Wavelet Application in Process monitoring

摘要

A methodology is presented that makes use of wave- let bases as a means for computing the probability den- sity functions associated with different system states in a nuclear environment. Multiresolution analysis is cou- pled with multivariate statistics to form a tool powerful enough to estimate multidimensional density functions from highly correlated system variable. Wavelets that adapt well to local characteristics of rapidly varying func- tions are employed as building blocks of the proposed approach.
