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. The sensor setup is also recommended for such research datasets.","lang":"eng"}],"user_id":"83781","intvolume":"         3","type":"scientific_journal_article","place":"[Cham] ","_id":"13020","article_number":"22","doi":"10.1007/s44163-023-00066-4"},{"publication_status":"published","publisher":"MDPI AG","abstract":[{"text":"<jats:p>consuming and often performed rather empirically. Efficient optimization of multiple objectives such as process time, viable cell density, number of operating steps &amp; cultivation scales, required medium, amount of product as well as product quality depicts a promising approach. This contribution presents a workflow which couples uncertainty-based upstream simulation and Bayes optimization using Gaussian processes. 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"}],"issue":"5","department":[{"_id":"DEP4000"}],"intvolume":"        10","user_id":"83781","type":"scientific_journal_article","doi":"10.3390/pr10050883","article_number":"883","_id":"11377","place":"Basel","citation":{"ufg":"<b>Hernández Rodriguez, Tanja u. a.</b>: Designing Robust Biotechnological Processes Regarding Variabilities Using Multi-Objective Optimization Applied to a Biopharmaceutical Seed Train Design, in: <i>Processes</i> 10 (2022), H. 5.","mla":"Hernández Rodriguez, Tanja, et al. “Designing Robust Biotechnological Processes Regarding Variabilities Using Multi-Objective Optimization Applied to a Biopharmaceutical Seed Train Design.” <i>Processes</i>, vol. 10, no. 5, 883, 2022, <a href=\"https://doi.org/10.3390/pr10050883\">https://doi.org/10.3390/pr10050883</a>.","havard":"T.

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.","lang":"eng"}],"publication_status":"published","series_title":"New Perspectives in Science Education"},{"keyword":["Gaussian processes","Bayes optimization","Pareto optimization","multi-objective","cell culture","seed train"],"place":"Basel","language":[{"iso":"eng"}],"_id":"10193","doi":"https://doi.org/10.3390/pr10050883","user_id":"83781","date_updated":"2023-08-16T09:24:16Z","editor":[{"full_name":"Pörtner, Ralf","last_name":"Pörtner","first_name":"Ralf"},{"full_name":"Möller, Johannes","first_name":"Johannes","last_name":"Möller"}],"publication":"Bioprocess Systems Engineering Applications in Pharmaceutical Manufacturing","publication_identifier":{"eisbn":["978-3-0365-5209-5"],"isbn":["978-3-0365-5210-1"],"eissn":["2227-9717"]},"type":"book_chapter","date_created":"2023-08-08T12:58:36Z","status":"public","page":"21-48","publisher":"MDPI","quality_controlled":"1","year":"2022","author":[{"full_name":"Hernández Rodriguez, Tanja","first_name":"Tanja","id":"52466","last_name":"Hernández Rodriguez"},{"first_name":"Anton","full_name":"Sekulic, Anton","last_name":"Sekulic"},{"full_name":"Lange-Hegermann, Markus","last_name":"Lange-Hegermann","id":"71761","first_name":"Markus"},{"first_name":"Björn","last_name":"Frahm","id":"45666","full_name":"Frahm, Björn"}],"department":[{"_id":"DEP4000"}],"abstract":[{"text":"Development and optimization of biopharmaceutical production processes with cell cultures is cost- and time-consuming and often performed rather empirically. Efficient optimization of multiple objectives such as process time, viable cell density, number of operating steps & cultivation scales, required medium, amount of product as well as product quality depicts a promising approach. This contribution presents a workflow which couples uncertainty-based upstream simulation and Bayes optimization using Gaussian processes. 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 (<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"}],"volume":"special issue","citation":{"short":"T.

One of these steps is the time- and cost-intensive cell proliferation process (also called seed train) to increase cell number from cell thawing up to production scale. Challenges like complex cell metabolism, batch-to-batch variation, variabilities in cell behavior, and influences of changes in cultivation conditions necessitate adequate digital solutions to provide information about the current and near future process state to derive correct process decisions.\r\nFor this purpose digital seed train twins have proved to be efficient, which digitally display the time-dependent behavior of important process variables based on mathematical models, strategies, and adaption procedures.\r\nThis chapter will outline the needs for digitalization of seed trains, the construction of a digital seed train twin, the role of parameter estimation, and different statistical methods within this context, which are applicable to several problems in the field of bioprocessing. The results of a case study are presented to illustrate a Bayesian approach for parameter estimation and prediction of an industrial cell culture seed train for seed train digitalization.","lang":"eng"}],"publisher":"Springer","quality_controlled":"1","series_title":"Advances in Biochemical Engineering/Biotechnology","publication_status":"published","place":"Berlin, Heidelberg","_id":"3349","doi":"https://doi.org/10.1007/10_2020_137","type":"book_chapter","user_id":"83781","intvolume":"       176"},{"keyword":["Seed train Optimization Modeling Prediction Space-Time-Yield (STY) Systems approach Bioinformatics Computational biotechnology Suspension Production"],"language":[{"iso":"eng"}],"date_updated":"2023-03-15T13:49:39Z","publication_identifier":{"isbn":["9781627037327"],"issn":["1064-3745","1940-6029"],"eisbn":["9781627037334"]},"publication":"Animal Cell Biotechnology","date_created":"2020-05-19T14:45:43Z","status":"public","page":"355-367","year":2013,"author":[{"full_name":"Frahm, Björn","last_name":"Frahm","first_name":"Björn"}],"citation":{"ieee":"B.
