GUM, the internationally approved technique for calculating measurement uncertainty, is reliant on the availability of a certified reference sample. Likewise, to find any repeatable offset (systematic ...

How does Thermo Fisher Scientific's analytical software support the calculation of measurement uncertainty? Wilhelm Sanders: According to DIN EN ISO 17025, it is necessary to calculate the measurement ...

In a stunning leap for quantum optics, scientists have generated ultrafast light pulses whose quantum uncertainty can be ...

Performing a measurement uncertainty calculation is often seen as problematic. One of the barriers to be overcome in the wider application of measurement uncertainty (MU) to reportable values is the ...

This two-day course gives an introduction to the theory and practice of calculating Uncertainty of Measurement for chemical analysis of foods. The approach to Uncertainty measurement will follow the ...

Precision can be defined as the closeness in agreement of results during a series of repeat measurements under presumed identical conditions. These results are often expressed as a standard deviation.

For almost a century, Heisenberg's uncertainty principle has stood as one of the defining ideas of quantum physics: a ...

In the test and measurement industry, two distinct camps exist: those who favor vector network analyzers (VNA) and those who favor time domain reflectometers (TDR). Each camp relies heavily upon its ...

With today�s applications requiring lower and lower noise-figure amplifiers, noise-source uncertainty becomes a bigger and bigger concern. Microwave modeling ...

WINTERTHUR, SWITZERLAND—The Kistler Group—a global provider of dynamic measurement technoogy— announces the launch of KiXact. This is the first technology that enables measurement uncertainty to be ...

In the first round of testing, involving 60 measurements (six samples x five repeat tests x two rounds), an initial review of the results indicated that one sample consistently performed better than ...
