Estimation of parameter k(max) in fractal analysis of rat brain activity
(New York Acad Sciences, New York, 2005)
We recorded electrocortical activity in anesthetized rats and constructed kmax new self-similar time series, applying Higuchi's algorithm. The aim of this study was to estimate value of the parameter k(max). in order to ...
Fractal analysis of rat brain activity after injury
(Springer Heidelberg, Heidelberg, 2005)
With application of the Higuchi algorithm, fractal dimension (FD) values of the electrocortical activity of the rat parietal cerebral and paravermal cerebellar cortex were calculated, before and after unilateral discrete ...
Consecutive differences as a method of signal fractal analysis
(World Scientific Publ Co Pte Ltd, Singapore, 2005)
We propose a new method for calculating fractal dimension (DF) of a signal y(t), based on coefficients m(y)((n)), mean absolute values of its nth order derivatives (consecutive finite differences for sampled signals). We ...
