GUI Based Computer Programs for Analyzing Dynamic Signals Detected from a Physical Earthquake Model

摘要

Many methods are available to be used as tools for data analysis, such as Fast Fourier Transform (FFT) and Hilbert Huang Transform (HHT). However, the raw data need to be pre-processed before applying those methods. To deal with considerable raw data, it should be processed in a fast and efficient way. In this research, the dynamic signal data are obtained from physical earthquake models. To process the huge amount of data is always complicated and time consuming. Customized GUI programs to pre-process and post-process data has been designed to make the raw signal data express its physical meaning rapid by a combination of the manual and automatic process. The research uses animations to display the signal change in time that the signal detected can be shown by a graph which is close to physical phenomena and makes the physical data meaning become more obvious.
