This presentation discusses the advantages and limitations of using Dynamic Time Warping (DTW) to quantify the similarity between measurements of different weldings. In this project, machine vibrations and airborne sound occurring during Ultrasonic sheet Metal Welding are recorded, using two laser Doppler vibrometers and a microphone. The goal of the project is to get a better understanding of the processes that occur during […]

This talk will address the musical blind source separation problem: given multiple instrument tracks recorded together, how can each be isolated from the others given no additional knowledge about the instrument locations or sounds? There are many advantages to solving the problem: live performances can convey the energy of the performers, and the sound of […]

Auralizations of simulationed aircraft flyovers can be used to experience aircraft noise in virtual environments. Compared to averaged sound pressure levels or noise maps, listening to such an auralization provides a more sophisticated impression on how annoying the aircraft noise might be in a real scenario. For proper auralization results, the inhomogeneity of the atmosphere, […]

Ultrasonic metal welding (USMW) has received significant attention in recent years. It is particularly suitable for connecting electrotechnical components and has been widely used in various industrial applications. However, the bond quality in USMW fluctuates due to a large number of influencing variables which may affect the joint strength. The welding process should thus be […]

Teaching courses online has gained importance in the recent semesters. While lectures can often be delivered in a straight forward manner, lab courses require a specific infrastructure. This talk presents how the newly introduced RWTH JupyterHub server can be used deliver a lab course experiement - that is the TI lab course as an example […]
