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.

This unpredictability due to volatile feed-in can lead to sudden changes in energy generation so that solutions ensuring grid stability need to be implemented. The cooling sector offers the opportunity to create flexibilities for such balancing, with this study focusing on the thermal flexibilities that can be provided by cooling applications. 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. Storage size also has a strong impact as higher storage capacity and storage performance indicate higher flexibility, whereas above a certain size they only provide little added value.

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. The conclusions drawn underline the critical role of CSR in promoting environmental sustainability in the hospitality industry, providing a pathway for organizations to engage employees in meaningful and impactful sustainability initiatives.

T1 - Development of a Seed Treatment with Pochonia chlamydosporia for Biocontrol Application JF - Agriculture N2 - Seed treatment is a powerful technique for adding beneficial ingredients to plants during the seed preparation process. Biopolymers as drying agents and delivery systems in seed treatments were investigated for their biocompatibility with blastospores of the nematophagous fungus Pochonia chlamydosporia. To produce a novel seed treatment for the cover crop Phacelia tanacetifolia, xanthan gum TG and gellan gum were the most promising biopolymers in combination with potato starch and bentonite. The seed treatment process as well as the drying process were specially designed to be scalable, which make it suitable for applying the developed seed treatment in agriculture. Application of gellan gum in seed treatments led to 6.3% ± 1.6% of vital blastospores per seed compared to 3.8% ± 0.3% of vital blastospores when applying xanthan gum. Storage tests for seed treatments with 0.5% gellan gum indicated a higher stability at 4 °C compared to storage at 21 °C. After 42 days of storage at 4 °C, 54.1% ± 15.1% of the applied blastospores were viable compared to 0.3% ± 0.8% at 21 °C. This novel seed treatment application with P. chlamydosporia blastospores includes the seed treatment procedure, drying process, and storage tests and can easily be upscaled for application in agriculture.

Asynchronously accessing the VM ’s memory can be insufficient for efficiently monitoring what is happening inside of a VM. Active VMI introduces breakpoints to intercept VM execution at relevant points. Especially for frequently visited breakpoints, and even more so for production systems, it is crucial to keep their performance overhead as low as possible. In this paper, we provide a systematization of existing VMI breakpoint implementation variants, propose workloads to quantify the different performance penalties of breakpoints, and implement them in the benchmarking application bpbench. We used this benchmark to measure that, on an Intel Core i5 7300U, SmartVMI’s breakpoints take around 81 μs to handle, and keeping the breakpoint invisible costs an additional 21 μs per read access. The availability of bpbench facilitates the comparison of disparate breakpoint mechanisms and their performance optimization with immediate feedback.

In einem nahezu unentwirrbaren Kommunikationsdschungel aus Medien, Internetportalen und sozialen Plattformen wird es nicht nur für Laien immer schwieriger, verlässliche und unseriöse Kommunikation voneinander zu unterscheiden. So steigt die Anzahl derer, die professioneller Kommunikation mit Misstrauen begegnen und in ihr vor allem Einflussnahme oder gar Manipulation sehen. Aus den Augen gerät dabei oft, dass Deutschland über eines der freiheitlichsten und vielfältigsten Mediensysteme der Welt verfügt. Das Buch diskutiert die Grenzen zwischen Manipulation und Kommunikation on- wie offline und zeigt, wie man schlampige und seriöse Meinungsmacher unterscheidet, welche Rolle Fakten spielen und wie Medien und Unternehmen dazu beitragen können, dass Glaubwürdigkeit in der medialen Debatte wieder einen Stellenwert bekommt.

A1 - Domanski, Dmitri A1 - Frohne, Julia T1 - Evolutionary processes of cluster policies in post-industrial regions: implementing the smart specialisation strategy in the Ruhr Metropolis T2 - Beyond Innovation Hotspots N2 - Focusing on the implementation of the Smart Specialisation Strategy (S3), the chapter examines the development of cluster policies in the Ruhr Metropolis as a post-industrial region. The chapter traces the historical development of the Ruhr Area from its industrial peak in the 20th century to its slow transformation into a post-industrial landscape characterised by high urban density, new knowledge-based clusters and a persistent structural lack of effective regional cooperation. The analysis shows the conceptual shift from traditional cluster policies to the S3 approach, introduced by the European Union in 2014. The Smart Specialisation Strategy calls for a focus on comparative regional strengths and the involvement of a wide range of stakeholders in the identification of clusters for sustainable economic growth. The chapter also discusses the challenges and milestones in developing a coherent and effective Smart Specialisation Strategy, emphasising the need for inter-municipal cooperation and a new multi-level approach to regional governance. Using the case of the Ruhr Metropolis, the chapter highlights the opportunities and constraints of S3 policies to revitalise post-industrial regions by promoting innovation and adapting to global economic trends in cluster development, thus showing a way forward for other regions with similar structural challenges.

These lists are created and maintained by dedicated communities. Aside from popular blocking lists (e.g., EasyList), the communities create region-specific blocklists that account for trackers and ads that are only common in these regions. The lists aim to keep the size of a general blocklist minimal while protecting users against region-specific trackers. In this paper, we perform a large-scale Web measurement study to understand how different region-specific filter lists (e.g., a blocklist specifically designed for French users) protect users when visiting websites. 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. Finally, we show that the majority of the rules on the lists were not used in our experiment and that only a fraction of the rules would provide comparable protection for users.

Moreover, it provides insights into how corporate governance quality moderates the effects of personality. The analysis relied on the chief executive officers’ (CEOs’) speeches at annual general meetings (AGMs) that were voluntarily disseminated, a novel data source. Managers’ personality traits were measured using software-aided content analysis, and their impact on the debt ratio was analysed using panel regressions. Consistent with previous studies, the debt ratios of German issuers are significantly and positively related to the proxies of managerial certainty and narcissism. However, their model inclusion contributes only marginally to explanatory power. Conversely, the coefficients of the proxies for the Big Five personality traits remained statistically non-significant. Moreover, a significantly negative relationship between debt ratios and the interaction term between a proxy for corporate governance quality and managerial certainty is observed that corresponds to the risk-mitigating impact of corporate governance.

To validate the efficacy of said intervention training, a previous experiment was systematically replicated with a sample of N = 52 second-year police cadets. Participants were randomly assigned to the intervention training that focused on situational awareness, tactical gaze control, and visual attention, or an active control training that addressed traditional marksmanship skills. In a pre- and post-test, they had to engage in dynamic shoot/don't shoot video scenarios in an indoor firing range. Overall, the previous findings were replicated: Baseline levels of performance were elevated, yet the intervention group significantly improved their response time and time until the first hit. False positive decision-making cannot be reported at all; false negatives were marginal in the pre-test and eliminated after training. Further, the outcomes of the previous sample of senior officers and the present sample of cadets are compared and lead to the conclusion that the presented approach is a valuable extension of current training standards for both senior police officers and police cadets.

This study explored the representation types in kinesthetic action-imagery-practice (K-AIP) and visual action-imagery-practice (V-AIP) in a serial reaction time task using the crossed hand transfer paradigm. 169 participants (age M ± SD = 25.2 ± 3.9) were randomly assigned to AEP, K-AIP, V-AIP, or control-practice (CP), practicing with uncrossed hands on ten consecutive days. Tests involved the same sequence, a mirror sequence, a shifted sequence, and a shifted mirror sequence, each with uncrossed and crossed hands. With crossed hands, sequence-specific transfer effects indicated only little evidence for effector-independent representations in late stages of learning in AEP and V-AIP. Performance in the same sequence with uncrossed hands indicated the acquisition of stimulus-response location associated effector-dependent sequence-specific representations in AEP, K-AIP and V-AIP, but not in CP. These visual-spatial effector-dependent representations were stronger after AEP than after AIP. Overall, no important differences between both AIP groups were observed, and both groups reported similar focus on kinesthesis and vision, suggesting that irrespective of the instructions, rather than focusing on one single modality, AIP always involves a combination of both modalities - vision and kinesthesis - that promote motor learning.

We present three recently selected missions of the Robotics Task Force of the German Rescue Robotics Center (DRZ), where both ground and aerial robots were used to explore destroyed buildings. We describe and reflect the missions as well as the lessons learned that have resulted from them. To make robots from research laboratories fit for real operations, realistic outdoor and indoor test environments were set up at the DRZ and used for tests in regular exercises by researchers and emergency forces. On the basis of this experience, the robots and their control software were significantly improved. Furthermore, expert teams of researchers and first responders were formed, each with realistic assessments of the operational and practical suitability of robotic systems.

However, drawbacks such as pro- ductivity and dimension limitations adversely affect the employment of com- ponents processed by additive manufacturing (AM) in envisaged applications. This brings welding and joining techniques into play to integrate AM metal parts into larger assemblies. In the present study, electron beam welding is used to join the AlSi10Mg specimens, fabricated via two different manufacturing processes, that is, PBF-LB/M and casting. The main focus is to study the quasistatic and fatigue behavior of similar and dissimilar welded joints in different combinations, namely AM–AM, AM–cast, and cast–cast, alongside thorough microstructure analysis, to investigate the correlation between the microscopic and macroscopic properties. Dissimilar welded joints demonstrate inferior material strength. This fact can be attributed to the inherent coarse microstructure of the cast material. Although similar welded joints of AM components suffer from high porosity in the weld zone, they are characterized by a better fatigue life, which can be attributed to the equiaxed eutectic microstructure in the welded area.

While economic geography and regional development research extensively cover sustainable innovation and green regional development, innovation diffusion, demand-side aspects, and market emergence are often neglected. This paper illustrates how an enhanced valuation perspective that integrates materiality more directly helps to assess dynamic social processes of valuation in the case of low-carbon, resource efficient solutions. Through a path tracing approach, the paper assesses how two industrial by-products, slag sand and fly ash, evolved into highly valued secondary resources in Germany's Ruhr. Regional availability, market devices, and institutional work influence different dimensions of market valuation in waste-to-value processes. Insights on different phases of the development provide hint on how to organise and foster regional circular solutions. Findings may inform research and policy to advance emerging green industries, market creation for sustainable resources, and industrial decarbonisation, where the materiality of technologies and resources plays a key role.

The cap-and-trade approach will result in substantial price increases for fossil fuels which will affect affordability of the transport systems. Within this paper the regressive effect on car-owning households is described in different area categories of the urban and rural region in Germany. Equal-per-household redistribution of the carbon revenue could reverse the regressive effect into a progressive effect. However, there is substantial variation within the different economic status groups leaving notable shares of households with a very low economic status without a positive net transfer. This share will be lowest in the metropolises of the urban region and highest in small-sized cities/village areas of the urban and rural region. Particularly in the latter area categories, these households may need temporary mobility allowances due to limited abatement options. Despite the environmental bonus, electric car-owning households still belong to groups of higher economic status, and public transport supply is limited, particularly in the small-sized cities/village areas of the urban and rural region.

We focus on the 3-axis machining with realistic formed milling tools. The basis of the method lies in the identification of surface areas that cannot be reached by a given milling tool during optimization. For this purpose, we present an interpolation method that identifies these areas by an interpolation of the level set function along the outer contours of realistic milling tools, considering available machining directions. To minimize inaccessible surfaces, we define a potential field whose values decrease linearly into the outer normal direction of the structure. The inaccessible boundaries are pushed outward by minimizing their respective potential and therefore become accessible. Manufacturability is integrated into the optimization problem as an explicit constraint.

T1 - Requirement analysis for an AI-based AR assistance system for surgical tools in the operating room: stakeholder requirements and technical perspectives JF - International Journal of Computer Assisted Radiology and Surgery N2 - Abstract Purpose We aim to investigate the integration of augmented reality (AR) within the context of increasingly complex surgical procedures and instrument handling toward the transition to smart operating rooms (OR). 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.

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.

The study uses the example of Bernhard Benning, who headed the Economics Department of the Reichs-Kredit-Gesellschaft, one of the major banks owned by the German Reich during the National Socialist era. After the war Benning was appointed a member of the board of directors of the Deutsche Bundesbank for twenty-two years. As a student of Adolf Weber and his Munich school of economics, Benning's views were shaped by classical liberal rather than ordoliberal ideas. His legitimacy in postwar Germany stemmed from his public opposition to war financing and warnings about inflation during the Donner-Benning Debate of 1942–43. In this tradition, the early Bundesbank was Weberian rather than ordoliberal, so, for instance, fixed exchange rates were favored, and a strong business and investment perspective was adopted.

Community Health Konferenz, 21. + 22. November 2024, Bochum N2 - Experiencing relational devaluation at work through social stressors has been linked to various detrimental outcomes. 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. Theoretical and practical implications as well as limitations and avenues for future research are discussed.

These rules are universal and widely accepted by chemists worldwide, but their complexity makes it challenging for individuals to consistently apply them accurately. A translation method can be employed to address this challenge. 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. While established deterministic algorithms remain the gold standard for systematic chemical naming, our work, enabled by access to OpenEye’s Lexichem software through an academic license, demonstrates the potential of neural approaches to complement existing tools in chemical nomenclature.

April 2024, Chambéry, France N2 - The precision of yield calculation of modern design and simulation software for photovoltaic systems strongly rely, beside the accuracy of the specified module and inverter data, on the quality of the weather data. Since data from weather stations is not available for most locations world-wide this data is calculated by using modern interpolation methods. Beside this, simulation software typically uses historical weather data. 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. The second largest sources for simulation mismatches are power calculation and module temperature correction.

Dabei liegt der Fokus auf dem Einsatz dieser Technologien in der Malwareanalyse oder der Angriffserkennung im Kontext einer EDR-Sensorik. Es werden die grundlegenden Konzepte und Begriffe Systemvirtualisierung eingeführt, erklärt und zu verwandten Gebieten abgegrenzt. Der Weg über die Erweiterung bestehender Schutz-Konzepte moderner CPUs und Betriebssysteme wird beschrieben hin zu Befehlssatzerweiterungen, welche die Hypervisor-Software bei der Bildung der Abstraktionsebenen unterstützen. Dabei wird die Verwendung der Virtualisierungserweiterungen VT-x und AMD-V für die IA32/AMD64-ISA erklärt einschließlich verschiedener Methoden zur Virtualisierung des Paging-Systems. Ein besonderer Fokus liegt dabei auf dem „Second Level Address Translation“-Konzept (SLAT). Neben der Betrachtung der PC-Prozessoren wird auch die Virtualisierungsfunktionalitäten der ARMv8-Architektur erläutert und deren Verwendung beispielhaft beschrieben. Im Kontext der Malwareanalyse und Angriffserkennung ist es besonders relevant, dass Virtualisierungs- und Analyseumgebungen nicht erkannt werden können.

N2 - This work is the result of an exploration of the topics ardware-assisted full virtualization, virtual machine introspection (VMI) and VM detection mechanisms included prevention techniques. The fokus is on the use of these technologies for malware analysis or EDR sensors. The basic concepts and terms of virtualization are explained and delimited from related terms. The evolution from protection concepts of modern CPUs and operating systems to instruction set extensions for virtualization is shown. The use of the virtualization extensions VT-x and AMD-V is explained. This also includes methods for virtualizing the paging system like shadow page tables and hardware features for second level address translation like EPT and RVI. In addition the use of the virtualization functionalities of the ARMv8-ISA are explained. In the context of malware analysis and EDR sensors, it is particularly relevant that virtualization and analysis environments cannot be detected by malware. Various detection approaches and methods to bypass them are described. In order to analyze malware in an unobserved way, the analysis via virtual machine introspection (VMI) techniques is recommended. The functionality and challenges of VMI are described. The main issue is the semantic gap problem, which is explained and possible ways to deal with it are given. Furthermore some important VMI libraries and thechniques are described. A brief consideration of two sample virtualization solutions concludes the work. These are Drakvuf as an example of a malware analysis sandbox based on VMI and SimpleVisor, a minimal model hypervisor that uses hyperjacking.

(gmds) 2024 in Dresden, Germany Studies in Health Technology and Informatics, Bd. 317 N2 - Introduction: Drawing tasks are an elementary component of psychological assessment in the evaluation of mental health. 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.

Seville, Spain. 11-13 November, 2024. N2 - When organizing intercultural and interdisciplinary Project-Based Learning (PBL) activities across Higher Education Institutions (HEIs), the organizational and resource implications, along with the associated financial challenges, soon become crucial. Even promising approaches may not take off as a simple ‘return on investment’ view and funding decision may not fully address their various impacts on students, staff, institutions and society. This paper explores the experiences within a distributed interdisciplinary project-based learning program run from 2020 to 2023 and involving more than 150 students from four continents learning 21st century skills by collaborating over one semester to address real-world problems faced by clients in partner countries. While the primary goal of this distributed interdisciplinary and intercultural project-based learning program was to offer students a truly Global Intercultural Project Experience (GIPE), this paper explores its broader impact. We found that the program significantly influenced both the academic and administrative staff at all partner universities. Furthermore, we examine the program's effect on the participating institutions themselves over the four-year period. Our conclusion is that the invaluable benefits of such interdisciplinary project-based learning extend well beyond financial metrics. They include enhanced student learning experiences, strengthened cooperation and mutual learning between academics and administrative staff, improved institutional reputation, and positive societal impact. Thus, we worked hard to convince both our university management and the world's largest funding organisation for the international exchange of students and researchers to grant financial support for another 3-year period in 2025 to 2027 during which the GIPE concept will be further developed and a permanent organizational structure shall be established based on an extended network of partner institutions and sponsors around the world.

Over the past decades, efforts have ranged from automated advisors to Intelligent Tutoring Systems, all aimed at tailoring learning experiences to students' individual needs and interests. Unfortunately, many of these endeavors remained largely theoretical or proposed solutions challenging to implement in real-world scenarios. However, we are now in the era of Large Language Models (LLMs) like ChatGPT, Mistral, or Claude, which exhibit promising capabilities with significant potential to impact personalized education. For instance, ChatGPT 4 can assist students in using the Socratic method in their learning process. Despite the immense possibilities these technologies offer, limited significant results are showcasing the impact of LLMs in educational settings. Therefore, this paper aims to present tools and strategies based on LLMs to address personalized education within online collaborative learning settings. To do so, we propose RAGs (Retrieval-Augmented Generation) agents that could be added to online collaborative learning platforms: a) the Oracle agent, capable of answering questions related to topics and materials uploaded to the platform.; b) the Summary agent, which can summarize and present content based on students' profiles.; c) the Socratic agent, guiding students in learning topics through close interaction.; d) the Forum agent, analyzing students' forum posts to identify challenging topics and suggest ways to overcome difficulties or foster peer collaboration.; e) the Assessment agent, presenting personalized challenges based on students' needs. f) the Proactive agent, analyzing student activity and suggesting learning paths as needed. Importantly, each RAG agent can leverage historical student data to personalize the learning experience effectively. To assess the effectiveness of this personalized approach, we plan to evaluate the use of RAGs in online collaborative learning platforms compared to previous online learning courses conducted in previous years.

For the years 2020 until 2023, we received seed-funding for four annual projects to engage students from Germany (Europe), Namibia (Africa), Indonesia (Asia), and Peru (Latin-America) to collaborate over one semester on interdisciplinary projects contributing to the solution of some real-life client’s problems in the partner countries. During this period, more than 150 students embarked on these projects with 116 of them being selected for a scholarship for an international mobility. With the guidance and support by academics from all partner universities, the students success-fully completed each project expressing deep appreciation for the learning opportunities while over¬coming challenges of working across widespread time zones, different cultures, changing requirements, and various technical difficulties. While the primary aim of this distributed interdisciplinary and intercultural project-based learning program was to provide students with a truly Global Intercultural Project Experience (GIPE), in this paper we investigate on its impact in a broader sense as it was observed that this program also had a significant impact on both academic and administrative staff at all partner universities. Finally, we also reveal the impact of this four-year-program on the participating institutions themselves and conclude that the invaluable returns of such interdisciplinary project-based learning extend far beyond financial metrics. It encompasses enhanced student learning experiences, strengthened cooperation and mutual learning between academics and administrative staff, as well as institutional reputation, and societal impact.

The journalistic business model is losing sales, and the decline in print circulations is making it successively difficult to earn money with journalistic products. Therefore, german media companies have been investing in business models that have no relation to journalism to generate growth for years – with success. Considering this development, it is astonishing from a purely economic perspective that media groups, which are increasingly developing into technology companies, are still clinging to the ailing journalistic business model at all. To examine their motives to do so, this study poses the following research question: "Why do media companies still invest in journalistic products today?" To answer it, the researcher conducted interviews with highlevel employees from media companies as part of a qualitative study. Analysis of the data revealed that media companies continue to invest in journalism mainly because they benefit economically from the brands their journalistic products represent. Other reasons like serving as a pillar of the democratic constitution or to help shape public discourse seem to be less important.

Spherical morphologies were identified at pH 0, shifting towards honey-combed structures at pH 4 with increasing surface area, especially at pH 3. Further, the electrolyte pH was found to influence the NiFe composition and electro-catalytic activity. Enhanced OER activity was noted at pH 2 with overpotentials of 214 mV at 10 mA cm−2 and 267 mV at 100 mA cm−2. The results reveal that the electrolyte pH is a parameter not only influencing the morphology but also tailoring the surface area, Fe oxide and Fe hydroxide composition and consequently the catalytic activity. Further, the outcomes highlight the electrolyte pH as a key process parameter that should be adjusted according to the application, and may substitute the addition of electrolyte-additives, proposing a simpler method for improving catalyst electrodeposition.

It highlights the transition to improved patient engagement and better health outcomes facilitated by these technologies, underscoring the importance of ultra-reliable, low-latency communications (URLLC) and realizing the tactile Internet’s potential in healthcare. This innovation could dramatically transform telemedicine and mobile health (mHealth) by enabling remote healthcare delivery while providing a better understanding of the inner workings of the patient. 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.

Die Steckbriefe umfassen die auftretenden Leistungsverläufe der Versorgung aus Photovoltaik, Windkraft, Biomasse usw. und des Verbrauchs mit Stromdirektverbrauchern, Wärmepumpen und Elektro-Fahrzeugen. Für den Verbrauch werden zwei Lastvarianten angegeben. Elektrolyseure sind in beiden Varianten nicht berücksichtigt, 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 Leistungsverläufe werden ergänzt durch „Heatmaps“, mit deren Hilfe sich die Leistungsverläufe in vorteilhafter Weise tages- und stundenweise auflösen lassen. Im Gegensatz zur normalen Darstellung der Leistungsverläufe, aus denen sich saisonale Leistungsgänge und Leistungswerte sehr gut ablesen lassen, lassen sich aus diesen Heatmaps auch Tagesgänge aufgrund menschlicher Verhaltensweisen ermitteln. Statistiken zur Verteilung der Leistungswerte und Tabellen mit den wichtigsten Eckwerten der entsprechenden EE-Erzeuger und Verbraucher vervollständigen die Steckbriefe. In Einzelfällen werden noch Zusatzerläuterungen gegeben, ohne die sich die entsprechenden Steckbriefe unvollständig wären. Insgesamt ergibt sich, dass der Stromverbrauch ab 2045 saisonal enorm ausgeprägte Maxima und Minima aufweist, die erheblich von den Maxima und Minima des heutigen Stromverbrauchs abweichen. Dies ist das Resultat des Stromverbrauchs aus Wärmepumpen und Elektro-Fahr-zeugen. Die Verbrauchsmaxima können 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 benötigt, dessen kontinuierliche Verfügbarkeit während eines Tages größer wie 2 Stunden sein muss. Er muss gezielt zur Morgenzeit, typischerweise zwischen 05:00 und 07:00, mit Leistungshüben von 20 GW/h eingeschaltet und abends, typischerweise zwischen 18:00 und 20:00, mit Lastabwürfen von über 22 GW/h gezielt wieder abgeschaltet werden können. Grund hierfür ist der Wechsel menschlicher Tagesaktivität auf Nachtpassivität und umgekehrt, was sich im täglichen Strombedarf widerspiegelt.

N2 - Deutschlands Stromversorgung soll im Jahr 2045 gemäß aktueller Planung (z.B. EEG 2023) aus-schließlich mit Hilfe sog. erneuerbarer Energien geschehen. Hierzu gehören Wind- und Solar-kraft und in erheblichst geringerem Maße Biomasse- und Laufwasserkraft. Bekannt ist, dass die Energiezufuhr aus diesen Energiequellen überwiegend volatil und daher inkompatibel mit dem Strombedarf der Verbraucher ist. Ohne weitere Maßnahmen käme es ständig zu Über- oder Unterversorgungssituationen mit der Folge dauerhafter Blackouts. Während eine Überversorgung im einfachsten Fall mit dem rechtzeitigen, wenn auch unwirtschaftlichen Abschalten der entsprechenden Energieversorger sehr gut beherrschbar ist – andere Maßnahmen sind die Speicherung der überschüssigen Energie oder deren Export, sofern es das Ausland zulässt –, ist die Darstellung der Versorgungssicherheit im Falle einer Unterversorgung, also die Vermeidung ewiger Blackouts, nur mit Hilfe zusätzlicher aktiv steuerbarer Energiequellen darstellbar. In Frage kommen hierfür nach heutiger Diskussionslage Gas- bzw. H2-Kraftwerke, virtuelle und reale Batterie-Kraftwerke, sowie Pumpspeicher-Kraftwerke und Stromimporte. Für den Import muss das Ausland für Deutschland regelbare Kraftwerke vorhalten, die stets dann mit erster Priorität bereitstehen müssen, wenn Deutschland in eine Unterversorgungslage gerät. Diese Möglichkeit erscheint dem Berichter eher spekulativ als gesichert. Die Verwendung deutscher Kernkraftwerke wird heutzutage aus politischen Gründen negiert, während gleichzeitig und widersinnigerweise der Import ausländischen Kernkraftstroms billigend in Kauf genommen wird.

Das Strommarktdesign solle einen Paradigmenwechsel im Strommarkt herbeiführen. Eingeführt werden soll ein Kapazitätsmarkt, eine Art systemische Grundgebühr, zur Finanzierung unwirtschaftlicher Investitionen in künftig nur wenig auslastbare Kraftwerke. Zudem sollen die Stromverbraucher als Regelkomponente in einer zukünftig 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 unterfüttern und erweitern diese Untersuchung mit Blick auf die erhoffte Beeinflussbarkeit des künftigen, den politischen Energiewende-Planungen unterworfenen Stromversorgungssystems. Die Untersuchungsergebnisse werden wie folgt interpretiert: • In „Smart-Grids“ können dynamische Stromtarife das Verbraucherverhalten bei einem Einsparpotential von 10 bis 15% begrenzt beeinflussen. • Der Einfluss beschränkt sich auf lokale Stromversorgungsnetze. • Der Stromverbrauch wird in dem Sinne vergleichmäßigt, dass tageweise auftretende Lastspitzen und Lasttäler sich durch Lastverschiebungen ausgeglichener darstellen. Die Differenz der beiden Tagesextremwerte könnte um bis zu 20% sinken. • Der jährliche Stromverbrauch wird hierdurch nicht wahrnehmbar beeinflusst. Der qualitative Verlauf des Lastgangs ebenso wenig. • Die Vergleichmäßigung ist in dem Sinne netzdienlich, dass nur unzureichend ausgebaute Ortsnetze durch die künftige zunehmende Beanspruchung durch Elektromobilität und Wärmepumpen nicht überbeansprucht werden bzw. dass deren sowieso notwendiger Ausbau in etwas reduzierter Weise ausgeführt werden kann. • Die grundlegenden Probleme bzw. Herausforderungen des geplant volatilen Gesamtstromversorgungssystems lassen sich durch Einsatz der Stromverbraucher als system-dienliches Regelglied nicht lösen. Dazu ist ihre Wirkung im Vergleich zur über das Jahr gemittelten Last zu gering. Der gewünschte Ausgleich sollte besser mit Hilfe geeigneter Speicher statt mit humanen Ressourcen als Regelglied gelöst 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 häufiger zutage tretenden, bisher noch verkraftbaren Dysfunktionalitäten der derzeitigen Stromversorgung durchaus in Betracht gezogen werden.

Die frühe Erkennung von Angriffen und der Ausführung von Schadsoftware auf Windows-Clients bedingt Sensor-Technologien, die Systemereignisse erkennen und protokollieren. Anhand bestimmter Ereignisse oder komplexerer Ereignismuster können illegitime Vorgänge auf Computersystemen erkannt werden. Der Fokus dieser Arbeit liegt darauf einen detaillierten Überblick über diese ereignisbasierte Sensorik für Windows-Endpunkte zu geben, die Systemereignisse erkennt und Ereignis-Objekte mit beschreibenden Attributen liefert. Im Gegensatz dazu wird die Interpretation der bereitgestellten Ereignisdaten und der Musterabgleich in dieser Arbeit nicht behandelt. Zu Beginn werden dafür die elementaren Aspekte und Begriffe einer solchen Sensor-Technologie allgemein erklärt. Dabei werden einige charakterisierende Grundeigenschaften erläutert, anhand derer solche Senor-Verfahren eingeordnet werden können. Zudem wird auf Basis durchgeführter Messungen eine Abschätzung bezüglich der Auftrittsfrequenzen verschiedener Systemereignisse geliefert. Im Hauptteil werden die zwei ereignisbasierten Monitoring-Systeme Event-Tracing-for-Windows (ETW) und Sysmon vorgestellt. Die Funktionalität, Architektur und interne Funktionsweise der beiden Systeme wird detailliert erläutert. Zudem werden ihre charakterisierenden Basiseigenschaften herausgearbeitet, um Stärken und Schwächen zu erkennen. Der ETW-basierte Sensor und SIGMA-Regelscanner Nextron Aurora, der Sysmon-ähnliche Ereignisdaten bereitstellt, wird ebenfalls behandelt. N2 - This thesis is an overview of the topic of event based monitoring of Windows PCs. The early detection of cyberthreat attacks and malware execution on Windows clients requires sensor technologies that detect and log system events. Certain events or more complex event patterns can be used to detect illegitimate behavior on computer systems. The focus of this thesis are these event-based sensors for Windows endpoints, which detect system events and provide event objects with descriptive attributes. The interpretation of the provided event data and pattern matching are not covered in this work. At the beginning, the elementary aspects and terms of such a sensor technology are explained in general. This includes some characterizing basic properties, which can used to classify such sensor technologies. In addition, some estimates of the trigger frequencies of various system events based on own measurements are reported. The two event based monitoring systems Event Tracing for Windows (ETW) and Sysmon are presented in the main part. The usage, functionality, architecture and internals of the two systems are explained in detail. Moreover, their most significant characterizing properties are expounded in order to identify advantages and disadvantages. The ETW based sensor and SIGMA rule scanner Nextron Aurora that provides Sysmon like event data is also covered.
