To elucidate the capability of laboratories to determine allergen contents, an international interlaboratory trial was conducted using meat products spiked with 12 allergens. The measurement uncertainty was calculated independent of the applied method simulating realistic situations when comparing analysis certificates from different laboratories. The measurement uncertainty was revealed to be ...

In instrumentation based on an analog-to-digital converter (ADC), the performance of data acquisition (DAQ) device has a direct impact on the performance index of the whole measurement system, so it has an important significance that research the uncertainty analysis of data acquisition board. This paper proposes an automatic measurement system based on DAQ board with automatic uncertainty eval...

Measurement technology has made an enormous progress in the last decade. With advent of knowledge representation, various object-oriented models for measurement systems have been developed past. Most common limitations all these were not incorporating uncertainty process. In this paper, we proposed model depicting information and flow process, including uncertainty. The three major object class...

In a recent publication [PRL 111, 160405 (2013)] we proved a version of Heisenberg’s errordisturbance tradeoff. This result was in apparent contradiction to claims by Ozawa of having refuted these ideas of Heisenberg. In a direct reaction [arXiv:1308.3540] Ozawa has called our work groundless, and has claimed to have found both a counterexample and an error in our proof. Here we answer to these...

UNLABELLED This work applied a propagation of uncertainty method to typical total suspended particulate (TSP) sampling apparatus in order to estimate the overall measurement uncertainty. The objectives of this study were to estimate the uncertainty for three TSP samplers, develop an uncertainty budget, and determine the sensitivity of the total uncertainty to environmental parameters. The sampl...

When calibrating a machine tool, multiple measurement tasks will be performed, each of which has an associated uncertainty of measurement. International Standards and best-practice guides are available to aid with estimating uncertainty of measurement for individual tasks, but there is little consideration for the temporal influence on the uncertainty when considering interrelated measurements....

Measurement uncertainty evaluation based on the Monte Carlo method (MCM) with the assumption that all uncertainty sources are independent is common. For some measure problems, however, the correlation between input quantities is of great importance and even essential. The purpose of this paper is to provide an uncertainty evaluation method based on MCM that can handle correlated cases, especial...
