Wavelet Transform of Gravity Time Series in Hurbánovo
 Pénzešová, Laura
The Hurbanovo Observatory has been part of the International Geodynamics and Earth Tide Service (IGETS) since 2021 and provides measurements utilizing the gPhoneX108 spring gravimeter. In this study, a wavelet decomposition using multiple types of wavelets was performed on the gravity time series with a 1-minute step. The study was performed on the gravity measurements during the February 2023 earthquakes in Turkey and Syria. The primary objective was to eliminate the influence of seismic events in the gravity time series using wavelet transform, aiming to find a balance between maintaining long-period signal components and minimising distortion of the original signal.

Vaveletový rozklad nestacionárního náhodného signálu
 Fischer, Cyril ; Náprstek, Jiří
The paper provides a support for the wavelet based approach for the analysis of the MDOF systems subjected to non-stationary excitation. It tries to cover the lack of input data in the form of the wavelet decomposition of seismic records.
