Numerical validation of probabilistic laws to evaluate finite element error estimates

open access: yesMathematical Modelling and Analysis, 2021
We propose a numerical validation of a probabilistic approach applied to estimate the relative accuracy between two Lagrange finite elements Pk and Pm,(k < m).

Linearization errors in discrete goal-oriented error estimation

open access: yesComputer Methods in Applied Mechanics and Engineering, 2023
This paper is concerned with goal-oriented a posteriori error estimation for nonlinear functionals in the context of nonlinear variational problems solved with continuous Galerkin finite element discretizations. A two-level, or discrete, adjoint-based approach for error estimation is considered.

On improved P1-interpolation error estimates in W1,p(0, 1): application to the finite element method

open access: yesMathematical Modelling and Analysis
Based on a new Taylor-like formula, we derived an improved interpolation error estimate in W1,p. We compare it with the classical error estimates based on the standard Taylor formula, and also with the corresponding interpolation error estimate, derived

Quantum Calculus-Based Error Estimations in Hermite-Hadamard Type Inequalities [PDF]

open access: yesSahand Communications in Mathematical Analysis
The main aim of this article is to present error approximations for Hermite-Hadamard inequalities, which are connected with $_{\omega_{1}}\mathfrak{q}$-fractional calculus operators and are based on $\mathrm{(\rho, m)}$-convex functions.

Perona‐Malik equation ‐ error estimates for explicit finite volume scheme

open access: yesMathematical Modelling and Analysis, 2005
Error estimates in the L2 norm for the explicit fully discrete numerical finite volume scheme are derived and proved for Perona‐Malik equation. Numerical example is also presented.

Block-Centered Finite-Difference Methods for Time-Fractional Fourth-Order Parabolic Equations

open access: yesFractal and Fractional, 2023
The block-centered finite-difference method has many advantages, and the time-fractional fourth-order equation is widely used in physics and engineering science.

Exploring Preferences for a Digital Single‐Session Intervention for Adolescent Siblings of Youth With Cancer

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction Adolescent siblings of children with cancer are at elevated risk for psychosocial problems. Unfortunately, various barriers such as limited family time and resources, conflicting schedules, and psychosocial staffing constraints at cancer centers hinder sibling access to support.

Clinical Course and Impact of Breaks in Therapy for Children With Relapsed/Refractory Solid Tumors

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction Pediatric relapsed or refractory (R/R) solid tumors carry a dismal prognosis, and postrelapse patient experiences are not well described. We present postrelapse outcomes, including number of R/R events and subsequent therapy regimens.

Quantum solutions of a nonlinear Schrödinger equation [PDF]

open access: yesIranian Journal of Numerical Analysis and Optimization
In the present paper, we precisely conduct a quantum calculus method for the numerical solutions of PDEs. A nonlinear Schrödinger equation is considered. Instead of the known classical discretization methods based on the finite difference scheme, Adomian

Unified Convergence Analysis of Chebyshev–Halley Methods for Multiple Polynomial Zeros

open access: yesMathematics, 2022
In this paper, we establish two local convergence theorems that provide initial conditions and error estimates to guarantee the Q-convergence of an extended version of Chebyshev–Halley family of iterative methods for multiple polynomial zeros due to ...
