Fractal dimension of random attractor for stochastic non-autonomous damped wave equation with linear multiplicative white noise

, 2015
In this paper, we first present some conditions for bounding the fractal dimension of a random invariant set of a non-autonomous random dynamical system on a separable Banach space.

Quantification of Tortuosity and Fractal Dimension of the Lung Vessels in Pulmonary Hypertension Patients

PLoS ONE, 2014
Pulmonary hypertension (PH) can result in vascular pruning and increased tortuosity of the blood vessels. In this study we examined whether automatic extraction of lung vessels from contrast-enhanced thoracic computed tomography (CT) scans and ...

Spectral Asymmetry and Higuchi's Fractal Dimension Measures of Depression Electroencephalogram

Comput. Math. Methods Medicine, 2013
This study was aimed to compare two electroencephalogram (EEG) analysis methods, spectral asymmetry index (SASI) and Higuchi's fractal dimension (HFD), for detection of depression. Linear SASI method is based on evaluation of the balance of powers in two
