Ziel ist es, Studierenden eine zeitlich und örtlich flexible Möglichkeit zu bieten, den realitätsnahen Umgang mit Laborgeräten - primär dem Oszilloskop - zu erlernen. Die methodische Grundlage bilden der Makrozyklus von Design-Based Research (DBR) als strukturierender Rahmen und das heuristische Modell des Research Pentagons, das die Durchführung auf Mikroebene bestimmt. In insgesamt vier Research Pentagons werden didaktische, technologische, motivationale und evaluative Komponenten systematisch untersucht und weiterentwickelt. Das erste Pentagon fokussiert die Entwicklung eines didaktisch fundierten Konzepts nach dem Prinzip des Constructive Alignment, das Lernziele, Lernaktivitäten und Prüfungsformen in fünf abgestufte Lernlevel überführt. Diese reichen von der initialen Orientierung bis zur eigenständigen Problemlösung in einem freien Experimentiermodus. Im zweiten Research Pentagon wird die technische Machbarkeit von Augmented - und Virtual Reality (VR) im Laborumfeld anhand mehrerer funktionaler Prototypen evaluiert. Während sich VR aufgrund technischer Einschränkungen als ungeeignet erweist, zeigt AR - insbesondere in der markerlosen Ausführung mittels der Software Development Kits (SDKs) ARCore und ARKit - ein hohes Potenzial für den praktischen Einsatz. Im dritten Pentagon entsteht ein Onboarding-Modul, das auf die erste Version der mobilen App (V0.17.01) aufsetzt und grundlegende Funktionen eines realen Oszilloskops digital abbildet. Dabei werden Nutzer:innen schrittweise an das virtuelle Oszilloskop herangeführt und lernen zugleich die zentralen Funktionen der mAR-App kennen. Die Ergebnisse zeigen eine insgesamt neutrale bis leicht positive Nutzungserfahrung, wobei technische Schwächen (z.B. Reaktionszeit oder Objektverankerung) die Effizienz und Steuerbarkeit beeinträchtigen. Im Exkurs-Kapitel erfolgt eine Eye-Tracking-Studie zur Untersuchung visueller Aufmerksamkeit und individueller Lösungsstrategien von Expert:innen und Noviz:innen bei der Arbeit am realen Oszilloskop. Heatmaps und Zeitverläufe in definierten Areas of Interest (AOI) liefern erste Hinweise auf Unterschiede im Blickverhalten zwischen den Gruppen. Die algorithmischen Scanpfadanalysen der Blickverläufe hingegen zeigen eine geringe Trennschärfe. Das Potenzial von Eye-Tracking als Evaluationsmethode wird daher kritisch reflektiert, aber angesichts technologischer Entwicklungen und verfügbarer Eye-Tracker in Mixed Reality (MR) Brillen weiterhin als zukunftsrelevant eingeordnet. Die abschließende summative Evaluation nutzt ein Prä‑Post-Test-Design mit Kontrollgruppenvergleich mit 70 Teilnehmenden, um die Lernwirksamkeit der überarbeiteten mAR-App mit klassischen Materialien wie Videos und Handbüchern zu vergleichen. In der Interventionsgruppe (IG) zeigen sich auf kognitiver und affektiver Ebene signifikant positive Veränderungen: Die Leistungen steigen deutlich, insbesondere in den Taxonomiestufen Anwendung, Verständnis und Analyse; zugleich nehmen experimentelles Selbstkonzept und experimentelles Sachinteresse zu, während Überforderung und Ängstlichkeit im Hinblick auf die Laborpraktika abnehmen. Als Einschränkung zeigt sich, dass die mAR-App keinen klaren Vorsprung gegenüber der Kontrollgruppe (KG) erreicht, was sowohl auf die sehr gut ausgearbeiteten Materialien und Videos der KG als auch auf technische Begrenzungen der mobilen Umsetzung zurückzuführen ist: Kleine Displays, 2D-Oberflächen für 3D-Geräte und unpräzise Touch-Interaktionen erschweren komplexe, feinmotorische Aufgaben. In den begleitenden User Interface (UI) und User Experience (UX) Fragebögen spiegeln sich diese Limitationen in gemischten Bewertungen der App wider. Die Arbeit verdeutlicht, dass die mobile AR-Anwendung trotz technischer Einschränkungen wertvolle Möglichkeiten für die Vorbereitung auf Laborpraktika und das Kennenlernen von Laborgeräten bieten kann. Der Fokus bei der Entwicklung liegt von Beginn an auf einer modularen und flexiblen App-Architektur, um sie mit neuen Geräten und Aufgaben zu erweitern. Der Hauptnutzen liegt perspektivisch nicht in der mobilen Anwendung selbst, sondern in der strategischen Ausrichtung auf zukunftsfähige, skalierbare Lösungen für MR-Brillen. Diese erlauben eine authentische Gestensteuerung und realitätsnahe Interaktionen."},{"lang":"eng","text":"This thesis examines the development, testing, and evaluation of a mobile augmented reality application (mAR app), which is designed as a preparation tool for electrical engineering laboratory courses. The aim is to offer students an opportunity to work with laboratory equipment - primarily the oscilloscope - realistically without location and time constraints. The methodological basis is formed by the macrocycle of design-based research (DBR) as a structured framework and the heuristic model of the research pentagon, which specifies the implementation at the micro level. Didactic, technological, motivational, and evaluative components are systematically examined and further developed in a total of four research pentagons. The first pentagon focuses on the development of a didactically sound concept based on the principle of constructive alignment, which incorporates learning objectives, learning activities, and forms of assessment into five graduated learning levels. These range from initial orientation to independent problem-solving in a free experimentation mode. The second phase evaluates the technical feasibility of augmented and virtual reality (VR) in the laboratory environment using several prototypes. While VR turns out to be unsuitable due to technical limitations, AR - especially in the markerless version using the ARCore and ARKit software development kits (SDKs) - shows great potential for everyday use. In the third research pentagon, an onboarding module is created based on the first version of the mobile app (V0.17.01), which digitally maps the basic functions of a real oscilloscope. During this process, users are introduced to the virtual oscilloscope and become familiar with the main functions of the mAR app. The results show an overall neutral to slightly positive user experience, although technical weaknesses (e.g., reaction time and object fixing) negatively impact efficiency and controllability. In the fourth research pentagon, an eye-tracking study is carried out to investigate visual attention and individual solution strategies of expert and novice users when working with real oscilloscopes. Heatmaps and time sequences in defined areas of interest (AOI) provide first indications of differences in gaze behavior between the groups. The algorithmic scan path analysis, on the other hand, reveals a low degree of differentiation. The potential of eye tracking as an evaluation method is therefore critically reflected, but it is still considered to be relevant for future studies in light of technological advancements and the availability of eye trackers in mixed reality (MR) glasses. The final summative evaluation is carried out in the way of a pre-post test design with 70 participants and compares the usage of traditional materials such as videos and manuals with the improved mAR app. In the intervention group (IG), significant improvements emerge on both cognitive and affective levels: performance increases particularly in the areas of application, understanding, and analysis, while experimental self-concept and subject-related interest rise and feelings of overload and anxiety regarding the lab courses decline. As a limitation, the mAR app does not yield a clear advantage over the control group (CG), which can be attributed both to the highly refined materials and videos used in the CG and to technical constraints inherent to the mobile implementation: small displays, 2D interfaces on 3D devices, and imprecise touch interaction limit complex, sensitive motor tasks. These limitations are also reflected in the accompanying user interface (UI) and user experience (UX) questionnaires, which indicate mixed app ratings. Both groups show significant learning gains - particularly in the areas of application, understanding, and analysis. However, a significant advantage of the mAR App cannot be proven. Affective characteristics such as experimental self-concept and general experimental interests increase in both groups, while the feeling of fear before conducting real laboratory work decreases. The app itself achieves average ratings in user interface (UI) and user experience (UX) questionnaires. The thesis demonstrates that, despite technical limitations, the mobile AR application can provide a valuable alternative for preparing students for laboratory courses and familiarizing them with laboratory equipment. From the very beginning, the primary goal during development was a modular and flexible app architecture that can be extended with new devices, tasks, and functions. The main benefit is not in the mobile application itself, but in the strategic direction of future-oriented and scalable solutions for MR glasses, which allow immersive and realistic gesture interactions."}]},{"abstract":[{"lang":"ger","text":"Elektronenenergieverlustspektroskopie (engl.

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."},{"text":"Electron energy-loss spectroscopy (EELS) is an advanced analytical technique in transmission electron microscopy, as it provides insights into material characteristics, such as electronic properties or elemental composition, at the atomic scale. The precision of every EELS analysis, however, is inherently limited by noises and blur. This thesis offers a comprehensive understanding of the noise, which is particularly valuable at low dwell times necessary for beam sensitive materials and for electron-matter interactions with low frequency of occurrence, where the noise dominates the measurement. Additionally, correlations encountered in the noise of an EELS measurement are described from both a theoretical and experimental perspective. These correlations are caused by a convolution of the noisy signal with the detector point spread function. Methods for characterizing key noise parameters of typical detectors are described, allowing the noise model to be tailored to any EELS detector. Ultimately, a novel deconvolution method enabling significant sharpening and denoising of EELS measurements is introduced and demonstrated. Its efficiency is further validated on both simulation and experimental data. The described advancement offered by the proposed deconvolution method enables the extension of current electron microscope capabilities, facilitating analysis that would be unfeasible with existing deconvolution techniques.","lang":"eng"}],"citation":{"chicago":"Zietlow, Christian.

Predefined phases are selected without restrictions in the order according to a multi-objective optimisation to adapt to the traffic as freely as possible. Initially, the system is tested in simulations and compared with existing methods and analysed afterwards for its effectiveness in a prototype commissioning in field tests. Results indicate high potentials for reducing emissions and waiting times, highlighting the system's value. However, further refinement is necessary for standard implementation. This comprehensive approach demonstrates advancements in traffic management technology, showcasing the potential for enhancing urban mobility and reducing environmental impact."}],"related_material":{"link":[{"relation":"confirmation","url":"https://ieeexplore.ieee.org/document/10919569"}]},"publication":"2024 IEEE 27th International Conference on Intelligent Transportation Systems (ITSC)","department":[{"_id":"153"}],"keyword":["MPC"],"type":"conference","date_created":"2025-03-24T08:57:08Z","intvolume":" 27","date_updated":"2026-04-29T08:49:46Z","publication_status":"published","publication_identifier":{"issn":["2153-0017"]},"author":[{"id":"36303","full_name":"Malena, Kevin","last_name":"Malena","first_name":"Kevin","orcid":"0000-0003-1183-4679"},{"last_name":"Link","first_name":"Christopher","full_name":"Link, Christopher","id":"38249"},{"id":"17793","first_name":"Sandra","last_name":"Gausemeier","full_name":"Gausemeier, Sandra"},{"full_name":"Trächtler, Ansgar","last_name":"Trächtler","first_name":"Ansgar","id":"552"}],"title":"Implementation and Results of a Multi-Stage Model Predictive Traffic Light Control System","year":"2025","doi":"10.1109/itsc58415.2024.10919569","language":[{"iso":"eng"}]},{"publication_status":"accepted","date_updated":"2026-04-29T14:27:08Z","status":"public","title":"Broadband Nyquist Pulse Generation on TFLN Platform for Integrated Quantum Source","year":"2025","author":[{"id":"13256","full_name":"Kress, Christian","first_name":"Christian","orcid":"0000-0002-4403-2237","last_name":"Kress"},{"full_name":"Mihaylov, Martin Miroslavov","last_name":"Mihaylov","first_name":"Martin Miroslavov","id":"42449"},{"id":"39217","full_name":"Schwabe, Tobias","last_name":"Schwabe","first_name":"Tobias"},{"last_name":"Silberhorn","first_name":"Christine","full_name":"Silberhorn, Christine","id":"26263"},{"full_name":"Scheytt, J.

In particular, the car body offers several opportunities for weight reduction. Multi-material designs are increasingly being applied to select the most suitable material for the respective load and ultimately achieve synergy effects. For example, aluminium castings are used at the nodes of a spaceframe body. Subsequently, these are joined with profiles to form the bodyshell. To join different materials mechanical joining techniques, such as semi-tubular self-piercing riveting, are deployed. According to the current state of the art, cracks occur in the aluminium castings during the mechanical joining process as a result of the high degree of deformation. Although the aluminium casting alloys of the AlSi-system exhibit low ductility, these alloys reveal excellent castability. In particular, the ability to cast thin structural parts is enabled by the low liquidus point of the near eutectic aluminium casting alloys.\r\nThis study addresses the mechanical joining properties of the near eutectic aluminium casting alloy AlSi12, depending on different microstructures. These are achieved by annealing processes and modifying agents. Through an adapted heat treatment, the previously lamellar morphology can be transformed into a globular morphology, which leads to increased ductility and prevents the formation of cracks during the self-piercing riveting (SPR). The joinability is investigated using different die geometries, whereas the joint formation is analysed regarding crack initiation. To evaluate the increased ductility, microstructural and mechanical tests are performed and finally, a microstructure-joinability correlation is established."}],"date_created":"2025-02-24T10:25:31Z","department":[{"_id":"43"},{"_id":"158"},{"_id":"157"},{"_id":"9"},{"_id":"321"}],"type":"journal_article","keyword":["aluminium","casting","microstructure","joinability","self-piercing riveting"],"author":[{"id":"32340","first_name":"Moritz","last_name":"Neuser","full_name":"Neuser, Moritz"},{"id":"44935","full_name":"Holtkamp, Pia Katharina","last_name":"Holtkamp","first_name":"Pia Katharina"},{"last_name":"Hoyer","first_name":"Kay-Peter","full_name":"Hoyer, Kay-Peter","id":"48411"},{"full_name":"Kappe, Fabian","last_name":"Kappe","first_name":"Fabian","id":"66459"},{"full_name":"Yildiz, Safak","first_name":"Safak","last_name":"Yildiz"},{"id":"7850","full_name":"Bobbert, Mathias","first_name":"Mathias","last_name":"Bobbert"},{"last_name":"Meschut","first_name":"Gerson","orcid":"0000-0002-2763-1246","full_name":"Meschut, Gerson","id":"32056"},{"id":"43720","first_name":"Mirko","last_name":"Schaper","full_name":"Schaper, Mirko"}],"title":"Mechanical properties and joinability of the near-eutectic aluminium casting alloy AlSi12","year":"2025","article_type":"original","date_updated":"2026-05-12T12:13:31Z","publication_status":"published","language":[{"iso":"eng"}],"doi":"10.1177/14644207251319922"},{"project":[{"name":"TRR 285 - A: TRR 285 - Project Area A","_id":"131"},{"_id":"138","name":"TRR 285 – A04: TRR 285 - Subproject A04"},{"name":"TRR 285 - C: TRR 285 - Project Area C","_id":"133"},{"_id":"146","name":"TRR 285 – C02: TRR 285 - Subproject C02"},{"name":"TRR 285: Methodenentwicklung zur mechanischen Fügbarkeit in wandlungsfähigen Prozessketten","_id":"130"}],"quality_controlled":"1","citation":{"bibtex":"@inproceedings{Lüder_Holtkamp_Wituschek_Bobbert_Meschut_Lechner_Schmale_2025, place={Millersville}, series={Sheet Metal 2025}, title={Analysis of the binding mechanisms depending on versatile process variants of self-piercing riveting}, volume={52}, DOI={10.21741/9781644903551-13}, booktitle={Materials Research Proceedings}, publisher={Materials Research Forum LLC}, author={Lüder, Stephan and Holtkamp, Pia Katharina and Wituschek, Simon and Bobbert, Mathias and Meschut, Gerson and Lechner, Michael and Schmale, Hans Christian}, editor={Meschut, Gerson and Bobbert, Mathias and Duflou, Joost and Fratini, Livan and Hagenah, Hinnerk and Martins, Paulo A.

To overcome the limitations of existing finite element tools, a modular Python framework has been developed to automate three-dimensional crack growth simulations. The program combines geometric reconstruction, adaptive remeshing, and the numerical evaluation of fracture mechanics parameters within a single, fully automated workflow. The framework builds on open-source components and remains solver-independent, enabling straightforward integration with commercial or research finite element codes. A dedicated sequence of modules performs all required steps, from mesh separation and crack insertion to local submodeling, stress and displacement mapping, and iterative crack-front update, without manual interaction. The methodology was verified using a mini-compact tension (Mini-CT) specimen as a benchmark case. The numerical results demonstrate the accurate reproduction of stress intensity factors and energy release rates while achieving high computational efficiency through localized refinement. The developed approach provides a robust basis for crack growth simulations of geometrically complex or residual stress-affected structures. Its high degree of automation and flexibility makes it particularly suited for analyzing cracks in clinched and riveted joints, supporting the predictive design and durability assessment of joined lightweight structures."}],"issue":"1","publication":"Applied Sciences","department":[{"_id":"9"},{"_id":"952"},{"_id":"321"}],"type":"journal_article","date_created":"2026-01-20T08:47:40Z","intvolume":" 16","date_updated":"2026-05-12T12:46:22Z","publication_status":"published","author":[{"first_name":"Sven","last_name":"Krome","full_name":"Krome, Sven","id":"57245"},{"full_name":"Duffe, Tobias","last_name":"Duffe","first_name":"Tobias","id":"41322"},{"id":"291","first_name":"Gunter","last_name":"Kullmer","full_name":"Kullmer, Gunter"},{"first_name":"Britta","last_name":"Schramm","full_name":"Schramm, Britta","id":"4668"},{"full_name":"Ostwald, Richard","last_name":"Ostwald","first_name":"Richard","orcid":"0000-0003-2147-8444","id":"106876"}],"publication_identifier":{"issn":["2076-3417"]},"title":"Validation and Verification of Novel Three-Dimensional Crack Growth Simulation Software GmshCrack3D","year":"2025","doi":"10.3390/app16010384","language":[{"iso":"eng"}],"article_number":"384"},{"popular_science":"1","publication":"Cibedo-Beiträge","citation":{"bibtex":"@article{Kokew_Al-Daghistani_2025, title={Bericht: Ressourcen für Resilienz in islamischer Tradition.

In the development of advanced lightweight automotive solutions, self-piercing riveting (SPR) offers the possibility of joining multi-material structures to fulfil a wide variety of requirements. With regard to the entire process chain, production-related pre-deformations of the parts to be joined can influence the geometric shape and load capacity of SPR joints. Various studies have investigated the influence of pre-stretched sheet materials, in the sense of pre-drawing processes, on the formation of SPR joints. The impact of pre-stretching sheet metals on the formation of their geometrical characteristics and the shear-tensile strength of SPR processes was observed [1]. Pre-rolled semi-finished products are also joined together in mixed material automotive structures, e.g. tailor rolled blanks. This work aims to investigate the influence of pre-rolled joining parts on the geometric formation and load-carrying capacity of SPR joints. For this purpose, sheets of metal are cold-formed using a rolling process to induce a defined strain-hardening state in the material and then joined in various combinations. As the degree of deformation increases, the rolling of samples can lead to minimal accumulation of damage in the sheet materials, which can influence the joint behaviour. The rolling process, as well as the subsequent joining process, are also investigated by FEM. The influence of pre-rolled semi-finished products on the strength of the SPR joints is investigated.","lang":"eng"}],"publication":"Materials Research Proceedings","type":"conference","department":[{"_id":"157"}],"date_created":"2025-05-13T06:54:20Z"}]
