Weak Feature Extraction of Rolling Bearing Fault Based on Generalized Variational Mode Decomposition

Jixie chuandong, 2023
Aiming at the deficiency of variational mode decomposition (VMD) in on-demand extraction of weak feature components, a generalized VMD (GVMD) is proposed to extract the weak features of rolling bearing faults.

A Multi‐Scale Probabilistic Machine Learning Model for Balanced and Unbalanced Sea Surface Height Decomposition

Journal of Geophysical Research: Machine Learning and Computation
Sea surface height (SSH) reflects a superposition of balanced motions (BM) and unbalanced motions (UBM), which play distinct roles in ocean dynamics and energetics. The Surface Water and Ocean Topography (SWOT) satellite provides two‐dimensional SSH maps

Multi scale modal decomposition of primary form, waviness and roughness of surfaces [PDF]

Scanning, 2011
AbstractThis article introduces an innovative method for the multi‐scale analysis of high value‐added surfaces, which consists of applying a method based on a new parameterization. This kind of surface parameterization refers to natural modes of vibration, and is therefore named modal parameterization.

Electrical‐Programming‐Free Neural Crossbars Enabled by Photochemical Weight Patterning

Advanced Functional Materials, EarlyView.
A flexible neural‐crossbar hardware system enabled by electrical‐programming‐free, mask‐defined, array‐parallel photochemical weight patterning is demonstrated. Trained weights are physically implemented across the array, supporting multilevel programming, bending‐stable operation and reconfiguration, substrate reuse, and low‐energy readout while ...
