Existing approaches often utilize impedance measurements over a range of frequencies or velocity measurements and require additional equipment or sensors, such as a laser Doppler vibrometer. Furthermore, the non-negligible effects of varying operating conditions are often unconsidered. To minimize the need for additional sensors while maintaining the dependability of piezoelectric bending actuators irrespective of varying operating conditions, an online diagnostics approach is proposed. To this end, time- and frequency-domain features are extracted from monitored current signals to reflect hairline crack development in bending actuators. For validation of applicability, the presented analysis method was evaluated on piezoelectric bending actuators subjected to accelerated lifetime tests at varying voltage amplitudes and under external damping conditions. In the presence of a crack and due to a diminished stiffness, the resonance frequency decreases and the root-mean-square amplitude of the current signal simultaneously abruptly drops during the lifetime tests. Furthermore, the piezoelectric crack surfaces clapping is reflected in higher harmonics of the current signal. Thus, time-domain features and harmonics of the current signals are sufficient to diagnose hairline cracks in the actuators.","lang":"eng"}],"user_id":"9557","language":[{"iso":"eng"}],"date_updated":"2024-03-15T16:15:56Z","doi":"10.3390/electronics13030521","department":[{"_id":"151"}],"publication_identifier":{"issn":["2079-9292"]},"publication_status":"published","title":"Diagnostics of Piezoelectric Bending Actuators Subjected to Varying Operating Conditions"},{"type":"book_chapter","citation":{"apa":"Goller, M., & Paloniemi, S.

Agency is understood as a multifaceted construct describing the idea that human beings make choices, act on these choices, and thereby exercise influence on their own lives as well as their environment. We argue that the concept is discussed from three different perspectives in the literature—transformational, dispositional, and relational—that are each related to learning and development in work contexts. These perspectives do not reflect incompatible positions but rather different aspects of the same phenomena. The chapter also offers an avenue of insight into empirical studies that employ agency as a central concept as well as discussions about concepts that closely overlap with ideas of human beings as agents of power and influence.","lang":"eng"}],"user_id":"50788","language":[{"iso":"eng"}],"date_updated":"2022-03-13T19:14:43Z","doi":"10.1007/978-3-030-89582-2_1","department":[{"_id":"452"}],"publication_identifier":{"issn":["2210-5549","2210-5557"],"isbn":["9783030895815","9783030895822"]},"publication_status":"published","place":"Cham","title":"Agency: Taking Stock of Workplace Learning Research","related_material":{"link":[{"url":"https://link.springer.com/chapter/10.1007/978-3-030-89582-2_1#Abs1","relation":"other"}]}},{"date_updated":"2022-03-13T19:14:38Z","doi":"10.1007/978-3-030-89582-2_19","language":[{"iso":"eng"}],"place":"Cham","related_material":{"link":[{"url":"https://link.springer.com/chapter/10.1007/978-3-030-89582-2_19#citeas","relation":"other"}]},"title":"Research on Workplace Learning in Times of Digitalisation","department":[{"_id":"452"}],"publication_identifier":{"isbn":["9783030895815","9783030895822"],"issn":["2210-5549","2210-5557"]},"publication_status":"published","_id":"30290","type":"book_chapter","year":"2022","citation":{"mla":"Harteis, Christian. “Research on Workplace Learning in Times of Digitalisation.” Research Approaches on Workplace Learning, Springer International Publishing, 2022, doi:10.1007/978-3-030-89582-2_19.","bibtex":"@inbook{Harteis_2022, place={Cham}, title={Research on Workplace Learning in Times of Digitalisation}, DOI={10.1007/978-3-030-89582-2_19}, booktitle={Research Approaches on Workplace Learning}, publisher={Springer International Publishing}, author={Harteis, Christian}, year={2022} }","ama":"Harteis C.

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.","lang":"eng"}],"year":"2022","type":"conference","citation":{"bibtex":"@inproceedings{Gottschalk_Yigitbas_Engels_2022, title={Model-driven Continuous Experimentation on Component-based Software Architectures }, DOI={10.1109/ICSA-C54293.2022.00011}, booktitle={Proceedings of the 18th International Conference on Software Architecture Companion }, publisher={IEEE}, author={Gottschalk, Sebastian and Yigitbas, Enes and Engels, Gregor}, year={2022} }","mla":"Gottschalk, Sebastian, et al. “Model-Driven Continuous Experimentation on Component-Based Software Architectures .” Proceedings of the 18th International Conference on Software Architecture Companion , IEEE, 2022, doi:10.1109/ICSA-C54293.2022.00011.","ama":"Gottschalk S, Yigitbas E, Engels G.

In doing so, both the knowledge of the educational sciences and the development of competence self-assessments in the fields of teaching, education, assessment andinnovating are taken into account. The study makes use of the following individual requirements: age, sex, Abitur grade, Bachelor grade, Confession. In order to be able to discuss the re-sults regarding their importance for the professionalization of prospective teachers, the importance of knowledge for professional skills is highlighted, preceded by empirical findings. Subsequently, hypotheses are derived, the plan of the study as well as the test instruments are presented, the results presented and discussed. The results show that the Abitur and Bachelor grades clarify the variance in pedagogical knowledge, that there is a significant development in the competence self-assessments of prospective teachers, and that prospective religious teachers are not different from other students. The discussion takes into account, among other things, the ideas for the devel-opment of professional skills and identifies limitations associated with the study. This is followed by the formula-tion of an outlook.

The common understanding of inclusion as a process geared towards equal participation of all children (Booth, 2012) requires a reflexive questioning of established values, attitudes and practices in order to develop inclusive subject related research, teacher training and teaching and learning (Pech & Schomaker, 2013). Among other things, this results in consequences for the design of pre- service teacher training. To a large extent, teacher education is driven by the promotion of central competencies, interests and self-efficacy (Baumert & Kunter, 2011). It aims towards the development and realisation of inclusive interdisciplinary science and social studies (‘Sachunterricht’) in primary education (Moser, 2018). In conjunction with largely acknowledged constructivist approaches to teaching and learning (Möller, 2001), the development of personality, the consideration of basic needs (Deci & Ryan, 1993) and promotion of individual potentials are repeatedly fundamentally represented in subject related and pedagogical considerations (Feuser, 1989; GDSU, 2013). Therefore, the aforementioned constructivist approach is connected to several certain key paradigms for teaching and learning processes (e.g., Vygotskij, 1978; Posner et al., 1982; van de Pol et al., 2010). In this regard, the nature of primary school students’ basic needs have empirically not been sufficiently studied yet. Theoretical frameworks from motivational psychology (Deci & Ryan, 1993) do not explicitly address how individual needs differ and how the diversity of needs can be included in joint-learning, multi-perspective technology education classes. The research project the present paper is part of aims to develop a research-based concept for the professionalisation of pre-service teachers in a seminar course. Therefore, the promotion of the pre- service teachers’ interests and self-efficacy expectations have been assessed in a pre-post research design with a control group visiting another course not related to technology education and inclusion. The present paper describes and discusses first results of the project and will give an outlook on subsequent developmental tasks."}],"status":"public","date_created":"2023-01-25T15:13:45Z","author":[{"first_name":"Franz","full_name":"Schröer, Franz","last_name":"Schröer","id":"71764"},{"first_name":"Claudia","full_name":"Tenberge, Claudia","last_name":"Tenberge","id":"67302"}],"quality_controlled":"1","publication":"PATT39 - PATT on the Edge Technology, Innovation and Education","keyword":["Inclusion","basic needs","pre-service teacher training","interest","self-efficacy"],"_id":"40046","conference":{"location":"St. John’s, Newfoundland and Labrador, Canada","name":"PATT39 - PATT on the Edge Technology, Innovation and Education","start_date":"2022-06-21","end_date":"2022-06-24"},"year":"2022","type":"conference","citation":{"bibtex":"@inproceedings{Schröer_Tenberge_2022, place={St. John’s, Newfoundland and Labrador, Canada}, series={PATT Proceedings}, title={How to enable pre-service teachers to design technological teaching and learning inclusively? – On the nature and consideration of basic needs in teacher training}, booktitle={PATT39 - PATT on the Edge Technology, Innovation and Education}, author={Schröer, Franz and Tenberge, Claudia}, editor={Gill, David and Tuff, Jim and Kennedy, Thomas and Pendergast, Shawn and Jamil, Sana}, year={2022}, pages={49–57}, collection={PATT Proceedings} }","mla":"Schröer, Franz, and Claudia Tenberge. “How to Enable Pre-Service Teachers to Design Technological Teaching and Learning Inclusively? – On the Nature and Consideration of Basic Needs in Teacher Training.” PATT39 - PATT on the Edge Technology, Innovation and Education, edited by David Gill et al., 2022, pp. 49–57.","chicago":"Schröer, Franz, and Claudia Tenberge. “How to Enable Pre-Service Teachers to Design Technological Teaching and Learning Inclusively? – On the Nature and Consideration of Basic Needs in Teacher Training.” In PATT39 - PATT on the Edge Technology, Innovation and Education, edited by David Gill, Jim Tuff, Thomas Kennedy, Shawn Pendergast, and Sana Jamil, 49–57.

Yet there is little information about the impact of family climate on adolescents’ social adaptation, and the term “family climate” is seldom clearly defined and is usually related to other concepts, such as family systems or family environments. To understand the core of family climate, this study conducted a systematic review to analyze research about family climate associated with adolescents’ social adaptation in community samples. A search of empirical research published over the last 20 years identified 12 relevant studies. The studies revealed that family climate can mainly be described in terms of cohesion, conflict, organization, adaptability, and expressiveness. Family climate was shown to be a good predictor of both problem-solving skills and violence in relationships and exhibited further associations with other aspects of social adaptation. This review revealed a need for more systematic and longitudinal research on family climate in community samples."}]},{"title":"Self-Learning Multi-Objective Service Coordination Using Deep Reinforcement Learning","project":[{"name":"SFB 901","_id":"1"},{"name":"SFB 901 - Project Area C","_id":"4"},{"name":"SFB 901 - Subproject C4","_id":"16"}],"department":[{"_id":"75"}],"oa":"1","doi":"10.1109/TNSM.2021.3076503","date_updated":"2022-01-06T06:55:15Z","language":[{"iso":"eng"}],"user_id":"35343","ddc":["000"],"article_type":"original","abstract":[{"text":"Modern services consist of interconnected components,e.g., microservices in a service mesh or machine learning functions in a pipeline. These services can scale and run across multiple network nodes on demand. To process incoming traffic, service components have to be instantiated and traffic assigned to these instances, taking capacities, changing demands, and Quality of Service (QoS) requirements into account. This challenge is usually solved with custom approaches designed by experts. While this typically works well for the considered scenario, the models often rely on unrealistic assumptions or on knowledge that is not available in practice (e.g., a priori knowledge).\r\n\r\nWe propose DeepCoord, a novel deep reinforcement learning approach that learns how to best coordinate services and is geared towards realistic assumptions. It interacts with the network and relies on available, possibly delayed monitoring information. Rather than defining a complex model or an algorithm on how to achieve an objective, our model-free approach adapts to various objectives and traffic patterns. An agent is trained offline without expert knowledge and then applied online with minimal overhead. Compared to a state-of-the-art heuristic, DeepCoord significantly improves flow throughput (up to 76%) and overall network utility (more than 2x) on realworld network topologies and traffic traces. It also supports optimizing multiple, possibly competing objectives, learns to respect QoS requirements, generalizes to scenarios with unseen, stochastic traffic, and scales to large real-world networks. For reproducibility and reuse, our code is publicly available.","lang":"eng"}],"has_accepted_license":"1","status":"public","date_created":"2021-04-27T08:04:16Z","file":[{"access_level":"open_access","file_name":"ris-accepted-version.pdf","date_created":"2021-04-27T08:01:26Z","date_updated":"2021-04-27T08:01:26Z","content_type":"application/pdf","relation":"main_file","description":"Author version of the accepted paper","file_size":4172270,"creator":"stschn","file_id":"21809"}],"author":[{"orcid":"0000-0001-8210-4011","full_name":"Schneider, Stefan Balthasar","first_name":"Stefan Balthasar","id":"35343","last_name":"Schneider"},{"first_name":"Ramin","full_name":"Khalili, Ramin","last_name":"Khalili"},{"full_name":"Manzoor, Adnan","first_name":"Adnan","last_name":"Manzoor"},{"last_name":"Qarawlus","full_name":"Qarawlus, Haydar","first_name":"Haydar"},{"last_name":"Schellenberg","first_name":"Rafael","full_name":"Schellenberg, Rafael"},{"id":"126","last_name":"Karl","full_name":"Karl, Holger","first_name":"Holger"},{"last_name":"Hecker","first_name":"Artur","full_name":"Hecker, Artur"}],"publisher":"IEEE","file_date_updated":"2021-04-27T08:01:26Z","publication":"Transactions on Network and Service Management","keyword":["network management","service management","coordination","reinforcement learning","self-learning","self-adaptation","multi-objective"],"_id":"21808","year":"2021","citation":{"ieee":"S.

Existing approaches often require strict assumptions about or perfect knowledge of the underlying radio system, its resource allocation scheme, or user movements, none of which is readily available in practice.\r\n\r\nInstead, we propose three novel self-learning and self-adapting approaches using model-free deep reinforcement learning (DRL): DeepCoMP, DD-CoMP, and D3-CoMP. DeepCoMP leverages central observations and control of all users to select cells almost optimally. DD-CoMP and D3-CoMP use multi-agent DRL, which allows distributed, robust, and highly scalable coordination. All three approaches learn from experience and self-adapt to varying scenarios, reaching 2x higher Quality of Experience than other approaches. They have very few built-in assumptions and do not need prior system knowledge, making them more robust to change and better applicable in practice than existing approaches.","lang":"eng"}]},{"intvolume":" 25","_id":"32558","issue":"2","main_file_link":[{"open_access":"1","url":"https://link.springer.com/content/pdf/10.1007/s10984-021-09377-8.pdf"}],"year":"2021","type":"journal_article","citation":{"mla":"Bonanati, Sabrina, and Heike M.

Schools, peers, and home learning environments are important sources for the development of positive self-efficacy. Expanding on previous research, we investigated the associations between different aspects of the digital home learning environment and students’ ICT self-efficacy. The moderation effects of gender were also tested. A total of 651 children answered a questionnaire about different digital home learning environment dimensions and estimated their ICT self-efficacy using an adapted scale—Schwarzer and Jerusalem’s (1999) general self-efficacy scale. Using the structural equation modeling technique, a digital home learning environment containing six different qualities of parental support was investigated. Families’ cultural capital, parents’ attitudes toward the Internet, and shared Internet activities at home contributed positively to ICT self-efficacy. We observed small gender differences, with the moderation effect being nonsignificant. The results help researchers and practitioners to understand how different dimensions of the digital home learning environment support ICT self-efficacy. We will discuss how parents can enhance the home learning environment and how teachers can integrate this knowledge into formal education."}],"user_id":"42165","publisher":"Springer Science and Business Media LLC","author":[{"full_name":"Bonanati, Sabrina","first_name":"Sabrina","last_name":"Bonanati"},{"first_name":"Heike M.","full_name":"Buhl, Heike M.","last_name":"Buhl","id":"27152"}],"keyword":["Digital media use","Gender","Home learning environment","ICT self-efcacy","Motivation","Parental involvement"],"publication":"Learning Environments Research","volume":25,"status":"public","date_created":"2022-08-03T05:53:48Z","date_updated":"2022-08-29T06:36:37Z","doi":"10.1007/s10984-021-09377-8","oa":"1","language":[{"iso":"eng"}],"title":"The digital home learning environment and its relation to children’s ICT self-efficacy","department":[{"_id":"427"}],"publication_identifier":{"issn":["1387-1579","1573-1855"]},"publication_status":"published"},{"_id":"37136","date_updated":"2023-01-18T13:40:40Z","language":[{"iso":"eng"}],"type":"working_paper","citation":{"chicago":"Ichev, Riste, Jernej Koren, Urska Kosi, Katarina Sitar Sustar, and Aljosa Valentincic.

We use a sample of 4,058 small private firms operating in the period 2006‐2017 that are not subject to mandatory audits. Firms decide for a voluntary audit of financial statements either because the economic setting in which they operate effectively forces them to do so (e.g., ownership complexity, export‐oriented supply chain, subsidiary status) or because firm fundamentals and/or financial reporting practices limit their access to financial debt, both reflected in earnings quality. We use these factors to model the decision for voluntary audit. In the outcome analyses, we find robust evidence that voluntary audits are associated with higher, rather than lower, interest rate by up to 3.0 percentage points. This effect is present regardless of the perceived audit quality (Big‐4 vs. non‐Big‐4), but is stronger for non‐Big‐4 audits where auditees have a stronger position relative to auditors. Audited firms’ earnings are less informative about future operating performance relative to unaudited counterparts. We conclude that voluntary audits facilitate access to financial debt for firms with higher risk that may otherwise have no access to this form of financing. The price paid is reflected in higher interest rates charged to firms with voluntary audits – firms with higher information and/or fundamental risk.","lang":"eng"}],"date_created":"2023-01-17T15:03:08Z","status":"public","department":[{"_id":"635"},{"_id":"186"},{"_id":"551"}],"keyword":["private firms","voluntary audit","cost of debt","self‐selection bias","risk"],"author":[{"last_name":"Ichev","first_name":"Riste","full_name":"Ichev, Riste"},{"full_name":"Koren, Jernej","first_name":"Jernej","last_name":"Koren"},{"first_name":"Urska","full_name":"Kosi, Urska","last_name":"Kosi","id":"54068"},{"full_name":"Sitar Sustar, Katarina","first_name":"Katarina","last_name":"Sitar Sustar"},{"full_name":"Valentincic, Aljosa","first_name":"Aljosa","last_name":"Valentincic"}]},{"author":[{"first_name":"Benedikt","full_name":"Uhe, Benedikt","last_name":"Uhe","id":"38131"},{"last_name":"Kuball","full_name":"Kuball, Clara-Maria","first_name":"Clara-Maria"},{"last_name":"Merklein","first_name":"Marion","full_name":"Merklein, Marion"},{"first_name":"Gerson","orcid":"0000-0002-2763-1246","full_name":"Meschut, Gerson","last_name":"Meschut","id":"32056"}],"publisher":"Springer","quality_controlled":"1","keyword":["Self-piercing riveting","Lightweight design","Deformation behaviour","Stainless steel","High nitrogen steel"],"publication":"Forming the Future - Proceedings of the 13th International Conference on the Technology of Plasticity.

The focus of the present investigation is on the evaluation of the influences of the rivet’s geometry and material on its deformation behaviour. Conventional rivets of types P and HD2, a rivet with an improved geometry made of treatable steel 38B2, and rivets made of the stainless steels 1.3815 and 1.4541 are examined. The analysis is conducted by means of multi-step joining tests for two material combinations comprising high-strength steel HCT70X and aluminium EN AW-5083. The joints are cut to provide a cross-section and the deformation behaviour of the different rivets is analysed on the basis of the measured changes in geometry and hardness. In parallel, an examination of the force-stroke curves provides further insights. It can be demonstrated that, besides the geometry, the material strength, in particular, has a significant influence on the deformation behaviour of the rivet. The strength of steel 1.4541 is seen to be too low for the joining task, while the strength of steel 1.3815 is sufficient, and hence the investigation confirms the capability of rivets made of 1.3815 for joining even challenging material combinations.","lang":"eng"}],"user_id":"38131","citation":{"ieee":"B.

Conventional rivets for self-piercing riveting differ in their geometry, the material used, the condition of the material and the coating. To shorten the manufacturing process, the use of stainless steel with high strain hardening as the rivet material represents a promising approach. This allows the coating of the rivets to be omitted due to the corrosion resistance of the material and, since the strength of the stainless steel is achieved by cold forming, heat treatment is no longer required. In addition, it is possible to adjust the local strength within the rivet. Because of that, the authors have elaborated a concept for using high nitrogen steel 1.3815 as the rivet material. The present investigation focusses on the joint strength in order to evaluate the capability of rivets in high nitrogen steel by comparison to conventional rivets made of treatable steel. Due to certain challenges in the forming process of the high nitrogen steel rivets, deviations result from the targeted rivet geometry. Mainly these deviations cause a lower joint strength with these rivets, which is, however, adequate. All in all, the capability of the new rivet is proven by the results of this investigation.

As a consequence of the resulting need for multi-material design, mechanical joining technologies become increasingly important. Mechanical joining allows for the combination of dissimilar materials, while thermic joining techniques reach their limits. Self-piercing riveting enables the joining of dissimilar materials by using semi-tubular rivets as mechanical fasteners. The rivet production, however, is costly and time-consuming, as the rivets generally have to be hardened, tempered and coated after forming, in order to achieve an adequate strength and corrosion resistance. A promising approach to improve the efficiency of the rivet manufacturing is the use of high-strength high nitrogen steel as rivet material because these additional process steps would not be necessary anymore. As a result of the comparatively high nitrogen content, such steels have various beneficial properties like higher strength, good ductility and improved corrosion resistance. By cold bulk forming of high nitrogen steels high-strength parts can be manufactured due to the strengthening which is caused by the high strain hardening. However, high tool loads thereby have to be expected and are a major challenge during the production process. Consequently, there is a need for appropriate forming strategies. This paper presents key aspects concerning the process design for the manufacturing of semi-tubular self-piercing rivets made of high-strength steel. The aim is to produce the rivets in several forming stages without intermediate heat treatment between the single stages. Due to the high strain hardening of the material, a two stage forming concept will be investigated. Cup-backward extrusion is chosen as the first process step in order to form the rivet shank without forming the rivet foot. Thus, the strain hardening effects in the area of the rivet foot are minimized and the tool loads during the following process step can be reduced. During the second and final forming stage the detailed geometry of the rivet foot and the rivet head is formed. In this context, the effect of different variations, for example concerning the final geometry of the rivet foot, on the tool load is investigated using multistage numerical analysis. Furthermore, the influence of the process temperature on occurring stresses is analysed. Based on the results of the investigations, an adequate forming strategy and a tool concept for the manufacturing of semi-tubular self-piercing rivets made of high-strength steel are presented."}],"user_id":"38131","quality_controlled":"1","keyword":["high nitrogen steel","self-piercing riveting","joining by forming","bulk forming","tool design"],"volume":50,"status":"public","date_created":"2020-10-12T08:30:08Z"},{"conference":{"name":"8th International Working Conference on Human-Centered Software Engineering (HCSE'20)","start_date":"2020-11-30","location":"Eindhoven","end_date":"2020-12-02"},"_id":"18249","intvolume":" 12481","type":"conference","citation":{"short":"S.

Here, the developers of the apps focus on the positioning of atomic 3D objects in the physical environment. With this focus, they neglect the configuration of multi-faceted 3D object composition according to the user needs and environmental constraints. To tackle these challenges, we present a model-based approach to support AR-assisted product con-figuration based on the concept of Dynamic Software Product Lines. Our approach splits products (e.g. table) into parts (e.g. tabletop, ta-ble legs, funnier) with their 3D objects and additional information (e.g. name, price). The possible products, which can be configured out of these parts, are stored in a feature model. At runtime, this feature model can be used to configure 3D object compositions out of the product parts and adapt to user needs and environmental constraints. The benefits of this approach are demonstrated by a case study of configuring modular kitchens with the help of a prototypical mobile-based implementation."}],"ddc":["000"],"user_id":"47208","file_date_updated":"2020-11-30T08:36:52Z","keyword":["Product Configuration","Augmented Reality","Runtime Adaptation","Dynamic Software Product Lines"],"publication":"Human-Centered Software Engineering.

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"}],"has_accepted_license":"1","status":"public","date_created":"2020-05-04T12:16:54Z","publisher":"IEEE","author":[{"id":"47208","last_name":"Gottschalk","full_name":"Gottschalk, Sebastian","first_name":"Sebastian"},{"id":"5281","last_name":"Rittmeier","full_name":"Rittmeier, Florian","first_name":"Florian"},{"last_name":"Engels","id":"107","first_name":"Gregor","full_name":"Engels, Gregor"}],"keyword":["Business Model Decision Line","Business Model Adaptation","Hypothesis-driven Adaptation","Software Product Line","Feature Model"],"file_date_updated":"2020-07-14T09:33:00Z","publication":"Proceedings of the 22nd IEEE International Conference on Business Informatics","file":[{"file_size":569290,"file_id":"17383","creator":"sego","date_updated":"2020-07-14T09:33:00Z","content_type":"application/pdf","relation":"main_file","date_created":"2020-07-14T09:33:00Z","file_name":"CBI.pdf","access_level":"open_access"}],"_id":"16933","conference":{"end_date":"2020-06-24","location":"Antwerp","name":"22nd IEEE International Conference on Business Informatics","start_date":"2020-06-22"},"citation":{"ieee":"S.
