Stabilization of a Nonlinear Anaerobic Wastewater Treatment Model
Abstract. A nonlinear anaerobic digester model of wastewater treatment plants is considered. The stabilizability of the dynamic system is studied and a continuous stabilizing feedb...

Computational studies using a novel simplicial-approximation based algorithm for MINLP optimization
Significant advances have been made in the last two decades for the effective solution of mixed integer non-linear programming (MINLP) problems, mainly by exploiting the special s...

Sparsity-based Sinogram Denoising for low-dose Computed Tomography
We propose a sinogram restoration method which consists of a patch-wise non-linear processing, based on a sparsity prior in terms of a learned dictionary. An off-line learning pro...

Rational Krylov for Large Nonlinear Eigenproblems
Rational Krylov is an extension of the Lanczos or Arnoldi eigenvalue algorithm where several shifts (matrix factorizations) are used in one run. It corresponds to multipoint moment...
