Monofractal or multifractal:a case study of spatial distribution of mining-induced seismic activity
spatial distribution mining-induced seismic activity
2009/11/16
Using finite data sets and limited size of study volumes may result in significant spurious effects when estimating the scaling properties of various physical processes. These effects are examined wit...
Multifractal structure of the large-scale heliospheric magnetic field strength fluctuations near 85AU
Multifractal structure magnetic field strength fluctuations 85AU
2009/11/11
During 2002, the Voyager 1 spacecraft was in the heliosphere between 83.4 and 85.9AU (1AU is the mean distance from the Sun to Earth) at 34° N heliographic latitude. The magnetic field strength profil...
Multifractal analysis for the ULF geomagnetic data during the 1993 Guam earthquake
Multifractal analysis ULF geomagnetic data Guam earthquake
2009/11/9
In our previous papers we have shown that the fractal (monofractal) dimension (Do) showed a significant increase before the Guam earthquake occurred on 8 August, 1993. In order to have a further suppo...
This paper shows how modern ideas of scaling can be used to model topography with various morphologies and also to accurately characterize topography over wide ranges of scales. Our argument is divide...
Representative elementary area for multifractal analysis of soil porosity using entropy dimension
Representative elementary area multifractal analysis soil porosity entropy dimension
2009/11/3
The notion of representative elementary area (REA) developed to address heterogeneity and scale problems in quantitative soil pedology comes from the notion of representative elementary volume of flui...
Multifractal imaging filtering and decomposition methods in space,Fourier frequency,and eigen domains
ultifractal imaging filtering decomposition methods Fourier frequency eigen domains
2009/11/3
The patterns shown on two-dimensional images (fields) used in geosciences reflect the end products of geo-processes that occurred on the surface and in the subsurface of the Earth. Anisotropy of these...
Asymmetric multifractal model for solar wind intermittent turbulence
Asymmetric multifractal model solar wind intermittent turbulence
2009/11/2
We consider nonuniform energy transfer rate for solar wind turbulence depending on the solar cycle activity. To achieve this purpose we determine the generalized dimensions and singularity spectra for...
Assessing soil surface roughness decay during simulated rainfall by multifractal analysis
soil surface roughness decay simulated rainfall multifractal analysis
2009/11/2
Understanding and describing the spatial characteristics of soil surface microrelief are required for modelling overland flow and erosion. We employed the multifractal approach to characterize topogra...
