Non-parametric linear time-invariant system identification by discrete wavelet transforms
, 2006 We describe the use of the discrete wavelet transform (DWT) for non-parametric linear time-invariant system identification. Identification is achieved by using a test excitation to the system under test (SUT) that also acts as the analyzing function for ...

On the block wavelet transform applied to the boundary element method [PDF]
, 2004 This paper follows an earlier work by Bucher et al. [1] on the application of wavelet transforms to the boundary element method, which shows how to reuse models stored in compressed form to solve new models with the same geometry but arbitrary load cases

Condition Monitoring of Induction Machines: Quantitative Analysis and Comparison
Sensors, 2023 In this paper, a diagnostic procedure for rotor bar faults in induction motors is presented, based on the Hilbert and discrete wavelet transforms. The method is compared with other procedures with the same data, which are based on time–frequency analysis,
