Item type:Publication, Access status: with files , Stop saying "AI"(Springer, 2026-05-27); ; ; Across academia, industry, and government, “AI” has become central in research and development, regulatory debates, and promises of ever faster and more capable decision-making and action. In numerous domains, especially safety-critical ones, there are significant concerns over how “AI” may affect decision-making, responsibility, or the likelihood of mistakes (to name only a few categories of critique). However, for most critiques, the target is generally “AI”, a broad term admitting many (types of) systems used for a variety of tasks and each coming with its own set of limitations, challenges, and potential use cases. In this article, we focus on the military domain as a case study and present both a loose enumerative taxonomy of systems captured under the umbrella term “military AI”, as well as discussion of the challenges of each. In doing so, we highlight that critiques of one (type of) system will not always transfer to other (types of) systems. Building on this, we argue that in order for debates to move forward fruitfully, it is imperative that the discussions be made more precise and that “AI” be excised from debates to the extent possible, especially as discussions move more toward discrete systems and use cases. Researchers, developers, and policy-makers should make clear exactly what systems they have in mind and what possible benefits and risks attend the deployment of those particular systems. While we focus on AI in the military as an exemplar for the overall trends in discussions of “AI”, the argument’s conclusions are broad and have import for discussions of AI across a host of domains.Publicationtype: Journal Article62 11 - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Access status: without files , Design of a UAM ground infrastructure network with respect to maintenance capacity requirements(International Council of the Aeronautical Sciences, 2024); ; ; Before a successful introduction of Urban Air Mobility can be achieved, numerous challenges must be ad-dressed, one of which is the development of efficient traffic networks with all associated components. Previous studies have already examined UAM networks in terms of fleet capacity requirements, energy supply, and parking positions. The aim of this study is the further development of these methods to analyze the necessary capacity of maintenance infrastructure for an eVTOL fleet. Another aspect of this work is to investigate the im-pact of the centralization degree of a maintenance facility network. While centralized networks have potential to reduce redundancies, decentralized networks may help to reduce detours caused by empty relocation flights to maintenance facilities. Therefore, necessary maintenance intervals are first investigated. Based on these insights, maintenance processes are then planned for an exemplary fleet operating in the City of Hamburg (Germany). Finally, the overall demand for maintenance services is quantified at the network level and the potential benefits of a decentralized maintenance facility network are evaluated with regard to the reduction of empty flights.Publicationtype: Conference Paper24 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: with files , Methodik zur ganzheitlichen Analyse bodengebundener Infrastruktur für die Urban Air Mobility(Deutsche Gesellschaft für Luft- und Raumfahrt - Lilienthal-Oberth e.V. (DGLR), 2023-11-10); ; ; ; Dieser Artikel stellt den methodischen Prozess einer Szenarienentwicklung sowie einer simulationsgestützten Analyse für die bodengebundene Infrastruktur von UAM dar. Als innovative Lösung verspricht UAM im Personentransport Angebote im Gesamtverkehr zu schaffen, um das zukünftige Mobilitätsangebot in Metropolregionen zu verbessern. Die Gestaltung der Nachfrageszenarien befindet sich in einer stetigen Aushandlung zwischen den Akteuren und wird beeinflusst von der technischen Entwicklung, der sozioökonomischen Realisierbarkeit und den zugrunde liegenden Diskursen, die diese Form der Mobilität umgeben. Die Anforderungen an die bodengebundene Infrastruktur sind essentiell für eine realistische Beurteilung der Kapazitäten und Flugmissionen, der städteplanerischen und architektonischen Umsetzung, den Synergien zu anderen Verkehrssystemen sowie einer Berücksichtigung sozialer Aspekte in der Stadt. Der erste methodische Baustein beleuchtet den kreativen Prozess dieser Szenarienentwicklung, einschließlich einer Faktorenanalyse, der Ableitung schlüssiger Nachfrageszenarien sowie der Identifizierung konkreter Standorte für Vertiports am Beispiel der Metropolregion Hamburg. Vier thematische Szenarien werden in diesem Kontext tiefergehend diskutiert: die Anbindung peripherer Räume, Pendlerbewegungen, touristische Nutzung sowie die Überwindung von Mobilitätsengpässen. Im zweiten Abschnitt liegt der Fokus auf der technischen Umsetzung und Analyse der Topologien, Wartungs- und Reparatursystemen, dem Energiemanagement sowie der Wechselwirkung zwischen diesen Subsystemen.Publicationtype: Conference Paper122 142 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: without files , Vertiports task areas and functional sequences for basic operations in urban spaceTechnological progress in Advanced Air Mobility (AAM) enables development of Urban Air Mobility (UAM) concepts and networks. These concepts rely on ground-based infrastructure that requires different vertiports with different characteristics depending on the location, tasks (from vertistops, traffic hubs to maintenance hubs) and their responsibilities. For the planning and design, task-related functional processes, their variants, the respective functions and their parameters are important key factors. The elaboration of processes and functional flows for the different task areas of vertiports has so far only been considered in a rudimentary way or at a very high level of abstraction and is not well documented in the scientific literature. This paper focuses on a solution space oriented view of functions and processes and their adaptation to individual requirements for single vertiport configurations and provides an approach to represent these functions as BPMN Swimmlane diagrams. In the scope of this paper the main contribution lies in the representation of the safety analysis and MRO (Maintenance, Repair and Overhaul) functions on vertiports.Publicationtype: Conference Paper23 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: without files , Innovative urban air mobility from the perspective of the Hamburg metropolitan regionFor the future of urban mobility, further developments in the fields of automation, communication and energy storage technologies will enable the expansion of traffic space into the air. Various concepts and scenarios of urban air mobility (UAM) are already part of current research. In addition to the investigation of relevant physical effects and system-internal constraints, a view including the external relationships and general conditions is essential for the design, acceptance and success of the UAM systems. Several projects (i-LUM, ULTRAS, UDVeo, LUV, Vertiport) with the participation of various Hamburg research institutions bundle a multitude of competences to develop UAM scenarios for the Hamburg metropolitan region and other regions. UAM scenarios are evaluated i.a. in terms of time, cost, noise, energy consumption, acceptance and the ease of integration. The evaluation considers societal interactions, legal frameworks, demand modeling, concept development, ground-based infrastructure, airspace organization and operation, as well as overall system modeling. This paper gives an overview about the disciplinary and methodical approach and setup of these UAM projects.Publicationtype: Conference Paper197 - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Access status: without files , Sensor concept for solving the direct kinematics problem of the Stewart-Gough platformOne of the main tasks in robotics is to precisely connect the robot's coordinate system with the world's coordinate system. For parallel mechanisms, this is a challenging task due to the direct kinematics problem, which is usually solved by using iterative algorithms to search for the mobile platform's position and orientation or by adding auxiliary sensors. In this paper, a sensor concept for solving the direct kinematics problem of the Stewart-Gough platform is presented where only three inertial measurement units are used with the aim to renounce length sensors as well as initial and, in some cases, external pose measurements.Publicationtype: Conference Paper124
