Parametric Taxonomy of Educational Texts

open access: yesВестник Волгоградского государственного университета: Серия 2. Языкознание, 2023
The article is aimed at considering the issue of the discursive text typology and developing a parametric model of the elementary school texts for the ontological domain by employing a corpus-based approach and methods of linguistic statistics.

Development of Fractional Order Modeling of Voltage Source Converters

open access: yesIEEE Access, 2020
This paper proposes a mathematical fractional order modelling of Voltage Source Converters (VSC). Fractional behaviour helps to model and describe a real object more accurately than the integer order model.

Now you see it, now you don’t - Cognitive skills and their contributions to mathematics across early development

open access: yesJournal of Cognition, 2023
A broad variety of domain-specific (e.g., non-symbolic magnitude comparison and arithmetic) and domain-general (e.g., spatial skills and inhibition) skills have been identified as precursors to mathematics achievement.

An extension theorem for regular functions of two quaternionic variables [PDF]

open access: yes, 2019
For functions of two quaternionic variables that are regular in the sense of Fueter, we establish a result similar in spirit to the Hanges and Tr\`eves theorem.

A spatial epidemic model with a moving boundary

open access: yesInfectious Disease Modelling, 2021
We present a new mathematical model to investigate the spatial spread of an infectious disease. The model consists of a nonlinear PDE system with an unknown velocity field, defined on an epidemic domain that changes with time.
