Leakage-Free, Cross-Speed, and Cross-Session Evaluation of Vibration-Based Propulsion-Shaft Misalignment Diagnosis in Electric Ships: A Real-Time Detect-Then-Grade Cascade

Vibration-based diagnosis of propulsion-shaft misalignment supports condition monitoring in electric ships, but reported accuracies are often inflated by overlapping-window leakage and by untested cross-recording, cross-session, and cross-speed generalization. We evaluated leakage-free, deployment-oriented protocols (c...
