uncertainty in calibration
1Calibration — is the process of establishing the relationship between a measuring device and the units of measure. This is done by comparing a device or the output of an instrument to a standard having known measurement characteristics. For example the length… …
2Measurement uncertainty — In metrology, measurement uncertainty is a non negative parameter characterizing the dispersion of the values attributed to a measured quantity. The uncertainty has a probabilistic basis and reflects incomplete knowledge of the quantity. All… …
3Measurement microphone calibration — In order to take a scientific measurement with a microphone, its precise sensitivity must be known (in volts per Pascal). Since this may change over the lifetime of the device, it is necessary to regularly calibrate measurement microphones. This… …
4National Accreditation Board for Testing and Calibration Laboratories — (NABL), is an autonomous body under the aegis of Department of Science Technology, Government of India, and is registered under the Societies Act. Contents 1 About NABL 2 Objectives 3 Laboratory Accreditation …
5GLUE (uncertainty assessment) — In hydrology, GLUE or Generalized Likelihood Uncertainty Estimation is a method to quantify the uncertainty of model predictions. The method has been introduced by Beven and Binley (1992). The basic idea of GLUE is that given our inability to… …
6Radiocarbon dating — (sometimes simply known as carbon dating) is a radiometric dating method that uses the naturally occurring radioisotope carbon 14 (14C) to estimate the age of carbon bearing materials up to about 58,000 to 62,000 years.[1] Raw, i.e. uncalibrated …
7Metrology — This article is about the science of measurement. For the study of weather see Meteorology. A scientist stands in front of a microarcsecond (1 millionth of 1 arcsecond or 1 millionth of 1/3600 degree) testbed. Metrology is the science of… …
8Kilogram — Kg redirects here. For other uses, see Kg (disambiguation). Kilogram A computer generated image of the international prototype kilogram (IPK). The IPK is the kilogram. The IPK, which is roughly the size of a golf ball, sits here alongside a ruler …
9Cosmic distance ladder — * Light green boxes: Technique applicable to star forming galaxies. * Light blue boxes: Technique applicable to Population II galaxies. * Light Purple boxes: Geometric distance technique. * Light Red box: The planetary nebula luminosity function… …
10Scattering parameters — or S parameters are properties used in electrical engineering, electronics engineering, and communication systems engineering describing the electrical behavior of linear electrical networks when undergoing various steady state stimuli by small… …
