Cubic spline solutions of the ninth order linear and non-linear boundary value problems

open access: yesAlexandria Engineering Journal, 2022
A lot of numerical formulations of physical phenomena contain 9th-order BVPs. The presented probe intends to consider the spline solutions of the 9th-order boundary value problems using Cubic B Spline(CBS).

Solutions of BVPs arising in hydrodynamic and magnetohydro-dynamic stability theory using polynomial and non-polynomial splines

open access: yesAlexandria Engineering Journal, 2021
This paper describes the exceptionally precise results of 6th-order and 8th-order nonlinear boundary-value problems(BVPs). Cubic-Nonpolynomial spline(CNPS) and Cubic-polynomial spline(CNPS) are utilized to solve such types of BVPs.

Enhancing parental reflective functioning through early dyadic interventions: A systematic review and meta‐analysis

open access: yesInfant Mental Health Journal: Infancy and Early Childhood, Volume 42, Issue 1, Page 21-34, January/February 2021., 2021
ABSTRACT Parental reflective functioning (PRF) is an important predictor of infant attachment, and interventions that target parent–infant/toddler dyads who are experiencing significant problems have the potential to improve PRF. A range of dyadic interventions have been developed over the past two decades, some of which explicitly target PRF as part ...

Modeling of curves by a design-control approximating refinement scheme

open access: yesArab Journal of Basic and Applied Sciences, 2023
This paper introduces a modified method for construction of a new design-control 6-point approximating refinement scheme. The construction of the new scheme is based on translation of the points of 4-point approximating refinement scheme to the new ...

Deficient quartic spline of Marsden type with minimal deviation by the data polygon [PDF]

open access: yes, 2023
In this work we construct the deficient quartic spline with the knots following the Marsden’s scheme and prove the existence and uniqueness of the deficient quartic spline with minimal deviation by the data polygon.

Nonparametric relative recursive regression

open access: yesDependence Modeling, 2020
In this paper, we propose the problem of estimating a regression function recursively based on the minimization of the Mean Squared Relative Error (MSRE), where outlier data are present and the response variable of the model is positive.

Some familys of Bézier curves [PDF]

open access: yesComputer Methods in Materials Science, 2006
In this paper some interesting families of Bézier curves are constructed. In particular, these curves can be used to uniform approximation of polygons or saw-tooth functions.

Ball convergence for combined three-step methods under generalized conditions in Banach space [PDF]

open access: yes, 2020
We give a local convergence analysis for an eighth-order convergent method in order to approximate a locally unique solution of nonlinear equation for Banach space valued operators. In contrast to the earlier studies using hypotheses up to the seventh Fr´
