Some nonlinear problems in plankton ecology
… motivated a generalization of fractals known as multifractals. Here, I give a first application of multifractals to biological oceanography. I analyze an acoustic data set on zooplankton biomass to describe the distribution in time of the total variability in the data. This distribution is highly …

A new model of spiral galaxies based on propagating star formation.
… analysis are encouraging, particularly for the multifractals, although it is not as yet possible to calculate a single, unique number which fully characterises the morphology.

Fractal Dimensions in Classical and Quantum Mechanical Open Chaotic Systems
Fractals have long been recognized to be a characteristic feature arising from chaotic dynamics; be it in the form of strange attractors, of fractal boundaries around basins of attraction, or of fractal and multifractal distributions of asymptotic measures in open systems. In this thesis we study …

Quantization Dimension for Probability Definitions
The term quantization refers to the process of estimating a given probability by a discrete probability supported on a finite set. The quantization dimension Dr of a probability is related to the asymptotic rate at which the expected distance (raised to the rth power) to the support of the …

A Dynamic and Thermodynamic Approach to Complexity.
The problem of establishing the correct approach to complexity is a very hot and crucial issue to which this dissertation gives some contributions. This dissertation considers two main possibilities, one, advocated by Tsallis and co-workers, setting the foundation of complexity on a generalized, …

Oceanic Rain Identification Using Multifractal Analysis Of Quikscat Sigma-0
The presence of rain over oceans interferes with the measurement of sea surface wind speed and direction from the Sea Winds scatterometer and as a result wind measurements contain biases in rain regions. In past research at the Central Florida Remote Sensing Lab, it has been observed that rain has …
