Research shows that training environments that adapt to users' preferences and performance can promote more effective learning. However, the observed results can hardly be traced back to specific adaptive measures but the whole new training approach. This study analyzes the effects of a combined point and leveling VR-based gamification system on assembly training targeting specific training outcomes and users' motivations. The Gamified-VR-Group with 26 subjects received the gamified training, and the Non-Gamified-VR-Group with 27 subjects received the alternative without gamified elements. Both groups conducted their VR training at least three times before assembling the actual structure. The study found that a level system that gradually increases the difficulty and error probability in VR can significantly lower real-world error rates, self-corrections, and support usages. According to our study, a high error occurrence at the highest training level reduced the Gamified-VR-Group's feeling of competence compared to the Non-Gamified-VR-Group, but at the same time also led to lower error probabilities in real-life. It is concluded that a level system with a variable task difficulty should be combined with carefully balanced positive and negative feedback messages. This way, better learning results, and an improved self-evaluation can be achieved while not causing significant impacts on the participants' feeling of competence.}, language = {en} } @article{DuesGebhardtKallweitetal.1994, author = {Dues, M. and Gebhardt, Andreas and Kallweit, Stephan and Scheffler, T. and Siekmann, H. and Uchiyama, T.}, title = {Flow Visualization in a Cavitating Flow}, series = {Proceedings of the German-Japanese Symposium on Multi-Phase Flow : Karlsruhe, Germany, August 23 - 25, 1994 / comp. by U.

A high-resolution finite element model was created directly from the available design documents. All physical properties of the structural components were included in detail, so no calibration to the measured data was necessary. The deck and towers were modeled with shell elements. A nonlinear static analysis was performed before the eigenvalue calculation. The calculated natural frequencies and corresponding mode shapes showed good agreement with the available measured ambient vibration data. The calculation of the effective modal mass showed that nine modes had single contributions higher than 5 \% of the total mass. They were in a frequency range up to 1.2 Hz. The comparison of the results for the torsional modes especially demonstrated the advantage of using thin shell finite elements over the beam modeling approach.}, language = {en} } @article{KallweitUchiyamaSiekmann1998, author = {Kallweit, Stephan and Uchiyama, R. and Siekmann, H.}, title = {Fault Diagnostic Method for Pump Running Conditions Based on Process Modeling and Neural Network / Uchiyama, R. ; Kallweit, S. ; Siekmann, H.}, series = {International Journal of Rotating Machinery. 4 (1998), H. 1}, journal = {International Journal of Rotating Machinery. 4 (1998), H. 1}, isbn = {1542-3034}, pages = {49 -- 59}, year = {1998}, language = {en} }
