Fast non-iterative methods for defect identification

Fast non-iterative methods for defect identification

This communication summarizes recent investigations on the identification of defects (cavities, inclusions) of unknown geometry and topology by means of the concept of topological sensitivity. This approach leads to the fast computation (equivalent to performing a few direct solutions), by means of ordinary numerical solution methods such as the BEM (used here), the FEM or the FDM, of defect in...

Iterative methods for solving non linear Fokker-Planck equation

Projected non-stationary simultaneous iterative methods

In this paper, we study Projected non-stationary Simultaneous It-erative Reconstruction Techniques (P-SIRT). Based on algorithmic op-erators, convergence result are adjusted with Opial’s Theorem. The advantages of P-SIRT are demonstrated on examples taken from to-mographic imaging.

Iterative Methods For Fast Radiosity Solutions

In applications involving the radiosity method such as computer animation, time is a crucial factor. This report shows that iterative methods which converge in a smaller number of iterations do not necessarily solve the radiosity system of linear equations in a faster way. For high average re ectance environments is introduced a method that converges faster than any standard method presented in...
