Fractal Dimension and Retinal Pathology: A Meta-analysis [PDF]
arXiv, 2021 Due to the fractal nature of retinal blood vessels, the retinal fractal dimension is a natural parameter for researchers to explore and has garnered interest as a potential diagnostic tool. This review aims to summarize the current scientific evidence regarding the relationship between fractal dimension and retinal pathology and thus assess the ...

Wave Equation for Fractal Solid String [PDF]
Modern Physics Letters B. Vol.19. No.15. (2005) 721-728, 2006 We use the fractional integrals to describe fractal solid. We suggest to consider the fractal solid as special (fractional) continuous medium. We replace the fractal solid with fractal mass dimension by some continuous model that is described by fractional integrals. The fractional integrals are considered as approximation of the integrals on fractals.

Dynamics of Fractal Solids [PDF]
International Journal of Modern Physics B. Vol.19. No.27. (2005)
4103-4114, 2007 We describe the fractal solid by a special continuous medium model. We propose to describe the fractal solid by a fractional continuous model, where all characteristics and fields are defined everywhere in the volume but they follow some generalized equations which are derived by using integrals of fractional order. The order of fractional integral can

Fractal dimension for a class of complex-valued fractal interpolation functions [PDF]
arXiv, 2022 There are many research papers dealing with fractal dimension of real-valued fractal functions in the recent literature. The main focus of the present paper is to study fractal dimension of complex-valued functions. This paper also highlights the difference between dimensional results of the complex-valued and real-valued fractal functions.

Fractal Dimension for Fractal Structures: A Hausdorff Approach [PDF]
arXiv, 2010 This paper provides a new model to compute the fractal dimension of a subset on a generalized-fractal space. Recall that fractal structures are a perfect place where a new definition of fractal dimension can be given, so we perform a suitable discretization of the Hausdorff theory of fractal dimension.

Stage Division of Urban Growth Based on Logistic Model of Fractal Dimension Curves [PDF]
arXiv, 2021 The time series of fractal dimension values of urban form always take on sigmoid curves. The basic model of these curves is logistic function. From the logistic model of fractal dimension curves, we can derive the growth rate formula and acceleration formula of city development.
