A Posteriori Estimation of Dimension Reduction Errors [PDF]

open access: yes, 2004
A new a posteriori error estimator is presented for the verification of the dimensionally reduced models stemming from the elliptic problems on thin domains. The original problem is considered in a general setting, without any specific assumptions on the domain geometry, coefficients and the right-hand sides.

A posteriori error estimator and error control for contact problems [PDF]

open access: yesMathematics of Computation, 2009
In this paper, we consider two error estimators for one-body contact problems. The first error estimator is defined in terms of H ( div

Goal Oriented Time Adaptivity Using Local Error Estimates

open access: yesAlgorithms, 2020
We consider initial value problems (IVPs) where we are interested in a quantity of interest (QoI) that is the integral in time of a functional of the solution. For these, we analyze goal oriented time adaptive methods that use only local error estimates.

A Posteriori Error Estimates for Pressure-Correction Schemes [PDF]

open access: yesSIAM Journal on Numerical Analysis, 2016
Summary: A posteriori error estimates for time discretization of the incompressible Stokes equations by pressure-correction methods are presented. We rigorously prove global upper bounds for the incremental backward Euler scheme as well as for the two-step backward differential formula method (BDF2) in rotational form.

Application of Mixed Kalman Filter to Passive Radar Target Tracking

open access: yesLeida xuebao, 2015
To improve the estimation accuracy of the error covariance matrix in Unscented Kalman Filter (UKF). With the passive radar target tracking model, a novel Mixed Kalman Filter (MKF) is proposed, Firstly, the UKF is used to conduct a posteriori estimate for

On the Wavelet Collocation Method for Solving Fractional Fredholm Integro-Differential Equations

open access: yesMathematics, 2022
An efficient algorithm is proposed to find an approximate solution via the wavelet collocation method for the fractional Fredholm integro-differential equations (FFIDEs).

A Posteriori Error Estimates for Domain Decomposition Methods

open access: yes, 2023
Nowadays, a posteriori error control methods have formed a new important part of the numerical analysis. Their purpose is to obtain computable error estimates in various norms and error indicators that show distributions of global and local errors of a particular numerical solution.

The Modified Trapezoidal Rule for Computing Hypersingular Integral on Interval

open access: yesJournal of Applied Mathematics, 2013
The modified trapezoidal rule for the computation of hypersingular integrals in boundary element methods is discussed. When the special function of the error functional equals zero, the convergence rate is one order higher than the general case.
