Seismic Analysis of Single and Grouped Helical Piles in Dense Sand with Soil-Structure Interaction
(2020)
The successful performance of helical piles under many loading conditions, specifically earthquake motions, make them very popular. Nevertheless, only a few, limited, realistic and quantitative studies on their seismic ...
IMPACT OF MOISTURE CHANGES IN UNSATURATED SOIL ENGINEERING APPLICATIONS
(2016-12-16)
The mechanical and hydraulic properties of soil above the groundwater table change due to unsaturated conditions. While common, considering soil to be saturated as a simplifying assumption in the design of many important ...
Expanding In-situ Surface Water Quality Monitoring Techniques for Optically Complex Inland Waters Utilizing small Unoccupied Aerial Systems (sUAS)
(2021-05-14)
Remote sensing is described as the art and science of interpreting information (e.g., reflectance) collected from a target object (e.g., vegetation) using technology (e.g., satellites, occupied aircraft, and small unoccupied ...
Application of Rapid-Setting Belitic Calcium Sulfoaluminate Cements in Pretensioned, Prestressed Concrete
(2023-05-13)
In recent years, urgency for adopting sustainable materials has come to the forefront of the cement and concrete industries. Belitic calcium sulfoaluminate (BCSA) cement is an alternative cement which has a production ...
Utilization of coal combustion by-products for in situ treatment of acidic mine waters.
(1999)
The goal of this research was to determine how to effectively treat AMD in situ using CCBs and to develop a better understanding of the chemical and physical processes involved with the treatment. AMD treatment within the ...
Redox functional groups of humic substances.
(2004)
A new analytical technique based on palladium (Pd) and H2 catalytic system showed significant potential as a useful method for reliably assessing redox sites in humic substances. The technique identifies redox sites as a ...
Shear Performance of Non-Traditional Concrete
(2018-08-02)
Concrete is the second most consumed material in the world, second only to water. Concrete has been around in different forms for centuries, and science and technology continually push the previously believed limits. Two ...
CHARACTERIZING UNCERTAINTY OF A HYDROLOGIC MODELING SYSTEM FOR OPERATIONAL FLOOD FORECASTING OVER THE CONTERMINOUS UNITED STATES
(2015)
The purpose of this work was to study the macro scale patterns of simulated streamflow errors in order to characterize uncertainty in a hydrologic modeling system and establish the basis for a probabilistic forecasting ...
Methodology for the selection of appropriate technology of water distribution systems in less developed countries /
(1984)
The output can be used by promoters, designers, planners, and the community to determine in advance the needs for manpower and the water rates that are necessary to be met in order to maintain the water distribution system ...
