    Performance comparison of TwinCat ADS for Python and Java
    (Softwaretechnik-Trends Band 43, Heft 4, 2023) Weber, Alexander; Eichelberger, Holger; Schreiber, Per; Wienrich, Svenja
    Real-time and in-process measurements are important in the manufacturing domain, e.g., for real-time process monitoring. For performance reasons, such data is often processed in virtualized environments on edge devices, as e.g., provided by the company Beckhoff. For exploring modern AI methods, integration with high-level languages such as Python or even with Industry 4.0 platforms for advanced data flows is needed. In this paper, we analyze the read/write perfor mance of a Beckhoff device integrated via Python or Java. For our experiments, we use a simulation on a PC as well as a networked setup with a Beckhoff device. We show that the Java-based solution is faster than the Python one by 2-3 times. We also show that small arrays can be read as fast as a single value, that there is no difference between operations for small or big data types and that there is no difference between reading and writing data.

    Real-Time MIR Algorithms for Music-Reactive Game World Generation
    (Mensch und Computer 2022 - Workshopband, 2022) Meier, Peter; Schwär, Simon; Rosenzweig, Sebastian; Müller, Meinard
    In music education, an important learning objective is to acquire a sense of rhythm and melody, e.g., by tapping or singing along to a musical performance. In this context, music games are becoming increasingly popular due to their accessibility and interactivity. However, existing games are often tailored to a specific musical repertoire. In this paper, we will explore the potential of music information retrieval (MIR) algorithms for generating dynamic game worlds that are reactive to musical input in real-time, e.g., to music from a stereo system or a live performance. Such games may be used to explore musical performances in an interactive and playful way. As a case study, we therefore developed a jump-andrun game prototype that challenges players to tap along the beat of the music in their environment. Its music-reactive game world relies on past and predicted beat positions estimated by a real-time beat tracking algorithm.
