The evaluation of standard uncertainty in the presence of limited resolution of indicating devices
Abstract
Since the type A evaluation of standard uncertainty according to the rules given in the ISO Guide to the Expression of Uncertainty in Measurement does not take into account the uncertainty that arises from the limited resolution of indicating devices, we show in this design note that the treatment of this problem calls for a quantity about which no statistical information is available; therefore, its uncertainty has to be derived from a type B evaluation.

Measurement errors in the optical constants obtained from THz-TDS have not been systematically analyzed.
“Nevertheless, measurement errors in the optical constants, so far, have not been systematically analyzed.”

Previous literature on uncertainty models for optical constants in THz-TDS considers only signal noise and/or does not extend the model into the time domain, and developed linear models are rarely verified by nonlinear numerical simulation.
“In those cases the work only considers the influence of signal noise and/or does not extend the model into the time domain. Furthermore, the developed linear models are rarely verified by a nonlinear numerical simulation.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
