This paper analyses temperature-specific waste heat potentials in automotive factories, distinguishing between vehicle assembly and component production. Waste heat sources are classified according to their integration feasibility, differentiating between directly usable heat and lower-temperature heat requiring upgrading via heat pumps. Using real-world operational data from eight automotive factories, waste heat potentials are quantified relative to site-specific heat demand. The results show that vehicle assembly factories exhibit relatively homogeneous shares of directly usable waste heat, while indirectly usable potentials vary strongly across sites, particularly in component manufacturing. To capture temporal utilisation constraints, a time-resolved case study is conducted for one vehicle assembly factory, combining hourly waste heat availability, internal heat demand and the load of an external district heating network. The dynamic analysis indicates that a substantial share of available waste heat can be utilised internally over the year, including periods of full internal heat coverage, while only limited surpluses remain available for external use. Overall, the findings underline the importance of factory-level, time-resolved analyses for identifying realistically utilisable waste heat shares and for supporting site-specific planning of waste heat integration under realistic constraints, thereby supporting the decarbonisation of industrial and urban thermal energy systems.}}, author = {{Berendes, Manuel and Dehning, Patrick and Schlüter, Alexander}}, booktitle = {{International Sustainable Energy Conference}}, editor = {{Fink, Christian and Brunner, Christoph}}, title = {{{Waste Heat Utilisation in Automotive Factories}}}, doi = {{https://doi.org/10.52825/isec.v2i}}, year = {{2026}}, } @unpublished{64871, author = {{Rahangdale, Praful}}, title = {{{Drinfeld correspondence in infinite dimensions}}}, year = {{2026}}, } @phdthesis{67280, abstract = {{Typische Prüfungsformate des bildungswissenschaftlichen Lehramtsstudiums berücksichtigen den performativen Bereich von Kompetenz bislang nur unzureichend.

We thus aimed to assess the association between dietary factors and estimated 10-year cardiovascular disease risk across diabetes subtypes in the German Diabetes Study (GDS). Participants with recent-onset diabetes and from the 5-year follow-up examination were combined (n=635, mean age 47.5±12.9 years, 60% male) and classified into diabetes subtypes. Subtypes with prevalence >10% were included in cross-sectional analyses: severe autoimmune diabetes (39%), mild obesity-related diabetes (31%), and mild age-related diabetes (30%). Carbohydrate quality parameters and adherence to dietary patterns were assessed from food frequency questionnaires. Differences in associations between these dietary factors and 10-year cardiovascular risk estimated by SCORE2-Diabetes across subtypes were examined using multivariable-adjusted linear regression models including an interaction term. In people with severe autoimmune diabetes, the overall and the healthful plant-based diet index were associated with lower estimated 10-year cardiovascular risk (ß [95% CI] -6.8 [-12.1; -1.2] and -8.8% [-14.0; -3.2] per 1-standard deviation increases, respectively), while these associations were not evident among the remaining two subtypes (p-value for interaction between subtypes <0.05).

In the context of dynamic mechanical systems, this enables the compensation of modeling inaccuracies that arise from simplifications, missing effects, or uncertain parameters. In this work, a hybrid model is used as a starting point, in which the discrepancy between simulation and measurement is learned and compensated by a data‐driven correction element. To integrate such models into commercial multibody simulation software like Adams or Simpack, the formulation is adapted to operate directly on the force level. This allows implementation via standard co‐simulation interfaces without modifying the system's differential equations or solvers. The method is demonstrated using a three‐mass oscillator with synthetic measurement data. Results show that the coupled simulation works reliably and that the hybrid model significantly improves accuracy while remaining compatible with established industrial simulation workflows.}}, author = {{Wohlleben, Meike Claudia and Linneweber, Jill Mercedes and Schütte, Jan and Sextro, Walter}}, issn = {{1617-7061}}, journal = {{Proceedings in Applied Mathematics and Mechanics}}, number = {{4}}, publisher = {{Wiley}}, title = {{{Enabling Hybrid Modeling in Commercial MBS Software: A Force‐Level Approach}}}, doi = {{10.1002/pamm.70215}}, volume = {{26}}, year = {{2026}}, } @inbook{62907, author = {{Fröhleke, Christoph and Habig, Sebastian and Fechner, Sabine}}, booktitle = {{Handlungsorientierung in der Ausbildung von Lehrkräften und pädagogischen Fachkräften}}, editor = {{Vogelsang, Christoph and Grotegut, Lea and Bruns, Julia and Riese, Josef and Fechner, Sabine}}, publisher = {{Waxmann}}, title = {{{Erfassung handlungsorientierter Kompetenzen im Chemiepraktikum - Inwiefern kann die Performanz von Lehramtsstudierenden bei Prozessentscheidungen diagnostiziert werden?}}}, year = {{2026}}, } @unpublished{67292, abstract = {{Classical shadows are an influential framework for compressing copies of a given quantum state $ρ$ into classical data $S$, enabling many properties of $ρ$ to be predicted from relatively few copies.
