Incorporating hexagonal boron nitride (hBN) as a dry lubricant into the feedstock powder can further enhance wear resistance and thermal conductivity, crucial for preventing premature failure caused by inadequate lubrication. In this study, the mass fraction of hBN was varied between 0 and 15 wt.\% to assess its influence on the tribological performance of the coatings using pin-on-disk tests. The coating's hardness was measured via the Vickers method, and its cracking tendency at the coating/substrate interface was evaluated. Scanning electron microscopy (SEM) and X-ray diffraction (XRD) were employed to analyze the microstructure and phase composition, while thermal diffusivity was determined using the laser flash method. The findings revealed that the inclusion of hBN, at concentrations of up to 10 wt.\%, leads to an improvement in thermal diffusivity and a reduction in the coefficient of friction. However, exceeding this threshold leads to a decrease in hardness and increased crack formation tendency, highlighting the trade-off between frictional and mechanical properties.}, language = {en} } @article{LabandEskenPollerbergetal.2024, author = {Laband, Dana Laureen and Esken, Henning and Pollerberg, Clemens and Joemann, Michael and Doetsch, Christian}, title = {Analysis of the Potential for Thermal Flexibility of Cooling Applications}, series = {Energies}, volume = {2024}, journal = {Energies}, number = {17(8), Artikel Nr. 4685}, publisher = {MDPI}, doi = {10.3390/en17184685}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1010-opus4-47285}, pages = {19}, year = {2024}, abstract = {The feed-in of electricity from renewable energies, such as wind or solar power, fluctuates based on weather conditions.

Various cooling-demand profiles are investigated with respect to their load profile and their impact on flexibility is analysed. In addition to the cooling demand, scenarios of different storage dimensions are considered. As a result, it shows that an increasing base-load level and increasing operating-load duration have a negative effect on flexibility, while an increasing full-load duration is beneficial for flexibility.

The study aimed at understanding how CSR, coupled with employees' moral attitudes, admiration for their organization, and climate change awareness influences sustainable practices by realizing the complex interplay between company initiatives and personal psychology. The participants were staff members who worked in several hotels in China where there were active CSR programs. Using established scales, we collected 422 valid responses over three waves to strengthen our data collection process. Empirically, it was found that CSR directly influenced food-waste-reduction behavior. Additionally, it was discovered that this relationship was mediated by moral attitudes and employee admiration as well as moderated by awareness of climate change. The findings have substantial theoretical implications regarding the interaction between emotional and cognitive factors within the CSR framework to influence behavior among employees. This paves the way for creating well-rounded strategies that appeal to staff and encourage sustainability in the hotel business. While focused on China's hospitality industry, this research creates room for future studies in other places around the world using various methods.

We define three privacy scenarios to understand when and how users benefit from these regional lists and what effect they have in practice. The results show that although the lists differ significantly, the number of rules they contain is unrelated to the number of blocked requests. We find that the lists' overall efficacy varies notably. Filter lists also do not meet the expectation that they increase user protection in the regions for which they were designed.

Dissimilar welded joints demonstrate inferior material strength. This fact can be attributed to the inherent coarse microstructure of the cast material.

In contrast to cumbersome paper-based surgical instrument manuals still used in the OR, we wish to provide surgical staff with an AR head-mounted display that provides in-situ visualization and guidance throughout the assembly process of surgical instruments. Our requirement analysis supports the development and provides guidelines for its transfer into surgical practice. Methods A three-phase user-centered design approach was applied with online interviews, an observational study, and a workshop with two focus groups with scrub nurses, circulating nurses, surgeons, manufacturers, clinic IT staff, and members of the sterilization department. The requirement analysis was based on key criteria for usability. The data were analyzed via structured content analysis. Results We identified twelve main problems with the current use of paper manuals. Major issues included sterile users' inability to directly handle non-sterile manuals, missing details, and excessive text information, potentially delaying procedure performance. Major requirements for AR-driven guidance fall into the categories of design, practicability, control, and integration into the current workflow. Additionally, further recommendations for technical development could be obtained. Conclusion In conclusion, our insights have outlined a comprehensive spectrum of requirements that are essential for the successful implementation of an AI- and AR-driven guidance for assembling surgical instruments. The consistently appreciative evaluation by stakeholders underscores the profound potential of AR and AI technology as valuable assistance and guidance.}, language = {en} } @article{RajanKrochmalWegeneretal.2023, author = {Rajan, Aravindh Nammalvar Raja and Krochmal, Marcel and Wegener, Thomas and Hartmaier, Alexander and Niendorf, Thomas and Moeini, Ghazal}, title = {Micro-macro modeling of tensile behavior of a friction stir welded hybrid joint of AlSi10Mg parts produced by powder bed fusion and casting}, series = {Welding in the World}, volume = {68}, journal = {Welding in the World}, doi = {10.1007/s40194-024-01775-9}, pages = {1693 -- 1705}, year = {2023}, abstract = {Additive manufacturing (AM) has gained considerable interest due to its ability to produce lightweight parts with hierarchical microstructures. However, the current constraints on the build chamber size in powder-bed fusion type AM processes limit its industrial application. A hybrid welded joint, consisting of an AM-processed and a conventionally manufactured part, can be employed to produce larger components. Due to the varying processing conditions, these hybrid welded joints contain a wide range of microstructural heterogeneities, which influences the mechanical properties of the joint. Using a numerical model to predict the mechanical behavior of welded joints by considering the microstructural variations is essential for the safe and reliable implementation of hybrid welded joints. This study aims to predict the local tensile behavior of each region of a hybrid friction-stir welded joint of AlSi10Mg produced by laser-based powder bed fusion and casting using a microstructure-sensitive model as well as the global tensile behavior by considering the properties of each region using a joint macroscopic model. The results from this modeling approach agree well with the experimental results. Therefore, this method can predict the mechanical behavior of hybrid welded joints and can establish the structure-property relationship in each weld region.}, language = {en} } @techreport{UrbanGrosseKampmann2024, type = {Working Paper}, author = {Urban, Tobias and Große-Kampmann, Matteo}, title = {Integrating 6G and Tactile Internet in Participatory Healthcare: A Pathway to Enhanced Security and Resilience}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1010-opus4-45364}, year = {2024}, abstract = {This paper discusses the transformative potential of 6G technology and the tactile Internet in reshaping participatory healthcare models while architecturing these digital healthcare systems with security and resiliency by design.

In the current study, we investigate the role of hardiness and mindfulness as personal resources which help employees to effectively cope with such stressors and thereby prevent burnout. We focus on trait mindfulness as the innate capacity of paying and maintaining attention to present-moment experiences with an open and nonjudgmental attitude. It has been shown to promote concentration and well-being and to facilitate decision making; it is often seen as an important resource for overcoming challenges in everyday work life. Hardiness also constitutes a personality profile of dispositional resilience that describes how people deal with stressful events and includes the core aspects of challenge (conviction that challenges offer opportunities), engagement (actively tackling tasks and challenges) and a sense of control (conviction of influence over one's own life circumstances). People with high hardiness show better health and higher job satisfaction and performance. We build our hypothesis according to the extended version of the Job Demands-Resources model, which states that personal resources protect employees from burnout, because they shape employees' perceptions of and reactions towards their work environment. In a similar vein, stress theory suggests that personal resources mitigate burnout through lower stress appraisals, greater use of adaptive coping, and flexibility in matching coping to appraisals. We measured social stressors at work with the scale developed by Frese et al and further asked participants to work on the Maslach Burnout Inventory, the Mindful Attention and Awareness Scale and the short version of the Revised Norwegian Dispositional Resilience (Hardiness) Scale. Our cross-sectional study was based on a sample of N = 174 employees from a broad range of organizations and job types. Statistical Analyses revealed significant negative correlations of both personal resources with reported symptoms of burnout and the perception of social stressors as well. However, in line with prior research, they indeed did not attenuate the relationship between social stressors and emotional exhaustion at work.

Accurate translation of chemical compounds from SMILES notation into their corresponding IUPAC names is crucial, as it can significantly streamline the laborious process of naming chemical structures. Here, we present STOUT (SMILES-TO-IUPAC-name translator) V2, which addresses this challenge by introducing a transformer-based model that translates string representations of chemical structures into IUPAC names. Trained on a dataset of nearly 1 billion SMILES strings and their corresponding IUPAC names, STOUT V2 demonstrates exceptional accuracy in generating IUPAC names, even for complex chemical structures. The model's ability to capture intricate patterns and relationships within chemical structures enables it to generate precise and standardised IUPAC names.

In this work the mismatch of yield simulation results based on proprietary data, meaning interpolated or also called synthetical data, and data coming from a weather station in proximity to the installation is evaluated. The simulated data sets are compared to measurement data as obtained by the inverter output and hence give a profound understanding how interpolated data may influence the simulation results. The outcome shows that the quality of the yield simulation, if compared to the measurement data, is increased by a factor of up to four if on-site weather data is used as input for the simulation. The largest source of deviation is irradiation, which varies up to 10\% if synthetical and measured irradiation on-site is compared.

With the rise of digitalization not only in psychology but healthcare in general, digital drawing tools (dDTs) have also been developed for this purpose. This scoping review aims at summarizing the state of the art of dDTs available to assess mental health conditions in people above preschool age. Methods: PubMed, PsycInfo, PsycArticles, CINAHL, and Psychology and Behavioral Sciences Collection were searched for dDTs from 2000 onwards. The focus was on dDTs, which not only evaluate the final drawing, but also process data. Results: After applying the search and selection strategy, a total of 37 articles, comprising unique dDTs, remained for data extraction. Around 75 \% of these articles were published after 2014 and most of them target adults (86.5 \%). In addition, dDTs were mainly used in two areas: tremor detection and assessment of cognitive states, utilizing, for example, the Spiral Drawing Test and the Clock Drawing Test. Conclusion: Early detection of mental diseases is an increasingly important field in healthcare. Through the integration of digital and art based solutions, this area could expand into an interdisciplinary science. This review shows that the first steps in this direction have already been taken and that the possibilities for further research, e.g., on the optimized application of dDTs, are still open.}, language = {en} } @inproceedings{Meyer2024, author = {Meyer, Manfred}, title = {Worth Every Penny: The Invaluable Returns of Investing in Intercultural and Interdisciplinary Project-Based Learning in Higher Education}, series = {ICERI 2024: Proceedings of 17th Annual International Conference of Education, Research and Innovation.

While generating many advantages, these developments have disadvantages and risks. Therefore, this study addresses the critical security and privacy concerns related to the digital transformation of healthcare. Our work focuses on the challenges of managing and understanding cognitive data within the CPI and the potential threats from analyzing such data. It proposed a comprehensive analysis of potential vulnerabilities and cyber threats, emphasizing the need for robust security frameworks designed with resilience in mind to protect sensitive cognitive data. We present scenarios for reward and punishment systems and their impacts on users. In conclusion, we outline a vision for the future of secure, resilient, and patient-centric digital healthcare systems that leverage 6G and the tactile Internet to enhance the CPI. We offer policy recommendations and strategic directions for stakeholders to create a secure, empowering environment for patients to manage their cognitive health information.}, language = {en} } @article{Wienbracke2024, author = {Wienbracke, Mike}, title = {Werbung mit Preisreduzierung muss auf Basis des niedrigsten Preises der letzten 30 Tage berechnet werden}, series = {Gesellschafts- und Wirtschaftsrecht (GWR)}, volume = {16}, journal = {Gesellschafts- und Wirtschaftsrecht (GWR)}, number = {24}, pages = {405 -- 405}, year = {2024}, language = {de} } @article{Wienbracke2024, author = {Wienbracke, Mike}, title = {„Am siebten Tage sollst Du ruhen" - und nicht shoppen!}, series = {Verwaltungsrundschau (VR)}, volume = {70}, journal = {Verwaltungsrundschau (VR)}, number = {12}, pages = {415 -- 421}, year = {2024}, language = {de} } @inproceedings{ThiemExternbrink2024, author = {Thiem, Verena Katharina and Externbrink, Kai}, title = {Authentische F{\"u}hrung und ihre gesundheitsbezogenen Konsequenzen f{\"u}r Mitarbeitende - eine Betrachtung psychischer und k{\"o}rperlicher Symptome}, series = {Gesundheit - gemeinsam : Kooperationstagung (GMDS, DGSMP, DGEpi, DGMS, DGPH) ; 08.09. - 13.09.2024, Dresden}, booktitle = {Gesundheit - gemeinsam : Kooperationstagung (GMDS, DGSMP, DGEpi, DGMS, DGPH) ; 08.09. - 13.09.2024, Dresden}, year = {2024}, language = {de} } @incollection{Wienbracke2024, author = {Wienbracke, Mike}, title = {\S 12a KAG NRW}, series = {Kommunalabgabengesetz f{\"u}r das Land Nordrhein-Westfalen (KAG NRW) [Loseblattwerk]}, booktitle = {Kommunalabgabengesetz f{\"u}r das Land Nordrhein-Westfalen (KAG NRW) [Loseblattwerk]}, publisher = {KSV Medien}, address = {Wiesbaden}, publisher = {Westf{\"a}lische Hochschule Gelsenkirchen Bocholt Recklinghausen}, year = {2024}, language = {de} } @techreport{Loeffler2024, author = {L{\"o}ffler, Markus Jan}, title = {Steckbriefe zur Energiewende}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1010-opus4-46088}, pages = {48}, year = {2024}, abstract = {In dem Bericht werden insbesondere auf Daten der Bundesnetzagentur (2022) basierende Steckbriefe s{\"a}mtlicher bei der simulatorischen Behandlung der generellen Leistungsverh{\"a}lt-nisse in einem der geplanten Energiewende unterworfenen Energieversorgungssystem darge stellt. Die Steckbriefe umfassen die auftretenden Leistungsverl{\"a}ufe der Versorgung aus Photovoltaik, Windkraft, Biomasse usw. und des Verbrauchs mit Stromdirektverbrauchern, W{\"a}rmepumpen und Elektro-Fahrzeugen. F{\"u}r den Verbrauch werden zwei Lastvarianten angegeben. Elektrolyseure sind in beiden Varianten nicht ber{\"u}cksichtigt, da sie trotz ihrer hohen Verluste dem Bereich der Wasserstoffspeicherung zugeordnet werden. Ebenso werden Wasserstoff-Kraftwerke weder dem Bereich der Erzeuger oder, aufgrund ihrer hohen Verluste, der Verbraucher zugeordnet; diese sind ebenfalls dem Bereich der Wasserstoffspeicherung zuzuordnen. Die Leistungsverl{\"a}ufe werden erg{\"a}nzt durch „Heatmaps", mit deren Hilfe sich die Leistungsverl{\"a}ufe in vorteilhafter Weise tages- und stundenweise aufl{\"o}sen lassen. Im Gegensatz zur normalen Darstellung der Leistungsverl{\"a}ufe, aus denen sich saisonale Leistungsg{\"a}nge und Leistungswerte sehr gut ablesen lassen, lassen sich aus diesen Heatmaps auch Tagesg{\"a}nge aufgrund menschlicher Verhaltensweisen ermitteln. Statistiken zur Verteilung der Leistungswerte und Tabellen mit den wichtigsten Eckwerten der entsprechenden EE-Erzeuger und Verbraucher vervollst{\"a}ndigen die Steckbriefe. In Einzelf{\"a}llen werden noch Zusatzerl{\"a}uterungen gegeben, ohne die sich die entsprechenden Steckbriefe unvollst{\"a}ndig w{\"a}ren. Insgesamt ergibt sich, dass der Stromverbrauch ab 2045 saisonal enorm ausgepr{\"a}gte Maxima und Minima aufweist, die erheblich von den Maxima und Minima des heutigen Stromverbrauchs abweichen. Dies ist das Resultat des Stromverbrauchs aus W{\"a}rmepumpen und Elektro-Fahr-zeugen. Die Verbrauchsmaxima k{\"o}nnen dabei Werte von etwa 170 GW erreichen, was im Gegensatz zu heutigen Maxima von weniger als 90 GW als bemerkenswert bezeichnet werden muss. In jedem Fall wird ein steuerbarer Backup-Kraftwerkspark ben{\"o}tigt, dessen kontinuierliche Verf{\"u}gbarkeit w{\"a}hrend eines Tages gr{\"o}ßer wie 2 Stunden sein muss. Er muss gezielt zur Morgenzeit, typischerweise zwischen 05:00 und 07:00, mit Leistungsh{\"u}ben von 20 GW/h eingeschaltet und abends, typischerweise zwischen 18:00 und 20:00, mit Lastabw{\"u}rfen von {\"u}ber 22 GW/h gezielt wieder abgeschaltet werden k{\"o}nnen.

Das Strommarktdesign solle einen Paradigmenwechsel im Strommarkt herbeif{\"u}hren. Eingef{\"u}hrt werden soll ein Kapazit{\"a}tsmarkt, eine Art systemische Grundgeb{\"u}hr, zur Finanzierung unwirtschaftlicher Investitionen in k{\"u}nftig nur wenig auslastbare Kraftwerke. Zudem sollen die Stromverbraucher als Regelkomponente in einer zuk{\"u}nftig volatilen Stromversorgung eingesetzt werden. Die Motivation hierzu soll mit Hilfe dynamischer Stromtarife gelingen. Vorliegende Studie befasst sich insbesondere mit der potentiellen Wirkung dynamischer Strom-preise auf den Stromverbrauch. Hierzu wird das Einsparpotenzial bei Nutzung dieser Stromtarife untersucht. Empirische Befunde aus Deutschland und Schweden unterf{\"u}ttern und erweitern diese Untersuchung mit Blick auf die erhoffte Beeinflussbarkeit des k{\"u}nftigen, den politischen Energiewende-Planungen unterworfenen Stromversorgungssystems. Die Untersuchungsergebnisse werden wie folgt interpretiert: • In „Smart-Grids" k{\"o}nnen dynamische Stromtarife das Verbraucherverhalten bei einem Einsparpotential von 10 bis 15\% begrenzt beeinflussen. • Der Einfluss beschr{\"a}nkt sich auf lokale Stromversorgungsnetze. • Der Stromverbrauch wird in dem Sinne vergleichm{\"a}ßigt, dass tageweise auftretende Lastspitzen und Lastt{\"a}ler sich durch Lastverschiebungen ausgeglichener darstellen. Die Differenz der beiden Tagesextremwerte k{\"o}nnte um bis zu 20\% sinken. • Der j{\"a}hrliche Stromverbrauch wird hierdurch nicht wahrnehmbar beeinflusst. Der qualitative Verlauf des Lastgangs ebenso wenig. • Die Vergleichm{\"a}ßigung ist in dem Sinne netzdienlich, dass nur unzureichend ausgebaute Ortsnetze durch die k{\"u}nftige zunehmende Beanspruchung durch Elektromobilit{\"a}t und W{\"a}rmepumpen nicht {\"u}berbeansprucht werden bzw. dass deren sowieso notwendiger Ausbau in etwas reduzierter Weise ausgef{\"u}hrt werden kann. • Die grundlegenden Probleme bzw. Herausforderungen des geplant volatilen Gesamtstromversorgungssystems lassen sich durch Einsatz der Stromverbraucher als system-dienliches Regelglied nicht l{\"o}sen. Dazu ist ihre Wirkung im Vergleich zur {\"u}ber das Jahr gemittelten Last zu gering. Der gew{\"u}nschte Ausgleich sollte besser mit Hilfe geeigneter Speicher statt mit humanen Ressourcen als Regelglied gel{\"o}st werden. Prinzipiell kann die geplante Flexibilisierung des Strommarktes als eine gut vermittelbare und von den Stromkunden nur schlecht zu erkennende Form der Energierationierung durch Preismechanismen gesehen werden. Energierationierungen signalisieren oft strukturelle Probleme im Energiesektor eines Landes. Die Frage, ob der vom BMWK vorgeschlagene Paradigmenwechsel bereits in diese Richtung zielt, darf zusammen mit den derzeit immer offener und h{\"a}ufiger zutage tretenden, bisher noch verkraftbaren Dysfunktionalit{\"a}ten der derzeitigen Stromversorgung durchaus in Betracht gezogen werden.}, language = {de} } @techreport{Schmitz2022, author = {Schmitz, Alexander}, title = {Ereignisbasierte System{\"u}berwachung von Windows-PCs}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1010-opus4-41984}, pages = {IV, 249}, year = {2022}, abstract = {Diese Arbeit bietet einen {\"U}berblick {\"u}ber das Thema der ereignisbasierten System{\"u}berwachung von Windows-PCs.
