This is particularly applicable to complex sociotechnical production environments with flexible material flows as well as undetermined events and fluctuations. Methods of optimization under uncertainty are very computationally intensive and crucial interactions with the real world are insufficiently considered. This lack of field synchronicity reduces the quality of production schedules, leads to manual efforts firefighting), and has a negative impact on the logistical performance. The present work is based on four journal articles that demonstrate novel methods and models for improving field-synchronous scheduling. Through the combination of instruments from operations research and machine learning, generic and predictive algorithms are developed to improve the efficiency and effectiveness of planning procedures. The findings suggest that regression models can replace computation-heavy stochastic simulations in obtaining robustness metrics. Additionally, using reinforcement learning, uncertainty-robust and realistic production schedules for human-centered manufacturing can be generated in a short time. For this purpose, discrete simulation models are used, which are data-driven initialized based on a general control logic. The algorithms can be integrated into a virtual factory, which serves as a digital representation of the real world and is the basis for smart and field-synchronous scheduling systems. In this context, a prototype distributed system for the planning of dynamic manufacturing processes can be presented, which is being tested by industry research partners and further developed in collaboration. Beyond the publications, further research needs can be derived. In order to ensure the transferability of the methods, they need to be evaluated in the context of additional and more comprehensive environments. From a scientific and practical perspective, it is a crucial challenge to develop holistic and proactive scheduling systems that orchestrate a comprehensive set of data-driven analysis and decision-making processes. In this regard, the presented methods and models need to be further developed and integrated into a generic overall concept. The work identifies four focus areas that future research should address in an interdisciplinary manner: (1) Generic simulation models, (2) Human-centered optimization, (3) Field-synchronous scheduling, and (4) System development and rollout.}, author = {Grumbach, Felix}, keywords = {Produktionsplanung und -steuerung, Operations Research, Machine Learning, Reinforcement Learning}, publisher = {Universitäts- und Landesbibliothek Sachsen-Anhalt}, title = {{Feldsynchrone Ablaufplanung dynamischer Fertigungsprozesse mit Techniken des maschinellen Lernens [kumulative Dissertation]}}, doi = {10.25673/115290}, year = {2024}, } @book{4434, author = {Eisfeld, Michael}, publisher = {Beuth}, title = {{BIM - Einstieg kompakt für Tragwerksplaner}}, year = {2024}, } @article{4403, author = {Hamilton, K. and Phipps, D.

As part of this work, various tests were carried out with crystalline modules from two different manufacturers. The modules had already been transported to a recycling company and were originally intended for recycling. The measurements carried out provide a comprehensive assessment of the condition of the PV modules. In total, five different measurement methods were used, two of which related to short-term measurements under controlled laboratory conditions and three to long-term assessments under real conditions. The investigation illustrated that modules from the recycling company have potential for reuse. However, it also showed that a clearly differentiated classification system is necessary due to module age- and environmental conditions-related degradation.

Über die Plattform „Hochschulkompass“ und Mitgliedsstudiengänge der Deutschen Gesellschaft für Public Health (DGPH) wurden 422 Studiengänge identifiziert.

Virtual reality (VR) in nursing education, as a digital element, is the subject of controversial debate. On one hand, it supports the authenticity of case studies by adding realistic perspectives and information. On the other hand, the costs of developing and maintaining software and hardware hinder its long-term implementation. Based in the German context, our aim is to promote the adoption of innovative digital methods in nursing education and to offer invaluable experiences from the field. Methods: In this paper, we describe our findings and insights from two different research projects focused on the incorporation of digital tools, particularly VR, into nursing education. Results: Starting with a brief recapitulation of the projects, we elucidate pedagogical strategies for embedding VR-driven scenarios in nursing education. Based on our experiences during the projects, we identify various positive aspects, such as changing perspective and simulating acute situations. Key findings: Although potential drawbacks remain, we advocate the long-term implementation and specific use of VR at the interface between theory and practice. Nevertheless, it is crucial to establish regular evaluation, observing the value of digitalisation, especially VR, for nursing education. }, author = {Pfeifer, Lydia Sophie and Fries, Sophia and Stirner, Alexander and Nagel, Lisa and Cohnen, Christian and Aschentrup, Leona and Schönbeck, Marleen and Nauerth, Annette and Raschper, Patrizia and Herzig, Tim Christian and Wrona, Kamil Joseph}, issn = {2039-4403}, journal = {Nursing Reports}, keywords = {virtual reality, 360-degree video, digital tools, nursing education, VR-driven scenarios, pedagogical strategies, digital methodologies, immersion, collaboration}, number = {1}, pages = {468--481}, publisher = {MDPI AG}, title = {{Positive Aspects and Potential Drawbacks of Implementing Digital Teaching/Learning Scenarios in Health Professions Using Nursing Education as an Example: A Research Report from Germany}}, doi = {10.3390/nursrep14010036}, volume = {14}, year = {2024}, } @inbook{4369, abstract = {Electrospinning can be used to prepare nanofiber mats from diverse polymers, polymer blends and embed-ded nanoparticles.
