Formatted Abstract/Summary
Time-frequency (t, f) applications are now so widespread that they cannot be comprehensively covered in one volume. For this reason, this chapter aims to further illustrate the (t, f) approach by selecting a few key generic applications of diagnosis and monitoring. The topic is represented by seven sections covering a wide range of diverse applications. One key application is electrical power quality as it is often severely affected by transient disturbances. It is necessary to detect and assess their effect on voltage and current stability. This is achieved by a time-localized frequency analysis where the instantaneous frequency (IF) allows assessing disturbance propagation (Section 15.1). In the automotive industry, the treatment and prevention of knock is a major problem for internal combustion engines as car spark knocks caused by an abnormal combustion may lead to engine damage. The Wigner-Ville distribution is used to optimize the position for placement of knock sensors (Section 15.2). Other applications involve signals that have dispersive spectral delays governed by a power law, such as dispersive propagation of a shock wave in a steel beam and cetacean mammal whistles. A power class of TFDs suitable for such applications is formulated and a methodology is described (Section 15.3). In applications of image processing, image quality may be assessed using a 2D-WVD based measure correlated with subjective human evaluations. It is shown that this SNR measure based on the WVD outperforms conventional SNR measures (Section 15.4). Some general principles of (t, f) diagnosis are then reviewed for medical applications with focus on heart sound abnormality diagnosis (Section 15.5). For machine condition monitoring, a task crucial to the competitiveness of a wide range of industries, the tasks of detecting and diagnosing faults in machines, is made easier using (t, f) approaches such as the WVD, wavelets, and wavelet packets (Section 15.6). The last section presents a specific example of condition monitoring of assets using (t, f) methods that focus on the prevention of steel beam damage (Section 15.7).
