Designing experiments which delocalize ever more complex and more massive particles requires a quantitative assessment of new interferometer configurations. Here, we introduce a figure of
merit which quantifies the difference between a genuine quantum interference pattern and a classical shadow and use it to compare a number of near-field interferometer schemes. This allows us to identify the most promising setups for future tests of the quantum superposition principle, and to discuss the perspectives of interferometry with complex molecules and clusters.
Changes of particle deposition caused by different breathing patterns during active lung simulation
(2019)
Simulation models in respiratory research are increasingly used for medical product development and testing, especially because in-vivo models are coupled with a high degree of complexity and ethical concerns. 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.
Der Einsatz von Lernvideos ist aus zeitgemäßer Lehre kaum noch wegzudenken. Um adäquates, fachlich und didaktisch abgestimmtes Lehr-und Lernmaterial mit angemessenem Ressourcenaufwand zu ermöglichen, ist es für Hochschulen und fachliche ExpertInnen ein sinnvoller Weg, selbst Lehrvideos zu produzieren. Dieser Beitrag stellt ein Beispiel guter Praxis im Aufbau und Betrieb eines E-Learning Labors vor. Dabei werden die Infrastruktur und Technik, das Produktions-Prozedere sowie mediendidaktische und rechtliche Aspekte beleuchtet.
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.

Mutual Benefits from Entrepreneurship of Non-business University Graduates for Academia and Founders
(2019)
There is a trend among universities to teach entrepreneurship and support startup initiatives. In this article, the state-ofthe-
art in entrepreneurship higher education and university ecosystems of non-business schools is reviewed, and the example of the University of Applied Sciences Technikum Wien, Austria, and one of its startup show cases, Toolsense, is elaborated to understand critical success factors for non-business graduates as founders. The mutual benefits for universities and founders are discussed. In the case of Toolsense and the University of Applied Sciences, narrow band IoT as brought to the University by the startup. Implications on a universities’ innovation and portfolio management are highlighted. Concerning startups, the importance of growth financing after initial success is elaborated.
