Current paper proposes a system for identifying bearing faults of a 3-phase induction motor operated in process control application along with the presence of other source of vibration, in the same process. Different types of bearing fault identification techniques have been discussed in literature with the analysis of time domain, frequency domain and time-frequency domain based features. The proposed...
The present work, propose a system for vibration signal analysis of 3-phase induction motor when controlled by Variable Frequency Drive (VFD), in process control operation. The motors used in process control operation are subjected to dynamic speed along with load variations, thus most often fault occurs in rotating elements such as bearing. In literature, various bearing fault identification technique...
This paper explores the role of facial asymmetry in identification tasks using a frequency domain representation. Satisfactory results are obtained for two different tasks, namely, human identification under extreme expression variations and expression classification, using a PCA-type classifier which establishes the robustness of these measures to intra-personal distortions. We next demonstrate that...
This paper explores the efficiency of facial asymmetry in face identification tasks using a frequency domain representation. Satisfactory results are obtained for two different tasks, namely, human identification under extreme expression variations and expression classification, using a PCA-type classifier on a database with 55 individuals, which establishes the robustness of these measures to intra-personal...
