The extraction of weak bearing fault features remains a formidable challenge in the field of mechanical health monitoring, particularly under strong background noise and non-periodic random shocks. Although blind deconvolution methods can effectively eliminate transmission path effects, their reliability is severely re...

Industrial robot grasping faces several key challenges, such as subtle anomaly features, scarce abnormal samples, significant domain shifts in training trajectories, and constrained edge computing capacities. To address these issues, this study introduces an unsupervised anomaly detection method, namely the physical re...

Early fault signatures of rolling bearings are typically very weak and are often contaminated by strong background noise and random impulsive interference. Traditional kurtosis-based feature extraction methods are highly sensitive to non-fault-related large random impacts, which may result in incorrect frequency-band s...
