(author), Denk, Martin (author), Göddeke, Dominik (author), Powalla, Michael (author)Abstract: We show that the concept of topology optimization for metallization grid patterns of thin-film solar devices can be applied to monolithically integrated solar cells. Different irradiation intensities favor different topological grid designs as well as a different thickness of the transparent conductive oxide (TCO) layer. For...journal article 2022

Weymouth, Gabriel D. (author)Pressure projection is the single most computationally expensive step in an unsteady incompressible fluid simulation. This work demonstrates the ability of data-driven methods to accelerate the approximate solution of the Poisson equation at the heart of pressure projection. Geometric Multi-Grid methods are identified as linear convolutional...journal article 2022

Seis, W.A.A. (author), Rouault, Pascale (author), Miehe, Ulf (author), ten Veldhuis, Marie-claire (author), Medema, G.J. (author)Norovirus infections are among the major causes of acute gastroenteritis worldwide. In Germany, norovirus infections are the most frequently reported cause of gastroenteritis, although only laboratory confirmed cases are officially counted. The high infectivity and environmental persistence of norovirus, makes the virus a relevant pathogen...journal article 2022

Vermunt, P.C. (author), Steele-Dunne, S.C. (author), Khabbazan, S. (author), Kumar, V. (author), Judge, Jasmeet (author)For a good interpretation of radar backscatter sensitivity to vegetation water dynamics, we need to know which parts of the vegetation layer control that backscatter. However, backscatter sensitivity to different depths in the canopy is poorly understood. This is partly caused by a lack of observational data to describe the vertical moisture...journal article 2022
