EEG Fractal Dimension Measurement before and after Human Auditory Stimulation

, 2009
The aim of this work is to investigate the change of fractal dimension Df with the help of Higuchi Fractal Dimension measure (HFD) in Event-Related Potentials (ERP) of human EEG time series, obtained as a result of oddball paradigm usage and auditory ...

Modeling of Color and Degradation of C‐Phycocyanin Extracted From Arthrospira platensis and Chlorogloeopsis HTF

Chemie Ingenieur Technik, EarlyView.
A nonlinear kinetic model was developed and successfully implemented, which describes the degradation of the protein C‐phycocyanin depending on temperature and pH value. C‐phycocyanin had been extracted from two different cyanobacteria. In addition to protein degradation, the fading of the typical blue color of this protein was included in the model ...

The Fractal Dimension of Taxonomic Systems

, 1990
The hypothesis that biological diversity has a fractal geometry is tested through the examination of size-frequency distributions of taxa with different numbers of subtaxa. Data used derive from 44 checklists and catalogues of species concerning protists,

An Analytical Design Model of a Vacuum Pressure Swing Adsorption Process for Biogas Upgrading

Chemie Ingenieur Technik, EarlyView.
A steady‐state model was developed for a vacuum pressure swing adsorption (VPSA) process comprising adsorption, depressurization, and evacuation steps. The resulting analytical plant design model provides the optimal adsorber height required to achieve a target product purity with maximum bed utilization.

Fractal Models for SAR images

, 2011
In this thesis the modeling of SAR (Synthetic Aperture Radar) images of natural surfaces described via fractal models is dealt with. A complete theoretical forward model linking the parameters describing the scene observed by the sensor to the stochastic

Resource‐Efficient Electrodes with Metallized Woven‐Glass‐Grid Current Collectors for Lithium‐Ion Batteries

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
The use of metallized glass‐based woven‐grids instead of metal foils as current collectors for LIBs leads to a significant reduction in metal usage by over 90 % and weight savings of more than 80 %, resulting in an 11 % increase in specific energy at the cell level. Abstract A novel class of resource‐efficient, woven‐glass‐grid current collectors (CCs)

Fractal dimensions of fractal transformations and quantization dimensions for bi-Lipschitz mappings

Journal of Fractal Geometry, Mathematics of Fractals and Related Topics
In this paper, we study the fractal dimension of the graph of a fractal transformation and also determine the quantization dimension of a probability measure supported on the graph of the fractal transformation. Moreover, we estimate the quantization dimension of the invariant measure corresponding to a weighted iterated function system consisting of ...

Manipulating drying‐induced carbon nanotube assemblies through substrate surface engineering

Droplet, EarlyView.
During the observation of CNT droplet drying on modified substrates with varying surface properties, high‐friction surfaces induced long‐range orientation of CNTs through fixed contact lines and material flow during evaporation. This provides a programmable substrate strategy for assembling ordered nanostructures via controlled droplet drying ...

The geometry of self-affine fractals

, 2008
In this thesis we study the dimension theory of self-affine sets. We begin by introducing a number of notions from fractal geometry, in particular, dimensions, measure properties and iterated functions systems.
