TY - JOUR A1 - Griesbeck, Michael A1 - Alles, Martina A1 - Treistler, Anja T1 - Hybrid, kollaborativ, zukunftsorientiert: Das Labor für Gruppenarbeit an der TH Rosenheim JF - Die Hochschullehre N2 - Das Projekt HigHRoQ an der TH Rosenheim hat mit dem „Labor für hybride Gruppenarbeit“ einen innovativen Lehrraum geschaffen, der hybride Lehre didaktisch und technisch weiterentwickelt. Der Raum ermöglicht kollaboratives Lernen in gemischten Gruppen aus Präsenz- und Online-Teilnehmenden. Die begleitende Evaluation anhand des ICAP-Modells zeigt, dass insbesondere interaktives und konstruktives Lernen gefördert werden. Entwickelte Nutzungsszenarien veranschaulichen, wie sich das Potenzial der hybriden Ausstattung durch gezielte didaktische Konzepte ausschöpfen lässt. Die Lernumgebung stärkt zentrale Zukunftskompetenzen wie digitale Kollaboration und unterstützt eine flexible, inklusive Hochschullehre, die den Anforderungen einer zunehmend hybriden Arbeits- und Lernwelt gerecht wird.

T2 - MATHMOD 2025 (11th Vienna International Conference on Mathematical Modelling) N2 - To determine failure rates is a challenge, if there are only a few failures and a low failure rate should be checked. As an application example, we are interested in failure rates of electrical automotive components for automated/autonomous driving. Basically, three methods are common: (i) exploitation of field data, (ii) standardized handbooks with failure rates, e.g. the FIDES guide, and (iii) laboratory long term exposure tests. We discuss shortly the (dis)advantages of each method and focus on the statistics behind method (i). Moreover, our poster sketches how this can be applied to data as available in industry.

Fahrlehrer klagen über unvorbereitete Schüler, während Studien wie PISA den Leistungsabfall im Schulsystem zeigen. Becker kritisiert Ausreden, etwa schlechte Fahrschulen, und eine ideologiegetriebene Bildungspolitik, die Standards senkt. Er fordert, Jugendliche durch Positive Psychologie zu stärken – mit Resilienz, Motivation und Fokus –, um ihr Potenzial zu entfalten und die Wissensgesellschaft zu sichern.

Utilizing GPT4-o to analyze O&M reports of 5089 photovoltaic plants, we classified outages according to the affected components and the underlying origin, identifying the most frequent string fault causes. An approach employing CUSUM Charts is introduced to identify substring outages within PV systems effectively. The methodology utilizes fundamental field data that is commonly available in practice. A filtering approach, combined with the use of CUSUM control charts, minimizes false positives, ensuring that only consistent underperformance is flagged as an out-age. The methodology returns far fewer false positives and more stable error intervals for substring outages than a former monitoring approach. Overall, the study demonstrates a significant improvement in detecting substring outages. The advanced methodology enables more effective O&M for PV plants, where substring outages are reliably identified after a short detection time.

This cut-off size is much smaller than the typical distance to the nearest neighbour. In particular, for typical initial data, we show convergence of the Newtonian trajectories to the characteristics of the Vlasov-Poisson system. The proof is based on a Gronwall estimate for the maximal distance between the exact microscopic dynamics and the approximate mean-field dynamics. Thus our result leads to a derivation of the Vlasov-Poisson equation from the microscopic $N$-particle dynamics with force term arbitrary close to the physically relevant Coulomb force.

For the transformation from linear to CE, decision support tools and methods are needed to assess and promote CE for constructions. With regard to sustainable financial decisions, life cycle costing (LCC) is the preferred method. However, the LCC approaches and their application in CE research differ. Based on a systematic literature review, the relevance of refurbishment in operation, reuse, recycling and disposal at end-of-life (EoL) in LCC is assessed. As a result, LCC has gained relevance in the construction sector, but CE plays a subordinate role in LCC applications. Costs or benefits of CE are often neglected. However, some research have shown that refurbishment as well as reuse and recycling can outweigh higher initial cost over lifetime. The internalisation of environmental and social impacts or even benefits are also rare. In particular, there is a lack of research on how to internalise the environmental benefits of refurbishment, reuse and recycling or how to effectively incentivise higher CE efforts in LCC in order to encourage decision-making in construction towards CE.

Vertical (axial) and horizontal winding symmetries under group actions reveal distinguishable tuning regions and individual variation states therein. The model is applied to coils of prismatic (cylinder like) and truncated pyramidal (conical like) shape with edges forming a regular polygon as basis, and verified by numerical magnet field simulation.
