Active and Passive Sensor Fusion for Terrestrial Hyperspectral Image Shadow Detection and Restoration
(2016-05)Acquisition of hyperspectral imagery (HSI) from cameras mounted on terrestrial platforms is a relatively recent development that enables spectral analysis of dominantly vertical structures such as geologic outcrops. Although ... -
Advanced SAR Interferometry Methods for Ground Displacement Estimation from Spaceborne and Airborne Platforms
(2016-05)Interferometric synthetic aperture radar (InSAR) is a powerful technique to monitor ground deformation phenomena, such as landslides, ground subsidence, seismological activities, and volcano dynamics. In this dissertation, ... -
Aggregation of Lead Phosphate Nanoparticles: Implications for Lead Immobilization in Soil and Pipes
(2017)Flint, Michigan (2014) and Washington D.C. (2001) found high levels of lead in their drinking water pipelines. Problem: Lead in pipes is corroding and contaminating the drinking water. Goal: To study the aggregation behavior ... -
An Automated and Remotely Operated Siphon System for Flood Control
(2018-05-10)The proposed siphon system aims to release water from a wetland before a heavy rainfall that is forecasted to produce flooding. The storage made available by the early release would provide water storage for the heavy ... -
AN EXPERIMENTAL STUDY ON REPAIR OF STEEL BRIDGE PILES USING GFRP CONCRETE-FILLED JACKET
(2014-12)Many bridges and structures in the United States that are supported on steel piles exhibit inadequate strength due to increasing load demand and aging due to corrosion The combination of increased load demand and reduction ... -
Application of Cupriavidus metallidurans and Ochrobactrum intermedium for Copper and Chromium Biosorption
(2013-05)Heavy metals at high concentrations are toxic to the environment and living organisms. The present study aims to investigate the best conditions for the removal of CuSO4.5H2O and KCrO4 by two bacterial species: Ochrobactrum ... -
Autogenic Processes on Supercritical Submarine Fans
(2015-05)Submarine fans are large landforms typically built on the continental slope and abyssal plain. They are a amalgamation of depositional lobes emplaced over time through avulsion cycles. These type of intermediate scale ... -
Bacteria and Virus Control by Electrochemical Coagulation and Microfiltration
(2014-05)Bench-scale experiments were performed to evaluate microorganism control by electrochemical coagulation and membrane microfiltration. Natural organic matter (NOM) present in natural waters appears to reduce the effectiveness ... -
Bed and suspended sediments as source and transport mechanisms for polychlorinated biphenyls in the Houston Ship Channel Estuary System
(2012-08)Polychlorinated biphenyls (PCBs) and polychlorinated dibenzo-p-dioxins/dibenzofurans (PCDD/Fs) are pollutants of global concern. Though their industrial histories differ, they both represent large classes of chemicals ... -
Behavior of FRP Strengthened Concrete Panel Elements Subjected to Pure Shear
(December 2)Several investigations have revealed that many aging civil engineering structures such as highway bridges are structurally deficient and need repairs and/or retrofitting. Among various solutions, fiber reinforce polymer ... -
BOND BEHAVIOR BETWEEN STEEL AND HIGH MODULUS CFRP PLATES AT MODERATLEY ELEVATED TEMPERATURES
(2014-12)This thesis presents the findings of a research study that was conducted to assess the effect of moderately elevated temperatures, up to 50oC, on the bond behavior of steel beams strengthened with externally bonded carbon ... -
CALIBRATION OF PHI FACTORS FOR PRESTRESSED BRIDGE GIRDERS
(2014-12)Calibration of the flexural resistance factors in the American Association of State Highway and Transportation Official’s (AASHTO) Load and Resistance Factor Design (LRFD) format is performed for bridge girders prestressed ... -
Carbon Dioxide Sequestration through Microbially-Induced Calcium Carbonate Precipitation Using Ureolytic Environmental Microorganisms
(2015-05)The development of affordable and eco-friendly strategies for carbon dioxide sequestration has become a matter of paramount importance to reduce or mitigate the effects of global climate changes. Today, the most used ... -
CARBON NANOFIBER AGGREGATE-BASED STUDY ON STRUCTURAL BEHAVIOR OF REINFORCED CONCRETE COLUMNS
(2014-12)Past studies have demonstrated that carbon nanofiber aggregate (CNFA) to be self-sensing and can be embedded in concrete structures to monitor the strain due to external loading. In this study, CNFAs were embedded in 16 ... -
Case and Parametric Study on the Collapse of the USS Salem Wharf
(2016-08-12)The research presented herein has two principal objectives, which are (i) to develop a numerical framework to predict the collapse load of highly redundant structures with stiff superstructures under vertical (gravity) ... -
