A Transient Eddy Current Problem on a Moving Domain. Mathematical Analysis [PDF]

SIAM Journal on Mathematical Analysis, 2013
The aim of this paper is to introduce and analyze a weak formulation of the transient eddy current problem governing electromagnetic forming in the axisymmetric case. The resulting problem is degenerate parabolic with the time derivative acting on a moving subdomain. Because of this, we have to resort to regularization arguments in order to prove

Domain-Specific Languages of Mathematics: Presenting Mathematical Analysis Using Functional Programming [PDF]

Electronic Proceedings in Theoretical Computer Science, 2016
We present the approach underlying a course on "Domain-Specific Languages of Mathematics", currently being developed at Chalmers in response to difficulties faced by third-year students in learning and applying classical mathematics (mainly real and ...

Identifying domain-general and domain-specific predictors of low mathematics performance: A classification and regression tree analysis [PDF]

Journal of Numerical Cognition, 2017
Many children struggle to successfully acquire early mathematics skills. Theoretical and empirical evidence has pointed to deficits in domain-specific skills (e.g., non-symbolic mathematics skills) or domain-general skills (e.g., executive functioning and language) as underlying low mathematical performance.

Analysis and computer implementation of the mathematical model of $180^{^\circ}$ domain structures formation in ferroelectrics

Dal nevostochnyi Matematicheskii Zhurnal, 2022
Summary: The study is devoted to the theoretical analysis and numerical implementation of the 2D mathematical model of \(180^{^\circ}\) ferroelectric domain structures formation within the framework of the Landau-Ginzburg-Devonshire thermodynamic approach supplemented by the Landau-Khalatnikov equation to express the polarization dynamics.

Mathematical analysis of memory effects and thermal relaxation in\n nonlinear sound waves on unbounded domains [PDF]

Journal of Differential Equations, 2020
Motivated by the propagation of nonlinear sound waves through relaxing hereditary media, we study a nonlocal third-order Jordan-Moore-Gibson-Thompson acoustic wave equation. Under the assumption that the relaxation kernel decays exponentially, we prove local well-posedness in unbounded two- and three-dimensional domains.

Analysis of Transcendental Numbers in Various Mathematical Domains

International Journal of Innovative Science and Research Technology
A transcendental number refers to a number that does not fall among the roots of any nonzero polynomial equation with its coefficients as integers. This section encompasses an in-depth literature review to establish a basic understanding of transcendental numbers. Reviewing the historical development of transcendental number theory, the contributors to

Affective domain and mathematics achievement of Colombian students under multiple correspondence analysis [PDF]

Frontiers in Education
The literature review indicates that age is a variable related to the students' affect toward mathematics in such a way that the older they are, the less affection they feel for mathematics. In the case of the Department of Norte de Santander, the administration is going to carry out an educational program for 2050, whose aim is to make this region a ...

An Application of the Caputo Fractional Domain in the Analysis of a COVID-19 Mathematical Model

Contemporary Mathematics
Vaccination programs aimed at preventing the spread of the coronavirus appear to have a significant global impact. In this research, we have investigated a mathematical model projecting COVID-19 disease spread by considering five groups of individuals viz. vulnerable, exposed, infected, unreported, recovered, and vaccinated.
