Here, existing approaches and tools do not focus on the company’s situation in which the development takes place (e.g., financial resources, product type). To tackle this challenge, we used design science research to develop a situation-specific business model development approach that contains three stages: First, existing knowledge in terms of tasks to do (e.g., analyze competitive advantage), and decisions to be made (e.g., social media marketing) are stored in repositories. Second, the knowledge is used to compose a development method based on the company’s situation. Third, the development method is enacted to develop a business model. This demonstration paper presents a tool-support called Situational Business Model Developer that supports all stages of our approach. We release the tool under open-source and evaluate it with a case study on developing business models for mobile apps."}],"status":"public","_id":"29839","project":[{"_id":"1","name":"SFB 901: SFB 901"},{"name":"SFB 901 - C: SFB 901 - Project Area C","_id":"4"},{"name":"SFB 901 - C5: SFB 901 - Subproject C5","_id":"17"}],"department":[{"_id":"66"},{"_id":"534"}],"user_id":"47208","keyword":["Business Model Development","Situational Method Engineering","Tool Support"],"language":[{"iso":"eng"}]},{"status":"public","type":"conference","file_date_updated":"2022-07-04T12:34:52Z","project":[{"name":"SFB 901: SFB 901","_id":"1"},{"_id":"4","name":"SFB 901 - C: SFB 901 - Project Area C"},{"_id":"17","name":"SFB 901 - C5: SFB 901 - Subproject C5"}],"_id":"29842","user_id":"47208","department":[{"_id":"66"},{"_id":"534"}],"citation":{"ieee":"S.

This discovery can be achieved with continuous experimentation, testing different software variants with distinct user groups, and deploying the superior variant for all users. However, existing approaches do not focus on explicit modeling of variants and experiments, which offers advantages such as traceability of decisions and combinability of experiments. Therefore, our vision is the provision of model-driven continuous experimentation, which provides the developer with a framework for structuring the experimentation process. For that, we introduce the overall concept, apply it to the experimentation on component-based software architectures and point out future research questions. In particular, we show the applicability by combining feature models for modeling the software variants, users, and experiments (i.e., model-driven) with MAPE-K for the adaptation (i.e., continuous experimentation) and implementing the concept based on the component-based Angular framework."}],"file":[{"date_updated":"2022-07-04T12:34:52Z","date_created":"2022-07-04T12:33:18Z","creator":"sego","file_size":183185,"access_level":"open_access","file_id":"32322","file_name":"ICSA_CR.pdf","content_type":"application/pdf","relation":"main_file"}],"publication":"Proceedings of the 18th International Conference on Software Architecture Companion ","ddc":["000"],"keyword":["continuous experimentation","model-driven","component-based software architectures","self-adaptation"],"language":[{"iso":"eng"}],"year":"2022","title":"Model-driven Continuous Experimentation on Component-based Software Architectures ","publisher":"IEEE","date_created":"2022-02-15T07:32:10Z"},{"date_created":"2022-01-11T08:43:26Z","publisher":"IEEE","title":"Use What You Know: Network and Service Coordination Beyond Certainty","quality_controlled":"1","year":"2022","language":[{"iso":"eng"}],"keyword":["network management","service management","AI","Monte Carlo Tree Search","model-based","QoS"],"ddc":["004"],"publication":"IEEE/IFIP Network Operations and Management Symposium (NOMS)","file":[{"file_size":528653,"access_level":"open_access","file_name":"author_version.pdf","file_id":"29222","date_updated":"2022-01-11T08:39:57Z","date_created":"2022-01-11T08:39:57Z","creator":"stschn","relation":"main_file","content_type":"application/pdf"}],"abstract":[{"lang":"eng","text":"Modern services often comprise several components, such as chained virtual network functions, microservices, or\r\nmachine learning functions. Providing such services requires to decide how often to instantiate each component, where to place these instances in the network, how to chain them and route traffic through them. \r\nTo overcome limitations of conventional, hardwired heuristics, deep reinforcement learning (DRL) approaches for self-learning network and service management have emerged recently. These model-free DRL approaches are more flexible but typically learn tabula rasa, i.e., disregard existing understanding of networks, services, and their coordination. \r\n\r\nInstead, we propose FutureCoord, a novel model-based AI approach that leverages existing understanding of networks and services for more efficient and effective coordination without time-intensive training. FutureCoord combines Monte Carlo Tree Search with a stochastic traffic model. This allows FutureCoord to estimate the impact of future incoming traffic and effectively optimize long-term effects, taking fluctuating demand and Quality of Service (QoS) requirements into account. Our extensive evaluation based on real-world network topologies, services, and traffic traces indicates that FutureCoord clearly outperforms state-of-the-art model-free and model-based approaches with up to 51% higher flow success ratios."}],"author":[{"last_name":"Werner","full_name":"Werner, Stefan","first_name":"Stefan"},{"first_name":"Stefan Balthasar","last_name":"Schneider","orcid":"0000-0001-8210-4011","full_name":"Schneider, Stefan Balthasar","id":"35343"},{"last_name":"Karl","id":"126","full_name":"Karl, Holger","first_name":"Holger"}],"date_updated":"2022-01-11T08:44:04Z","oa":"1","conference":{"name":"IEEE/IFIP Network Operations and Management Symposium (NOMS)","start_date":"2022-04-25","end_date":"2022-04-29","location":"Budapest"},"has_accepted_license":"1","citation":{"ieee":"S.

As piezoelectric elements transform electrical to mechanical energy and vice versa, equivalent circuit modeling is also described. After that, sample applications are delineated by the matter wherein ultrasound generates unique effects: incredible high pressure level as well in air as in water, micro-bubbles generating temperature peaks for very short time instances in fluids, acoustoplastic effect, enhancement of diffusion and recrystallization in solids, friction manipulation, incremental deformation and micro-cracking of surfaces, or even generation of macroscopic movements in motors.

Competence models in which modeling is integrated at least to some extent already exist in some of these disciplines. However, for the core component of graphical modeling, a competence model that illuminates the relevant competences in detail is still lacking. Therefore, we develop a competence model for graphical modeling with the aim to make teaching and especially assessments in the field more competence-oriented. This paper reports on the first two studies conducted to develop and validate the competence model for graphical modeling. In the first study, the structure of the competence model was developed based on theories and approaches of educational science. Competences relevant for graphical modeling were deductively derived from literature and existing university course descriptions using techniques of qualitative content analysis. The result of the first study is a preliminary competence model. In the second study, the preliminary competence model was reviewed by means of an expert rating in the modeling community. The competence model was revised and refined based on these findings and subsequent expert discussions. The main result of the investigation represents the competence model for graphical modeling (CMGM), which includes a total of 74 competence facets at different cognitive process levels in the five content areas of ”model understanding and interpreting”, ”model building and modifying”, ”values, attitudes, and beliefs”, ”metacognitive knowledge and skills”, and ”social-communicative skills”."}],"status":"public","date_updated":"2023-01-18T10:08:08Z","publisher":"Association for Computing Machinery","date_created":"2022-10-20T12:58:12Z","author":[{"orcid":"https://orcid.org/0000-0002-4881-5378","last_name":"Soyka","full_name":"Soyka, Chantal","id":"83964","first_name":"Chantal"},{"first_name":"Niclas","full_name":"Schaper, Niclas","last_name":"Schaper"},{"first_name":"Elena","last_name":"Bender","full_name":"Bender, Elena"},{"full_name":"Striewe, Michael","last_name":"Striewe","first_name":"Michael"},{"first_name":"Meike","last_name":"Ullrich","full_name":"Ullrich, Meike"}],"volume":23,"title":"Toward a Competence Model for Graphical Modeling","doi":"10.1145/3567598","publication_status":"published","quality_controlled":"1","issue":"1","year":"2022","citation":{"ama":"Soyka C, Schaper N, Bender E, Striewe M, Ullrich M.

However, developing such business models is a continuous challenging activity where different tasks need to be performed, and business decisions need to be made. Both have to fit the constantly changeable situation in which the business model is developed to reduce the risk of developing ineffective business models with low market penetration. Therefore, a method for developing situation-specific business models is needed. As a solution, we refine the concept of situational method engineering (SME) to business model development. SME, in turn, provides means to construct situation-specific development methods out of fragments from a method repository.\r\n\r\nWe develop a concept for the continuous situation-specific development of business models based on design science. The approach uses the roles of a domain expert, a method engineer, and a business developer together with a repository with method fragments for developing business models and a repository with modeling artifacts for supporting the development. Both repositories are filled by utilizing the experience of domain experts. Out of these repositories, situation-specific development methods for developing business models can be continuously composed based on the changeable situation by the method engineer and enacted by the business developer. We implement it as an open-source tool and evaluate its applicability in an industrial case study of developing a business model for a local event platform. Our results show that situation awareness supports the continuous development of business models.","lang":"eng"}],"department":[{"_id":"66"},{"_id":"534"}],"user_id":"8447","_id":"32307","project":[{"_id":"1","name":"SFB 901: SFB 901"},{"name":"SFB 901 - C: SFB 901 - Project Area C","_id":"4"},{"_id":"17","name":"SFB 901 - C5: SFB 901 - Subproject C5"}],"language":[{"iso":"eng"}],"keyword":["Business Model Development","Situational Method Engineering","Situation-specific","Business Model Canvas","Continuous Development"]},{"year":"2022","quality_controlled":"1","issue":"8","title":"Evaluation eines digitalen Fachspezifischen Chinesischsprachkurses für Studierende des Ingenieurwesens","publisher":"wbv Publikation","date_created":"2023-04-06T09:59:20Z","abstract":[{"text":"Ziel dieser Studie ist es den digitalen moodlegestützten asynchronen Sprachkurs Fachspezifisches Chinesisch für das „Maschinenbau in China Programm“ (mb-cn) der Fakultät für Maschinenbau der Universität Paderborn zu evaluieren, um Handlungsempfehlungen für zukünftig ähnlich aufgebaute Projekte zu entwickeln.

Diagnostic reasoning is understood as iterative exploration of medical evidence. This exploration is represented as a partially observable Markov decision process where the state (i.e., the correct diagnosis) is uncertain. Observation likelihoods and belief updates are computed using a Bayesian network which defines the interrelation between medical risk factors, diagnoses and potential findings. The decision problem is solved via partially observable upper confidence bounds for trees in Monte-Carlo planning. We compute a biased diagnostic exploration policy by altering the generated state transition, observation and reward during look ahead simulations. The resulting diagnostic policies reproduce reasoning errors which have only been described informally in the medical literature. We plan to use this formal representation in the future to inversely detect and classify biased reasoning in actual diagnostic trajectories obtained from physicians."}],"publication":"Proceedings of the 8th Workshop on Formal and Cognitive Reasoning"},{"quality_controlled":"1","year":"2022","citation":{"ama":"Götte R-S, Timmermann J.

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.","lang":"eng"}],"date_created":"2022-02-09T12:50:25Z","author":[{"last_name":"Hesse","id":"29222","full_name":"Hesse, Michael","first_name":"Michael"},{"first_name":"Matthias","full_name":"Hunstig, Matthias","last_name":"Hunstig"},{"first_name":"Julia","id":"15402","full_name":"Timmermann, Julia","last_name":"Timmermann"},{"id":"552","full_name":"Trächtler, Ansgar","last_name":"Trächtler","first_name":"Ansgar"}],"date_updated":"2024-11-13T08:44:17Z","conference":{"name":"11th International Conference on Pattern Recognition Applications and Methods","start_date":"2022-02-03","end_date":"2022-02-05","location":"Online"},"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":{"chicago":"Hesse, Michael, Matthias Hunstig, Julia Timmermann, and Ansgar Trächtler. “Batch Constrained Bayesian Optimization for UltrasonicWire Bonding Feed-Forward Control Design.” In Proceedings of the 11th International Conference on Pattern Recognition Applications and Methods (ICPRAM), 383–94, 2022.","ieee":"M.

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"}],"user_id":"55557","department":[{"_id":"79"}],"_id":"25126","language":[{"iso":"eng"}],"file_date_updated":"2021-09-29T12:34:47Z","ddc":["000"],"keyword":["Robot Exploration","Finite Automaton","Hybrid Model for Programmable Matter","Convex Hull"]},{"title":"Situation-specific Business Model Development Methods for Mobile App Developers","doi":"10.1007/978-3-030-79186-5_17","oa":"1","date_updated":"2022-01-06T06:55:08Z","publisher":"Springer","date_created":"2021-04-20T13:23:41Z","author":[{"first_name":"Sebastian","full_name":"Gottschalk, Sebastian","id":"47208","last_name":"Gottschalk"},{"id":"8447","full_name":"Yigitbas, Enes","last_name":"Yigitbas","orcid":"0000-0002-5967-833X","first_name":"Enes"},{"first_name":"Alexander","last_name":"Nowosad","full_name":"Nowosad, Alexander"},{"first_name":"Gregor","full_name":"Engels, Gregor","last_name":"Engels"}],"year":"2021","citation":{"ieee":"S.
