Jacobi rational–Gauss collocation method for Lane–Emden equations of astrophysical significance
Nonlinear Analysis, 2014 In this paper, a new spectral collocation method is applied to solve Lane–Emden equations on a semi-infinite domain. The method allows us to overcome difficulty in both the nonlinearity and the singularity inherent in such problems.

Spectral Filtering for Improved Performance of Collocation Discretization Methods [PDF]
, 2000 Spectral filtering methods are investigated for use in reducing the Gibbs oscillations that result when discontinuous functions are projected onto globally definedtrial function expansions.

Transition of thermally induced flow in a square cavity using Spectral Method [PDF]
E3S Web of ConferencesThis study presents a novel mesh-free method for simulating natural convection in a square cavity filled with Newtonian fluid. The proposed algorithm integrates mesh-free Spectral methods with the Moving Collocation Element (MCOE) technique and employs a

Sustainable Development, EarlyView.ABSTRACT The role of diet in individual and planetary health is increasingly scrutinised as consumers are encouraged to make food choices that balance health and sustainability, particularly with beef. While prior research has considered reduction from the perspective of alternate product acceptance, the social context of beef is less understood. Media

The Unified Transform: A Spectral Collocation Method for Acoustic Scattering
, 2019 This paper employs the unified transform to present a boundary-based spectral collocation method suitable for solving acoustic scattering problems. The method is suitable for both interior and exterior scattering problems, and may be extended to three ...

TESOL Quarterly, EarlyView.Abstract Race and language collaborate in structuring educational inequities, creating urgency for teacher education to equip all teachers to equitably serve racialized multilinguals as antiracist language educators. Emphasizing the inseparability of racial and linguistic justice, this article examines teacher candidates' (TCs') learning journeys ...

Accurate Chebyshev collocation solutions for the biharmonic eigenproblem on a rectangle
Journal of Numerical Analysis and Approximation Theory, 2017 We are concerned with accurate Chebyshev collocation (ChC) solutions to fourth order eigenvalue problems. We consider the 1D case as well as the 2D case.
