Study on the Screening Efficiency for the Probability Screen

Abstract: The evolution of the screening efficiency for the probability screen was given in this paper. Trispectrum based on AR model was estimated with the vibration signal obtained from the probability screen. The relevance between trispectral slices and screening efficiency was analyzed qualitatively. The evolution of screening efficiency was also discussed in detail with a statistical quantity, i.e., kurtosis(K); In addition, the relationship between the correlation dimension and screening efficiency was analyzed quantitatively. The results show that the relevance between the spectral characteristics and screening efficiency is consistent with the relationship between the correlation dimension and screening efficiency.
