A Truly Second-Order and Unconditionally Stable Thermal Lattice Boltzmann Method

open access: yesApplied Sciences, 2017
An unconditionally stable thermal lattice Boltzmann method (USTLBM) is proposed in this paper for simulating incompressible thermal flows. In USTLBM, solutions to the macroscopic governing equations that are recovered from lattice Boltzmann equation (LBE)

An unconditionally stable finite-difference method for the solution of multi-dimensional transport equation

open access: yesAin Shams Engineering Journal, 2021
The rightward representation of the Barakat-Clark ADE scheme is extended for the solution of the Multi-dimensional Transport equation. The first-order derivative of the Transport equation is represented by a one-sided multi-level finite-difference.

Unconditionally Stable Shock Filters for Image and Geometry Processing [PDF]

open access: yesComputer Graphics Forum, 2015
AbstractThis work revisits the Shock Filters of Osher and Rudin [OR90] and shows how the proposed filtering process can be interpreted as the advection of image values along flow‐lines. Using this interpretation, we obtain an efficient implementation that only requires tracing flow‐lines and re‐sampling the image.

Unconditionally stable high-order scheme for the fractional generalized Burgers-Huxley equation [PDF]

open access: yesIranian Journal of Numerical Analysis and Optimization
This study presents a high-order numerical scheme for solving the generalized fractional-order Burgers-Huxley equation, a nonlinear evolutionary PDE combining integer-order spatial derivatives with temporal fractional derivatives.

An Unconditionally Stable Parallel Difference Scheme for Telegraph Equation [PDF]

open access: yesMathematical Problems in Engineering, 2009
We use an unconditionally stable parallel difference scheme to solve telegraph equation. This method is based on domain decomposition concept and using asymmetric Saul′yev schemes for internal nodes of each sub‐domain and alternating group implicit method for sub‐domain′s interfacial nodes.

Unconditionally Stable Difference Scheme for the Numerical Solution of Nonlinear Rosenau-KdV Equation [PDF]

open access: yesMathematics Interdisciplinary Research, 2016
In this paper we investigate a nonlinear evolution model described by the Rosenau-KdV equation. We propose a three-level average implicit finite difference scheme for its numerical solutions and prove that this scheme is stable and convergent in the ...

High-order generalized-alpha method

open access: yesApplications in Engineering Science, 2020
The generalized-α method encompasses a wide range of time integrators. The method possesses high-frequency dissipation while minimizing unwanted low-frequency dissipation. Additionally, the numerical dissipation can be controlled by the user by setting a

On the Lower Bound to the Input and Output Mismatch of Conditionally Stable Linear Two-Ports

open access: yesIEEE Journal of Microwaves, 2023
In the design of amplifier stages based on unconditionally stable linear active two-ports, the amplifier gain can be maximized through simultaneous conjugate matching with passive loads at the input and output ports.
