Abstract
This paper presents Fourier and wavelet methods applied to data derived from Positron Emission Particle Tracking (PEPT) experiments conducted at the iThemba LABS outside Cape Town in South Africa. The iThemba LABS runs a specialized cyclotron which produces positrons for use in medical PET and industrial-related PEPT research. The methods are applied as an aid in developing a computational procedure for determining the value of the circulation rates of the charge found in typical industrial tumbling mills. The circulation rate values are obtained as fundamental harmonics from power spectral plots using Fourier analysis. The wavelet method is applied to identify and remove noise from the data in order to improve on the computationally determined value of the circulation rate. For the analysis presented herein, parameters are obtained directly from the flow dynamics of the PEPT tracer particle.
