Semi-Implicit Euler Schemes for Ordinary Differential Inclusions [PDF]

open access: yesSIAM Journal on Numerical Analysis, 2014
Two semi-implicit Euler schemes for differential inclusions are proposed and analyzed in depth. An error analysis shows that both semi-implicit schemes inherit favorable stability properties from the differential inclusion. Their performance is considerably better than that of the implicit Euler scheme, because instead of implicit inclusions only ...

Fractional SDEs with stochastic forcing: Existence, uniqueness, and approximation

open access: yesNonlinear Analysis, 2023
In this article, we are interested in fractional stochastic differential equations (FSDEs) with stochastic forcing, i.e., to FSDE we add a stochastic forcing term.

Implicit Euler Implementation of Twisting Controller and Super-Twisting Observer without Numerical Chattering: Precise Quasi-Static MEMS Mirrors Control

open access: yesMATEC Web of Conferences, 2019
The quasi-static operations of MEMS mirror are very sensitive to undesired oscillations due to its very low damping. It has been shown that closed-loop control can be superior to reduce those oscillations than open-loop control in the literature. For the

Hybrid method for singularly perturbed Robin type parabolic convection–diffusion problems on Shishkin mesh

open access: yesPartial Differential Equations in Applied Mathematics, 2023
This work presents a numerical solution to singularly perturbed Robin-type parabolic convection–diffusion problems. A hybrid method that combines the central difference scheme in the inner region and the midpoint of the upwind scheme in the outer region ...

Bubble-enhanced quadrilateral finite element formulation for nonlinear analysis of geotechnical problems

open access: yesUnderground Space, 2018
We investigate a new numerical procedure based on a bubble-enriched finite element formulation in combination with the implicit backward Euler scheme for nonlinear analysis of strip footings and stability of slopes.

The spectral implementation of the nonstationary Stokes problem with nonstandard boundary conditions

open access: yesBoundary Value Problems, 2020
This paper deals with the implementation of the spectral discretization of the vorticity–velocity–pressure formulation of the nonstationary Stokes problem. We use the implicit Euler scheme for the discretization in time.

Spectral Galerkin Method in Space and Time for the 2D g-Navier-Stokes Equations

open access: yesAbstract and Applied Analysis, 2013
We prove the H2-stability and L2-error analysis of the spectral Galerkin method in space and time with the implicit/explicit Euler scheme for the 2D g-Navier-Stokes equations in bounded domains when the initial data belong to H1.

Finite difference approximations for a class of non-local parabolic equations

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1997
In this paper we study finite difference procedures for a class of parabolic equations with non-local boundary condition. The semi-implicit and fully implicit backward Euler schemes are studied.
