A new method is presented which combines a forward and an image operator (resolution function) to construct a simulated migrated seismic section from a geological depth model. To efficiently use this tool during seismic interpretation, a fast implementation is necessary. This is achieved by improving the performance of the serial algorithm.

the presence of noise in geophysical measurements has undesirable effects on the seismic data. one of the important problems in seismic data processing is attenuation of the noise to the desired form and keeping the original signal. contamination of seismic data with noise prevents obtaining a proper image of geological structures and seismic data interpretation. in some of the receivers the no...

The seismic performance assessment of buildings is a challenging process [...]

Computerized seismic prospecting is an echo-ranging technique usually targeted at accurate mapping of oil and gas reservoirs. In seismic surveys an impulsive source, often an explosive charge, located at the earth's surface generates elastic waves which propagate in the subsurface; these waves are scattered by the earth's geological discontinuities back to the surface, where an array of receive...

The earthquake engineering community recognizes the need to improve current seismic codes and design methods in the light of recent inadequate behavior of building structures. Presently, the performance-based earthquake engineering is being envisioned as the solution to this problem. In this new design approach, the desired behavior of the building is formulated first in the conceptual stage fo...

In this paper an optimization framework is presented for automated performance-based seismic design of bridges consisting of multi-column RC pier substructures. The beneficial effects of fusing components on seismic performance of the quasi-isolated system is duly addressed in analysis and design. The proposed method is based on a two-step structural analysis consisting of a linear modal dynami...

Recent works have shown that GenLOT coding is a very effective technique for compressing seismic data. The role of a transform in a coder is to concentrate information and reduce statistical redundancy. When used with embedded zerotree coding, GenLOTs often provide superior performance to traditional block oriented algorithms or to wavelets. In this work we investigate the use of Generalized Un...
