Fault Detection of Motorcycles Using the Slopes of the Estimated Pseudospectrum of the Produced Sounds
The service experts assess the condition of the vehicles based on the produced sound. To benefit both, the riders and the experts, the fault diagnosis process needs to be automated. The paper presents a methodology for fault detection of motorcycles, which uses the slopes of the eight pseudospectral segments as features. The computed features are classified into healthy and faulty using artific...
متن کاملAcoustic Pseudospectrum Based Fault Localization Inmotorcycles
Vehicles generate dissimilar sound patterns under different health conditions. The sound generated by the vehicles gives a clue of some of the faults. Automotive experts diagnose the faults in vehicles based on the produced sound. This paper presents a methodology for fault source localization in motorcycles using the estimated pseudospectra of the sound signals. The pseudospectra are traced to...

Acoustic detection of apple mealiness based on support vector machine
Mealiness degrades the quality of apples and plays an important role in fruit market. Therefore, the use of reliable and rapid sensing techniques for nondestructive measurement and sorting of fruits is necessary. In this study, the potential of acoustic signals of rolling apples on an inclined plate as a new technique for nondestructive detection of Red Delicious apple mealiness was investigate...
متن کاملFault Detection and Localization in Motorcycles Based on the Chain Code of Pseudospectra and Acoustic Signals
Vehicles produce sound signals with varying temporal and spectral properties under different working conditions. These sounds are indicative of the condition of the engine. Fault diagnosis is a significantly difficult task in geographically remote places where expertise is scarce. Automated fault diagnosis can assist riders to assess the health condition of their vehicles. This paper presents a...
