Wilhelm Sanders: According to the Guide to the Expression of Uncertainty in Measurement (GUM) and the International Vocabulary of Metrology (VIM), the uncertainty of measurement is a measure of the ...

Measurement uncertainty represents a fundamental parameter in analytical chemistry, encapsulating the range within which the true value of a measurement is expected to lie.

Understanding the elements that contribute to NF measurement uncertainty is very important. As the noise-source uncertainty may be the biggest contributor, pay special attention to it.

As a result, measurement uncertainty must be established on the balance in situ. Once a minimum weight is established, it must be monitored and controlled.

This uncertainty could play out at all scales, Korbel says. What's often interpreted as uncertainty in measurement may be uncertainty in the parameters in disguise.

Heisenberg’s uncertainty principle put an end to the dream of a perfectly knowable world. In the 1980s, physicists began to glimpse a silver lining around the cloud of quantum uncertainty. Quantum ...

Uncertainty analysis can provide a basis for making difficult decisions about reducing or redirecting sampling effort, as will be illustrated in case studies involving mercury contamination in fish ...
