A Mixed Method for the Biharmonic Problem Based On a System of First-Order Equations
We introduce a new mixed method for the biharmonic problem. The method is based on a formulation where the biharmonic problem is re-written as a system of four first-order equatio...

Time domain model order reduction by wavelet collocation method
In this paper, a wavelet based approach is proposed for the model order reduction of linear circuits in time domain. Compared with Chebyshev reduction method, the wavelet reductio...

Finite Element-Based Level Set Methods for Higher Order Flows
In this paper we shall discuss the numerical simulation of higher order geometric flows by level set methods. Main examples under considerations are surface diffusion and the Will...

A Second Order Adjoint Method to Targeted Observations
The role of the second order adjoint in targeting strategies is studied and analyzed. Most targeting strategies use the first order adjoint to identify regions where additional in...

On a high order numerical method for functions with singularities
By splitting a given singular function into a relatively smooth part and a specially structured singular part, it is shown how the traditional Fourier method can be modified to gi...
