When measuring the tooth flank of hypoid gear, the measurement datum surface (the large end surface of the gear) does not always coincide with the design bases (the theoretical mounting distance), and this non-coincidence error would affect the tooth flank measurement results.
The Table 7 also shows observed/predicted wind coincidences, errors in vorticity and angle errors in wind directions.
I grew up reading 19th-century novels and late Victorian children's books, so I try for a good story full of coincidence and error, landscape and weather.
One plane contains 12 plastic scintillators arranged in the x and y coordinates and has 144 coincidence elements; its RMS error of point resolution is ΔX = ±2.0 cm, ΔY = ±2.0 cm (Fig. 2).
Different apparatuses have different backgrounds and systematic errors, making the coincidence, if it is an artifact, most unlikely.
One common thinking error related to coincidences is known in psychology as Type 1 error.
If the predicted mean wave coincides with the synthetic mean wave within the error range, we regard their coincidence as significant.
Table 3 shows the consequences of calibration errors between scanner and coincidence counter.
These included an admitted programming error that generated spurious coincidences between Weber's two detectors, possible selection bias by Weber, Weber's report of coincidences between two detectors when the data had been taken four hours apart, and whether or not Weber's experimental apparatus could produce the narrow coincidences claimed.
Ventilation heterogeneity is expected to increase errors related to spatial coincidence between techniques and may have jeopardized the results in the present study.
