In contrast, the main goals of the D study are to deduce or explain the measurement results according to the specific decision needs, reconstruct a variety of generalized regions, estimate the size of the variance components at the level of the sample mean, and then estimate the various measurement errors and measurement accuracy indices (relative error and GC or absolute error and DI) to provide valuable information that can be used to improve measures (Yang & Zhang, 2003).

The absolute error between measured flow [V.sub.U], which was measured by the ultrasonic meter, and the calculated flow [V.sub.C], which was calculated using the corrected valve command, was taken for the first set of errors [Error.sub.1].
Now, we will use the bound in (3.10) to estimate the absolute error |[[lambda]*.sub.l] - [[lambda].sub.l,N]| when [[lambda]*.sub.l] is the exact eigenvalue of the problem (1.5)-(1.6) and [[lambda].sub.l,N] is the zero of the function [[DELTA].sub.l,N]([lambda]).
