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.
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.

This review article summarizes the state of the art in energy efficiency (EE) management in air and rail cargo transportation. After an introduction, explanations and definitions follow around the topic of energy efficiency. The political framework conditions of the European Union (EU) as well as the associated European Union Emissions Trading System are described. In particular, the drive technologies, CO2 emissions, and fuel-saving options are reviewed.

Cyberphysical production systems are an important part of today’s manufacturing process. The ever-growing need of highly optimized,
i.e. at the same time flexible and ecient systems, requires the use of not only appropriate machines, but as well a
communication framework and data model that is manufacturer independent and scalable. This paper proposes a communicationframework
based on OPC UA that employs an agent-based architecture. The proposed system has been implemented and tested in
the Digital Factory of the UAS Technikum Wien. It shows promising behavior within distributed manufacturing systems.
