Application of Arbitrary-Order Hilbert Spectral Analysis to Passive Scalar Turbulence [PDF]
Journal of Physics: Conference Series, 2011 In previous work [Huang et al., PRE 82, 26319, 2010], we found that the passive scalar turbulence field maybe less intermittent than what we believed before.

Spectral analysis of the truncated Hilbert transform with overlap [PDF]
SIAM Journal on Mathematical Analysis, 2013 We study a restriction of the Hilbert transform as an operator $H_T$ from $L^2(a_2,a_4)$ to $L^2(a_1,a_3)$ for real numbers $a_1 < a_2 < a_3 < a_4$. The operator $H_T$ arises in tomographic reconstruction from limited data, more precisely in the method ...

Analysis and Characterization of Power System Nonlinear Oscillations Using Hilbert Spectral Analysis [PDF]
The Open Electrical & Electronic Engineering Journal, 2007 In this contribution, a systematic approach to analyze and characterize the temporal evolution of nonlinear, time-varying processes in power systems is developed. The method combines the Hilbert-Huang transform and concepts from vibrating systems theory and can be used to approximate the dynamic behavior of quasi-stationary oscillations.

Comparison between traditional fast Fourier transform and marginal spectra using the Hilbert–Huang transform method for the broadband spectral analysis of the electroencephalogram in healthy humans [PDF]
Engineering Reports, 2021 The fast Fourier transform (FFT) has been the main tool for electroencephalographic (EEG) Spectral Analysis (SPA). However, as the EEG dynamics show nonlinear and non‐stationary behavior, results using the FFT approach may result meaningless.

Hilbert–Huang Spectral Analysis of Cavity Flows Incorporating Fluidic Spoilers
AIAA Journal, 2022 Numerical aeroacoustic analysis was conducted on an M219 cavity geometry, incorporating signature suppression features and leading-edge fluidic spoilers. The numerical model was validated against existing experimental data. The palliative properties of fluidic spoilers were investigated at Mach numbers of 0.85, 1.20, and 1.80 with blowing coefficients
