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

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.

Impulsive Linearly Implicit Euler Method for the SIR Epidemic Model with Pulse Vaccination Strategy

open access: yesAxioms
In this paper, a new numerical scheme, which we call the impulsive linearly implicit Euler method, for the SIR epidemic model with pulse vaccination strategy is constructed based on the linearly implicit Euler method. The sufficient conditions for global

Convergence of an implicit Euler Galerkin scheme for Poisson–Maxwell–Stefan systems [PDF]

open access: yesAdvances in Computational Mathematics, 2019
A fully discrete Galerkin scheme for a thermodynamically consistent transient Max-well-Stefan system for the mass particle densities, coupled to the Poisson equation for the electric potential, is investigated. The system models the diffusive dynamics of an isothermal ionized fluid mixture with vanishing barycentric velocity.
