Net Working Capital Simulation: Auswirkungen von Zahlungszielveränderungen auf Bilanz und Cashflow
(2025)
The electrification of public transport introduces significant challenges for battery electric bus (BEB) fleet operators and power grid operators. This paper investigates the potential of two charging optimization strategies to reduce peak power demand in a BEB depot in Vorarlberg, Austria. A heuristic algorithm and Mixed-Integer Linear Programming (MILP) are analyzed and
compared to a reference strategy representing uncoordinated charging. The study aims to minimize peak power demand while ensuring efficient use of charging infrastructure. The results demonstrate the effectiveness of intelligent charging management in addressing the challenges posed by BEB operations.
Die Abschlussarbeit „Mich schreibend erkunden“ behandelt die Grundlagen und Methoden der Integrativen Poesie- und Bibliotherapie. Diese Form der Therapie berücksichtigt körperliche, emotionale, geistige und soziale Faktoren und nutzt kreative Medien wie Poesie und Literatur zur Förderung von persönlichem Wachstum und Heilung. Ein zentraler Bestandteil ist das Modell der „Fünf Säulen (des Supports) der Identität“, das verschiedene Dimensionen der Identität umfasst. Der geplante Workshop für Studierende der Rehabilitationspsychologie integriert diese Elemente.
Canalization is an optical phenomenon that enables unidirectional light propagation without predefined waveguiding designs. Recently demonstrated using phonon polaritons in twisted van der Waals (vdW) layers of α-MoO3, it offers unprecedented possibilities for controlling light-matter interactions at the nanoscale. However, practical applications have been hindered by the complex sample fabrication of twisted stacks. In this work, we introduce a previously unexplored canalization phenomenon in a single-thin vdW layer (α-MoO3) interfaced with a substrate exhibiting a given negative permittivity. This enables a proof-of-concept application of polariton canalization: super-resolution nanoimaging (~λ0/220). Canalization-based imaging transcends conventional projection constraints, allowing the super-resolution images to be obtained at any desired location in the image plane. This versatility stems from the synergetic manipulation of three key parameters: incident frequency, rotation angle of the thin vdW layer, and thickness. Our results provide insights into the properties of canalization and constitute a seminal step toward multifaceted photonic applications, including imaging, data transmission, and ultracompact photonic integration.
This randomized, controlled trial evaluated the impact of plaque visualization combined with daily tasks on cardiovascular risk profile and included 240 participants with coronary arterial disease. The intervention group received the PreventiPlaque app during the 12-month study period in addition to standard care. The app contained daily tasks that promoted lifestyle modifications and adherence to prescribed medication. It included ultrasound images of participants´ individual carotid plaque, which were updated regularly. The impact of plaque visualization and personalized app usage was evaluated, using a change in the SCORE2 as a primary endpoint. In the intervention group, the SCORE2 was significantly lower after the study period (t(120) = 6.43, padj < 0.001, dRM = 0.58). This demonstrates the efficacy of the PreventiPlaque app in supporting lifestyle modifications and medication adherence. These findings suggest that personalized mHealth interventions in combination with visual risk communication are valuable tools in secondary prevention. Trial Registration: The study was registered at ClinicalTrials.gov under the identifier NCT05096637 on 27 October 2021 and was approved by the local ethics committee of the University of Duisburg-Essen (20-9157-BO).
