To reduce the time and cost associated with extensive experimental investigations, numerical modeling strategies are increasingly applied. In this numerical study, a further step in the modelling strategy for the direct pin-pressing (DPP) process of cFRTP and metal sheets is presented. The study focuses on modeling and simulating the occurring deformation mechanisms of decomposition, compaction, and separation of individual rovings on the mesoscale to analyze the resulting material structure. For this purpose, two simplified models were derived. The textile architecture is represented based on micrographs of cross-sections and discretized using the finite element method. The deformation of individual rovings during joining leads to a deformation of their initial elliptical cross section. To capture this level of resolution, both a cohesive zone and a pure contact approach are applied within the rovings. The highly viscous thermoplastic melt is modeled as a fluid employing the Arbitrary Lagrange–Eulerian (ALE) method. Matrix and roving meshes are coupled to account for fluid–structure interaction (FSI) during process. The study shows that coupling of matrix and rovings is necessary to obtain more accurate predictions of the deformation behaviour. Furthermore, the cohesive zone approach is better suited to simulate the emerging deformation mechanisms.</jats:p>"}],"publication":"Key Engineering Materials","doi":"10.4028/p-e8wywr","language":[{"iso":"eng"}],"date_updated":"2026-05-07T15:10:16Z","publication_status":"published","intvolume":"      1050","year":"2026","title":"Modelling Deformation Mechanisms Decomposition, Separation and Compaction in Mechanical Joining Processes of Fiber Reinforced Thermoplastics on Meso Scale","author":[{"full_name":"Gröger, Benjamin","first_name":"Benjamin","last_name":"Gröger"},{"id":"105344","orcid":"0000-0002-0169-8602","last_name":"Gerritzen","first_name":"Johannes","full_name":"Gerritzen, Johannes"},{"full_name":"Hornig, Andreas","first_name":"Andreas","last_name":"Hornig"},{"last_name":"Gude","first_name":"Maik","full_name":"Gude, Maik"}],"publication_identifier":{"issn":["1662-9795"]}},{"publication":"arXiv:2602.04464","abstract":[{"text":"Grocery retailers frequently apply price discounts to stimulate demand for expiring perishables. However, integrating these discounted sales into future demand forecasts presents a significant challenge. This study investigates the effectiveness of incorporating a fixed share of these sales as \\textit{regular} demand into the forecast, as commonly applied in practice. We employ a two-step regression approach on data from a major European grocery retailer, covering over 1,700 products across 676 stores. We reveal that forecasts underestimate actual demand for most SKUs when discounted sales occur. This residual uplift effect is significantly influenced by the number of sales at reduced prices. Our findings underscore the necessity for more precise approaches to integrate discounted sales into demand forecasts, thereby preventing excess inventory and the associated economic and environmental impacts of spoilage in the grocery sector.","lang":"eng"}],"file":[{"date_created":"2026-03-02T13:01:09Z","creator":"jbrenker","file_id":"64811","content_type":"application/pdf","success":1,"relation":"main_file","date_updated":"2026-03-02T13:01:09Z","file_name":"2602.04464v1.pdf","access_level":"closed","file_size":258211}],"date_created":"2026-03-02T13:00:32Z","type":"preprint","title":"Discounted Sales of Expiring Perishables: Challenges for Demand Forecasting in Grocery Retail Practice","year":"2026","author":[{"last_name":"Winkelmann","first_name":"David","full_name":"Winkelmann, David"},{"first_name":"Theresa","last_name":"Elbracht","full_name":"Elbracht, Theresa"},{"first_name":"Jonas Maximilian","last_name":"Brenker","full_name":"Brenker, Jonas Maximilian","id":"122957"},{"full_name":"Gerzen, Arnold","last_name":"Gerzen","first_name":"Arnold"}],"publication_status":"published","date_updated":"2026-05-07T15:29:50Z","main_file_link":[{"url":"https://arxiv.org/pdf/2602.04464","open_access":"1"}],"language":[{"iso":"eng"}],"file_date_updated":"2026-03-02T13:01:09Z","citation":{"chicago":"Winkelmann, David, Theresa Elbracht, Jonas Maximilian Brenker, and Arnold Gerzen. “Discounted Sales of Expiring Perishables: Challenges for Demand Forecasting in Grocery Retail Practice.” <i>ArXiv:2602.04464</i>. arXiv, 2026.","short":"D.

Especially, artificial intelligence (AI) is increasingly integrated into these ecosystems, so that they comprise non-human participants (e.g., AI-based chatbots)—fundamentally altering the nature of value (co-)creation. While existing literature examines human-to-human interactions, knowledge of service interactions between human actors and AI-based systems is still underexplored. To address this research gap, we develop a taxonomy, comprising six iterations, that explores the peculiarities of AI as either a resource or a (non-human) agent in digital service ecosystems. We evaluate our taxonomy using a multiple case study and derive the four archetypes of AI in digital service ecosystems: (1) discriminative experience enhancer, (2) protective ecosystem orchestrator, (3) ecosystem innovation companion, and (4) personalized service composer. Our results extend the knowledge on service science by showing how AI-based systems—discriminative or generative, and focusing on the interaction in the ecosystem or the individual service encounter—assume the role of resources and non-human agents. Researchers and practitioners can utilize our results to augment their ecosystems with AI.</jats:p>"}],"date_created":"2026-03-07T12:45:48Z","type":"journal_article"},{"type":"journal_article","oa":"1","date_created":"2026-05-09T14:31:59Z","publication":"Behaviour & Information Technology","citation":{"short":"P.

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.

However, in such photonic integrated circuits (PICs), the photonic components are placed very close to each other on the chip, resulting in thermal crosstalk which degrades the system performance. Air-filled oxide and deep trench designs have proven to be very effective in mitigating the thermal crosstalk for various frequently deployed photonic devices like Mach-Zehnder modulators (MZMs), ring resonators, optical switches, and photodetectors designed on a standard silicon-on-insulator (SOI) platform.

Furthermore, when advancing to the simulation of systems like fully integrated electronic transmit and receive frontends or photonically assisted analogue-to-digital converters (ADCs), it is up to the designer to find a suitable level of abstraction.

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.</jats:p>"}],"publication":"e-Journal of Nondestructive Testing","issue":"3","type":"conference","date_created":"2026-05-07T08:46:18Z","intvolume":"        31","publication_status":"published","date_updated":"2026-05-12T11:54:07Z","author":[{"first_name":"Alrik","last_name":"Dargel","full_name":"Dargel, Alrik"},{"last_name":"Troschitz","first_name":"Juliane","full_name":"Troschitz, Juliane"},{"first_name":"Maik","last_name":"Gude","full_name":"Gude, Maik"},{"last_name":"Kupfer","first_name":"Robert","full_name":"Kupfer, Robert"}],"publication_identifier":{"issn":["1435-4934"]},"year":"2026","title":"In-situ CT of Viscoelastic Plastic Materials: A Radiography-Based Lead Time Determination for Composite–Metal Joints at Elevated Temperature","doi":"10.58286/32601","language":[{"iso":"eng"}],"main_file_link":[{"url":"https://www.ndt.net/search/docs.php3?id=32601"}],"project":[{"name":"TRR 285 - Subproject C04","_id":"148"},{"_id":"133","name":"TRR 285 - Project Area C"},{"_id":"130","name":"TRR 285:  Methodenentwicklung zur mechanischen Fügbarkeit in wandlungsfähigen Prozessketten"}],"citation":{"apa":"Dargel, A., Troschitz, J., Gude, M., &#38; Kupfer, R.

Reuleaux triangle shaped clinched joints, in particular, show pronounced in-plane anisotropy depending on their orientation. While such effects have been studied at joint and specimen scale, their relevance at the structural level remains largely unexplored. 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.</jats:p>","lang":"eng"}],"date_created":"2026-04-22T08:19:27Z","type":"conference","department":[{"_id":"149"},{"_id":"321"},{"_id":"9"}]}]
