New Approach to Fractal Approximation of Vector-Functions

Abstract and Applied Analysis, 2015
This paper introduces new approach to approximation of continuous vector-functions and vector sequences by fractal interpolation vector-functions which are multidimensional generalization of fractal interpolation functions.

Adaptive Interpolation Scheme for Image Magnification Based on Local Fractal Analysis

IEEE Access, 2020
In this paper, we constructed a new rational fractal interpolation model with scale factors and shape parameters. The model obtains different expressions by changing the scale factor, according with the diversity of image features.

Positivity-Preserving Rational Cubic Fractal Interpolation Function Together with Its Zipper Form

Axioms
In this paper, a novel class of rational cubic fractal interpolation function (RCFIF) has been proposed, which is characterized by one shape parameter and a linear denominator.

Study on the propagation velocity of methane/air pleated flames based on image processing and fractal interpolation

AIP Advances, 2021
A self-developed gas explosion experimental system was used to detonate methane/air mixtures of different concentrations by different ignition methods, and the propagation processes of spherical flames and irregular flames formed by the explosions were ...

Fractal Dimension of Fractal Functions on the Real Projective Plane

Fractal and Fractional, 2023
In this article, we consider an iterated functions system on the non-Euclidean real projective plane which has a linear structure. Then, we study the fractal dimension of the associated curve as a subset of the projective space and like a set of the ...

Spatial Distribution of Multi-Fractal Scaling Behaviours of Atmospheric XCO₂ Concentration Time Series during 2010–2018 over China

Entropy, 2022
Exploring the spatial distribution of the multi-fractal scaling behaviours in atmospheric CO2 concentration time series is useful for understanding the dynamic mechanisms of carbon emission and absorption.

Life‐Like Ferrous Oxide Microspheres from Kombucha

Advanced Materials Interfaces, EarlyView.
Kombucha bacterial cellulose, sodium alginate, and ferrous nitrate self‐assemble into membrane‐enclosed iron oxide microspheres. These microspheres bud daughter vesicles, sustain 24‐h electrochemical oscillations, and filter theta‐band signals.

Flame Suppression in Lithium‐Ion Batteries During Thermal Runaway Through Solvent Design Considering the Volatility–Flammability Relationship

Advanced Science, EarlyView.
An asymmetric sulfonate solvent forms thermally stable interphases and demonstrates non‐flammability, suppressing heat accumulation for safer, high‐performance lithium‐ion batteries. ABSTRACT An asymmetric sulfonate‐based linear solvent, 2,2,2‐trifluoromethyl mesylate (FMS), is designed and used as the primary solvent in liquid electrolytes to enhance ...

Parameter Identification of Bivariate Fractal Interpolation Surfaces by Using Convex Hulls

Mathematics, 2023
The scope of this article is to identify the parameters of bivariate fractal interpolation surfaces by using convex hulls as bounding volumes of appropriately chosen data points so that the resulting fractal (graph of) function provides a closer fit ...
