The Hilbert-Huang transform (HHT) is a method of spectral analysis that is suitable for application to nonstationary and non-linear signals that holds enormous potential for the analysis of turbulent flows in fluvial, aeolian, and coastal systems. HHT beg... see more

The article considers new technique called multimodal pressure flow method that utilizes Hilbert-Huang transformation to quantify interaction between nonstationary cerebral blood flow velocity and blood pressure for the assessment of dynamic cerebral auto... see more

The conversion of time domain data via the fast Fourier (FFT) and Hilbert-Huang (HHT) transforms is compared. The FFT treats amplitude vs. time information globally as it transforms the data to an amplitude vs. frequency description. The HHT is not constr... see more

The Hilbert-Huang transform (HHT) is a method of spectral analysis that is suitable for application to nonstationary and non-linear signals that holds enormous potential for the analysis of turbulent flows in fluvial, aeolian, and coastal systems. HHT beg... see more

Due to their very low noise levels in the low frequency band (<1 mHz), superconducting gravimeters (SGs) are particularly suitable to observe long-period free oscillations of the Earth. This case study is dedicated to the detection of the triplet of th... see more

The broad diffusion of renewable energy-based technologies has introduced several open issues in the design and operation of smart grids (SGs) when distributed generators (DGs) inject a large amount of power into the grid. In this paper, a theoretical inv... see more

 In this paper application of Hilbert-Huang transform (HHT) to electroencephalogram (EEG) signals analysis is presented, in order to simplify diagnosis of epilepsy. HHT consists of empirical mode decomposition (EMD) and Hilbert spectral analysis. Hil... see more

The Hilbert transform is a well-known tool of time series analysis that has been widely used to investigate oscillatory signals that resemble a noisy periodic oscillation, because it allows instantaneous phase and frequency to be estimated, which in turn ... see more
