Selection of microphone location, measurement uncertainty and calculated noise maps
(International Institute of Acoustics and Vibration, IIAV, 2017)
Uncertainty analysis of a laser calibration system for evaluating the positioning accuracy of a numerically controlled axis of coordinate measuring machines and machine tools
(2008)
This paper presents an uncertainty analysis of a Positional Error Calibrator based on a laser interferometer system. This laser calibration system is capable of evaluating the positioning accuracy of a numerically controlled ...
Generalized expressions of second and third order for the evaluation of standard measurement uncertainty
(2011)
The Guide to the Expression of Uncertainty in Measurement (GUM) requires the use of a
first-order Taylor series expansion for propagating uncertainties. However, when the mea-surement function is strongly non-linear the ...
Uncertainty estimation of anions and cations measured by ion chromatography in fine urban ambient particles (PM2.5)
(Springer, 2011-11-19)
The present work presents a measurement
uncertainty evaluation according to Guide to the Expression
of Uncertainty in Measurement (GUM) of the
concentration of the cations K? and Li? and anions NO3
-2
and SO4
-2 in ...
Analysis of Key Comparisons Incorporating Knowledge About Bias
(2012)
A method is proposed for analyzing key comparison data. It is based on the assumption that each laboratory participating in the comparison exercise obtains independent and consistent estimates of the measurand and that, ...

Uncertainty on measurement of elastomemeric isolators effective properties
(2021)
Elastomeric isolators are subjected to a series of non-destructive tests with several repeated deformation cycles. For each cycle, effective properties are calculated and afterward averaged. Despite their variability, and ...
Metodologia de cálculo de incertezas de medição para uma bancada dinamométrica para motores de combustão interna
(Universidade Federal de Santa MariaBrasilUFSMCentro de Tecnologia, 2023-02-16)
Measurement uncertainties are related to experiments and measurement instruments. They quantify the reliability of the experiment, that is, the greater the uncertainty, the lower the reliability of the result. According ...
