This paper fills this gap and translates the regulatory requirements from the context of German railways for the AI developer community. As a result, tasks such as train’s path monitoring for collision prediction, signal detection, door operation, etc. are identified. Based on this analysis, a functionally justified sensor setup with detailed configuration requirements is presented. This setup was also evaluated by a survey within the railway industry. The evaluated sensors include RGB/IR cameras, LIDARs, radars and ultrasonic sensors. Calculations and estimates for the evaluated sensors are presented graphically and included in this paper. However, the ultimate sensor setup is still a subject of research. The results of this paper also address the lack of training and test datasets for railway AI systems. It is proposed to acquire research datasets that will allow the training of domain adaptation algorithms to transform other datasets, thus increasing the number of available datasets.

Ventilation dilutes contaminants such as bioeffluents generated by occupants, substances emitted from building materials, and the water vapor generated by occupants’ activities. In a building that requires heating and cooling, adequate ventilation is crucial to minimize energy consumption while maintaining healthy indoor air quality. However, measuring the actual magnitude of the natural ventilation rate, including infiltration through the building envelope and airflow through the building openings, is not always feasible. Although international and national standards suggested the required ventilation rates to maintain acceptable indoor air quality in buildings, they did not offer action plans to achieve or evaluate those design ventilation rates in buildings in use. In this study, the occupant-generated carbon dioxide (CO2) tracer gas decay method was applied to estimate the ventilation rates in an office room in Seoul, South Korea, from summer to winter. Using the method, real-time ventilation rates can be calculated by monitoring indoor and outdoor CO2 concentrations without injecting a tracer gas. For natural ventilation in the test room, 145 mm-diameter circular openings on the fixed glass were used. As a result, first, the indoor CO2 concentrations were used as an indicator to evaluate how much the indoor air quality deteriorated when all the windows were closed in an occupied office room compared to the international standards for indoor air quality. Moreover, we found out that the estimated ventilation rates varied depending on various environmental conditions, even with the same openings for natural ventilation. Considering the indoor and outdoor temperature differences and outdoor wind speeds as the main factors influencing the ventilation rates, we analyzed how they affected the ventilation rates in the different seasons of South Korea. When the wind speeds were calm, less than 2 m/s, the temperature difference played as a factor that influenced the estimated ventilation rates. On the other hand, when the temperature differences were low, less than 3 °C, the wind speed was the primary factor. This study raises awareness about the risk of poor indoor air quality in office rooms that could lead to health problems or unpleasant working environments. This study presents an example of estimating the ventilation rates in an existing building. By using the presented method, the ventilation rate in an existing building can be simply estimated while using the building as usual, and appropriate ventilation strategies for the building can be determined to maintain the desired indoor air quality."}],"place":"Basel","status":"public","author":[{"first_name":"Hyeonji","full_name":"Seol, Hyeonji","id":"77436","last_name":"Seol"},{"full_name":"Arztmann, Daniel","id":"58805","last_name":"Arztmann","first_name":"Daniel"},{"first_name":"Naree","full_name":"Kim, Naree","last_name":"Kim"},{"full_name":"Balderrama, Alvaro","id":"79418","last_name":"Balderrama","first_name":"Alvaro"}],"publication":"Sustainability","title":"Estimation of Natural Ventilation Rates in an Office Room with 145 mm-Diameter Circular Openings Using the Occupant-Generated Tracer-Gas Method","department":[{"_id":"DEP1600"},{"_id":"DEP1634"}],"publication_status":"published","publication_identifier":{"issn":["2071-1050"]},"issue":"13","doi":"10.3390/su15139892","keyword":["Management","Monitoring","Policy and Law","Renewable Energy","Sustainability and the Environment","Geography","Planning and Development","Building and Construction"],"citation":{"ieee":"H.

Its application is demonstrated in a simulation case study for a relevant industrial task in process development, the design of a robust cell culture expansion process (seed train), meaning that despite uncertainties and variabilities concerning cell growth, low variations of viable cell density during the seed train are obtained. Compared to a non-optimized reference seed train, the optimized process showed much lower deviation rates regarding viable cell densities (&lt;10% instead of 41.7%) using five or four shake flask scales and seed train duration could be reduced by 56 h from 576 h to 520 h. Overall, it is shown that applying Bayes optimization allows for optimization of a multi-objective optimization function with several optimizable input variables and under a considerable amount of constraints with a low computational effort. This approach provides the potential to be used in the form of a decision tool, e.g., for the choice of an optimal and robust seed train design or for further optimization tasks within process development.","lang":"eng"}],"place":"Basel","status":"public","author":[{"first_name":"Tanja","last_name":"Hernández Rodriguez","id":"52466","full_name":"Hernández Rodriguez, Tanja"},{"full_name":"Sekulic, Anton","last_name":"Sekulic","first_name":"Anton"},{"first_name":"Markus","last_name":"Lange-Hegermann","id":"71761","full_name":"Lange-Hegermann, Markus"},{"first_name":"Björn","full_name":"Frahm, Björn","id":"45666","last_name":"Frahm"}]},{"year":"2022","date_updated":"2024-08-12T08:07:32Z","user_id":"83781","date_created":"2022-04-14T10:58:17Z","main_file_link":[{"open_access":"1","url":"https://conference.pixel-online.net/NPSE/files/npse/ed0011/FP/6790-CDEV5427-FP-NPSE11.pdf"}],"language":[{"iso":"eng"}],"place":"Bologna","status":"public","author":[{"first_name":"Thomas","last_name":"Bröker","full_name":"Bröker, Thomas"},{"first_name":"Nina","last_name":"Schmulius","full_name":"Schmulius, Nina","id":"81110"},{"last_name":"Schmohl","id":"71782","full_name":"Schmohl, Tobias","orcid":"https://orcid.org/0000-0002-7043-5582","first_name":"Tobias"},{"first_name":"Fabian","full_name":"Dulisch, Fabian","last_name":"Dulisch"},{"first_name":"Sabrina","last_name":"Marquardt","full_name":"Marquardt, Sabrina","id":"81111"},{"first_name":"Max","last_name":"Höllen","full_name":"Höllen, Max"},{"full_name":"Voit, Thomas","last_name":"Voit","first_name":"Thomas"},{"last_name":"Zinger","full_name":"Zinger, Benjamin","first_name":"Benjamin"}],"volume":11,"type":"conference_editor_article","_id":"7578","page":"22-26","abstract":[{"lang":"eng","text":"In recent years considerable research efforts have been made to provide evidence for a nexus be-tween game design elements in non-game contexts. Our research presents a new approach to bridge game design elements and educational theory: defining a set of motivational “patterns” used for peda-gogical purposes in university teaching scenarios. To this end, we will build upon preliminary empirical results from a research project called EMPAMOS®. It derived a set of motivational elements frequently used in social game designs. Our hypothesis is that these elements resemble on a structural level and are directly transferable to motivational factors in online education contexts. \r\nFocused on cooperative teaching and learning, we develop a curriculum to enable educators to im-plement motivational molecules from game design in their learning settings. The paper presents basic premises and a preliminary structure of the curriculum. By examining educational settings in terms of a “broken game”, we provide a new perspective on the prerequisites for learning at the university level."}],"keyword":["cooperative learning","gamification","motivation","train-the-trainer","curriculum"],"conference":{"name":"11th International Conference New Perspectives in Science Education","end_date":"2022-03-18","location":"Florenz","start_date":"2022-03-17"},"publication":"New Perspectives in Science Education","department":[{"_id":"DEP2000"},{"_id":"DEP1200"}],"title":"What Can Educators Learn from Social Game Design in University Online Teaching?","publication_status":"published","intvolume":"        11","series_title":"New Perspectives in Science Education","publisher":"Libreriauniversitaria.it","quality_controlled":"1","citation":{"van":"Bröker T, Schmulius N, Schmohl T, Dulisch F, Marquardt S, Höllen M, et al.

The phenotype of the cells in a reactor plays an important role. Are clonal cell populations showing high cell-specific growth rates more favorable than cell lines with higher cell-specific productivities or vice versa? Five clonal Chinese hamster ovary cell populations were analyzed based on the data of a 3-month-stability study. We adapted a mechanistic cell culture model to the experimental data of one such clonally derived cell population.

We showed thus unequivocally that growth rates have a higher impact (up to three times) on overall process productivity and for product output per year, whereas cells with higher productivity can potentially generate higher product concentrations in the production vessel.","lang":"eng"}],"volume":9,"_id":"11376","type":"scientific_journal_article"},{"place":"New York, NY","status":"public","author":[{"last_name":"Schäfers","id":"77945","full_name":"Schäfers, Tobias","orcid":"0000-0002-2533-335X","first_name":"Tobias"},{"first_name":"Gopalakrishnan","full_name":"Narayanamurthy, Gopalakrishnan","last_name":"Narayanamurthy"},{"last_name":"Moser","full_name":"Moser, Roger","first_name":"Roger"},{"full_name":"Leban, Marina","last_name":"Leban","first_name":"Marina"}],"volume":38,"_id":"7518","page":"2073-2088","type":"scientific_journal_article","abstract":[{"lang":"eng","text":"The sharing economy provides short-term access to products without the risks associated with ownership. While extant research primarily examined it in the context of affluent consumer segments, the sharing economy may offer opportunities for consumers at the base of the economic pyramid, where ownership risks prevent access to products that could create societal benefits. Drawing from risk perception theory, we examine how access-based services, as an alternative to ownership, can mitigate perceived risk dimensions. An experimental study reveals that, in contrast to consumers with higher income, low-income consumers perceive access-based services to entail less financial risk, resulting in a greater inclination to access a good than to own it. In a second study, we explore these differences by comparing access with a risk mitigation strategy. We find that at the base of the pyramid, access is perceived to entail less financial risk than both ownership and ownership with a warranty. The results indicate the importance of the sharing economy for addressing the limited availability of resources for alleviating poverty. Based on our findings, we derive implications for consumers and service providers at the base of the pyramid, and discuss how the COVID-19 pandemic may be detrimental to the identified opportunities."}],"date_updated":"2025-06-26T13:23:58Z","year":"2021","user_id":"83781","external_id":{"isi":["000672550800001"]},"date_created":"2022-04-13T10:45:02Z","language":[{"iso":"eng"}],"intvolume":"        38","publisher":"Wiley","quality_controlled":"1","citation":{"apa":"Schäfers, T., Narayanamurthy, G., Moser, R., &#38; Leban, M.

The project proposes a mixed-use transformation that reinterprets the building as a “city within the city,” inspired by Le Corbusier’s Unité d’Habitation in Marseille. The existing structure is strategically reduced to its essential load-bearing concrete frame and floor slabs, preserving the structural skeleton while enabling radical spatial reconfiguration.\r\nPrefabricated timber modules are inserted and cantilevered between the reinforced-concrete columns, extending the usable floor area and introducing a warm, contemporary material contrast to the original façade. This intervention not only increases density and flexibility but also redefines the tower’s appearance, giving it a cosmopolitan and forward-looking architectural identity. The ground floor is conceived as an open and publicly accessible urban platform, activating the surrounding plaza and strengthening social interaction. Upper floors are redesigned as affordable and attractive living spaces for young residents, encouraging a diverse and vibrant community within the building.\r\nA newly designed park-like rooftop landscape provides recreational space and panoramic views over the city, enhancing environmental quality and urban connectivity. By combining structural preservation, modular timber construction, public programming, and residential reuse, the proposal demonstrates how high-rise retrofitting can generate social, ecological, and economic value simultaneously. The project positions adaptive reuse as a viable strategy for sustainable urban regeneration and architectural longevity.","lang":"eng"}],"citation":{"havard":"L.

This seed train is time- and cost-intensive but offers potential for optimization. A method and a protocol are described for the seed train mapping, directed modeling without major effort, and its optimization regarding selected optimization criteria such as optimal points in time for cell passaging.
