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{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.

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} } @inproceedings{StopforthFerreinSteinbauer2015, author = {Stopforth, Riaan and Ferrein, Alexander and Steinbauer, Gerald}, title = {Europe and South African collaboration on the Mechatronics and Robotics systems as part of the SA Robotics Center}, series = {ICRA 2015 Developing Countries Forum}, booktitle = {ICRA 2015 Developing Countries Forum}, pages = {3 S.}, year = {2015}, abstract = {Mechatronics consist of the integration of mechanical engineering, electronic integration and computer science/ engineering.

Collaboration between the European countries and South Africa is critical, as each country has different resources available, which the other countries might not have.

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} } @incollection{WolfFraentz2013, author = {Wolf, Martin and Fr{\"a}ntz, Birgit}, title = {Erfolgreiches IT-Marketing}, series = {Erfolgreiches IT-Marketing in Zeiten von Social Media, Cloud \& Co. - (CIO-Handbuch ; 2)}, booktitle = {Erfolgreiches IT-Marketing in Zeiten von Social Media, Cloud \& Co. - (CIO-Handbuch ; 2)}, edition = {1.
