Mesh-Free MLS-Based Error-Recovery Technique for Finite Element Incompressible Elastic Computations

open access: yesApplied Sciences, 2023
The finite element error and adaptive analysis are implemented in finite element procedures to increase the reliability of numerical analyses. In this paper, the mesh-free error-recovery technique based on moving least squares (MLS) interpolation is ...

Global error estimation of linear multistep methods through the Runge-Kutta methods [PDF]

open access: yesIranian Journal of Numerical Analysis and Optimization, 2016
In this paper, we study the global truncation error of the linear multistep methods (LMM) in terms of local truncation error of the corresponding Runge-Kutta schemes. The key idea is the representation of LMM with a corresponding Runge-Kutta method.

An efficient Legendre-Galerkin approximation for the fourth-order equation with singular potential and SSP boundary condition

open access: yesOpen Mathematics, 2023
In this article, we develop an efficient Legendre-Galerkin approximation based on a reduced-dimension scheme for the fourth-order equation with singular potential and simply supported plate (SSP) boundary conditions in a circular domain. First, we deduce

Can I Trust This Location Estimate? Reproducibly Benchmarking the Methods of Dynamic Accuracy Estimation of Localization

open access: yesSensors, 2022
Despite the great attention that the research community has paid to the creation of novel indoor positioning methods, a rather limited volume of works has focused on the confidence that Indoor Positioning Systems (IPS) assign to the position estimates ...

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.

Constrained Phase Noise Estimation in OFDM Using Scattered Pilots Without Decision Feedback [PDF]

open access: yes, 2016
In this paper, we consider an OFDM radio link corrupted by oscillator phase noise in the receiver, namely the problem of estimating and compensating for the impairment.

Soft output bit error rate estimation for WCDMA [PDF]

open access: yes, 2003
This paper introduces a method that computes an estimation of the bit error rate (BER) based on the RAKE receiver soft output only. For this method no knowledge is needed about the channel characteristics nor the precise external conditions.

Adaptive resizing-based multi-resolution particle method

open access: yesMechanical Engineering Journal, 2021
Multi-resolution techniques are essential for the performance of large-scale simulations of computational fluid dynamics with particle methods. In this study, a novel adaptive multi-resolution scheme has been developed for the least squares moving ...

Errors on errors – Estimating cosmological parameter covariance [PDF]

open access: yesProceedings of the International Astronomical Union, 2014
AbstractCurrent and forthcoming cosmological data analyses share the challenge of huge datasets alongside increasingly tight requirements on the precision and accuracy of extracted cosmological parameters. The community is becoming increasingly aware that these requirements not only apply to the central values of parameters but, equally important, also
