One of the main challenges of this effort is to explain complex robotics contents in a way that pre-school children could follow the basic principles and ideas using examples from their world of experience. What sets apart our effort from other work is that part of the lecturing is actually done by a robot itself and that a quiz at the end of the lesson is done using robots as well. The humanoid robot Pepper from Softbank, which is a great platform for human-robot interaction experiments, was used to present a lecture on robotics by reading out the contents to the children making use of its speech synthesis capability. A quiz in a Runaround-game-show style after the lecture activated the children to recap the contents they acquired about how mobile robots work in principle. In this quiz, two LEGO Mindstorm EV3 robots were used to implement a strongly interactive scenario. Besides the thrill of being exposed to a mobile robot that would also react to the children, they were very excited and at the same time very concentrated. We got very positive feedback from the children as well as from their educators. To the best of our knowledge, this is one of only few attempts to use a robot like Pepper not as a tele-teaching tool, but as the teacher itself in order to engage pre-school children with complex robotics contents.}, language = {en} } @article{HeuermannSchiek1995, author = {Heuermann, Holger and Schiek, B.}, title = {Error corrected impedance measurements with a network analyzer}, series = {IEEE transactions on instrumentation and measurement : IM / Institute of Electrical and Electronics Engineers, Instrumentation and Measurement Group. 44 (1995), H. 2}, journal = {IEEE transactions on instrumentation and measurement : IM / Institute of Electrical and Electronics Engineers, Instrumentation and Measurement Group. 44 (1995), H. 2}, isbn = {0018-9456}, pages = {295 -- 299}, year = {1995}, language = {en} } @article{HeuermannSchiek1994, author = {Heuermann, Holger and Schiek, Burkhard}, title = {Error Corrected Impedance Measurements with a Network Analyzer}, pages = {125 -- 126}, year = {1994}, language = {en} } @article{BragardBragard2003, author = {Bragard, Michael and Bragard, G.}, title = {Erweiterungen f{\"u}r das CBL2-Messinterface von Texas-Instruments}, series = {Der mathematische und naturwissenschaftliche Unterricht : MNU ; Organ des Deutschen Vereins zur F{\"o}rderung des Mathematischen und Naturwissenschaftlichen Unterrichts e.V.}, volume = {56}, journal = {Der mathematische und naturwissenschaftliche Unterricht : MNU ; Organ des Deutschen Vereins zur F{\"o}rderung des Mathematischen und Naturwissenschaftlichen Unterrichts e.V.}, number = {2}, publisher = {Seeberger}, address = {Neuss}, issn = {0025-5866}, pages = {87 -- 88}, year = {2003}, abstract = {Das von Texas-Instruments (TI) vertriebene Interface CBL2 wird {\"u}ber einige TI-Grafik-Rechner (TI-92, TI-89 usw.) angesteuert.

A great deal of excellent research in the field exists, but practical applications at real disaster sites are scarce. Many projects concentrate on equipping robots with advanced capabilities, such as autonomous exploration or object manipulation. In spite of this, realistic application areas for such robots are limited to teleoperated reconnaissance or search. In this paper, we investigate how well state-of-the-art and off-the-shelf components and algorithms are suited for reconnaissance in current disaster-relief scenarios. The basic idea is to make use of some of the most common sensors and deploy some widely used algorithms in a disaster situation, and to evaluate how well the components work for these scenarios. We acquired the sensor data from two field experiments, one from a disaster-relief operation in a motorway tunnel, and one from a mapping experiment in a partly closed down motorway tunnel. Based on these data, which we make publicly available, we evaluate state-of-the-art and off-the-shelf mapping approaches. In our analysis, we integrate opinions and replies from first responders as well as from some algorithm developers on the usefulness of the data and the limitations of the deployed approaches, respectively. We discuss the lessons we learned during the two missions. These lessons are interesting for the community working in similar areas of urban search and rescue, particularly reconnaissance and search.}, language = {en} } @article{HeuermannErkens2005, author = {Heuermann, Holger and Erkens, H.}, title = {EVM- und BER-optimierter differentieller Einseitenbandmodulator / Erkens, H., Heuermann, H.}, series = {German Microwave Conference - GeMiC 2005 - : conference proceedings ; University of Ulm, April 5 - 7, 2005 [Elektronische Ressource] / ed.: Wolfgang Menzel.

Its heating system consists of different source and consumer circuits connected by a Zortstr{\"o}m reservoir. Our goal was to reduce the energy costs of the system as much as possible. Therefore, we analyzed its supply circuits. The first step towards optimization is a complete examination of the system: 1) Compilation of an object list for the system, 2) collection of the characteristic curves of the components, and 3) measurement of the load profiles of the heat and volume-flow demand. Instead of modifying the system manually and testing the solution by simulation, the second step was the creation of a global optimization program. The objective was to minimize the total energy costs for one year. We compare two different topologies and show opportunities for significant savings.}, language = {en} } @article{NoureddineBitzLaddetal.2015, author = {Noureddine, Yacine and Bitz, Andreas and Ladd, Mark E. and Th{\"u}rling, Markus and Ladd, Susanne C. and Schaefers, Gregor and Kraff, Oliver}, title = {Experience with magnetic resonance imaging of human subjects with passive implants and tattoos at 7 T: a retrospective study}, series = {Magnetic Resonance Materials in Physics, Biology and Medicine}, volume = {28}, journal = {Magnetic Resonance Materials in Physics, Biology and Medicine}, number = {6}, publisher = {Springer}, address = {Berlin}, issn = {1352-8661}, doi = {10.1007/s10334-015-0499-y}, pages = {577 -- 590}, year = {2015}, language = {en} } @article{AltherrEdererLorenzetal.2014, author = {Altherr, Lena and Ederer, Thorsten and Lorenz, Ulf and Pelz, Peter F. and P{\"o}ttgen, Philipp}, title = {Experimental validation of an enhanced system synthesis approach}, series = {Operations Research Proceedings 2014}, journal = {Operations Research Proceedings 2014}, editor = {L{\"u}bbecke, Marco and Koster, Arie and Letmathe, Peter and Madlener, Reihard and Peis, Britta and Walther, Grit}, publisher = {Springer}, address = {Basel}, isbn = {978-3-319-28695-2}, doi = {10.1007/978-3-319-28697-6_1}, pages = {6}, year = {2014}, abstract = {Planning the layout and operation of a technical system is a common task for an engineer. Typically, the workflow is divided into consecutive stages: First, the engineer designs the layout of the system, with the help of his experience or of heuristic methods. Secondly, he finds a control strategy which is often optimized by simulation. This usually results in a good operating of an unquestioned sys- tem topology. In contrast, we apply Operations Research (OR) methods to find a cost-optimal solution for both stages simultaneously via mixed integer program- ming (MILP). Technical Operations Research (TOR) allows one to find a provable global optimal solution within the model formulation. However, the modeling error due to the abstraction of physical reality remains unknown. We address this ubiq- uitous problem of OR methods by comparing our computational results with mea- surements in a test rig. For a practical test case we compute a topology and control strategy via MILP and verify that the objectives are met up to a deviation of 8.7\%.}, language = {en} } @article{SiepmannPfeifferTeichmann1988, author = {Siepmann, Thomas and Pfeiffer, J. and Teichmann, W.}, title = {Expertensystem zur spanenden Bearbeitung}, series = {Technische Mitteilungen Krupp (1988)}, journal = {Technische Mitteilungen Krupp (1988)}, address = {Essen}, year = {1988}, language = {de} } @article{Siepmann1991, author = {Siepmann, Thomas}, title = {Expertensysteme in der rechnerintegrierten Produktion}, series = {Einf{\"u}hrung in die CIM-Praxis : rechnerintegrierte Produktion / hrsg. von Gerhard Neipp ...}, journal = {Einf{\"u}hrung in die CIM-Praxis : rechnerintegrierte Produktion / hrsg. von Gerhard Neipp ...}, publisher = {VDI-Verl.}, address = {D{\"u}sseldorf}, isbn = {3-18-401098-8}, pages = {187 -- 198}, year = {1991}, language = {de} } @article{Siepmann1999, author = {Siepmann, Thomas}, title = {Exploitation Plan of the TELEflow Project}, address = {Brussels}, year = {1999}, language = {en} } @article{ReinhardtBitzElOuardietal.2007, author = {Reinhardt, T. and Bitz, Andreas and El Ouardi, A. and Streckert, J. and Sommer, A. and Lerchl, A. and Hansen, V.}, title = {Exposure set-ups for in vivo experiments using radial waveguides}, series = {Radiation Protection Dosimetry}, volume = {124}, journal = {Radiation Protection Dosimetry}, number = {1}, issn = {1742-3406}, doi = {10.1093/rpd/ncm370}, pages = {21 -- 26}, year = {2007}, language = {en} } @article{SchlamannVoigtMaderwaldetal.2010, author = {Schlamann, Marc and Voigt, Melanie A. and Maderwald, Stefan and Bitz, Andreas and Kraff, Oliver and Ladd, Susanne C. and Ladd, Mark E. and Forsting, Michael and Wilhelm, Hans}, title = {Exposure to high-field MRI does not affect cognitive function}, series = {Journal of Magnetic Resonance Imaging}, volume = {31}, journal = {Journal of Magnetic Resonance Imaging}, number = {5}, publisher = {Wiley-Liss}, address = {New York}, issn = {1522-2586}, doi = {10.1002/jmri.22065}, pages = {1061 -- 1066}, year = {2010}, abstract = {Purpose To assess potential cognitive deficits under the influence of static magnetic fields at various field strengths some studies already exist. These studies were not focused on attention as the most vulnerable cognitive function. Additionally, mostly no magnetic resonance imaging (MRI) sequences were performed. Materials and Methods In all, 25 right-handed men were enrolled in this study. All subjects underwent one MRI examination of 63 minutes at 1.5 T and one at 7 T within an interval of 10 to 30 days. The order of the examinations was randomized. Subjects were referred to six standardized neuropsychological tests strictly focused on attention immediately before and after each MRI examination. Differences in neuropsychological variables between the timepoints before and after each MRI examination were assessed and P-values were calculated Results Only six subtests revealed significant differences between pre- and post-MRI. In these tests the subjects achieved better results in post-MRI testing than in pre-MRI testing (P = 0.013-0.032). The other tests revealed no significant results. Conclusion The improvement in post-MRI testing is only explicable as a result of learning effects. MRI examinations, even in ultrahigh-field scanners, do not seem to have any persisting influence on the attention networks of human cognition immediately after exposure.}, language = {en} } @article{FerreinFritzLakemeyer2003, author = {Ferrein, Alexander and Fritz, Christian and Lakemeyer, Gerhard}, title = {Extending DTGOLOG with Options / Ferrein, Alexander ; Fritz, Christian ; Lakemeyer, Gerhard}, series = {IJCAI-03, Proceedings of the Eighteenth International Joint Conference on Artificial Intelligence, Acapulco, Mexico, August 9-15, 2003}, journal = {IJCAI-03, Proceedings of the Eighteenth International Joint Conference on Artificial Intelligence, Acapulco, Mexico, August 9-15, 2003}, pages = {1391 -- 1393}, year = {2003}, language = {en} } @article{PrumeMuraltCalameetal.2007, author = {Prume, Klaus and Muralt, Paul and Calame, Florian and Schmitz-Kempen, Thorsten}, title = {Extensive electromechanical characterization of PZT thin films for MEMS applications by electrical and mechanical excitation signals / Prume, Klaus ; Muralt, Paul ; Calame, Florian ; Schmitz-Kempen, Thorsten ; Tiedke, Stephan}, series = {Journal of Electroceramics. 19 (2007), H. 4}, journal = {Journal of Electroceramics. 19 (2007), H. 4}, isbn = {1385-3449}, pages = {407 -- 411}, year = {2007}, language = {en} }
