Book excerpt: The University of Missouri-Rolla acquired multi-channel surface wave (Rayleigh wave) seismic data along a 6400 ft segment of Interstate I-70 in downtown St. Louis, Missouri. The acquired surface wave data set was processed [multi-channel analysis of surface waves (MASW)] and transformed into a 2-D MASW shear-wave velocity profile with a station-spacing of 40 ft. The interpreted depth to bedrock along the length of the 2-D profile varies between 20 ft and 44 ft. Geotechnical data provided by the Missouri Department of Transportation and presented herein indicates the interpreted 2-D MASW shear-wave velocity profile correlates well with available bedrock (borehole) and seismic cone penetrometer control, supporting the conclusion that the MASW technique can be used to generate reliable 2-D shear-wave velocity profiles.

This book was released on 2003 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: Surface wave (Rayleigh wave) seismic data were acquired at six separate bridge sites in southeast Missouri. Each acquired surface wave data set was processed [spectral analysis of surface waves (SASW)] and transformed into a site-specific vertical shear-wave velocity profile (SASW shear-wave velocity profile). The SASW shear-wave velocity profiles generated for each bridge site were compared to other geotechnical data including seismic cone penetrometer shear-wave velocity profiles, cross-borehole shear-wave velocity profiles, and borehole lithology logs. The geotechnical data presented herein indicate the SASW shear-wave velocity profiles correlate well with subsurface lithology logs and available cross-borehole shear-wave velocity control. More specifically, clays, silts and sands exhibit relatively characteristic SASW shear-wave velocities, which increase incrementally with increasing depth of burial. The authors believe these correlations demonstrate that SASW shear-wave velocities are reliable.

This book was released on 2015 with total page 131 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Multichannel Analysis of Surface Waves (MASW) and Electrical Resistivity Tomography (ERT) data were acquired in the Newburg, Missouri with the goal of determining optimum MASW acquisition parameters. Users of the MASW tool generally state that greater geophone intervals and greater shot-to-receiver offsets provide for more accurate results. The objective was to determine if this "rule of thumb" applies in karst terrain. ERT data were acquired along four traverses with eighty-four (84) electrodes at five feet spacing with SuperSting R8 Resistivity System using dipole- dipole array. The data were processed using Earth Imager to generate 2-D resistivity inversion and thereafter, Voxler software was used to collate the 2-D ERT data into a 3-D resistivity model. MASW data on the other hand, were acquired along the same ERT traverses on the same locations using a suite of different geophone intervals (1-ft, 2.5-ft, 5-ft, 7.5-ft, and 10-ft) and shot-to-receiver spacings (0-ft, 10-ft, 20-ft, 30-ft, 40-ft, and 50-ft) with a 20lb sledge hammer as the source. The data were processed using Surfseis software to generate the dispersion curves and 1-D shear wave velocity profiles of the area. On the basis of the comparative analyses of the ERT and MASW data, it was determined that 2.5-ft and 5-ft geophone gave generated depth of bedrock that was consistent with ERT data. With 5-ft geophone spacing it is possible to image the subsurface to greater depth, but with the 7.5-ft and 10-ft, unidentifiable dispersion curves would be generated. Therefore, in this study area, on the basis of data that were acquired it is recommended that 2.5ft spacing be used if depth of investigation is about 40ft, but if the depth of investigation is about 80-ft, using a sledge hammer source then 5-ft geophone spacing at 20-ft shot-receiver offset distance is recommended."--Abstract, page iii.

Available in PDF, EPUB and Kindle. Book excerpt: With minimal simplifying assumptions and approximations, an automated version of the spectral analysis of surface waves (SASW) method has been developed to determine in situ shear wave velocity profiles of soil deposits. Testing time for each site, including collection of data, construction and inversion of dispersion curve, should not be more than thirty minutes. To accelerate field testing, a multi-sensor geophone array and a PC-based data-acquisition, signal-analysis package have been developed. The two greatest challenges have been the development of a fully-automated procedure to construct the dispersion curve from field data and a fast yet, theoretically-sound, inversion process to determine the shear wave velocity profile from a given dispersion curve. In this paper, the major theoretical and practical aspects of these two steps are described and discussed with examples.

This book was released on 2017 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: Deep (typically >1000 m) shear wave velocity profiles were developed across the Canterbury basin at nine strong motion stations using a combination of active and passive surface wave methods and horizontal to vertical spectral ratio measurements. A multi-mode, multi-method joint inversion process, which included Rayleigh and Love wave dispersion and horizontal to vertical spectral ratio data, was used to estimate the shear wave velocity profiles at each site. A-priori geologic information was utilized in defining preliminary constraints on the complex geologic layering of the Canterbury basin. At sites where interbedded layers were present, velocity reversals were considered in the inversion. Shear wave velocity profiles developed as part of this study were combined with the median profiles from 14 Christchurch sites detailed in a separate study, to develop a suite of region and soil specific reference shear wave velocity profiles for the Canterbury basin. Site specific and reference shear wave velocity profiles developed as part of this study can be used for back-analysis of earthquake ground motions, forward analysis of future ground motions, full 3D physics based simulations, or to refine 3D velocity models for the region. 1000 m) shear wave velocity profiles were developed across the Canterbury basin at nine strong motion stations using a combination of active and passive surface wave methods and horizontal to vertical spectral ratio measurements.

Book excerpt: "In this magnificent book, Oliver Schuchard provides more than sixty-five exquisite black-and-white photographs spanning his thirty-eight years of photography. In addition, he explains the aesthetic rationale and techniques he used in order to produce these photographs, emphasizing the profound differences between, yet necessary interdependence of, craft and content. Although Schuchard believes that craft is important, he maintains that the idea behind the photograph and the emotional content of the image are equally vital and are, in fact, functions of one another. The author also shares components of his life experience that he believes helped shape his development as an artist and a teacher. He chose the splendid photographs included in this book from among nearly 5,000 negatives that had been exposed all over the world, from Missouri to Maine, California, Alaska, Colorado, France, Newfoundland, and Hawaii, among many other locations. Approximately 250 negatives survived the initial review, and each of those was printed before a final decision was made on which photographs were to be featured in the book. The final choices are representative of Schuchard's work and serve to substantiate his belief that craft, concept, and self must be fully understood and carefully melded for a good photograph to occur. This amazing work by award-winning photographer Oliver Schuchard will be treasured by professional and amateur photographers alike, as well as by anyone who simply enjoys superb photography."--Publishers website.

Available in PDF, EPUB and Kindle. Book excerpt: The Financial Crisis Inquiry Report, published by the U.S. Government and the Financial Crisis Inquiry Commission in early 2011, is the official government report on the United States financial collapse and the review of major financial institutions that bankrupted and failed, or would have without help from the government. The commission and the report were implemented after Congress passed an act in 2009 to review and prevent fraudulent activity. The report details, among other things, the periods before, during, and after the crisis, what led up to it, and analyses of subprime mortgage lending, credit expansion and banking policies, the collapse of companies like Fannie Mae and Freddie Mac, and the federal bailouts of Lehman and AIG. It also discusses the aftermath of the fallout and our current state. This report should be of interest to anyone concerned about the financial situation in the U.S. and around the world.THE FINANCIAL CRISIS INQUIRY COMMISSION is an independent, bi-partisan, government-appointed panel of 10 people that was created to "examine the causes, domestic and global, of the current financial and economic crisis in the United States." It was established as part of the Fraud Enforcement and Recovery Act of 2009. The commission consisted of private citizens with expertise in economics and finance, banking, housing, market regulation, and consumer protection. They examined and reported on "the collapse of major financial institutions that failed or would have failed if not for exceptional assistance from the government."News Dissector DANNY SCHECHTER is a journalist, blogger and filmmaker. He has been reporting on economic crises since the 1980's when he was with ABC News. His film In Debt We Trust warned of the economic meltdown in 2006. He has since written three books on the subject including Plunder: Investigating Our Economic Calamity (Cosimo Books, 2008), and The Crime Of Our Time: Why Wall Street Is Not Too Big to Jail (Disinfo Books, 2011), a companion to his latest film Plunder The Crime Of Our Time.
