Therefore, it is necessary to investigate and quantify the chemical, physical and sensory effects of this treatment. In this study, cloudy apple juice was treated at different time-temperature combinations with equivalent microbial lethality with 161.6 PU. These can be categorized as low temperature/long time (LTLT with 70°C and 80°C) or high temperature/short time (HTST with 90°C, 100°C and 105°C) treatments. The results were compared to those of untreated juice. HTST treatment had significantly less impact on the juice compared to LTLT treatment. LTLT-treated juices were characterized by different sensory attributes, such as raisin and caramel odor and bitter taste. In contrast, the untreated and HTST-treated juices exhibited odors like pear and lemon. There were also significant differences in turbidity, sugar composition, viscosity and a heightened 5-(hydroxymethyl)furfural (HMF) content with LTLT treatment. In summary, HTST-treated juices are more similar to the untreated juices and are rated higher in terms of quality characteristics. The lowest pasteurization temperature of 70°C results in the greatest deterioration of juice quality. It can be concluded that different pasteurization conditions showed different effects on juice quality, despite having the same microbiological lethality of 161.6 PU. Results can be considered when designing pasteurization processes."}],"keyword":["Cloudy apple juice","HTST","juice pasteurization","sensory analysis","process optimization","equivalent microbial lethality"]},{"publication":"Proceedings of the 70th IEEE Holm Conference on Electrical Contacts (HLM)","series_title":"Electrical contacts","_id":"13433","publication_status":"published","date_created":"2026-02-24T14:48:06Z","language":[{"iso":"eng"}],"citation":{"havard":"M.

However, increasing performance requirements (e.g., operation at elevated temperatures) and regulatory restrictions are prompting a reassessment of lubricant selection. In this study, the influence of three lubricants (one oil and two greases), operating temperature (room temperature and 130°C), and applied volume (low, medium and high volume) on electrical contact resistance (ECR) and coefficient of friction (CoF) is investigated by means of fretting wear tests on silver-plated contacts. The results show that unlubricated silver contacts exhibit a longer stable phase at 130 °C than at room temperature. For lubricated contacts, service life is influenced by both temperature and lubricant volume. Certain lubricants demonstrate earlier fail at room temperature than at elevated temperatures. The findings highlight the importance of careful selection and optimization of lubricants for electrical connectors under varying environmental conditions."}],"keyword":["Connectors","Resistance","Silver","Lubricants","Contacts","Oils","Friction","Corrosion","Optimization"],"publisher":"IEEE","type":"conference_editor_article","doi":"10.1109/hlm51652.2025.11278329","date_updated":"2026-02-27T11:06:57Z"},{"date_updated":"2024-02-01T12:56:04Z","file_date_updated":"2024-02-01T12:50:55Z","defense_date":"2024-01-29","publisher":"Technischen Hochschule Ostwestfahlen-Lippe","type":"bachelor_thesis","abstract":[{"text":"This thesis examines the impacts of scene and rendering optimizations techniques aimed for GPU rendering within the realm of animated scene for offline rendering.

Quantitative approaches and Artificial Intelligence (AI) applications offer the potential to improve work design. However, current research does not entirely focus on human-centric criteria that enable time autonomy. This paper addresses this gap by developing a set of criteria to evaluate intelligent personnel planning approaches based on their ability to enhance time autonomy for employees. Existing quantitative approaches are not sufficient to fully integrate the developed criteria.Consequently, a novel model approach is proposed in an attempt to bridge the gap between current practices and the newly developed criteria. This two-stage planning approach fosters democratization of time autonomy on the shopfloor, moving beyond traditional top-down scheduling. The paper concludes by outlining the implementation process and discusses future developments with respect to AI for this model approach.Practical Relevance: In order to make working conditions on the shopfloor in high-wage countries more attractive, an alternative organization of shift work is needed. Intelligent planning approaches that combine traditional operations research methods with artificial intelligence approaches can democratize shift organization regarding time autonomy. Planning that takes both employee and employer preferences into account in a balanced way will strengthen the long-term competitiveness of manufacturing companies in high-wage countries and counteract the shortage of skilled labor.","lang":"eng"}],"page":"277-298"},{"author":[{"first_name":"Imke","full_name":"Weishaupt, Imke","last_name":"Weishaupt","id":"58425"}],"place":"Berlin","citation":{"chicago-de":"Weishaupt, Imke. 2023.

There are already various approaches to improve this conventionally managed process step in terms of product and resource preservation. Compared to these novel technologies, the use of real-time process analytics offers great potential to improve already existing process plants by implementing inline capable process analytical tools. This allows direct control of the reactions taking place and changes during the running process. Instead of post process, random product control, quality control during the process can be made rendered. The chemical and pharmaceutical industry serves as a reference industry for the use of process analytical tools, although the reactions and product matrices are less complex. In the food industry, on the other hand, there is a greater variation in raw materials and intermediate products. In addition, a large number of reactions can take place in parallel within a process, and the physical states and properties of the individual components can vary. A uniform set of rules for the use of process analytical tools does not exist here. Each product, each process provides its own research potential, so that a large research gap opens up in the area of the food industry.\r\nIn order to contribute to closing this gap, this thesis presents a novel approach to improve the process of pasteurization of liquid food. For fruit juices as an application, near infrared spectroscopy in combination with chemometric methods was applied to make the process more product specific. Based on known weaknesses of the process, the relevant aspects for a product-specific treatment were identified. In the further course, the suitability of near infrared spectroscopy as a process analytical tool in the process of pasteurization was verified. Moreover, it was investigated whether a sufficiently accurate identification of the product type as well as the microbiologically relevant properties can be achieved by the application of chemometric methods. In the course of this, the suitability of the measurement methodology was confirmed and solutions were established for any process influences. The product classification and description of the microbiologically relevant parameters extract content and pH value were also implemented with sufficient accuracy. Knowing the destruction kinetics of relevant microorganisms, the product-specific determination of target values for the necessary lethal heat input could be realized. In addition, an analysis of the actual values was carried out on the basis of a chemometric regression method by inferring the microbiological pasteurization effect through the chemical reaction of acid hydrolytic sucrose degradation by means of the indirect approach. This required knowledge of the chemical reaction kinetics and mahematical modeling of the degradation behavior. The novel approach could be confirmed by calculations using results from off-line analysis, whereas the use of near infrared spectroscopy as an inline method still revealed potential for optimization with respect to measurement accuracies.\r\nIn summary, the results of this work provide a promising opportunity to make conventional processes for the preservation of liquid foods more product-specific by using near-infrared spectroscopy as an inline-capable and multimodal sensor technique, leading to an increase in process efficiency and product quality."},{"lang":"ger","text":"Der Prozess der thermischen Haltbarmachung von flüssigen Lebensmitteln ist ein sicherheitsrelevanter Prozessschritt in der Verarbeitung von Produkten wie Fruchtsäften und ist mit einem hohen energetischen Aufwand und Sicherheitszuschlag verbunden. Um diesen konventionell geführten Prozessschritt hinsichtlich Produkt- und Ressourcenschonung zu optimieren, gibt es bereits verschiedene Ansätze. Im Vergleich zu neuartigen Technologien bietet der Einsatz von Echtzeit-Prozessanalytik großes Potential bereits bestehende Prozessanlagen durch die Implementierung inlinefähiger Prozessanalysetools zu verbessern. Dies ermöglicht eine Kontrolle ablaufender Reaktionen im laufenden Prozess. Anstelle nachgelagerter, stichprobenartiger Produktkontrolle kann eine Qualitätslenkung im Prozess erfolgen. Vorbildindustrie bezüglich des Einsatzes von Prozessanalysetools ist die pharmazeutische Industrie, wo Reaktionen und Produktmatrices allerdings weniger komplex sind. In der Lebensmittelindustrie gibt es eine größere Schwankungsbreite der Rohstoffe und Zwischenprodukte. Zudem können innerhalb eines Prozesses eine Vielzahl an Reaktionen parallel ablaufen und die Zustandsformen und Eigenschaften der einzelnen Komponenten variieren. Ein einheitliches Regelwerk zum Einsatz der Prozessanalysetools existiert nicht. Jedes Produkt, jeder Prozess liefert eigenes Forschungspotential, sodass sich im Bereich der Lebensmittelindustrie eine große Forschungslücke auftut.\r\nUm einen Beitrag zur Schließung dieser Lücke zu leisten, zeigt diese Arbeit einen neuartigen Lösungsansatz auf, um den Prozess der Pasteurisation flüssiger Lebensmittel zu verbessern. Am Anwendungsfall von Fruchtsäften wurde der Einsatz von Nahinfrarotspektroskopie in Kombination mit chemometrischen Methoden genutzt, um den Prozess produktspezifischer zu gestalten. Ausgehend von bekannten Schwachstellen des Prozesses wurden die relevanten Aspekte identifiziert, deren Kenntnis für eine produktspezifische Behandlung relevant sind. Angefangen mit der Überprüfung der Eignung von Nahinfrarotspektroskopie als Prozessanalysetool im Prozess der Pasteurisation, wurde untersucht, ob eine Identifikation des Produkttyps sowie der mikrobiologisch relevanten Eigenschaften durch die Anwendung chemometrischer Methoden erfolgen kann. In diesem Zuge konnte eine Eignung der Messmethodik bestätigt werden und für etwaige Prozesseinflüsse Lösungsansätze etabliert werden. Auch die Produktklassifizierung und Beschreibung der mikrobiologisch relevanten Parameter Extraktgehalt und pH-Wert wurden hinreichend genau umgesetzt. Unter Kenntnis der Abtötungskinetiken entsprechend relevanter Mikroorganismen konnte die produktspezifische Ermittlung für Sollwerte des notwendigen letalen Hitzeeintrags realisiert werden. Im Weiteren wurde eine Analyse der Ist-Werte auf Basis einer chemometrischen Regressionsmethode durchgeführt, indem mittels des indirekten Ansatzes über die chemische Reaktion der säurehydrolytischen Saccharosedegradation auf den mikrobiologischen Pasteurisationseffekt geschlossen wurde. Dazu war die Kenntnis der chemischen Reaktionskinetik notwendig und die mathematische Modellierung des Abbauverhaltens. Der neuartige Ansatz konnte mittels Berechnungen unter Verwendung von Ergebnissen der Offline-Analytik bestätigt werden. Der Einsatz von Nahinfrarotspektroskopie als Inline- Methode hingegen offenbarte Optimierungspotenzial hinsichtlich der Messgenauigkeiten.\r\nZusammenfassend liefern die Ergebnisse dieser Arbeit eine vielversprechende Möglichkeit herkömmliche Prozesse zur Haltbarmachung von flüssigen Lebensmitteln durch den Einsatz von Nahinfrarotspektroskopie als inlinefähige, multimodale Sensortechnik produktspezifischer zu gestalten, was zur Steigerung der Prozesseffizienz und Produktqualität führt."}],"supervisor":[{"last_name":"Rappsilber","full_name":"Rappsilber, Juri ","first_name":"Juri "},{"first_name":"Peter ","full_name":"Neubauer, Peter ","last_name":"Neubauer"},{"orcid":"0000-0001-6401-8873","full_name":"Schneider, Jan","id":"13209","last_name":"Schneider","first_name":"Jan"},{"last_name":"Garbe","full_name":"Garbe, Leif-Alexander ","first_name":"Leif-Alexander "}],"page":"144"},{"editor":[{"first_name":"Jürgen","full_name":"Jasperneite, Jürgen","id":"1899","last_name":"Jasperneite"},{"first_name":"Lukasz","last_name":"Wisniewski","id":"1710","full_name":"Wisniewski, Lukasz"},{"first_name":"Kim","full_name":"Fung Man, Kim","last_name":"Fung Man"}],"publisher":"IEEE","type":"conference_editor_article","date_updated":"2025-06-26T07:48:22Z","doi":"10.1109/INDIN51400.2023.10217913","status":"public","user_id":"83781","year":"2023","corporate_editor":["Institute of Electrical and Electronics Engineers "],"department":[{"_id":"DEP4018"},{"_id":"DEP1308"},{"_id":"DEP4028"}],"abstract":[{"lang":"eng","text":"Cyber-physical production systems have emerged with the rise of Industry 4.0 in different industrial fields.

This article reviews a cognitive architecture for Artificial Intelligence, which has been developed to establish a standard framework for integrating AI solutions into existing production processes. Given that machines in these processes continuously generate large streams of data, Online Machine Learning (OML) is identified as a crucial extension to the existing architecture. To substantiate this claim, real-world experiments using a slitting machine are conducted, to compare the performance of OML to traditional Batch Machine Learning. The assessment of contemporary OML algorithms using a real production system is a fundamental innovation in this research. The evaluations clearly indicate that OML adds significant value to CPS, and it is strongly recommended as an extension of related architectures, such as the cognitive architecture for AI discussed in this article. Additionally, surrogate-model-based optimization is employed, to determine the optimal hyperparameter settings for the corresponding OML algorithms, aiming to achieve peak performance in their respective tasks."}],"keyword":["machine learning","online algorithms","cyber-physical production systems","surrogate-based optimization"],"publisher":"MDPI AG","type":"scientific_journal_article","date_updated":"2025-06-26T07:50:56Z","doi":"10.3390/app132011506","external_id":{"isi":["001096019200001"]},"issue":"20","publication":" Applied Sciences : open access journal","article_number":"11506","_id":"12806","place":"Basel","citation":{"ieee":"A.

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"}],"type":"scientific_journal_article","publisher":"MDPI AG","issue":"5","date_updated":"2024-05-21T09:30:15Z","doi":"10.3390/pr10050883"},{"status":"public","department":[{"_id":"DEP6017"},{"_id":"DEP6020"}],"year":"2022","user_id":"83781","abstract":[{"text":"For the optimization of the impinging round jet, the pressure force coefficient and drying energy consumption on the moving curved surface are set as the objective functions to be minimized simultaneously.

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."}],"page":"21-48","keyword":["Gaussian processes","Bayes optimization","Pareto optimization","multi-objective","cell culture","seed train"],"status":"public","year":"2022","user_id":"83781","department":[{"_id":"DEP4000"}],"date_updated":"2023-08-16T09:24:16Z","doi":"https://doi.org/10.3390/pr10050883","quality_controlled":"1","editor":[{"last_name":"Pörtner","full_name":"Pörtner, Ralf","first_name":"Ralf"},{"full_name":"Möller, Johannes","last_name":"Möller","first_name":"Johannes"}],"publisher":"MDPI","type":"book_chapter","_id":"10193","publication":"Bioprocess Systems Engineering Applications in Pharmaceutical Manufacturing","series_title":"Processes : open access journal","title":"Designing robust biotechnological processes regarding variabilities using multi-objective optimization applied to a biopharmaceutical seed train design","citation":{"ama":"Hernández Rodriguez T, Sekulic A, Lange-Hegermann M, Frahm B.

Common powertrain configurations of PHEVs (i.e., the configuration of the combustion engine, electric motor, and transmission) can be operated either in series, parallel, or power split hybrid mode, whereas powertrain configurations with multimode transmissions enable switching between those modes during vehicle operation. Hence, depending on the current operation state of the vehicle, the most appropriate mode in terms efficiency can be selected. This, however, requires an operating strategy, which controls the mode selection as well as the torque distribution between the combustion engine and electric motor with the aim of optimal battery depletion and minimal fuel consumption. A well-known approach is the equivalent consumption minimization strategy (ECMS). It can be applied by using optimizations based on a prediction of the future driving behavior. Since the outcome of the ECMS depends on the quality of this prediction, it is crucial to know how accurate the predictions must be in order to obtain acceptable results. In this contribution, various prediction methods and real-time capable ECMS implementations are analyzed and compared in terms of the achievable fuel economy. The basis for the analysis is a holistic model of a state-of-the-art PHEV powertrain configuration, comprising the multimode transmission, corresponding powertrain components, and representative real-world driving data.","lang":"eng"}],"department":[{"_id":"DEP6020"}],"user_id":"83781","year":"2022","status":"public"},{"department":[{"_id":"DEP5023"}],"year":"2021","user_id":"83781","status":"public","keyword":["Cognition","Industry 40","Big data platform","Machine learning","CPPS","Optimization","Algorithm selection","Simulation"],"page":"3513-3532","abstract":[{"lang":"eng","text":"his paper presents the cognitive module of the Cognitive Architecture for Artificial Intelligence (CAAI) in cyber-physical production systems (CPPS).

Based on these evaluations, the pipelines are automatically adapted if necessary. The modular design with well-defined interfaces enables the reusability and extensibility of pipeline components. A big data platform implements this modular design supported by technologies such as Docker, Kubernetes, and Kafka for virtualization and orchestration of the individual components and their communication. The implementation of the architecture is evaluated using a real-world use case. The prototypic implementation is accessible on GitHub and contains a demonstration.","lang":"eng"}],"page":"609-626","keyword":["CPPS","Artificial intelligence","Industry 40","Reference architecture","Optimization","SMBO","Cognition","Big data platform","Modularization","AutoML"],"status":"public","year":"2020","user_id":"83781","department":[{"_id":"DEP5023"}],"title":"CAAI -- A Cognitive Architecture to Introduce Artificial Intelligence in Cyber-Physical Production Systems","citation":{"chicago-de":"Fischbach, Andreas, Jan Strohschein, Andreas Bunte, Jörg Stork, Heide Faeskorn-Woyke, Natalia Moriz und Thomas Bartz-Beielstein. 2020.

Therefore, we present a method that incorporates Hardware-in-the-Loop simulations where virtual components as models are coupled to real and experimental facilities in real time. By including experimental components, a higher validity can be obtained and the practical applicability of renewable energy scenario can be discussed more profoundly. In this paper, the considered energy system consists of an experimental biocatalytic methanation reactor, a real photovoltaic park, a regenerative fuel cell and short-term storage units to supply a residential district. A representative control sequence of the methanator is obtained by modeling the scenario as an optimal control problem. A first HIL simulation highlights that modifications of the instrumentation are required for a grid injection of the generated methane. The scientific approach can be applied to any energy system where some of the considered components are available as experimental or real facilities. Non-exisiting components are simply replaced by models. The presented approach helps to determine which parts or process parameters are crucial for the planed operation before the overall energy system is realized on a larger scale. (C) 2019 Elsevier Ltd.

Bionic design principles have already been introduced into general design approaches, and several topology optimization systems (TO) are available today to increase structural stiffness and to enable lightweight design. AM and TO, used in synergy, promise completely new application areas. However, staircase effects resulting from a layer-by-layer build process and unavoidable support structures which must be mechanically removed afterwards are disadvantageous with respect to surface texture and strength properties.\r\nThe present article addresses the question of how far the notches resulting from the staircase effect of Additive Manufacturing and the support structures removed decrease the strength of components. Most engineers try to follow the inner flow of forces in a part’s design by smoothening surfaces in notched areas. Considering this, a elected component is investigated with finite element analysis (FEA) with special regard for the concentration of tress arising from surface notch effects.
