@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. Die Anzahl zu animierender Objekte ist in komplexen Modellen zu groß, um alle Animationen flüssig darzustellen. Dynamisch abgestuft wählt das entwickelte Verfahren gezielt wichtige Animationen aus, weniger relevante Animationen werden entsprechend seltener animiert. Die Selektion der Animationen erfolgt nach der projizierten Größe der Objekte auf das Ausgabegerät, um einen guten optischen Eindruck beizubehalten. Angepasst an die Leistungsfähigkeit des Rechners wird das Verfahren so geregelt, dass die Visualisierung einer hohen Anzahl von Objekten in Echtzeit möglich bleibt. Das Verfahren ist in einem Editor prototypisch implementiert, mit dem Schlüsselbilder für Objekte erzeugt werden können. Das Gruppieren von Objekten wird erlaubt, so dass eine Hierarchie von Bewegungspfaden definierbar ist. Die Evaluierung der Methode wird mittels Testszenen durchgeführt, die aus mehreren zehntausend animierten Objekten bestehen.}}, author = {{Laroque, Christoph and Fischer, Matthias and Eikel, Benjamin}}, booktitle = {{Augmented & Virtual Reality in der Produktentstehung}}, pages = {{193----206}}, publisher = {{Verlagsschriftenreihe des Heinz Nixdorf Instituts, Paderborn}}, title = {{{Regelung von Animationen in Simulationen von hochdynamischen Fabrikszenen }}}, volume = {{232}}, 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{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{23256, author = {{Münch, Eckehard and Adelt, Philipp and Krüger, Martin and Kleinjohann, Bernd and Trächtler, Ansgar}}, booktitle = {{Proceedings of the International Conference on Control, Automation and Systems (ICCAS)}}, title = {{{Hybrid Planning and Hierarchical Optimization of Mechatronic Systems}}}, year = {{2008}}, } @article{23259, author = {{Voecking, Henner and Trächtler, Ansgar}}, journal = {{International Conference on Control, Automation and Systems 2008 (ICCAS)}}, pages = {{14--17}}, title = {{{Self-optimization of an Active Suspension System Regarding Energy Requirements}}}, year = {{2008}}, } @inproceedings{23264, author = {{Geisler, Jens and Witting, Katrin and Trächtler, Ansgar and Dellnitz, Michael}}, booktitle = {{Proc. 17th IFAC World Congress}}, title = {{{Multiobjective Optimization of Control Trajectories for the Guidance of a Rail-bound Vehicle}}}, year = {{2008}}, } @article{23270, author = {{Geisler, Jens and Witting, Katrin and Trächtler, Ansgar and Dellnitz, Michael}}, journal = {{7th International Heinz Nixdorf Symposium: Self-optimizing Mechatronic Systems: Designing the Future}}, title = {{{Self-Optimization of the Guidance Module of a Rail-bound Vehicle}}}, year = {{2008}}, } @inproceedings{9573, abstract = {{Integrating dependability in self-optimizing systems is a challenging task.

Convergence is measured by the performance indicators Generational Distance, Spread and Hypervolume. The stochastic nature of the MOEA is taken into account by repeated runs per generation number which results in a highly robust procedure. For each generation number the MOEA is repeated a fixed number of times, and the Kolmogorow-Smirnov-Test is used in order to decide if a significant change in performance is gained in comparison to preceding generations. A comparison of different MOEAs on a problem with respect to necessary generation numbers becomes possible, and the understanding of the algorithm’s behaviour is supported by analysing the development of the indicator values.

We investigated the effect of extracellular proteases on rat ENaC heterologously expressed in Xenopus laevis oocytes. Application of trypsin increased ENaC whole-oocyte currents by about 8-fold without a concomitant increase in channel surface expression. The stimulatory effect of trypsin was preserved in oocytes expressing alphagamma-ENaC, but was abolished in oocytes expressing alphabeta-ENaC. Thus, the gamma-subunit appears to be essential for channel activation by extracellular proteases. Site-directed mutagenesis of a putative prostasin cleavage site in the extracellular loop of the gamma-subunit revealed that mutating the 181Lys residue to alanine (gammaK181A) increases ENaC baseline whole-oocyte currents, decreases channel surface expression, and largely reduces the stimulatory effect of extracellular proteases (trypsin, chymotrypsin and human neutrophil elastase). In single-channel recordings from outside-out patches we demonstrated that the gammaK181A mutation essentially abolishes the activation of near-silent channels by trypsin, while a stimulatory effect of trypsin on channel gating is preserved. This apparent dual effect of trypsin on channel gating and on the recruitment of near-silent channels was confirmed by experiments using the beta518C mutant ENaC which can be converted to a channel with an open probability of nearly one by exposure to a sulfhydryl reagent. Interestingly, the gammaK181A mutation results in the spontaneous appearance of a 67 kDa fragment of the gamma-subunit in the plasma membrane which can be prevented by a furin inhibitor and also occurs after channel activation by extracellular trypsin. This suggests that the mutation promotes channel cleavage and activation by endogenous proteases. This would lower the pool of near-silent channels and explain the constitutive activation and reduced responsiveness of the mutant channel to extracellular proteases. We conclude that the mutated site (K181A) affects a region in the gamma-subunit of ENaC that is functionally important for the activation of near-silent channels by extracellular proteases.}}, author = {{Diakov, Alexei and Bera, Katarzyna and Mokrushina, Marianna and Krueger, Bettina and Korbmacher, Christoph}}, journal = {{The Journal of Physiology}}, number = {{19}}, pages = {{4587–4608}}, publisher = {{Wiley}}, title = {{{Cleavage in the γ-subunit of the epithelial sodium channel (ENaC) plays an important role in the proteolytic activation of near-silent channels}}}, doi = {{10.1113/jphysiol.2008.154435}}, volume = {{586}}, year = {{2008}}, } @inproceedings{2372, author = {{Schumacher, Tobias and Plessl, Christian and Platzner, Marco}}, booktitle = {{Many-core and Reconfigurable Supercomputing Conference (MRSC)}}, keywords = {{IMORC, IP core, interconnect}}, title = {{{IMORC: An infrastructure for performance monitoring and optimization of reconfigurable computers}}}, year = {{2008}}, }
