Numerical and artificial neural network prediction of double-stratified magnetized nanofluid flow and heat transfer over a stretchable cylinder with Brownian motion and thermal slip [PDF]

open access: yesDiscover Nano
The current study aims to investigate the effects of double stratification on magneto-hydrodynamic (MHD) nanofluid flow over a stretching cylinder in the presence of thermal radiation. The model incorporates Brownian motion, thermophoresis, and velocity,

On fixed point index theory for the sum of operators and applications to a class of ODEs and PDEs

open access: yesApplied General Topology, 2021
The aim of this work is two fold: first  we  extend some results concerning the computation of the fixed point index for the sum of an expansive mapping and a $k$-set contraction  obtained in \cite{DjebaMeb, Svet-Meb}, to  the case of the sum $T+F ...

A New Numerical Scheme for Time Fractional Diffusive SEAIR Model with Non-Linear Incidence Rate: An Application to Computational Biology

open access: yesFractal and Fractional, 2022
In this paper, we propose a modified fractional diffusive SEAIR epidemic model with a nonlinear incidence rate. A constructed model of fractional partial differential equations (PDEs) is more general than the corresponding model of fractional ordinary ...

Minimal positive solutions for systems of semilinear elliptic equations

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2017
The paper is devoted to a system of nonlinear PDEs containing gradient terms. Applying the approach based on Sattinger's iteration procedure we use sub and supersolutions methods to prove the existence of positive solutions with minimal growth.

Comparative Assessment of Nonlocal Continuum Solvent Models Exhibiting Overscreening

open access: yesComputational and Mathematical Biophysics, 2017
Nonlocal continua have been proposed to offer a more realistic model for the electrostatic response of solutions such as the electrolyte solvents prominent in biology and electrochemistry. In this work, we review three nonlocal models based on the Landau-

Variational approach for the n-dimensional stationary Navier-Stokes equations with a damping term

open access: yesElectronic Journal of Differential Equations
We study the \(n\)-dimensional stationary Navier-Stokes equations with a damping term by developing a new general minimax principle. This principle is sufficiently broad to be applied in various contexts, and here it is used to establish the existence ...
