The major problem in the seismology is to get a better estimation of ground velocity and displacement from acceleration time-histories. The real problem in the estimation is on processing of the accelerographs that records the acceleration of ground movements against time with tilt, causes baseline offset. This book discuss about the tilt separation and de-noising by the TS-ICA model that covers several source distribution such as Normal, Gaussian, non-Gaussian, Sub and Super Gaussian and skewed distribution with zero kurtosis and derives an alternative for a better estimates of ground...
