Uncertainty of measurement

The rest of the paper is organized as follows: In the next section, we recall the concept of picture fuzzy set and several operators of two picture fuzzy sets. We then propose a new MCDM method using the dissimilarity measure of picture fuzzy sets. Finally, we apply the proposed method for evaluating water reuse applications.

This thesis presents the design of a test asset system capable of testing GNSS receivers for speed accuracy and the Uncertainty of Measurements (UOM) analysis for this system. The test asset system utilises a variety of engineering solutions and is capable of maintaining high accuracy benchmarks in speed measurements. The test asset system has an UOM equal 0.4 km/h for the entire range of speeds used for GNSS speed testing. The system was designed, assembled and tested to ensure the system maintains its integrity and capability to test GNSS receivers for speed measurement.

A template for estimating uncertainties (unc.) of measured neutron-induced fission, (n,f), cross-sections (cs) is presented. This preliminary template not only lists all expected unc. sources but also supplies ranges of unc., estimates for correlations between unc. of the same and different experiments which can be used if the information is nonexistent.

In this article, we will first discuss the issues of the prompt g-ray spectroscopy regarding the control of all the uncertainties involved in the (n,n0g) cross section estimation. Secondly, we will focus on the role of theoretical modeling which, in certain cases, is crucial to reach the objectives of a few percent uncertainty on the (n,n0) cross sections.

External quality assessment schemes are evaluated by method-dependent consensus values or by method independent target values, determined with reference measurement procedures. The reference measurement procedures yield values having a high trueness and precision with a defined uncertainty of measure-ment. The great advantage of the reference measurement proce-dure is that the comparability of results in the different medical laboratories is promoted and improved intending in the same ref-erence interval for an analyte in all laboratories. ...

IMAGE SAMPLING AND RECONSTRUCTION In digital image processing systems, one usually deals with arrays of numbers obtained by spatially sampling points of a physical image. After processing, another array of numbers is produced, and these numbers are then used to reconstruct a continuous image for viewing. Image samples nominally represent some physical measurements of a continuous image field, for example, measurements of the image intensity or photographic density. Measurement uncertainties exist in any physical measurement apparatus....
