Space-time error control using a partition-of-unity dual-weighted residual method applied to low mach number combustion
Jan Philipp Thiele, Thomas Wick
In this work, a space-time scheme for goal-oriented a posteriori error estimation is proposed. The error estimator is evaluated using a partition-of-unity dual-weighted residual me…
Multigoal-oriented dual-weighted-residual error estimation using deep neural networks
Ayan Chakraborty, Thomas Wick, Xiaoying Zhuang +1
Deep learning has shown successful application in visual recognition and certain artificial intelligence tasks. Deep learning is also considered as a powerful tool with high flexib…
SABMIS: Sparse approximation based blind multi-image steganography scheme
Rohit Agrawal, Kapil Ahuja, Marc C. Steinbach +1
We hide grayscale secret images into a grayscale cover image, which is considered to be a challenging steganography problem. Our goal is to develop a steganography scheme with enha…
Space-time formulation, discretization, and computations for phase-field fracture optimal control problems
Denis Khimin, Marc C. Steinbach, Thomas Wick
The purpose of this work is the development of space-time discretization schemes for phase-field optimal control problems. First, a time discretization of the forward problem is de…
Parallel domain decomposition solvers for the time harmonic Maxwell equations
Sven Beuchler, Sebastian Kinnewig, Thomas Wick
The time harmonic Maxwell equations are of current interest in computational science and applied mathematics with many applications in modern physics. In this work, we present para…
Adjoint-based methods for optimization and goal-oriented error control applied to fluid-structure interaction: implementation of a partition-of-unity dual-weighted residual estimator for stationary forward FSI problems in deal.II
Thomas Wick
In this work, we implement goal-oriented error control and spatial mesh adaptivity for stationary fluid-structure interaction. The a posteriori error estimator is realized using th…
