A Hybrid Retrodirective Array Based on Delay-Locked Loop Hybrid Phase Conjugators
(2020-06-15)
This dissertation discusses the design, construction, and characterization of a new Hybrid Retrodirective Array (HRA) as a possible beamforming technology for 5G wireless communication networks. A Delay-Locked Loop based ...
Hybrid Sampling for Uncertainty Quantification in Systems with High Dimensional Parameter Spaces
(2022-05-01)
Spatial models formulated as partial differential equations, often include space dependent parameters that are not readily estimable and are therefore uncertain.
There are two broad classes of methods for computing ...
Hydraulic Management of SDI Wastewater Dispersal in an Alabama Black Belt Soil
(2009-12-11)
Approximately 52% of the 14000 km2 Alabama Black Belt region is unsuitable for conventional onsite wastewater treatment systems because of low hydraulic permeability, high water table, or other restrictive soil properties. ...
Hydraulic Solenoid Valve Reliability and Modeling Study
(2008-12-15)
The current work has studied the reliability of a solenoid valve (SV) used in automobile transmissions through a joint theoretical and experimental approach. Based on an extensive literature search, the most common failures ...
Hydro-peaking Impacts on Growth, Movement, Habitat Use and the Stress Response on Alabama Bass and Redeye Bass, in a Regulated Portion of the Tallapoosa River, Alabama
(2012-07-02)
Altered flow regimes caused by dam construction and operation can affect aquatic organisms in a variety of ways. The Tallapoosa River, in east-central Alabama, has been extensively impounded for flood control, navigation ...
Hydroclimate variability and predictability in the Southeastern United States
(2023-12-05)
The hydroclimate is the study of the hydrological cycle in the climate context, it is defined as the intersection of climatology and hydrology, especially energy and moisture exchanges between and within the two systems. ...
Hydrodynamic and Water Quality Modeling of Lake and Estuary Systems Considering Inflow and Outflow Effects
(2023-12-06)
Algal bloom, fish kill, hypoxia, and toxicity are some of the water quality issues faced by many waterbodies, from lakes to estuaries. Internal or external nutrients cause excess growth of algae and then lead to low or no ...
Hydrodynamic and Water Quality Simulations in the Perdido and Wolf Bay System
(2019-05-05)
The widespread fish kills of Gulf menhaden (Brevoortia patronus) were reported beginning on 7/31/2015 in the Cotton Bayou, Orange Beach City, Alabama. Although some possible reasons for the fish kill event were provided ...
Hydrodynamics Modeling to Study the Impacts of Hurricanes without and with NNBFs in the Coastal Region of Mobile Bay
(2023-12-07)
The coastal communities of Mobile Bay, AL, are facing a serious problem of flooding due to storm surges. With the increasing economic and social activities along with the increasing frequency as well as the intensity of ...
Hydrogel Nanoparticles from Supercritical Technology for Pharmaceutical and Seismological Applications
(2011-01-24)
This research focuses on hydrogel nanoparticle formation using miniemulsion polymerization and supercritical carbon dioxide. Hydrogel nanopowder is produced by a novel combination of inverse miniemulsion polymerization ...
Hydrogen Production by Supercritical Water Reforming of Bio-Oil Components
(2012-11-06)
The concept of a hydrogen economy is gaining traction with an ever increasing body of work focusing on all aspects of the overall process which consists of converting a fuel source to hydrogen followed by storage and ...
Hydrogen Production from Renewable Bio-Based Sources
(2014-05-02)
Efficient means of power generation is the key to coping with increasing energy demands due to population expansion. Non-renewable sources like fossil fuels, coal, and methane contribute to the carbon footprint, resulting ...
Hydrogen Production in Supercritical Water
(2011-04-15)
Hydrogen has been considered as an environmentally friendly energy carrier for the future. It is not found freely in nature but must be obtained by processing hydrogen containing compounds. Current industrial-scale ...
Hydrogen Production Via Thermocatalytic Decomposition of Methane Using Carbon Supported Materials
(2018-01-09)
Convectional hydrogen (H2) production process such as steam methane reforming process (SMR) produces massive amounts of CO2 (i.e., 13.7 kg CO2 per kg H2 production). Because of the large amount of CO2 production during the ...
