Dataspaces provide the infrastructure necessary to integrate heterogeneous data sources within an organization or ecosystem, enabling seamless data interaction and interoperability. In addition, data spaces strengthen data sovereignty through their decentralized nature, which enables organizations to effectively control and manage their data. However, challenges persist in managing the complexity and dynamic nature of dataspaces, requiring significant resources and technical expertise. The decentralized nature leads to a large and diverse number of stakeholders, who need to agree on the use and scope of a dataspace. Modeling is a common approach to cope with technical complexity and heterogeneous stakeholders. In this paper, we propose a version of SysML and a corresponding method that focus on the modelling of data spaces. We provide a dataspace modelling method to unify the understanding of dataspaces and scope among all stakeholders to simplify the design and development process.}}, author = {{Kulkarni, Pranav Jayant and Zerbin, Julian and Koldewey, Christian and Bernijazov, Ruslan and Dumitrescu, Roman}}, booktitle = {{2024 IEEE International Conference on Technology Management, Operations and Decisions (ICTMOD)}}, keywords = {{Dataspaces, Modelling, SysML, Gaia-X, System Specification}}, location = {{Sharjah, United Arab Emirates }}, publisher = {{IEEE}}, title = {{{Using SysML as a Modelling Language for Dataspaces}}}, doi = {{10.1109/ictmod63116.2024.10878227}}, year = {{2025}}, } @article{60017, author = {{Skolik, Alexander Marcus and zur Heiden, Philipp and Donner, Johannes Aurelius Tamino and Priefer, Jennifer}}, journal = {{ECIS 2025 Proceedings}}, location = {{Amman, Jordan}}, title = {{{Igniting Knowledge Management for Assistance Systems in Maintenance: A Method for Knowledge Gathering}}}, volume = {{2}}, year = {{2025}}, } @inbook{62304, author = {{Schotten, Sarah Theresa and Otto, Franziska and Kremer, H.-Hugo}}, booktitle = {{Jahrbuch der berufs- und wirtschaftspädagogischen Forschung 2025}}, editor = {{Kögler, K. and Kremer, H.-H. and Herkner, V.}}, isbn = {{9783847431329}}, pages = {{253}}, publisher = {{Barbara Budrich}}, title = {{{Geschlechterstereotype Selbstdarstellungen junger Frauen in der Ausbildungsvorbereitung}}}, year = {{2025}}, } @inproceedings{62115, author = {{Wiemann, Leon and Schroeder, Sascha and Halverscheid, Stefan}}, booktitle = {{Proceedings of the 48th Conference of the International Group for the Psychology of Mathematics Eduction: Research Reports, Vol. 2}}, editor = {{Cornejo, Claudia and Felmer, Patricio and Gómez, David M. and Dartnell, Pablo and Araya, Paulina and Peri, Armano and Randolph, Valeria}}, location = {{Santiago de Chile}}, pages = {{387--394}}, publisher = {{PME}}, title = {{{The Influence of Mathematical Achievement on the Development of Intuitive Probabilistic Reasoning in Lower Secondary School Students}}}, volume = {{2}}, year = {{2025}}, } @article{63744, abstract = {{Orbital angular momentum (OAM) modes are an important resource used in various branches of quantum science and technology due to their unique helical structure and countably infinite basis. Generating light that simultaneously carries high-order orbital angular momenta and exhibits quantum correlations is a challenging task. In this work, we present a theoretical approach to the generation of correlated Schmidt modes carrying OAM via parametric down-conversion (PDC) in cascaded nonlinear systems (nonlinear interferometers) pumped by Laguerre–Gaussian beams. We demonstrate how the number of generated modes and their population can be controlled by varying the pump parameters, the gain of the PDC process, and the distance between the crystals. We investigate the angular displacement measurement uncertainty of these interferometers and demonstrate that it can overcome the classical shot noise limit.}}, author = {{Scharwald, Dennis and Gehse, Lucas and Sharapova, Polina}}, issn = {{2378-0967}}, journal = {{APL Photonics}}, number = {{1}}, publisher = {{AIP Publishing}}, title = {{{Schmidt modes carrying orbital angular momentum generated by cascaded systems pumped with Laguerre–Gaussian beams}}}, doi = {{10.1063/5.0229802}}, volume = {{10}}, year = {{2025}}, } @inproceedings{63822, author = {{Wiemann, Leon}}, booktitle = {{Beiträge zum Mathematikunterricht 2025. 58.

EELS) ist eine fortgeschrittene Analysemethode der Transmissionselektronenmikroskopie, die auf atomarer Ebene Einblicke in Materialcharakteristika wie bspw. Eigenschaften des Elektronensystems oder der Materialzusammensetzung erlaubt. Die Genauigkeit jeder EELS-Analyse ist jedoch fundamental durch Rauschen und Unschärfe begrenzt. Diese Thesis beschreibt solche Rauschphänomene im Detail. Vor allem bei strahlempfindlichen Materialien, die kurze Bestrahlzeiten erfordern, aber auch bei Elektron-Materie-Wechselwirkungen mit geringer Auftrittshäufigkeit, ist eine solche Beschreibung notwendig, da das Rauschen solche Messungen dominiert. Zusätzlich spielen Korrelationen des Rauschens eine Rolle, die durch Faltung des verrauschten Signals mit der Punktspreizfunktion des Detektors entstehen und die sowohl theoretisch als auch experimentell beschrieben werden. Methoden zur Messung der wichtigsten Rauschparameter bei typischen Detektorsystemen werden vorgestellt und erlauben es, das Rauschmodel auf jeden beliebigen EELS-Detektor anzupassen. Eine neue Entfaltungsmethode wird vorgeschlagen, die EELS-Messungen schärft und entrauscht. Die Wirksamkeit dieser Methode wird an Simulations- und Experimentaldaten dargelegt. Hierbei wird gezeigt, dass die neue Methode signifikant bessere Ergebnisse liefert, als bisherige und somit eine Analyse von Messdaten auf einem Level ermöglicht, das die Möglichkeiten der Elektronenmikroskopie deutlich erweitert.}}, author = {{Zietlow, Christian}}, publisher = {{Universitätsbibliothek Paderborn}}, title = {{{A novel Lagrangian-based method for the deconvolution of electron energy-loss spectra}}}, doi = {{10.17619/UNIPB/1-2438}}, year = {{2025}}, } @article{63862, author = {{Leineweber, Jonas}}, issn = {{0556-8218}}, journal = {{Rheinisch-Westfälische Zeitschrift für Volkskunde}}, number = {{1}}, pages = {{189--204}}, publisher = {{Waxmann}}, title = {{{Forschungs- und Spannungsfeld Immaterielles Kulturerbe.
