  • Locating pipes and cables case study

    GPR can be used to determine the location and depth of metallic, non-metallic, plastic, concrete and asbestos-concrete utilities, and cables (power, signal, etc.) Locating of  City Utilities The VIY3-300 GPR was used for locating of city utilities (water, gas, sewer, etc.). This profile shows city utilities at a depth of 1.2 and 2.0 meters (wave speed is 130 meters per ...

  • MASW and resistivity sounding case study

    Anclote Natural Gas Conversion Project, Pasco County, FL  Our client was coordinating the conversion of an oil-burning power plant to natural gas. As part of the associated geotechnical study, GeoView, Inc. was tasked with determining the S-wave velocity and vertical resistivity structure at the site. For the seismic portion of the study, MASW (Multi-channel Analysis of Surface ...

  • A new packing structure with innovative advantages

    Abstract The Raschig Super-Pak is a new geometric packing design which through an innovative structure, has three major advantages over other high-performance packing: lower pressure drop, higher capacities, and better separation efficiency. The performance data measured at the Separations Research Program (SRP) at the University of Texas at Austin are presented and evaluated in ...

  • Contrasting suspended covers reveal the impact of an artificial monolayer on heat transfer processes at the interfacial boundary layer

    The highly variable performance of artificial monolayers in reducing evaporation from water storages has been attributed to wind speed and wave turbulence. Other factors operating at the interfacial boundary layer have seldom been considered. In this paper, two physical shade covers differing in porosity and reflectivity were suspended over 10 m diameter water tanks to attenuate wind and wave ...

  • Simultaneous initiation of cut and production holes in trench method of blasting

    The modified drilling and blasting pattern included two rows of cut holes drilled at intermittent locations in a blasting round, i.e., two rows of cut holes were drilled after every 10–12 rows of production holes. The burden and spacing for cut holes were 0.4 and 0.5 m, respectively, and for production rows the blast geometry was 0.7–0.8 m burden and 0.9 m spacing. In the same round, rows of cut ...

  • Turbulent Mixing in fine-scale phytoplankton layers: Observations and inferences of layer dynamics

    Turbulence measurements in fine-scale phytoplankton layers in the Gulf of Aqaba (Red Sea) were used to evaluate mechanisms of layer formation, maintenance, and breakdown. Simultaneous profiles of chlorophyll a (Chl a) fluorescence and temperature microstructure were measured in the upper 40 m of a 430 m water column over a 16-d period, using a Self Contained Autonomous MicroProfiler (SCAMP). ...

  • Geotech and construction case study

    Pre-Construction Surveys The VIY2-300 GPR was used to survey Korolenko Square and contiguous area in Rivne town from 5 to 6 December 2006. Surveys were carried out both on the lawns and reinforced paving slabs. Large building structures, presumably ruined bridge foundation, are marked in blue. River at this place is no more than 100 years. Large buried ...

  • miniSODAR

    The miniSODAR is a high-frequency Doppler sodar system that was designed to measure the atmospheric wind profile from 15 meters to 150/200 meters (data is often available to 250 meters) in 5-meter increments. It operates by generating a short tone burst (30 ms to 100 ms) in the frequency range of 4 kHz to 6 kHz. It monitors the low-level acoustic signal echoed by the atmosphere. The echo is ...

  • U.S. - China renewable energy partnership

    In the fall of 2010, a team of engineers carefully installed an unusual, six-foot high enclosure on a windy plain some 200 miles northwest of Beijing. Inside the gray casing – which looks a bit like a giant rabbit from some angles – is a sensitive device that uses sound waves to measure wind speeds hundreds of feet up into the sky. It’s called the Triton Sonic Wind Profiler, and ...

  • Impact of Tsunami Disaster on the Water Environment

    ABSTRACTThe earthquake that generated the great Indian Ocean tsunami of 2004 is estimated to have released the energy of 23,000 Hiroshima-type atomic bombs, according to the U.S. Geological Survey (USGS). The earthquake occurred on December 26, 2004 was an undersea earthquake originated in the Indian Ocean off the western coast Indonesia and generated tsunamis that were among the worst disasters ...

  • Cavitation Reactors

    By combining the developments in acoustics, hydrodynamics and chemical kinetics, a new promising device is entering the market: the cavitation reactors, used for processing of suspensions, emulsions and for intensification of chemical processes in solutions. These devices are can be used either separately (in laboratory test-benches) or in industrial mixing processes. In today’s market, two ...
