TY - RPRT A1 - Bogdanski, Ralf T1 - Vorläufiger Abschlussbericht der Forschungsprojekte LEV@KEP & VALUE@SERVICE N2 - Ziel des Projekts „LEV@KEP – Entwicklung eines zulassungsfreien Light Electric Vehicle für eine Nachhaltige Stadtlogistik“ (07/2017 bis 12/2019)“ war es, ein Schwerlastenrad bzw. Light Electric Vehicle zu entwickeln, das für den gewerblichen und den KEP-Einsatz geeignet ist. Das qualitativ hochwertige und zuverlässige neue Lastenfahrzeug soll das erfolgreiche Mikro-Depot-Konzept unterstützen und bereits vorhandene Lastenräder ersetzen. Durch das neue Fahrzeug wird die Zustellung von Paketen und auch der Transport anderer Güter verbessert werden. Im Teilprojekt „VALUE@SERVICE – Nachhaltige Logistische Mehrwertdienste für den stationären Einzelhandel und für 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 geprüft. Das Projekt sollte das Mikro-Depot-Konzept um Same-Day-Delivery für den Einzelhandel und Apotheken, Next-Day-Delivery vom Einzelhandel zu überregionalen 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 geprüft.

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.

The dynamic optical frequency tuning is induced by electrical current pulse injection and measured using an interferometric setup. Potentially, low-cost sensor systems based on optical coherence tomography (OCT) or coherent optical frequency domain reflectometry (c-OFDR) could be realized, achieving sub-mm two-point range resolution or even better single-point range precision within a few microseconds for a single measurement.

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.

Zur Auswirkung digitaler Angebote auf Teilhabechancen von Wohnungslosen JF - Soziale Passagen N2 - Das an der Technischen Hochschule Nürnberg Georg Simon Ohm angesiedelte Forschungsprojekt „SIWo – Smart Inklusion für Wohnungslose“ widmet sich der Fragestellung, welche Informations‑, Unterstützungs- und Beratungsbedarfe bei wohnungslosen Menschen vorliegen und in welcher Form sich die Teilhabechancen für die heterogene Zielgruppe wohnungsloser oder von Wohnungsnot betroffener Menschen mittels digitaler Hilfe und Beratungsangebote verbessern lassen. Hierfür werden zum einen mit Gruppendiskussionen und qualitativen Interviews Bedarfe identifiziert. Zum anderen sollen im Rahmen des Projekts prototypische Lösungsansätze in Form einer plattformübergreifenden Hilfe-App entwickelt, getestet und mit Evaluationsverfahren begleitet werden. Charakteristisch ist dabei die enge interdisziplinäre Zusammenarbeit zwischen Sozialwissenschaft, Informatik und Energietechnik, die partizipative Begleitung des Projekts durch Wohnungslose und andere Stadtakteur*innen, sowie der Fokus auf interaktive Funktionen, die digitalisierte Begegnungsräume ermöglichen und Interaktionen auch zwischen Bevölkerungs-gruppen fördern, die i. d. R. eher wenig miteinander zu tun haben. Dieses Vorgehen begreift somit Wohnungslosigkeit nicht ausschließlich als professionelles Arbeitsfeld der Sozialen Arbeit, sondern als gesamtgesellschaftliche Aufgabe.

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. This workshop provides an opportunity for both sides to meet, share requirements and experiences and develop a best practice course according to industry requirements and academic feasibility.

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.

A1 - Reich, M. A1 - Paschereit, C. O. T1 - Multi-Objective Modeling of Leading-Edge Serrations Applied to Low-Pressure Axial Fans JF - Journal of Engineering for Gas Turbines and Power N2 - A novel modeling strategy is proposed which allows high-accuracy predictions of aerodynamic and aeroacoustic target values for a low-pressure axial fan, equipped with serrated leading edges. 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.
