Hence, hybrid structures made of aluminum and steel materials are increasingly being used in automotive applications. Due to limitations in the quality of resistance spot welding, self-piercing riveting can be used as an alternative process to join sheets from different material groups. The aim of this project is to develop a computational method to assess the self-piercing riveted components subjected to the cyclic loads. To achieve this goal, two approaches are followed: Evaluation unsing internal forces: A substitute model is developed to describe the stiffness of self-piercing riveted joints subjected to different loading conditions. The parameters of the substitute model are identified and the internal force components acting on the joint are evaluated. The model provides the basis for the subsequent fatigue life estimation of self-piercing riveted components. For joints subjected to low bending moments, the fatigue life of components can be estimated accurately. Due to lack of specimen geometries producing pure bending and the combination of tension-bending forces, it is not possible to estimate the fatigue life of complex components subjected to high bending moments. Based on the results of [Mesc 16], the methodology is further developed to determine the stresses acting on the joint and to characterize the joining point with the use of simulations. The local concept proposed in the FKM guideline nonlinear provides the basis for the analytical assessment of self-piercing riveted components. In this regard, the cyclic behavior of the material and the local stresses are required as input data. The cyclic behavior of the aluminum EN AW-6181A-T6 and steel HX340LAD sheets were already determined in the previous project. Subsequently, in this project the properties of the rivet made of 38B2 steel are identified. The finite element analysis using elastic-plastic material behavior is used to determine the stresses in the joint subjected to the cyclic loads. To verify the model, the results of simulations and experiments are compared concerning the crack initiation zone as well as the determined number of cycles. To determine the stresses that can be used for the analytical assessment, the damage relevant load components need to be identified. In this regard, it is recommended to use the normal stress perpendicular to the crack propagation direction, the stress of crack opening mode I. Using the damage parameter PRAM and considering the support factors according to the FKM guideline nonlinear, a reliable estimation of the crack initiation zone within the joint is possible. Regarding the joint made of aluminum sheet EN AW-6181A, the methodology is able to provide promising results. However, regarding the joints made of aluminum EN AW-6181A and steel HX340LAD sheets, there is still potential to improve the results. The reasons for this are described in chapter 7.2.5 and 7.2.6. An analytical fatigue assessment is relatively easy to achieve with procedure 1. However, contrary to the objective formulated above, expensive fatigue tests are necessary to determine the failure conditions (strength values). This disadvantage can be circumvented by determining the strength information of individual joining points under different load types using procedure 2. The latter, in return, is not suitable for the assessment of complex components with several joining points. Due to the increasing calculation times of the simulation, the application in this case is not economically reasonable. By the described combination of method 1 and 2, the disadvantages of the two individual concepts can be compensated. An analytical fatigue assessment of self-piercing riveted components can be carried out based on the cyclic material behavior. The objective of the project was achieved.' - lang: ger text: 'Hybridstrukturen aus Aluminium- und Stahlblechen, wie sie bei modernen Leichtbaukonstruktionen immer häufiger vorkommen, sind oft ein guter Kompromiss zwischen Festigkeit und Gewicht der Konstruktion. Das in der Blechverarbeitung häufig eingesetzte Widerstandspunktschweißen führt bei der Verbindung von artverschiedenen Werkstoffen häufig nicht zu der gewünschten Verbindungsqualität. In solchen Fällen kann das mechanische Fügen mittels Halbhohlstanzniet eine gute Alternative darstellen. Das Ziel dieses Forschungsprojektes ist die Entwicklung einer Berechnungsmethode zur Auslegung von zyklisch belasteten halbhohlstanzgenieteten Bauteilen. Die zu entwickelnde Berechnungsmethodik soll dem späteren Anwender eine Bauteilauslegung mit möglichst geringem experimentellem Aufwand ermöglichen. Um dieses Ziel zu erreichen, werden zwei Vorgehensweisen verfolgt: Vorgehensweise über örtliche Schnittlasten: Für komplexe Geometrien wird ein Ersatzmodell des Fügepunktes entwickelt, welches dieselben Steifigkeiten wie der reale Fügepunkt aufweist. Mit den Kraftkomponenten, die auf den Ersatzfügepunkt wirken und dessen simulativer oder experimenteller Charakterisierung, kann die Lebensdauer für komplexe Bauteile abgeschätzt werden. Für Fügeverbindungen, bei denen am Fügepunkt nur eine geringe Biegebeanspruchung auftritt, kann mit Hilfe des experimentell charakterisierten Fügepunktes eine treffsichere Lebensdauerabschätzung durchgeführt werden. Aufgrund des Fehlens einer geeigneten Probenform zur Charakterisierung des Fügepunktes unter Biegebelastung zeigt die Treffsicherheit bei hohen Biegebeanspruchungen am Fügepunkt Verbesserungspotenzial. Auf Basis der Ergebnisse aus [Mesc 16] wird die Methodik zur Ermittlung der Beanspruchungen in der Fügeverbindung weiterentwickelt und Erkenntnisse über Einflüsse auf die örtlichen Beanspruchungen gewonnen, um den Fügepunkt simulativ charakterisieren zu können. Eine solche Möglichkeit bietet die Anwendung des Örtlichen Konzeptes, das in der FKM-Richtlinie nichtlinear für homogene Werkstoffe standardisiert ist. Der dort beschriebene Algorithmus wird als Ausgangspunkt für die rechnerische Auslegung von Stanznietverbindungen genommen und an deren Bedürfnisse angepasst. Als Eingangsdaten zur Auslegung werden das zyklische Werkstoffverhalten und die Beanspruchungen in der Fügeverbindung benötigt. Das zyklische Werkstoffverhalten der Bleche aus Aluminium EN AW-6181A-T6 und Stahl HX340LAD wurde im Vorgängerprojekt bereits bestimmt. In diesem Projekt folgt die noch fehlende Charakterisierung des Nietwerkstoffs, des Stahls 38B2 H4. Die Bestimmung der Beanspruchungen in der Fügeverbindung unter zyklischer Belastung erfolgt mit Hilfe einer Finite-Elemente-Analyse mit elastisch-plastischem Verformungsverhalten. Verifiziert werden die Simulationsergebnisse, indem die Versagensorte aus Simulation und Versuch sowie die berechneten und experimentellen Lebensdauern miteinander verglichen werden. Zur Berechnung der Beanspruchungen muss die schädigungsrelevante Beanspruchungsgröße identifiziert werden. Hier wird die Normalspannung senkrecht zur Rissausbreitung, die sogenannte rissöffnende oder Mode I Spannung, als auszuwertende Beanspruchungsgröße empfohlen. Mit der Verwendung des Schädigungsparameters PRAM und unter Berücksichtigung der Stützwirkung entsprechend der FKM-Richtlinie nichtlinear ist eine zuverlässige Abschätzung des Versagensortes in der Fügeverbindung möglich. Für die Fügeverbindung aus dem Aluminiumblech EN AW-6181A ist mit dieser Methodik auch eine Lebensdauerabschätzung möglich. Für die Verbindungen, in denen das Aluminiumblech EN AW-6181A und das Stahlblech HX340LAD kombiniert werden, zeigt die Treffsicherheit jedoch noch erkennbares Verbesserungspotential. Die Gründe hierfür werden in Kapitel 7.2.5 und 7.2.6 beschrieben. Eine rechnerische Betriebsfestigkeitsauslegung ist mit Vorgehensweise 1 vergleichsweise einfach möglich. Jedoch sind entgegen des oben formulierten Ziels aufwendige Schwingversuche zur Bestimmung der Versagensbedingungen (Festigkeitswerte) notwendig. Dieser Nachteil kann umgangen werden, indem die Festigkeitsinformationen des einzelnen Fügepunktes unter verschiedenen Belastungsarten mithilfe von Vorgehensweise 2 ermittelt werden. Letztere wiederum eignet sich selbst nicht für eine Auslegung komplexer Bauteile mit mehreren Fügepunkten. Aufgrund der steigenden Berechnungsdauern der Simulation, ist die Anwendung in diesem Fall wirtschaftlich nicht sinnvoll. Durch die beschriebene Kombinationsmethode können die Nachteile der beiden einzelnen Konzepte kompensiert und eine rechnerische Betriebsfestigkeitsauslegung stanzgenieteter Bauteile basierend auf den zyklischen Werkstoffkennwerten durchgeführt werden. Das Ziel des Forschungsvorhabens wurde erreicht.

We investigate this potential and present playful user-generated treatment (PUT), a novel game-based approach for VRET. Based on a requirement analysis consisting of a literature review and semi-structured interviews with professional therapists, we designed and implemented the PUT concept as a two-step VR game design. To validate our approach, we conducted two studies. (1) In a study with 31 non-acrophobic subjects, we investigated the effect of content creation on player experience, motivation and height perception, and (2) in an online survey, we collected feedback from professional therapists. Both studies reveal that the PUT approach is well applicable. In particular, the analysis of the user study shows that the design phase leads to increased interest and enjoyment without notably influencing affective measures during the exposure session. Our work can help guiding researchers and practitioners at the intersection of game design and exposure therapy. author: - first_name: Dmitry full_name: Alexandrovsky, Dmitry last_name: Alexandrovsky - first_name: Georg full_name: Volkmar, Georg last_name: Volkmar - first_name: Maximilian full_name: Spliethöver, Maximilian id: '84035' last_name: Spliethöver orcid: 0000-0003-4364-1409 - first_name: Stefan full_name: Finke, Stefan last_name: Finke - first_name: Marc full_name: Herrlich, Marc last_name: Herrlich - first_name: Tanja full_name: Döring, Tanja last_name: Döring - first_name: Jan David full_name: Smeddinck, Jan David last_name: Smeddinck - first_name: Rainer full_name: Malaka, Rainer last_name: Malaka citation: ama: 'Alexandrovsky D, Volkmar G, Spliethöver M, et al.

Single metal ions or atoms are attractive candidates for the catalytic activation of non-reactive nitrogen (N2), and for future targeted improvement of NRR catalysts, it is of utmost importance to get detailed insights into structure-performance relationships and mechanisms of N2 activation in such structures. Here, we report density functional theory studies on the NRR catalyzed by single Au and Fe atoms supported in graphitic C2N materials. Our results show that the metal atoms present in the structure of C2N are the reactive sites, which catalyze the aforesaid reaction by strong adsorption and activation of N2. We further demonstrate that a lower onset electrode potential is required for Fe--C2N than for Au--C2N. Thus, Fe--C2N is theoretically predicted to be a potentially better NRR catalyst at ambient conditions than Au--C2N owing to the larger adsorption energy of N2 molecules. Furthermore, we have experimentally shown that single sites of Au and Fe supported on nitrogen-doped porous carbon are indeed active NRR catalysts. However, in contrast to our theoretical results, the Au-based catalyst performed slightly better with a Faradaic efficiency (FE) of 10.1{\%} than the Fe-based catalyst with an FE of 8.4{\%} at −0.2 V vs. RHE. The DFT calculations suggest that this difference is due to the competitive hydrogen evolution reaction and higher desorption energy of ammonia. author: - first_name: Sudhir K. full_name: Sahoo, Sudhir K. last_name: Sahoo - first_name: Julian Joachim full_name: Heske, Julian Joachim id: '53238' last_name: Heske - first_name: Markus full_name: Antonietti, Markus last_name: Antonietti - first_name: Qing full_name: Qin, Qing last_name: Qin - first_name: Martin full_name: Oschatz, Martin last_name: Oschatz - first_name: Thomas full_name: Kühne, Thomas id: '49079' last_name: Kühne citation: ama: Sahoo SK, Heske JJ, Antonietti M, Qin Q, Oschatz M, Kühne T.

It has a lasting influence on the perception of cultural identity as well as on the interactions between research, the cultural economy and society. Throughout the last three decades, many cultural heritage institutions have contributed a wealth of digital representations of cultural assets (2D digital reproductions of paintings, sheet music, 3D digital models of sculptures, monuments, rooms, buildings), audio-visual data (music, film, stage performances), and procedural research data such as encoding and annotation formats. The long-term preservation and FAIR availability of research data from the cultural heritage domain is fundamentally important, not only for future academic success in the humanities but also for the cultural identity of individuals and society as a whole. Up to now, no coordinated effort for professional research data management on a national level exists in Germany. NFDI4Culture aims to fill this gap and create a user-centered, research-driven infrastructure that will cover a broad range of research domains from musicology, art history and architecture to performance, theatre, film, and media studies.\r\n The research landscape addressed by the consortium is characterized by strong institutional differentiation. Research units in the consortium's community of interest comprise university institutes, art colleges, academies, galleries, libraries, archives and museums. This diverse landscape is also characterized by an abundance of research objects, methodologies and a great potential for data-driven research. In a unique effort carried out by the applicant and co-applicants of this proposal and ten academic societies, this community is interconnected for the first time through a federated approach that is ideally suited to the needs of the participating researchers. To promote collaboration within the NFDI, to share knowledge and technology and to provide extensive support for its users have been the guiding principles of the consortium from the beginning and will be at the heart of all workflows and decision-making processes. Thanks to these principles, NFDI4Culture has gathered strong support ranging from individual researchers to high-level cultural heritage organizations such as the UNESCO, the International Council of Museums, the Open Knowledge Foundation and Wikimedia. On this basis, NFDI4Culture will take innovative measures that promote a cultural change towards a more reflective and sustainable handling of research data and at the same time boost qualification and professionalization in data-driven research in the domain of cultural heritage. This will create a long-lasting impact on science, cultural economy and society as a whole." author: - first_name: Reinhard full_name: Altenhöner, Reinhard last_name: Altenhöner - first_name: Ina full_name: Blümel, Ina last_name: Blümel - first_name: Franziska full_name: Boehm, Franziska last_name: Boehm - first_name: Jens full_name: Bove, Jens last_name: Bove - first_name: Katrin full_name: Bicher, Katrin last_name: Bicher - first_name: Christian full_name: Bracht, Christian last_name: Bracht - first_name: Ortrun full_name: Brand, Ortrun last_name: Brand - first_name: Lisa full_name: Dieckmann, Lisa last_name: Dieckmann - first_name: Maria full_name: Effinger, Maria last_name: Effinger - first_name: Malte full_name: Hagener, Malte last_name: Hagener - first_name: Andrea full_name: Hammes, Andrea last_name: Hammes - first_name: Lambert full_name: Heller, Lambert last_name: Heller - first_name: Angela full_name: Kailus, Angela last_name: Kailus - first_name: Hubertus full_name: Kohle, Hubertus last_name: Kohle - first_name: Jens full_name: Ludwig, Jens last_name: Ludwig - first_name: Andreas full_name: Münzmay, Andreas last_name: Münzmay - first_name: Sarah full_name: Pittroff, Sarah last_name: Pittroff - first_name: Matthias full_name: Razum, Matthias last_name: Razum - first_name: Daniel full_name: Röwenstrunk, Daniel id: '439' last_name: Röwenstrunk orcid: https://orcid.org/0000-0001-6271-2095 - first_name: Harald full_name: Sack, Harald last_name: Sack - first_name: Holger full_name: Simon, Holger last_name: Simon - first_name: Dörte full_name: Schmidt, Dörte last_name: Schmidt - first_name: Torsten full_name: Schrade, Torsten last_name: Schrade - first_name: Annika-Valeska full_name: Walzel, Annika-Valeska last_name: Walzel - first_name: Barbara full_name: Wiermann, Barbara last_name: Wiermann citation: ama: Altenhöner R, Blümel I, Boehm F, et al.

Social media distrust affects the dissemination of disaster information as it entails shifts in media perception and participation but also changes in the way individuals and organisations make sense of information in critical situations. So far, a little considered notion in this domain is the concept of sense-giving. Originating from organisational theory, it is used to explain the mechanisms behind intentional information provision that fosters collective meaning creation. In our study, we seek to understand the potential impact of sense-giving from Twitter crisis communication generated during the Hurricane Harvey disaster event. Social network and content analyses performed with a dataset of 9,414,463 tweets yielded insights into how sense-giving occurs during a large-scale disaster event. Theoretically, we specified (1) perpetual sense-giving, which relies primarily on topical authority and frequency; as well as (2) intermittent sense-giving, which occurs from high value of message content and leverage of popularity, that is, retweets. Our findings emphasise the importance of information-rich actors in communication networks and the leverage of their influence in crises such as coronavirus disease 2019 to reduce social media distrust and facilitate sense-making. author: - first_name: Milad full_name: Mirbabaie, Milad id: '88691' last_name: Mirbabaie - first_name: Deborah full_name: Bunker, Deborah last_name: Bunker - first_name: Stefan full_name: Stieglitz, Stefan last_name: Stieglitz - first_name: Julian full_name: Marx, Julian last_name: Marx - first_name: Christian full_name: Ehnis, Christian last_name: Ehnis citation: ama: 'Mirbabaie M, Bunker D, Stieglitz S, Marx J, Ehnis C.

We decompose the online ratings by focusing on the customer’s decision-making process in a leading peer-to-peer ridesharing platform. Using data from the leading peer-to-peer ridesharing platform BlaBlaCar, we analyze 17,584 users registered between 2004 and 2014 and their online ratings focusing on the decomposition of the explicit determinants reflecting the variance of online ratings. We find clear evidence to suggest that a driver’s attitude towards music, pets, smoking, and conversation has a significantly positive influence on his received online ratings. However, we also show that the interaction of female drivers and their attitude towards pets has a significantly negative effect on average ratings. article_number: '6185' author: - first_name: Daniel full_name: Kaimann, Daniel id: '18949' last_name: Kaimann citation: ama: 'Kaimann D.
