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 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 ...

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 ...
An Investigation of Species Relationships within Marshallia Schreb. [Asteraceae] and Mitochondrial Genomes within Poaceae
(2018-04-24)
Genomic sequencing has become ubiquitous within the discipline of Biology. Here I use
two case studies in which whole genomic DNA facilitates answers to foundational biological
questions for organisms that do not have ...
An Investigation of Student Conjectures in Static and Dynamic Geometry Environments
(2005-05-15)
This study was designed to investigate the mathematical conjectures formed by high school geometry students when given identical geometric figures in two different types of geometric environments. Student conjectures ...
An Investigation of Teachers’ Knowledge and Use of Positive Behavior Supports and Applied Behavior Analysis Strategies in Saudi Arabia
(2021-11-29)
Behavior management can be a challenge for elementary and secondary classroom teachers in Saudi Arabia. Some elementary and secondary teachers in Saudi Arabia report a lack of preparedness in implementing effective behavior ...
An Investigation of the Academic, Personal, Professional Experiences and Multicultural Competence of Diversity Staff in Higher Education
(2012-07-31)
There is a gap in the research about the preparation of diversity staff and their multicultural competency. In this dissertation, I address this void by examining the academic, personal, and professional experiences and ...
Investigation of the Characteristics of an Axisymmetric Jet Subjected to Azimuthal Forcing
(2013-05-15)
