A New Approach to Determining the Network Fractality with Application to Robot-Laser-Hardened Surfaces of Materials

open access: yesFractal and Fractional, 2023
A new method to determine a fractal network in chaotic systems is presented together with its application to the microstructure recognition of robot-laser-hardened (RLH) steels under various angles of a laser beam. The method is based on fractal geometry.

Diffusion-Reorganized Aggregates: Attractors in Diffusion Processes?

open access: yes, 2000
A process based on particle evaporation, diffusion and redeposition is applied iteratively to a two-dimensional object of arbitrary shape. The evolution spontaneously transforms the object morphology, converging to branched structures.

The Fractal Geometry of Critical Systems [PDF]

open access: yes, 2000
We investigate the geometry of a critical system undergoing a second order thermal phase transition. Using a local description for the dynamics characterizing the system at the critical point T=Tc, we reveal the formation of clusters with fractal ...

A Dual-Band Compact Metamaterial Absorber with Fractal Geometry

open access: yesElectronics, 2019
A fractal absorber based on a metamaterial configuration is proposed for dual-frequency operation within the UHF band. The miniaturization skills of the proposed fractal shape are used to design a dual-band metamaterial absorber cell with reduced size (

Fractal and geography: Fractal scanning in three different urban areas of Elazığ

open access: yesJournal of Design for Resilience in Architecture and Planning, 2023
The study of systems' ability to self-organize, internal structural balance, and space partitioning is the focus of a larger body of theories produced by mathematicians in the second half of the twenty-first century, which includes fractal theory and ...

Review article: methods of fractal geometry used in the study of complex geomorphic networks

open access: yesActa Universitatis Carolinae Geographica, 2014
Fractal geometry methods allow one to quantitatively describe self-similar or self-affined landscape shapes and facilitate the complex/holistic study of natural objects in various scales.

Theoretical Study of fractal shape material of negative refractive index [PDF]

open access: yesEngineering and Technology Journal, 2015
Advanced materials are artificial structure materials that exhibit properties not found in nature. Material that has a negative refractive index (left-handed materials) is found to get a lot of interest in the literatures.

Fractal-based algorithmic design of Chinese ice-ray lattices

open access: yesFrontiers of Architectural Research, 2022
Chinese ice-ray lattices are perhaps one of the earliest and controlled designs of asymmetric and complex patterns applied as a traditional motif in windows. Such intricate and complex designs developed centuries back have created an evident curiosity to

A fractal approach to the dark silicon problem: a comparison of 3D computer architectures -- standard slices versus fractal Menger sponge geometry

open access: yes, 2014
The dark silicon problem, which limits the power-growth of future computer generations, is interpreted as a heat energy transport problem when increasing the energy emitting surface area within a given volume. A comparison of two 3D-configuration models,
