Among the various environmental concerns, the aircraft noise item has been constantly growing in importance over the past years. Measures for its reduction at the source as well its mitigation around airports must take into account aspects of medicine and technical design as well as legal and land use planning aspects. Fan noise is one of the principal noise sources in turbofan aero-engines. In...

Understanding the remaining useful life (RUL) of equipment is crucial for optimal predictive maintenance (PdM). This addresses issues downtime and unnecessary checks in run-to-failure preventive maintenance. Both feature extraction prediction algorithm have played roles on performance RUL models. A benchmark dataset, namely Turbofan Engine Degradation Simulation Dataset, was selected analysis e...
