''On February 6th, 2023, two severe earthquakes struck southeastern Türkiye near the Syrian border. The first earthquake, Mw7.8, occurred at 04:17 local time in the East Anatolian Fault Zone near the city of Gaziantep. The second earthquake, Mw7.5, occurred approximately 9 h later at 13:24 local time near Elbistan County, in Kahramanmaraş province. These seismic events ruptured multiple segments of the East Anatolian Fault Zone (EAFZ), with rupture lengths exceeding 300 km, and deformation exceeding 5 m on both sides of the faults. In this study, we aim to analyze characteristics of the strong ground motion induced by the mainshocks, focusing on ground motion intensity measures such as the peak ground acceleration (PGA), the peak ground velocity (PGV), and the pseudo-acceleration response spectra (PSA). The first earthquake produced extremely high PGA values in both horizontal (> 2 g) and vertical (> 1 g) components. At near field distances, large PGVs are measured (> 180 cm/s) with more than 30 impulsive motions which may indicate source-related effects. Large spectral demands are also recorded for both earthquakes, partially underestimated by Ground Motion Models (GMMs), especially in the near-field. Specifically, we compare the PSA for horizontal directions with the design spectra provided by both the new and previous Turkish building codes. We also present building and ground damage observations that provide insights into the observed ground motions in the heavily damaged areas.''

In werkpakket A, Zeewierteelt, werd onderzocht wat het effect is van de nitraatconcentratie op de groei en eiwitgehalte van de zeewiersoorten Saccharina latissima en Ulva lactuca. Bij de laatste soort werd ook gekeken naar de aminozuursamenstelling. Hogere nitraatconcentraties zorgden bij beide zeewiersoorten voor een hogere groeisnelheid en een hogere eiwitgehalte. De totale aminozuurhoeveelheid van Ulva lactuca was hoger bij blootstelling aan een hogere nitraatconcentratie. Alle gemeten aminozuurgehaltes waren hoger, behalve die van methionine, die gelijk was ten opzichte van de Ulva lactuca die gekweekt werd onder lage nitraatconcentraties. Het is dus mogelijk om tijdens het groeiproces, de aminozuur- en eiwitgehalte van zeewier te verhogen. De toename in eiwitgehalte was zelfs zo snel, dat het mogelijk is om zeewier te verrijken door het twee weken voor de oogst onder verhoogde nitraatconcentraties te laten groeien.

This report is the final report for the FPGA accelerated PID controller, part of the Distributed Control Systems project. This project runs within the Lectoraat Robotics and High Tech Mechatronics of Fontys Hogeschool Engineering Eindhoven. The Lectoraat has the goal to develop applicable knowledge to support education and industry. This knowledge is acquired with projects run in conjunction with the industry. The report will go into detail for the software designed for this project, not the hardware design. This report is intended for follow up students working on the Distributed Control Systems project. Within this report the assumption is made that the reader is at least familiar with the terms EtherCAT, FPGA, Linux and PID controllers. However for each part a small basic introduction is included. For readers looking for the accomplishments in this project, the results are in chapter six. Following are short descriptions of the chapters in this report. The first chapter will give a short introduction to the project. It talks about why the project was conceived, where the project was done and what the expected end result is. The second chapter, the problem definition, talks about how the project has been defined, what is included and what is not and how the customer expects the final product to function and look like. The third chapter details the methodology used during this project. All the research preformed for this project will be described in the forth chapter. This chapter goes into the research into the Xilinx Zynq 7000 chip, Beckhoff's EtherCAT system, how the Serial Peripheral Interface works and how a PID controller functions. Following in chapter five the design is expanded upon. First the toolchain for building for the Zynq chip is explained. This is followed by and explanation of the different software parts that have been designed. Finally chapters six and seven provide the results and the conclusions and recommendations for this project.

Deze afscheidsrede van Frank de Jong verwondert zich over de sterke impact van (directe) instructie in het onderwijs en de daarmee samenhangende gerichtheid op het individuele leren. Om een antwoord te vinden op die verwondering put de rede uit de filosofe Hannah Arendt en haar analyse van de menselijke conditie, de vita activa. Arendt onderscheidt drie menselijke activiteiten: arbeid, werken, spreken en handelen. Arbeid gaat over het voorzien in basisbehoeften en het creëren van een ‘thuis’ met anderen waar het goed toeven is. Werken heeft te maken met het creëren van talen en cultuur en daarmee een kunstmatige wereld. Spreken en handelen omvatten het organiseren van de samenleving en politiek bedrijven. Door het leren en onderwijs te koppelen aan de vita activa komt een beeld naar voren van een onderwijs dat zich voornamelijk richt op arbeid en werken, met een sterke nadruk op (directe) instructie en het aanleren van vaardigheden en kennis. Het spreken en handelen, het ontwikkelen van ideeën en het samenwerken aan een betere wereld, blijven vaak onderbelicht in het onderwijs. Directe instructie mag dan wel efficiënt zijn in het steeds meer geïndustrialiseerde onderwijs met eindtermen en managerial KPI’s, het is niet effectief in het licht van het de totale ontwikkeling als mens. Dit pleit voor meer ruimte te creëren voor idee-ontwikkeling, co-creatie, kennisopbouw en dialoog in het onderwijs. Een onderwijstransitie van een 'belief mode' van leren naar een 'design mode' van leren met de nodige infrastructurele verandering op verschillende niveaus die zo’n transitie vereist. Er is een groeiend bewustwording nodig dat de huidige rol en wijze van leren in het onderwijs en in (school)organisaties onvoldoende bijdraagt aan de oplossingen van de huidige complexe uitdagingen in onze samenleving. Een bredere en diepere benadering van leren in het onderwijs, waarbij niet alleen kennisoverdracht en vaardigheden worden benadrukt, maar ook het ontwikkelen van ideeën, samenwerking en dialoog centraal staan is noodzakelijk, zodat er ruimte is om spreken en handelen te ontwikkelen opdat mensen af en toe uit de rij te stappen om een beter ‘thuis’ te realiseren. Dit doe je niet in je eentje maar in cocreatie met anderen samen en dat moet je (stimu)leren.

This study evaluates the effectiveness of the European Union's Corporate Sustainability Reporting Directive (CSRD) in quantitatively measuring the transition of companies to a circular economy. First, using the most recent literature review on circularity metrics, a complete overview of the currently available circularity metrics is developed. Subsequently, it is determined which circularity metrics can be generated with the available quantitative datapoints of CSRD. The metrics that can be generated were analyzed on their ability to cover all circular strategies, to represent different Product-as-a-Service systems and to acknowledge the key role of Critical Raw Materials in a circular economy. The study finds that, with data disclosed under CSRD, metrics can be generated to cover all circular strategies. However, gaps remain in representing pay-per-use and pay-perperformance systems and the use of Critical Raw Materials. Recommendations are to include ‘Product utilization’ and ‘Mass of Critical Raw Materials used’ in the data disclosed under CSRD and to have an independent institution report data to enable benchmarking of performances. Finally, this study concludes with an overview of the metrics which enable to measure circular transitions using data disclosed by CSRD

Learning by creating qualitative representations is a valuable approach to learning. However, modelling is challenging for students, especially in secondary education. Support is needed to make this approach effective. To address this issue, we explore automated support provided to students while they create their qualitative representation. This support is generated form a reference model that functions as a norm. However, the construction of a reference models is still a challenge. In this paper, we present the reference model that we have created to support students in learning about the melatonin regulation in the context of the biological clock.

Technology in general, and assistive technology in particular, is considered to be a promising opportunity to address the challenges of an aging population. Nevertheless, in health care, technology is not as widely used as could be expected. In this chapter, an overview is given of theories and models that help to understand this phenomenon. First, the design of (assistive) technologies will be addressed and the importance of human-centered design in the development of new assistive devices will be discussed. Also theories and models are addressed about technology acceptance in general. Specific attention will be given to technology acceptance in healthcare professionals, and the implementation of technology within healthcare organizations. The chapter will be based on the state of the art of scientific literature and will be illustrated with examples from our research in daily practice considering the different perspectives of involved stakeholders.

Objectives: Decline in the performance of instrumental activities of daily living (IADL) and mobility may be preceded by symptoms the patient experiences, such as fatigue. The aim of this study is to investigate whether self-reported non-task-specific fatigue is a long-term risk factor for IADL-limitations and/or mobility performance in older adults after 10 years. Methods: A prospective study from two previously conducted cross-sectional studies with 10-year follow-up was conducted among 285 males and 249 females aged 40–79 years at baseline. Fatigue was measured by asking “Did you feel tired within the past 4 weeks?” (males) and “Do you feel tired?” (females). Self-reported IADLs were assessed at baseline and follow-up. Mobility was assessed by the 6-minute walk test. Gender-specific associations between fatigue and IADL-limitations and mobility were estimated by multivariable logistic and linear regression models. Results: A total of 18.6% of males and 28.1% of females were fatigued. After adjustment, the odds ratio for fatigued versus non-fatigued males affected by IADL-limitations was 3.3 (P=0.023). In females, the association was weaker and not statistically significant, with odds ratio being 1.7 (P=0.154). Fatigued males walked 39.1 m shorter distance than those non-fatigued (P=0.048). For fatigued females, the distance was 17.5 m shorter compared to those non-fatigued (P=0.479). Conclusion: Our data suggest that self-reported fatigue may be a long-term risk factor for IADL-limitations and mobility performance in middle-aged and elderly males but possibly not in females.
