Biomechanical Analysis of Golf Swing Motion Using Hilbert–Huang Transform [PDF]
Sensors, 2023 In golf swing analysis, high-speed cameras and Trackman devices are traditionally used to collect data about the club, ball, and putt. However, these tools are costly and often inaccessible to golfers.

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

Cutting force response in milling of Inconel: analysis by wavelet and Hilbert-Huang Transforms [PDF]
Latin American Journal of Solids and Structures, 2013 We study the milling process of Inconel. By continuously increasing the cutting depth we follow the system response and appearance of oscillations of larger amplitude.

Drilling-vibration response characteristics of rocks based on Hilbert–Huang transform [PDF]
Journal of Petroleum Exploration and Production Technology, 2023 Currently, there are no in-situ methods to quantify drilling-vibration response characteristics of different lithologies. Here, we quantified the vibration responses of four lithologies (limestone, sandstone, coal, and mudstone) using a combination of ...

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

The application of Hilbert–Huang transform energy spectrum in brushless direct current motor vibration signals monitoring of unmanned aerial vehicle [PDF]
Advances in Mechanical Engineering, 2016 Due to the characteristics of structure, brushless direct current motor has a long lifetime, which makes it more difficult to obtain failure data. Accordingly, valid degeneration characteristics are required in life prediction.
