Wavelet-based detection and classification of roof-corner pressure transient

Abstract
Many practical time series, including pressure signals measured on roof-corners of low-risernbuildings in quartering winds, consist of relatively quiescent periods interrupted by intermittent transients.rnThe dyadic wavelet transform is used to detect these transients in pressure time series and a relativelyrnsimple pattern classification scheme is used to detect underlying structure in these transients. Statisticalrnanalysis of the resulting pattern classes yields a library of signal
