To alleviate data distribution under different operating conditions, domain generalization (DG) has been applied in mechanical diagnosis. Still, its effectiveness is limited when unknown fault states appear the target domain. Consequently, open set DG (OSDG) emerged to identify classes domains. However, collection costs and safety concerns have resulted a significant class imbalance OSDG. This causes decision boundary be skewed toward abundant positive classes, ultimately leading...
Differential-mode and common-mode chokes (DMC CMC) are key components of electromagnetic interference filters. Accurate impedance knowledge these allows optimal EMI filter design to meet the conducted emission requirements. An analyzer or vector network with a fixture adapter is commonly adopted for measurement passive component. Usually, non-standard terminals both DMC CMC make them incompatible direct mounting on commercially available adapters. Relying additional interconnects adapters...
