A computer program for a general case evaluation of the expanded uncertainty

Accreditation and Quality Assurance, 2003
The ISO Guide to the Expression of Uncertainty in Measurement provides a uniform method for the evaluation of combined standard uncertainty of a measurand whose expectation and standard deviation are stable over the measurement period. However, the method provided for the evaluation of the expanded uncertainty is not complete. Particularly, it does not

The use of a Monte Carlo method for evaluating uncertainty and expanded uncertainty

Metrologia, 2006
The Guide to the Expression of Uncertainty in Measurement (GUM) is the internationally accepted master document for the evaluation of uncertainty. It contains a procedure that is suitable for many, but not all, uncertainty evaluation problems met in practice.

Expanded Uncertainty of a Measurement and an Uncertainty Budget for a Single Measurement

2014
This chapter takes the standard uncertainty calculated in the previous chapter and shows how to apply a statistical confidence in order to determine the expanded uncertainty, which is commonly referred to as “the uncertainty of a measurement.” The chapter demonstrates how uncertainties quoted at one level of confidence (e.g., on a calibration ...

Expandability, reversibility and harvesting under uncertainty

Fisheries Research, 1999
Abstract Uncertain stock evolution can render harvest output adjustment costly. However, the fleet can anticipate future stock disturbance and alter its current harvest output to avoid costly future adjustment. It can lower its current output and create flexibility to expand future harvest, making current harvest behaviour more conservative; whilst ...

Expanded uncertainty regions for complex quantities

Metrologia, 2013
The expanded measurement uncertainty of a complex quantity is a region in the complex plane surrounding the measured value. This paper considers different shaped uncertainty regions in the form of ellipses, circles, rectangles and parallelograms. The different types of region are compared, under a variety of measurement error conditions, with regard to

The Expanded Uncertainty for Radio Frequency Immunity Testing

PIERS Online, 2010
This paper is concerned with the problems of electromagnetic compatibility for RF (Radio Frequency) immunity testing according to the EN 61000-4-3 standard. The measurement uncertainty budget calculation techniques recommended in standardizing documents are barely described and very often they are not adapted to the specific needs of tests performed ...

Evaluating expanded uncertainty in measurement with a fitted distribution

Metrologia, 2008
It is recommended in the internationally adopted standard GUM that the measurement result of a measurand Y, determined from input quantities through a known functional relationship, should be reported as an uncertainty interval with a specific level of confidence.

Improved estimates of expanded measurement uncertainty

Analytical Methods
An improved estimate of expanded measurement uncertainty, when this is calculated using ANOVA results from a nested experimental design, is described. In cases where the number of sampling targets is ≪30, more accurate coverage factors are calculated.

Moments and maximum entropy method for expanded uncertainty estimation in measurements

2017 IEEE International Instrumentation and Measurement Technology Conference (I2MTC), 2017
The normal approximation and Monte Carlo simulation methods are widely used in the metrology to evaluate the expanded uncertainty, whereby the latter method is known to be the most robust and reliable. In some cases, however, (e.g., when the probability distribution is not known a priori) different frameworks may be desired as an alternative to the ...

Control of the tandem hot strip mill under expanded uncertainties and disturbances

2013 IEEE Industry Applications Society Annual Meeting, 2013
Previously, it has been shown that a controller based on the use of the state-dependent-Riccati-equation technique has resulted in significant improvements in performance. In our previous work, controller performance under certain disturbances and uncertainties that are considered typical for tandem hot rolling was addressed.
