Based on this, we introduce a model-based bootstrap (MBB) for higher-dimensional input variables. This test can be used to check whether a sequence of independent and identically distributed observations belongs to such a parametric family. The approach is based on the empirical residual process introduced by Stute (Ann Statist 25:613-641, 1997). In contrast to Stute and Zhu's approach (2002) Stute \& Zhu (Scandinavian J Statist 29:535-545, 2002), a transformation is not required. Thus, any problems associated with non-parametric regression estimation are avoided. As a result, the MBB method is much easier for users to implement. To illustrate the power of the MBB based tests, a small simulation study is performed. Compared to the approach of Stute \& Zhu (Scandinavian J Statist 29:535-545, 2002), the simulations indicate a slightly improved power of the MBB based method. Finally, both methods are applied to a real data set.}, language = {en} } @article{HavermannSeiler2006, author = {Havermann, Marc and Seiler, F.}, title = {Boundary Layer Influence on Supersonic Jet/Cross-Flow Interaction in Hypersonic Flow / Havermann, M. ; Seiler, F.}, series = {Notes on Numerical Fluid Mechanics and Multidisciplinary Design. 92 (2006)}, journal = {Notes on Numerical Fluid Mechanics and Multidisciplinary Design. 92 (2006)}, publisher = {-}, isbn = {1612-2909}, pages = {281 -- 288}, year = {2006}, language = {en} } @article{ZastrowRieder1980, author = {Zastrow, Udo and Rieder, G.}, title = {Bracketing eigenvalues of an oscillating elastic body by integral equations}, series = {Bracketing of eigenfrequencies of continous structures : Euromech Colloquium, no. 112, M{\´a}traf{\"u}red (Hungary), 21 - 23 February, 1979 / ed. by {\`A}.

These parts are typically managed on-sight, i.e. with no signalling and train protection systems ensuring the freedom of movement. This is possible due to the rather short braking distances of individual vehicles and shunting consists. The present article analyses the braking behaviour of such shunting units. For this purpose, a dedicated model is developed. It is calibrated on published results of brake tests and validated against a high-definition model for low-speed applications. Based on this model, multiple simulations are executed to obtain a Monte Carlo simulation of the resulting braking distances. Based on the distribution properties and established safety levels, the risk of exceeding certain braking distances is evaluated and maximum braking distances are derived. Together with certain parameters of the system, these can serve in the design and safety assessment of driver assistance systems and automation of these processes.}, language = {en} } @article{AckermannJaegerOsterfeldetal.1993, author = {Ackermann, Hans-Josef and J{\"a}ger, Michael and Osterfeld, Utz and Hornung, Christoph}, title = {Building a Multimedia ISDN PC / J{\"a}ger, Michael ; Osterfeld, Utz ; Ackermann, Hans-Josef ; Hornung, Christoph}, series = {Institute of Electrical and Electronics Engineers: IEEE computer graphics and applications. 13 (1993), H. 5}, journal = {Institute of Electrical and Electronics Engineers: IEEE computer graphics and applications. 13 (1993), H. 5}, isbn = {0272-1716}, pages = {24 -- 33}, year = {1993}, language = {en} } @article{GerhardtKrueger1997, author = {Gerhardt, Hans Joachim and Kr{\"u}ger, O.}, title = {Building shape influence on local wind loads}, series = {Proceedings of the 2nd European \& African Conference on Wind Engineering : 2 EACWE, Palazzo Ducale, Genova, Italy, June 22-26, 1997 / ed. by Giovanni Solari. - Vol. 2}, journal = {Proceedings of the 2nd European \& African Conference on Wind Engineering : 2 EACWE, Palazzo Ducale, Genova, Italy, June 22-26, 1997 / ed. by Giovanni Solari. - Vol. 2}, publisher = {Servizi Grafici Editoriali}, address = {Padova}, isbn = {88-86281-19-6}, pages = {XIX, S. 1017 - 1998 : Ill., graph.

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} } @article{PietschSteinbauer1994, author = {Pietsch, Wolfram and Steinbauer, Dieter}, title = {Business Process Reengineering}, series = {Wirtschaftsinformatik. 36 (1994), H. 5}, journal = {Wirtschaftsinformatik. 36 (1994), H. 5}, isbn = {0937-6429}, pages = {502 -- 505}, year = {1994}, language = {en} } @article{SchmitzWeber2012, author = {Schmitz, Philipp and Weber, Martin}, title = {Buying and selling behavior of individual investors in option-like securities}, series = {Die Betriebswirtschaft : DBW}, volume = {72}, journal = {Die Betriebswirtschaft : DBW}, number = {5}, publisher = {Sch{\"a}ffer-Poeschel}, address = {Stuttgart}, issn = {0342-7064}, doi = {10.2139/ssrn.2055088}, pages = {409 -- 426}, year = {2012}, abstract = {We analyze the trading behavior of individual investors in option-like securities, namely bankissued warrants, and thus expand the growing literature of investors behavior to a new kind of securities. A unique data set from a large German discount broker gives us the opportunity to analyze the trading behavior of 1,454 investors, making 89,958 transactions in 6,724 warrants on 397 underlyings. In different logit regression, we make use of the facts that investors can speculate on rising and falling prices of the underlying with call and put warrants and that we also have information about the stock portfolios of the investors. We report several facts about the trading behavior of individual investors in warrants that are consistent with the literature on the behavior of individual investors in the stock market. The warrant investors buy calls and sell puts if the price of the underlying has decreased over the past trading days and they sell calls and buy puts if the price of the underlying has increased. That means, the investors follow negative feedback trading strategies in all four trading categories observed. In addition, we find strong evidence for the disposition effect for call as well as put warrants, which is reversed in December. The trading behavior is also influenced if the underlying reaches some exceptionally prices, e.g. highs, lows or the strike price. We show that hedging, as one natural candidate to buy puts, does not play an important role in the market for bank-issued warrants.}, language = {en} }
