| Abstract: | Ii this puper surrogate tlata melhod of phase-ran-lollli=etl i3. l)rOPosed to identifythe random or chuotic naature of the data ohtained in dynamie anatysis. The cateulatingresults validale the phase-randomized method tc be useful as it ean increase the extentof accuraey of the results. And the calculating results show that threshold values of the random timeseries and nonlinear chuotic timeseries have marked differenee. |
