Digital representation of measurement uncertainty
Measurement: Sensors, 2021 Successful digital transformation of measurement quality infrastructures must capture and share information about the metrological traceability of measurement results. So appropriate representations of measurement uncertainty, which is the cornerstone of

Point-plane distance as model for uncertainty evaluation of coordinate measurement [PDF]
Metrology and Measurement Systems, 2021 The paper presents a detailed theoretical background for coordinate measurement uncertainty evaluation by means of Type B evaluation method, taking into account information on accuracy of a coordinate measuring system given with the formula for maximum ...

Measurement uncertainty relations [PDF]
Journal of Mathematical Physics, 2014 Measurement uncertainty relations are quantitative bounds on the errors in an approximate joint measurement of two observables. They can be seen as a generalization of the error/disturbance tradeoff first discussed heuristically by Heisenberg. Here we prove such relations for the case of two canonically conjugate observables like position and momentum,

Zero‐Sequence current measurement uncertainty in three‐phase power systems during normal operation
IET Generation, Transmission & Distribution, 2021 Zero‐sequence currents in high‐voltage power systems during normal operation can have a significant influence on nearby infrastructure. It is therefore necessary to gain insight into typical levels of zero‐sequence currents in a variety of operational ...

Pruning and measures of uncertainty [PDF]
RAIRO. Informatique théorique, 1978 We introduce a new property, pruning, for measures of uncertainty and investigate its consequences. In particular, we derive a new characterization of the additive, subadditive and symmetric entropies without assuming expansibility. Pruning also provides a new motivation for Hartley's entropy.

Approaches to evaluating measurement uncertainty [PDF]
International Journal of Metrology and Quality Engineering, 2012 The Guide to the expression of measurement uncertainty, (GUM, JCGM 100) and its Supplement 1: propagation of distributions by a Monte Carlo method, (GUMS1, JCGM 101) are two of the most widely used documents concerning ...

Uncertainty in Measurement [PDF]
, 2020 Measurements of physical quantities are the corner stone upon which we humans have built the scientific perception of the world. Measurements are the distinctive means to tell the scientific truth apart from any other approach to knowledge. The fundamental concepts of measurement and uncertainty in measurement have been analysed with reference to ...

Evaluation of Measurement Uncertainty Based on Monte Carlo Method
MATEC Web of Conferences, 2018 The developments of scientific technology are inseparable from various measurement methods. Measurement uncertainty is an indication that evaluates the credibility of the measurement results directly, and it affects the development of technology and ...
