One focus is on the integration of industrial waste heat and the uncertainty of future waste heat sources as well as restrictions on the use of biomass. For that purpose, knowledge about the energy demand is necessary. In a first step it is shown how the demand around a heating network is estimated with spatial data and a load profile is generated. Local available heat sources are examined according to their suitability and their kind of integration in the heating network. As heat production from different units are optimised, the development of a simulation model will be presented. The simulation is based on the optimisation of the operational costs of the used technologies for heating supply. Different scenarios covering various technologies and economic assumptions are applied. The results show the levelized costs of heating as well as the ecological performance. A sensitivity analysis shows the importance of uncertainties for the economic assumptions.

Diese können zu Stress und ambivalenten Gefühlen bei Schwangeren führen, die einen starken Einfluss auf das Wohlbefinden und die Gesundheit von Mutter und Kind haben. Zur Förderung eines komplikationslosen Verlaufs der Schwangerschaft wird in der Forschungsliteratur die Stärkung der gesundheitlichen Ressourcen gefordert. Das Zürcher Ressourcen Modell (ZRM) ist ein ressourcenaktivierendes Selbstmanagementtraining, welches nach aktuellen Studienergebnissen die Gefühlsregulierung unterstützen und Stress reduzieren kann. Ziel dieser Studie war die erstmalige Wirksamkeitsprüfung des ZRM in der Schwangerschaft. Angenommen wurde, dass durch die Aktivierung der persönlichen Ressourcen der Schwangeren das Stresserleben reduziert und das subjektive Wohlbefinden gesteigert werden kann. Die Konstrukte „Stress“ und „Wohlbefinden“ wurden anhand von fünf psychometrischen Parametern operationalisiert. Durchgeführt wurde eine quasiexperimentelle unkontrollierte 6‑stündige Online-Interventionsstudie mit dem ZRM im Januar 2021 an N = 32 Schwangeren, basierend auf einem Prä-Post-Follow-up-Design. Zur Überprüfung der gebildeten Hypothesen wurden einfaktorielle Varianzanalysen (rmANOVAs) durchgeführt. Die 1-faktoriellen rmANOVAs ergaben, dass die ZRM-Intervention das Stresserleben allgemein und schwangerschaftsspezifisch sowie das Angsterleben signifikant senken konnte. Handlungsorientierung nach Misserfolg und emotionales Wohlbefinden konnten signifikant gesteigert werden. Hinsichtlich der subjektiven Vitalität ließ sich lediglich deskriptiv eine Steigerung der Werte verzeichnen. Die ZRM-Intervention erwies sich als wirksame Methode zur Optimierung der Stressbewältigung und Steigerung des Wohlbefindens während der Schwangerschaft. Es kann zielführend sein, das ZRM-Training als Ergänzung zur üblichen Geburtsvorbereitung einzusetzen.

A crucial parameter for VQAs is the depth of the variational ansatz used - the smaller the depth, the more amenable the ansatz is to near-term quantum hardware in that it gives the circuit a chance to be fully executed before the system decoheres. This potential for depth reduction has made VQAs a staple of Noisy Intermediate-Scale Quantum (NISQ)-era research. In this work, we show that approximating the optimal depth for a given VQA ansatz is intractable. Formally, we show that for any constant $\epsilon>0$, it is QCMA-hard to approximate the optimal depth of a VQA ansatz within multiplicative factor $N^{1-\epsilon}$, for $N$ denoting the encoding size of the VQA instance. (Here, Quantum Classical Merlin-Arthur (QCMA) is a quantum generalization of NP.) We then show that this hardness persists even in the "simpler" setting of QAOAs. To our knowledge, this yields the first natural QCMA-hard-to-approximate problems. To achieve these results, we bypass the need for a PCP theorem for QCMA by appealing to the disperser-based NP-hardness of approximation construction of [Umans, FOCS 1999].}}, author = {{Bittel, Lennart and Gharibian, Sevag and Kliesch, Martin}}, booktitle = {{Proceedings of the 38th Computational Complexity Conference (CCC)}}, number = {{34}}, pages = {{34:1--34:24}}, title = {{{The Optimal Depth of Variational Quantum Algorithms Is QCMA-Hard to Approximate}}}, doi = {{10.4230/LIPIcs.CCC.2023.34}}, volume = {{264}}, year = {{2023}}, } @inbook{45990, author = {{Müller, Inez}}, booktitle = {{Interkulturelle Konstellationen in Literaturwissenschaft und Literaturdidaktik.
