Imagining the future beyond the crystal ball: Artificial Human Services here we come?
No full textThis special issue is focused on the topic of artificial intelligence in the field of human services. In addition to the importance and transformative potential of AI, the editorial presents in detail the areas of application, which range from case management, mental health, client support to administrative support and education. The special issue itself features three articles on AI technology in dementia care, AI in psychosocial support during natural disasters and LLM in mental health. The editorial also highlights important challenges related to data management, ethics, human rights and the need for an inclusive, human-centered design. The recommendations and future directions for further research emphasize the importance of interdisciplinary collaboration, ethical standards and stakeholder engagement, human-centered AI and data management to ensure responsible and effective integration and implementation of AI into human services
Ethical Considerations of AI in Education: A Case Study based on Pythia Learning Enhancement System
No full textAs the use of AI in education increases, addressing ethical concerns is essential for its responsible use and implementation. This study explores the ethical considerations of AI in education by analyzing a concrete application, the Pythia Learning Enhancement System, which enables personalized and adaptive educational experiences. In this case study, the concrete implementation of Pythia, contrary to high-level abstract analyses, provides practical insights into these ethical issues. To achieve this goal, we first define Pythia and outline its implementation. Using the various topics covered by Pythia, the ethical issues associated with each of these topics are outlined, resulting in a list of ten distinct ethical issues. Because there is overlap in issues covered by similar applications, they can benefit from this identification. An ethical (human rights) and didactic (constructivism) theoretical background is then provided as a basis for further discussion. This is used to build the arguments used in the main study. This consists of analyzing each of the issues and providing recommendations to mitigate potential harm arising from these issues. This helps to provide guidelines for future applications. In the analysis, the ethical discussion is mainly based on the human rights of the stakeholders involved, emphasizing human dignity. After the analysis, each of the issues is contextualized with the recent AI Act of the European Union, providing a novel mapping of the issues of AI in education to the AI Act. Finally, the limitations of the study are stated and a plan for future research is presented
EnEff:Wärme - FW-ZFSV 4_0 - Fernwärmeleitungsbau 4.0 mit zeitweise fließfähigen selbstverdichtenden Verfüllbaustoffen für niedrige und hohe Betriebstemperaturen : Abschlussbericht zum Verbundforschungsvorhaben
No full textDas dem Heft 68 zugrunde liegende Forschungsvorhaben „EnEff:Wärme: FW-ZFSV_4-0 - Fernwärmeleitungsbau 4.0 mit zeitweise fließfähigen selbstverdichtenden Verfüllbaustoffen für niedrige und hohe Betriebstemperaturen“ (FW-ZFSV 4.0) wurde im Rahmen des 7. Energieforschungsprogramms „Innovationen für die Energiewende“ vom Bundeswirtschaftsministerium für Energie und Klimaschutz über den Projektträger Jülich bewilligt und gefördert (FKZ 03EN3022). Die Bearbeitung erfolgte in einem Verbund aus AGFW-Projektgesellschaft für Rationalisierung, Information und Standardisierung mbH, der GEF Ingenieur AG, Leimen, der Ostbayerische Technische Hochschule Regensburg - Fakultät Bauingenieurwesen - Labor für Geotechnik, Regensburg und der HafenCity Universität Hamburg, Hamburg.
Ziel des Vorhabens FW-ZFSV 4.0 war es, für den Bereich der Fernwärme Hemmnisse aufzugreifen, praktisch und angewandt zu untersuchen und Antworten auf Fragen zu liefern, die in der Planung und Praxis noch den Einsatz der technisch für den Fernwärmeeinsatz gut erforschten ZFSV als Alternative zur üblichen Verfüllung und Bettung mit Sand verhindern. Darunter fällt insbesondere die Absicherung des Langzeitverhaltens durch Untersuchungen in situ, die Ermöglichung der EDV-gestützten statischen Berechnung sowie die Beantwortung offener organisatorischer und genehmigungsrechtlicher Fragen.
Mit den ausführlich dargestellten Projektergebnissen zu den oben genannten Themen sowie darüber hinaus ist es zukünftig möglich, ZFSV im Fernwärmeleitungsbau stark vereinfacht und sicher einzusetzen.
Aus Sicht des Projektkonsortiums steht mit ZFSV ein weiteres, generell abgesichertes Bettungsverfahren für insbesondere Kunststoffmantelrohre (als dominierendes System in der Fernwärme) als Alternative zur Verfüllung mit Sand zur Verfügung, das in Zukunft hoffentlich umfangreiche Anwendung findet.
Gleichzeitig wird damit und dadurch den allgemein bekannten Potenzialen von ZFSV bei der Bautechnik, der möglichen Kostenreduktion, der Reduktion des Einflusses von Baumaßnahmen auf Umgebung und Umwelt sowie bei der Ressourcenschonung weiter der Weg in der netzgebundenen Wärmeversorgung bereitet. Dies ist auch von erheblicher Bedeutung, da sich während der Projektlaufzeit gezeigt hat, dass sich die Anforderungen der Kreislaufwirtschaft an die Zulässigkeit natürlicher Rohstoffe wie Sand als Verfüllmaterial (Stichwort: Ersatzbaustoffverordnung) sowie die Konkurrenz um Sand als Rohstoff aktuell und zukünftig verschärfen
Eccentric partial compression tests on wall test specimens
No full textWithin the scope of this work, the objective was to transfer the stress situations resulting at the exterior wall-floor joint as partial area loads to wall test specimens. The actual load-bearing capacities of highly thermally insulating plane clay unit masonry are to be quantified and compared with the calculated load-bearing capacities based on the unconfined stress-strain relationship and the linear-elastic, quasi-ductile and rigid-plastic material behaviour. In order to record also the deformations and compression at cross-section level directly in the load application area as well as the curvatures at system level, the deformations of all test specimens are documented by means of optical deformation measurement (digital image correlation). In this way, not only the load-bearing capacity but also, in particular, the stress resp. Strain distribution and stress redistributions as well as the experimental moment-curvature relationship can be quantified for the further analytical considerations and evaluations. Accordingly, it can be determined for all eccentric partial area loads that, regardless of the loading situation, higher load bearing capacities are achieved both compared to the calculated bearing capacity and based on a rigid-plastic material behaviour. Especially in the case of the loading situation at the bottom of the walls with partially supported floors, the activation of the unloaded cross-sectional zone at the load transfer can be shown very well based on the photogrammetrically determined cross-sectional compression. The decoupling initiated by the local discontinuity of the stress-strain state occurs only after the rigid-plastic cross-sectional bearing capacity is reached
Towards AI-enhanced facade planning : integrating human expertise with machine learning-driven parametric modeling
No full textPlanning modern facade systems is complex, requiring optimization across multiple domains.This paper proposes an AI-enhanced workflow for facade planning, harnessing computer vision and human input via a Large Language Model.A generative AI system then guides a parametric model to produce 3D facade designs. Automated checks provide feedback to a Reinforcement Learning system, to iteratively determine optimal solutions.These solutions are verified and finalized by human expertise, ensuring improved outcomes with reduce planning time and effort.The approach illustrates how combining advanced AI methods with human expertise can address the multifactorial challenges of facade design within current industry practices
Integration and usage of simulation-based digital twins in internal logistics systems
No full textThis paper presents the workflows of Digital Twins in practice, with reference to three case studies. The objective is to present the processing of data and information flow. The most essential requirements for the design of a Digital Twin are synthesized from the case studies and a layer model is presented, which was developed based on the three case studies. The model consists of four functional layers and an overarching data- and workflow-management-backbone. A front-end layer is proposed for communication with the end user
