Due to the digitalization, interconnection, and constantly increasing complexity of manufacturing systems in the context of Industrie 4.0, the manual effort necessary to achieve the required safety and security is becoming ever greater and almost impossible to manage, especially for small and medium-sized enterprises. Therefore, this paper examines the existing challenges in this area in more detail and gives an outlook on the possible solutions to ensure safety and security much quicker and with less manual effort.

Thus, we simulated the metalimnetic oxygen minimum (MOM) in the Rappbode Reservoir with a well-established two-dimensional water quality model (CE-QUAL-W2) to systematically quantify the chain of events leading to its formation. We used high-resolution measured data to calibrate the model, which accurately reproduced the physical (e.g. water level and water temperature), biogeochemical (e.g. nutrient and oxygen dynamics) and ecological (e.g. algal community dynamics) features of the reservoir, particularly the spatial and temporal extent of the MOM. The results indicated that around 60% of the total oxygen consumption rate in the MOM layer originated from benthic processes whereas the remainder originated from pelagic processes. The occurrence of the cyanobacterium Planktothrix rubescens in the metalimnion delayed and slightly weakened the MOM through photosynthesis, although its decaying biomass ultimately induced the MOM. Our research also confirmed the decisive role of water temperature in the formation of the MOM since the water temperatures, and thus benthic and pelagic oxygen consumption rates, were higher in the metalimnion than in the hypolimnion. Our model is not only providing novel conclusions about the drivers of MOM development and their quantitative contributions, it is also a new tool for understanding and predicting ecological and biogeochemical water quality dynamics.","lang":"eng"}],"quality_controlled":"1","publisher":"Elsevier BV","date_created":"2024-12-08T20:26:00Z","publication":"Water research : a journal of the International Water Association","publication_identifier":{"issn":["0043-1354"],"eissn":["1879-2448"]},"date_updated":"2024-12-09T10:25:49Z","language":[{"iso":"eng"}],"keyword":["Rappbode reservoir","CE-QUAL-W2","Planktothrix rubescens","Metalimnion","Oxygen consumption","Benthic processes"],"extern":"1","title":"The formation of a metalimnetic oxygen minimum exemplifies how ecosystem dynamics shape biogeochemical processes: A modelling study","volume":175,"citation":{"chicago":"Mi, Chenxi, Tom Shatwell, Jun Ma, Valerie Carolin Wentzky, Bertram Boehrer, Yaqian Xu, and Karsten Rinke. “The Formation of a Metalimnetic Oxygen Minimum Exemplifies How Ecosystem Dynamics Shape Biogeochemical Processes: A Modelling Study.” <i>Water Research : A Journal of the International Water Association</i> 175, no. 5 (2020). <a href=\"https://doi.org/10.1016/j.watres.2020.115701\">https://doi.org/10.1016/j.watres.2020.115701</a>.","apa":"Mi, C., Shatwell, T., Ma, J., Wentzky, V.

Although a multitude of solutions has been applied to this modern Industry 4.0 problem, it remains an open research issue to identify the key characteristics subjacent to an anomaly, sc. generate hypothesis as to why they appear. In recent years, machine learning models have been regarded as universal solution for a wide range of problems. While most of them suffer from non-self-explanatory representations, Gaussian Processes (GPs) deliver interpretable and robust statistical data models, which are able to cope with unreliable, noisy, or partially missing data. Thus, we regard them as a suitable solution for detecting and appropriately representing anomalies and their respective characteristics. In this position paper, we discuss the problem of automatic and interpretable anomaly detection by means of GPs. That is, we elaborate on why GPs are well suited for anomaly detection and what the current challenges are when applying these probabilistic models to large-scale production data."}],"publication_status":"published"},{"publisher":"Technische Hochschule Ostwestfalen-Lippe","status":"public","conference":{"start_date":"2018-10-04","end_date":"2018-10-05","name":"8th International Conference","location":"Lemgo"},"department":[{"_id":"DEP1306"},{"_id":"DEP7037"}],"main_file_link":[{"open_access":"1","url":"https://www.hs-owl.de/fileadmin/diman/Veroeffentlichungen/PEM2018_proceedings_web.pdf"}],"author":[{"id":"71733","full_name":"Springer, André","first_name":"André","last_name":"Springer"},{"full_name":"Nothdurft, Sarah","last_name":"Nothdurft","first_name":"Sarah"},{"full_name":"Lahdo, Rabi","last_name":"Lahdo","first_name":"Rabi"},{"full_name":"Seffer, Oliver","last_name":"Seffer","first_name":"Oliver"}],"year":2018,"publication_status":"published","citation":{"chicago-de":"Springer, André, Sarah Nothdurft, Rabi Lahdo und Oliver Seffer. 2018. <i>Dissimilar Metal Joints - Laser Based Manufacturing Processes for Components of Tomorrow</i>. <i>8th International Conference on Production Engineering and Management</i>.

This support aims to both support workers to better execute their tasks and to reduce the effort and time required when working. However, due to the large spectrum of assistance systems, it is hard to acquire an overview and to select an adequate system for a smart factory based on meaningful criteria.

It will be of particular interest for a CR system to apply predictive modeling in order to forecast the behavior of the coexisting environment. A secondary cognitive user shall use preemptive tuning of its operating parameters following the predictive model. However, a considerable challenge is to generate an accurate model and predict efficiently in order to meet strict time related requirements of industrial applications. Such predictive modeling has already gained some attention but real-time experimental results have never been reported to the best of our knowledge. In this contribution we investigate the performance of a Markov model based CR system using simulative and experimental environments for its application in industrial systems.","lang":"eng"}],"department":[{"_id":"DEP5000"},{"_id":"DEP5023"}],"conference":{"location":"Krakow, Poland ","name":"17th IEEE Conference on Emerging Technologies and Factory Automation","start_date":"2012-09-17","end_date":"2012-09-21"},"publisher":"IEEE","publication_status":"published","doi":"10.1109/ETFA.2012.6489557","_id":"10164","place":"Piscataway, NJ","type":"conference_editor_article","user_id":"83781"}]
