In order to contribute to active safety on the road, we propose in this work a low-cost Forward Collision Warning system that captures and processes images. Using cameras located in the rear section of a leading vehicle, this system serves the purpose of discouraging tailgating behavior from the vehicle driving behind. We perform in this paper the pertinent field tests to assess system performance, focusing on the calculated distance from the processing of images and the error margins in a straight line, as well as in a curve. Based on the evaluation results, the current version of the Tailigator can be used at speeds up to 50 km per hour without any restrictions. The measurements showed similar characteristics both on the straight line and in the curve. At close distances, between 3 and 5 m, the values deviated from the real value. At average distances, around 10 to 15 m, the Tailigator achieved the best results. From distances higher than 20 m, the deviations increased steadily with the distance. We contribute to the state of the art with an innovative low-cost system to identify tailgating behavior and raise awareness, which works independently of the rear vehicle's communication capabilities or equipment.}, subject = {tailgating}, language = {en} } @inproceedings{HimmelstossVotzi, author = {Himmelstoß, Felix and Votzi, Helmut}, title = {Four quadratic DC/DC converters with one low-side switch and a tapped inductor at the input side}, series = {Proceedings of IECON 2019, 45th Annual Conference of the IEEE Industrial Electronics Society, Lisbon, Portugal, Sep. 14-17, Lisbon Portugal}, booktitle = {Proceedings of IECON 2019, 45th Annual Conference of the IEEE Industrial Electronics Society, Lisbon, Portugal, Sep. 14-17, Lisbon Portugal}, pages = {1774 -- 1779}, subject = {DC/DC Converter}, language = {en} } @article{TeuschlHolnthonerMonforte, author = {Teuschl, Andreas and Holnthoner, Wolfgang and Monforte, Xavier}, title = {Repopulation of an auricular cartilage scaffold, AuriScaff, perforated with an enzyme combination}, series = {Acta Biomater.}, volume = {2019}, journal = {Acta Biomater.}, number = {Mar/86}, pages = {207 -- 222}, abstract = {Biomaterials currently in use for articular cartilage regeneration do not mimic the composition or architecture of hyaline cartilage, leading to the formation of repair tissue with inferior characteristics. In this study we demonstrate the use of "AuriScaff", an enzymatically perforated bovine auricular cartilage scaffold, as a novel biomaterial for repopulation with regenerative cells and for the formation of high-quality hyaline cartilage. AuriScaff features a traversing channel network, generated by selective depletion of elastic fibers, enabling uniform repopulation with therapeutic cells. The complex collagen type II matrix is left intact, as observed by immunohistochemistry, SEM and TEM. The compressive modulus is diminished, but three times higher than in the clinically used collagen type I/III scaffold that served as control. Seeding tests with human articular chondrocytes (hAC) alone and in co-culture with human adipose-derived stromal/stem cells (ASC) confirmed that the network enabled cell migration throughout the scaffold. It also guides collagen alignment along the channels and, due to the generally traverse channel alignment, newly deposited cartilage matrix corresponds with the orientation of collagen within articular cartilage. In an osteochondral plug model, AuriScaff filled the complete defect with compact collagen type II matrix and enabled chondrogenic differentiation inside the channels. Using adult articular chondrocytes from bovine origin (bAC), filling of even deep defects with high-quality hyaline-like cartilage was achieved after 6 weeks in vivo. With its composition and spatial organization, AuriScaff provides an optimal chondrogenic environment for therapeutic cells to treat cartilage defects and is expected to improve long-term outcome by channel-guided repopulation followed by matrix deposition and alignment. STATEMENT OF SIGNIFICANCE: After two decades of tissue engineering for cartilage regeneration, there is still no optimal strategy available to overcome problems such as inconsistent clinical outcome, early and late graft failures. Especially large defects are dependent on biomaterials and their scaffolding, guiding and protective function. Considering the currently used biomaterials, structure and mechanical properties appear to be insufficient to fulfill this task. The novel scaffold developed within this study is the first approach enabling the use of dense cartilage matrix, repopulate it via channels and provide the cells with a compact collagen type II environment. Due to its density, it also provides better mechanical properties than materials currently used in clinics. We therefore think, that the auricular cartilage scaffold (AuriScaff) has a high potential to improve future cartilage regeneration approaches.}, subject = {Auricular cartilage}, language = {en} } @inproceedings{WoeberTibihikaOlaverriMonrealetal., author = {W{\"o}ber, Wilfried and Tibihika, Papius D and Olaverri-Monreal, Cristina and Mehnen, Lars and Sykacek, Peter and Meimberg, Harald}, title = {Comparison of Unsupervised Learning Methods for Natural Image Processing}, series = {Biodiversity Information Science and Standards}, booktitle = {Biodiversity Information Science and Standards}, number = {3}, subject = {Machine Learning}, language = {en} } @inproceedings{HimmelstossJungmayer, author = {Himmelstoß, Felix and Jungmayer, Michael}, title = {Zero-Current-Switching Buck Converter}, series = {Proceedings of 2019 International Conference on Electrical Drives \& Power Electronics (EDPE), Novy Smokovec, Slovakia, 24-26 Sept. 2019}, booktitle = {Proceedings of 2019 International Conference on Electrical Drives \& Power Electronics (EDPE), Novy Smokovec, Slovakia, 24-26 Sept. 2019}, pages = {36 -- 41}, subject = {DC/DC Converter}, language = {en} } @article{NuernbergerSchneidervanOschetal., author = {N{\"u}rnberger, Sylvia and Schneider, Cornelia and van Osch, Gerjo and Keibl, Claudia and Rieder, Bernhard and Monforte, Xavier and Teuschl, Andreas and M{\"u}hleder, Severin and Holnthoner, Wolfgang and Sch{\"a}dl, Barbara and Gahleitner, Christoph and Redl, Heinz and Wolbank, Susanne}, title = {Repopulation of an auricular cartilage scaffold, AuriScaff, perforated with an enzyme combination.}, series = {Acta Biomaterialia}, journal = {Acta Biomaterialia}, subject = {Tissue Engineering}, language = {en} } @inproceedings{WoeberAburaiaOlaverriMonreal, author = {W{\"o}ber, Wilfried and Aburaia, Mohamed and Olaverri-Monreal, Cristina}, title = {Classification of Streetsigns Using Gaussian Process Latent Variable Models}, series = {2019 IEEE International Conference on Connected Vehicles and Expo (ICCVE), Graz, Austria}, booktitle = {2019 IEEE International Conference on Connected Vehicles and Expo (ICCVE), Graz, Austria}, subject = {Streetsigns}, language = {en} }
