It brought about great success in the past few years regarding the evaluation of deterministic two-player games such as the Asian board game Go. In this thesis, we present a parallelization of the most popular MCTS variant for large HPC compute clusters that efficiently shares a single game tree representation in a distributed memory environment and scales up to 128 compute nodes and 2048 cores. It is hereby one of the most powerful MCTS parallelizations to date. In order to measure the impact of our parallelization on the search quality and remain comparable to the most advanced MCTS implementations to date, we implemented it in a state-of-the-art Go engine Gomorra, making it competitive with the strongest Go programs in the world. We further present an empirical comparison of different Bayesian ranking systems when being used for predicting expert moves for the game of Go and introduce a novel technique for automated detection and analysis of evaluation uncertainties that show up during MCTS searches.}}, author = {{Schäfers, Lars}}, isbn = {{978-3-8325-3748-7}}, pages = {{133}}, publisher = {{Logos Verlag Berlin GmbH}}, title = {{{Parallel Monte-Carlo Tree Search for HPC Systems and its Application to Computer Go}}}, year = {{2014}}, } @inproceedings{11996, author = {{Eckert, Juergen and Sommer, Christoph and Eckhoff, David}}, booktitle = {{Proceedings of the 11th ACM symposium on Performance evaluation of wireless ad hoc, sensor, & ubiquitous networks - PE-WASUN '14}}, isbn = {{9781450330251}}, title = {{{Towards a simulation framework for paraglider networks}}}, doi = {{10.1145/2653481.2655754}}, year = {{2014}}, } @inproceedings{15090, author = {{Böttcher, Stefan and Brandenburg, Marc and Hartel, Rita}}, booktitle = {{Proceedings of the Second Australasian Web Conference}}, pages = {{13--20}}, publisher = {{Australian Computer Society, Inc.}}, title = {{{Keyword Search on DAG-Compressed XML Data}}}, year = {{2014}}, } @inproceedings{15092, author = {{Böttcher, Stefan and Hartel, Rita and Rabe, Jonathan}}, booktitle = {{Database and Expert Systems Applications - 25th International Conference, DEXA 2014}}, isbn = {{9783319100722}}, issn = {{0302-9743}}, pages = {{122--137}}, publisher = {{Springer}}, title = {{{Efficient XML Keyword Search Based on DAG-Compression}}}, doi = {{10.1007/978-3-319-10073-9_11}}, year = {{2014}}, } @inproceedings{16120, author = {{Block, Holger and Marten, Thorsten and Tröster, Thomas}}, location = {{Braunschweig}}, title = {{{Crash simulation of high strength automotive components using advanced failure models}}}, year = {{2014}}, } @inproceedings{16129, author = {{Reuter, Corin and Flore, Dominik and Pöhler, Simon and Sauerland, Kim Henning and Tröster, Thomas}}, location = {{Leipzig}}, title = {{{Numerical simulation of the energy absorption of fiber-reinforced plastics}}}, year = {{2014}}, } @inproceedings{13878, author = {{Bause, Fabian and Schroder, Andreas and Rautenberg, Jens and Henning, Bernd and Gravenkamp, Hauke}}, booktitle = {{2014 IEEE International Ultrasonics Symposium}}, isbn = {{9781479970490}}, title = {{{Time-causal material modeling in the simulation of guided waves in circular viscoelastic waveguides}}}, doi = {{10.1109/ultsym.2014.0333}}, year = {{2014}}, } @inproceedings{13944, author = {{Bause, Fabian and Weber, Daniel and Rautenberg, Jens and Henning, Bernd}}, isbn = {{9783800736225}}, location = {{Nürnberg}}, publisher = {{{VDE Verlag}}}, title = {{{Unsicherheitsanalyse eines Vorwärtsmodells zur Simulation transienter Wellenausbreitung im Hohlzylinder}}}, year = {{2014}}, } @inproceedings{24305, abstract = {{Energy efficiency drives the development of more and more complex low-power designs. Based on dynamic power management techniques, multiple voltage islands as well as a huge amount of power states are specified that have to be tested carefully. In this context, low-power design should start at an early stage using state-of-the-art system-level modeling and simulation techniques. However, there is neither a programming language nor any modeling standard that reflects variable power together with its functional side effects in a well-suited abstract manner. To overcome this limitation, we present a modeling approach on top of SystemC TLM to capture low-power design characteristics at electronic system-level. We demonstrate the usability by means of an existing open-source low-power design.

Furthermore, lightweight parts with specific inner core structures can be manufactured in order to achieve good weightrelated strength properties.

Therefore, test specimens with known lightweight core geometries (e.g. corrugated and honeycomb cores) were designed. A four-point bending test was conducted to analyze the strength properties as well as the weight-related strength properties. Additionally the influence of the structure width, the structure wall thickness and the top layer thickness was analyzed using a honeycomb structure.}}, author = {{Bagsik, A. and Josupeit, S. and Schöppner, Volker and Klemp, E.}}, booktitle = {{29th International Conference of the Polymer Processing Society}}, pages = {{696--701}}, publisher = {{American Institute of Physics }}, title = {{{Mechanical Analysis of Lightweight Constructions manufactured with Fused Deposition Modeling}}}, doi = {{10.1063/1.4873874}}, volume = {{29}}, year = {{2014}}, } @article{34442, abstract = {{Radial shaft seals are used in a variety of applications, where rotating shafts in steady housings have to be sealed. Typical examples are crankshafts, camshafts, differential gear or hydraulic pumps. In the operating state the elastomeric seal ring and the shaft are separated by a lubrication film of just a few micrometers. Due to shear strain and fluid friction the contact area is subject to a higher temperature than the rest of the seal ring. The stiffness of the elastomeric material is intensely influenced by this temperature and thus contact pressure, friction and wear also strongly depend on the contact temperature. In order to simulate the contact behavior of elastomer seal rings it is essential to use a comprehensive approach which takes into consideration the interaction of temperature, friction and wear. Based on this idea a macroscopic simulation model has been developed at the MEGT. It combines a finite element approach for the simulation of contact pressure at different wear states, a semi-analytical approach for the calculation of contact temperature and an empirical approach for the calculation of friction.
