This book was released on 2014 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Modern building codes require the evaluation of a shear wave velocity profile of the foundation soils for a dynamic analysis of structures and sites to occur. Wave velocities are typically evaluated by conducting laboratory and field tests. Due to the rapid pace of development in the UAE,consultants often rely on shear wave velocity (VS) obtained from correlations of shear wave velocity (VS) with N values from Standard Penetration Tests (SPT). Significant variations in previous studies that predict wave velocities justifythis new study in order to develop correlations specific to the region and applicable to areas of similar geology. These variations can be attributed to factors such as biases in conducting field tests and shortcomings in seismic techniques. This study presents the correlations developed between wave velocity and N values for the city of Sharjah by performing seismic tests in various locations. The velocity profiles are evaluated by using vertical geophones that are traditionally used, as well as, horizontal geophones to evaluate their ability in calculating similar profiles. The analysis of surface waves for velocity evaluation is preferred due to its ability in delineating hidden layers of weaker velocities and for the better characterization of shallow depths from the generation of higher frequency phases. The benefits of using a seismic technique based on surface waves are presented and the results of the regression of VS-N pairs are compared with the findings of previous studies discussed here. The effect of using horizontal and vertical geophones on the results is evaluated in order to validate the theoretical basis of particle motion during the propagation of surface waves. The results indicate many previous models underestimate the wave velocity as function of N valuesas compared to the proposed model, especially at N values larger than 15. Most recent studies, however, tend to agree with the prediction model of this study;only one model significantly overestimates the shear wave velocity. The velocity profiles computed from horizontal and vertical geophones agree, indicating that the theoretical basis of elliptical particle motion with both horizontal and vertical components in the propagation of surface waves is valid.

This book was released on 2008 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: We continued the operation of the Southern Methodist University-Institute of Geophysics, China Earthquake Administration (SMU-IGPCEA) broadband seismic network through May 2008 using Program for the Array Seismic Studies of the Continental Lithosphere (PASSCAL) instrumentation. The operating network included three stations northwest of Beijing and 10 stations in Xiuyan. Lisoning Province, NE China. At the end of May, the PASSCAL instrumentation was returned to the U.S. During the 5.5-year operation, we collected approximately 600 Gb of miniSEED data. Most of the data have been archived at the Incorporated Research Institutes for Seismology (IRIS) data center. This high-quality dataset has already provided us the opportunity to study the detailed velocity structure beneath the Huailai Basin and Haicheng in NE China using both teleseismic and regional signals. We are expanding our joint inversion of teleseismic receiver functions and surface wave phase velocities for crustal shear velocity structure from the Huailai Basin to the Huabei area using data from SMU-IGPCEA broadband seismic network with additional data provided by 48 broadband seismic stations in this region.

This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In the present dissertation, I describe two studies of the regional upper mantle shear wave velocity structure. In order to derive the absolute velocity structure of the upper mantle, I have applied surface wave tomography to model Rayleigh wave phase velocities as a function of period. Then I inverted the Rayleigh phase velocities to obtain shear wave velocities as a function of depth. The resulted high-resolution 3-D shear wave velocity model of the regional upper mantle is characterized by a better depth resolution than any preexisting tomographic models. I also conducted a shear wave splitting analysis using traditional methods and developed a two-layer grid search algorithm in order to infer the upper mantle anisotropic structure. The results of the shear wave splitting analysis for the stations located in Azerbaijan are the first in the region. My 3-D velocity model shows the depth extent of the asthenospheric layer beneath the Turkish and Iranian Plateaus, which does not exceed 200 km and therefore rejects any suggestions of the existence of deep mantle plums in the area. The deep high velocity bodies beneath the Black Sea and northern Iranian Plateau are identified as the remnant slabs of the northern and southern brbranchesf the Neo-Tethys lithosphere. The widespread volcanism and the uplift within the plateau were the result of a gradual steepening of the subducting slab of the southern branch of Neo-Tethys. The shear wave splitting analysis shows evidence of the two-layer anisotropic structure beneath the eastern Caucasus region. The results presented in the dissertation are crucial for the regional seismic hazard analysis.

This book was released on 2013-11-21 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and dis seminated by the Center for lnformation and Numerica/ Data Analysis and Synthesis (C/NDAS) * at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the ac tivity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficia! to the academic and general scientific and technical community. After fi ve years of this joint undertaking we had concluded that it was in the interest of ali concerned if the printing and distribution of the volume were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and App/ied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. Ali back issues can also be ordered from Plenum. We have reported in Volume 21 (thesis year 1976) a total of 10,586 theses titles from 25 Canadian and 219 United States universities. We are sure that this broader base for theses titles reported will greatly enhance the value of this important annual reference work.
