Abstract: Determination of the source time function and earth impulse response for explosive source seismic reflection data is traditionally performed using predictive deconvolution, which assumes the reflection seismogram is the convolution of a minimum-phase wavelet with… read more here.

DOI: 10.1785/0220240161
Abstract: Predicting an earthquake’s final magnitude from its initial characteristics is of fundamental importance for earthquake physics and practical applications such as early warning systems. However, past research presents conflicting views on using initial rupture characteristics… read more here.

DOI: 10.3390/sym16070864
Abstract: In this paper, an inverse problem of determining a source in a time-fractional diffusion equation is investigated. A Fourier extension scheme is used to approximate the solution to avoid the impact on smoothness caused by… read more here.
