Spectral Analysis of Electricity Demand Using Hilbert–Huang Transform [PDF]

open access: yesSensors, 2020
The large amount of sensors in modern electrical networks poses a serious challenge in the data processing side. For many years, spectral analysis has been one of the most used approaches to extract physically meaningful information from a sea of data ...

Spectral denoising based on Hilbert–Huang transform combined with F-test [PDF]

open access: yesFrontiers in Chemistry, 2022
Due to the influence of uncontrollable factors such as the environment and instruments, noise is unavoidable in a spectral signal, which may affect the spectral resolution and analysis result.

A Revised Hilbert–Huang Transform and Its Application to Fault Diagnosis in a Rotor System [PDF]

open access: yesSensors, 2018
As a classical method to deal with nonlinear and nonstationary signals, the Hilbert–Huang transform (HHT) is widely used in various fields. In order to overcome the drawbacks of the Hilbert–Huang transform (such as end effects and mode mixing) during the

Horizontal-to-Vertical Spectral Ratio of Ambient Vibration Obtained with Hilbert–Huang Transform [PDF]

open access: yesSensors, 2021
The Horizontal-to-Vertical Spectral Ratio (HVSR) of ambient vibration measurements is a common tool to explore near surface shear wave velocity (Vs) structure. HVSR is often applied for earthquake risk assessments and civil engineering projects.
