A B-spline finite element method for solving a class of nonlinear parabolic equations modeling epitaxial thin-film growth with variable coefficient

open access: yesAdvances in Difference Equations, 2020
In this paper, we propose an efficient B-spline finite element method for a class of fourth order nonlinear differential equations with variable coefficient. For the temporal discretization, we choose the Crank–Nicolson scheme.

Semi-discrete Schemes for Hamilton-Jacobi Equations on Unstructured Grids [PDF]

open access: yes, 2004
We present a new semi-discrete central scheme for approximating solutions of Hamilton-Jacobi equations on unstructured meshes. This scheme extends the numerical Hamiltonians of Kurganov et al. to unstructured grids. Similarly to the previous works on structured grids, a semi-discrete formulation of central schemes is made possible due to estimates of ...

Analysis of the modified mass method for the dynamic Signorini problem with Coulomb friction [PDF]

open access: yes, 2011
International audienceThe aim of the present work is to analyze the modified mass method for the dynamic Signorini problem with Coulomb friction. We prove that the space semi-discrete problem is equivalent to an upper semi-continuous one-sided Lipschitz ...

Classification of phase transitions of finite Bose-Einstein condensates in power law traps by Fisher zeros [PDF]

open access: yes, 2001
We present a detailed description of a classification scheme for phase transitions in finite systems based on the distribution of Fisher zeros of the canonical partition function in the complex temperature plane.

Mean almost periodicity and moment exponential stability of semi-discrete random cellular neural networks with fuzzy operations.

open access: yesPLoS ONE, 2019
By using the semi-discretization technique of differential equations, the discrete analogue of a kind of cellular neural networks with stochastic perturbations and fuzzy operations is formulated, which gives a more accurate characterization for ...

Convergence analysis for a stabilized linear semi-implicit numerical scheme for the nonlocal Cahn-Hilliard equation [PDF]

open access: yesMathematics of Computation, 2019
In this paper, we provide a detailed convergence analysis for a first order stabilized linear semi-implicit numerical scheme for the nonlocal Cahn–Hilliard equation, which follows from consistency and stability estimates for the numerical error function.

Fully discrete WENO with double entropy condition for hyperbolic conservation laws

open access: yesEngineering Applications of Computational Fluid Mechanics, 2023
This paper put forward a new fully discrete scheme construction method – double entropy condition solution formula method. With that, we turn the state-of-the-art semi-discrete WENO + RK scheme into a fully discrete scheme, which is named as Full-WENO. A
