This study addresses the formation of “viscous fingering” instabilities in structural adhesive joints, which are induced by thermally driven relative displacements during the liquid phase of the adhesive. Using a component-like specimen “bridge specimen,” the dependency of this phenomenon on process temperature and structural stiffness (rivet distance) was characterized. Experimental results reveal that while the relative displacement scales cubically with the free buckling length, the resulting adhesive area reduction follows an exponential trend, leading to a loss of effective bond area of up to 79%, which significantly compromises the joint strength in automotive applications. To predict these process-induced defects, a thermo-chemo-viscoelastic-viscoplastic adhesive model implemented in LS-DYNA was applied. The model combines curing kinetics, viscoelastic relaxation, and pressure-dependent plasticity and features a geometric damage parameter (D) that captures the adhesive area reduction caused by viscous fingering as an exponential function of the accumulated normal strain in the liquid phase. This damage parameter, calibrated on base-specimen level, was transferred to the component geometry. The simulation demonstrated high predictive accuracy with a maximum deviation of the adhesive area reduction of 3.1% compared to experimental data. This validates the model’s capability to predict manufacturing-induced damage in complex hybrid structures solely based on thermal boundary conditions. article_type: original author: - first_name: Mohamad full_name: Al Trjman, Mohamad id: '65415' last_name: Al Trjman - first_name: Felix full_name: Beule, Felix id: '66192' last_name: Beule - first_name: Dominik full_name: Teutenberg, Dominik id: '537' last_name: Teutenberg - first_name: Gerson full_name: Meschut, Gerson id: '32056' last_name: Meschut orcid: 0000-0002-2763-1246 - first_name: Julia full_name: Riese, Julia id: '101499' last_name: Riese orcid: 0000-0002-3053-0534 citation: ama: Al Trjman M, Beule F, Teutenberg D, Meschut G, Riese J.

Systems theory offers powerful concepts to address challenges of growing system complexity and non-systemic design approaches in information systems. Despite its systemic origins, systems theory remains a peripheral topic in IS. The study addresses this gap by introducing a comprehensive framework of 52 systems-theoretical concepts to guide the design of complex IS artifacts. We synthesize scattered systems knowledge from diverse disciplines to provide a unified level of abstraction for complex information system design. We apply the framework to a use case of business reputation systems to show how the systems lens informs the design of a novel, complex information system. We make three key contributions to the literature. First, the framework provides a common ground for interdisciplinary research in information system design. Second, it offers a unified level of abstraction grounded in systems theory that serves as a coherent basis for artifact design. Third, it demonstrates the potential of systems theory as a foundational justificatory knowledge base. Furthermore, we provide guidance on applying the framework across multiple modes of reasoning, alongside further application guidelines. The study thus serves as a bridge between the body of systems knowledge and contextual design in IS. alternative_title: - Design Your System article_type: review author: - first_name: Ulvi full_name: Ibrahimli, Ulvi last_name: Ibrahimli - first_name: Simon full_name: Hemmrich, Simon last_name: Hemmrich - first_name: Axel full_name: Winkelmann, Axel last_name: Winkelmann citation: ama: 'Ibrahimli U, Hemmrich S, Winkelmann A.

Cli-ents who have not worked with a particular consultancy face considerable risk when they place an order while lacking reliable information about the service quality they can expect. There is a strong link between trust and reputation, as the positive reputation of a consultancy can act as a substitute for a new client’s missing individual experience with the provider, fostering trust in the service quali-ty. Thus, creating, maintaining, and demonstrating a good reputation is of signifi-cant importance for consultancies in a very competitive industry.\r\nTo facilitate trustworthy signals, we design and implement a novel reputation mechanism that carries a monetary weight stored on a blockchain network as an immutable, decentralized, and transparent ledger. Based on an implementation in the Ethereum network and subsequent evaluation, we conclude that the reputation mechanism can contribute to leveling information asymmetry and reducing risk while increasing reputation and trust. The mechanism lends itself to being used in other business-to-business scenarios that suffer from similar information asymmetries." author: - first_name: Simon full_name: Hemmrich, Simon id: '83557' last_name: Hemmrich - first_name: Volker full_name: Nissen, Volker last_name: Nissen citation: ama: 'Hemmrich S, Nissen V.

Nearly two decades ago, the service system concept was introduced as a foundational abstraction in service research, drawing on ideas from the service-dominant logic (S-D logic) of marketing. Despite its widespread adoption in service research, particularly in the IS discipline, the service system concept lacks a solid theoretical foundation. This has resulted in conceptual ambiguity and overlap with related constructs, such as service ecosystems. Moreover, it has largely remained a static analytical lens, insufficiently capturing dynamic service phenomena, including value co-creation and co-destruction, as well as the emergence of institutional arrangements. To address these limitations, we propose Luhmann’s systems theory (LST) as a robust framework for conceptualizing service systems as autopoietic (self-creating) systems, in which communication serves as the fundamental mechanism that drives value co-creation. We derive five theoretical propositions from this re-conceptualization that clarify conceptual ambiguity and allow researchers to explore dynamic service phenomena in greater depth. Given LST’s general approach, our conceptualization provides a theoretically grounded, interdisciplinary foundation for advancing service research. article_number: '37' article_type: original author: - first_name: Daniel full_name: Beverungen, Daniel last_name: Beverungen - first_name: Jens full_name: Poeppelbuss, Jens last_name: Poeppelbuss - first_name: Simon full_name: Hemmrich, Simon last_name: Hemmrich - first_name: Taskeen full_name: Iqbal, Taskeen last_name: Iqbal citation: ama: Beverungen D, Poeppelbuss J, Hemmrich S, Iqbal T.

How-ever, the reliable and cost-efficient joining of aluminium components remains a challenge. Mechanical joining methods, such as riveting, are frequently used in the automotive and aerospace construction industries. Rivets are made from heat-treated steels. Compared to steel, the use of aluminium materials for fasten-ers offers several advantages in terms of joining properties, particularly in terms of recyclability, corrosion resistance and reduced weight of the joined structure. Additionally, the manufacturing process is shorter since aluminium fasteners do not require coating. However, aluminium rivets can often not be used due to the insufficient mechanical strength of the fastener material in relation to the joining component materials.\r\nThis study systematically investigates the requirements for using solid alu-minium self-piercing rivets. The influence of rivet geometry adjustments on the joint quality is analysed using numerical simulation. The results are used to derive and evaluate an optimised rivet geometry for joining pure aluminium sheets. On this basis, solid self-drilling rivets with optimised geometry are manufactured from particle-reinforced aluminium produced in a continuous extrusion process by machining. The integration of particles increases the material’s strength. Exper-imental tests are conducted to evaluate the use of optimised solid self-piercing rivets. The quality-relevant parameters are determined and evaluated based on macrographs of the joints." author: - first_name: Steffen full_name: Koch, Steffen last_name: Koch - first_name: Joshua full_name: Weber, Joshua last_name: Weber - first_name: Gerson full_name: Meschut, Gerson last_name: Meschut - first_name: Claudia full_name: Stadelmann, Claudia last_name: Stadelmann - first_name: Wolfgang full_name: Böhm, Wolfgang last_name: Böhm - first_name: Marion full_name: Merklein, Marion last_name: Merklein citation: ama: 'Koch S, Weber J, Meschut G, Stadelmann C, Böhm W, Merklein M.

As programmable digital architectures, they both shape and are shaped by teachers’ and students’ practices. Building on two Action Research projects in German schools, the article concentrates on the reproduction of inequality within platformized classrooms. It uses the focus point of translation software usage to explore inscriptions into digital architectures. Analysing breakdowns of translation software usage among students who speak German as a second/foreign language, the article focuses on inscribed power dynamics within translation software, the mismatch between students’ practices and the imagined user, and the discrepancy between software logics and the educational setting. Discussing teachers’ invisible work, care and belonging in platformized education settings, the article highlights the epistemic inscriptions within technology. It describes how dataveillance and testing break down when students use translation software, thereby highlighting teachers’ shift towards creating a collective understanding. Lastly, the article discusses teachers’ autonomy within post-platform education by highlighting the limitations of currently available software products and software production. author: - first_name: Rebecca full_name: Schmidt, Rebecca id: '94416' last_name: Schmidt orcid: https://orcid.org/0000-0002-2516-359X citation: ama: Schmidt R.

Companies must comply with numerous regulations for such product approvals. This results in requirements for processes, methods, tools and organizations throughout the product life cycle. A proven approach to handling regulatory requirements is the application of product lifecycle management (PLM) platforms. Applying PLM platforms (e.g. Teamcenter, 3DExperience) poses challenges in designing compliant processes as well as adapting methods and tools. For example, in medical technology, ISO 13485 specifies an industry-specific product engineering process. The exemplary adaptations of requirements engineering methods and related support – e.g. MBSE including Requirements Diagrams – are not intuitively apparent. Existing literature primarily regards these regulation-related challenges as boundary conditions, offering only vague operational solutions. Companies struggle to align PLM processes with regulatory requirements, yet few methods exist to support this integration. In this paper, a method is proposed that supports the application of regulation-centered PLM platforms and reduces effort in product approvals. The method is developed by applying a five-step approach. Existing literature on process models for applying PLM platforms is identified (1). The identified approaches are then analyzed to determine whether and to what extent they consider regulations in applying PLM platforms (2). Based on identified partial solutions from literature and findings from industry workshops, a new method is developed (3). The method comprises strategic level, process level, data level, pilot level, and operation level. Validation is conducted within a German medical technology company, containing proof of applicability determined through a pilot project (4) and proof of concept achieved through interviews (5). The method is applied to regulation-centered PLM for the use case ‘requirements engineering’. The concept is confirmed by experts in terms of applicability and transferability. The method supports engineers in applying regulation-centered PLM platforms, leading to reduced effort. author: - first_name: Iris full_name: Gräßler, Iris id: '47565' last_name: Gräßler orcid: 0000-0001-5765-971X - first_name: Jan Niklas full_name: Pfeifer, Jan Niklas id: '62841' last_name: Pfeifer - first_name: Denis full_name: Trost, Denis last_name: Trost citation: ama: 'Gräßler I, Pfeifer JN, Trost D.

Rather, what is crucial is how technical, organizational, and communicative dimensions are interconnected and whether this results in recognizable added value for researchers in their day-to-day work. In this context, both intrinsic and extrinsic motivational factors influence the willingness to actively and continuously use research data management (RDM) systems.This article synthesizes experiences from two collaborating subprojects on information infrastructure (INF) within two Collaborative Research Centers. Both develop and operate RDM structures for interdisciplinary research consortia in the field of engineering and face comparable challenges: Adhering to the rules of good scientific practice when handling data is under pressure in today’s world; the benefits of individual data entries sometimes remain abstract, and additional process steps can reduce acceptance of technical solutions. The effort involved is primarily evaluated based on whether, from the researchers’ perspective, it yields a recognizable benefit. Based on this, specific approaches for user-oriented integration of different RDM levels are presented. These include the integration of RDM tools into existing research tools and workflows, cross-subproject access to information, as well as SPARQL-based search capabilities and future approaches to knowledge exploration. One concrete example is an implemented adapter that automatically transfers data sets from existing Excel files and electronic lab notebook entries from eLabFTW into the RDM system, thereby reducing the number of required process steps. Since the adapter was deployed, a measurable increase in the number of datasets imported into the RDM system has been observed. Such technical and procedural measures are complemented by workshops, personalized support, systematic feedback, and the continuous adaptation of the systems to the needs of researchers.This poster illustrates that RDM systems must be understood as sociotechnical systems. It is only through the interplay of infrastructure, process integration, communication, and perceived benefits that individual RDM developments can be transformed into a practical service. The collaboration between the two INF subprojects makes it possible to pool experiences, solution approaches, and transferable design principles across institutions and research consortia.' - lang: ger text: 'Die erfolgreiche Bereitstellung von Forschungsdaten hängt nicht allein von der technischen Qualität einzelner Systeme ab.

Beide entwickeln und betreiben FDM-Strukturen für interdisziplinäre Forschungsverbünde im ingenieurwissenschaftlichen Kontext und stehen vor vergleichbaren Herausforderungen: Der Umgang mit Daten nach den Regeln der guten wissenschaftlichen Praxis steht in der heutigen Zeit unter Druck, der Nutzen einzelner Eingaben bleibt mitunter abstrakt und zusätzliche Prozessschritte können die Akzeptanz technischer Lösungen verringern. Aufwand wird dabei wesentlich danach bewertet, ob ihm aus Sicht der Forschenden ein erkennbarer Nutzen gegenübersteht.Ausgehend davon werden konkrete Ansätze zur nutzerorientierten Verbindung unterschiedlicher FDM-Ebenen vorgestellt. Dazu zählen die Integration von FDM-Tools in bestehende Forschungswerkzeuge und Arbeitsabläufe, der teilprojektübergreifende Zugang zu Informationen sowie SPARQL-basierte Recherchemöglichkeiten und perspektivische Wissensexploration. Ein konkretes Beispiel ist ein implementierter Adapter, der Datensätze automatisiert aus bestehenden Excel-Dateien und aus elektronischen Laborbüchereinträgen von eLabFTW in das FDM-System überträgt und damit zusätzliche Prozessschritte reduziert. Nach Bereitstellung des Adapters lässt sich ein messbarer Anstieg der in das FDM-System eingespielten Datensätze beobachten. Ergänzt werden solche technischen und prozessualen Maßnahmen durch Workshops, persönliche Unterstützung, systematisches Feedback und die kontinuierliche Anpassung der Systeme an die Bedarfe der Forschenden.Der Beitrag verdeutlicht, dass FDM-Systeme als soziotechnische Systeme verstanden werden müssen. Erst das Zusammenspiel von Infrastruktur, Prozessintegration, Kommunikation und wahrgenommenem Nutzen macht aus einzelnen FDM-Entwicklungen einen praxistauglichen Dienst.

Funding organizations have started to require that research applicants pay attention to inclusion and diversity by considering gender dimensions and other diversity factors in their project plans and ensuring gender equality during execution. Based on an extensive literature research and expert discussions on how to develop and implement diversity strategies in large collaborative research projects, we argue that there is a lack of practical advice in existing literature. Drawing from our own experiences in conceptualizing and implementing a Diversity Program across four universities in Germany, we propose a framework for effectively integrating diversity into collaborative research initiatives across various academic fields. author: - first_name: Mariya full_name: Lorke, Mariya last_name: Lorke - first_name: Rena full_name: Amelung, Rena last_name: Amelung - first_name: Peter full_name: Kuchling, Peter last_name: Kuchling - first_name: Benjamin full_name: Paaßen, Benjamin last_name: Paaßen - first_name: Miriam full_name: Pein-Hackelbusch, Miriam last_name: Pein-Hackelbusch - first_name: Franziska Margarete full_name: Schloots, Franziska Margarete id: '33185' last_name: Schloots orcid: 0009-0008-9673-2615 - first_name: Klara full_name: Schulz, Klara last_name: Schulz - first_name: Annette full_name: Nauerth, Annette last_name: Nauerth citation: ama: 'Lorke M, Amelung R, Kuchling P, et al.

When operated under partially flooded conditions, they provide significant mass transfer improvement compared to common structured packings. In this work, a rate-based model including novel mass transfer correlations is presented and validated using a comprehensive experimental database for the reactive absorption of CO2 into aqueous monoethanolamine. The proposed rate-based approach is capable of accounting for axial dispersion, thereby enabling the evaluation of the effect of liquid-phase backmixing on the mass transfer performance. The validated rate-based model is used to evaluate the separation performance of sandwich packings. Compared with structured packings, up to 10 % higher mass transfer rates are obtained. article_number: '122681' article_type: original author: - first_name: Patrick full_name: Franke, Patrick id: '93922' last_name: Franke - first_name: Markus full_name: Schubert, Markus last_name: Schubert - first_name: Uwe full_name: Hampel, Uwe last_name: Hampel - first_name: Eugeny Y. full_name: Kenig, Eugeny Y. id: '665' last_name: Kenig citation: ama: Franke P, Schubert M, Hampel U, Kenig EY.

They are recommended for long-term use cases like e.g. firmware signing. However, stateful signature schemes require to properly manage a so-called state. In stateful signature schemes like LMS and XMSS, signing keys consist of a set of keys of a one-time signature scheme and it has to be guaranteed that each one-time key is used only once. This is done by updating a state in each signature computation, basically recording which one-time keys have already been used. While this is straightforward in centralized systems, in distributed systems like secure enclaves consisting of e.g. multiple hardware security modules (HSMs) with limited communication keeping a distributed state that at any point in time is consistent among all parties involved presents a challenge. This challenge is not addressed by the current standardization processes. \r\nIn this paper we present a security model for the distributed key management of post-quantum secure stateful signatures like XMSS and LMS. We also present a simple, efficient, and easy to implement protocol proven secure in this security model, i.e. the protocol guarantees at any point in time a consistent state among the parties in a distributed system, like a distributed security enclave. The security model is defined in the universal composabilty (UC) framework by Ran Canetti by providing an ideal functionality for the distributed key management for stateful signatures. Hence our protocol remains secure even if arbitrarily composed with other instances of the same or other protocols, a necessity for the security of distributed key management protocols. Our main application are security enclaves consisting of HSMs, but the model and the protocol can easily be adapted to other scenarios of distributed key management of stateful signature schemes." author: - first_name: Johannes full_name: Blömer, Johannes id: '23' last_name: Blömer - first_name: Henrik full_name: Bröcher, Henrik id: '41047' last_name: Bröcher orcid: 0009-0008-3938-5485 - first_name: Volker full_name: Krummel, Volker last_name: Krummel - first_name: Laurens Alexander full_name: Porzenheim, Laurens Alexander id: '47434' last_name: Porzenheim citation: ama: Blömer J, Bröcher H, Krummel V, Porzenheim LA.

Their query rewriting algorithms focus on languages like conjunctive queries and their unions, which were developed for relational data and are poorly suited for graph data. Moreover, they also limit the expressiveness of the ontology languages that admit rewritings, restricting them to those that enjoy the so-called FO-rewritability property. Rewritings have thus focused on the DL-Lite family of Description Logics. In this paper, we propose a technique for rewriting a family of navigational queries for a suitably tailored fragment of ELHI. Leveraging navigational features in the target query language, we can include some widely-used axiom shapes not supported by DL-Lite. We implemented a proof-of-concept prototype that rewrites into Cypher queries, and tested it on a real-world cognitive neuroscience use case with promising results. author: - first_name: Bianca full_name: Löhnert, Bianca last_name: Löhnert - first_name: Nikolaus full_name: Augsten, Nikolaus last_name: Augsten - first_name: Cem full_name: Okulmus, Cem id: '114410' last_name: Okulmus orcid: 0000-0002-7742-0439 - first_name: Magdalena full_name: Ortiz, Magdalena last_name: Ortiz citation: ama: 'Löhnert B, Augsten N, Okulmus C, Ortiz M.

Studies on life cycle assessment and life cycle engineering of vehicle lightweight structures are mainly limited to these privately owned cars and the impact category of climate change. In this paper, a method for life cycle assessment-based engineering of lightweight structures in vehicles for various mobility system applications, including on-demand mobility services, is developed. The method enables the holistic life cycle assessment of lightweight structures in different mobility system applications considering parameter changes at the upstream products, component, subsystem, vehicle and mobility system levels, as well as the integration of results into engineering activities. A case study is used to show that the vehicle and mobility system application of lightweight structures can significantly influence their environmental impacts and the selection of ecologically preferable product designs. The application in vehicles for on-demand mobility services can lead to an increase in absolute use stage energy demand and environmental impacts compared to applications in privately owned vehicles for motorized individual transport. However, normalized to the transport performance provided, the lifecycle environmental impacts of structural components in vehicles for on-demand mobility services can be lower than in vehicles for motorized individual transport. The paper contributes methodically and with quantitative results to improved decision making in life cycle engineering activities for lightweight structures in mobility system applications. article_number: '101058' article_type: original author: - first_name: Moritz full_name: Ostermann, Moritz id: '44763' last_name: Ostermann orcid: https://orcid.org/0000-0003-1146-0443 - first_name: Eric full_name: Dierkes, Eric last_name: Dierkes - first_name: Thorsten full_name: Marten, Thorsten id: '338' last_name: Marten orcid: 0009-0001-6433-7839 - first_name: Thomas full_name: Tröster, Thomas id: '553' last_name: Tröster citation: ama: Ostermann M, Dierkes E, Marten T, Tröster T.

However, the role of V&V engineers is often not given sufficient attention. Based on a systematic literature analysis and practical observations, a four-step method for Test-oriented Resilient Requirements Engineering (ToRRE) is developed. The steps are planning V&V, executing V&V activities, documenting V&V activities and analyzing results of V&V activities. Applying ToRRE ensures continuous information flow and traceability. Engineers are enabled to analyze requirements using engineering artifacts connected through Model-Based Systems Engineering. Adopting methods for Model-Based Effect Chain analysis to evaluated test cases and test scenarios, conclusions on requirements engineering and change management are enabled. The method is evaluated in an EU research project. author: - first_name: Iris full_name: Gräßler, Iris id: '47565' last_name: Gräßler orcid: 0000-0001-5765-971X - first_name: Marcel full_name: Ebel, Marcel id: '81788' last_name: Ebel orcid: https://orcid.org/0009-0007-5400-4436 citation: ama: 'Gräßler I, Ebel M.
