Abstract: The structural characteristic is given by computerized tomography in non-destructive testing (NDT) of concrete. The position, size and style of inner defects can be shown. A Preconditioned ...
where \(f:R^n \rightarrow R\) is continuously differentiable. There are many methods for solving (1) such as quasi-Newton methods, Levenberg-Marquardt (LM) methods, and trust region methods. However, ...
To address the staircasing problem in deblurred images generated by a simple total variation (TV) based model, one approach is to use the total fractional-order variation (TFOV) image deblurring model ...
This repository contain the codes (written in C++) for the multigrid preconditioned BiConjugate Gradient Stabilized method (BICGSTAB) for variable-coefficient Poisson equations. Finite Difference ...
