Fractal and Multifractal Features of Seismicity in the Central Zone of Chile: Comparing Intraplate and Interplate Datasets

open access: yesProceedings, 2020
A fractal and multifractal study on a sample of superficial interplate and intraplate earthquakes in the central zone of Chile is presented. Epicenter and hypocenter data are considered.

The Spatiotemporal Evolution of Rainfall Extremes in a Changing Climate: A CONUS‐Wide Assessment Based on Multifractal Scaling Arguments

open access: yesEarth's Future, 2022
Given the rapidly changing climate, accurate spatiotemporal information on the evolution of extreme rainfall events is required for flood risk assessment and the design of resilient infrastructure.

Decomposing Multifractal Crossovers [PDF]

open access: yesFrontiers in Physiology, 2017
Physiological processes-such as, the brain's resting-state electrical activity or hemodynamic fluctuations-exhibit scale-free temporal structuring. However, impacts common in biological systems such as, noise, multiple signal generators, or filtering by transport function, result in multimodal scaling that cannot be reliably assessed by standard ...

Multifractal modelling and simulation of rain fields exhibiting spatial heterogeneity [PDF]

open access: yesHydrology and Earth System Sciences, 2002
Spatial multifractals are statistically homogeneous random fields. While being useful to model geophysical fields exhibiting a high degree of variability and discontinuity and including rainfall, they ignore the spatial trends embedded in the variability

Automatic Evaluation of an Interwell-Connected Pattern for Fractured-Vuggy Reservoirs Based on Static and Dynamic Analysis

open access: yesEnergies, 2023
The types of fractured-vuggy reservoirs are diverse, with dissolution holes and fractures of different scales as the main reservoir spaces. Clarifying the connectivity between wells is crucial for improving the recovery rate of fractured-vuggy reservoirs

The Star Formation Law in a Multifractal ISM [PDF]

open access: yes, 2007
The surface density of the star formation rate in different galaxies, as well as in different parts of a single galaxy, scales nonlinearly with the surface density of the total gas.

Fractal Modeling and Fractal Dimension Description of Urban Morphology

open access: yesEntropy, 2020
The conventional mathematical methods are based on characteristic length, while urban form has no characteristic length in many aspects. Urban area is a scale-dependence measure, which indicates the scale-free distribution of urban patterns.

Multifractal Analysis of Reservoir Rock Samples Using 3D X-Ray Micro Computed Tomography Images

open access: yesIEEE Access, 2022
Characterizing heterogeneity in reservoir rocks at the pore scale is crucial to understand the flow patterns better, and estimate reservoir petrophysical properties such as porosity and permeability. This study introduces multifractals as descriptors for
