Autor: Vakulenko Aleksandr, Vakhrushev Sergey, Koroleva Ekaterina, Vasilyeva Evgenia

Publikováno v: St. Petersburg Polytechnical University Journal: Physics and Mathematics, Vol 16, Iss 1 (2023)

In this work, the permittivity measurements of lead magnoniobate PMN (111) single crystals with thicknesses of 400 µm, 25 µm and 10 µm have been carried out at a frequency of 0.1 Hz. The samples in the form of plane-parallel plates were prepared b

Substantiation of the theoretical and methodological approach to planning the work of rolling stock in the conditions of Eastern Siberia

Autor: Vakhrushev Sergey, Trofimova Liudmila

Publikováno v: MATEC Web of Conferences, Vol 341, p 00002 (2021)

The substantiation of the theoretical and methodological approach was carried out as a result of identifying probabilistic indicators that affect the planned performance of the rolling stock and determine the properties of the types of activities for
