I am setting up an ANN to analyse waveforms resulting from ultra-high 
frequency non-destructive testing of composite materiels.

I would like some pointers to info on successful projects that are similar.

We currently are using Infometric's Testpro acoustic ultrasonic NDT 
system.  This system generates acoustic echo waveforms that are processed 
(windowed, noise gated, FFT'd, etc.) and analysed by trained experts.  We 
would like to emulate the experts with an ANN.  

I have some papers that talk about use of ANNs for 
concrete-defect analysis that were successful. 
More of these kind of citations would be greatly appreciated.
