We numerically investigate the impact of nonlinear effects in mode-multiplexed transmission over a 50 μm graded-index multimode fiber. Such a fiber supports 36 spatial modes, well suited for a mode-multiplexed transmission. The number of mode groups used for transmission is subsequently increased to identify the nonlinear penalty occurring due to the Kerr-effect-based nonlinear interaction between the spatial modes. It is shown that the nonlinear penalty scales less than proportional with the...
The most commonly used automotive immunity test methods for electrical interferences from narrowband radiated electromagnetic energy are described in ISO 11452 series. Bulk Current Injection (BCI) and Absorber Line Shielded Enclosure (ALSE) apply different coupling mechanisms to assess the immunity of electronic components. While ALSE subjects the entire test setup to the electromagnetic fields generated by an antenna, BCI induces the interference signals directly into a certain part of the w...
Diese Arbeit konzentriert sich auf die Anwendung von Klassifikatoren um die subjektiv wahrgenommene Qualität von virtuellen Head-up-Display Bildern (HUD) in Luxusklassefahrzeugen zu beurteilen. Klassifikation versucht ausgehend von Trainingsdaten Muster bzw. Gesetzmäßigkeiten einer Aufgabenstellung zu erlernen und anschließend unbekannte Daten der gleichen Aufgabenstellung zu beurteilen. Die für diese Arbeit notwendigen HUD-Bilder werden mithilfe eines bestehenden Laboraufbaus der Daimler AG...
Although many researchers try to improve the level of machine intelligence, there is still a long way to achieve intelligence similar to what humans have. Scientists and engineers are continuously trying to increase the level of smartness of the modern technology, i.e. smartphones and robotics. Humans communicate with each other by using the voice and gestures. Hence, gestures are essential to transfer the information to the partner. To reach a higher level of intelligence, the machine should...
