Due to simplifications and the model-reality-gap physics-derived models frequently exhibit deviations from real-world-systems. Likewise, purely data-driven methods often do not generalise well enough and may violate physical laws. Recently Physics-Guided Neural Networks (PGNN) and physics-inspired loss functions separately have shown promising results to conquer these drawbacks. In this contribution we extend existing methods towards the identification of non-autonomous systems and propose a combined approach PGNN-L, which uses a PGNN and a physics-inspired loss term (-L) to successfully identify the system's dynamics, while maintaining the consistency with physical laws. The proposed method is demonstrated on two real-world nonlinear systems and outperforms existing techniques regarding complexity and reliability.","lang":"eng"}],"publication":"2022 3rd International Conference on Artificial Intelligence, Robotics and Control (AIRC)","type":"conference"},{"date_created":"2022-02-09T12:50:25Z","author":[{"full_name":"Hesse, Michael","id":"29222","last_name":"Hesse","first_name":"Michael"},{"first_name":"Matthias","last_name":"Hunstig","full_name":"Hunstig, Matthias"},{"id":"15402","full_name":"Timmermann, Julia","last_name":"Timmermann","first_name":"Julia"},{"first_name":"Ansgar","full_name":"Trächtler, Ansgar","id":"552","last_name":"Trächtler"}],"date_updated":"2024-11-13T08:44:17Z","conference":{"end_date":"2022-02-05","location":"Online","name":"11th International Conference on Pattern Recognition Applications and Methods","start_date":"2022-02-03"},"title":"Batch Constrained Bayesian Optimization for UltrasonicWire Bonding Feed-forward Control Design","publication_identifier":{"isbn":["978-989-758-549-4"]},"quality_controlled":"1","page":"383-394","citation":{"mla":"Hesse, Michael, et al. “Batch Constrained Bayesian Optimization for UltrasonicWire Bonding Feed-Forward Control Design.” Proceedings of the 11th International Conference on Pattern Recognition Applications and Methods (ICPRAM), 2022, pp. 383–94.","bibtex":"@inproceedings{Hesse_Hunstig_Timmermann_Trächtler_2022, title={Batch Constrained Bayesian Optimization for UltrasonicWire Bonding Feed-forward Control Design}, booktitle={Proceedings of the 11th International Conference on Pattern Recognition Applications and Methods (ICPRAM)}, author={Hesse, Michael and Hunstig, Matthias and Timmermann, Julia and Trächtler, Ansgar}, year={2022}, pages={383–394} }","short":"M.

A high frequency oscillation causes a metallurgical bond deformation in\r\nthe contact area. Due to the numerous physical influencing factors, it is very difficult to accurately capture\r\nthis process in a model. Therefore, our goal is to determine a suitable feed-forward control strategy for the\r\nbonding process even without detailed model knowledge. We propose the use of batch constrained Bayesian\r\noptimization for the control design. Hence, Bayesian optimization is precisely adapted to the application of\r\nbonding: the constraint is used to check one quality feature of the process and the use of batches leads to\r\nmore efficient experiments. Our approach is suitable to determine a feed-forward control for the bonding\r\nprocess that provides very high quality bonds without using a physical model. We also show that the quality\r\nof the Bayesian optimization based control outperforms random search as well as manual search by a user.\r\nUsing a simple prior knowledge model derived from data further improves the quality of the connection.\r\nThe Bayesian optimization approach offers the possibility to perform a sensitivity analysis of the control\r\nparameters, which allows to evaluate the influence of each control parameter on the bond quality. In summary,\r\nBayesian optimization applied to the bonding process provides an excellent opportunity to develop a feedforward\r\ncontrol without full modeling of the underlying physical processes."}]},{"citation":{"ama":"Schaffer M, Lea B, Schulte C, Buhl HM.

In this model, active robots move on a set of passive tiles, called configuration, with the geometric shape of rhombic dodecahedra on the adjacency graph of the face-centered cubic sphere-packing. We show that the exploration problem is equally hard in the hybrid model and in three-dimensional mazes, in which tiles have the shape of cubes and are positioned at the vertices of $\\mathbb{Z}^3$. Thereby, a single robot with a constant number of pebbles cannot solve this problem in the hybrid model on arbitrary configurations. We provide algorithms for a robot with two pebbles that solve the exploration problem in the subclass of compact configurations of size $n$ in $\\O(n^3)$ rounds. Further, we investigate the robot's capabilities of detection and hull construction in terms of restricted orientation convexity. We show that a robot without any pebble can detect strong $\\O$-convexity in $\\O(n)$ rounds, but cannot detect weak $\\O$-convexity, not even if provided with a single pebble. Assuming that a robot can construct tiles from scratch and deconstruct previously constructed tiles, we show that the strong $\\O$-hull of any given configuration of size $n$ can be constructed in $\\O(n^4)$ rounds, even if the robot cannot distinguish constructed from native tiles.","lang":"eng"}],"file":[{"content_type":"application/pdf","relation":"main_file","date_created":"2021-09-29T12:34:47Z","creator":"liedtke","date_updated":"2021-09-29T12:34:47Z","file_id":"25128","access_level":"local","file_name":"Master - Thesis.pdf","file_size":10114825}],"status":"public","type":"mastersthesis"},{"author":[{"first_name":"Sebastian","full_name":"Gottschalk, Sebastian","id":"47208","last_name":"Gottschalk"},{"orcid":"0000-0002-5967-833X","last_name":"Yigitbas","id":"8447","full_name":"Yigitbas, Enes","first_name":"Enes"},{"first_name":"Alexander","full_name":"Nowosad, Alexander","last_name":"Nowosad"},{"full_name":"Engels, Gregor","last_name":"Engels","first_name":"Gregor"}],"date_created":"2021-04-20T13:23:41Z","oa":"1","date_updated":"2022-01-06T06:55:08Z","publisher":"Springer","doi":"10.1007/978-3-030-79186-5_17","title":"Situation-specific Business Model Development Methods for Mobile App Developers","has_accepted_license":"1","citation":{"bibtex":"@inproceedings{Gottschalk_Yigitbas_Nowosad_Engels_2021, title={Situation-specific Business Model Development Methods for Mobile App Developers}, DOI={10.1007/978-3-030-79186-5_17}, booktitle={Enterprise, Business-Process and Information Systems Modeling}, publisher={Springer}, author={Gottschalk, Sebastian and Yigitbas, Enes and Nowosad, Alexander and Engels, Gregor}, year={2021} }","short":"S.

Existing development methods for these business models do not specifically focus that the development process profoundly depends on the situation (e.g., market size, regulations) of the mobile app developer.

In software engineering, situational method engineering is used for software projects to configure a development method out of a method repository based on the project situation. Analogously, we support creating situation-specific business model development methods with a method base and new user roles. Here, the method engineer obtains the knowledge of the domain expert and stores it in the method base as elements, building blocks, and patterns. The expert knowledge is derived from a grey literature review on mobile development processes. After this, the method engineer constructs the development method based on the described situation of the business developer.

To handle different kinds of uncertainties, a novel Multi-Model-Particle Filtering-based prognostic approach is developed and evaluated by the use case of rubber-metal-elements. These elements are maintained preventively due to the strong influence of uncertainties on their behavior. In this paper, two measurement quantities are compared concerning their ability to establish a prediction of the remaining useful lifetime of the monitored elements and the influence of present uncertainties. Based on three performance indices, the results are evaluated. A comparison with predictions of a classical Particle Filter underlines the superiority of the developed Multi-Model-Particle Filter.

It also investigates what knowledge farmers require on digitalised farms and how they acquire it. Dairy farming was used as domain of investigation since it, unlike other industries, has strongly been affected by digitalisation throughout the last years.\r\n\r\nMethod: Exploratory interviews with 10 livestock farmers working on digitalised dairy farms were analysed using qualitative content analysis. A deductive and inductive coding strategy was used. \r\n\r\nFindings: Farming work has changed from more manual tasks towards symbol manipulation and data processing. Farmers must be able to use computers and other digital devices to retrieve and analyse sensor data that allow them to monitor and control the processes on their farm. For this new kind of work, farmers require elaborated mental models that link traditional farming knowledge with knowledge about digital systems, including a strong understanding of production processes underlying their farm. Learning is mostly based on instructions offered by manufacturers of the new technology as well as informal and non-formal learning modes. Even younger farmers report that digital technology was not sufficiently covered in their (vocational) degrees. In general, farmers emphasises the positive effects of digitalisation both on their working as well as private life. \r\n\r\nConclusions: Farmers should be aware of the opportunities as well as the potential drawbacks of the digitalisation of work processes in agriculture. Providers of agricultural education (like vocational schools or training institutes) need to incorporate the knowledge and skills required to work in digitalised environments (e.g., data literacy) in their syllabi. Further studies are required to assess how digitalisation changes farming practices and what knowledge as well as skills linked to these developments are required in the future.","lang":"eng"}],"type":"journal_article","publication":"International Journal for Research in Vocational Education and Training","doi":"10.13152/IJRVET.8.2.4.","title":"Digitalisation in Agriculture: Knowledge and Learning Requirements of German Dairy Farmers","date_created":"2023-01-04T10:08:59Z","author":[{"first_name":"Michael","id":"30984","full_name":"Goller, Michael","orcid":"0000-0002-2820-9178","last_name":"Goller"},{"first_name":"Carina","last_name":"Caruso","full_name":"Caruso, Carina","id":"23123"},{"first_name":"Christian","orcid":"https://orcid.org/0000-0002-3570-7626","last_name":"Harteis","id":"27503","full_name":"Harteis, Christian"}],"volume":8,"date_updated":"2023-01-06T12:17:27Z","citation":{"ama":"Goller M, Caruso C, Harteis C.

In general, those solutions utilize model-based or data-driven methods to diagnose the current state or predict future states of monitored technical systems. However, both methods have their advantages and drawbacks. Combining both methods can improve uncertainty consideration and accuracy. Different combination approaches of those hybrid methods exist to exploit synergy effects. The choice of an appropriate approach depends on different requirements and the goal behind the selection of a hybrid approach.\r\n\r\n \r\n\r\nIn this work, the hybrid approach for estimating remaining useful lifetime takes potential uncertainties into account. Therefore, a data-driven estimation of new measurements is integrated within a model-based method. To consider uncertainties within the system, a differentiation between different system behavior is realized throughout diverse states of degradation.\r\n\r\nThe developed hybrid prediction approach bases on a particle filtering method combined with a machine learning method, to estimate the remaining useful lifetime of technical systems. Particle filtering as a Monte Carlo simulation technique is suitable to map and propagate uncertainties. Moreover, it is a state-of-the-art model-based method for predicting remaining useful lifetime of technical systems. To integrate uncertainties a multi-model particle filtering approach is employed. In general, resampling as a part of the particle filtering approach has the potential to lead to an accurate prediction. However, in the case where no future measurements are available, it may increase the uncertainty of the prediction. By estimating new measurements, those uncertainties are reduced within the data-driven part of the approach. Hence, both parts of the hybrid approach strive to account for and reduce uncertainties.\r\n\r\n \r\n\r\nRubber-metal-elements are employed as a use-case to evaluate the developed approach. Rubber-metal-elements, which are used to isolate vibrations in various systems, such as railways, trucks and wind turbines, show various uncertainties in their behavior and their degradation. Those uncertainties are caused by diverse inner and outer factors, such as manufacturing influences and operating conditions. By expert knowledge the influences are described, analyzed and if possible reduced. However, the remaining uncertainties are considered within the hybrid prediction method. Relative temperature is the selected measurand to describe the element’s degradation. In lifetime tests, it is measured as the difference between the element’s temperature and the ambient temperature. Thereby, the influence of the ambient temperature on the element’s temperature is taken into account. Those elements show three typical states of degradation that are identified within the temperature measurements. Depending on the particular state of degradation a new measurement is estimated within the hybrid approach to reduce potential uncertainties.\r\n\r\nFinally, the performance of the developed hybrid method is compared to a model-based method for estimating the remaining useful lifetime of the same elements. Suitable performance indices are implemented to underline the differences between the results.","lang":"eng"}]},{"type":"conference","editor":[{"first_name":"Phuc","full_name":"Do, Phuc","last_name":"Do"},{"full_name":"King, Steve","last_name":"King","first_name":"Steve"},{"first_name":"Olga","last_name":"Fink","full_name":"Fink, Olga"}],"status":"public","_id":"27111","user_id":"9557","department":[{"_id":"151"}],"publication_status":"published","citation":{"apa":"Aimiyekagbon, O.

However, an increase in model accuracy with state-of-the-art methods, such as deep convolutional neural networks, results in less interpretability and transparency. Due to the ease of implementation, interpretation and transparency to both domain experts and non-experts, a rule-based method is proposed in this paper, for prognostics and health management (PHM) and specifically for diagnostics. The proposed method utilizes the most relevant sensor signals acquired via feature extraction and selection techniques and expert knowledge. As a case study, the presented method is evaluated on data from a real-world quality control set-up provided by the European prognostics and health management society (PHME) at the conference’s 2021 data challenge.

A number of studies compare SPARQL federation engines across different performance metrics, including query runtime, result set completeness and correctness, number of sources selected and number of requests sent. Albeit informative, these metrics are generic and unable to quantify and evaluate the accuracy of the cardinality estimators of cost-based federation engines. To thoroughly evaluate cost-based federation engines, the effect of estimated cardinality errors on the overall query runtime performance must be measured. In this paper, we address this challenge by presenting novel evaluation metrics targeted at a fine-grained benchmarking of cost-based federated SPARQL query engines. We evaluate five cost-based federated SPARQL query engines using existing as well as novel evaluation metrics by using LargeRDFBench queries. Our results provide a detailed analysis of the experimental outcomes that reveal novel insights, useful for the development of future cost-based federated SPARQL query processing engines."}],"date_created":"2021-10-01T06:52:52Z","publisher":"ISO Press","title":"An Empirical Evaluation of Cost-based Federated SPARQL Query Processing Engines","issue":"6","year":"2021"},{"citation":{"apa":"Gottschalk, S., Yigitbas, E., Schmidt, E., & Engels, G.

For this, we previously developed an approach for model-based AR-assisted product configuration based on the concept of Dynamic Software Product Lines. In this demonstration paper, we present the corresponding tool support ProConAR in the form of a Product Modeler and a Product Configurator. While the Product Modeler is an Angular web app that splits products (e.g. table) up into atomic parts (e.g. tabletop, table legs, funnier) and saves it within a configuration model, the Product Configurator is an Android client that uses the configuration model to place different product configurations within the environment of the customer.

This approach involves so-called Huygens' box as an efficient radiation model inside an electromagnetic (EM) simulation tool and then transforms the scanned NF measured data into the FF. For this, the basic idea of the Huygens'box principle and the NF-to-FF transformation are briefly presented. The NF is measured on the Huygens' box around a device under test using anNF scanner, recording the magnitude and phase of the site-related magnetic and electric components. A comparison between a fullwave simulation and the measurement results shows a good similarity in both the NF and the simulated and transformed FF.Thus, this method is applicable to predict the FF behaviour of any electronic system by measuring the NF. With this knowledge, the RF design can be improved due to allowing a significant reduction of EM compatibility failure at the end of the development flow. In addition, the very efficient FF radiation model can be used for detailed investigations in various environments and the impact of such an equivalent radiation source on other electronic systems can be assessed.","lang":"eng"}],"publication":"Tensorial Analysis of Networks (TAN) Modelling for PCB Signal Integrity and EMC Analysis"},{"abstract":[{"text":"The continuous innovation of its business models is an important task for a company to stay competitive. During this process, the company has to validate various hypotheses about its business models by adapting to uncertain and changing customer needs effectively and efficiently.

SPLs reduce the time to market by deriving products for customers with changing requirements using a common set of features, structured as a feature model. Analogously, we support the process of business model adaptation by applying the engineering process of SPLs to the structure of the Business Model Canvas (BMC). We call this concept a Business Model Decision Line (BMDL). The BMDL matches business domain knowledge in the form of a feature model with customer needs to derive hypotheses about the business model together with experiments for validation. Our approach is effective by providing a comprehensive overview of possible business model adaptations and efficient by reusing experiments for different hypotheses.

This adaptation is part of the research discipline of Hypotheses Engineering (HE) where customer needs can be seen as hypotheses that need to be tested iteratively by conducting experiments together with the customer. So far, modeling support and associated traceability of this iterative process are missing. Both, in turn, are important to document the adaptation to the customer needs and identify experiments that provide most evidence to the customer needs. To target this issue, we introduce a model-based HE approach with a twofold contribution: First, we develop a modeling language that models hypotheses and experiments as interrelated hierarchies together with a mapping between them. While the hypotheses are labeled with a score level of their current evidence, the experiments are labeled with a score level of maximum evidence that can be achieved during conduction. Second, we provide an iterative process to determine experiments that offer the most evidence improvement to the modeled hypotheses. We illustrate the usefulness of the approach with an example of testing the business model of a mobile application.","lang":"eng"}],"file":[{"date_updated":"2020-07-14T09:28:33Z","date_created":"2020-07-14T09:25:30Z","creator":"sego","file_size":267658,"file_name":"BMSD20.pdf","access_level":"open_access","file_id":"17380","content_type":"application/pdf","relation":"main_file"}],"publication":"Business Modeling and Software Design","ddc":["006"],"keyword":["Hypothesis Engineering","Model-based","Customer Need Adaptation","Business Model","Product Features"],"language":[{"iso":"eng"}],"citation":{"mla":"Gottschalk, Sebastian, et al. “Model-Based Hypothesis Engineering for Supporting Adaptation to Uncertain Customer Needs.” Business Modeling and Software Design, edited by Boris Shishkov, vol. 391, Springer International Publishing, 2020, pp. 276–86, doi:10.1007/978-3-030-52306-0_18.","bibtex":"@inproceedings{Gottschalk_Yigitbas_Engels_2020, series={Lecture Notes in Business Information Processing}, title={Model-based Hypothesis Engineering for Supporting Adaptation to Uncertain Customer Needs}, volume={391}, DOI={10.1007/978-3-030-52306-0_18}, booktitle={Business Modeling and Software Design}, publisher={Springer International Publishing}, author={Gottschalk, Sebastian and Yigitbas, Enes and Engels, Gregor}, editor={Shishkov, BorisEditor}, year={2020}, pages={276–286}, collection={Lecture Notes in Business Information Processing} }","short":"S.

Accounting for the widely acknowledged limitations of pure citation analysis, we adopt a knowledge-based perspective on scientific impact to develop a methodology for content-based citation analysis which allows determining how papers have enabled knowledge development in subsequent research (knowledge impact). As knowledge development differs between research genres, we develop a new knowledgebased citation analysis methodology for the genre of standalone literature reviews (LRs). We apply the suggested methodology to the IS business value domain by manually coding 22 LRs and 1,228 citing papers (CPs) and show that the results challenge the assumption that citations indicate knowledge impact. We derive implications for distinguishing knowledge impact from citation impact in the LR genre. Finally, we develop recommendations for authors of LRs, scientific evaluation committees and editorial boards of journals how to apply and benefit from the suggested methodology, and we discuss its efficiency and automatization.","lang":"eng"}],"type":"working_paper","main_file_link":[{"url":"https://ssrn.com/abstract=3581789","open_access":"1"}],"title":"Distinguishing Knowledge Impact from Citation Impact: A Methodology for Analysing Knowledge Impact for the Literature Review Genre","date_created":"2020-05-19T15:12:33Z","author":[{"last_name":"Schryen","id":"72850","full_name":"Schryen, Guido","first_name":"Guido"},{"first_name":"Gerit","last_name":"Wagner","full_name":"Wagner, Gerit"},{"first_name":"Alexander","full_name":"Benlian, Alexander","last_name":"Benlian"}],"date_updated":"2022-01-06T06:53:02Z","oa":"1","citation":{"ama":"Schryen G, Wagner G, Benlian A.

We here present our dataset consisting of German physician reviews, a sensitive and linguistically complex field. Furthermore, we describe the annotation process of a dataset for supervised learning with neural networks. Moreover, we introduce our model for extracting and classifying aspect phrases in one step, which obtains an F1-score of 80%.
