Long-Term Monitoring of Mechanical Ventilation and Window Airing in Classrooms: A Controlled Observational Study
No full textIndoor environmental quality is essential for pupils` health, comfort, and academic performance. However, recent studies indicate that indoor air quality (IAQ) in classrooms is often inadequate. This observational study examines the impact of three ventilation concepts on IAQ and thermal comfort under real-life school conditions: manual window airing combined with CO2 traffic lights, decentralized mechanical ventilation, and centralized mechanical ventilation. Eight classrooms in three elementary schools were monitored from 10/2023 to 04/2024. Continuous long-term measurements covered CO2, PM2.5, VOCs, indoor air temperature, relative humidity and window opening states in the classrooms, and ambient data including PM2.5 at each school. Significant differences were found in all five indoor parameters across the three ventilation concepts. The decentralized ventilation group achieved the lowest CO2 concentrations (18–22% lower), while the window airing group showed the highest PM2.5 levels (mean of 6 µg/m3) and the lowest temperatures (21% of the time below 20 °C). Relative humidity tended to be too low for all concepts, particu-larly with mechanical ventilation (medians below 40%). Windows in the window airing group were opened approximately twice as long. The findings highlight the benefits of well-operated mechanical ventilation systems and underscore the importance of user awareness and system management

No full textThis paper presents a new approach for providing contextual information in real-world environments. Our approach is consciously designed to be low-threshold; by using mirrors as augmented reality surfaces, no devices such as AR glasses or smartphones have to be worn or held by the user. It enables technical and non-technical objects in the environment to be visually highlighted and thus subtly draw the attention of people passing by. The presented technology enables the provision of information that can be viewed in more detail by the user if required by slowing down their movement. Users can decide whether this is relevant to them or not. A prototype system was implemented and evaluated through a user study. The results show a high level of acceptance and intuitive usability of the system, with participants being able to reliably perceive and process the information displayed. The technology thus offers promising potential for the unobtrusive and context-sensitive provision of information in various application areas. The paper discusses limitations of the system and outlines future research directions to further optimize the technology and extend its applicability
Optical design and tolerance analysis of additively manufactured optical interfaces for spin qubits
No full textReadout efficiency is crucial in all optical quantum technologies that employ single qubits or single quantum emitters. One of those systems is the nitrogen vacancy (NV-Center) in diamond, where total internal reflection at the diamond surface severely limits the photon yield. Recent efforts for enhancing the collection efficiency of single NV-Centers include shaping the diamond surface to a hemisphere or printing solidimmersion lenses (SIL) on top of it. In order to further improve the photon collection efficiency, we intend to additively manufacture polymer lenses on top of the crystal via multi-photon lithography. This works presents multiple optical designs based on 3D-printed polymer lenses and discusses their performance, robustness and scalability via simulation of their optical, thermal and mechanical properties.
