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."}],"file":[{"content_type":"application/pdf","relation":"main_file","success":1,"creator":"mohamada","date_created":"2026-03-14T18:50:31Z","date_updated":"2026-03-14T18:50:31Z","file_name":"Experimental characterization and numerical analysis of the influence of the CED coating process on viscous fingering formation in hybrid-jointed mixe.pdf","access_level":"closed","file_id":"64917","file_size":14668789}],"publisher":"Informa UK Limited","date_created":"2026-03-14T18:43:41Z","title":"Experimental characterization and numerical analysis of the influence of the CED coating process on viscous fingering formation in hybrid-jointed mixed structures","year":"2026"},{"type":"journal_article","status":"public","_id":"65311","user_id":"83557","department":[{"_id":"195"}],"article_type":"review","alternative_title":["Design Your System"],"extern":"1","publication_status":"published","publication_identifier":{"unknown":["1529-3181"]},"jel":["D83","L14","D83","O33","C63","P"],"citation":{"ama":"Ibrahimli U, Hemmrich S, Winkelmann A.

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."}],"external_id":{"unknown":["https://aisel.aisnet.org/cais/vol58/iss1/37/"]},"keyword":["Information Systems Research","Systems Theory","System Complexity","System Design","Design Science"],"language":[{"iso":"eng"}],"quality_controlled":"1","year":"2026","publisher":"AIS","date_created":"2026-04-02T04:19:09Z","title":"Bridging Systems Theory and Information Systems: A Framework for Designing Complex Information Systems"},{"title":"A blockchain-based reputation system for consulting","date_created":"2026-04-02T04:06:47Z","author":[{"first_name":"Simon","last_name":"Hemmrich","full_name":"Hemmrich, Simon","id":"83557"},{"last_name":"Nissen","full_name":"Nissen, Volker","first_name":"Volker"}],"date_updated":"2026-04-02T04:32:01Z","citation":{"bibtex":"@inbook{Hemmrich_Nissen_2026, title={A blockchain-based reputation system for consulting}, booktitle={ Advanced Studies in Consulting Research and Digitalization – A Scientific Update on the Digital Transformation of the Consulting Industry.

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.","lang":"eng"}],"publication":" Advanced Studies in Consulting Research and Digitalization – A Scientific Update on the Digital Transformation of the Consulting Industry.

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."}],"publication":"Electronic Markets","language":[{"iso":"eng"}],"keyword":["Service system","Service ecosystem","Systems theory","Service research"],"ddc":["380"]},{"citation":{"ama":"Löhnert B, Augsten N, Okulmus C, Ortiz M.

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.","lang":"eng"}],"publication":"The Semantic Web - 22nd European Semantic Web Conference, {ESWC} 2025, Portoroz, Slovenia, June 1-5, 2025, Proceedings, Part {I}","keyword":["Ontology-based Data Access","Property Graphs","Navigational Queries"],"language":[{"iso":"eng"}]},{"abstract":[{"text":"To reduce transport-related environmental impacts, innovative mobility system approaches such as on-demand services are being developed. These can include operating vehicles that differ regarding their characteristics and application profile from privately owned cars in motorized individual transport. 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.","lang":"eng"}],"publication":"Cleaner Engineering and Technology","keyword":["Life cycle assessment","Life cycle engineering","Lightweight design","On-demand mobility","Shared mobility","Mobility services"],"language":[{"iso":"eng"}],"year":"2025","quality_controlled":"1","title":"Life cycle engineering of lightweight structures in vehicles for on-demand mobility services","publisher":"Elsevier BV","date_created":"2025-08-06T06:53:27Z","status":"public","type":"journal_article","article_number":"101058","article_type":"original","_id":"60885","project":[{"grant_number":"19S23003Q","name":"NeMobil: NeMo.bil – System kooperierender Fahrzeuge für einen individualisierten Öffentlichen Verkehr","_id":"780"},{"grant_number":"005-2111-0020 ","_id":"405","name":"Climate bOWL: Climate bOWL: Climate neutral Business in Ostwestfalen-Lippe"}],"department":[{"_id":"9"},{"_id":"321"},{"_id":"149"}],"user_id":"44763","intvolume":"        28","citation":{"bibtex":"@article{Ostermann_Dierkes_Marten_Tröster_2025, title={Life cycle engineering of lightweight structures in vehicles for on-demand mobility services}, volume={28}, DOI={<a href=\"https://doi.org/10.1016/j.clet.2025.101058\">10.1016/j.clet.2025.101058</a>}, number={101058}, journal={Cleaner Engineering and Technology}, publisher={Elsevier BV}, author={Ostermann, Moritz and Dierkes, Eric and Marten, Thorsten and Tröster, Thomas}, year={2025} }","mla":"Ostermann, Moritz, et al. “Life Cycle Engineering of Lightweight Structures in Vehicles for On-Demand Mobility Services.” <i>Cleaner Engineering and Technology</i>, vol. 28, 101058, Elsevier BV, 2025, doi:<a href=\"https://doi.org/10.1016/j.clet.2025.101058\">10.1016/j.clet.2025.101058</a>.","short":"M.

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.","lang":"eng"}],"publication":"Diversity & Inclusion Research","type":"journal_article","language":[{"iso":"eng"}],"keyword":["collaborative research projects","diversity strategy","gender equality"],"department":[{"_id":"574"}],"user_id":"33185","_id":"61445"},{"status":"public","type":"journal_article","article_number":"27","article_type":"original","file_date_updated":"2025-04-04T06:19:38Z","_id":"59335","project":[{"_id":"1250","name":"SHAPE : Gestaltung von Dienstleistungsentwicklungsprozessen und lnnovationspartnerschaften mit Unternehmen"}],"department":[{"_id":"195"}],"user_id":"59677","intvolume":"        35","jel":["M10"],"citation":{"bibtex":"@article{Böhmann_Roth_Satzger_Benz_Beverungen_Boes_Breidbach_Gersch_Gudergan_Hogreve_et al._2025, title={Continuous value shaping: A boundary concept for innovating service innovation approaches}, volume={35}, DOI={<a href=\"https://doi.org/10.1007/s12525-025-00771-1\">10.1007/s12525-025-00771-1</a>}, number={127}, journal={Electronic Markets}, publisher={Springer Science and Business Media LLC}, author={Böhmann, Tilo and Roth, Angela and Satzger, Gerhard and Benz, Carina and Beverungen, Daniel and Boes, Andreas and Breidbach, Christoph and Gersch, Martin and Gudergan, Gerhard and Hogreve, Jens and et al.}, year={2025} }","short":"T.

While a variety of disciplines are developing new approaches to drive service innovation, this is primarily done in isolation and generates only fragmented solutions. Sociological theory has proposed “boundary objects” as an effective umbrella for communication and cooperation among communities. Therefore, we introduce continuous value shaping (CVS) as a boundary object describing service innovation approaches along five principles. We reflect on this concept through the different disciplinary lenses of researchers in service marketing, information systems, service engineering, sociology of work, and innovation management. These perspectives highlight how the CVS principles already connect to discourses within the individual disciplines. However, the CVS concept will not only provide an umbrella to embrace existing activities in different academic disciplines. It also assists to identify research themes that will benefit from uniting the power of these disciplines, and it can serve as an integrating framework to conceptualize complex service innovation approaches. Thus, the CVS concept should guide both researchers and practitioners to develop and implement novel innovation and transformation efforts—in and across organizations.","lang":"eng"}],"file":[{"file_size":920032,"file_name":"Continuous Value Shaping - EM.pdf","file_id":"59336","access_level":"closed","date_updated":"2025-04-04T06:19:38Z","date_created":"2025-04-04T06:19:38Z","creator":"dabe","success":1,"relation":"main_file","content_type":"application/pdf"}],"publication":"Electronic Markets","keyword":["Continuous value shaping (CVS)","Service research","Service innovation","Digitalization","Sustainability","Interdisciplinary research"],"ddc":["380"],"language":[{"iso":"eng"}],"external_id":{"unknown":["https://link.springer.com/article/10.1007/s12525-025-00771-1"]},"year":"2025","quality_controlled":"1","issue":"1","title":"Continuous value shaping: A boundary concept for innovating service innovation approaches","publisher":"Springer Science and Business Media LLC","date_created":"2025-04-04T06:10:26Z"},{"publication_status":"published","citation":{"apa":"Sri Ramulu, H., Rotthaler, A.

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.","lang":"eng"}]},{"status":"public","publication":"Journal of Manufacturing Processes","type":"journal_article","language":[{"iso":"eng"}],"keyword":["Industrial and Manufacturing Engineering","Management Science and Operations Research","Strategy and Management"],"department":[{"_id":"157"}],"user_id":"66459","_id":"52201","page":"92-108","intvolume":"       116","citation":{"ama":"Han D, Kappe F, Vorderbrüggen J, Jendrny J, Gorr E, Meschut G.

For example, property damage to shared accommodations imposes burdens on both sharing platforms and hosts, especially if misbehaving guests purposefully, not coincidentally conceal, or fail to report damages. Such misbehavior might be facilitated by remote listing management and the lack of face-to-face interactions between hosts and guests. Therefore, this study investigated the effects of host–guest interaction modes (face-to-face, online-only) and frequency on guests’ misbehavior concealment intentions. Social identification and irritation emerged as bright- and dark side mediators, respectively. Guests who interacted face-to-face (vs. online-only) with hosts exhibited weaker intentions to conceal their misbehavior due to increased social identification. Platforms can elicit social identification by engaging guests in virtual communities. However, when face-to-face interactions become excessive, guests experience irritation and are more likely to conceal their misbehavior. These insights offer practical implications for both peer-to-peer sharing platforms and hosts."}],"publication":"Journal of Business Research"},{"publication_status":"published","citation":{"ieee":"S.

This paper explores the value of a reputation system for a business-to-business (B2B) context and focuses on three novel solutions for designing reputation systems. These solutions include selling ratings, conducting ratings as payments, and employing a counter-rating mechanism. We interview buyers to fathom the added value of these solutions in different contexts. Our findings suggest that such a system is useful for companies acting in less transparent markets and also helps when companies already have a good market overview.
