Numerical Solution of Some Types of Fractional Optimal Control Problems

Autor: Nasser Hassan Sweilam, Tamer Mostafa Al-Ajami, Ronald H. W. Hoppe

Publikováno v: The Scientific World Journal, Vol 2013 (2013)

We present two different approaches for the numerical solution of fractional optimal control problems (FOCPs) based on a spectral method using Chebyshev polynomials. The fractional derivative is described in the Caputo sense. The first approach follo

Numerical simulation of the formation of spherulites in polycrystalline binary mixtures

Autor: Basanta R. Pahari, James J. Winkle, Ronald H. W. Hoppe

Publikováno v: Applied Numerical Mathematics. 166:61-75

Spherulites are growth patterns of average spherical form which may occur in the polycrystallization of binary mixtures due to misoriented angles at low grain boundaries. The dynamic growth of spherulites can be described by a phase field model where

An equilibrated a posteriori error estimator for an Interior Penalty Discontinuous Galerkin approximation of the p-Laplace problem

Autor: Ronald H. W. Hoppe, Youri Iliash

We are concerned with an Interior Penalty Discontinuous Galerkin (IPDG) approximation of the p-Laplace equation and an equilibrated a posteriori error estimator. The IPDG method can be derived from a discretization of the associated minimization prob

Efficient numerical solution of mixed finite element discretizations by adaptive multilevel methods

Autor: Barbara Wohlmuth, Ronald H. W. Hoppe

We consider mixed finite element discretizations of second order elliptic boundary value problems. Emphasis is on the efficient iterative solution by multilevel techniques with respect to an adaptively generated hierarchy of nonuniform triangulations

A C0 interior penalty discontinuous Galerkin method for fourth‐order total variation flow I: Derivation of the method and numerical results

Autor: Chandi Bhandari, Rajesh Kumar, Ronald H. W. Hoppe

Publikováno v: BIRD: BCAM's Institutional Repository Data

We consider the numerical solution of a fourth‐order total variation flow problem representing surface relaxation below the roughening temperature. Based on a regularization and scaling of the nonlinear fourth‐order parabolic equation, we perform

C $$^0$$ -Interior Penalty Discontinuous Galerkin Approximation of a Sixth-Order Cahn-Hilliard Equation Modeling Microemulsification Processes

Autor: Christopher Linsenmann, Ronald H. W. Hoppe

Publikováno v: Computational Methods in Applied Sciences ISBN: 9783319783246

Microemulsions can be modeled by an initial-boundary value problem for a sixth order Cahn-Hilliard equation. Introducing the chemical potential as a dual variable, a Ciarlet-Raviart type mixed formulation yields a system consisting of a linear second
