Design &implementation of complex-valued FIR digital filters with application to migration of seismic data [PDF]

open access: yes, 2006
One-dimensional (I-D) and two-dimensional (2-D) frequency-space seismic migration FIR digital filter coefficients are of complex values when such filters require special space domain as well as wavenumber domain characteristics. In this thesis, such FIR

Geotechnical design with apparent seismic safety factors well-bellow 1 [PDF]

open access: yes, 2014
The paper demonstrates that whereas often in seismic geotechnical design it is not realistically feasible to design with ample factor of safety against failure as is done in static design, an "engineering" apparent seismic factor of safety less than 1 ...
