Methods: Therefore, a simplified 3D model is derived and the mathematical coherences are described. Different mathematical solutions are presented for special boundary conditions and a method called "vibration mode coupling by asymmetry" is derived. Results: It could be shown that a symmetrical system with a machine design, where the center of gravity lies symmetrically between the machine feet with a vertical distance, and where all actuators are identical, represents a system, where all vibration shapes but one can be influenced by the controllers, when the gyroscopic effect can be neglected. In this case, a special vibration shape occurs—where the machine is only rotating at its vertical axis—which cannot be influenced by the controllers. When the stiffness and/or damping in axial and/or horizontal direction of only one actuator will be changed—which will lead to an asymmetrical system—the vibration shape with pure rotation at the vertical axis will not exist anymore. Now, the vibration shapes will become more coupled and they all can be influenced by the controllers, which is here called "vibration mode coupling by asymmetry". Conclusions: With the here presented method of "vibration mode coupling by asymmetry", all vibrations mode shapes can now be active controlled.}, language = {en} } @inproceedings{WachterWernerHerzogetal.2020, author = {Wachter, Raimund and Werner, Ulrich and Herzog, Hans-Georg and Bauer, Christian}, title = {Vibration behaviour of a 11 kW two pole induction motor mounted on elastic steel frame foundation with actuator system}, series = {12th International Conference on Vibrations in Rotating Machinery}, booktitle = {12th International Conference on Vibrations in Rotating Machinery}, editor = {Wachter, Raimund and Werner, Ulrich and Herzog, Hans-Georg and Bauer, Christian}, publisher = {CRC Press}, isbn = {9781003132639}, pages = {12}, year = {2020}, abstract = {This paper describes the vibration behaviour of a small (11 kW) two pole induction motor, which is mounted on an elastic steel frame foundation with a special actuator system.

For single aerofoils, the resulting broadband noise reduction is known to follow spectral scaling laws. However, transferring serrated leading edges to rotating machinery, results in noise radiation patterns of significantly increased complexity, impeding to allocate the observed noise reduction to the underlying physical mechanisms. The current study aims at concatenating the scaling laws for stationary aerofoil and rotating-blade application and thus at providing valuable information on the aeroacoustic transferability of leading edge serrations. For the pursued approach, low-pressure axial fans are designed, obtaining identical serrated fan blade geometries than previously analyzed single aerofoils, hence allowing for direct comparison. Highly similar spectral noise reduction patterns are obtained for the broadband noise reduction of the serrated rotors, generally confirming the transferability and showing a scaling with the geometrical parameters of the serrations as well as the inflow conditions. Continuative analysis of the total noise reduction, however, constrains the applicability of the scaling laws to a specific operating range of the rotors and motivates for a devaluation of the scaling coefficients regarding additional rotor-specific effects.}, language = {en} } @incollection{Kaiser2017, author = {Kaiser, Markus}, title = {Design thinking}, series = {Transforming Media: neue Gesch{\"a}ftsmodelle in der digitalen Welt}, volume = {2017}, booktitle = {Transforming Media: neue Gesch{\"a}ftsmodelle in der digitalen Welt}, publisher = {Verlag Dr. Gabriele Hooffacker}, address = {M{\"u}nchen}, isbn = {978-3-9815512-3-5}, pages = {56 - 61}, year = {2017}, abstract = {Egal ob Print, Fernsehen oder Radio: Der klassische Journalismus sucht im Medienwandel nach Wegen, sich weiterhin tragen zu k{\"o}nnen.

Arising from this discussion, several elements of a new definition of social resilience are presented. Social resilience, especially within the context of poverty, is based on different sources, such as available common goods, reliable networks or civil society organisations.

The challenge is not to find adversarial examples, but rather to find them efficiently, ideally in real time. We show two novel methods that increase the efficiency of black-box search algorithms for adversarial examples: The first uses a relevance mask, i.e., a bitmask on the original image that restricts the search to those pixels that appear to be more relevant to the attacked classifier than others. The second exploits the discovery of merge drift, a phenomenon that negatively affects search algorithms that are based on the merging of image candidates.

The effects of four influencing parameters (IP) are tested, characterizing the inflow conditions as well as the serration geometry. A total of 65 target values in the time and frequency domains are defined and can be approximated with high accuracy by individual artificial neural networks. Furthermore, the validation of the model against fully independent test points within the experimental space yields a remarkable fit, even for the spectral distribution in 1/3-octave bands, proving the ability of the model to generalize. A metaheuristic multi-objective optimization approach provides two-dimensional Pareto optimal solutions for selected pairs of target values. This is particularly important for reconciling opposing trends, such as the noise reduction capability and aerodynamic performance.

Such catalyst systems have yet to be practically utilized. Here, we demonstrate a compact electrically heated photo- and thermal annular reactor module to reduce CO2 to CO, via the reverse water gas shift reaction. A first-principles-based design approach was taken in developing a SiO2 on an Al photo- and thermal catalyst system for the model photo- and thermal indium oxide hydroxide (In2O3-x(OH)y) catalysts. A 5-fold light enhancement in the CO production rate and over 70 h of stable CO production were achieved. This represents the highest light enhancement effect reported for this model photocatalyst to date.

Furthermore, studies conducted while the first author of this study was working for an NGO, report significantly higher emissions. Based on an adaptation of a meta-regression analysis to the field of environmental performance measurement, we are able to provide new insights about the influence of the change of individual drivers on the emission level. Examples of these insights include a one-third increase in cattle stock is associated with an increase in emissions of 29.45 t/km2. We also find that publications where the first author works for an NGO reported an emission level 87.04 t/km2 higher than other publications. These findings enable the identification of the main drivers of emissions, while helping to explain the heterogeneity of existing studies. Based on the findings of this study, companies can take reliable measures to reduce the external climate effects of their products.}, language = {en} } @incollection{AslansefatSorokosWhitingetal.2020, author = {Aslansefat, Koorosh and Sorokos, Ioannis and Whiting, Declan and Tavakoli Kolagari, Ramin and Papadopoulos, Yiannis}, title = {SafeML: Safety Monitoring of Machine Learning Classifiers Through Statistical Difference Measures}, series = {Model-Based Safety and Assessment}, booktitle = {Model-Based Safety and Assessment}, publisher = {Springer International Publishing}, address = {Cham}, isbn = {9783030589196}, issn = {0302-9743}, doi = {10.1007/978-3-030-58920-2_13}, pages = {197 -- 211}, year = {2020}, language = {en} } @article{SpiegelhalderAckerBaumeisteretal.2020, author = {Spiegelhalder, Kai and Acker, Jens and Baumeister, Harald and B{\"u}ttner-Teleaga, Antje and Danker-Hopfe, Heidi and Ebert, David D. and Fietze, Ingo and Frase, Lukas and Klein, Sarah and Lehr, Dirk and Maun, Andy and Mertel, Isabella and Richter, Kneginja and Riemann, Dieter and Sauter, Cornelia and Schilling, Claudia and Schlarb, Angelika A. and Specht, Markus and Steinmetz, Lisa and Weeß, Hans G. and Cr{\"o}nlein, Tatjana}, title = {Digitale Behandlungsangebote f{\"u}r Insomnie - eine {\"U}bersichtsarbeit}, series = {Somnologie}, volume = {24}, journal = {Somnologie}, number = {2}, publisher = {Springer Science and Business Media LLC}, issn = {1432-9123}, doi = {10.1007/s11818-020-00238-9}, pages = {106 -- 114}, year = {2020}, abstract = {ZusammenfassungDigital angebotene psychologische Interventionen gegen Schlafst{\"o}rungen sind aktuell ein sehr intensiv bearbeitetes Forschungsthema.

Studies in strategic management and finance research have analyzed value creation through product and geographic diversification from a shareholder's perspective. This study completes this picture by analyzing the bondholders' perspective. It is suggested that product diversification creates value for bondholders, while geographic diversification destroys bondholder value. The hypotheses are tested on a sample of S\&P 1,200 firms in 2001-2011 using a fixed-effects panel model. Drawing on prior research, bondholder value creation is measured using the Merton model. The empirical results support the hypothesis that bondholders gain value through product diversification but lose value through geographic diversification. Considering prior research results, these results show that product diversification is preferable for bondholders, while geographic diversification is preferable from a shareholder's perspective. The opposite effects of both diversification strategies on shareholders, respectively, bondholders offer an important new perspective on corporate diversification. The results show that firms with a high level of corporate debt should struggle to justify a strategy involving geographic dispersion of activities and support a more diversified product portfolio strategy. This study also offers several avenues for investigating the bondholder's perspective on corporate diversification in more detail.}, language = {en} } @inproceedings{SteinbrinkKochMayetal.2020, author = {Steinbrink, Marco and Koch, Philipp and May, Stefan and Jung, Bernhard and Schmidpeter, Michael}, title = {State Machine for Arbitrary Robots for Exploration and Inspection Tasks}, series = {Proceedings of the 2020 4th International Conference on Vision, Image and Signal Processing}, booktitle = {Proceedings of the 2020 4th International Conference on Vision, Image and Signal Processing}, publisher = {ACM}, address = {New York, NY, USA}, doi = {10.1145/3448823.3448857}, pages = {6}, year = {2020}, abstract = {In this paper, a novel state machine for mobile robots is described that enables a direct use for exploration and inspection tasks.
