Method for calculating the resistance of an asynchronous squirrel cage motor according to passport data and estimation of its error

open access: yesВестник Самарского государственного технического университета. Серия: Технические науки, 2021
A simpler method is proposed for determining the resistances of an induction motor (total inductive resistance, active resistance of the stator and reduced active resistance of the rotor) according to reference data.

Stability estimate and regularization for a radially symmetric inverse heat conduction problem

open access: yesBoundary Value Problems, 2017
This paper investigates a radially symmetric inverse heat conduction problem, which determines the internal surface temperature distribution of the hollow sphere from measured data at the fixed location inside it. This is an inverse and ill-posed problem.

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

Video Sensing of Nearshore Bathymetry Evolution with Error Estimate

open access: yesJournal of Marine Science and Engineering, 2019
Although coastal morphology results essentially from underwater sediment transports, the evolution of underwater beach profiles along the diverse coastlines of the world is still poorly documented.

Muon capture on deuteron using local chiral potentials

open access: yesFrontiers in Physics, 2023
The muon capture reaction μ− + d → n + n + νμ in the doublet hyperfine state is studied using nuclear potentials and consistent currents derived in the chiral effective field theory, which are local and expressed in coordinate space (the so-called ...

Standard Error of Empirical Bayes Estimate in NONMEM® VI. [PDF]

open access: yes, 2012
The pharmacokinetics/pharmacodynamics analysis software NONMEM® output provides model parameter estimates and associated standard errors. However, the standard error of empirical Bayes estimates of inter-subject variability is not available. A simple and

Optimal Convergence Analysis of Two-Level Nonconforming Finite Element Iterative Methods for 2D/3D MHD Equations

open access: yesEntropy, 2022
Several two-level iterative methods based on nonconforming finite element methods are applied for solving numerically the 2D/3D stationary incompressible MHD equations under different uniqueness conditions.

On the rate of convergence in periodic homogenization of scalar first-order ordinary differential equations [PDF]

open access: yes, 2009
In this paper, we study the rate of convergence in periodic homogenization of scalar ordinary differential equations. We provide a quantitative error estimate between the solutions of a first-order ordinary differential equation with rapidly oscillating ...
