In previous experiments, the collective behavior of 15 autonomous swarm robots, driven by a simple bio-inspired control algorithm, was investigated: in two different environmental conditions, the ability of the robots to aggregate below a light source was tested. Distinct approaches to predict the dynamics of the spatial distribution were made by two different modeling approaches: one model was constructed in a compartmental manner (ODEs). In parallel, a space-continuous model (PDEs) was constructed. Both models show a high degree of similarity concerning the modeling of concrete environmental factors (light), but due to their different basic approaches, show also significant differences in their implementation. However, the predictions of both models compare well to the observed behavior of the robotic swarm, thus both models can be used to develop further extensions of the algorithm as well as different experimental setups without the need to run extensive real robotic preliminary experiments.}}, author = {{Hamann, Heiko and Schmickl, Thomas and Wörn, Heinz and Crailsheim, Karl}}, booktitle = {{IEEE/RSJ 2008 International Conference on Intelligent Robots and Systems (IROS'08)}}, pages = {{1415----1420}}, publisher = {{IEEE Press}}, title = {{{Spatial Macroscopic Models of a Bio-Inspired Robotic Swarm Algorithm}}}, doi = {{10.1109/IROS.2008.4651038}}, year = {{2008}}, } @article{20369, abstract = {{Designing and analyzing self-organizing systems such as robotic swarms is a challenging task even though we have complete knowledge about the robot’s interior. It is difficult to determine the individual robot’s behavior based on the swarm behavior and vice versa due to the high number of agent–agent interactions. A step towards a solution of this problem is the development of appropriate models which accurately predict the swarm behavior based on a specified control algorithm. Such models would reduce the necessary number of time-consuming simulations and experiments during the design process of an algorithm. In this paper we propose a model with focus on an explicit representation of space because the effectiveness of many swarm robotic scenarios depends on spatial inhomogeneity. We use methods of statistical physics to address spatiality. Starting from a description of a single robot we derive an abstract model of swarm motion. The model is then extended to a generic model framework of communicating robots. In two examples we validate models against simulation results. Our experience shows that qualitative correctness is easily achieved, while quantitative correctness is disproportionately more difficult but still possible.}}, author = {{Hamann, Heiko and Wörn, Heinz}}, issn = {{1935-3812}}, journal = {{Swarm Intelligence}}, number = {{2-4}}, pages = {{209--239}}, title = {{{A framework of space–time continuous models for algorithm design in swarm robotics}}}, doi = {{10.1007/s11721-008-0015-3}}, volume = {{2}}, year = {{2008}}, } @article{20478, author = {{Baumeister, Jochen}}, journal = {{Sportverl Sportschad}}, number = {{3}}, pages = {{135--138}}, title = {{{Sensomotorik: Kreuzbandverletzung hinterläßt Spuren im Gehirn}}}, volume = {{22}}, year = {{2008}}, } @article{20479, author = {{Baumeister, Jochen and Barthel, T and Geiss, K.R. and Weiss, M}}, journal = {{Nutr Neurosci}}, number = {{3}}, pages = {{103--110}}, title = {{{Influence of phasphatidylserine on cognitive performance and cortical activity after induced stress}}}, volume = {{11}}, year = {{2008}}, } @article{20480, author = {{Baumeister, Jochen and Reinecke, K and Liesen, H and Weiss, M}}, journal = {{Eur J Appl Physiol}}, number = {{625}}, pages = {{625--631}}, title = {{{Cortical activity of skilled performance in a complex sports related motor task}}}, volume = {{104}}, year = {{2008}}, } @article{20481, author = {{Baumeister, Jochen and Reinecke, K and Weiss, M}}, journal = {{Scand J Med Sci Sports}}, number = {{4}}, pages = {{473--484}}, title = {{{Changed cortical activity after anterior cruciate ligament reconstruction in a joint position paradigm: an EEG study}}}, volume = {{18}}, year = {{2008}}, } @inbook{20711, author = {{Monien, Burkhard and Lorenz, Ulf and Warner, Daniel}}, booktitle = {{Taschenbuch der Algorithmen}}, isbn = {{9783540763932}}, title = {{{Der Alphabeta-Algorithmus für Spielbäume: Wie bringe ich meinen Computer zum Schachspielen?}}}, doi = {{10.1007/978-3-540-76394-9_28}}, year = {{2008}}, } @misc{2076, author = {{Krimphove, Dieter}}, booktitle = {{Das neue Lexikon der Betriebswirtschaftslehre}}, publisher = {{Oldenbourg Verlag}}, title = {{{Bürgschaft}}}, year = {{2008}}, } @misc{2077, author = {{Krimphove, Dieter}}, booktitle = {{Das neue Lexikon der Betriebswirtschaftslehre}}, publisher = {{Oldenbourg Verlag}}, title = {{{Eigentumsvorbehalt}}}, year = {{2008}}, } @misc{2078, author = {{Krimphove, Dieter}}, booktitle = {{Das neue Lexikon der Betriebswirtschaftslehre}}, publisher = {{Oldenbourg Verlag}}, title = {{{Garantievertrag}}}, year = {{2008}}, } @misc{2079, author = {{Krimphove, Dieter}}, booktitle = {{Das neue Lexikon der Betriebswirtschaftslehre}}, publisher = {{Oldenbourg Verlag}}, title = {{{Grundschuld}}}, year = {{2008}}, } @misc{2080, author = {{Krimphove, Dieter}}, booktitle = {{Das neue Lexikon der Betriebswirtschaftslehre}}, publisher = {{Oldenbourg Verlag}}, title = {{{Hypothek}}}, year = {{2008}}, } @misc{2081, author = {{Krimphove, Dieter}}, booktitle = {{Das neue Lexikon der Betriebswirtschaftslehre}}, publisher = {{Oldenbourg Verlag}}, title = {{{Kreditsicherheiten}}}, year = {{2008}}, } @misc{2082, author = {{Krimphove, Dieter}}, booktitle = {{Das neue Lexikon der Betriebswirtschaftslehre}}, publisher = {{Oldenbourg Verlag}}, title = {{{Nutzungspfand}}}, year = {{2008}}, }
