  • Micro Pulse Lidar: Perfect Tool for Atmospheric Research

    Micro pulse style lidars are active remote sensing tools proven to be highly useful in atmospheric research. This style of backscatter lidar has been around for decades; however, incremental improvements in photon counting, sensitivity, polarization, optical filters, coatings, and precision machining of each element support increasingly accurate analysis. Each iteration of the ...

  • Multiple Instruments Work Together for a Better View of Air Quality

    Accurately identifying and quantifying particulate matter (PM) in the atmosphere is key to determining air quality. Researchers are particularly interested in PM that have a diameter of less than 2.5 micrometers because they are believed to contribute to heart and lung disease in humans and animals. These tiny particles are invisible to the naked eye and originate from power plants, fires, and ...

  • Statistical Description of Triaxial Shear Test Results

    Any probabilistic approach to slope stability assessment requires an adequate statistical description of soil strength. Current statistical methods of strength description are unsuitable for this purpose. A statistical technique of soil strength description appropriate for the probabilistic assessment of slope stability in c', f' soils under drained conditions is developed here. The technique is ...

  • Dallas eastside water treatment plant, Dallas, Texas - Case Study

    In 1996, consulting engineers under con-tract to the City of Dallas contacted Soil Stabilization Products Company Inc. (SSPCo) to discuss solutions for chronic problems caused by more than a dozen sliding failures per year on the outer slopes of a water treatment facility's lagoon. The facility, administered by Dallas Water Utilities, consisted of a series of water retention lagoons enclosed ...

  • Slope stability analysis of a borax stockpile site

    Stability investigations were conducted for a slope at the back of a borax stockpile site near the Bandirma Harbor in the northwestern Turkey. There was a slope failure at the site causing damage in the concrete sections of the harbour in front. Investigations started with deformation monitoring with an inclinometer. Failure mechanisms were determined with back analysis using method of slices and ...

  • Slope stabilization with Gleditshia caspica and Parrotia persica

    The stabilization roles of two species, Gleditshia caspica and Parrotia persica, were studied on slopes in northern part of Iran. Landslides developed in this area because of incorrect land use and clear cutting of forest to change to agriculture land. Spread planting of Gleditshia caspica and Parrotia persica can help to control instability of soil in this area. Bishop’s method was used to ...

  • Geoweb and geoblock solutions for trails and greenways - Case Study

    As communities develop and expand greenway and trails into environmentally-sensitive areas, finding cost-effective ways to protect the surface and adjacent land with low impact solutions is crucial. The challenge is to maximize permeability and/or green space while maintaining a trail environment that is stable, aesthetically-pleasing, relatively low maintenance, and environmentally-sound. The ...

  • Virginia dOT slope protection, Collinsville, Virginia - Case Study

    Prior to 1988, the sandy clay embankments along Route 220 near Collinsville, Virginia were subject to severe erosion and loss of vegetative cover, particularly after heavy rainfalls. The problems were most severe on embankments with steep slopes. These problems persisted despite numerous attempts to stabilize the soil and control surface erosion. In April of 1988, the Virginia Department of ...

  • Slope failures in municipal solid waste dumps and landfills: a review

    Between 1977 and 2005 six large-scale failures of municipal solid waste dumps and landfills have been recorded in the technical literature. The volumes of waste mobilized in the failures varied from 10—12 000 m3 in a failure that killed nearly 300 people to 1.5 million m3 in a failure that caused no deaths or injuries. Of the six failures, four occurred in dumps that, as far as is known, had not ...

  • Constant Volume Ring Shear Apparatus

    The paper describes a constant volume ring shear apparatus that allows the measurement of the undrained peak and residual shear strengths of cohesive soils. The undrained peak and residual strengths are applicable to seismic stability evaluations of slopes comprised of or founded on cohesive soil. The constant-volume ring shear apparatus is equipped with a mechanism to adjust the normal stress ...

  • Study on clutch engagement judder during launch process for dual clutch transmissions

    Clutch engagement judder, as part of vehicle noise, vibration and harshness (NVH), is an important vehicle attribute in the design of dual clutch transmissions (DCTs). This paper presents a system analytical model for clutch engagement judder during launch for DCT vehicles. Influencing factors on clutch judder, including internal factors (friction characteristic, damping, backlash) and external ...

  • Fairchild Avenue bridge project cae study

    In March 2012, significant storm-related flows through the Cuyahoga River threatened the construction of the new Fairchild Avenue Bridge Project in Kent, OH. ODOT engineers needed a quick solution to stabilize the eroding bank, while minimizing the need for costly and unsightly large diameter riprap. By incorporating ARMORMAX® into the design solution, ODOT was able to save significant funds ...

  • Erosion Protection of Steep Cut Slopes - Case Study

    In May of 1995, 70,000 sf of large-cell (GW40V) GEOWEB® slope protection system was utilized on Phase II of the Cyprus Miami Open-Pit Mine to stabilize the cut slopes upon completion of copper extraction at the site. Aggregate available on site was used to infill the GEOWEB 3D structure and provide erosion resistance and slope-surface stability on slopes with 70-ft. slope lengths, and as ...
