Hyperspectral image analysis using multifractal attributes [PDF]
, 2015 International audienceThe increasing spatial resolution of hyperspectral remote sensors requires the development of new processing methods capable of combining both spectral and spatial information.In this article, we focus on the spatial component and ...

Fluctuating Interfaces in Barotropic Beta‐Plane Turbulence
Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.Abstract Zonal jets manifest themselves as bands with sharp interfaces in the vorticity configuration. We develop an algorithm to track these fluctuating vorticity interfaces and systematically investigate their characteristic spatio‐temporal behaviors.

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract Turbulent winds are a regular occurrence in planetary boundary layers. Turbulence affects mixing, energy fluxes and forcing on the surface environment. Energy injected into an atmosphere generates eddies of many scales down to a size where molecular viscous forces dominate, termed the Kolmogorov length scale.

Multifractal variability in geoelectrical signals and correlations with seismicity: a study case in southern Italy [PDF]
Natural Hazards and Earth System Sciences, 2005 Multifractal fluctuations in the time dynamics of geoelectrical data, recorded in a seismic area of southern Italy, have been revealed using the Multifractal Detrended Fluctuation Analysis (MF-DFA), which allows to detect multifractality in nonstationary

Multifractal analysis of DNA [PDF]
Conference Proceedings. IEEE Canadian Conference on Electrical and Computer Engineering (Cat. No.98TH8341), 2002 This paper presents a multifractal analsyis technique for deoxyribonucleic acid (DNA). A brief overview of sequencing and multifractal measures is given along with multifractal spectrum data. Fractal characterization is shown to have high potential as a valuable tool in DNA analysis.
