We have ported serial codes for 2-D and 3-D seismic depth migration to parallel platforms. The porting was done using portable parallel primitives, such that the same code can be run on a . number of parallel machines, workstation clusters, as well as serial machines. Only small modifications of the serial codes were necessary. Efficient parallel codes were obtained with moderate modification o...

The fundamental period of vibration appears to be one of the most critical parameters for the seismic design of buildings because it strongly affects the destructive impact of the seismic forces. In this article, important research data (entitled FP4026 Research Database (Fundamental Period-4026 cases of infilled frames) based on a detailed and in-depth analytical research on the fundamental pe...

This paper investigates the applicability as wel{ as the accuracy of artificial neural networks for estimating specific parameters that describe reservoir properties based on seismic data, Our approach relies on JPL’s adjoint operators general purpose neural network code to determine the best suited architecture, We believe that results presented l; this work demonstrate that artificial neural ...

For optimization of real-world arch dams, it is unavoidable to consider two or more conflicting objectives. This paper employs two multi-objective differential evolution algorithms (MoDE) in combination of a parallel working MATLAB-APDL code to obtain a set of Pareto solutions for optimal shape of arch dams. Full dam-reservoir interaction subjected to seismic loading is considered. A benchmark ...

17 run-up algorithm. The code requires as input detailed information on seismic source mechanisms, gridded bathymetric data information for the open sea propagation, and a set of gridded Digital Elevation Models (DEM) containing bathymetry and topography for use during the inundation phase. Accurate bathymetry and topography data for Rhodes were purchased/collected from various sources, GIS-pro...

In the present study, ten steel-moment resisting frames (SMRFs) having different numbers of stories ranging from 3 to 20 stories and fundamental periods of vibration ranging from 0.3 to 3.0 second were optimized subjected to a set of earthquake ground motions using the concept of uniform damage distribution along the height of the structures. Based on the step-by-step optimization algorithm dev...

The paper investigates the eeective performance attainable for a speciic class of application programs on shared memory supercomputers. Speciically, we are to investigate how seismic data analysis applications behave on the Kendall Square Research Inc.'s KSR multiprocessors. The computational kernel of seismic computation algorithms is parallelized and its performance is analyzed. Three approac...
