TY - CHAP A1 - Huang, Wenfei A1 - Melzer, Matthias A1 - Dünnweber, Jan T1 - Optimizing Smart Retail by Experiment Using an Online AI Model Exploration Interface T2 - 2024 Winter Simulation Conference (WSC), 15-18 December 2024, Orlando, FL, USA N2 - Smart retail technologies save grocery store operators a lot of work. At the same time, these technologies produce valuable data for building sustainable and economical inventory management strategies. AI models can be trained for sales forecasting using the data. The forecasts support the provisioning of fresh food over the whole week and help reducing food waste. In this paper, we present a Web portal which we developed to allow grocery store operators experiments with AI models revealing interrelations between observed and anticipated customer behavior. Clickable diagrams facilitate the exploration of data sets combining historical data and synthetically generated data. Pricing and ordering can be adapted accordingly to the simulated forecasts. By means of a case study, we show that our simulations are not only useful for predicting future sales but for other smart retail tasks as well.

The core concept is a large distributed and hierarchical database that translates internet domain names into host addresses and other supplemental information. Name servers can serve millions of domains and usually have to answer thousands of requests per second. Because of their vital function for any internet service, domain name servers are regularly target of Denial-of-Service attacks, where millions of queries per second are used to overload the database system. This work describes an approach on how to achieve answer rates in this dimension with a single server built from low-cost commodity hardware.

The sensor measures electron emission without the need for phosphorus screens or scintillators as converters. However, in initial experiments, rather low field emission currents of several hundreds of nanoamperes per emitter already damaged the sensor surface, which altered the systems’ signal response over the measurement time. In consequence, we coated the CMOS sensor surface with a Cu layer for surface protection. In contrast to the original insulating surface, Cu is an excellent current- and heat-conductor, which avoids lens charging by providing a conductive path for incident electrons and has an improved heat dissipation capability. Measurements using a segmented field emission cathode with four individually addressable tips demonstrate a consistent correlation between the emission current and the sensor signal of the metal-coated image sensor. Furthermore, the characterization of a field emission array showed that single tip emission currents of up to 12 μA per tip are measurable without discernible damage effects of the sensor’s surface.

Today, additive manufacturing techniques are also used for this purpose, in particular for implant steels. Additively processed materials sometimes react differently to etching than conventionally processed ones. The use of etchants for contrasting the microstructure must therefore be adapted. Chemical etching using V2A etchant, Murakami, and anhydrous Kalling solutions, as well as electrochemical etching using nitric acid, sodium hydroxide, and oxalic acid were performed. Etched samples made of conventionally processed X2CrNi-Mo17-12-2 were compared to samples manufactured using selective laser melting and sintering, and the optimal contrast was developed in each case. It can be shown that the different etchants reveal different microstructural constituents and that etchants must therefore be selected as a function of the application. N2 - Korrosionsbeständige Edelstähle werden vielfältig in der Medizintechnik eingesetzt. Dabei werden insbesondere bei Implantat-Stählen heute auch additive Fertigungstechniken angewandt. Additiv verarbeitete Materialien reagieren teilweise anders beim Ätzen als konventionell verarbeitete, weshalb der Einsatz von Ätzmitteln zur Gefüge-Kontrastierung adaptiert werden muss. Es wurde sowohl chemisch mit V2A-Beize, Murakami- und wasserfreier Kalling-Lösung geätzt, als auch elektrochemisch mit Salpetersäure, Natronlauge und Oxalsäure. Geätzte Proben aus konventionell verarbeitetem X2CrNiMo17-12-2 wurden mit Proben verglichen, die mittels selektivem Laserschmelzen und -sintern hergestellt wurden, und die jeweils optimale Kontrastierung entwickelt. Es kann gezeigt werden, dass die unterschiedlichen Ätzmittel verschiedene Gefügebestandteile hervorheben und somit je nach Anwendungsfall das jeweilige Ätzmittel ausgewählt werden muss.

In this paper, we give a brief overview of the current state of quantum computing by highlighting challenges it poses and opportunities it offers to the NHEP community. Noisy intermediate-scale quantum (NISQ) computers, while limited by imperfections and small scale, may hold promise for near-term quantum advantages when coupled with co-designed quantum algorithms and special-purpose quantum processing units (QPUs). We explore various applications in NHEP, including quantum simulation, event classification, and realtime experiment control, emphasising the potential of variational quantum circuits and related techniques. To identify current interests of the community, we perform an analysis of recent literature in NHEP related to QC.

While there are many algorithmic primitives to perform the required calculations, all eventually lead to quantum gates operating on quantum bits, with an order as determined by the structure of the objective function and the properties of target hardware. When the structure of the problem representation is not aligned with structure and boundary conditions of the executing hardware, various overheads degrading the computation may arise, possibly negating any possible quantum advantage. Therefore, automatic transformations of problem representations play an important role in quantum computing when descriptions (semi-)targeted at humans must be cast into forms that can be executed on quantum computers. Mathematically equivalent formulations are known to result in substantially different non-functional properties depending on hardware, algorithm and detail properties of the problem. Given the current state of noisy intermediate-scale quantum (NISQ) hardware, these effects are considerably more pronounced than in classical computing. Likewise, efficiency of the transformation itself is relevant because possible quantum advantage may easily be eradicated by the overhead of transforming between representations. In this paper, we consider a specific class of higher-level representations, i.e. polynomial unconstrained binary optimisation problems, and devise novel automatic transformation mechanisms into widely used quadratic unconstrained binary optimisation problems that substantially improve efficiency and versatility over the state of the art. We also identify what influence factors of lower-level details can be abstracted away in the transformation process, and which details must be made available to higher-level abstractions.

Examples are moving points, that change position over time, or, as a more complex data type, moving regions that can also change shape. For moving regions to be practically usable, methods for creating those objects have to be provided. The prevailing method for 2-dimensional moving regions is to create an interpolation of two static regions. Since this is a non-trivial task, this is referred to as the "Region Interpolation Problem", which still can not be considered as solved, since several unsolved questions remain. This work strives to give an overview on the Region Interpolation Problem, discuss an extension to 3d and higher dimensions and to present and discuss solutions to address some of the remaining obstacles.

A 150 mm thick concrete floor and a 100 mm thick floating floor were measured in the floor transmission facility of the National Research Council Canada, i.e. without flanking sound transmission. In addition to the sound reduction index and the normalized impact sound pressure level, loss factors, radiation efficiencies, and mean squared velocities were recorded in the laboratory. The measured data is compared to established models of sound transmission. A focus is placed on the calculation model of ISO 12354-1 (Appendix B), which uses calculated radiation efficiencies and loss factors to predict the sound reduction index of heavy, homogeneous building elements. Some difficulties with the calculation model and the examples in the standard are discussed. In principle, the results in this study show that the calculation model of ISO 12354-1 gives good estimates when the correct input parameters are used. However, deviations between the calculated and the measured loss factors and radiation efficiencies have large effects on the accuracy of the estimates, particularly in the region around the coincidence frequency.

Following the general trend of decentralisation of control structure in the Industry 4.0 paradigm, this paper analyses the application of auction algorithms to solve the robot task assignment problem. We focus on the use of mobile robots in production environments with a high level of uncertainty which places hight demand on the flexibility of the online scheduling architecture. A sequential single-item (SSI) auction algorithm is validated for a real-world use case where multiple mobile robots supply car bodies to manual rework stations in a paint shop application using simulation.

Many manufacturing companies, which nowadays operate in a global production network, are heavily exposed to these disruptions. This results in both significant costs and substantial exceeding of promised deadlines. If it concerns the first company in a supply chain, it causes correspondingly significant delays in promised deadlines for subsequent companies in the supply chain, including a correspondingly significant increase in costs. Both are exemplified in this paper through a case study. This case study demonstrates that through resilience, both implications can be significantly reduced.

Um dieses Forschungsfeld thematisch zu strukturieren, eignet sich ein Scoping Review. Im Folgenden werden ausschließlich Ergebnisse präsentiert, die im Themenblock „Intensiv- und Beatmungspflege“ Erkenntnisse zu den zwei Forschungsfragen ergeben: 1. Welche Faktoren begünstigen die Lebensqualität bei beatmeten Menschen v.a. bei einer Versorgung im außerklinischen Setting? 2. Welche Faktoren forcieren das Weaning in einem außerklinischen Setting und unter welchen Bedingungen wirken sie? Methode Google Scholar, PubMed, CINAHL, CareLit, LIVIVO, Cochrane Library sowie Web of Science wurden mit vorab definierten Suchbegriffen durchsucht. Nach zwei Extraktionen verblieben 401 Treffer. Die Abstract-Sichtungen führten zu einer thematischen Bündelung. Im Themenblock „Intensiv- und Beatmungspflege“ wurden 120 Volltexte gesichtet. Ergebnisse Aus den Ergebnissen ist zu folgern, dass die Datenlage als wenig suffizient bewertet wird. Die Lebensqualität von dauerhaft beatmeten Menschen scheint sehr heterogen zu sein. Als positiv wirksam erweisen sich die Faktoren Selbstbestimmung, eine offene und empathische Kommunikation aller Beteiligten sowie das Eingebundensein der Patientinnen und Patienten in soziale Netzwerke. Zur Qualitätsgewährleistung ist eine hohe Fachkompetenz der Pflegekräfte nötig. Anhaltender Fachpersonalmangel wirkt sich qualitätsmindernd aus. Weaning-Potentiale werden bislang in der Außerklinik nicht ausreichend ausgeschöpft. Intersektorale Versorgungskonzepte werden diskutiert. Diskussion Die Themen der außerklinischen Intensivpflege sowie des Weanings sind auf Basis der Aspekte eines selbstbestimmten und zufriedenen Lebens kaum evaluiert. Was aber zur Lebensqualität und zur Selbstbestimmung beiträgt, ist noch kaum operationalisiert. Weitere Forschungsaktivitäten insbesondere mit Rücksicht auf die Betroffenensicht sind angezeigt, weil sich andeutet, dass gerade die Selbstbestimmung im Weaning-Prozess zur Lebensqualität der schwer erkrankten Menschen beiträgt. Background In 2021, a transitional form of housing for outpatient weaning has been certified based on paragraph 17 of the Bavarian Law on Quality Assurance of Care and Housing. In order to get an overview over the research field, a scoping review was carried out. In particular, two research questions were focussed: 1. Which factors are beneficial for the quality of life of people who have to receive artificial respiration in an outpatient setting? 2. Which factors enforce weaning in an outpatient setting and what are conditions facilitating weaning? Methods Seven data bases were searched with defined search terms. After two extractions, 401 matches were found. On the basis of an analysis of abstracts, the results were systematically categorized. In order to answer the research questions, the topic „intensive and respiration care“ were chosen for closer analysis. Consequently, 120 texts were analysed more thoroughly. Results Results show that we do not have sufficient data to answer the research questions in a satisfactory manner. The life quality of people that have to be ventilated is heterogenous. What clearly enhances the life quality of care patients is self-determination and empathetic communication of patients with the relevant institutions. What is also beneficial is the inclusion of patients in social networks. In order to guarantee quality in intensive outpatient care a highly competent care staff is needed. What is obviously negative is the lack of competent personnel. It was also observed that the weaning potentials in outpatient care are not sufficiently made use of. Intersectoral care concepts are being discussed. Discussion The issues of intensive outpatient care as well as weaning and the question of how a self-determined and satisfactory life can be achieved have hardly been evaluated. Moreover, what exactly is meant by life quality and self-determination has hardly been operationalized either. Further research is necessary. However, self-determination is a central concept contributing to the life quality of seriously ill patients.

Eine effektive Planung von Restrukturierungen in Produktionssystemen, oft als Umzugsplanung bezeichnet, ist entscheidend, um Verzögerungen zu vermeiden und Stillstandszeiten zu minimieren. Die Identifikation von Umzugsfällen, welche den Umfang umzuziehender Ressourcen wie Maschinen, Anlagen, Ausrüstungen und Arbeitsplätzen beschreiben und die Definition zugehöriger Aufgaben sind essenzielle Schritte der Umzugsplanung.

N2 - Given a dynamic industrial environment, manufacturing companies must remain flexible and continuously adapt to maintain their competitiveness. Effective planning of restructuring efforts in production systems, often referred to as reconfiguration planning, is crucial to avoid delays and minimize downtime. Identifying reconfiguration cases, which describe the scope of resources to be relocated, such as machines, equipment, and workstations, and defining the associated tasks are essential steps in reconfiguration planning. This paper presents an approach for determining reconfiguration cases using a factory data model, complemented by visualization in virtual reality, to support planners in the reconfiguration process.

Even if only specific companies were originally affected, shortages and delays rippled along the supply network. The established approach to deal with disruptions is to utilize safety stock and capacity to compensate for fluctuations in uncertain quantities like customer demand. This approach is tried and tested for small fluctuations. To address larger disruptions, like the above given, very high safety stock and capacity would be needed, which would lead to unnecessarily high costs. Resilience has often been viewed as an expensive capability that drives costs. Recent studies however advocate for the development of lean resilience concepts, creating new capabilities, which enable resilience and can deal with large fluctuations, reimagining resilience from the perspectives of efficiency and value creation. This contribution identifies gaps in current research and establishes structural deficits of approaches discussed in the literature regarding supply chains. Firstly, the need for rigorous, quantitative definitions of resilience and relevant disruptions is justified. Then, a stochastic model for aggregate production planning that includes capabilities to compensate for such large fluctuations along several dimensions is proposed. Lastly, this model is then applied to a case study pertaining to a realistic supply chain under the risk of large scale disruptions and the results of this approach are evaluated.

Jahrestagung der GfHf, 23.–25. September 2024, FernUniversität in Hagen N2 - Hintergrund Während Rekrutierungsaktivitäten für HAW-Professuren sowohl wissenschaftlich (z.B. Braun & Wilson, 2023) als auch im Zuge von Kampagnen (z.B. „Werden Sie Prof!“; „Die HAW-Professur“) in den Fokus rücken, findet die Personalentwicklung von bereits etablierten HAW-Professorinnen und -Professoren noch wenig Beachtung. Dies liegt auch daran, dass die fachliche und berufliche Weiterentwicklung oft in der Eigenverantwortung der Professorinnen/Professoren gesehen wird (Becker, 2020). Dabei können bis zur Pensionierung gut 25 Jahre im Beruf der HAW-Professur verbracht werden (durchschnittliches Alter bei Erstberufung nach eigener Erhebung: 40 Jahre). Über diesen Zeitraum gilt es, Arbeitsengagement und berufliche Zufriedenheit zu bewahren. Aus diesem Grund stellt sich die Frage, ob und wie eine Personalentwicklung wirken kann, um Leistung und Engagement nachhaltig aufrechtzuerhalten. Forschungsfrage Die HAW-Professur setzt eine ausgeprägte berufliche Kompetenz (Praxis-, Forschungs- und Lehrerfahrung) voraus und ermöglicht ein hohes Maß an Autonomie (Wilkesmann & Lauer, 2021). Sie bietet daher optimale Voraussetzungen, um psychologische Grundbedürfnisse im Sinne der Self-Determination Theory (Deci & Ryan, 2000) zu erfüllen, welche wiederum ein erfolgreiches Wirken in der Arbeit ermöglichen. Im Rahmen einer deutschlandweiten Befragung von HAW-Professorinnen und -Professoren wurde deshalb der Frage nachgegangen, inwieweit Autonomie- und Kompetenzwahrnehmung und das Zugehörigkeitsgefühl zur Hochschulgemeinschaft das Arbeitsengagement und die Zufriedenheit in der HAW-Professur fördern. Methodisches Vorgehen und Datengrundlage Über 700 HAW-Professorinnen und Professoren beteiligten sich an einer Online-Befragung zum Thema „Karrierewege und Selbstbestimmung“. Dabei wurden u.a. das Arbeitsengagement (Bakker & Schaufeli, 2015) und die Zufriedenheit (Bérubé et al.,2007) erfasst. In Anlehnung an die Self-Determination Theory (Deci & Ryan, 2000) wurden außerdem die Aspekte Autonomie- und Kompetenzwahrnehmung sowie soziale Eingebundenheit erhoben. Ergebnisse Die Studie liefert Hinweise, wie die Personalentwicklung für HAW-Professuren gestaltet werden kann, um Zufriedenheit und ein hohes Arbeitsengagement aufrechtzuerhalten. Sie lassen also Rückschlüsse auf die Gestaltung einer zielgerichteten und nachhaltigen Personalentwicklung zu. Diese Forschung wird mit Mitteln des Bundesministeriums für Bildung und Forschung und des Landes Bayern als Teil des Projekts Zukunft akademisches Personal der OTH Regensburg (ZAP.OTHR) unter dem Programm „FH-Personal“ gefördert.

Meanwhile, PROs are a component of the certification requirements of the German Cancer Society for oncology centers. PROs are used to provide supportive therapy. There is currently no instrument that fully covers the requirements. At the University Hospital Regensburg (UKR), a digital ONCOlogical-ROUTinE-Screening (ONCO-ROUTES) procedure was developed in order to assess the need for supportive therapy in a standardized way and to provide patients with supportive interventions tailored to their needs. Methods On the basis of current requirements and guidelines, the development of ONCO-ROUTES was supported by experts in focus groups and interviews, and digitalization was carried out in connection with the IT infrastructure. Results A Needs-based, Quality-of-life (QoL) and Symptoms Screening (NQS2) tool already established in the routine at the UKR was further developed into ONCO-ROUTES, which is made up of the domains therapy phase, nutrition, tobacco use, alcohol use, quality of life, general condition/functional status, physical activity, psychooncology, social services, and further support needs. By linking the digitized questionnaire to the hospital information system, the results are available for immediate use in routine operations and thus for the referral of patients for further supportive therapy. Conclusion The digital PRO application ONCO-ROUTES is designed to involve patients in monitoring additional supportive needs and thus, improves supportive interdisciplinary treatment.

Compared to its PCA-based predecessor, our model employs implicit neural representations; hence, it can be trained on raw 3D breast scans and eliminates the need for computationally demanding non-rigid registration -- a task that is particularly difficult for feature-less breast shapes. The resulting model, dubbed iRBSM, captures detailed surface geometry including fine structures such as nipples and belly buttons, is highly expressive, and outperforms the RBSM on different surface reconstruction tasks. Finally, leveraging the iRBSM, we present a prototype application to 3D reconstruct breast shapes from just a single image. Model and code publicly available at this https URL.

It is imperative for the Information Systems (IS) discipline to engage in addressing these challenges. This paper aims to contribute to this imperative through a scoping literature review, examining factors that enable IS executives to drive sustainability outcomes within organizations, utilizing the Input-Mediator-Outcome (IMO) framework. By analyzing 31 articles from important IS journals and conferences between 2008 and 2024, this review identifies key input factors for sustainability outcomes, such as individual IS executive inputs, the role of the Top Management Team (TMT) setting and organizational contexts, as well as external influences. In addition, it explores how team-specific processes can augment sustainability efforts. The paper concludes by proposing future research questions to address underrepresented SDGs, investigate external impact factors more thoroughly, and emphasize the role of individual IS executive inputs. These insights aspire to advance the understanding of IS executives’ potential to influence sustainability in organizational settings.

Novice researchers not only lack the experience to know when a particular hypothesis test is appropriate, but struggle to find suitable literature to familiarize themselves (i.e., literature that is not too superficial, yet comprehensible). With the present article we provide a remedy following the didactic method of scaffolding: We present a systematization of the most elementary inferential statistical methods, namely hypothesis tests for group differences. We start by explaining basic terms (e.g., independent variable) and then give step-by-step instructions for choosing a proper hypothesis test based on data properties, implementing it from scratch, and reporting or interpreting its results. With these practical cookbook-like guidelines, this article serves as a concise starting point for young researchers entering the field of empirical research, as a valuable resource for their instructors, and as a basis for automating statistical procedures in a software system.

This is especially true for data analysis – a task that usually requires knowledge from two distinct areas: statistics and programming. To support prospective researchers with that task, we developed a web-based tool called eyenalyzer. It supports common activities in the data analysis phase of empirical studies in a way that is suitable for novices in both, statistics and programming. The present article describes a controlled experiment investigating the impact of this tool with a total of 20 participants. All of them are given a set of common data analysis tasks. Half of the participants complete the tasks using eyenalyzer, the other half can use anything except for eyenalyzer. For each task and participant, we record the time in minutes, the task score, and the perceived difficulty. The results confirm that our tool is a valuable support for novice researchers: With eyenalyzer, the participants are significantly faster, achieve higher scores, and perceive the tasks to be less difficult.

This learner profile has various benefits, like adapting the learning content, promoting of self-reflection, or increasing motivation in learning and therefore better learning results. Some researchers take the results of such questionnaires as ground truth or trust them blindly. Examining how persistent questionnaires are, asking the same questions twice, and comparing the results is a way to prove or falsify this statement. Our research procedure compares the results of three different questionnaires. The first questionnaire is the ILS (index of learning styles) according to the Felder-Silverman Learning Style Model (FSLSM) with about 44 questions. Learning strategies are examined with the LIST-K questionnaire consisting of 39 questions after Klingsieck. The third and last questionnaire is about personality traits. With only ten questions, Rammstedt et al. describe the BFI-10 questionnaire for personality traits. To compare results, the same study with the three named questionnaires is carried out twice with three to four months in between. The sample includes 35 students in their bachelor studies taking the course Software Engineering in a blended learning format. After collecting the questionnaire data from the students, a comparison is made in two different ways. First, we compare the data points based on the given answers. Second, a comparison is made based on the calculated questionnaire results because each of the three questionnaires has its own analysis method. For example, the analysis method of the ILS delivers as a result four integers representing the four characteristics of a learning style, while LIST-K makes a factor analysis. The results of the paper show that both the given answers and the calculated questionnaire results differ. Not one student has given the same answer inside each questionnaire with causes, like a change of learning style, learning strategy, and personality traits, or not filling in conscientiously.

One reason seems to be the contact of blood with large artificial surfaces within the membrane lung (ML). The aim was to test the hemocompatibility of different naïve ECMO materials. Blood and platelets from five healthy volunteers were incubated with gas exchange (GF) and heat exchange fibers (HE) from four different commercial available new MLs representing different antithrombogenic coatings. Adherent platelets were stained with rhodamine-phalloidin. Surface coverage was quantified with ImageJ. Non-adherent platelets were stained with antibodies (CD62P, PAC-1, CD61) and fibrinogen to detect platelet activation with flow cytometry. Hemolysis of red blood cells after material contact was detected. All ECMO-materials were non-hemolytic and did not induce platelet activation. However, platetelet adhesion (median (IQR)) was significantly elevated on uncoated GFs made of polymethylpentene (GF-PMP; 12 (7-19)%) and on GFs from the Hilite-MLs (GF-Hilite; 13 ((8-19)%) compared to the other materials. In vitro testing of platelet adhesion disclosed significant differences of ECMO-materials with different antithrombogenic surface coatings. Instead, circulating platelets remained non-activated. ECMO-materials and its coatings were non-hemolytic. Finally, this study confirmed the good hemocompatibility of GFs and HEs from commerciall available MLs.

An important class of objects are moving regions that can change shape and position over time. Currently, the prevailing method for constructing moving regions is to interpolate them from snapshots. In this paper, an alternative method is proposed, that is better suitable for certain kinds of data as, for example, satellite scans of the earth surface. For instance, the NASA provides datasets with active fire data in near real-time from the Visible Infrared Imaging Radiometer Suite (VIIRS) sensor, attached to satellites as the Suomi NPP and NOAA-20. These satellites orbit earth about 14 times a day and provide full global coverage twice a day. Using these satellites, datasets are compiled that provide locations of active fires on earth as lists of positions and timestamps. This paper describes an alternative, better suitable method for creating moving regions from these lists, which can then be imported into and processed by moving objects databases.

N2 - Complaints regarding knee joints resulting from musculoskeletal degenerative or injury-related conditions are common, increase with age, and are associated with rising demand for treatments by physicians and therapists. The success of a therapeutic intervention is frequently contingent upon necessary time- and resource-intensive examinations to identify and differentiate the patient’s specific issues. In connection with non-surgical knee joint treatment, a crosssectoral, multidisciplinary research team has developed a concept for training artificial neural networks to assist in medical and physiotherapeutic examinations. After all, there is great potential for artificial intelligence (AI) in healthcare, particularly in collecting and analyzing large amounts of data. The KINEESIO project is training and testing screening tools supported by artificial intelligence for the assessment of patients with knee joint disorders. These tools support the workflows between healthcare providers and patients, improve the differentiation of individual symptoms and serve the decisionmaking process towards appropriate care. This should conserve healthcare resources and enable sufficient high-quality treatment.

Recent scholars study design for automation to facilitate robotization in design and planning. Besides, it has the potential to enable circularity to assist in the current resource crisis. This article explores how robotization can foster the circular built environment with design for fabrication, assembly and disassembly in current practice. This article first presents the industry adoption of robotization through design for fabrication, assembly and disassembly (Design for X) and Robot-Oriented Design (ROD) in Japan and abroad. Secondly, based on the concept of ROD, this work investigates how this fosters the circular built environment through industry review and literature review. It is concluded with three takeaways of robotization for the circular built environment with ROD and future directions in research.

Despite the potential benefits, many companies struggle with the implementation of agile methodologies. Through a systematic literature review of recent publications, we identify and categorize 19 challenges into three main areas: people, leadership, and organisation/processes. Our findings highlight that the most significant issues arise within the 'people' category, including plan-driven thinking, lack of knowledge, and inefficient collaboration. Leadership challenges involve insufficient management support and cultural mismatches, while organisation/process-related issues encompass inadequate planning and coordination. By synthesizing these challenges, this study provides a comprehensive overview aimed at helping practitioners anticipate and mitigate potential obstacles, thereby increasing the likelihood of successful agile transformations. These insights extend existing knowledge and emphasize the need for a holistic approach to manage the people, the leadership, and the organisation/process challenges of agile transformation.

This initiative launches the i-WOBAL didactical guide, together with the establishment of the digital school of WBL facilitators, a digital learning space designed to translate the theoretical framework of the guide into practical, actionable strategies for facilitators. The project is the result of the coordinated work of a consortium of 7 higher education and vocational training institutions from 5 different European countries. The digital school of WBL facilitators serves as a training hub where facilitators from both academic institutions and the business sector receive specialised training to effectively guide and support students. The digital school offers a structured curriculum, including modules on relevant soft skills, to ensure that facilitators are well equipped to manage and enhance the WBL experience for students. This paper describes the curriculum and pedagogical approaches of the digital school of WBL facilitators, its role in facilitating the practical application of WBL strategies and the collaboration of the partners to bring in their unique expertise. The collaborative nature of the i-WOBAL project, involving a consortium of European educational and corporate institutions, promotes a shared culture of best practice and continuous innovation in WBL. The potential scalability of this model offers significant implications for future educational policies aimed at standardising and improving the facilitation of WBL across different educational systems and market environments.

Early diagnosis reduces mortality rates and prevents disfiguring effects in different body regions. In recent years, machine learning techniques, particularly deep learning, have shown promising results in this task, presenting studies that have demonstrated that combining a patient’s clinical information with images of the lesion is crucial for improving the classification of skin lesions. Despite that, meaningful use of clinical information with multiple images is mandatory, requiring further investigation. Thus, this project aims to contribute to developing multimodal machine learning-based models to cope with the skin lesion classification task employing a lightweight transformer model. As a main hypothesis, models can take multiple images from different sources as input, along with clinical information from the patient’s history, leading to a more reliable diagnosis. Our model deals with the not-trivial task of combining images and clinical information (from anamneses) concerning the skin lesions in a lightweight transformer architecture that does not demand high computation resources but still presents competitive classification results.

Auch bei therapeutischen Maßnahmen wie der endoskopischen Submukosadissektion (ESD) könne relevante anatomische Strukturen durch KI mit hoher Genauigkeit erkannt und im endoskopischen Bild in Echtzeit markiert werden. Der Effekt einer solchen Applikation auf die Gefäßdetektion von Endoskopikern ist bislang nicht erforscht. Ziele:  In dieser Studie wurde der Effekt eines KI-Algorithmus zur Echtzeit-Gefäßmarkierung bei ESD auf die Gefäßdetektionsrate von Endoskopikern untersucht. Methodik:  59 third space Endoskopievideos wurde aus der Datenbank des Universitätsklinikums Augsburg extrahiert. Auf 5470 Einzelbildern dieser Untersuchungen wurde submukosale Blutgefäße annotiert. Zusammen mit weiteren 179681 unmarkierten Bildern wurde ein DeepLabV3+ neuronales Netzwerk mit einer semi-supervised learning Methode darin trainiert, submukosale Blutgefäße auf dem endoskopischen Bild zu erkennen und in Echtzeit einzuzeichnen. Anhand eines Videotests mit 101 Videoclips und 200 vordefinierten Blutgefäßen wurden 19 Endoskopiker mit und ohne KI Unterstützung getestet. Ergebnis:  Der Algorithmus erkannte in dem Videotest 93.5% der Gefäße in einer Detektionszeit von im Median 0,3 Sekunden. Die Gefäßdetektionsrate von Endoskopikern erhöhte sich durch KI Unterstützung von 56,4% auf 72,4% (p<0.001). Die Gefäßdetektionszeit reduzierte sich durch KI-Unterstützung von 6,7 auf 5.2 Sekunden (p<0.001). Der Algorithmus zeigte eine Rate an falsch positiven Detektionen in 4.5% der Einzelbilder. Falsch positiv erkannte Strukturen wurde kürzer detektiert, als richtig positive (0.7 und 6.0 Sekunden, p<0.001). Schlussfolgerung:  KI Unterstützung führte zu einer erhöhten Gefäßdetektionsrate und schnelleren Gefäßdetektionszeit von Endoskopikern. Ein möglicher klinischer Effekt auf die intraprozedurale Komplikationsrate oder Operationszeit könnte in prospektiven Studien ermittelt werden.

Depending on the carbon content of the steel used, it either exclusively contains TiC or additional other phases. In the case of steel with a medium carbon concentration (0.67 wt.% C), a pure TiC layer forms. A preparation methodology was developed to make statements about functional and microstructural properties of the respective layers such as layer thickness, porosity, or grain size. However, apart from the diffusion layer’s microstructure, it also reveals the microstructure of the two base substrates. A comparison based on electron backscatter diffraction (EBSD) examinations yields similar results in terms of microstructure. A micrograph analysis based on the new preparation methodology also allows confirming the element distribution measurement by glow discharge optical emission spectroscopy (GDOES). The methodology therefore provides a way of quickly and reliably controlling the layer formation during the hot pressing process of titanium and carbon steel.

Um eine Aussage über die funktionalen und mikrostrukturellen Eigenschaften, wie Schichtdicke, Porosität oder Korngröße, entsprechender Schichten treffen zu können, wurde eine Präparationsmethodik entwickelt. Hierbei wird jedoch nicht nur das Gefüge der Diffusionsschicht, sondern auch das der beiden Grundsubstrate entwickelt. Ein Vergleich mit Elektronenrückstreubeugungs-Untersuchungen (EBSD) liefert hinsichtlich der Mikrostruktur vergleichbare Ergebnisse. Auch die Messung der Elementverteilung durch Glimmentladungsspektroskopie (GDOES) kann durch eine Schliffbildanalyse unter Anwendung der neuen Präparationsmethodik belegt werden. Die Methodik stellt also eine Möglichkeit zur schnellen und sicheren Kontrolle der Schichtbildung beim Heißpressen von Titan und Kohlenstoffstahl dar.

Die Rolle von KI bei therapeutischen Maßnahmen wurde noch nicht eingehend untersucht. Eine intraprozedurale Phasenerkennung bei endoskopischer Submukoasdissektion (ESD) könnte die Erhebung von Qualitätsindikatoren ermöglichen. Weiterhin könnte diese Technologie zu einem tieferen Verständnis über die Eigenschaften der Prozedur führen und weiterführende Applikationen zur automatischen Dokumentation oder standardisiertem Training vorbereiten. Ziele: Ziel dieser Studie war die Entwicklung eines KI Algorithmus zur intraprozeduralen Phasenerkennung bei endoskopischer Submukosadissektion. Methodik:  2071546 Einzelbilder aus 27 ESD Videos in voller Länge wurden für die übergeordneten Klassen Diagnostik, Markierung, Nadelinjektion, Dissektion und Blutung, sowie die untergeordneten Klassen Endoskop-Manipulation, Injektion und Applikation von elektrischem Strom annotiert. Mit einem Trainingsdatensatz (898440 Einzelbilder, 17 ESDs) wurde ein Video Swin Transformer mit uniformer Stichprobenentnahme trainiert und intern validiert (769523 Einzelbilder, 6 ESDs). Neben der internen Validierung wurde der Algorithmus anhand von einem separaten Testdatensatz (403583 Einzelbilder, 4 ESDs) evaluiert. Ergebnis:  Der F1 Score des Algorithmus für alle Klassen lag in der internen Validierung bei 83%, in dem separaten Test bei 90%. Anhand des separaten Tests wurden true positive (TP)-Raten für Diagnostik, Markierung, Nadelinjektion, Dissektion und Blutung von 100%, 100%, 96%, 97% und 93% ermittelt. Für Endoskopmanipulation, Injektion und Applikation von Elektrizität lagen die TP-Raten bei 92%, 98% und 91%. Schlussfolgerung:  Der entwickelte Algorithmus klassifizierte ESD Videos in voller Länge und anhand jedes einzelnen Bildes mit hoher Genauigkeit. Zukünftige Forschungsvorhaben könnten intraoperative Qualitätsindikatioren auf Basis dieser Informationen entwickeln und eine automatisierte Dokumentation ermöglichen.

A1 - Shamonin (Chamonine), Mikhail T1 - On the Piezomagnetism of Magnetoactive Elastomeric Cylinders in Uniform Magnetic Fields: Height Modulation in the Vicinity of an Operating Point by Time-Harmonic Fields JF - Polymers N2 - Soft magnetoactive elastomers (MAEs) are currently considered to be promising materials for actuators in soft robotics. Magnetically controlled actuators often operate in the vicinity of a bias point. Their dynamic properties can be characterized by the piezomagnetic strain coefficient, which is a ratio of the time-harmonic strain amplitude to the corresponding magnetic field strength. Herein, the dynamic strain response of a family of MAE cylinders to the time-harmonic (frequency of 0.1-2.5 Hz) magnetic fields of varying amplitude (12.5 kA/m-62.5 kA/m), superimposed on different bias magnetic fields (25-127 kA/m), is systematically investigated for the first time. Strain measurements are based on optical imaging with sub-pixel resolution. It is found that the dynamic strain response of MAEs is considerably different from that in conventional magnetostrictive polymer composites (MPCs), and it cannot be described by the effective piezomagnetic constant from the quasi-static measurements. The obtained maximum values of the piezomagnetic strain coefficient (∼102 nm/A) are one to two orders of magnitude higher than in conventional MPCs, but there is a significant phase lag (35-60°) in the magnetostrictive response with respect to an alternating magnetic field. The experimental dependencies of the characteristics of the alternating strain on the amplitude of the alternating field, bias field, oscillation frequency, and aspect ratio of cylinders are given for several representative examples. It is hypothesized that the main cause of observed peculiarities is the non-linear viscoelasticity of these composite materials.

Methodik:  22 Endoskopiker aus zwölf Zentren mit unterschiedlicher Barrett-Erfahrung untersuchten 96 standardisierte Endoskopievideos. Die Untersucher wurden in Experten und Nicht-Experten eingeteilt und nach dem Zufallsprinzip für die Bewertung der Videos mit oder ohne KI eingeteilt. Die Teilnehmer wurden in zwei Gruppen aufgeteilt: Arm A bewertete zunächst Videos ohne KI und dann mit KI, während Arm B die umgekehrte Reihenfolge einhielt. Die Untersucher hatten die Aufgabe, BÖ-assoziierte Neoplasien zu erkennen und ihr Konfidenzniveau sowohl mit als auch ohne KI auf einer Skala von 0 bis 9 anzugeben. Ergebnis:  In Arm A erhöhte der Einsatz von KI das Konfidenzniveau bei beiden signifikant (p<0.001). Bemerkenswert ist, dass jedoch nur Nicht-Experten durch die KI eine signifikante Verbesserung der Sensitivität und Spezifität (p<0.001 bzw. p<0.05) erfuhren. Während Experten ohne KI im Vergleich zu Nicht-Experten mit KI ein höheres Konfidenzniveau aufwiesen, gab es keinen signifikanten Unterschied in der Genauigkeit. In Arm B zeigten beide Gruppen eine signifikante Abnahme des Konfidenzniveaus (p<0.001) bei gleichbleibender Genauigkeit. Darüber hinaus wurden in 9% der Entscheidungen trotz korrekter KI eine falsche Wahl getroffen. Schlussfolgerung:  Der Einsatz künstlicher Intelligenz steigerte das Konfidenzniveau sowohl bei Experten als auch bei Nicht-Experten signifikant – ein Effekt, der im Studienmodell reversibel war. Darüber hinaus wiesen Experten mit oder ohne KI durchweg höhere Konfidenzniveaus auf als Nicht-Experten mit KI, trotz vergleichbarer Ergebnisse. Zudem konnte beobachtet werden, dass die Untersucher in 9% der Fälle die KI zuungunsten des Patienten ignorierten.

MAIN is a theory-based tool designed to evaluate the narrative abilities of children who are learning one or more languages from birth or early in their development. It provides a standardized way to measure how well children can comprehend and produce stories across different languages and referential norms for children between 3 and 12 years old. MAIN has been adapted to over ninety languages and is used in over 65 countries. The MAIN analysis focuses on story structure and story complexity which are typically evaluated manually based on scoring sheets. We here investigate the automation of this process using BERT-based classification which already yields promising results.

However, this integration also introduces significant challenges, particularly in governance. This paper presents a comprehensive literature review of IT/OT convergence, focusing on the governance challenges and strategies drawn from both academic and practitioner literature. The findings reveal that effective governance is crucial for successful IT/OT convergence, requiring clear definitions of roles and responsibilities, cross-functional collaboration, and a unified approach to mitigate risks and align organizational goals. Key IT/OT convergence governance strategies include establishing a Center of Excellence, adopting a risk-based approach, and fostering a culture of change. The paper highlights the need for further research to develop comprehensive governance frameworks and empirically examine the impact of governance on IT/OT convergence success. This paper provides valuable insights for both researchers and practitioners navigating the complexities of IT/OT convergence and governance in the era of Industry 4.0.

Due to data protection guidelines, development with clear data is often difficult. One way to overcome this difficulty is to desensitize documents using document redaction. The following study, therefore, examines the impact of redaction on the document classification performance of a deep CNN model by analyzing how the classifica- tion performance deteriorates when the model is trained on unredacted documents and evaluated on redacted data (unredacted model) or trained on redacted data and applied to unredacted documents (redacted model). For the former condition, a loss in accuracy of 2.56%P was found and a loss of 2.08%P for the latter. We were also able to show that the loss in performance differed greatly between document classes and was influenced by their proportion of redacted area (unredacted model: r=0.31; redacted model: r=0.87). For the model trained with redacted and evaluated on unredacted data, we also determined that the decrease in classification accu- racy was affected by the intra-class variability of the redacted area (r=0.74). From these results, recommendations for dealing with redacted data in document classification systems are derived.

However, integrating LLM into conventional applications poses challenges due to their non-deterministic nature. This paper introduces a framework designed to effectively integrate LLM into intermediate modules by ensuring more consistent and reliable outputs. The framework includes three key components: the Sieve, which captures and retries processing of incorrect outputs; the Circuit Breaker, which stops processing persistently incorrect outputs; and the Optimizer, which enhances processing efficiency by combining inputs into single prompts. Experimental results employing structured methodology demonstrate the framework's effectiveness, achieving significant improvements a 71.05% reduction in processing time and an 82.97% reduction in token usage while maintaining high accuracy. The proposed framework, agnostic to specific LLM implementations, aids the integration of LLMs into diverse applications, enhancing automation and efficiency in fields such as finance, healthcare, and education.

T1 - Validated Multiphysics Modeling For Advanced Pipeline Integrity Management T2 - ADIPEC, November 4–7, 2024, Abu Dhabi, UAE N2 - The aim of this paper is to present practical steps for utilizing a validated multiphysics approach for fracture control in CO2 pipelines within the framework of Carbon Capture Transport and Storage (CCTS). Ensuring the arrest of running ductile fracture (RDF) is a crucial safety requirement for the transportation of dense-phase CO2. However, current standards rely on outdated and restrictive methods, imposing severe limitations on pipeline material and structural design. As a result, projects that fall outside these standards face the need for extremely costly tests, often leading to delays or cancellations of CCTS initiatives. This study introduces an advanced, validated, fully-coupled fluid-structure interaction (FSI) model designed to accurately predict fracture propagation in CO2 pipelines. A key advantage of this approach is its use of robust and reproducible calibration and validation procedures combined with high-quality material characterization data. The full coupling of structural, fluid, and backfill models is essential for obtaining precise results, not only in determining arrest occurrence but also in analyzing properties such as fracture velocity history, 3D pressure distributions behind the propagating crack, wall thinning, and crack tip opening angle. The FSI model has demonstrated its value as a cost-effective tool for safety assessments, enabling the development of fracture control plans that specify minimum required material properties and fluid compositions for optimized pipeline design, both onshore and offshore. Additionally, performing virtual studies with the parameterized FSI model enables the generation of synthetic data for training and validating a machine learning surrogate model. This surrogate model can be integrated into industrial practices, facilitating the application of multiphysics modeling without the need for extensive expertise.

Although its tendency to localized corrosion is a limiting factor in its use. Electropolishing is a widely used process for improving the surface roughness and corrosion behavior of metals. However, there is a lack of knowledge about the electropolishing of magnesium and its alloys. In this study, an optimal electropolishing process for AZ31 was developed to improve the surface properties by varying the electrolyte concentration and the applied potential. The electrolyte composition was a mixture of phosphoric acid, ethanol and deionized water. The applied potentials were selected based on measured current density potential curves. Thereby, electropolishing was performed up to an electric charge of 18 As. The experimental results indicate that the electropolishing process should be carried out at a low current density to avoid bubble evolution and surface defects. Therefore, the concentration of the electropolishing electrolyte should have an appropriate low conductivity, and the applied potential should be in the transient or passive region of the polarization curve recorded prior to electropolishing. It could be shown that an optimized electropolishing process improved the surface of AZ31 by providing a bright and mirror-like surface and a lower roughness compared to a mechanically ground surface.
