Research on Image Encryption Based on Fractional Seed Chaos Generator and Fractal Theory
Fractal and Fractional, 2023 In this paper, a new fractional-order seed chaotic generator is designed to solve the problem of the complex operations of single low-dimensional systems and simple high-dimensional systems. The fractional-order chaotic system generated is proven to have

Mathematical Model for Effective Gas Diffusion Coefficient in Multi-scale Fractal Porous Media [PDF]
E3S Web of Conferences, 2021 Based on the capillary hypothesis and fractal theory, a mathematical model for calculating the effective gas diffusion coefficient in porous media is established. By using fractal geometry theory, pore area fractal dimension, tortuosity fractal dimension

Fractal Model of Contact Thermal Stiffness
Machines, 2022 The continuity, self-similarity, and self-affinity of a microscopic contact surface can be described by the Weierstrass–Mandelbrot (W–M) function in fractal theory. To address the problems that the existing normal contact load fractal model does not take

Urban spatial form analysis based on the architectural layout -- Taking Zhengzhou City as an example
PLoS ONE, 2022 The analysis of urban spatial form is the basic research of urban development. Traditional fractal research often focuses on the urban spatial layout, which cannot visually express the specific form, change characteristics and development trend of urban ...
