Permutation Entropy as a Conceptual Model to Analyse Brain Activity in Sleep

no code implementations12 Dec 2023 Alexander Edthofer, Iris Feldhammer, Thomas Fenzl, Andreas Körner, Matthias Kreuzer

This results in a time discrete signal, that can be further processed by applying the method of permutation entropy, which is a modification of the Shannon entropy as a measure of information processing.

Novel features for the detection of bearing faults in railway vehicles

no code implementations14 Apr 2023 Matthias Kreuzer, Alexander Schmidt, Walter Kellermann

However, these features are usually evaluated on data originating from relatively simple scenarios and a significant performance loss can be observed if more realistic scenarios are considered.

Audio Signal Processing Fault Detection

Airborne Sound Analysis for the Detection of Bearing Faults in Railway Vehicles with Real-World Data

no code implementations14 Apr 2023 Matthias Kreuzer, David Schmidt, Simon Wokusch, Walter Kellermann

In this paper, we address the challenging problem of detecting bearing faults in railway vehicles by analyzing acoustic signals recorded during regular operation.
