Light Electric Vehicle zu entwickeln, das f{\"u}r den gewerblichen und den KEP-Einsatz geeignet ist. Das qualitativ hochwertige und zuverl{\"a}ssige neue Lastenfahrzeug soll das erfolgreiche Mikro-Depot-Konzept unterst{\"u}tzen und bereits vorhandene Lastenr{\"a}der ersetzen. Durch das neue Fahrzeug wird die Zustellung von Paketen und auch der Transport anderer G{\"u}ter verbessert werden. Im Teilprojekt „VALUE@SERVICE - Nachhaltige Logistische Mehrwertdienste f{\"u}r den station{\"a}ren Einzelhandel und f{\"u}r Apotheken durch kooperative Ressourcennutzung in logistischen Netzwerken" (07/2017-12/2019) wurde die Realisierungschance von logistischen Mehrwertdiensten durch gewerbliche Lastenradlogistik mit dem Mikro-Depot-Konzept gepr{\"u}ft. Das Projekt sollte das Mikro-Depot-Konzept um Same-Day-Delivery f{\"u}r den Einzelhandel und Apotheken, Next-Day-Delivery vom Einzelhandel zu {\"u}berregionalen Kunden und Retourenabwicklung im Onlinehandel erweitern. Ziel waren abgestimmte Nutzungskonzepte, mithilfe derer die Unternehmen DPD, Tiramizoo und Sanacorp zur optimalen Nutzung vorhandener Netzwerkressourcen. So sollte der Lieferverkehr durch getaktete Versandzeiten, gemeinsam genutzte Depots und zusammengelegte Auslieferungen effizienter werden. Um diese Anwendung zu realisieren, wurden die Gemeinsamkeiten und Unterschiede in den logistischen Anforderungen und Sendestrukturen gepr{\"u}ft.}, language = {de} } @inproceedings{GoetzelmannKreimeier2020, author = {G{\"o}tzelmann, Timo and Kreimeier, Julian}, title = {Optimization of navigation considerations of people with visual impairments through ambient intelligence}, publisher = {ACM}, address = {New York, NY, USA}, doi = {10.1145/3389189.3398009}, pages = {1 -- 6}, year = {2020}, abstract = {As urbanization progresses, cities are becoming increasingly complex. To make this complexity advantageous, Smart Cities integrate intelligent sensors that communicate with each other and are invisible to citizens, so that they can offer additional services. Despite the fact that the inclusion of diverse citizens is an essential requirement of Smart Cities, Ambient Intelligence is often not considered under accessibility aspects. The central question in this context is how disadvantaged groups in particular can benefit from Smart Cities. It is extremely important for people with disabilities to be able to move autonomously in public spaces. For this purpose, however, people who are blind sometimes need to be able to ask other people for directions. Knowing whether people are present can be important information. In our exemplary case study, Ambient Intelligence is used for people with visual impairments, so that they can decide whether they want to go to this or an alternative place based on the information about the density of people in a place.}, language = {en} } @inproceedings{SaurKruglovEngelbrecht2020, author = {Saur, Gregor and Kruglov, Roman and Engelbrecht, Rainer}, title = {Microsecond Optical Frequency Tuning of DFB Laser Diodes for Coherent Optical Frequency Domain Reflectometry}, volume = {2020}, publisher = {AMA Service GmbH}, address = {Wunstorf, Germany}, isbn = {978-3-9819376-2-6}, doi = {10.5162/SMSI2020/C6.2}, pages = {189 -- 190}, year = {2020}, abstract = {Optical frequency tuning ranges up to 600 GHz or 4.8 nm have been achieved within microseconds and a standard telecom DFB laser diode operating at 1550 nm.

The history of this concept is shown by tracing its development from a psychological, ecosystemic and socio-spatial perspective - focusing on spatial and social limitations of resilience. The current approach of social resilience derives from this background and emphases resilience as a dynamic process, embedded in social and institutional structures. Arising from this discussion, several elements of a new definition of social resilience are presented. Social resilience, especially within the context of poverty, is based on different sources, such as available common goods, reliable networks or civil society organisations. Our results show that the impact of social resilience is highly preconditioned, relates to different characteristics across our respondents and needs support of the welfare state and charity organisations to fully exploit its potential.}, language = {en} } @article{SowaRoesch2020, author = {Sowa, Frank and R{\"o}sch, Benedikt}, title = {Wohnungslose Menschen in Figurationen}, editor = {Oberbeck, Niels}, publisher = {Ohm}, address = {N{\"u}rnberg}, organization = {Technische Hochschule Georg Simon Ohm}, issn = {2626-7616}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:92-opus4-22505}, pages = {211 -- 218}, year = {2020}, abstract = {In einer Machbarkeitsstudie erforschte das Projektteam, inwiefern der Begriff der Figuration (Elias) geeignet ist, um bislang nicht ber{\"u}cksichtigte oder unentdeckte Aspekte des sozialen Ph{\"a}nomens Wohnungslosigkeit sichtbar zu machen und in f{\"u}r die Praxis anwendbare Erkenntnisse zu transformieren.

As a particularly specific, industry-oriented discipline, automotive software engineering is hardly represented in academic teaching, except for a few AUTOSAR courses. But as a beacon project of digitization, autonomous driving can arouse broad interest among students who are interested in how diverse disciplines can be profitably combined to realize an impressive project. This interest is an excellent chance for both universities and industry to engage in constructive dialogue, to carry out exciting multidisciplinary projects at universities and to meet the needs of industry with graduates who have a relevant and versatile education.

We study the problem of finding adversarial examples for such classifiers, i.e., to manipulate the images in such a way that they still look like the original images to a human but are misinterpreted by the classifier. Finding adversarial examples corresponds to a search problem in the image space. We focus on black-box attacks that can only use the original classifier to guide the search. The challenge is not to find adversarial examples, but rather to find them efficiently, ideally in real time. We show two novel methods that increase the efficiency of black-box search algorithms for adversarial examples: The first uses a relevance mask, i.e., a bitmask on the original image that restricts the search to those pixels that appear to be more relevant to the attacked classifier than others. The second exploits the discovery of merge drift, a phenomenon that negatively affects search algorithms that are based on the merging of image candidates. We evaluate both concepts on existing and new algorithms.}, language = {en} } @article{BiedermannReichPaschereit2020, author = {Biedermann, Till M. and Reich, M. and Paschereit, C.

Inspired by machine learning processes, the sampling of the experimental space is realized by use of a Latin hypercube design plus a factorial design, providing highly diverse information on the analyzed system. The effects of four influencing parameters (IP) are tested, characterizing the inflow conditions as well as the serration geometry. A total of 65 target values in the time and frequency domains are defined and can be approximated with high accuracy by individual artificial neural networks. Furthermore, the validation of the model against fully independent test points within the experimental space yields a remarkable fit, even for the spectral distribution in 1/3-octave bands, proving the ability of the model to generalize. A metaheuristic multi-objective optimization approach provides two-dimensional Pareto optimal solutions for selected pairs of target values. This is particularly important for reconciling opposing trends, such as the noise reduction capability and aerodynamic performance. The chosen optimization strategy also allows for a customized design of serrated leading edges, tailored to the specific operating conditions of the axial fan.}, language = {en} }
