All propellers and rotors are initially twisted beams, showing significant extension-twist coupling and centrifugal twisting. Torsional deformations severely impact aerodynamic performance. This paper presents a novel approach to assess different reasons for torsional deformations. A reduced-order model runs large parameter sweeps with algebraic formulations and numerical solution procedures. Generic beams represent three different propeller types for General Aviation, Commercial Aviation, and Advanced Air Mobility. Simulations include solid and hollow cross-sections made of aluminum, steel, and carbon fiber-reinforced polymer. The investigation shows that centrifugal twisting moments depend on both the elastic and initial twist. The determination of the centrifugal twisting moment solely based on the initial twist suffers from errors exceeding 5\% in some cases. The nonlinear parts of the torsional rigidity do not significantly impact the overall torsional rigidity for the investigated propeller types. The extension-twist coupling related to the initial and elastic twist in combination with tension forces significantly impacts the net cross-sectional torsional loads. While the increase in torsional stiffness due to initial twist contributes to the overall stiffness for General and Commercial Aviation propellers, its contribution to the lift propeller's stiffness is limited. The paper closes with the presentation of approximations for each effect identified as significant. Numerical evaluations are necessary to determine each effect for inhomogeneous cross-sections made of anisotropic material.}, language = {en} } @article{BeckerDelfmannDietrichetal.2016, author = {Becker, J{\"o}rg and Delfmann, Patrick and Dietrich, Hanns-Alexander and Steinhorst, Matthias and Eggert, Mathias}, title = {Business Process Compliance Checking — Applying and Evaluating a Generic Pattern Matching Approach for Conceptual Models in the Financial Sector}, series = {Information Systems Frontiers}, volume = {18}, journal = {Information Systems Frontiers}, number = {2}, publisher = {Springer}, address = {Berlin}, issn = {1572-9419}, doi = {10.1007/s10796-014-9529-y}, pages = {359 -- 405}, year = {2016}, abstract = {Given the strong increase in regulatory requirements for business processes the management of business process compliance becomes a more and more regarded field in IS research. Several methods have been developed to support compliance checking of conceptual models. However, their focus on distinct modeling languages and mostly linear (i.e., predecessor-successor related) compliance rules may hinder widespread adoption and application in practice. Furthermore, hardly any of them has been evaluated in a real-world setting. We address this issue by applying a generic pattern matching approach for conceptual models to business process compliance checking in the financial sector. It consists of a model query language, a search algorithm and a corresponding modelling tool prototype. It is (1) applicable for all graph-based conceptual modeling languages and (2) for different kinds of compliance rules. Furthermore, based on an applicability check, we (3) evaluate the approach in a financial industry project setting against its relevance for decision support of audit and compliance management tasks.}, language = {en} } @inproceedings{Eggert2019, author = {Eggert, Mathias}, title = {Understanding the acceptance of smart home-based insurances}, series = {Proceedings of the 27th European Conference on Information Systems (ECIS), Stockholm \& Uppsala, Sweden, June 8-14, 2019}, booktitle = {Proceedings of the 27th European Conference on Information Systems (ECIS), Stockholm \& Uppsala, Sweden, June 8-14, 2019}, isbn = {978-1-7336325-0-8}, pages = {1 -- 15}, year = {2019}, language = {en} } @inproceedings{RosemannEggertVoigtetal.2012, author = {Rosemann, Michael and Eggert, Mathias and Voigt, Matthias and Beverungen, Daniel}, title = {Leveraging Social Network Data for Analytical CRM Strategies - The Introduction of Social BI.}, series = {ECIS 2012 Proceedings}, booktitle = {ECIS 2012 Proceedings}, pages = {12 S.}, year = {2012}, language = {en} } @article{Weigand1992, author = {Weigand, Christoph}, title = {Economic Machine Adjustment in the Case of Product Screening .E.v.Collani, Ch.

The aim is to create the largest free trade area in the world. The agreement, once entered into force, will oblige EU countries and the U.S. to further liberalize their markets. The negotiations on TTIP include a chapter on Electronic Communications/ Telecommunications. The challenge therein will be securing commitments for market access to Electronic Communications services. At the same time, these commitments must reflect the legitimate need for consumer protection issues. The need to reduce Electronic Communications-related non-tariff barriers to trade between the Parties is due to the fact that these markets are heavily regulated. Without transnational rules as to regulations national governments can abuse these regulations to deter the market entry by new (foreign) suppliers. Thus the free trade agreement TTIP affects in many respects regulatory provisions on and access to Electronic Communications markets. The objective of this paper is therefore to examine to what extend the regulatory principles for Electronic Communications markets envisaged under TTIP will result in trade facilitation and regulatory convergence between the EU and the U.S. As to this question the result of the analysis is that the chapter on Electronic Communications will be an important step towards facilitating trade in Electronic Communications services. At the same time some regulatory convergence will take place, but this convergence will not lead to a (full) harmonization of regulations. Rather the norm, also after TTIP negotiations will have been concluded successfully, will be mutual recognition of different regulatory regimes. Different regulations being the optimal policy response in different market settings will continue to exist. Moreover, it is very unlikely that such regulatory principles for the Electronic Communications sector are a vehicle for a race to the bottom in levels of consumer protection.}, language = {en} } @inproceedings{JarkeGebhardtJacobsetal.1996, author = {Jarke, Matthias and Gebhardt, Michael and Jacobs, Stephan and Nissen, Hans W.}, title = {Conflict analysis across heterogeneous viewpoints: formalization and visualization}, series = {Proceedings of the 29th Annual Hawaii International Conference on System Sciences}, booktitle = {Proceedings of the 29th Annual Hawaii International Conference on System Sciences}, isbn = {0-8186-7324-9}, doi = {10.1109/HICSS.1996.493191}, pages = {199 -- 208}, year = {1996}, language = {en} } @article{BerneckerBoyerGathmann2021, author = {Bernecker, Andreas and Boyer, Pierre C. and Gathmann, Christina}, title = {The Role of Electoral Incentives for Policy Innovation: Evidence from the US Welfare Reform}, series = {American Economic Journal: Economic Policy}, volume = {13}, journal = {American Economic Journal: Economic Policy}, number = {2}, publisher = {American Economic Association}, address = {Nashville, Tenn.}, issn = {1945-774X}, doi = {10.1257/pol.20190690}, pages = {26 -- 57}, year = {2021}, language = {en} } @inproceedings{SchuhGottschalkHoehneetal.2008, author = {Schuh, G{\"u}nther and Gottschalk, Sebastian and H{\"o}hne, Tim and Attig, Philipp}, title = {Further Potentials of Smart Logistics}, series = {Manufacturing Systems and Technologies for the New Frontier}, booktitle = {Manufacturing Systems and Technologies for the New Frontier}, editor = {Mitsuishi, M.}, publisher = {Springer}, address = {London}, isbn = {978-1-84800-267-8}, doi = {10.1007/978-1-84800-267-8_18}, pages = {93 -- 96}, year = {2008}, language = {en} } @inproceedings{SchuhGottschalkNarretal.2007, author = {Schuh, G{\"u}nther and Gottschalk, Sebastian Friedrich and Narr, Claus and H{\"o}hne, Tim}, title = {Adaptive logistics : information management for planning and control of small series assembly}, series = {2nd International Conference on Changeable, Agile, Reconfigurable and Virtual Production (CARV 2007), Toronto, Ontario, Canada, 22-24 July 2007 : Book of Abstracts}, booktitle = {2nd International Conference on Changeable, Agile, Reconfigurable and Virtual Production (CARV 2007), Toronto, Ontario, Canada, 22-24 July 2007 : Book of Abstracts}, editor = {Z{\"a}h, Michael F.}, isbn = {978-0-9783187-0-3}, pages = {212 -- 221}, year = {2007}, language = {en} } @article{SchuhGottschalkHoehne2007, author = {Schuh, G. and Gottschalk, S. and H{\"o}hne, Tim}, title = {High Resolution Production Management}, series = {CIRP Annals}, volume = {56}, journal = {CIRP Annals}, number = {1}, issn = {0007-8506}, doi = {10.1016/j.cirp.2007.05.105}, pages = {439 -- 442}, year = {2007}, language = {en} } @inproceedings{DrummSchmittDoetal.2007, author = {Drumm, Christian and Schmitt, Matthias and Do, Hong-Hai and Rahm, Erhard}, title = {Quickmig: automatic schema matching for data migration projects}, series = {Proceedings of the 2007 ACM Conference on Information and Knowledge Management / CIKM'07, Lisboa, Portugal, Nov. 6 - 10, 2007}, booktitle = {Proceedings of the 2007 ACM Conference on Information and Knowledge Management / CIKM'07, Lisboa, Portugal, Nov. 6 - 10, 2007}, isbn = {978-1-59593-803-9}, doi = {10.1145/1321440.1321458}, pages = {107 -- 116}, year = {2007}, language = {en} } @inproceedings{WeberMarkovicDrumm2007, author = {Weber, Ingo and Markovic, Ivan and Drumm, Christian}, title = {A conceptual framework for composition in business process management}, series = {Business Information Systems : 10th International Conference, BIS 2007, Poznan, Poland, April 25-27, 2007.

While the commonly applied effort measure is based on analyst behaviour for one firm, our measure considers analyst behaviour for all covered firms. Our general effort measure captures additional information about analyst effort and thus can identify accurate forecasts. We emphasise the importance of investigating analyst behaviour in a larger context and argue that analysts who generally devote substantial forecast effort are also likely to devote substantial effort to a specific firm, even if this effort might not be captured by a firm-specific measure. Empirical results reveal that analysts who devote higher general forecast effort issue more accurate forecasts. Additional investigations show that analysts' career prospects improve with higher general forecast effort. Our measure improves on existing methods as it has higher explanatory power regarding differences in forecast accuracy than the commonly applied effort measure. Additionally, it can address research questions that cannot be examined with a firm-specific measure.

I examine corporate governance along three dimensions: financial information quality, ownership structure and board structure. The results suggest that firms with high levels of financial transparency and bonus compensations face lower cost of equity. In addition, block ownership is negatively related to firms' cost of equity when the blockholders are other firms, managers or founding-family members. Consistent with the conjecture that agency costs increase with firm size, I find significant cost of debt effects only in the largest German companies. Here, the creditors demand lower cost of debt from firms with block ownerships held by corporations or banks. My findings demonstrate that a uniform set of governance attributes is unlikely to satisfy suppliers of debt and equity capital equally.}, language = {en} } @incollection{KrollLudwigs2008, author = {Kroll-Ludwigs, Kathrin}, title = {Unification of Conflict of Laws in Europe.

This study investigated if previous findings on the beneficial effects of EMME would extend to online lecture videos and compared the effects of displaying the teacher's gaze cursor with displaying the more traditional mouse cursor as a tool to guide learners' attention. Novices (N = 124) studied a pre-recorded video lecture on how to model business processes in a 2 (mouse cursor absent/present) × 2 (gaze cursor absent/present) between-subjects design. Unexpectedly, we did not find significant effects of the presence of gaze or mouse cursors on mental effort and learning. However, participants who watched videos with the gaze cursor found it easier to follow the teacher. Overall, participants responded positively to the gaze cursor, especially when the mouse cursor was not displayed in the video.}, language = {en} } @article{HerzwurmKramsPietschetal.2012, author = {Herzwurm, Georg and Krams, Benedikt and Pietsch, Wolfram and Schockert, Sixten}, title = {Report from the 3rd international workshop on requirements prioritization for customer oriented software development (RePriCo'12)}, series = {ACM SIGSOFT Software Engineering Notes}, volume = {37}, journal = {ACM SIGSOFT Software Engineering Notes}, number = {4}, publisher = {Association for Computing Machinery}, address = {New York}, issn = {0163-5948}, doi = {10.1145/2237796.2237817}, pages = {32 -- 34}, year = {2012}, abstract = {Prioritization is an essential task within requirements engineering to cope with complexity and to establish focus properly.
