Examples of signals that could be modelled as piecewise constant (PWC) signals obscured by noise. (a) Log normalized DNA copy-number ratios against genome order from a microarray-based comparative genomic hybridization study (Snijders et al. 2001); (b) Cosmic ray intensity against time recorded by neutron monitor (O’Loughlin 1997); (c) rotation speed against time of R. Sphaeroides flagellum (Pilizota et al. 2009), (d) pixel red intensity value against horizontal pixel position for a single scan line from a digital image, (e) short-wavelength solar X-ray flux against time recorded by GOES-15 space weather satellite (Bloom 2009) and (f ) gamma ray intensity against depth from USGS wireline geological survey well log (Ryder et al. 2009).
