This work introduces a respiratory simulation system, which is bridging the gap between the complex, real anatomical environment and the safe, cost-effective simulation methods. The presented electro-mechanical lung simulator, xPULM, combines in-silico, ex-vivo and mechanical respiratory approaches by realistically replicating an actively breathing human lung. The reproducibility of sinusoidal breathing simulations with xPULM was verified for selected breathing frequencies (10-18 bpm) and tidal volumes (400-600 ml) physiologically occurring during human breathing at rest. Human lung anatomy was modelled using latex bags and primed porcine lungs. High reproducibility of flow and pressure characteristics was shown by evaluating breathing cycles (nTotal = 3273) with highest standard deviation |3σ| for both, simplified lung equivalents (μV˙ = 23.98 ± 1.04 l/min, μP = -0.78 ± 0.63 hPa) and primed porcine lungs (μV˙ = 18.87 ± 2.49 l/min, μP = -21.13 ± 1.47 hPa). The adaptability of the breathing simulation parameters, coupled with the use of porcine lungs salvaged from a slaughterhouse process, represents an advancement towards anatomically and physiologically realistic modelling of human respiration.}, subject = {Breathing Simulation}, language = {en} } @misc{Pasteka, author = {Pasteka, Richard}, title = {International Week Turku, "Hands-on learning and research applications"}, subject = {Biomedical Engineering}, language = {en} } @article{Lietze, author = {Lietze, Stefanie}, title = {Teamteaching, Fehler- und Feedbackkultur}, volume = {2019}, number = {01/2019}, editor = {f{\"u}r LehrerInnenbildung, Journal}, pages = {90 -- 96}, subject = {Teaching}, language = {de} } @misc{Pasteka, author = {Pasteka, Richard}, title = {Applications of Biomedical Engineering in Respiratory Care}, subject = {Biomedical Engineering}, language = {en} } @inproceedings{PastekaForjan, author = {Pasteka, Richard and Forjan, Mathias}, title = {Changes of particle deposition caused by different breathing patterns during active lung simulation}, series = {41st Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2019}, booktitle = {41st Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2019}, organization = {IEEE}, pages = {4969 -- 4972}, subject = {Lung Simulation}, language = {en} } @article{KrizekHausleitnerBoehmeetal., author = {Krizek, Gerd Christian and Hausleitner, Rene and B{\"o}hme, Laura and Olaverri-Monreal, Cristina}, title = {Empirical Analysis of Safe Distance Calculation by the Stereoscopic Capturing and Processing of Images Through the Tailigator System}, series = {sensors}, journal = {sensors}, abstract = {Driver disregard for the minimum safety distance increases the probability of rear-end collisions. 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} }
