Codes as Fractals and Noncommutative Spaces [PDF]

open access: yesMathematics in Computer Science, 2012
We consider the CSS algorithm relating self-orthogonal classical linear codes to q-ary quantum stabilizer codes and we show that to such a pair of a classical and a quantum code one can associate geometric spaces constructed using methods from noncommutative geometry, arising from rational noncommutative tori and finite abelian group actions on Cuntz ...

Fractal Characteristic Analysis of Urban Land-Cover Spatial Patterns with Spatiotemporal Remote Sensing Images in Shenzhen City (1988–2015)

open access: yesRemote Sensing, 2021
Understanding the urban land-cover spatial patterns is of particular significance for sustainable development planning. Due to the nonlinear characteristics related to the spatial pattern for land cover, it is essential to provide a new analysis method ...

Fractalization of Fractional Integral and Composition of Fractal Splines

open access: yesChaos Theory and Applications, 2023
The present study perturbs the fractional integral of a continuous function $f$ defined on a real compact interval, say $(\mathcal{I}^vf)$ using a family of fractal functions $(\mathcal{I}^vf)^\alpha$ based on the scaling parameter $\alpha$.

Recycled Dystopias: Cyberpunk and the End of History

open access: yesArts, 2018
While cyberpunk is often described as a dystopian genre, the paper argues that it should be seen rather as a post-utopian one. The crucial difference between the two resides in the nature of the historical imagination reflected in their respective ...

He’s frequency formula to fractal undamped Duffing equation

open access: yesJournal of Low Frequency Noise, Vibration and Active Control, 2021
Nonlinear oscillation is an increasingly important and extremely interesting topic in engineering. This article completely reviews a simple method proposed by Ji-Huan He and successfully establishes a fractal undamped Duffing equation through the two ...

Multi Fractals of Generalized Multivalued Iterated Function Systems in b-Metric Spaces with Applications

open access: yesMathematics, 2019
In this paper, we obtain multifractals (attractors) in the framework of Hausdorff b-metric spaces. Fractals and multifractals are defined to be the fixed points of associated fractal operators, which are known as attractors in the literature of fractals.

Constructing a Linearly Ordered Topological Space from a Fractal Structure: A Probabilistic Approach

open access: yesMathematics, 2022
Recent studies have shown that it is possible to construct a probability measure from a fractal structure defined on a space. On the other hand, a theory on cumulative distribution functions from an order on a separable linearly ordered topological space

Estimating the Permeability of Carbonate Rocks from the Fractal Properties of Moldic Pores using the Kozeny-Carman Equation [PDF]

open access: yesResearch Ideas and Outcomes, 2018
Reservoir modeling of carbonate rocks requires a proper understanding of the pore space distribution and its relationship to permeability. Using a pigeonhole fractal model we characterize the fractal geometry of moldic pore spaces and extract the fractal
