The method combines model-based and data-driven techniques to decompose ODDs into three key components: environmental, scenery, and dynamic elements. It then applies prompt engineering to generate ScenarioRunner scripts compatible with CARLA. The model-based component guides the LLM using structured prompts and a “Tree of Thoughts” strategy to outline the scenario, while a data-driven refinement process, drawing inspiration from red teaming, enhances the accuracy and robustness of the generated scripts over time. Experimental results show that while static components, such as weather and road layouts, are well captured, dynamic elements like vehicle and pedestrian behavior require further refinement. Overall, this approach not only reduces the manual effort involved in creating simulation scenarios but also identifies key challenges and opportunities for advancing safer and more adaptive autonomous driving systems.}}, author = {{Danso, Aaron Agyapong and Büker, Ulrich}}, booktitle = {{Electronics}}, issn = {{2079-9292 }}, keywords = {{large language models, generation, Operational Design Domain, autonomous vehicles, simulation, CARLA, ScenarioRunner, prompt-engineering, fine-tuning}}, number = {{16}}, pages = {{3177}}, publisher = {{MDPI}}, title = {{{Automated Generation of Test Scenarios for Autonomous Driving Using LLMs}}}, doi = {{10.3390/electronics14163177}}, volume = {{14}}, year = {{2025}}, } @misc{13218, author = {{Uhlstein, Finja}}, keywords = {{Corporate Design, Raumgestaltung, Co-Working-Space, CD, CI, Kreativwirtschaft}}, pages = {{50}}, publisher = {{Technische Hochschule Ostwestfalen-Lippe}}, title = {{{Kreativitätsförderung durch Raumgestaltung und Corporate Design: Konzeption eines Co-Working-Space in der Kreativwirtschaft}}}, year = {{2025}}, } @misc{13350, abstract = {{In einer humanzentrierten Kleinserien- und Einzelfertigung mit Werkstattorganisation verfügen Fertigungsmitarbeitende häufig über eine hohe Autonomie und Entscheidungsfreiheit.

Das webbasierte Tool myField soll es den Bürger*innen ermöglichen, im persönlichen Wohnumfeld projektorientierte Maßnahmen zur Erzeugung umweltschutzorientierter Energievorhaben zu projektieren und durch Simulations- und Eigenabschätzungsverfahren eine Optimierung solcher Projektideen vorzunehmen. myField bietet neben der computerspiel-ähnlichen 3D-Welt zusätzlich eine Cloud-Plattform zur Kommunikation kollaborativer Ideen und zur Vernetzung zwischen den Akteur*innen. myField wurde vom Forschungsschwerpunkt nextPlace der Technischen Hochschule Ostwestfalen-Lippe in Kooperation mit der Arbeitsgruppe GIS des Geografischen Instituts der Universität Bonn als interaktive Softwareapplikation auf Basis der Gaming-Engine Unity3D entwickelt. Die ersten Arbeitsschritte beinhalteten Literatur- und Software-Recherchen zur inhaltlichen Positionierung. Die Kernarbeit bestand aus der Programmierung des Software-Prototypen und der Implementierung amtlicher Geodateninfrastrukturen.

Therefore, we present a method that incorporates Hardware-in-the-Loop simulations where virtual components as models are coupled to real and experimental facilities in real time. By including experimental components, a higher validity can be obtained and the practical applicability of renewable energy scenario can be discussed more profoundly. In this paper, the considered energy system consists of an experimental biocatalytic methanation reactor, a real photovoltaic park, a regenerative fuel cell and short-term storage units to supply a residential district. A representative control sequence of the methanator is obtained by modeling the scenario as an optimal control problem. A first HIL simulation highlights that modifications of the instrumentation are required for a grid injection of the generated methane. The scientific approach can be applied to any energy system where some of the considered components are available as experimental or real facilities. Non-exisiting components are simply replaced by models. The presented approach helps to determine which parts or process parameters are crucial for the planed operation before the overall energy system is realized on a larger scale. (C) 2019 Elsevier Ltd.

This paper aims to demonstrate how a metamodel, generated on simulated data, adapts to the type of product and delivers the required quality and evaluation procedure. The metamodel guarantees the requested characteristics of the final product without the consultation of human expert knowledge. As proof of concept, a simple, well-documented task from the field of construction has been chosen. The estimation from of the metamodel will meet all safety requirements, is based on the individual input variables and is confirmed without expert interaction. Fast, reliable prediction models deriving from complex simulation models are indispensable conditions for direct digital manufacturing.
