A depth image is computed by calculating the distortion of a known infrared light (IR) pattern which is projected into the scene. While these sensors are great devices they have some limitations. The distance they can measure is limited and they suffer from reflection problems on transparent, shiny, or very matte and absorbing objects. If more than one RGB-D camera is used the IR patterns interfere with each other. This results in a massive loss of depth information. In this paper, we present a simple and powerful method to overcome these problems. We propose a stereo RGB-D camera system which uses the pros of RGB-D cameras and combine them with the pros of stereo camera systems. The idea is to utilize the IR images of each two sensors as a stereo pair to generate a depth map. The IR patterns emitted by IR projectors are exploited here to enhance the dense stereo matching even if the observed objects or surfaces are texture-less or transparent. The resulting disparity map is then fused with the depth map offered by the RGB-D sensor to fill the regions and the holes that appear because of interference, or due to transparent or reflective objects. Our results show that the density of depth information is increased especially for transparent, shiny or matte objects.}, language = {en} } @inproceedings{BungLangohrWaldenberger2023, author = {Bung, Daniel Bernhard and Langohr, Phillip and Waldenberger, Lisa}, title = {Influence of cycle number in CFD studies of labyrinth weirs}, series = {Proceedings of the 40th IAHR World Congress (Vienna, 2023)}, booktitle = {Proceedings of the 40th IAHR World Congress (Vienna, 2023)}, editor = {Habersack, Helmut and Tritthart, Michael}, publisher = {International Association for Hydro-Environment Engineering and Research (IAHR)}, address = {Madrid}, isbn = {978-90-833476-1-5}, issn = {L 2521-7119 (online)}, doi = {10.3850/978-90-833476-1-5_iahr40wc-p0531-cd}, year = {2023}, abstract = {The major advantage of labyrinth weirs over linear weirs is hydraulic efficiency. In hydraulic modeling efforts, this strength contrasts with limited pump capacity as well as limited computational power for CFD simulations. For the latter, reducing the number of investigated cycles can significantly reduce necessary computational time. In this study, a labyrinth weir with different cycle numbers was investigated. The simulations were conducted in FLOW-3D HYDRO as a Large Eddy Simulation. With a mean deviation of 1.75 \% between simulated discharge coefficients and literature design equations, a reasonable agreement was found. For downstream conditions, overall consistent results were observed as well. However, the orientation of labyrinth weirs with a single cycle should be chosen carefully under consideration of the individual research purpose.}, language = {en} } @article{ThielMufflerTippkoetteretal.2015, author = {Thiel, Alexander and Muffler, Kai and Tippk{\"o}tter, Nils and Suck, Kirstin and Sohling, Ulrich and Ruf, Friedrich and Ulber, Roland}, title = {Aufarbeitung von Polyphenolen aus Weizen mittels Zeolithen am Beispiel der Ferulas{\"a}ure}, series = {Chemie IngenieurTechnik}, volume = {87}, journal = {Chemie IngenieurTechnik}, number = {1-2}, publisher = {Wiley}, address = {Weinheim}, doi = {10.1002/cite.201400031}, pages = {128 -- 136}, year = {2015}, abstract = {Aufarbeitung von Polyphenolen aus Weizenmittels Zeolithen am Beispiel der Ferulasa¨ ureAlexander Thiel1, Kai Muffler1, Nils Tippko¨ tter1, Kirstin Suck2, Ulrich Sohling2, Friedrich Ruf3und Roland Ulber1,*DOI: 10.1002/cite.201400031Bei der Ferulasa¨ure handelt es sich um einen Wertstoff, der aus Weizen gewonnen und in der Lebensmittel- und Pharma-industrie eingesetzt werden kann.
