Industry, and in particular engineers who shape industrial developments, have a special role to play as they are confronted with the responsibility to holistically reflect sustainability in industrial processes. This means that, in addition to the technical specifications, engineers must also question the effects of their own actions on an ecological, economic and social level in order to ensure sustainable action and contribute to the achievement of the SDGs. However, this requires competencies that enable engineers to apply all three pillars of sustainability to their own field of activity and to understand the global impact of industrial processes. In this context, it is relevant to understand how industry already reflects sustainability and to identify competences needed for sustainable development.}, language = {en} } @inproceedings{StepkesZimmermannMuelleretal.2007, author = {Stepkes, Hermann and Zimmermann, J. and M{\"u}ller, Karsten and Siekmann, Marko and Pinnekamp, Josef}, title = {Economical rehabilitation of sewer systems by ground penetration radar investigations}, series = {Strategic asset management of water supply and wastewater infrastructures : invited papers from the 2nd IWA Leading Edge Conference on Strategic Asset Management (LESAM), Lisbon, October [17 - 19] 2007 / ed. by Helene Alegre and Maria do C{\´e}u Almeida}, booktitle = {Strategic asset management of water supply and wastewater infrastructures : invited papers from the 2nd IWA Leading Edge Conference on Strategic Asset Management (LESAM), Lisbon, October [17 - 19] 2007 / ed. by Helene Alegre and Maria do C{\´e}u Almeida}, publisher = {IWA Publ.}, address = {London}, isbn = {9781843391869}, pages = {501 -- 520}, year = {2007}, language = {en} } @inproceedings{StephanHeuermannPrantner2016, author = {Stephan, Achim and Heuermann, Holger and Prantner, Michael}, title = {Cutting human tissue with novel atmospheric-pressure microwave plasma jet}, series = {46th European Microwave Conference (EuMC)}, booktitle = {46th European Microwave Conference (EuMC)}, publisher = {IEEE}, isbn = {978-2-87487-043-9}, doi = {10.1109/EuMC.2016.7824490}, pages = {902 -- 905}, year = {2016}, language = {en} } @inproceedings{StenderRitz2003, author = {Stender, Michael and Ritz, Thomas}, title = {Modeling of business-to-business mobile commerce processes}, series = {Electronic proceedings / ICPR 17, 17th International Conference on Production Research [Blacksburg, Virginia, USA, August 3 - 7, 2003]}, booktitle = {Electronic proceedings / ICPR 17, 17th International Conference on Production Research [Blacksburg, Virginia, USA, August 3 - 7, 2003]}, edition = {CD-ROM-Ausg.}, address = {Blacksburg, Va.}, isbn = {0-9721257-3-6}, year = {2003}, language = {en} } @inproceedings{SteinbauerFerrein2019, author = {Steinbauer, Gerald and Ferrein, Alexander}, title = {CogRob 2018 : Cognitive Robotics Workshop.

These "paradox" fractures can be explained by a phenomenological extension strain failure criterion. In the past, a simple empirical criterion for fracture initiation in brittle rock has been developed. But this criterion makes unrealistic strength predictions in biaxial compression and tension. A new extension strain criterion overcomes this limitation by adding a weighted principal shear component. The weight is chosen, such that the enriched extension strain criterion represents the same failure surface as the Mohr-Coulomb (MC) criterion. Thus, the MC criterion has been derived as an extension strain criterion predicting failure modes, which are unexpected in the understanding of the failure of cohesive-frictional materials. In progressive damage of rock, the most likely fracture direction is orthogonal to the maximum extension strain. The enriched extension strain criterion is proposed as a threshold surface for crack initiation CI and crack damage CD and as a failure surface at peak P. Examples show that the enriched extension strain criterion predicts much lower volumes of damaged rock mass compared to the simple extension strain criterion.}, language = {en} } @inproceedings{SpaeteHafnerSchwarzer2000, author = {Sp{\"a}te, Frank and Hafner, B. and Schwarzer, Klemens}, title = {A system for solar process heat for decentralized applications in developing countries}, series = {ISES 1999 Solar World Congress, Jerusalem, Israel, July 4-9, 1999 : conference proceedings / ed.

Thus our developed mission scenario based on the joint NASA/ESA Titan Saturn System Mission baselines solar electric propulsion to improve mission flexibility and transfer time. For the calculation of near-globally optimal low-thrust trajectories, we have used a method called Evolutionary Neurocontrol, which is implemented in the low-thrust trajectory optimization software InTrance. The studied solar electric propulsion scenario covers trajectory optimization of the interplanetary transfer including variations of the spacecraft's thrust level, the thrust unit's specific impulse and the solar power generator power level. Additionally developed software extensions enabled trajectory optimization with launcher-provided hyperbolic excess energy, a complex solar power generator model and a variable specific impulse ion engine model. For the investigated mission scenario, Evolutionary Neurocontrol yields good optimization results, which also hold valid for the more elaborate spacecraft models. Compared to Cassini/Huygens, the best found solutions have faster transfer times and a higher mission flexibility in general.}, language = {en} } @inproceedings{SpohrSchirraHoeflingetal.2013, author = {Spohr, A. and Schirra, Julian and Hoefling, J. and Schedl, A.}, title = {Wing weight estimation methodology for highly non-planar lifting systems during conceptual design}, series = {Deutscher Luft- und Raumfahrtkongress 2013 : 10.9. - 12.9.2013, Stuttgart}, booktitle = {Deutscher Luft- und Raumfahrtkongress 2013 : 10.9. - 12.9.2013, Stuttgart}, organization = {Deutscher Luft- und Raumfahrtkongress <62, 2013, Stuttgart>}, pages = {Publ. online}, year = {2013}, language = {en} }
