The simulator is written in Java, is event-based and mainly used in p2p research projects. The main development of PeerfactSim.KOM started in 2005 and is driven since 2006 by the project “QuaP2P”,which aims at the systematic improvement and benchmarking of p2p systems. Further users of the simulator are working in the project “On-the-fly Computing” aiming at researching p2p-based service oriented architectures.

Both algorithms have been designed with a strong emphasis on applicability in the area of wireless sensor networks: in order to execute them, each sensor node only requires limited local knowledge and simple computations. Also, the algorithms can cope with measurement errors and take into account that communication costs between sensor nodes do not necessarily increase linearly with the distance, but can be represented by a polynomial. Since it cannot always be expected that sensor nodes execute algorithms in a synchronized way, our algorithms are executed in an asynchronous model (but they are still able to break symmetry that might occur when two neighboring nodes act at exactly the same time). Furthermore, they can deal with dynamic scenarios: if a node moves, the solution is updated and the update affects only nodes in the local neighborhood. Finally, the algorithms are robust in the sense that incorrect behavior of some nodes during some round will, in the end, still result in a good approximation. The first algorithm runs in expected O(log_{1+\epsilon} n) communication rounds and yields a \my^4(1+4\my^2(1+\epsilon)^{1/p})^p approximation, while the second has a running time of expected O(log^2_{1+\epsilon} n) communication rounds and an approximation factor of \my^4(1 + 2(1 + \epsilon)^{1/p})^p. Here, \epsilon > 0 is an arbitrarily small constant, p the exponent of the polynomial representing the communication costs, and \my the relative measurement error.}}, author = {{Abshoff, Sebastan and Cord-Landwehr, Andreas and Degener, Bastian and Kempkes, Barbara and Pietrzyk, Peter}}, booktitle = {{Proceedings of the 7th International Symposium on Algorithms for Sensor Systems, Wireless Ad Hoc Networks and Autonomous Mobile Entities (ALGOSENSORS)}}, pages = {{13--27}}, title = {{{Local Approximation Algorithms for the Uncapacitated Metric Facility Location Problem in Power-Aware Sensor Networks}}}, doi = {{10.1007/978-3-642-28209-6_3}}, year = {{2011}}, } @inproceedings{662, abstract = {{We present Corona, a deterministic self-stabilizing algorithm for skip list construction in structured overlay networks.

These two kinds of distortion alter the shape of the feature vector trajectory extracted from the microphone signal and consequently lead to a discrepancy between training and testing conditions for the recognizer. In this chapter we present a feature enhancement approach aiming at the joint compensation of noise and reverberation to improve the performance by restoring the training conditions. For the enhancement we concentrate on the logarithmic mel power spectral coefficients as features, which are computed at an intermediate stage to obtain the widely used mel frequency cepstral coefficients. The proposed technique is based on a Bayesian framework, to attempt to infer the posterior distribution of the clean features given the observation of all past corrupted features. It exploits information from a priori models describing the dynamics of clean speech and noise-only feature vector trajectories as well as from an observation model relating the reverberant noisy to the clean features. The observation model relies on a simplified stochastic model of the room impulse response (RIR) between the speaker and the microphone, having only two parameters, namely RIR energy and reverberation time, which can be estimated from the captured microphone signal. The performance of the proposed enhancement technique is finally experimentally studied by means of recognition accuracy obtained for a connected digits recognition task under different noise and reverberation conditions using the Aurora~5 database.}}, author = {{Krueger, Alexander and Haeb-Umbach, Reinhold}}, booktitle = {{Robust Speech Recognition of Uncertain or Missing Data}}, editor = {{Haeb-Umbach, Reinhold and Kolossa, Dorothea}}, publisher = {{Springer}}, title = {{{A Model-Based Approach to Joint Compensation of Noise and Reverberation for Speech Recognition}}}, year = {{2011}}, } @article{16013, author = {{Lauter, Christian and Frantz, Meike and Tröster, Thomas}}, issn = {{1865-4819}}, journal = {{Lightweight Design}}, pages = {{48--54}}, title = {{{Großserientaugliche Herstellung von Hybridwerkstoffen durch Prepregpressen}}}, doi = {{10.1365/s35725-011-0044-5}}, volume = {{4}}, year = {{2011}}, } @inproceedings{13053, author = {{Cook, Alejandro and Hellebrand, Sybille and Indlekofer, Thomas and Wunderlich, Hans-Joachim}}, booktitle = {{5.
