We present a method of data reduction using a wavelet transform in discriminant analysis when the number of variables is much greater than the number of observations. The method is illustrated with a ...

An important property of wavelet analysis is perfect reconstruction, which is the process of reassembling a decomposed signal or image into its original form without loss of information.

The structure of the dome includes an internal thick dome and an external thin one. In an effort to understand the dynamics of the crack widths we apply wavelet packet variance analysis to ...
