Mathematical analysis of a discrete fracture model coupling Darcy flow in the matrix with Darcy-Forchheimer flow in the fracture [PDF]
arXiv.org, 2014 We consider a model for flow in a porous medium with a fracture in which the flow in the fracture is governed by the DarcyForchheimer law while that in the surrounding matrix is governed by Darcy's law.

Parametric Taxonomy of Educational Texts
Vestnik Volgogradskogo Gosudarstvennogo Universiteta. Seriâ 2. Âzykoznanie, 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
IEEE 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.

A Normalized Frequency-Domain Energy Operator for Broken Rotor Bar Fault Diagnosis
IEEE Transactions on Instrumentation and Measurement, 2021 In the motor current signal, the characteristic frequency of broken rotor bar (BRB) fault is modulated by the supply frequency and it decreases with the decrease of the load, resulting it to be easily buried under light load conditions.

A spatial epidemic model with a moving boundary
Infectious 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.

When practice needs more research: the nature and nurture of mathematical giftedness
ZDM – Mathematics Education, 2021 The educational literature often includes debate over the nature and nurture of mathematical giftedness. The varied schools of thought reflect discrepancies between views, which are to a large extent functions of philosophical, political, and economic ...
