We review in particular our work on both time- and frequency-domain approaches and give an outlook on how these architectures can be extended to include further signal processing tasks such as equalization. Optically triggered track-and-hold amplifiers are reported with an equivalent jitter below 80 fs rms in a signal frequency range from 20 GHz to 70 GHz. Frequency-domain architectures implementing optical arbitrary waveform measurement up to signal bandwidths of 610 GHz are also shown. Finally, an architecture allowing the deserialization and equalization of PAM4 signals is introduced and modeled for operation in 400 Gb/s links.}}, author = {{Witzens, Jeremy and Drayss, Daniel and Fang, Dengyang and Moscoso Mártir, Alvaro and Müller, Juliana and Weizel, Maxim and Zazzi, Andrea and Freude, Wolfgang and Koos, Christian and Randel, Sebastian and Scheytt, J.

Scan start times are therefore commonly defined based on force relaxation or force-gradient criteria, although these signals do not directly quantify image-relevant specimen motion. In this work, a radiography-based approach is presented to estimate relaxation-induced motion via pixel shifts from projection images acquired prior to CT scans. These projection-based pixel shift estimates of relaxation-induced motion are related to scan-specific image blur observed in the reconstructed volumes. Thereby, a direct link between specimen motion during the scan and CT image quality is established. The method is demonstrated for thermo-mechanically loaded specimens with pronounced temperature-dependent material behaviour, where relaxation-induced motion persists over extended time scales. The results show that projection-based pixel shift estimation provides a physically meaningful and experimentally accessible basis for defining scan start criteria. CT acquisition can be initiated based on an allowable level of relaxation-induced motion, rather than waiting for mechanical equilibrium to be reached. The proposed approach therefore offers a direct, image-related framework for scan timing in in-situ CT experiments on time-dependent materials.}}, author = {{Dargel, Alrik and Troschitz, Juliane and Gude, Maik and Kupfer, Robert}}, booktitle = {{e-Journal of Nondestructive Testing}}, issn = {{1435-4934}}, number = {{3}}, publisher = {{NDT.net GmbH & Co.

In this work, the influence of joint orientation on the bending response of a joined structure is investigated using numerical simulations. A simplified joint replacement model based on the *CONSTRAINED_SPR2 point-connector formulation in LS-DYNA is employed, with parameters calibrated from previously obtained experimental force displacement data. A hat shaped profile structure subjected to three-point bending is analyzed in a parametric study considering variations in joint orientation, joint spacing, and profile geometry. The results show that joint orientation has little influence during the initial deformation phase but becomes increasingly significant at larger displacements, where joint behavior governs load transfer. Orientation dependent effects are found to influence the global force displacement response and local load redistribution among joints, with magnitudes comparable to those induced by changes in joint spacing and structural geometry. The findings confirm that joint orientation effects remain relevant at the structural level and should be considered in the design of structures assembled using non-rotationally symmetric clinched joints.}}, author = {{Devulapally, Deekshith Reddy and Tröster, Thomas}}, booktitle = {{Materials Science Forum}}, issn = {{1662-9752}}, pages = {{161--169}}, publisher = {{Trans Tech Publications, Ltd.}}, title = {{{A Numerical Study on the Mutual Influence of Joint Orientation and Component Geometry in Non-Rotationally Symmetric Clinched Joints}}}, doi = {{10.4028/p-0tiihi}}, volume = {{1185}}, year = {{2026}}, } @inbook{65610, author = {{Büker, Petra and Herding, Jana and Henke, Vanessa and Seifert, Anja and Velten, Katrin}}, booktitle = {{Transitions to School in the 21st Century.

To address this, this contribution proposes a novel hybrid workflow that combines knowledge- and data-based approaches. Relationships are categorized based on their knowledge quality and the need for a quantitative prediction. Well-established, generalizable relationships are formalized in an ontology as design guidelines (no quantification required) or SWRL rules (quantification required) to model expert knowledge. In contrast, hard-to-formalize or not-fully-understood relationships are treated with regression models for continuous or classification models for binary criteria. These approaches are combined in a generic user interface (GUI), where the ontology can be accessed using predefined SPARQL queries to select and adapt parameters using expert knowledge. These parameters are then used as input for the metamodels. The developed workflow is evaluated on two exemplary joining tasks to illustrate, how designers can retrieve similar prior joints, adapt parameters using the encoded design rules and predict resulting joint properties under varying process conditions. In summary, the combination of ontology and metamodels facilitates the transition of trial and error into an efficient, documentable design process.}}, author = {{Einwag, Jonathan-Markus and Wiemer, Maximilian and Wartzack, Sandro and Goetz, Stefan}}, issn = {{2731-6564}}, journal = {{Discover Mechanical Engineering}}, number = {{1}}, publisher = {{Springer Science and Business Media LLC}}, title = {{{A hybrid knowledge based and data based approach for efficient clinch joint design}}}, doi = {{10.1007/s44245-026-00230-x}}, volume = {{5}}, year = {{2026}}, } @article{65609, author = {{Bürgel, Christoph}}, journal = {{Fremdsprachen Lehren und Lernen (FLuL), 7-14 }}, title = {{{Zur Einführung in den Themenschwerpunkt Lexiko-Grammatik im Fremdsprachenunterricht}}}, year = {{2026}}, } @misc{65624, author = {{Peitz, Robin}}, title = {{{Einfluss von Misch-, Material- und Prozessparametern auf die Koaleszenz flammgeschützter Pulver im Lasersintern}}}, year = {{2026}}, } @article{65626, author = {{Skolik, Alexander Marcus and Kaltenpoth, Sascha Benjamin and Beverungen, Daniel and Müller, Oliver}}, issn = {{0306-4379}}, journal = {{Information Systems}}, publisher = {{Elsevier BV}}, title = {{{A modular large language model agent architecture for adaptive and autonomous process-aware execution}}}, doi = {{10.1016/j.is.2026.102748}}, year = {{2026}}, } @inproceedings{65625, author = {{Friesen, Olga and Hölscher, Jonas and Siegmund, Michael B.
