Journal of Geophysical Research: Planets, Volume 128, Issue 4, April 2023., 2023 Abstract Seismic activity generated by impacts depends on impact conditions and properties of the impact site. Here, we combined mapping of the regolith thickness with numerical impact simulations to better estimate the seismic efficiency and seismic moment generated in small impact events in the uppermost crust on Mars.

Mathematical Methods in the Applied Sciences, Volume 46, Issue 2, Page 2117-2132, 30 January 2023., 2023 We construct an efficient hybrid numerical method for solving coupled systems of singularly perturbed linear parabolic problems of reaction‐diffusion type. The discretization of the coupled system is based on the use of an additive or splitting scheme on a uniform mesh in time and a hybrid scheme on a layer‐adapted mesh in space.

International Journal of Intelligent Systems, Volume 2023, Issue 1, 2023., 2023 The proposed research utilizes a computational approach to attain a numerical solution for the singularly perturbed delay differential equation (SPDDE) problem arising in the neuronal variability model through artificial neural networks (ANNs) with different solvers. The log‐sigmoid function is used to construct the fitness function. The implementation

A note on a generalized Shishkin-type mesh
Novi Sad Journal of Mathematics, 2018 Summary: The one-dimensional linear singularly perturbed convection-diffusion problem is discretized using the upwind scheme on a mesh which is a mild generalization of Shishkin-type meshes. The generalized mesh uses the transition point of the Shishkin mesh, but it does not require any structure of its fine and course parts. Convergence uniform in the
