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.

Error Estimates for Measurements of Cosmic Shear

open access: yes, 2002
In the very near future, weak lensing surveys will map the projected density of the universe in an unbiased way over large regions of the sky. In order to interpret the results of studies it is helpful to develop an understanding of the errors associated

Analysis for time discrete approximations of blow-up solutions of semilinear parabolic equations [PDF]

open access: yes, 2011
We prove a posteriori error estimates for time discrete approximations, for semilinear parabolic equations with solutions that might blow up in finite time. In particular we consider the backward Euler and the Crank–Nicolson methods.

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

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.

Robust error estimates in weak norms for advection dominated transport problems with rough data [PDF]

open access: yes, 2014

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.

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

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.

Preferences of Pediatric Patients and Their Caregivers for Chemotherapy‐Induced Nausea and Vomiting Control Endpoints: A Mixed Methods Study

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Purpose Although not always achieved, complete chemotherapy‐induced nausea and vomiting (CINV) control is the conventional goal of CINV prophylaxis. In this two‐center, mixed‐methods study, we sought to understand the preferences of adolescent patients and family caregivers for CINV control endpoints.
