Application of moving kriging interpolation based on the meshless local Petrov-Galerkin (MK-MLPG) method for the two-dimensional time-dependent Schrodinger equation [PDF]
Journal of Mahani Mathematical Research, 2018 In this article, an efficient numerical technique for solving the two-dimensional time-dependent Schrodinger equation is presented. At first, we employ the meshlesslocal Petrov-Galerkin (MLPG) method based on a local weak formulation to ...

Adaptive Numerical Method for Approximation of Traffic Flow Equations
Journal of Advanced Transportation, Volume 2022, Issue 1, 2022., 2022 For a long time now, traffic equations have been considered, and different modeling has been done for it. In this article, we work on the macroscopic model, especially the most famous light model. Because these models are among the stiff and shocking problems, theoretical methods do not give good answers to these problems.

Exponentially Fitted Element‐Free Galerkin Approach for Nonlinear Singularly Perturbed Problems
Journal of Mathematics, Volume 2021, Issue 1, 2021., 2021 As it is well recognized that conventional numerical schemes are inefficient in approximating the solutions of the singularly perturbed problems (SPP) in the boundary layer region, in the present work, an effort has been made to propose a robust and efficient numerical approach known as element‐free Galerkin (EFG) technique to capture these solutions ...

Advances in Civil Engineering, Volume 2021, Issue 1, 2021., 2021 In this article, a new sinusoidal shear deformation theory was developed for static bending analysis of functionally graded plates resting on elastic foundations. The proposed theory used an undefined integral term to reduce the number of the unknown to four without any shear correction factors.
