Determination of volumetric uncertainty for geological bodies detected by boreholes
(Elsevier B.V., 2015-04-01)
The volume of a mineralized body depends on the information available on borders between mineralization and host rocks. Sometimes, information is limited and a precise determination of the volume of ore body is not possible. ...
Uncertainty of residual stresses measurement by layer removal
(PERGAMON-ELSEVIER SCIENCE LTD, 2006)
A model to evaluate the uncertainty in the measurement of the through-thickness residual stress distribution in plates by the layer removal technique is presented. Thin layers were chemically etched from a stripe on ...
USE OF MONTE CARLO SIMULATIONS FOR THE CALCULATION OF THE UNCERTAINTY ESTIMATE IN THE ELECTROCHEMICAL DETECTION OF URIC ACID IN PLASMA SAMPLES
(Tche Quimica Group, 2018-01-01)
This work presents a low cost, simple and adequately reliable electrochemical alternative for the determination of uric acid in human serum in comparison to the enzymatic colorimetric reference method. The quality of the ...
Uncertainty analysis of positional deviations of CNC machine tools
(ELSEVIER SCIENCE INC, 2004)
The assessment of the measurement uncertainty is an indispensable task in all calibration procedures. By international accord, the evaluation is to be done in accordance with the ISO Guide to the Expression of Uncertainty ...
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 ...
Combining inconsistent data
(IEEE, 2007)
At present, the most widely used procedure for finding the value of a quantity from data obtained by different observers involves calculating the inverse-variance weighted mean of the observers' estimates. This method ...

Coverage intervals according to MARLAP, Bayesian statistics and the new ISO 11929 for ionising radiation measurements
(PERGAMON-ELSEVIER SCIENCE LTD, 2012)
The coverage intervals stipulated by ISO 11929 (2010) for estimating the uncertainty from ionising radiation measurements of replicate samples are compared with those of MARLAP (= Multi-Agency Radiological Laboratory ...
