STUDY OF WATER INFILTRATION INTO CEMENT-BASED MORTARS USING REAL-TIME THERMAL NEUTRON RADIOGRAPHY
(Eurasian Physical Technical Journal, 2020)Water absorption into cement mortar with different water to cement ratio was studied using neutron radiography in order to assess the durability and stability of these mortars. While the samples absorb water, neutron radiography images were acquired regularly as the absorption time elapses. The time evolution of water front position or penetration depth and the water content ...2025-01-27 -

Study of the Process of Packet Arrival at a Multiservice Node
(Symmetry, 2022)The paper considers the main ways of describing the process that characterizes the arrival of packets to a multiservice node of a telecommunications network. The features of the process under consideration are best represented by the cumulative distribution function A(t). It determines the distribution of the interval size between the moments of arrival of neighboring packets ...2025-01-27 -
Study of the Mechanisms of Radiation Softening and Swelling upon Irradiation of TiTaNbV Alloys with He2+ Ions with an Energy of 40 keV
(Materials, 2023)This paper presents simulation results of the ionization losses of incident He2+ ions with an energy of 40 keV during the passage of incident ions in the near-surface layer of alloys based on TiTaNbV with a variation of alloy components. For comparison, data on the ionization losses of incident He2+ ions in pure niobium, followed by the addition of vanadium, tantalum, and ...2025-01-27 -
