However, where information such as the speed of rotating machinery, component specifications or other domain-specific information is unavailable, such methods are often infeasible. Thus, this paper investigates the application of classical time-domain features, features from the medical field and novel features from the highly comparative time-series analysis (HCTSA) package, for the health state estimation of rotating machinery operating under varying conditions. Furthermore, several feature selection methods are investigated to identify features as viable health indicators for the diagnostics and prognostics of technical systems. As a case study, the presented methods are evaluated on real-world and experimentally acquired vibration data of bearings operating under varying speed. The results show that the selected features can successfully be employed as health indicators for technical systems operating under varying conditions."}],"language":[{"iso":"eng"}],"publication_status":"inpress","type":"conference","user_id":"9557","quality_controlled":"1","keyword":["Wind turbine diagnostics","bearing diagnostics","non-stationary operating conditions","varying operating conditions","feature extraction","feature selection","fault detection","failure detection"],"status":"public","citation":{"apa":"Aimiyekagbon, O.
