It uses key-frame based animation. The number of animated objects may grow constantly in complex simulation models, which might lead to an amount of animations that is too big to be computed in real-time. By the use of a dynamic adjustment, the presented algorithm prefers important animations. Less relevant animations are updated rarely, whereby the selection itself is taken by multiple indicators, e.g. the visible size of the animated object on the screen, in order to keep a good optical impression. Dependent on the computing power of the computer, the algorithm controls the animations in such a way, that the fluid visualization of a large number of objects is still possible. Though the algorithm is to be used within a material flow simulator, it is moreover implemented in a specific animation editor, which allows the design and control of animation schemes. It supports the use of grouping to allow the creation of hierarchical structures for complex animations in a fast and easy manner. The evaluation of the algorithm is proven by a test scene, consisting of tens of thousands animated objects. }}, author = {{Laroque, Christoph and Fischer, Matthias and Dangelmaier, Wilhelm and Eikel, Benjamin}}, booktitle = {{Industrial Simulation Conference (ISC 2008)}}, pages = {{306--310}}, publisher = {{EUROSIS-ETI}}, title = {{{Dynamic Control of Animation Schemes for the Efficient 3D-Visualization of Material Flow Simulations}}}, year = {{2008}}, } @inproceedings{18141, abstract = {{Dieser Artikel beschreibt eine Methode zur Animation einer großen Anzahl von Objekten zur dynamischen 3D-Visualisierung eines Simulationsmodells mittels der Materialflusssimulation auf Basis von Schlüsselbildern.

The maximal number of allowed hops might be bounded with the motivation to guarantee small latency. We introduce hybrid connectivity games to study the impact of selfishness on this kind of infrastructure. Mobile devices are represented by selfish players, each of which aims at establishing an uplink path to the base station minimizing its individual cost. Our model assumes that intermediate nodes on an uplink path are reimbursed for transmitting the packets of other devices. The reimbursements can be paid either by a benevolent network operator or by the senders of the packets using micropayments via a clearing agency that possibly collects a small percentage as commission. These different ways to implement the payments lead to different variants of the hybrid connectivity game. Our main findings are: (1) If there is no constraint on the number of allowed hops on the path to the base station, then the existence of equilibria is guaranteed regardless of whether the network operator or the senders pay for forwarding packets. (2) If the network operator pays, then the existence of equilibria is guaranteed only if at most one intermediate node is allowed, i.e., for at most two hops on the uplink path of a device, but not if the maximal number of allowed hops is three or larger. (3) In contrast, if the senders pay for forwarding their packets, then equilibria are guaranteed to exist given any bound on the number of allowed hops. The equilibrium analysis presented in this paper gives a first game theoretical motivation for the implementation of micropayment schemes in which senders pay for forwarding their packets. We further support this evidence by giving an upper bound on the Price of Anarchy for this kind of hybrid connectivity games that is independent of the number of nodes, but only depends on the number of hops and the power gradient.}}, author = {{Ackermann, Heiner and Briest, Patrick and Fanghänel, Alexander and Vöcking, Berthold}}, isbn = {{9783540771043}}, journal = {{Internet Mathematics}}, number = {{4}}, pages = {{459--475}}, publisher = {{Springer}}, title = {{{Who Should Pay for Forwarding Packets?}}}, doi = {{10.1007/978-3-540-77105-0_21}}, volume = {{5}}, year = {{2008}}, } @inproceedings{22338, author = {{Kriegel, Nils-Peter}}, booktitle = {{International Rubber Mixing Symposium}}, title = {{{Systematic analysis of the synchronization of twin screw extruders}}}, volume = {{1}}, year = {{2008}}, } @inproceedings{22339, author = {{Adelt, Philipp and Schmidt, Alexander and Esau, Natascha and Kleinjohann, Lisa and Kleinjohann, Bernd and Rose, Mirko}}, booktitle = {{MSC2008}}, isbn = {{978-1-4244-2224-1}}, pages = {{619--624}}, title = {{{Approximation of Environment Models for an Air Gap Adjustment System in a Hybrid Planning Context}}}, doi = {{10.1109/ISIC.2008.4635937}}, year = {{2008}}, } @inproceedings{22340, author = {{Esau, Natascha and Adelt, Philipp and Schmidt, Alexander and Rose, Mirko}}, booktitle = {{AISM 2008. 3rd Asia International Symposium on Mechatronics}}, pages = {{39--44}}, title = {{{Interval Optimization in a Hybrid Planner Context for an Air Gap Adaptation System}}}, volume = {{3}}, year = {{2008}}, } @inproceedings{22341, author = {{Gausemeier, Jürgen and Kahl, Sascha and Zimmer, Detmar and Schmidt, Alexander}}, booktitle = {{AISM 2008. 3rd Asia International Symposium on Mechatronics}}, pages = {{544--549}}, title = {{{Holistic Conceptual Design of Self-Optimizing Systems}}}, volume = {{3}}, year = {{2008}}, } @inproceedings{22342, author = {{Schmidt, Alexander and Adelt, Philipp and Esau, Natascha}}, booktitle = {{International Conference on Instrumentation, Control and Information Technology}}, isbn = {{978-4-907764-30-2}}, pages = {{653--658}}, publisher = {{Society of Instrument and Control Engineers (SICE)}}, title = {{{Integrating dynamic track sectioning into a hybrid planning infrastructure}}}, doi = {{10.1109/SICE.2008.4654737}}, volume = {{47}}, year = {{2008}}, } @inproceedings{22343, author = {{Gausemeier, Jürgen and Podlogar, Herbert and Donoth, Jörg and Zimmer, Detmar and Schmidt, Alexander}}, booktitle = {{International Conference on Systems Engineering}}, isbn = {{978-0-7695-3331-5}}, pages = {{474--479}}, publisher = {{University of Nevada}}, title = {{{Determination of Active Pattern during the Conceptual Design of Self-Optimizing Systems Demonstrated by an Air Gap Adjustment System}}}, doi = {{10.1109/ICSEng.2008.60}}, volume = {{19}}, year = {{2008}}, } @inproceedings{22344, author = {{Schmidt, Alexander and Esau, Natascha and Adelt, Philipp and Stern, Claudius}}, booktitle = {{IEEE International Conference on Mechatronics and Automation}}, isbn = {{978-1-4244-2632-4}}, pages = {{797--802}}, title = {{{Dynamic optimization of track sectioning in mechatronic systems for a hybrid planner}}}, doi = {{10.1109/ICMA.2008.4798859}}, volume = {{5}}, year = {{2008}}, } @inproceedings{22345, author = {{Henkler, Stefan and Hirsch, Martin and Kahl, Sascha and Schmidt, Alexander}}, booktitle = {{Computers and Information in Engineering Conference, Parts A and B}}, isbn = {{0-7918-3831-5}}, pages = {{1411--1421}}, publisher = {{American Society of Mechanical Engineers}}, title = {{{Development of Self-Optimizing Systems.
