Nonstandard abbreviations: BV, biological variation; S100B, S100-[beta] protein; NSE, neuron-specific enolase; [CV.sub.I], within-person BV; RCV, reference change value; [CV.sub.G], between-person BV; [CV.sub.A], analytical 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.
