A review of nonparametric attenuation functions computed for different regions of Italy
Seismic attenuation S waves non-parametric inversio acceleration spectra
2015/10/8
We used a set of previously published nonparametric attenuation functions to calculate average functions for the Italian region. These nonparametric functions describe the spectral amplitude decay of ...
Determination of electrical signal masked by random noise using «super-averaged» functions
Electrical methods electromagnetic methods data acquisitions data processing signal to-noise radio
2015/9/28
Electrical and electromagnetic methods often require the determination of the amplitude of a periodic signal,produced by controlled sources and masked by natural and artificial noise. Since noise is u...
Comparison of analytical functions used to describe topside electron density profiles with satellite data
topside ionosphere ionospheric modeling ionospheric layer formulation top side soundings
2015/9/10
Electron density models of the ionosphere use different analytical formulations for the electron density vertical
profile in the topside. The present paper compares some single-layer topside analytic...

Three‐dimensional FEM derived elastic Green’s functions for the coseismic deformation of the 2005Mw8.7 Nias‐Simeulue, Sumatra earthquake
Green’s functions coseismic deformation finite element model
2014/4/9
Using finite element models (FEMs), we examine the sensitivity of surface displacements to the location of fault slip, topography, and three‐dimensional variations in elastic moduli in the context of ...
Identifying sets of acceptable solutions to non-linear,geophysical inverse problems which have complicated misfit functions
sets of acceptable solutions non-linear,geophysical inverse problems misfit functions
2009/11/16
A goal of geophysical inversion is to identify all models which give an acceptable misfit between predicted and observed data. However, because of the complexity of Earth structure, the non-linearity ...

Scaling collapse structure functions self-affinity finite length time series
2009/11/11
Empirical determination of the scaling properties and exponents of time series presents a formidable challenge in testing, and developing, a theoretical understanding of turbulence and other out-of-eq...
