but are characterized by data recording errors. Therefore, the purpose ...

    • An Approach to Monitoring of Magnetic Parameters of Cores of a Chain of Spheres. Diagnostics of Different Chain’s Length and Core’s Radius 

      Sandulyak, A. A.; Sandulyak, D. A.; Gorpinenko, Y. O.; Sandulyak, A. V.; Ershova, V. A. (БНТУ, 2022)
      The basic structural elements of the magnetized granular medium (effectively used, in particular, in apparatus of thin magnetic separation) are granule chains (according to channel-by-channel model), in connection with which there is a need to detail the features of their magnetization. The purpose of the work is to develop and implement an approach to measuring magnetic (micro)flows ...

    • Influence of Cylindrical Shield Dimensions on Shielding Effectiveness 

      Kanafyev, O. D.; Trukhanov, A. V.; Zubar, T. I.; Grabchikov, S. S.; Panasiuk, M. I.; Kotelnikova, A. N.; Fedkin, V. А.; Fedosyuk, V. M. (БНТУ, 2022)
      Study of dimensional parametersʼ influence on shielding properties of cylindrical shields will allow to optimise the fusion process, as well as to reduce production costs by reducing the material used. The purpose of this work was to compare results of theoretical calculation of shielding effectiveness of an infinite cylindrical shield with the data obtained in real conditions. ...

    • Diffuse Reflectance Spectrophotometers Based on C12880MA and C11708MA Mini-Spectrometers Hamamatsu 

      Firago, V. A.; Levkovich, N. V.; Shuliko, K. I. (БНТУ, 2022)
      Diffuse reflection spectroscopy with spatial resolution is a promising direction of non-destructive control of the properties of a number of scattering fine-dispersed materials, including food products. It can find wide practical application only in the presence of compact, easy-to-use and inexpensive spectrophotometric equipment. The aim of the article is to investigate the ...

    • Prediction of Dynamic Characteristics of Thermocouples with Thin-Wire Sensing Elements 

      Safina, I. A.; Artemyeva, S. A. (БНТУ, 2022)
      Thermocouples dynamic characteristicsʼ prediction is one of the relevant directions in the field of dynamic measurements of non-stationary temperatures of liquid and gaseous media. Thermocouples dynamic characteristicsʼ prediction makes it possible to provide effective continuous correction in automatic control systems for non-stationary temperatures. The purpose of this paper ...

    • System Eliminating Emergency Discharges in Industrial Facilities Waste Waters Using Relative Signal Description 

      Alekseev, V. A.; Yuran, S. I.; Usoltsev, V. P.; Shulmin, D. N. (БНТУ, 2022)
      Peak emergency discharges of harmful substances to the industrial companies waste waters that normally form coagulates over time present a serious environmental problem. These coagulates can enter natural water bodies during the wastewater discharge. Thus, detecting these coagulates in real-time is a relevant problem. To solve this problem, the authors suggest building an automated ...
