Stream Function Path Planning and Control for Unmanned Ground Vehicles
(2008-08-15)
This research develops a harmonic potential field based path planner and controller. The first component of the dissertation compares several analytical and numerical potential field generation methods. To overcome ...
Stream-breeding amphibian responses to land use distrubances
(2009-04-29)
Conversion of land from an undeveloped state into agricultural or urban areas is widespread. Urban areas in particular are growing both in size and number globally. Such land use changes can potentially have negative ...
Streamflow Signature Analysis of Long-Term Effects of Urbanization on Hydrologic Alteration in the Southeastern United States
(2018-12-19)
Urbanization in the southeastern United States has risen exponentially over the past few decades. This increase causes runoff to have a greater surface flow, a smaller interflow, and sometimes a reduced baseflow by changing ...
Strength Assessment of Soil Cement
(2013-01-07)
Soil cement is a mixture of soil, portland cement and water that, once compacted and cured, forms a strong and durable pavement base. Construction practices and variance among core strength data have led to questions ...
Strength Assessment of Soil Cement
(2016-12-07)
Soil cement is a mixture of soil, portland cement, and water that is compacted and cured to form a pavement base. Due to construction practices and variances in core strengths, questions have arisen concerning quality ...
Strength Assessment of Soil Cement Base in Alabama
(2020-07-30)
Soil cement is a mixture of soil, portland cement, and water that is compacted and cured to form a strong, durable pavement base. Variances among construction practices and core strength data have led to questions concerning ...
The Strength of Attractiveness and the Power of Visual Nonverbal Communication When Rating One's Communicative Competence
(2006-05-15)
The effect that actual communicative competence, attractiveness, and method of observation have on one’s perceived competence was examined. Four hundred and thirty-three participants either watched video or listened to an ...
Stress Analysis in Bipolar Transistors
(2016-05-03)
Stress effects in semiconductor devices have gained significant attention in semiconductor industry nowadays. Stress effect in semiconductor devices is used as a beneficial effect in sensor applications and strain engineering ...
Stress in Alabama’s Education Employees: Intensity, Manifestation, Connection to Turnover Intentions, and Alleviation Techniques
(2023-04-27)
Schools across America are filled with educators who are skilled in their craft but stressed with their work, which is leading to alarming rates of burnout, turnover, and attrition. Much of the existing professional ...
Stress Mapping of Textile Composite Materials and Its Application in Interfacial Shear Behavior
(2005-12-15)
Mapping of the stress distribution in composite materials, both at the fiber/matrix interface and at the composite constituents themselves, is important to understand the material mechanical response. Stress mapping can ...
