Exploring spectral collocation methods for diffusion models with variable coefficients in heat transfer studies

Partial Differential Equations in Applied Mathematics
The diffusion equation with variable coefficients is widely applied in heat transfer to model the distribution of temperature in materials with spatially varying thermal properties, allowing for accurate simulation of heat conduction in heterogeneous ...

Bernoulli Collocation Method for Solving Linear Multidimensional Diffusion and Wave Equations with Dirichlet Boundary Conditions

Advances in Mathematical Physics, 2017
A numerical approach is proposed for solving multidimensional parabolic diffusion and hyperbolic wave equations subject to the appropriate initial and boundary conditions. The considered numerical solutions of the these equations are considered as linear

Spectral methods for partial differential equations [PDF]

Origins of spectral methods, especially their relation to the Method of Weighted Residuals, are surveyed. Basic Fourier, Chebyshev, and Legendre spectral concepts are reviewed, and demonstrated through application to simple model problems.

Binary spectral collocation method for the nonlinear Fokker-Planck equation

Journal of Algorithms & Computational Technology
A mixed Laguerre-Legendre spectral collocation schemes is constructed for initial-boundary value problem of the nonlinear Fokker-Planck nonhomogeneous equations and the linear Fokker-Planck homogeneous equation by using the Laguerre interpolation functions in velocity, and the Legendre interpolation functions in time, which is a bivariate Lagrange ...

Towards operational assimilation of surface‐sensitive microwave radiances over land at Environment and Climate Change Canada: Investigation of key factors using a 1D‐EnVar framework

Quarterly Journal of the Royal Meteorological Society, EarlyView.
The study evaluates five factors affecting the assimilation of surface‐sensitive Advanced Microwave Sounding Unit‐A (AMSU‐A) radiances over land, including the simultaneous estimation of surface emissivity and the standard set of state variables, to improve numerical weather prediction (NWP) at Environment and Climate Change Canada (ECCC).

Tourism Labor Market and the Attainment of the 2030 Agenda for Sustainable Development Goals: Pending Challenges, Ongoing Opportunities and More Responsible and Inclusive Scientific Research for the Advancement of the Tourism Industry

Sustainable Development, EarlyView.
ABSTRACT Concerning human resources, research in the tourism sector has traditionally focused on a personnel‐managerial perspective rather than a labor market‐condition analysis per se, limiting the examination of its unique working ecosystem and distinct socioeconomic particularities. This has evidenced an apparent thematic research gap in the tourism

Sustainable Healthy Diet Transitions: An Examination of Media Discourse Concerning Beef in the United Kingdom From 2018 to 2022

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

A Note on the Solution of the Von Kármán Equations Using Series and Chebyshev Spectral Methods

Boundary Value Problems, 2010
The classical von Kármán equations governing the boundary layer flow induced by a rotating disk are solved using the spectral homotopy analysis method and a novel successive linearisation method.

Critical Multilingual Language Awareness, Antiracism, and Raciolinguicized Subjectivities in Teacher Education

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 ...

Teaching Through Trauma: English Teachers Navigating Affective Regimes in Post‐Earthquake Türkiye

TESOL Quarterly, EarlyView.
Abstract This study explores how English as a Foreign Language (EFL) teachers in post‐earthquake Türkiye narrated their experiences of loss, survival, and teaching within state‐imposed affective regimes. Drawing on an affective–discursive analysis of Ministry of National Education (MoNE) documents and media texts, the study first investigates how ...
