Das ökonomische und ökologische Potenzial, dass sich aus der Nutzung der Synergien dieser Komponenten ergeben kann, erfordert eine gemeinsame Betrachtung des gesamten Energiesystems hinsichtlich sämtlicher Energie- und Verbrauchssektoren. Die Energiesystemmodellierung stellt eine geeignete Methode zur Modellierung und Optimierung dieser urbanen Energiesysteme dar. Mit dem „Spreadsheet Energy System Model Generator“ (SESMG) hat die FH Münster ein Open Source Tool entwickelt, das die Betrachtung urbaner Quartiere ermöglicht. Diese können hinsichtlich verschiedener Zielkriterien wie z. B. monetären Kosten und THG-Emissionen optimiert werden. Die tabellenbasierte Eingabe erfordert keine Programmierkenntnisse. Das implementierte Urban District Upscaling Tool erleichtert die effektive Modellierung auch größerer Systeme. Die automatisierte Ergebnisaufbereitung ermöglicht eine schnelle Analyse der Ergebnisse.

Nicht selten ist dieser erschwerte Umgang auf (unnötiges) eigenes Komplizieren, Fehlinterpretieren oder auch auf das Zurückgreifen auf sogenannte Abkürzungsstrategien (Heuristiken) zurückzuführen. Dieser Arbeitsbericht beschäftigt sich genau mit diesem zugrundeliegenden Verhalten und erläutert mit zahlreichen konkreten Beispielen den vielfach anzutreffenden realen Entscheidungsprozess. Zunächst werden zentrale Grundbegriffe erläutert, um ein einheitliches Verständnis zu gewährleisten. Mit diesem Verständnis wird auf verschiedene Grundlagen von Wahrscheinlichkeiten wie auch Statistiken eingegangen, um ein wissens- und verständnisbasiertes Fundament für die weiteren Teile dieses Arbeitsberichts sicherzustellen. Im zweiten Kapitel werden sowohl ausgewählte Heuristiken (kognitive Abkürzungsstrategien) als auch systematische Fehler beim Umgang mit Wahrscheinlichkeiten vorgestellt und erläutert. Im Anschluss werden ausgewählte und typische Paradoxien beschrieben, die zum einen im Bereich von Wahrscheinlichkeiten und Statistiken und zum anderen im Bereich von Entscheidungen auftreten können. Zuletzt werden die Ansatzpunkte einer Manipulation von Statistiken dargestellt.

The objective is to answer the question whether CMS are effective, and to consider the limits of compliance. For this purpose, the highly legalistic topic is considered in the context of business ethics and behavioural economic foundations. The review of effectiveness is based on the seven basic components set out in the Assurance Standard of the Institut der Wirtschaftsprüfer in Deutschland e. V. [Institute of Public Auditors in Germany, Incorporated Association] (IDW AssS 980). To answer this question, reference is made to the three levels of business ethics and to selected behavioural economics concepts. For example, performance pressure, peer pressure and variable compensation schemes encourage opportunistic behaviour. It is argued that corporate compliance depends significantly on the behaviour of single individuals and their environment. Especially in the context of economic activity and competition, compliance cannot be equated to morality and ethics, or be expected as a matter of course. On the whole, the interdisciplinary consideration of corporate compliance demonstrates a natural limit whenever ethical and moral standards are contrary to economic interests.

Die Basis der Wirksamkeitsprüfung stellen die sieben Grundelemente des Prüfungsstan-dards des Instituts der Wirtschaftsprüfer in Deutschland e. V. (IDW PS 980).Die drei Ebenen der Wirtschaftsethik sowie ausgewählte Konzepte der Verhaltensökonomie werden zur Untersuchung aufgegriffen. So begünstigen etwa Leistungs- und Gruppendruck sowie variable Vergütungssysteme opportunistische Verhaltensweisen. Es wird dargelegt, dass unternehmerische Compliance signifikant vom Verhalten einzelner Individuen und ihrem Umfeld abhängt. Insbesondere im Kontext wirtschaftlichen Handelns und Wettbewerb kann Compliance nicht mit Moral und Ethik gleichgesetzt oder als Selbstverständlichkeit erwartet werden. Insgesamt bescheinigt die interdisziplinäre Betrachtung der unternehmerischen Com-pliance immer dann eine natürliche Grenze, wenn ethisch-moralische Ansprüche konträr zu ökonomischen Interessen stehen.

Diese Tatsache beschränkt sich nicht nur auf vermeintlich einfache Situationen, auch komplexe Entscheidungen werden durch unsere Emotionen gelenkt. Doch wie stark werden wir durch sie beeinflusst? Um dieser Frage auf den Grund zu gehen, wird in diesem Arbeitsbericht der Entscheidungsprozess anhand der Prospect Theory von A. Tversky und D. Kahneman dargestellt. Anschließend werden die Emotionen und daraus resultierende Heuristiken und Biases beschrieben. Oft werden Alternativen so schon früh im Entscheidungsprozess ausgeschlossen, ohne dass wir es überhaupt mitbekommen. Einige anschauliche Beispiele werden diese Tatsache verdeutlichen. Nach einer tiefgreifenden Betrachtung des besonderen Gefühls „Glück“ werden schlussendlich kurze wissenschaftliche Handlungsalternativen zur glücksbringenden Entscheidungsfindung aufgezeigt.

Das gilt für die Privatwirtschaft ebenso wie für öffentliche oder Non-for-Profit-Institutionen. Damit stellt das Prozessmanagement seit jeher eine zentrale Herausforderung der Organisationsgestaltung dar. Im Rahmen der Technifizierung von betrieblichen Abläufen entwickelten sich in den vergangenen Jahrzehnten hervorragende Informationssysteme, welche die Mitarbeiter mit Daten versorgten, die in definierten Sequenzen genutzt bzw. weiterverarbeitet wurden. Die Logik lag im Informationssystem. Damit wurde Mitarbeitern jedoch viel von ihrer Entscheidungskompetenz genommen. Andererseits ist es im Umfeld strategischer Entscheidungen oder auch im Projektmanagement noch immer nicht gelungen, Entscheidungsträger bzw. Projektmanager substantiell und zielgerichtet mit dem richtig dosierten Wissen am Ort des Bedarfs zu unterstützen. Insgesamt ist festzustellen, dass die Menschen an ihren Arbeitsplätzen häufig nicht die Möglichkeit haben, ihr Fach-, Methoden- und Erfahrungswissen in der Form einzubringen, wie sie es könnten. Und mit Bezug zum Gesamtunternehmen fehlt die Möglichkeit dieses Wissen kollektiv verfügbar zu machen. Durch die Entwicklung sozialer Medien auf Basis der Internettechnologie wurden erstmals die Voraussetzungen geschaffen, nicht nur das erforderliche Wissen in die betrieblichen Abläufe auf jeder Unternehmensebene zu bringen. Darüber hinaus sind nun die Möglichkeiten gegeben, tatsächlich die seit den 80er-Jahren geforderte „Lernende Organisation“ auszugestalten. Enterprise-Wikis bilden eine Plattform für das prozessorientierte Wissensmanagement. In diesem Arbeitsbericht sollen das dahinterliegende Konzept sowie die Erfolgsfaktoren des praktischen Einsatzes vorgestellt werden. Basierend auf dem fiktiven Unternehmen der „Nordwalder Maschinenbau GmbH & Co. KG“ werden Ergebnisse aus der Forschung am Institut für Technische Betriebswirtschaft (ITB) sowie aus konkreten Umsetzungsprojekten in der Unternehmenspraxis vorgestellt und diskutiert. So erhalten Führungskräfte einen Einblick in die Potenziale, die sich daraus auch für ihre Organisation ergeben können.

Dabei wurde der Fokus vor allem auf die Einführung der bekannten Lean-Methoden und Tools gelegt. Was passiert jedoch, wenn die Organisationsstruktur und Führungskultur nicht angepasst werden? Sind die eingeführten Lean Methoden dann immer noch erfolgsversprechend? Es wird die These aufgestellt, dass wenn Lean nur auf die bekannten Lean-Methoden reduziert wird, das Unternehmen keinen nachhaltigen Wettbewerbsvorteil generieren kann. Es lassen sich allgemeingültige Tendenzen westlichen Führungsverhaltens erkennen, welche in dieser Arbeit herausgearbeitet und dem japanischen Führungsverhalten gegenübergestellt werden. Dabei wird deutlich, dass einige Aspekte der Führungskultur dem Lean-Gedanken widersprechen und Grund für den mangelnden Erfolg westlicher Unternehmen mit einem schlanken (leanen) Produktionssystem sein könnten. Es wird somit die Forschungsfrage gestellt, was ein Unternehmen benötigt, das bereits ein schlankes Produktionssystem eingeführt, jedoch die konventionellen Führungsmuster beibehalten hat, um das Produktionssystem erfolgreich nutzen und weiterentwickeln zu können mit dem Ziel aus „Lean Management“ einen langfristigen Wettbewerbsvorteil zu generieren. Es werden hierzu verschiedene Lösungsansätze diskutiert. Zum einen wird die Möglichkeit vorgestellt, eine Arbeitsorganisation nach dem Vorbild Toyotas einzuführen. Des Weiteren werden Ansätze erläutert, das Potenzial der Mitarbeiter, die jeden Tag am Prozess arbeiten, besser einzubinden und für tägliche Verbesserungen zu nutzen. Außerdem wird ein erweitertes Führungsverständnis vorgestellt, bei dem Führungskräfte täglich den Ort der Wertschöpfung aufsuchen und als Coach auftreten, um langfristig eine lernende Organisation zu erzeugen. Aus der Analyse ergibt sich, dass die Führungskraft die zentrale Rolle spielt, um einen langfristigen Wettbewerbsvorteil aus Lean Management zu generieren. Aus diesem Grund werden vier Aufgaben für Führungskräfte im direkten1 Bereich definiert, die täglich durchgeführt werden müssen. Das Führungsziel ist hierbei, alle Mitarbeiter in der Masse zu befähigen, das Unternehmen täglich zu verbessern und jeden Tag individuell und als Organisation zu lernen. Um den Erfolg dieses Ansatzes zu verifizieren, wurden die Aufgaben mithilfe der BMW Group in einem Fertigungsbereich in München entwickelt und getestet. Die Aufgaben lauten „Prozesse beobachten und bestätigen“, „Probleme strukturiert lösen“, „Kontinuierliche Verbesserung treiben“ und „Mitarbeiter befähigen“, welche täglich gemäß eines Stundenplans von allen Führungskräften im Pilotbereich durchgeführt werden. Dabei führt die Führungskraft die Aufgaben selbst durch und tritt als Coach für die jeweils untere Hierarchieebene auf. Mithilfe eines Bewertungstools, das eine Selbst- und mehrere Fremdeinschätzungen enthält, konnte der Ist-Zustand sowie die Verbesserungen des Führungsverhaltens gemessen und der Erfolg verifiziert werden. Abschließend kann gesagt werden, dass durch das Aufbauen der relevanten Kompetenzen bei den Führungskräften, Multiplikatoren einer förderlichen Führungs- und Verbesserungskultur geschaffen werden können. Mit den Standardaufgaben arbeiten alle Mitarbeiter und Führungskräfte täglich an der Weiterentwicklung des Produktionssystems, indem sie Probleme lösen und Prozesse verbessern. Die Organisation kann sich entwickeln und lernen, was als nachhaltiger und langfristiger Wettbewerbsvorteil gesehen werden kann.

This paper mainly focuses on analyzing this potential. Field tests were conducted to investigate the irrigation behavior and the storage effect of a storm water tree pit system using Perl hoses as irrigation elements over a period of two years. The rainfall, storage volumes, and soil moisture within the employed planting pit were measured. With the help of system modeling, the retention ability of the storm water tree pit system was analyzed. The available storage volume was sufficient to irrigate trees for several days. During the measurement period, about 15% of the inflowing rainwater was fed to the root zone of the tree. With practical storage volumes of 200 to 300 m3/ha, a remarkable amount of water from heavy rainfall could be completely stored, thus significantly reducing the risk of flooding. The retention effect and irrigation behavior largely depend on the soil conditions and the technical possibilities of the equipment supplying the root area (in this case, Perl hoses). Further investigations are required to determine the influence on the growth conditions of trees and optimize of the system for discharge into the root zone.

The first two energy-weighted sum rules are shown to be fulfilled independent of the interpolating function for any selfenergy. For various models of one-dimensional Fermions scattering with impurities the quality of the Pad´e approximation for the spectral function is demonstrated and the reduced density matrix or momentum distribution is reproduced not possessing a jump at the Fermi energy. Though the two-fold expansion is necessary to realize the spectral function and reduced density, the extended quasiparticle approximation itself is sufficient for the description of transport properties due to cancellation of divergent terms under integration. The T-matrix approximation leads to the delay time as the time two particles spend in a correlated state. This contributes to the reduced density matrix and to an additional part in the conductivity which is presented at zero and finite temperatures. Besides a localization at certain impurity concentrations, the conductivity shows a maximum at small temperatures interpreted as onset of superconducting behaviour triggered by impurities. The Tan contact reveals the same universal behaviour as known from electron-electron scattering.

To publish in this journal, it is a premise to take part in the master course wind power, hydro power and biomass usage at the department of Energy, Building Services and Environmental Engineering of the Münster University of Applied Sciences. Students receive an equivalent of 2.5 credit points (European Credit Transfer and Accumulation System – ECTS) for their engagement in the course and for publishing a short review article of at most 3 000 words in this periodical. The publication process closely mimics the typical publication procedure of a regular journal. The peer-review process, however, is conducted within the group of course-participants. Although being just an exercise, we think that publishing the outcome of this course in a citable manner is not only promoting the motivation of our students, but may also be a helpful source of introductory information for researchers and practitioners in the field of renewable energies. We encourage students to write their articles in English, but this is not mandatory. The reader will thus find a few articles in German language. To further encourage students practicing English writing, perfect grammar is not part of the assessment. We especially thank our students for working with LATEX on Overleaf, although LATEX is new to some of them. In this way, the editorial workload was reduced to a minimum. We also thank our students for sharing their work under the creative commons attribution licence (CC-BY). We appreciate their contribution to scientific information, being available to every person of the world, almost without barriers.

Its expansion is therefore important in order to achieve the climate targets. Repowering is an important element in the expansion of wind energy. On the one hand, it offers a solution for many wind turbines in Germany that are no longer subsidised due to their age. On the other hand, modern turbines are significantly more powerful and enable more efficient land utilisation. This article provides an overview of the most important aspects of onshore repowering. There is a lot to consider when repowering wind turbines. The legal situation for repowering aims to be improved through simplified authorisation procedures. Even though efforts are being made by the government, there is still room for improvement. The repowering potential is also dependent on the various distance regulations to residential buildings in the federal states. These regulations might also be improved in the future. Another aspect is the remuneration, which is now closer to market developments due to the market premium model. It is also subject to greater competition as a result of the tendering process. At the same time, interest rates and turbine prices have risen, which creates economic challenges for the operators of future wind farms. Last but not least, repowering also depends on public acceptance. This is also to be regulated by law in the future.

After a thorough examination of the literature, it was concluded that although the impact on bird populations is significant, it may be overemphasized in popular debates. This statement is not final as further research is necessary to assess the impact of bird strikes and explore new solutions. Comprehensive studies on this specific topic in Germany are limited, which makes a thorough evaluation challenging. While there are measures in place to protect species that may be negatively impacted, it is possible that these measures will not be adequate for all of them. While several innovative methods are under examination, progress in testing and implementation is slow. Lastly, an information problem was identified. Since the topic is highly politicized and polarizing, it is crucial to provide the public with accessible and reliable information on the discussed themes. This is currently not the case due to a lack of data and missing information campaigns.

Various challenges arise when it comes to upscaling. This article summarizes the technical challenges associated with upscaling wind turbines and presenting their problem-solving approaches and research trends based on other reviews. It was found that the most frequently cited challenges are related to individual components, such as rotor blades, drive train, generator, tower, and noise impact. For rotor blades, the challenges are increased flexibility, more aeroelastic vibrations, increased wear, interferences with radar and transportation difficulties. Proposed solutions include the use of carbon-fiber blades, prebending, novel paints, and for transportation, segmented rotor blades and on-site manufacturing. In the gearbox, torque increases, leading to higher weight and susceptibility to errors. As a result, the trend is moving towards gearless systems with permanent magnet synchronous generators. Transportation is the major issue with towers, which can be resolved with on-site manufacturing. In terms of noise emission, reducing aerodynamic noise plays the most significant role.

As the world’s reliance on renewable energy, particularly offshore wind, increases to reduce climate change, the growing number of OWTs requires effective O&M. Challenges consist of logistics, accessibility and high costs. The paper presents the application of climbing robots, unmanned aerial vehicles and underwater robots to overcome these challenges. The combination of multiple robotic platforms, such as autonomous surface vehicles and autonomous underwater vehicles, represents a collaborative approach to O&M. Obstacles include the need for accurate navigation, building trust between humans and robots, and research into artificial intelligence. In conclusion, the integration of robotics in O&M presents considerable advantages, increasing efficiency, safety and cost-effectiveness. Further progress and research into artificial intelligence are crucial in achieving complete automation, which will transform the O&M of OWTs.

The main objective was to conduct a market analysis to assess the marketability of these wind energy systems. The aim was to make it easier for potential customers to make a decision. However, due to the limited availability of data, the project encountered considerable difficulties. As a result, the study became a comparative assessment, which led to results that may not be readily transferable to urban environments, slightly missing the original objective of the study. The results underline the difficulties associated with conducting a comprehensive market analysis in this sector and highlight the need for an independent series of tests under specific conditions. The paper concludes with a plea for future research efforts to adapt data collection methods to urban conditions in order to improve the relevance and applicability of such studies in practice.

In the context of this paper, energy recovery in the outlet of wastewater treatment plants is examined using the specific example of the water wheel at the Warendorf central wastewater treatment plant. The ”artificial” hydropower potential can be roughly estimated at up to 20 to 105 GWh/a , whereby this is largely dependent on the hydraulic gradient. The strong variance results, among other things, from the findings of the water wheel operation in Warendorf. The decisive aspect here is the differential factor, which describes the deviation between the theoretical and actual energy yield of the water wheel. The factor includes maintenance work, downtimes and insufficient inflows, which are associated with a loss of output. In the case study, the annual energy recovery amounts to approx. 2 % of the annual electricity consumption of the wastewater treatment plant and can be estimated to 23,500 kWh (2022). In the context of the economic analysis, it can be seen that despite the ”low” yield, economic operation is possible if the system is viewed as a long-term investment - payback period of the example is approx. 14,5 years. The 27-year operation (1996 - 2023) of the water wheel at the Warendorf central wastewater treatment plant confirms this and important findings on successful practical operation can be shown in the context of this paper.

Various structures impede watercourse continuity, impacting fish migration and habitat distribution. Conventional fish passages often fall short in diverse scenarios, prompting the development of specialized solutions. This article proposes a criteria catalog for these special fish passage solutions based on DWA leaflet DWA-A 509. It discusses the need for these solutions, presents a selection of specialized options, and outlines criteria from DWA-M 509, construction guidelines, and economic perspectives. It scrutinizes criteria ranging from target fish species to cost considerations. Three examples, including the Runserau fish lift, the bristle ramp fish lock, and the Fishcon sluice, illustrate these specialized solutions, their functionalities, advantages, and drawbacks. Additionally, the article compiles criteria from industry standards and guidelines into a comprehensive evaluation catalog. The criteria, when applied, assist in the selection of suitable fish passage solutions based on specific site conditions and fish species requirements. This holistic approach aims to optimize fishway selection, fostering the ecological sustainability of watercourses. However, this catalog remains dynamic and open to expansion with evolving research and practical application, urging further exploration and validation of these criteria through diverse case studies and technological advancements in the field.

In recent years, the development and installation of wind turbines have seen rapid growth. However, with the increasing capacity and size of wind farms worldwide, there are growing concerns about the safety and reliability of these installations. Therefore, structural health monitoring and the detection of damage to wind turbines have gained considerable importance in research. Wind turbine blades are particularly susceptible to various types of damage due to environmental influences. This article provides an overview of signal responses, sensors used and non-destructive testing techniques in the field of damage detection on wind turbine blades. The intention of the article is to give an insight into the possibilities of structural health monitoring and at the same time to point out unsolved problems in this field.

However, these are also associated with environmental impacts. To that effect, this article takes a closer look at tidal power plants, which are classified as hydroelectric power plants, by conducting a systematic literature review. The results show that the strength and form of the environmental impact depends on the specific location and type of plant. Tidal power plants have an impact on the habitats of marine animals and thus influence their behavior and population. In addition, the operation of tidal power plants changes the sediment distribution, causes a reduction in current velocities and a change in current direction in the surrounding area and leads to a change in wave height. The construction of the power plants is associated with noise, which primarily causes changes in the behavior of some species. Furthermore, the electromagnetic fields generated can also affect marine life. In order to assess the environmental impact of tidal power plants in comparison to other renewable energies, further studies should focus on the environmental impact of the different technologies in relation to the energy yield.

Currently, this technology is still cost-intensive and mainly found in research. Here we propose one of the smallest fully integrated quantum sensors to date based on nitrogen vacancy (NV) centers in diamond microcrystals. It is an extremely cost-effective device that integrates a pump light source, photodiode, microwave antenna, filtering and fluorescence detection. Thus, the sensor offers an all-electric interface without the need to adjust or connect optical components. A sensitivity of 28.32nT/Hz−−−√ and a theoretical shot noise limited sensitivity of 2.87 nT/Hz−−−√ is reached. Since only generally available parts were used, the sensor can be easily produced in a small series. The form factor of (6.9 × 3.9 × 15.9) mm3 combined with the integration level is the smallest fully integrated NV-based sensor proposed so far. With a power consumption of around 0.1W, this sensor becomes interesting for a wide range of stationary and handheld systems. This development paves the way for the wide usage of quantum magnetometers in non-laboratory environments and technical applications.

A multi-criteria optimization model is used to minimize greenhouse gas (GHG) emissions and financial costs of a reference system. Sensitivity analyses examine the impact of changing boundary conditions related to GHG emissions, energy prices, energy demands, and population density. Options that align with both financial and emission reduction and are robust to system changes are called “no-regret” options. Options sensitive to system changes are labeled as “potential-risk” options. There is a conflict between minimizing GHG emissions and financial costs. In the reference case, the emission-optimized scenario enables a reduction of GHG emissions (-93%), but involves higher costs (+160%) compared to the financially-optimized scenario. No-regret options include photovoltaic systems, decentralized heat pumps, thermal storages, electricity exchange between sub-systems and with higher-level systems, and reducing energy demands through building insulation, behavioral changes, or the decrease of living space per inhabitant. Potential-risk options include solar thermal systems, natural gas technologies, high-capacity battery storages, and hydrogen for building energy supply. When energy prices rise, financially-optimized systems approach the least-emission system design. The maximum profitability of natural gas technologies was already reached before the 2022 European energy crisis.

Design/methodology/approach A quantitative research design was adopted for this study. The paper formulates hypotheses from the literature review. These hypotheses are tested using structural equation modeling with data collected from 231 SMEs in Uganda. Data were analyzed using SPSS version 23 and AMOS. Findings The findings of this study showed technology orientation has a positive and significant relationship with the performance of Ugandan SMEs and that supply chain agility moderates technology orientation and export performance. Research limitations/implications The study discusses the findings, advances limitations and managerial implications. It also suggests future research avenues. It proposes some recommendations to help Ugandan SMEs to form flexible supply chains, use the latest technology and create strong relationship ties with their partners in the supply chain. Practical implications The study suggests that managers of Ugandan SMEs should use the latest technology in production, marketing, logistics and supply chain management which will enable them to respond quickly to customer tastes and preferences leading to higher levels of export performance. Originality/value This study contributes to the literature on strategic management showing the reliability of scales used and the confirmatory of the factor structure.

Overall, 187 individuals from the general population aged ≥18 years were assigned to either the intervention group (IG; n = 112), receiving a 10-week intensive lifestyle intervention focusing on a healthy, plant-based diet; physical activity; stress management; and community support, followed by a 22-month follow-up phase including monthly seminars, or a control group (CG; n = 75) without intervention. The complete data sets of 118 participants (IG: n = 79; CG: n = 39) were analyzed. At baseline, total costs per person amounted to 67.80 ± 69.17 EUR in the IG and 48.73 ± 54.41 EUR in the CG per week. The reduction in total costs was significantly greater in the IG compared to the CG after 10 weeks (p = 0.012) and 6 months (p = 0.004), whereas direct costs differed significantly after 10 weeks (p = 0.017), 6 months (p = 0.041) and 12 months (p = 0.012) between the groups. The HLCP-2 was able to reduce health-related economic costs, primarily due to the reduction in direct costs.

The node on the path that drops these packets should respond with a Packet Too Big (PTB) message. However, multiple scenarios exist in which the sender will not receive a PTB message. Even if it does, it refrains from using the information in case it suspects that a potential attacker forged the message. In particular, we are not aware of any implementation of the secure transport protocol QUIC (e.g., used by HTTP/3) that processes PTB messages. In this paper, we present a novel parameterizable PTB detection algorithm for reliable transport protocols that does not depend on PTB messages. We further describe how to integrate our algorithm into QUIC, present results from an evaluation using the algorithm within a QUIC simulation model and, based on these results, suggest concrete parameter values.

However, to rely on information and decisions derived from model predictions, it is essential to establish model credibility for the specific context of use. Limited regulatory requirements and lack of consensus on the level of verification and validation activities required result in rare use of CMS as a source of evidence in the medical device approval process. The American Society of Mechanical Engineers (ASME) developed a risk-informed framework to establish appropriate credibility requirements of a computational model: the ASME V&V 40?2018 standard. This paper aims to outline the concepts of this standard and to demonstrate its application using an example from the orthotics field. The necessary steps to establish model credibility for a custom?made 3D printed wrist hand orthosis (WHO) are presented. It is shown that the credibility requirements of each verification and validation activity depend on model risk by applying two different contexts of use to the same computational model.

The Medical Device Regulation (MDR) is fully applicable since May 2021, strengthening the requirements for all stakeholders. As a result, many companies are facing enormous challenges. The aim of this study was to assess the impact of the MDR on the orthopaedic aids industry. Methods: Two surveys were conducted: one shortly before the MDR became applicable (146 respondents) and a second survey almost two years later (233 respondents). Results: Both surveys revealed that all businesses in the orthopaedic aids sector, regardless of size, have difficulty implementing the MDR. Key challenges include additional workload for technical documentation, increased resource expenditure and cost, and lack of clarity regarding the new requirements. Many companies are downsizing their product portfolio, resulting in potential supply shortages and a loss of competitive advantage and innovation for the medical device industry in Europe. Conclusions: The full extent of the MDR’s impact on clinical practice is still unclear. However, many companies lack the necessary resources. The MDR can potentially be a bottleneck in the availability of medical devices.
