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"}]},{"publisher":"Springer","_id":"21639","user_id":"47208","ddc":["000"],"status":"public","has_accepted_license":"1","oa":"1","file_date_updated":"2021-07-20T16:20:15Z","citation":{"bibtex":"@inproceedings{Gottschalk_Yigitbas_Nowosad_Engels_2021, title={Situation-specific Business Model Development Methods for Mobile App Developers}, DOI={<a href=\"https://doi.org/10.1007/978-3-030-79186-5_17\">10.1007/978-3-030-79186-5_17</a>}, 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.

Here, domain experts can guide the choices of tasks and decisions with their knowledge. Nevertheless, this knowledge needs to match the situation of the company (e.g., financial resources) and the application domain of the product/service (e.g., mobile app) to reduce the risk of developing ineffective business models with low market penetration. This is not covered by one-size-fits-all development methods without tailoring before the enaction.\r\nTherefore, we conduct a design science study to create a situation-specific development approach for business models. Based on situational method engineering and our previous work in storing knowledge of methods and models in distinct repositories, this paper shows the situation-specific composition and enaction of business model development methods. First, the method engineer composes the development method out of both repositories based on the situational context. Second, the business developer enacts the method and develops the business model.

Major innovations of the revised VDI guideline 2206 for developing mechatronic systems are systems thinking as a core element and six checkpoints for structuring deliverables along the V-Model. These checkpoints serve for orientation in result progress and thus enable a structured and complete development process. However, tasks and checkpoints of the new guideline focus on the product development itself without integrating the development of related CPPS, enabling optimization simultaneously to system development. Implications are derived by a three-step analysis. The paper at hand contributes fundamental extensions of the checkpoint questions regarding integrated CPPS development.

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."}],"main_file_link":[{"url":"https://papers.phmsociety.org/index.php/phme/article/view/2843","open_access":"1"}],"language":[{"iso":"eng"}],"doi":"https://doi.org/10.36001/phme.2021.v6i1.2843 ","title":"Hybrid Prediction Method for Remaining Useful Lifetime Estimation Considering Uncertainties","year":"2021","publication_identifier":{"unknown":["978-1-936263-34-9"]},"author":[{"full_name":"Bender, Amelie","first_name":"Amelie","last_name":"Bender","id":"54290"},{"first_name":"Walter","last_name":"Sextro","full_name":"Sextro, Walter","id":"21220"}],"publication_status":"published","date_updated":"2023-09-22T07:19:48Z","intvolume":"         6","oa":"1","citation":{"bibtex":"@inproceedings{Bender_Sextro_2021, title={Hybrid Prediction Method for Remaining Useful Lifetime Estimation Considering Uncertainties}, volume={6}, DOI={<a href=\"https://doi.org/10.36001/phme.2021.v6i1.2843 \">https://doi.org/10.36001/phme.2021.v6i1.2843 </a>}, number={1}, booktitle={Proceedings of the European Conference of the PHM Society 2021}, author={Bender, Amelie and Sextro, Walter}, editor={Do, Phuc  and King, Steve and Fink,  Olga}, year={2021} }","ama":"Bender A, Sextro W.

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.

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"}],"date_created":"2021-03-18T13:49:49Z","department":[{"_id":"485"}],"type":"book_chapter","keyword":["Huygens' box","NF-to-FF transformation","efficient FF radiation model","FF behaviour","EMI assessment","PCB","near-field measurements","efficient radiation model","far-field behaviour","RF design process","far-field prediction","Huygens'box principle","fullwave simulation","electronic system radiation","equivalent radiation source","electromagnetic simulation tool","near-field scan data","EM compatibility failure reduction"]},{"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. This adaptation, in turn, can be supported by the concept of Software Product Lines (SPLs). 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. We implement our approach in a tool and illustrate the usefulness with an example of developing business models for a mobile application.","lang":"eng"}],"publication":"Proceedings of the 22nd IEEE International Conference on Business Informatics","department":[{"_id":"66"}],"type":"conference","keyword":["Business Model Decision Line","Business Model Adaptation","Hypothesis-driven Adaptation","Software Product Line","Feature Model"],"date_created":"2020-05-04T12:16:54Z","file":[{"date_created":"2020-07-14T09:33:00Z","creator":"sego","content_type":"application/pdf","file_id":"17383","access_level":"open_access","file_size":569290,"file_name":"CBI.pdf","date_updated":"2020-07-14T09:33:00Z","relation":"main_file"}],"date_updated":"2022-01-06T06:52:59Z","author":[{"last_name":"Gottschalk","first_name":"Sebastian","full_name":"Gottschalk, Sebastian","id":"47208"},{"id":"5281","last_name":"Rittmeier","first_name":"Florian","full_name":"Rittmeier, Florian"},{"id":"107","last_name":"Engels","first_name":"Gregor","full_name":"Engels, Gregor"}],"year":"2020","title":"Hypothesis-driven Adaptation of Business Models based on Product Line Engineering","doi":"10.1109/CBI49978.2020.00022","language":[{"iso":"eng"}],"project":[{"name":"SFB 901","_id":"1"},{"name":"SFB 901 - Project Area C","_id":"4"},{"name":"SFB 901 - Subproject C5","_id":"17"}],"citation":{"ieee":"S.

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."}],"series_title":"Lecture Notes in Business Information Processing","language":[{"iso":"eng"}],"doi":"10.1007/978-3-030-52306-0_18","title":"Model-based Hypothesis Engineering for Supporting Adaptation to Uncertain Customer Needs","year":"2020","author":[{"full_name":"Gottschalk, Sebastian","first_name":"Sebastian","last_name":"Gottschalk","id":"47208"},{"full_name":"Yigitbas, Enes","last_name":"Yigitbas","orcid":"0000-0002-5967-833X","first_name":"Enes","id":"8447"},{"full_name":"Engels, Gregor","last_name":"Engels","first_name":"Gregor","id":"107"}],"date_updated":"2022-01-06T06:52:59Z","intvolume":"       391"},{"intvolume":"         1","date_updated":"2022-04-25T07:49:50Z","author":[{"full_name":"Otroshi, Mortaza","orcid":"0000-0002-8652-9209","last_name":"Otroshi","first_name":"Mortaza","id":"71269"},{"full_name":"Rossel, Moritz","first_name":"Moritz","last_name":"Rossel"},{"full_name":"Meschut, Gerson","last_name":"Meschut","first_name":"Gerson","orcid":"0000-0002-2763-1246","id":"32056"}],"year":"2020","title":"Stress state dependent damage modeling of self-pierce riveting process simulation using GISSMO damage model","doi":"10.1016/j.jajp.2020.100015","language":[{"iso":"eng"}],"main_file_link":[{"open_access":"1"}],"publication":"Journal of Advanced Joining Processes","department":[{"_id":"157"}],"keyword":["Self-pierce riveting","Ductile fracture","Damage modeling","GISSMO damage model"],"type":"journal_article","date_created":"2020-10-20T14:49:15Z","status":"public","volume":1,"user_id":"71269","_id":"20143","publisher":"Elsevier","quality_controlled":"1","citation":{"short":"M.

The key design principle of SMBO is a substitution of the true objective function by a surrogate, which is used to propose the point(s) to be evaluated next. SMBO algorithms are intrinsically modular, leaving the user with many important design choices. Significant research efforts go into understanding which settings perform best for which type of problems. Most works, however, focus on the choice of the model, the acquisition function, and the strategy used to optimize the latter. The choice of the initial sampling strategy, however, receives much less attention. Not surprisingly, quite diverging recommendations can be found in the literature. We analyze in this work how the size and the distribution of the initial sample influences the overall quality of the efficient global optimization (EGO) algorithm, a well-known SMBO approach. While, overall, small initial budgets using Halton sampling seem preferable, we also observe that the performance landscape is rather unstructured. We furthermore identify several situations in which EGO performs unfavorably against random sampling. Both observations indicate that an adaptive SMBO design could be beneficial, making SMBO an interesting test-bed for automated algorithm design.","lang":"eng"}],"extern":"1"},{"oa":"1","citation":{"short":"S.

Usually, for parallel-plate geometries, the tip-to-tip distance is used for calculation of absolute rheological values, which implies that there is no flow behind this distance. However, several studies show that this is not true. Therefore, the measuring gap needs to be corrected by adding the effective gap extension    δ    to the prescribed gap height    H    in order to obtain absolute rheological properties. In this paper, we determine the effective gap extension    δ    for different structures and fluids (Newtonian, shear thinning, and model suspensions that can be adjusted to the behavior of real fluids) and compare the corrected values to reference data. We observe that for Newtonian fluids a gap- and material-independent correction function can be derived for every measuring system, which is also applicable to suspensions, but not to shear thinning fluids. Since this relation appears to be mainly dependent on the characteristics of flow behaviour, we show that the calibration of structured measuring systems is possible with Newtonian fluids and then can be transferred to suspensions up to a certain particle content.</jats:p>"}],"language":[{"iso":"eng"}],"main_file_link":[{"url":"https://www.mdpi.com/1996-1944/13/2/467","open_access":"1"}],"article_number":"467","doi":"10.3390/ma13020467","publication_identifier":{"issn":["1996-1944"]},"author":[{"id":"38243","full_name":"Pawelczyk, Sebastian","last_name":"Pawelczyk","first_name":"Sebastian"},{"full_name":"Kniepkamp, Marieluise","first_name":"Marieluise","last_name":"Kniepkamp"},{"id":"3959","full_name":"Jesinghausen, Steffen","last_name":"Jesinghausen","orcid":"https://orcid.org/0000-0003-2611-5298","first_name":"Steffen"},{"last_name":"Schmid","first_name":"Hans-Joachim","full_name":"Schmid, Hans-Joachim","id":"464"}],"title":"Absolute Rheological Measurements of Model Suspensions: Influence and Correction of Wall Slip Prevention Measures","year":"2020","article_type":"original","date_updated":"2023-01-17T07:45:59Z","publication_status":"published"},{"year":"2019","status":"public","title":"Topic Modeling as a Strategy of Inquiry in Organizational Research: A Tutorial With an Application Example on Organizational Culture","author":[{"full_name":"Schmiedel, T.","last_name":"Schmiedel","first_name":"T."},{"id":"72849","full_name":"Müller, Oliver","first_name":"Oliver","last_name":"Müller"},{"full_name":"vom Brocke, J.","first_name":"J.","last_name":"vom Brocke"}],"date_updated":"2022-01-06T07:01:18Z","page":"941--968 ","_id":"4682","language":[{"iso":"eng"}],"doi":"https://doi.org/10.1177/1094428118773858","user_id":"72849","publication":"Organizational Research Methods","citation":{"chicago":"Schmiedel, T., Oliver Müller, and J. vom Brocke. “Topic Modeling as a Strategy of Inquiry in Organizational Research: A Tutorial With an Application Example on Organizational Culture.” <i>Organizational Research Methods</i>, 2019, 941--968. <a href=\"https://doi.org/10.1177/1094428118773858\">https://doi.org/10.1177/1094428118773858</a>.","short":"T.
