Gear Health Threshold Setting Based On a Probability of False Alarm
There is no established threshold or limit for gear vibration based condition indicators (CI) that indicates when a gear is in need of maintenance. The best we can do is set CI thresholds statistically, based on some small probability of false alarm. Further, to the best of our knowledge, there is no single CI that is sensitive to every failure mode of a gear. This suggests that any condition b...
متن کاملProbability of false alarm estimation in oversampled active sonar systems
The probability of false alarm (Pfa) in active sonar systems is an important system performance measure. This measure is typically estimated by the proportion of alarms to opportunities over some finite window, essentially forming the sample exceedance distribution function (EDF). It is common for sonar systems to be ‘over-sampled’; that is, to have a sampling rate higher than the minimum requi...
متن کاملa study on thermodynamic models for simulation of 1,3 butadiene purification columns
attempts have been made to study the thermodynamic behavior of 1,3 butadiene purification columns with the aim of retrofitting those columns to more energy efficient separation schemes. 1,3 butadiene is purified in two columns in series through being separated from methyl acetylene and 1,2 butadiene in the first and second column respectively. comparisons have been made among different therm...
Simulation of Probability of False Alarm and Probability of Detection Using Energy Detection in Coginitive Radio
The rapid growth of wireless devices and application has contributed to huge demand for licensed and unlicensed frequency spectrum. However, recent studies exhibits that restricted spectrum assignment policy results in congestion for spectrum utilization under which considerable portion of the licensed spectrum is severely under-utilized. To address this problem, Cognitive radio is a paradigm f...
متن کاملFalse Alarm Constrained Classification
In classification problems, the goal is often to maximize the probability of a true positive while satisfying a system design constraint on the number of false alarms. Current classifiers, which are based on minimizing classification error, achieve this goal indirectly by either shifting the bias of the resulting solution or via tuning of an asymmetry parameter. While these approaches may be us...
