Multifractal Image Analysis of Electrostatic Surface Microdischarges
Acta Polytechnica, 2004 The multifractal image analysis of Lichtenberg figures has confirrmed a self- similar arrangement of surface streamers belonging to the special case of electrostatic separation discharges propagating along a surface of polymeric dielectrics.

Large Deviations and the Distribution of Price Changes [PDF]
The Multifractal Model of Asset Returns ("MMAR," see Mandelbrot, Fisher, and Calvet, 1997) proposes a class of multifractal processes for the modelling of financial returns.

Multifractional correlation is proposed that is based on a new generalized fractional Fourier transform to which we refer as a multifractional Fourier transform. The multifractional correlation yields remarkable improvements in the correlation output peak intensity, peak sharpness, and light efficiency compared with convention correlation, which uses ...

Multiscaling is shown to be a consequence of multifractality when a lower cutoff ∈ is introduced in calculations of correlation functions. After a suitable rescaling, the correlation function data for different values of ∈ seem to fall onto a single curve.

Consistent scaling of multifractal measures: Multifractal spatial correlations
Physical Review E, 1993There are a number of apparently disparate problems in multifractal scaling whose solutions have remained unclear, ranging from rather pathological cases where the standard Legendre transformations do not produce effective measures for the H\"older exponent and Hausdorff-Besicovitch dimension to the problem of describing the scaling of point-point ...

We present multifractal zone plates (MFZPs) as what is to our knowledge a new family of diffractive lenses whose structure is based on the combination of fractal zone plates (FZPs) of different orders. The typical result is a composite of two FZPs with the central one having a first-order focal length f surrounded by outer zones with a third-order ...
