Measurement Uncertainties in Wear Rates
Measurement uncertainties are vital to discussions of differences in measured values, yet they scarcely accompany discussions of wear and wear rates in the tribology literature. In this methods article, approaches to calculate uncertainties in single-point and steady-state wear rates are presented. The analysis includes analytical treatments of uncertainties for typical macroscopic tribology in...
متن کاملColor Measurement
One of the key elements in successfully utilizing a textile color matching and quality control system is the accurate and repeatable measurement of the samples being evaluated. Poor technique in sample measurement will greatly diminish the accuracy of the formulas produced by the shade matching software and will provide misleading results from the quality control software. Mistakes in either ar...

متن کاملAttenuation measurement uncertainties caused by speckle statistics.
Attenuation measurements can be derived from the decay of backscattered signal with depth in an inhomogeneous material. In cases such as liver tissue, where many small inhomogeneities are likely to be included in sample volumes defined by pulse and beam widths, Rayleigh statistics describe the random nature of the magnitude of backscattered pressure. The statistics of speckle underlie the uncer...
متن کاملMeasurement Uncertainties in Speaker Recognition Evaluation
The National Institute of Standards and Technology (NIST) Speaker Recognition Evaluations (SRE) are an ongoing series of projects conducted by NIST. In the NIST SRE, speaker detection performance is measured using a detection cost function, which is defined as a weighted sum of probabilities of type I error and type II error. The sampling variability results in measurement uncertainties of the ...
