    Analysis of hydromagnetic Williamson fluid flow over an inclined stretching sheet with Hall current using Galerkin Weighted Residual Method
    (Elsevier Ltd, 2023-06-18) Adebowale, Martins Obalalu; Sulyman, Olakunle Salawu; Olalekan, Adebayo Olayemi; Olusegun, Adebayo Ajala; Kazeem, Issa
    The current theoretical work addresses the Hall effect on three-dimensional non-Newtonian fluid flow past an inclined stretching sheet using a numerical scheme. The model also accounted for the impact of chemical reactions, activation energy, solar radiation, and heat generation or absorption. Therefore, the study is organized to examine and enhance energy efficiency. To achieve the model’s aims, the Galerkin Weighted Residual Method (GWRM) was adopted. The graphical findings revealed that: heat sink has a low thermal efficiency between 4.4% and 5.0% than heat source. Also, the Williamson fluid flow decreases via the magnetic field due to the Lorentz force in the opposite direction of the flow. Furthermore, the current work finds application in wire coating technology.

    Shifted Chebyshev Approach for the Solution of Delay Fredholm and Volterra Integro-Differential Equations via Perturbed Galerkin Method
    (Azad University, Rasht, Iran, 2019-03-18) Kazeem, Issa; Jafar Biazar; Babatunde Morufu Yisa
    The main idea proposed in this paper is the perturbed shifted Chebyshev Galerkin method for the solutions of delay Fredholm and Volterra integrodifferential equations. The application of the proposed method is also extended to the solutions of integro-differential difference equations. The method is validated using some selected problems from the literature. In all the problems that are considered, the new proposed approach performs better than many other methods.
