imprecision.
Besides
imprecision and bias, possible potential sources of uncertainty are observed, including different concentrations of calibrators and reagent in different lots, multiple technologists' involvement and environmental conditions such as humidity and temperature fluctuations.
Performance of previous model-based control techniques significantly deteriorates under
imprecisions due to controller software implementation.
We created a band of error-transformed values by adding or subtracting the allowable
imprecision to the upper and lower ends of the bias-transformed values and using the most extreme values.
The combined, inherent
imprecision of both instruments was calculated as previously described.
But forget eliminating
imprecision, van Deemter contends.
As examples of the
imprecision in the field today he explores "fascist" elements in Marcus Garvey's Universal Negro Improvement Association (UNIA) and Elijah Muhammad's Lost-Found Nation of Islam.
The IG method also ensures high reproducibility, which removes the
imprecision that comes with particle analysis in the single nano range.
Burgin, whose field or position is not revealed, claims that neoclassical analysis aims at representing uncertainties and
imprecision, extends the scope of the classical calculus and analysis, and is more precise with respect to real life applications.
Figure 2 shows that the pipettes also performed consistently at Rialto Beach, with all but one of the pipettes recording
imprecision results (CV) very close to the pipette specification.
