A Soil Quality Index for Alabama
(2015-08-21)
Soil quality is how well soil performs the functions expected of it. Many of Alabama’s agricultural soils are considered poor quality due to compaction, excessive runoff, a history of severe erosion, low soil organic matter, ...
Soil- and Foliar-Applied Potassium in Upland Cotton (Gossypium hirsutum L.) Production
(2019-12-20)
Soil test recommendations for upland cotton (Gossypium hirsutum L.) fertility are often based on varieties which are no longer in production, meriting questions on whether increased potassium (K) is needed for new varieties ...
Soil-Planter Interaction Force Distribution as Affected by Planting Depth Setting and Planter Configuration
(2016-04-26)
Agricultural field planting operations encounter great spatial and temporal variability. Research has shown that seeding depth and soil loading, produced by planting equipment, affect early crop growth as well as crop ...
Soil-Structure Interaction and Imperfect Trench Installations As Applied To Deeply Buried Conduits
(2007-05-15)
The imperfect trench installation method is used to reduce earth pressure on deeply buried conduits. Few quantitative refinements to the imperfect trench installation method, however, have been added since the fundamental ...
Soil-Structure Interaction Effects on the Seismic Response of Steel Structures
(2021-07-15)
Significant earthquakes are one of the most damaging events for structures. Much research has been done to mitigate the effect of earthquakes on structures. Soil-structure interaction can have a significant impact on the ...
Solar Energy Conversion and PEM Technology for a Residential Back-up Power System
(2013-04-22)
Shown in this work are the characterization, simulation, and implementation of a small-scale back-up power system powered through solar energy conversion. The technical approach utilizes solar arrays with a proton exchange ...
Solder Joint Reliability & Prognostication of Lead Free Electronics in Harsh Thermo-Mechanical Environments
(2008-08-15)
The trends in the electronic packaging industry are to design smaller packages that have higher complexity, and to improve package reliability while reducing costs. These needs in the packaging industry have lead to a newer ...
Solder Joint Reliability Based Prognostic Health Management (PHM) Models for Life Prediction of Electronics Subjected to Harsh Thermo-mechanical Environments
(2013-12-04)
Field deployed electronics may accrue damage due to environmental exposure and usage after finite period of service but may not often have any macro-indicators of failure such as cracks or delamination. In real world setting ...
Solder Joint Reliability in Electronics Under Shock and Vibration Using Explicit Finite-Element Sub-Modeling
(2007-05-15)
Solder joint failure in electronic devices subject to shock and drop environment is one of the key concerns for the telecommunications industry. The recent trend towards miniaturization and increased functional density has ...
Solid Rocket Motor Internal Flow Solutions with FlightStream
(2021-07-13)
This thesis seeks to advance the state of the art for conceptual and preliminary design of
solid propellant rocket motors by adapting surface vorticity solution methods to the internal
ballistics problem. The practical ...
Solidification of Hydrocarbon Liquids using Polymer Blends
(2010-08-03)
Solidifiers are composed of dry, high molecular weight polymers that have a porous matrix and a large oleophilic surface area. They bond with the hydrocarbon liquids by molecular interaction (hydrogen bonding, London forces, ...
Solids Retention Governs Nitrification of Poultry Processing Wastewater using an Algal-bacterial Consortium
(2021-12-06)
As water demand increases worldwide, the utilization of alternative water sources, such as wastewater, is becoming necessary. The poultry processing industry generates nutrient-rich wastewater that could be treated and ...
Solubilization of nonstructural carbohydrates as a function of soaking interval and water temperature in southern forages commonly fed to equids
(2017-04-28)
Nonstructural carbohydrates (NSC) play a major role in the diet of equids prone to laminitis or afflicted with metabolic conditions such as insulin resistance. Although the threshold of <10% dietary NSC has been set as a ...
Solution Approaches to Large Scale Multistage Stochastic Programs with Endogenous and Exogenous Uncertainty
(2017-12-01)
The focus of this dissertation is the investigation of approaches to address the computational challenges of solving multistage stochastic programs (MSSPs) with both endogenous and exogenous uncertainty. My work to date ...
Solutions for Tractor-trailer Path Following at Low Speed
