Parameter optimization for low-rank matrix recovery in hyperspectral imaging
Monika Wolfmayr
An approach to parameter optimization for the low-rank matrix recovery method in hyperspectral imaging is discussed. We formulate an optimization problem with respect to the initia…
A posteriori error estimation for the optimal control of time-periodic eddy current problems
Monika Wolfmayr
This work presents the multiharmonic analysis and derivation of functional type a posteriori estimates of a distributed eddy current optimal control problem and its state equation…
Optimal heating of an indoor swimming pool
Monika Wolfmayr
This work presents the derivation of a model for the heating process of the air of a glass dome, where an indoor swimming pool is located in the bottom of the dome. The problem can…
Guaranteed lower bounds for cost functionals of time-periodic parabolic optimization problems
Monika Wolfmayr
In this paper, a new technique is shown for deriving computable, guaranteed lower bounds of functional type (minorants) for two different cost functionals subject to a parabolic ti…
A fast Fourier transform based direct solver for the Helmholtz problem
Jari Toivanen, Monika Wolfmayr
This paper is devoted to the efficient numerical solution of the Helmholtz equation in a two- or three-dimensional rectangular domain with an absorbing boundary condition (ABC). Th…
On the a posteriori error analysis for linear Fokker-Planck models in convection-dominated diffusion problems
Svetlana Matculevich, Monika Wolfmayr
This work is aimed at the derivation of reliable and efficient a posteriori error estimates for convection-dominated diffusion problems motivated by a linear Fokker-Planck problem…
Functional a posteriori error estimates for time-periodic parabolic optimal control problems
Ulrich Langer, Sergey Repin, Monika Wolfmayr
This paper is devoted to the a posteriori error analysis of multiharmonic finite element approximations to distributed optimal control problems with time-periodic state equations o…
A note on functional a posteriori estimates for elliptic optimal control problems
Monika Wolfmayr
In this work, new theoretical results on functional type a posteriori estimates for elliptic optimal control problems with control constraints are presented. More precisely, we der…
Functional a posteriori error estimates for parabolic time-periodic boundary value problems
Ulrich Langer, Sergey Repin, Monika Wolfmayr
The paper is concerned with parabolic time-periodic boundary value problems which are of theoretical interest and arise in different practical applications. The multiharmonic finit…
