    • About Possibility of Remote Diagnostics of the Respiratory System by Auscultation 

      Zaitseva, E. G.; Chernetsky, M. V.; Shevel, N. A. (БНТУ, 2020)
      Development of technical base, software, accumulated information on the diagnosis of the respiratory system provided the prerequisites for creating remote diagnostics of the human respiratory system through auscultation. The known methods do not solve the problem of determining auscultation points at patent´s housing without a diagnostic specialist. The purpose of this study is ...

    • Assessment of Temperature Effects in Interior Orientation Parameters Calibration of Optoelectronic Devices 

      Starasotnikau, M. A. (БНТУ, 2020)
      A digital micromirror device (DMD) micromirrors periodic spatial structure is a measuring scale in interior orientation parameters calibration of optoelectronic devices problems, when using a DMD as a testobject. It is important that DMD micromirrors periodic spatial structure remains constant. Change in a DMD micromirrors spatial structure may occur due to heating. In addition ...

    • Surface Eddy Current Probes: Excitation Systems of the Optimal Electromagnetic Field (Review) 

      Halchenko, V. Ya.; Trembovetskaya, R. V.; Tychkov, V. V. (БНТУ, 2020)
      Development of technical tools with improved metrological and operational characteristics is the actual problem of the eddy current testing. Ensuring the optimal distribution of the electromagnetic excitation field in the testing zone carries out confident detection of the defects and determination of their geometrical parameters by means of eddy current testing. The purpose of ...

    • System of Laser Monitoring of Water Pollution with Application of Relative Description of Signal Shape 

      Alekseev, V. A.; Yuran, S. I.; Usoltsev, V. P.; Shulmin, D. N. (БНТУ, 2020)
      As a rule, the wastewater treatment system is not designed to filter substances formed, as a result of beyond design basis accident. The nature of the beyond design basis accident is associated with the shortterm appearance of a clot of these substances in wastewater, determined by the volume of the substance storage tank. Therefore, a rational approach is to divert this portion ...

    • Tests of Impregnation Speed of Electrotechnical Pressboard with Insulating Oil 

      Kozak, C. (БНТУ, 2020)
      The paper presents a new test stand for ivestigating the rate of penetration of transformer oil through electrotechnical pressboard. The stand consists of a pipe, to the lower end of which is glued a pressboard plate. The pipe is filled with insulating oil. A mirror is placed under the plate, which directs its image to the lens of the camera, which takes a series of photographs ...

    • Реализация спектрального метода определения динамических характеристик средств измерений 

      Сабитов, А. Ф.; Сафина, И. А. (БНТУ, 2020)
      Основным требованием спектрального метода определения динамических характеристик средств измерений (СИ) является установление амплитудного спектра сигнала в его информативной части, включающей значение амплитудного спектра на нулевой частоте. Существующие низкочастотные анализаторы спектра имеют рабочий диапазон частот, лежащий выше нулевой частоты, что приводит к погрешности ...
