Selection and Treatment of Data for Radiocarbon Calibration: An Update to the International Calibration (IntCal) Criteria [PDF]

, 2013
High-quality data from appropriate archives are needed for the continuing improvement of radiocarbon calibration curves. We discuss here the basic assumptions behind 14C dating that necessitate calibration and the relative strengths and weaknesses of ...

Testing of calibration models in order to certify the overall reliability of the trisonic blowdown wind tunnel of VTI [PDF]

FME Transactions, 2010
It is strongly recommended that wind tunnel calibrations become a regular part of the operational cycle for any wind tunnel. They facilitate tunnel-totunnel data comparisons. Standard calibration model, representing a generic winged missile configuration,

Assessing the Calibration of Dichotomous Outcome Models with the Calibration Belt [PDF]

The Stata Journal: Promoting communications on statistics and Stata, 2017
The calibration belt is a graphical approach designed to evaluate the goodness of fit of binary outcome models such as logistic regression models. The calibration belt examines the relationship between estimated probabilities and observed outcome rates. Significant deviations from the perfect calibration can be spotted on the graph.

A simple NWA calibration algorithm based on a transfer standard [PDF]

, 1997
A new two-port network analyzer (NWA) calibration technique is here presented. It uses a single two-port transfer standard plus a known reflectance to perform the calibration process.

Calibrating a flow model in an irrigation network: Case study in Alicante, Spain

Spanish Journal of Agricultural Research, 2017
The usefulness of models depends on their validation in a calibration process, ensuring that simulated flows and pressure values in any line are really occurring and, therefore, becoming a powerful decision tool for many aspects in the network management

Sequential calibration of material constitutive model using mixed-effects calibration

Mechanics & Industry, 2023
Identifying model parameters is nowadays intrinsically linked with quantifying the associated uncertainties. While classical methods allow to handle some types of uncertainties such as experimental noise, they are not designed to take into account the ...
