Modern Paradigm Regarding Capital Markets: Fractal Market Hypothesis. Determination of the Hurst Exponent on the Romanian Capital Market

open access: yesEIRP Proceedings, 2022
Classical statistical and econometric theory, intended to provide functional forecasting models in capital markets, is the mathematical foundation for a number of theories - efficient market theory, Harry Markowitz's optimized portfolio theory, the ...

Dimensions, Maximal Growth Sites and Optimization in the Dielectric Breakdown Model [PDF]

open access: yes, 2008
We study the growth of fractal clusters in the Dielectric Breakdown Model (DBM) by means of iterated conformal mappings. In particular we investigate the fractal dimension and the maximal growth site (measured by the Hoelder exponent $\alpha_{min}$) as a

Fractal Pharmacokinetics [PDF]

open access: yesComputational and Mathematical Methods in Medicine, 2009
Pharmacokinetics (PK) has been traditionally dealt with under the homogeneity assumption. However, biological systems are nowadays comprehensively understood as being inherently fractal. Specifically, the microenvironments where drug molecules interact with membrane interfaces, metabolic enzymes or pharmacological receptors, are unanimously recognized ...

Fractal analysis of fractograms of aluminum alloys irradiated with high current electron beam

open access: yesФізика і хімія твердого тіла, 2023
The aluminum alloys D16 and AMg6 were irradiated using the high-current relativistic electron beam in vacuum. Intense electron irradiation of the materials modified their physical properties.

The scattering from generalized Cantor fractals

open access: yes, 2010
We consider a fractal with a variable fractal dimension, which is a generalization of the well known triadic Cantor set. In contrast with the usual Cantor set, the fractal dimension is controlled using a scaling factor, and can vary from zero to one in ...

Helicalised fractals

open access: yes, 2015
We formulate the helicaliser, which replaces a given smooth curve by another curve that winds around it. In our analysis, we relate this formulation to the geometrical properties of the self-similar circular fractal (the discrete version of the curved ...

Deterministic fractals: extracting additional information from small-angle scattering data

open access: yes, 2011
The small-angle scattering curves of deterministic mass fractals are studied and analyzed in the momentum space. In the fractal region, the curve I(q)q^D is found to be log-periodic with a good accuracy, and the period is equal to the scaling factor of ...

Abstract Fractals

open access: yesThe interdisciplinary journal of Discontinuity, Nonlinearity, and Complexity, 2021
We develop a new definition of fractals which can be considered as an abstraction of the fractals determined through self-similarity. The definition is formulated through imposing conditions which are governed the relation between the subsets of a metric space to build a porous self-similar structure.
