Theoretical and applied environmental sounds research is gaining prominence but progress has been hampered by the lack of a Cumin comprehensive, high quality, accessible database of environmental sounds.An ongoing project to develop such a resource is described, which is based upon experimental evidence as to the way we listen to sounds in the worl
Prediction and analysis of bearing vibration signal with a novel gray combination model
Bearings are the core components of ship propulsion shafting, and effective prediction of their working condition is crucial for reliable operation of the shaft system.Shafting vibration signals can accurately represent the running condition of bearings.Therefore, in this article, we propose a new model that can reliably predict the vibration signa
