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"}],"date_created":"2020-05-04T12:16:54Z","status":"public","has_accepted_license":"1","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","publisher":"IEEE","author":[{"full_name":"Gottschalk, Sebastian","first_name":"Sebastian","id":"47208","last_name":"Gottschalk"},{"last_name":"Rittmeier","id":"5281","first_name":"Florian","full_name":"Rittmeier, Florian"},{"last_name":"Engels","id":"107","first_name":"Gregor","full_name":"Engels, Gregor"}],"file":[{"file_name":"CBI.pdf","date_created":"2020-07-14T09:33:00Z","access_level":"open_access","file_size":569290,"file_id":"17383","creator":"sego","content_type":"application/pdf","date_updated":"2020-07-14T09:33:00Z","relation":"main_file"}]},{"_id":"16934","intvolume":" 391","conference":{"end_date":"2020-07-08","location":"Potsdam","name":"10th International Symposium on Business Modeling and Software Design ","start_date":"2020-07-06"},"type":"conference","year":"2020","citation":{"short":"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.

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"}],"user_id":"61579","title":"Distinguishing Knowledge Impact from Citation Impact: A Methodology for Analysing Knowledge Impact for the Literature Review Genre","ddc":["000"]},{"language":[{"iso":"eng"}],"date_updated":"2022-01-06T06:53:03Z","oa":"1","department":[{"_id":"277"}],"title":"Designing a Novel Strategy for Exploring Literature Corpora","citation":{"ieee":"G.

Nevertheless, corresponding guidelines have not been updated for decades. We contend that the traditional strategy of skimming all papers and reading selected papers afterwards needs to be revised. Therefore, we design a new strategy that guides the overall exploratory process by prioritizing influential papers for initial reading, followed by skimming the remaining papers. Consistent with schemata theory, starting with in-depth reading allows readers to acquire more substantial prior content schemata, which are representa-tive for the literature corpus and useful in the following skimming process. To this end, we develop a prototype that identifies the influential papers from a set of PDFs, which is illustrated in a case study in the IT business value domain. With the new strategy, we envision a more efficient process of exploring unknown literature corpora.","lang":"eng"}],"ddc":["000"],"user_id":"61579"},{"main_file_link":[{"url":"https://www.ama-science.org/proceedings/getFile/Zmp0ZN==","open_access":"1"}],"type":"conference","year":"2020","citation":{"chicago":"Dreiling, Dmitrij, Dominik Thor Itner, Nadine Feldmann, Hauke Gravenkamp, and Bernd Henning. “Increasing the Sensitivity in the Determination of Material Parameters by Using Arbitrary Loads in Ultrasonic Transmission Measurements.” AMA Service GmbH, 2020. https://doi.org/10.5162/SMSI2020/D1.3.","apa":"Dreiling, D., Itner, D.

However, plasmonic metasurfaces show some severe limitation for nonlinear frequency conversion due to the intrinsic high ohmic loss and low damage threshold of plasmonic nanostructures. Here, the nonlinear geometric‐phases associated with the third‐harmonic generation process occurring in all‐dielectric metasurfaces is studied systematically, which are composed of silicon nanofins with different in‐plane rotational symmetries. It is found that the wave coupling among different field components of the resonant fundamental field gives rise to the appearance of different nonlinear geometric‐phases of the generated third‐harmonic signals. The experimental observations of the nonlinear beam steering and nonlinear holography realized in this work by all‐dielectric geometric‐phase metasurfaces are well explained with the developed theory. This work offers a new physical picture to understand the nonlinear optical process occurring at nanoscale dielectric resonators and will help in the design of nonlinear metasurfaces with tailored phase properties.","lang":"eng"}],"user_id":"30525","ddc":["530"],"file":[{"date_created":"2020-02-28T17:37:38Z","file_name":"adom.201902050.pdf","access_level":"closed","creator":"zentgraf","file_id":"16202","file_size":2914923,"success":1,"relation":"main_file","content_type":"application/pdf","date_updated":"2020-02-28T17:37:38Z"}],"author":[{"last_name":"Liu","full_name":"Liu, Bingyi","first_name":"Bingyi"},{"first_name":"Basudeb","full_name":"Sain, Basudeb","last_name":"Sain"},{"last_name":"Reineke","first_name":"Bernhard","full_name":"Reineke, Bernhard"},{"last_name":"Zhao","first_name":"Ruizhe","full_name":"Zhao, Ruizhe"},{"id":"20798","last_name":"Meier","orcid":"https://orcid.org/0000-0002-3787-3572","full_name":"Meier, Cedrik","first_name":"Cedrik"},{"first_name":"Lingling","full_name":"Huang, Lingling","last_name":"Huang"},{"full_name":"Jiang, Yongyuan","first_name":"Yongyuan","last_name":"Jiang"},{"last_name":"Zentgraf","id":"30525","first_name":"Thomas","full_name":"Zentgraf, Thomas","orcid":"0000-0002-8662-1101"}],"publisher":"Wiley","quality_controlled":"1","file_date_updated":"2020-02-28T17:37:38Z","publication":"Advanced Optical Materials","status":"public","has_accepted_license":"1","date_created":"2020-02-28T17:29:17Z","volume":8,"_id":"16197","intvolume":" 8","issue":"9","article_number":"1902050","main_file_link":[{"url":"https://onlinelibrary.wiley.com/doi/full/10.1002/adom.201902050","open_access":"1"}],"type":"journal_article","year":"2020","citation":{"ieee":"B.

To dynamically adjust to everchanging\r\ntraffic demands, VNFs have to be instantiated and\r\ntheir allocated resources have to be adjusted on demand.\r\nDeciding the amount of allocated resources is non-trivial.\r\nExisting optimization approaches often assume fixed resource\r\nrequirements for each VNF instance. However, this can easily\r\nlead to either waste of resources or bad service quality if too\r\nmany or too few resources are allocated.\r\n\r\nTo solve this problem, we train machine learning models\r\non real VNF data, containing measurements of performance\r\nand resource requirements. For each VNF, the trained models\r\ncan then accurately predict the required resources to handle\r\na certain traffic load. We integrate these machine learning\r\nmodels into an algorithm for joint VNF scaling and placement\r\nand evaluate their impact on resulting VNF placements. Our\r\nevaluation based on real-world data shows that using suitable\r\nmachine learning models effectively avoids over- and underallocation\r\nof resources, leading to up to 12 times lower resource\r\nconsumption and better service quality with up to 4.5 times\r\nlower total delay than using standard fixed resource allocation."}],"user_id":"35343","ddc":["000"],"file":[{"relation":"main_file","content_type":"application/pdf","date_updated":"2020-03-03T11:42:16Z","file_id":"16220","creator":"stschn","file_size":476590,"access_level":"open_access","file_name":"ris_preprint.pdf","date_created":"2020-03-03T11:42:16Z"}],"file_date_updated":"2020-03-03T11:42:16Z","publication":"IEEE Conference on Network Softwarization (NetSoft)","publisher":"IEEE","author":[{"first_name":"Stefan Balthasar","full_name":"Schneider, Stefan Balthasar","orcid":"0000-0001-8210-4011","last_name":"Schneider","id":"35343"},{"last_name":"Satheeschandran","full_name":"Satheeschandran, Narayanan Puthenpurayil","first_name":"Narayanan Puthenpurayil"},{"first_name":"Manuel","full_name":"Peuster, Manuel","last_name":"Peuster","id":"13271"},{"last_name":"Karl","id":"126","first_name":"Holger","full_name":"Karl, Holger"}],"date_created":"2020-03-03T11:42:22Z","status":"public","has_accepted_license":"1","conference":{"location":"Ghent, Belgium","name":"IEEE Conference on Network Softwarization (NetSoft)"},"_id":"16219","type":"conference","year":"2020","citation":{"bibtex":"@inproceedings{Schneider_Satheeschandran_Peuster_Karl_2020, title={Machine Learning for Dynamic Resource Allocation in Network Function Virtualization}, booktitle={IEEE Conference on Network Softwarization (NetSoft)}, publisher={IEEE}, author={Schneider, Stefan Balthasar and Satheeschandran, Narayanan Puthenpurayil and Peuster, Manuel and Karl, Holger}, year={2020} }","mla":"Schneider, Stefan Balthasar, et al. “Machine Learning for Dynamic Resource Allocation in Network Function Virtualization.” IEEE Conference on Network Softwarization (NetSoft), IEEE, 2020.","apa":"Schneider, S.

We regard timing in two dimensions, namely the time of announcement in relation to the time of investment and the time of announcement in relation to the time of a fundamental security incident. The financial value of information security investments is assessed by examining the relationship between the investment announcements and their stock market reaction focusing on the two time dimensions. Using an event study methodology, we found that both dimensions influence the stock market return of the investing organization. Our results indicate that (1) after fundamental security incidents in a given industry, the stock price will react more positively to a firm’s announcement of actual information security investments than to announcements of the intention to invest; (2) the stock price will react more positively to a firm’s announcements of the intention to invest after the fundamental security incident compared to before; and (3) the stock price will react more positively to a firm’s announcements of actual information security investments after the fundamental security incident compared to before. Overall, the lowest abnormal return can be expected when the intention to invest is announced before a fundamental information security incident and the highest return when actual investing after a fundamental information security incident in the respective industry."}],"language":[{"iso":"eng"}],"oa":"1","date_updated":"2022-01-06T06:52:47Z","department":[{"_id":"277"}],"title":"Timing in Information Security: An Event Study on the Impact of Information Security Investment Announcements"},{"project":[{"_id":"35","grant_number":"02K15A073","name":"Interaktive Einkaufserlebnisse in Innenstädten durch digitale Dienstleistungen"}],"publication_status":"published","department":[{"_id":"526"}],"title":"Designing City Center Area Recommendation Systems ","place":"Potsdam","language":[{"iso":"eng"}],"oa":"1","doi":"doi.org/10.30844/wi_2020_e1-heiden","date_updated":"2022-01-06T06:52:48Z","has_accepted_license":"1","status":"public","date_created":"2020-03-13T07:05:24Z","file":[{"content_type":"application/pdf","date_updated":"2020-03-13T06:58:54Z","relation":"main_file","success":1,"file_size":1370273,"creator":"pzh","file_id":"16286","access_level":"closed","date_created":"2020-03-13T06:58:54Z","file_name":"E1_City_recommendations_Master_final.pdf"}],"quality_controlled":"1","author":[{"first_name":"Philipp","full_name":"zur Heiden, Philipp","last_name":"zur Heiden","id":"64394"},{"first_name":"Carsten Ingo","full_name":"Berendes, Carsten Ingo","last_name":"Berendes","id":"53344"},{"full_name":"Beverungen, Daniel","first_name":"Daniel","id":"59677","last_name":"Beverungen"}],"publication":"Proceedings of the 15th International Conference on Wirtschaftsinformatik","file_date_updated":"2020-03-13T06:58:54Z","keyword":["Town Center Management","High Street Retail","Recommender Systems","Geospatial Recommendations","Design Science Research"],"user_id":"64394","ddc":["000"],"abstract":[{"text":"To decide in which part of town to open stores, high street retailers consult statistical data on customers and cities, but they cannot analyze their customers’ shopping behavior and geospatial features of a city due to missing data. While previous research has proposed recommendation systems and decision aids that address this type of decision problem – including factory location and assortment planning – there currently is no design knowledge available to prescribe the design of city center area recommendation systems (CCARS). We set out to design a software prototype considering local customers’ shopping interests and geospatial data on their shopping trips for retail site selection. With real data on 500 customers and 1,100 shopping trips, we demonstrate and evaluate our IT artifact.

Controlling an unsteady fluid flow is particularly important, as flow control is a key enabler for technologies in energy (e.g., wind, tidal, and combustion), transportation (e.g., planes, trains, and automobiles), security (e.g., tracking airborne contamination), and health (e.g., artificial hearts and artificial respiration). However, the high-dimensional, nonlinear, and multi-scale dynamics make real-time feedback control infeasible. Fortunately, these high- dimensional systems exhibit dominant, low-dimensional patterns of activity that can be exploited for effective control in the sense that knowledge of the entire state of a system is not required. Advances in machine learning have the potential to revolutionize flow control given its ability to extract principled, low-rank feature spaces characterizing such complex systems.We present a novel deep learning modelpredictive control framework that exploits low-rank features of the flow in order to achieve considerable improvements to control performance. Instead of predicting the entire fluid state, we use a recurrent neural network (RNN) to accurately predict the control relevant quantities of the system, which are then embedded into an MPC framework to construct a feedback loop. In order to lower the data requirements and to improve the prediction accuracy and thus the control performance, incoming sensor data are used to update the RNN online. The results are validated using varying fluid flow examples of increasing complexity."}],"status":"public","date_created":"2020-03-13T12:40:09Z","volume":34,"author":[{"first_name":"Katharina","full_name":"Bieker, Katharina","last_name":"Bieker","id":"32829"},{"first_name":"Sebastian","full_name":"Peitz, Sebastian","orcid":"https://orcid.org/0000-0002-3389-793X","last_name":"Peitz","id":"47427"},{"first_name":"Steven L.","full_name":"Brunton, Steven L.","last_name":"Brunton"},{"full_name":"Kutz, J.
