Local scaling property of seismicity: an example of getting valuable information from complex hierarchical system [PDF]

open access: yesNonlinear Processes in Geophysics, 2010
In order to get valuable information about the scale invariance in the process of seismogeny of Lijiang <i>M</i> 7.0 earthquake, the scaling property of the interevent time series of the seismic sequences for Lijiang area in China were ...

Spatial Signal Analysis Based on Wave-Spectral Fractal Scaling: A Case of Urban Street Networks

open access: yesApplied Sciences, 2020
A number of mathematical methods have been developed to make temporal signal analyses based on time series. However, no effective method for spatial signal analysis, which are as important as temporal signal analyses for geographical systems, has been ...

Scaling of fracture systems in geological media [PDF]

open access: yes, 2001
Scaling in fracture systems has become an active field of research in the last 25 years motivated by practical applications in hazardous waste disposal, hydrocarbon reservoir management, and earthquake hazard assessment.

Interactive rhythmic auditory stimulation reinstates natural 1/f timing in gait of Parkinson's patients. [PDF]

open access: yesPLoS ONE, 2012
Parkinson's disease (PD) and basal ganglia dysfunction impair movement timing, which leads to gait instability and falls. Parkinsonian gait consists of random, disconnected stride times--rather than the 1/f structure observed in healthy gait--and this ...

Dynamic scaling on fractals with sublattices

open access: yesJournal of Physics A: Mathematical and General, 1986
Dynamic scaling techniques are developed for antiferromagnets and multiatomic lattices. The methods are applied to antiferromagnets and triatomic lattices on Sierpinski gasket fractals, and to ferro- and antiferromagnets on Berker hierarchical lattices. Relationships between the frequencies of ferro- and antiferromagnets on the same fractal and of mono-

On the multi-fractal scaling properties of sea ice deformation

open access: yesThe Cryosphere, 2019
. In this paper, we evaluate the neXtSIM sea ice model with respect to the observed scaling invariance properties of sea ice deformation in the spatial and temporal domains.

On the fractal nature of the magnetic field energy density in the solar wind [PDF]

open access: yes, 2007
The solar wind exhibits scaling typical of intermittent turbulence in the statistics of in situ fluctuations in both the magnetic and velocity fields.

Characterizing Growth and Form of Fractal Cities with Allometric Scaling Exponents

open access: yesDiscrete Dynamics in Nature and Society, 2010
Fractal growth is a kind of allometric growth, and the allometric scaling exponents can be employed to describe growing fractal phenomena such as cities. The spatial features of the regular fractals can be characterized by fractal dimension. However, for
