A systematic approach to multiphysics extensions of finite-element-based micromagnetic simulations: Nmag

open access: yes, 2007
Extensions of the basic micromagnetic model that include effects such as spin-current interaction, diffusion of thermal energy or anisotropic magnetoresistance are often studied by performing simulations that use case-specific ad-hoc extensions of widely

Numerical solution of fractional-order Riccati differential equation by differential quadrature method based on Chebyshev polynomials

open access: yesAdvances in Difference Equations, 2017
We apply the Chebyshev polynomial-based differential quadrature method to the solution of a fractional-order Riccati differential equation. The fractional derivative is described in the Caputo sense.

On the solvability of boundary value problems for linear differential-algebraic equations with constant coefficients [PDF]

open access: yes, 2023
We study a two-point boundary value problem for a linear differential-algebraic equation with constant coefficients by using the method of parameterization. The parameter is set as the value of the continuously differentiable component of the solution at
