VMD and CNN-Based Classification Model for Infrasound Signal
Published 2023-08-01Get full textInfrasound signal classification is vital in geological hazard monitoring systems. The traditional classification approach extracts the features and classifies the infrasound events. However, due to the manual feature extraction, its classification performance is not satisfactory. To deal with this...

Infrasound Signal Classification Based on ICA and SVM
Published 2023-05-01Get full textA diagnostic technique based on independent component analysis (ICA), fast Fourier transform (FFT), and support vector machine (SVM) is suggested for effectively extracting signal features in infrasound signal monitoring. Firstly, ICA is proposed to separate the source signals of mixed infrasound so...

Digital Twin and Data-Driven Remaining Useful Life Prediction of Gearbox
Published 2025-01-01Get full textTraditional approaches for predicting the remaining useful life (RUL) of gearboxes often face challenges in integrating physical and virtual data, leading to reduced prediction accuracy and an increased risk of system failure. To realize reliable RUL prediction of gearbox, this paper proposes a nove...
