Abstract The Auxiliary Power Unit (APU) is an integral part of an aircraft, providing electrical
and pneumatic power to various on-board sub-systems. APU failure results in delay or …

The marvelous uniqueness of vibration responses of faulty roller bearings can be simply
observed through its vibration signature. Therefore, vibration analysis has been claimed as …

The existing intelligent monitoring methods are hard to apply directly to hydraulic machinery
due to fault data collection difficulties and the uncertainty of fault occurrence. To monitor the …

Blockages in the centrifugal pump, either upstream or downstream, reduce the pump's flow
rate, and if left unnoticed for prolong periods, it can result in cavitation and overheating …

Reciprocating compressors and centrifugal pumps are rotating machines used in industry,
where fault detection is crucial for avoiding unnecessary and costly downtime. A novel …

Methods for fault diagnosis based on metric learning, in which a query sample is classified
by picking the closest prototype from the support set based on their feature similarities, have …

Essential service water pumps are necessary safety devices responsible for discharging
waste heat from containments through seawater; their condition monitoring is critical for the …

Background Bearing faults in centrifugal pumps usually result in periodically fluctuating
torque, which leads to flow instabilities, pressure pulsation, excessive heating, and even …

Firefighting pumps are a critical component of the firefighting system, which directly affects
the safety operation of the buildings. Current fault-diagnosing methods for firefighting pumps …

Fault detection and diagnosis, have been topics of great interest in both academia and
industry. A well-designed strategy can considerably save operating costs by minimizing …
