Various approached have been introduced to extract as much as information form seismic image for any specific reservoir or geological study. Modeling of faults and fractures are among the most attracted objects for interpretation in geological study on seismic images that several strategies have been presented for this specific purpose. In this study, we have presented a modified approach of ap...

the seismic performance of hybrid braces composed of steel and shape memory alloy (sma) was investigated in this paper. six types of hybrid braces were used, constituted by sma content of 0, 20, 40, 60, 80, and 100%. a nonlinear dynamic analysis was performed under el centro earthquake records, with the maximum acceleration of 0.6g and 0.9g. our results showed that the seismic performance, i.e....

results of velocity structure modeling in the earth's crust using a comparison approach of receiver function analysis and joint inversion of receiver functions with surface wave dispersion data are presented in this paper. seismograms of the teleseismic events that have been recorded on a broadband seismic station in the central alborz were used for data processing. velocity models that we...

this paper describes a methodology for the integration of well logs and a series of grid-based attributes extracted from interpreted seismic data for prediction of porosity distributions. the studied area is located in the southwest iran. before finding a relationship between the target logs and predicted logs from 3d seismic data, we have interpreted the 3d seismic data in the studied area. al...

Coastal Fars gravimetry project in Fars province was carried out to find the buried salt domes and to determine characteristics of faults in this area. The Lavarestan structure was covered by 4203 gravimetry stations in a regular grid of 1000*250 m. Depth structural model of this anticline made in previous studies was based on geological evidences and structural geology measurements. In order t...

The article presents the main provisions of modeling multi-story buildings with seismic isolation, characteristics isolation device, structural elements and materials, methodology for conducting experimental studies on a laboratory vibro-stand under dynamic (seismic) effects results modeling.

1. Related work. A general linear self-exciting process is identified by the conditional intensity function λ(t) = µ + k 0 t k <t g(t − t k) where µ is the baseline hazard rate. The Hawkes Process (Hawkes, 1971a,b) is a particularly tractable self-exciting point process with an exponential kernel, developed for earthquake modeling. Historically, a lot of effort has gone into modeling earthquake...

This dissertation consists of four research topics, addressing three different scales of crustal-scale seismic data analysis. At the large scale, this research involves determining the lithospheric crustal structure across the southern Rio Grande rift (SRGR) from a 205 km long refraction/wide-angle reflection profile across southern New Mexico into Far West Texas acquired during the Portillo Vo...

We proposed an economic, cost-constrained optimal design of a water distribution system (WDS) that maximizes seismic reliability while satisfying pressure constraints. The model quantifies the seismic reliability of a WDS through a series of procedures: stochastic earthquake generation, seismic intensity attenuation, determination of the pipe failure status (normal, leakage, and breakage), pipe...
