On the numerical solution of the diffusion equation with a nonlocal boundary condition

open access: yesMathematical Problems in Engineering, Volume 2003, Issue 2, Page 81-92, 2003., 2003
Parabolic partial differential equations with nonlocal boundary specifications feature in the mathematical modeling of many phenomena. In this paper, numerical schemes are developed for obtaining approximate solutions to the initial boundary value problem for one‐dimensional diffusion equation with a nonlocal constraint in place of one of the standard ...

A Macroscopic Continuum Framework for Urban Traffic With Dynamic Curbside Parking Activity

open access: yesJournal of Advanced Transportation, Volume 2026, Issue 1, 2026.
Urban traffic performance is strongly shaped by interactions between moving vehicles and curbside activities such as parking maneuvers, deliveries, and ride‐hailing pickups. These interactions modify effective capacity and driver behavior in ways not captured by conventional macroscopic traffic models. This study introduces the macroscopic activity and

Fast implicit schemes for the fokker-planck-landau equation [PDF]

open access: yes, 2004
We propose time implicit schemes to solve the homogeneous Fokker-Planck-Landau equation in both the isotropic and 3D geometries. These schemes have properties of conservation and entropy. Moreover, they allow for large time steps, making them faster than

A SPECTRAL METHOD FOR PANTOGRAPH-TYPE DELAY DIFFERENTIAL EQUATIONS AND ITS CONVERGENCE ANALYSIS [PDF]

open access: yes, 2009
We propose a novel numerical approach for delay differential equations with vanishing proportional delays based on spectral methods. A Legendre-collocation method is employed to obtain highly accurate numerical approximations to the exact solution. It is

A Conservative Difference Scheme for Space Fractional Klein-Gordon-Schrödinger Equations with a High-Degree Yukawa Interaction

open access: yesEast Asian Journal on Applied Mathematics, 2018
A conservative finite difference scheme for nonlinear space fractional KleinGordon-Schrödinger systems with high-degree Yukawa interaction is studied. We show that the arising difference equations are uniquely solvable and approximate solutions converge ...

Artificial Intelligence–Assisted Fractional Nonstandard Finite Difference Scheme for a Noncommensurate Quarantine Reaction–Diffusion Epidemic Model

open access: yesInternational Journal of Differential Equations, Volume 2026, Issue 1, 2026.
This paper develops a noncommensurate time‐fractional SEIQR reaction–diffusion model for infectious disease dynamics with artificial intelligence (AI)–assisted inverse identification and forecasting. The susceptible, exposed, infected, quarantined, and recovered classes are governed by distinct Caputo fractional orders so that latency, infection ...

Hybrid Fitted Numerical Scheme for Singularly Perturbed Spatiotemporal Delay Differential Equations

open access: yesInternational Journal of Differential Equations, Volume 2026, Issue 1, 2026.
In this study, a hybrid scheme is presented to solve a singularly perturbed time‐delay differential equation with a delay and advance term in the spatial variable. The scheme combines the midpoint upwind scheme and the cubic spline difference scheme in the outer and inner layer regions, respectively, on a nonuniform mesh for the spatial discretization,

A second order finite difference scheme for singularly perturbed Volterra integro-differential equation

open access: yesAlexandria Engineering Journal, 2020
In this paper, a singularly perturbed Volterra integro-differential equation, characterised by a single layer, is investigated. A numerical technique which uses a non-standard finite difference scheme is implemented to solve the differential part ...
