Rather than focusing on low-level hardware design, the material emphasises system integration, runtime configuration, and the interaction between software and reconfigurable logic within a modern heterogeneous embedded system. Using a pre-integrated smart camera application as a guiding example, the paper demonstrates how FPGA-based acceleration can be accessed through standard Linux tools, containerised execution environments, and network-based video streaming. The approach is specifically designed for higher education, enabling students to gain practical insight into adaptive computing platforms while maintaining a clear conceptual understanding of hardware-software co-design principles.}, language = {en} } @article{BergmannHaddadThoelkeJeongetal.2026, author = {Bergmann, Marie and Haddad-Thoelke, Pascale and Jeong, Haeran and Kappeler, Ron and Altug, Hicran and Oberwinster, Lukas and Boogaard, Hanna and Pohl, Tobias and Soppa, Vanessa and Ogurtsova, Katherine and Joss, Meltem Kutlar and Andersen, Zorana Jovanovic and Hoffmann, Barbara}, title = {Systematic review and meta-analysis on the health effects of long-term exposure to ultrafine particles}, series = {European Respiratory Review}, volume = {35}, journal = {European Respiratory Review}, number = {179}, publisher = {European Respiratory Society}, issn = {1600-0617}, doi = {10.1183/16000617.0156-2025}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-60272}, pages = {39}, year = {2026}, abstract = {Background Ultrafine particles (≤100 nm diameter) may have a higher toxicity than larger particles but are still not regulated nor part of routine air pollution monitoring. So far, health effects of long-term exposure to ambient ultrafine particles are not well understood, owing to a lack of exposure data and epidemiological studies. Methods We conducted a systematic review and meta-analysis on the health effects of long-term exposure to ultrafine particles, including studies published until December 2024. A meta-analysis was conducted for outcomes with at least four available effect estimates. Confidence in the body of evidence was evaluated using the Office of Health Assessment and Translation method. Results We identified 85 studies investigating various mortality, morbidity and subclinical outcomes. In meta-analyses of single-pollutant models, we found positive associations with natural mortality (hazard ratio 1.06, 95\% CI 1.04-1.08) and C-reactive protein (10.14\% increase (95\% CI -0.51-21.99\%) per 10 000 pt·cm-3 increase in long-term exposure to ultrafine particles, with low and inadequate levels of evidence, respectively. The remaining studies revealed overall limited evidence for adverse effects on a wide range of outcomes. Less than half of the studies adjusted for co-pollutants. Conclusion The evidence base on long-term health effects of ultrafine particles has increased substantially in the past decade, while the overall evidence for independent effects of long-term ultrafine particle exposure remains inadequate to low. More studies are needed to draw firm conclusions about the independent adverse effects of long-term ultrafine particles on various health end-points, with a special focus on the influence of co-pollutant adjustment.}, subject = {Schadstoffbelastung}, language = {en} } @techreport{KostakosKruegerVirchow2025, author = {Kostakos, Georgios and Kr{\"u}ger, Karsten and Virchow, Fabian}, title = {Policy Brief: Education for Responsible Democratic Citizenship.

In view of the challenges democracy is currently facing, at both European and national level, such as growing polarisation, increasing threats to human security and expanding digitalisation, it is important to defend and consolidate it, as a sine-qua-non element of "the European way of life". Education for responsible democratic citizenship (RDC) or education for democracy (EfD) for short is a way of doing so. EfD strategies and tools to strengthen the democratic agency/capacity for action of citizens, the youth in particular, through transformative learning, has been the focus of the DEMOCRAT project (March 2023 to February 2026). This Policy Brief was initially drafted after the seven first months of the DEMOCRAT project but is now being finalised with the experience of two-and-a-half years of project implementation in mind. Key findings and proposed policy actions presented here include: · To safeguard democracy within the European Union, transformative education for democracy must be reinforced, also taking into account fast-moving digitalisation and fast-breached planetary boundaries. · The shift to transformative education for democracy should be based on a coherent competence framework defined in complementarity with the frameworks of citizenship competences proposed by the EU (Key Competences for Lifelong Learning) and the Council of Europe (Competences for Democratic Culture). The four key RDC competences identified by DEMOCRAT are: Solidary Participation, Deliberation, Judgement, and Democratic Resilience. · The above competence framework should be translated by EU member states and schools in different parts of Europe into a sample curriculum for responsible democratic citizenship adjusted to their education systems and societies. · Schools have to be laboratories of democratic practice on a daily basis and across subjects, not just for a few hours of civic education or education for democracy per week, and need to connect with a conducive local, regional, national, European, global and digital environment. · Students need to be aware of both their rights and responsibilities, and be guided to act on both, within their peer groups and in relation to their teachers, parents, local authorities and other relevant stakeholders. A crucial aspect of any approach to education for democracy is the competence of the teacher to create an environment in which the students can learn democracy in action and not just in words}, subject = {Demokratische Bildung}, language = {en} } @techreport{SchmidVirchowWinteretal.2026, author = {Schmid, Andreas and Virchow, Fabian and Winter, Jana and Bittner, Jennifer}, title = {Mediator Training: 3rd German Pilot Intervention Assessment Report}, publisher = {DEMOCRAT}, doi = {10.5281/zenodo.18383656}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:due62-opus-60295}, pages = {13}, year = {2026}, abstract = {The DEMOCRAT Project's work packages are built on each other. This evaluation report is the penultimate stage of the complex Education for democracy (EfD) process designed, tested, evaluated and shared for exploitation by the consortium. DEMOCRAT has outlined a European curriculum for EFD, based on a shared understanding of what democracy means, as well as a competence framework for responsible democratic citizenship (RDC). The curriculum has been piloted in a series of interventions in primary and secondary schools in the six EU member states in which DEMOCRAT has operated: Estonia, Finland, Germany, Ireland, Poland and Spain. In some countries, the testing stage also included interventions in teacher training at higher education institutes. The national activities were designed on the basis of the DEMOCRAT competence framework (included in D2.1), taking into account preliminary national reports on education inequalities and the state of the art in EfD (D3.1) in the six participating countries. The national and local work that is evaluated in the present deliverable is also based on DEMOCRAT deliverable D5.1. (Design of local pilot projects (LPPs)), as well as on subsequently developed tools (see Annexed Guides) and includes the self-assessment of the pilot participants. A final elaboration of the national pilot interventions will be done when they are compiled into the DEMOCRAT Toolbox (D6.1., under preparation). The results of the assessment of the national intervention were presented in the deliverable D5.2 and the results of the comparison of the intervention in the deliverable D5.3). It is worth noting that the various pilots/interventions, because of their limited scale and duration, are not considered as providing strictly scientific evidence about the efficiency and effectiveness of the learning approaches used in terms of RDC competence development. For the DEMOCRAT Project, the primary objective was to test and further develop the competence framework and the assessment tools, as well as to obtain insights of possible success and hindering factors for novel approaches in Education for Democracy. Pilots show that the school heads and teachers have a crucial role in education for democracy and that they can contribute significantly, as agents of research and development, as well as implementation.

Using CuO-H2O nanofluid in a bottom-heated channel with circular expansion, we examine the complex interactions between forced convection, magnetic fields, and uoyancy effects. Through systematic numerical analysis, we explore the combined influences of Rayleigh, Reynolds, and Hartmann numbers on thermal performance. Our findings reveal significant heat transfer enhancement (up to 137 \%) under optimal conditions, particularly with vertical magnetic field orientation at Re = 100 and Ha = 30. The results demonstrate how adiabatic blocks modify flow structures, with larger blocks diminishing vortex intensity while elevated Ra generates secondary vortices that interact with primary circulations. Magnetic field effects show notable dependence on orientation, with vertical fields generally promoting better heat transfer than horizontal configurations. To complement the numerical analysis, we develop a predictive model using Artificial Neural Network (ANN) for Nusselt numbers across various operating conditions, achieving over 99 \% accuracy.

This is important, since the increasing miniaturization and performance demands for electronic devices have led in a growing need for advanced thermal management systems capable of handling rapid transient loads. The novelty of the work lies in examining different heat sink layouts that optimize the heat dissipation capabilities of GR42 PCMs while minimizing size and weight for electronic cooling. The experimental testing was conducted using three configurations, namely no fin, circular fin and hexagonal fin, with three input powers (4 W, 8 W, and 12 W). The experimental results show that the hexagonal-fin heat sink, surface area is 25 \% more than circular fins, exhibited superior thermal performance without significant variation in input power. Notably, the hexagonal-fin heat sink achieved the desired set point temperature of 55 ◦C in 33 \% less time than the circular-fin design and 45 \% less time than the heat sink without fins. Furthermore, the peak temperatures increased up to 21 \% for circular fins. During the charging cycles, the enhancement ratios vary from 72 \% and begin to narrow to 25 \% during discharge cycles. The hexagonal-fin configuration also exhibited superior melting dynamics, completing the phase transition 44 \% faster at higher input power than the circular fins, and established a thermal deviation of nearly 51 \% less than finless heat sinks. These findings underscore the critical role of fin geometry and PCM integration in achieving uniform temperature distribution and improved energy storage efficiency. Overall, the hexagonal-fin heat sink with GR42 PCM shows strong potential as a passive cooling solution for low-power portable electronic devices.}, language = {en} }
