Robust Radio Interferometric Calibration Using the t-Distribution [PDF]

open access: yes, 2013
A major stage of radio interferometric data processing is calibration or the estimation of systematic errors in the data and the correction for such errors.

Computer model calibration with large non-stationary spatial outputs: application to the calibration of a climate model [PDF]

open access: yes, 2018
Bayesian calibration of computer models tunes unknown input parameters by comparing outputs with observations. For model outputs that are distributed over space, this becomes computationally expensive because of the output size.

The accuracy of NIRS in predicting chemical composition and fibre digestibility of hay-based total mixed rations

open access: yesItalian Journal of Animal Science, 2021
The aim of this study was to develop near-infrared spectroscopy (NIRS) prediction models for the estimation of chemical components and the fibre undegradable fractions (uNDF) of hay-based total mixed rations (TMR).

Frequency-domain gravitational waves from non-precessing black-hole binaries. II. A phenomenological model for the advanced detector era [PDF]

open access: yes, 2015
We present a new frequency-domain phenomenological model of the gravitational-wave signal from the inspiral, merger and ringdown of non-precessing (aligned-spin) black-hole binaries.

Sensor Modeling and Calibration Method Based on Extinction Ratio Error for Camera-Based Polarization Navigation Sensor

open access: yesSensors, 2020
The performance of camera-based polarization sensors largely depends on the estimated model parameters obtained through calibration. Limited by manufacturing processes, the low extinction ratio and inconsistency of the polarizer can reduce the ...

Financial model calibration using consistency hints [PDF]

open access: yes, 2001
We introduce a technique for forcing the calibration of a financial model to produce valid parameters. The technique is based on learning from hints. It converts simple curve fitting into genuine calibration, where broad conclusions can be inferred from ...

An Empirical Atmospheric Density Calibration Model Based on Long Short-Term Memory Neural Network

open access: yesAtmosphere, 2021
The accuracy of the atmospheric mass density is one of the most important factors affecting the orbital precision of spacecraft at low Earth orbits (LEO). Although there are a number of empirical density models available to use in the orbit determination

Copula Calibration [PDF]

open access: yes, 2013
We propose notions of calibration for probabilistic forecasts of general multivariate quantities. Probabilistic copula calibration is a natural analogue of probabilistic calibration in the univariate setting.

Efficient methods of automatic calibration for rainfall-runoff modelling in the Floreon+ system [PDF]

open access: yes, 2017
Calibration of rainfall-runoff model parameters is an inseparable part of hydrological simulations. To achieve more accurate results of these simulations, it is necessary to implement an efficient calibration method that provides sufficient refinement of

Correction of bias in self-reported sitting time among office workers – a study based on compositional data analysis

open access: yesScandinavian Journal of Work, Environment & Health, 2020
OBJECTIVE: Emerging evidence suggests that excessive sitting has negative health effects. However, this evidence largely relies on research using self-reported sitting time, which is known to be biased.
