attention has ...
Investigation of Precise Relative Positioning through Varying Equipment Grades
(2022-02-22)
In this thesis, three methodologies are investigated in order to provide precise relative positioning knowledge between two dynamic platforms as equipment grade is varied. Two methods are integrated into the real-time ...
Investigation of Probe-Induced Dust Voids in a Weakly Magnetized Dusty Plasma
(2019-12-06)
Dust voids, or regions free of dust grains surrounded by dusty plasmas, have been observed in
a wide array of experimental configurations, from microgravity systems, to 3-dimensional dust
clouds, to 2-dimensional monolayers. ...
An Investigation of Psychological Factors Associated with Religious Involvement
(2007-08-15)
Research suggests that a relationship exists between church attendance and mental health, although the parameters of the relationship are unclear. The present study has focused on the relationship between religious involvement ...
Investigation of RF Noise in 28nm RF CMOS Using TCAD
(2015-05-07)
State of art of 28 nm RF MOSFET is studied using sentaurus process and device tools.
DC characteristics, such as C-V, Rs, Rd and I-V curves are calibrated by adjustment of
physics model. The relationship between saturation ...
Investigation of Ribosomal Dynamics in E.coli Using Single-molecule FRET
(2024-07-25)
Translation, the last step of gene expression, highly determines an organism’s normal function. Ribosomes are molecular motors that synthesize proteins from mRNA using amino acids carried by tRNAs. A ribosome’s mobility ...
Investigation of Seismic Design of Slab-on-Girder Bridge Details in Alabama
(2018-07-31)
The Alabama Department of Transportation (ALDOT) requested assistance to simplify and evaluate the process of designing typical slab-on-girder bridges for seismic loads. First, the determination of the seismic hazard in ...
An Investigation of Seventh Grade Students’ Attitudes Towards Animals in a Middle School Science Classroom in Rural Alabama
(2019-04-24)
This dissertation examines the different types of attitudes toward animals held by 7th grade students in one middle school in the rural southeastern part United States. This study was conducted using seven-point Likert ...
Investigation of Several Factors Affecting Total Alkalinity Concentration and Its Measurement
(2015-12-04)
The optimal endpoint pH for total alkalinity titrations decreased from 5.0 at 10 mg/L alkalinity to 4.2 for 300 mg/L alkalinity or more. The appropriate color changes for bromocresol green-methyl red (BG-MR) and methyl ...
Investigation of soy-based protein sources for largemouth bass (Micropterus nigricans) fingerlings on growth performance, health status, and disease susceptibility
(2025-04-22)
The aquaculture industry faces many concerns as we push to increase production to meet human food demands. This has contributed to an exponential rise in price and demand for marine protein and oil sources. Formulated feed ...
