The Fourier spectral method for the Cahn-Hilliard equation
In this paper, a Fourier spectral method for numerically solving Cahn-Hilliard equation with periodic boundary conditions is developed. We establish their semi-discrete and fully d...

Symbolic computing of nonlinear observable and observer forms
Observer design for highly nonlinear dynamics is an important issue, particularly when the locally observable dynamics are not linearly observable. In such circumstances the abili...

Axisymmetric finite element solution of non-isothermal parallel-plate flow
Steady non-isothermal parallel-plate flow of a Newtonian fluid with a temperature dependent viscosity is considered. The viscosity is modelled by a Nahme type law. We apply axisym...
