WebThe fundamental solution of the three-dimensional Hausdorff derivative diffusion equation is closely related to scaling transform and non-Euclidean Hausdorff fractal distance. The used method, as a meshless technique, is simple, accurate and efficient for solving the partial differential equations with fundamental solutions. WebThe order of the Hausdorff fractal derivative is designed to characterize the influence of the multi-fractal turbulence structure on sediment diffusion. Applications show that the …

WebDec 5, 2016 · Fractal derivative and operator In this article, we employ the definition of Hausdorff fractal derivative defined by Chen.30 Definition 1. Fractal derivative df(t) dta = lim t!t0 f(t) f(t0) ta t0a ð1Þ where a is the order of fractal derivative, represented a fractal measure; t denotes the coordinate in time. We WebIn mathematics, Hausdorff measure is a generalization of the traditional notions of area and volume to non-integer dimensions, specifically fractals and their Hausdorff dimensions.It is a type of outer measure, named for Felix Hausdorff, that assigns a number in [0,∞] to each set in or, more generally, in any metric space..

WebAug 1, 2015 · Then the fractal dimension IV of F is defined by dim Γ 4 ( F) = inf { s: H 4 s ( F) = 0 } = sup { s: H 4 s ( F) = ∞ }. To simplify the notation, in this paper we will write dim … WebSep 24, 2024 · Unlike the fractional derivative, the Hausdorff derivative, also known as fractal derivative, is a local differential operator instead of the global fractional derivative. Thus, its computational costs are far less than the global fractional derivative, in particular, for long-history and large-scale problems. WebApr 12, 2024 · This study presents a novel coupled meshless model for simulating acoustic wave propagation in heterogeneous media, based on the singular boundary method (SBM) and Kansa’s method (KS). In the proposed approach, the SBM was used to model the homogeneous part of the propagation domain, while KS was employed to model a … plastic food container symbols
