General Response Of Kneading-compacted Unsaturated Silty Sand Under Drained And Undrained True Triaxial Testing
(Civil & Environmental Engineering, 2007-08-23)A comprehensive series of 36 drained and 36 undrained true triaxial tests was accomplished to investigate the stress-strain-strength behaviour of kneading-compacted unsaturated silty sand (SP-SM) under multi-axial stress ... -
Geohazard Potential Of Rainfall Induced Slope Failure On Expansive Clay
(Civil & Environmental Engineering, 2013-03-20)Each year, rain induced slope failures cause significant damages in highway infrastructures and environments, as well as tragic losses of human lives around the world. Rainfall-induced slope failure is a common problem in ... -
Group Assignment and Annual Average Daily Traffic Estimation of Short-term Traffic Counts Using Gaussian Mixture Modeling and Neural Network Models
(2016-09-13)The grouping of similar traffic patterns and cluster assignment process represent the most critical steps in AADT estimation from short-term traffic counts. Incorrect grouping and assignment often become a significant ... -
Group Resistance Of Recycled Plastic Pin In Sustainable Slope Stabilization
(Civil & Environmental Engineering, 2014-07-14)Slope failure is a common phenomenon in areas with slope constructed on high plasticity clay and shallow slope failure is predominant in North Texas. The cumulative maintenance cost of minor slides is equal or greater than ... -
HARMFUL ALGAL BLOOMS AND BIOLOGICAL TOXINS PRODUCTIONS; FROM INTEGRATED MONITORING APPROACH TO ON-SITE SOLAR PHOTOCATALYTIC DECOMPOSITION
(2016-12-20)Occurrence of Harmful Algal Blooms (HABs) worldwide has caused concern to environmental and health authorities because of their potential to generate and release biological toxins. In particular, microcystins (MCs) produced ... -
Heat and water transport in soils and across the soil-atmosphere interface: 1. Theory and different model concepts
(Wiley; American Geophysical Union, 2017-02-03)**Please note that the full text is embargoed** ABSTRACT: Evaporation is an important component of the soil water balance. It is composed of water flow and transport processes in a porous medium that are coupled with heat ... -
Heat and water transport in soils and across the soil-atmosphere interface: 2. Numerical analysis
(Wiley; American Geophysical Union, 2017-02-03)**Please note that the full text is embargoed** ABSTRACT: In an accompanying paper, we presented an overview of a wide variety of modeling concepts, varying in complexity, used to describe evaporation from soil. Using ... -
Heat Transfer in Unsaturated Soil with Application to Borehole Thermal Energy Storage
(Soil Science Society of America; Geological Society of America; Wiley Open Access, 2016-09-29)**Please note that the full text is embargoed** ABSTRACT: In this study, we numerically and experimentally evaluated heat transfer in soils under unsaturated conditions in the context of simulating a laboratory-scale, ... -
HPFRC and RC Slab-Beam-Column Connections under Extreme Earthquake Loading and Further Improvement of Novel Double-Beam-Coupling Beams
(2018-12-10)The work presented in this dissertation is divided into two parts. Each part has drawn its own results. Reinforced concrete (RC) buildings resist a strong earthquake through structural foundations, diaphragms, and ... -
Hydraulic Performance Evaluation Of Different Recirculation Systems For ELR / bioreactor Landfills
(Civil & Environmental Engineering, 2013-07-22)The major aspect of bioreactor landfill is the addition of liquid and recirculation of collected leachate back into the waste mass through the subsurface Leachate Recirculation System (LRS). The leachate recirculation ... -
Hydraulic Performance Evaluation of Evapotranspiration Cover Systems
(2016-12-07)Although alternative covers such as the evapotranspiration (ET) landfill cover system promise to provide equivalent or greater performance than conventional cover systems, uncertainties remain on the performance of these ... -
HYDROCARBON POOL FIRE PERFORMANCE OF FIBER REINFORCED POLYMER (FRP) STRENGTHENED AND THERMALLY INSULATED BRIDGE GIRDERS
(2016-12-15)Highway bridges encounter various extreme load hazards, such as earthquake, flood, blast, collision, wind and fire during their design lives. The effect of accidental, natural or man-made fire on bridges is one of the least ... -
