    Study of kinetic performance effect on wheel and rail wear using computer simulation by Lev I. Evelson, Evgeny A. Pamfilov, Alexander G. Tsygankov, Ludmila I. Shiryaeva

    Published 2016-06-01
    “…The problems solved here are analysis of the earlier proposed mathematical functions describing the kinetic performance for the presence of extremes, the functional behavior (growth, decrease, monotonicity, and unimodality, etc.) in various parameter ranges; implementation of the computer simulation of the wheelpair movement by rail with the quantitative estimation of the wheel and rail wear with various kinetic performance parameters; to determine qualitative influence patterns of the kinetic wear performance. …”

    Algorithm for Finding Feedback in a Problem with Constraints for One Class of Nonlinear Control Systems by Michail G. Dmitriev, Zainelkhriet N. Murzabekov, Gulbanu A. Mirzakhmedova

    Published 2021-10-01
    “…For this, the solution of an auxiliary optimal control problem with a quadratic functional is used by analogy with the SDRE approach.Since this approach is used in the literature to find suboptimal synthesis in optimal control problems with a quadratic functional with formally linear systems, where all coefficient matrices in differential equations and criteria can contain state variables, then on a finite time interval it becomes necessary to solve a complicated matrix differential Riccati equations, with state-dependent coefficient matrices. …”

    Assessment of the significance of factors associated with the development of long-term adverse cardiovascular events in type 2 diabetes mellitus by D. V. Grazhdankina, I. A. Bondar, A. A. Demin

    Published 2022-10-01
    “…Concentration of N-terminal pro-brain natriuretic peptide (NTproBNP) was determined on an Immulait 2000 Siemens analyzer by immunochemiluminescence assay. Glycemic variability was assessed by calculating the standard deviation (SD) and coefficient of variation (CV) of glycemia during the day according to laboratory measurements of glucose levels at least 3 times a day for at least 3 days. …”
