Application of Fuzzy Theory to Plasma Data Analysis

Abstract

To analyze correlations among time-series data in plasma experiments, the fuzzy theory has been applied. The method includes the standard spectral analysis as the simplest case, which is for statistically equilibrium fluctuations. A generalization made by the method extends to correlation analyses of various non-equilibrium fluctuations. Preliminary results of data analysis by the method has been obtained for the REPUTE-1 experiments.
