Standard addition method with cumulative additions: Monte Carlo uncertainty evaluation
(Elsevier B.V., 2019-06-20)
The cumulative standard addition method allows the calibration of an instrument affected by matrix effects when a small sample volume is available. Recently, it was developed and validated a metrologically sound procedure ...
Uncertainty estimation of anions and cations measured by ion chromatography in fine urban ambient particles (PM 2.5)
(2012)
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 NO 3 -2 and SO 4 -2 in ...
Uncertainty Model For Quantitative Precipitation Estimation Using Weather Radars
This paper introduces an uncertainty model for
the quantitatively estimate precipitation using weather radars.
The model considers various key aspects associated to radar
calibration, attenuation, and the tradeoff between ...
Uncertainty on measurement of elastomeric 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 ...
Uncertainties propagation and global sensitivity analysis of the frequency response function of piezoelectric energy harvesters
(Institute of Physics, 2017)
The goal of this work is to describe a framework to propagate uncertainties in piezoelectricenergy harvesters(PEHs). These uncertainties are related to the incomplete knowledge of themodel parameters. The framework presented ...
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 measurement function is strongly non-linear the use ...
Chapter Introduction Institutional Ambiguity and the Politics of Uncertainty : A New Perspective on Refugee Governance
Lebanon hosts the highest number of refugees per capita worldwide and is central to European policies of outsourcing migration management. Hybrid Political Order and the Politics of Uncertainty is the first book to critically ...
Framework for conformity assessment based on an analogy with the Uncertainty Principle of Quantum Mechanics (FCAUP)
(2018-09-01)
This paper aims to introduce an innovative framework, named FCAUP, for planning and implementing conformity assessment based on a conceptual analogy with Heisenberg's Uncertainty Principle of Quantum Mechanics. Conformity ...
