In this paper, a robust surface intersection algorithm is constructed using interval arithmetic and annealing genetic algorithm. By using interval arithmetic to analyse error boundary, to divide three ill-conditioned cases in surface intersection, and improve the robustness of the algorithm. By utilizing the global s...

It is posed in paper [1] that Zero energy-error can be used to realize the optimization of Combined hybrid finite element methods through adjusting the combined factor. In this paper, the optimization method is used to plane 4-node quadrilateral Combined hybrid scheme CH(0-1) which own 5 stress parameters with energy...

Cointegration analysis for time series involves the solution of a generalized eigenproblem involving moment matrices and inverted moment matrices. These formulae are unsuitable for actual computations because the condition numbers of the resulting matrices are unnecessarily increased. The special structure of the coi...

A pressure weighted method is proposed for numerical solution of the momentum equation in 2D Lagrangian hydrodynamic equations with heat conduction over quadrilateral mesh. It is equivalent to the usual circuit integral method when the mesh is regular. However, when the mesh deforms, it has some advantages over the c...

For the problems exiting in real seismic data processing, such as S/N ratio and resolution, this paper utilizes 2D wavelet transform and multi-resolution analysis to attenuate noise and enhance resolution. Many calculations preseuted in this paper have shown that the data quality after multi-resolution analysising is...

In this paper, we propose a fast algorithm for computing the Discrete Generalized Fourier Transforms on parallel dodecahedron domains with 3 dimensions and 4 directions. Our fast algorithm (HFFT) reduces the computation complexity of DGFT from O(N^6) to O(N^3log N). A parallel implementation is given and it has been ...

Recursion leads to automatic matrix blocking in the computation of dense linear algebra. It makes a good use of memory hierarchies of today's high-performance computers and hence improves the efficiency of the algorithm. The recursive algorithm for LU factorization of matrix that is used to solve linear systems of eq...
