Digital Bispectral Analysis and Its Applications to Nonlinear Wave Interactions
Young C. Kim,Edward J. Powers +1 more
TL;DR: The bispectrum, which is an ensemble average of a product of three spectral components, is shown to be a very useful diagnostic tool in experimental studies of nonlinear wave interactions in random media.

Edge turbulence measurements in toroidal fusion devices
S. J. Zweben,Jose Boedo,Olaf Grulke,C. Hidalgo,Brian LaBombard,R. J. Maqueda,P. Scarin,J. L. Terry +7 more
TL;DR: In this article, the authors reviewed measurements of edge plasma turbulence in toroidal magnetic fusion devices with an emphasis on recent results in tokamaks, showing that the dominant feature of edge turbulence is a high level of broadband density fluctuations with a relative amplitude δn/n ~ 5-100%.

Estimation of the magnitude-squared coherence function via overlapped fast Fourier transform processing
G. Carter,C. Knapp,A. Nuttall +2 more
TL;DR: In this paper, a method for estimating the magnitude-squared coherence function for two zero-mean wide-sense-stationary random processes is presented, which utilizes the weighted overlapped segmentation fast Fourier transform approach.

Experimental determination of the spectral index of a turbulent plasma from digitally computed power spectra
D. E. Smith,E. J. Powers +1 more
TL;DR: In this paper, the spectral index of the turbulent plasma was determined by using power spectra, and the existence of a linear relationship between k and ω was verified using a linear model.
Journal ArticleDOI
Turbulent diffusion coefficients of toroidal plasmas
TL;DR: In this paper, the difussion coefficient of a plasma with density gradient-produced fluctuations was calculated using two different methods of deriving the diffusion coefficients, and the condition that two methods yield the same result was used to determine the phase angle a between the density and the potential fluctuations.
