Multifractal detrended fluctuation analysis of magnitude series of seismicity of Kachchh region, Western India
Aggarwal, S.K.; Lovallo, Michele; Khan, P.K.; Rastogi, B.K. - In: Physica A: Statistical Mechanics and its Applications 426 (2015) C, pp. 56-62
The sequence of magnitudes of the earthquakes occurred in Kachchh area (Gujarat, Western India) from 2003 to 2012, has been analysed by using the multifractal detrended fluctuation analysis. The complete and the aftershock-depleted catalogues with minimum magnitude M3 were investigated. Both...

Asymptotics for spectral regularization estimators in statistical inverse problems
Bissantz, Nicolai; Holzmann, Hajo - In: Computational Statistics 28 (2013) 2, pp. 435-453
While optimal rates of convergence in L <Subscript>2</Subscript> for spectral regularization estimators in statistical inverse problems have been much studied, the pointwise asymptotics for these estimators have received very little consideration. Here, we briefly discuss asymptotic expressions for bias and variance...</subscript>

Continuum reconstruction of the pore scale microstructure for Fontainebleau sandstone
Latief, F.D.E.; Biswal, B.; Fauzi, U.; Hilfer, R. - In: Physica A: Statistical Mechanics and its Applications 389 (2010) 8, pp. 1607-1618
A stochastic geometrical modeling technique is used to reconstruct a laboratory scale Fontainebleau sandstone with a sidelength of 1.5 cm. The model reconstruction is based on crystallite properties and diagenetic parameters determined from two-dimensional images. The three-dimensional pore...
