Solving singularly perturbed fredholm integro-differential equation using exact finite difference method [PDF]

open access: yesBMC Research Notes, 2023
Objectives In this paper, a numerical scheme is designed for solving singularly perturbed Fredholm integro-differential equation. The scheme is constructed via the exact (non-standard) finite difference method to approximate the differential part and the

An efficient variable stepsize rational method for stiff, singular and singularly perturbed problems

open access: yesAlexandria Engineering Journal, 2022
In this article, a new iterative method of the rational type having fifth-order of accuracy is proposed to solve initial value problems. The method is self-starting, stable, consistent, and convergent, whereas local truncation error analysis has also ...

Dynamic analysis of delayed vaccination process along with impact of retrial queues

open access: yesComputational and Mathematical Biophysics, 2023
An unprecedented and precise time-scheduled rollout for the vaccine is needed for an effective vaccination process. This study is based on the development of a novel mathematical model considering a delay in vaccination due to the inability to book a ...

Development and nationwide implementation of a postdischarge responsive parenting intervention program for very preterm born children: The TOP program

open access: yesInfant Mental Health Journal: Infancy and Early Childhood, Volume 42, Issue 3, Page 423-437, May/June 2021., 2021
ABSTRACT A previous randomized controlled trial has suggested the effectiveness of a Dutch postdischarge responsive parenting program for very preterm (VPT) infants, indicating that nationwide implementation was justified. This paper describes the development and nationwide implementation of the intervention, known as the TOP program, which consisted ...

Adiabatic integrators for highly oscillatory second order linear differential equations with time-varying eigendecomposition [PDF]

open access: yes, 2005
. Numerical integrators for second order differential equations with time-dependent high frequencies are proposed and analysed. We derive two such methods, called the adiabatic midpoint rule and the adiabatic Magnus method. The integrators are based on a

An adaptive stepsize algorithm for the numerical solving of initial-value problems

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2015
The present paper focuses on the efficient numerical solving of initial-value problems (IVPs) using digital computers and one-step numerical methods. We start from considering that the integration stepsize is the crucial factor in determining the number ...
