Ternary-fractional differential transform schema: theory and application

Advances in Difference Equations, 2019
In this article, we propose a novel fractional generalization of the three-dimensional differential transform method, namely the ternary-fractional differential transform method, that extends its applicability to encompass initial value problems in the ...

A note on Hajłasz–Sobolev spaces on fractals

Journal of Mathematical Analysis and Applications, 2003
Let \(M \subset\mathbb{R}^n\) and let \(\mu\) be a Borel measure on \(M\). Then \(L_p (M,\mu)\) with \(1\leq p \leq \infty\) has the usual meaning. For \(\sigma >0\) the Hajłasz-Sobolev space \(H^\sigma_p (M,\mu)\) consists of all \(u \in L_p (M, \mu)\) such that \[ |u(x) - u(y)|\leq |x-y|^\sigma (v(x) + v(y)) \] for some \(v \in L_p (M, \mu ...

A Fixed‐Charge Interphase Synchronizes Ion Transport to Suppress Space‐Charge‐Driven Inefficiency Under Nanoliter Confinement

Angewandte Chemie International Edition, EarlyView.
Electrochemical energy storage breaks down under extreme miniaturization, where interfaces and space‐charge dominate device behavior. This work introduces a fixed‐charge selective interphase (FCSI) integrated into a twin‐tube micro‐Swiss‐roll architecture.

Radiative Hybrid Nanofluid Flow Over a Porous Riga Surface: A Fuzzy–ANN Modeling Approach

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This study proposes a fuzzy–ANN model to investigate the nonlinear thermal transport in a tangent hyperbolic (Tanh) hybrid nanofluid flow past a porous Riga surface, considering the effects of Rosseland diffusion, chemical reactions, and internal volumetric heating.

Is the drainage network a fractal Sierpinski space? [PDF]

Water Resources Research, 1997
The most common approach to extract the channel network from digital elevation models is to specify a threshold area, S, which is the minimum area required to drain to a point within which a channel forms. This threshold area is usually specified arbitrarily, although it is recognized that different threshold areas will result in substantially ...

Synergistic Effect on Enhanced Oil Recovery in High Salinity Carbonate Reservoirs Using a Novel PEI‐Functionalized Carbon Nanotube Nanocomposite

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Enhancing oil recovery (EOR) in mature reservoirs is hindered by high interfacial tension (IFT) and oil‐wet rock formations, especially under harsh, high‐salinity conditions. This study aims to overcome these limitations by synthesizing a novel carbon nanotube nanocomposite covalently grafted with polyethylenimine and non‐covalently ...

Stress sensitivity analysis of vuggy porous media based on two-scale fractal theory

Scientific Reports
Interparticle pore space and vugs are two different scales of pore space in vuggy porous media. Vuggy porous media widely exists in carbonate reservoirs, and the permeability of this porous media plays an important role in many engineering fields. It has
