Joint denoising and line distortion correction for raster-scanned image series
Benjamin Berkels, Peter Binev
The problem of noise in a general data acquisition procedure can be resolved more accurately if it is based on a model that describes well the distortions of the data including bot…
On the importance of the -regularization of the distribution-dependent Mumford-Shah model for hyperspectral image segmentation
Jan-Christopher Cohrs, Benjamin Berkels
Recently, the distribution-dependent Mumford-Shah model for hyperspectral image segmentation was introduced. It approximates an image based on first and second order statistics usi…
A fast food-freezing temperature estimation framework using optimally located sensors
Felipe Galarce, Diego Rivera, Douglas Pacheco +2
This article presents and assesses a framework for estimating temperature fields in real time for food-freezing applications, significantly reducing computational load while ensuri…
An Asymptotic-Preserving Scheme for Isentropic Flow in Pipe Networks
Michael Redle, Michael Herty
We consider the simulation of isentropic flow in pipelines and pipe networks. Standard operating conditions in pipe networks suggest an emphasis to simulate low Mach and high frict…
Secure numerical simulations using fully homomorphic encryption
Arseniy Kholod, Yuriy Polyakov, Michael Schlottke-Lakemper
Data privacy is a significant concern when using numerical simulations for sensitive information such as medical, financial, or engineering data -- especially in untrusted environm…
An adaptive space-time method for nonlinear poroviscoelastic flows with discontinuous porosities
Markus Bachmayr, Simon Boisserée
This paper is concerned with a space-time adaptive numerical method for instationary porous media flows with nonlinear interaction between porosity and pressure, with focus on prob…
