Algorithm For Geodetic Positioning Based On Angle-Of-Arrival Of Automatic Dependent Surveillance-Broadcasts, Richard Allen Gross

Masters Theses

This paper develops a non-precision, three-dimensional, geodetic positioning algorithm for airborne vehicles. The algorithm leverages the proliferation of Automatic Dependent Surveillance – Broadcast (ADS-B) equipped aircraft, utilizing them as airborne navigation aids to generate an RF Angle-of-Arrival (AOA) and Angle-of-Elevation (AOE) based geodetic position. The resulting geodetic position can serve as a redundant navigation system for use during locally limited Global Navigation Satellite System (GNSS) availability, be used to validate on-board satellite navigation systems in an effort to detect local spoofing attempts, and be used to validate ADS-B position reports.

The navigation algorithm is an implementation of an Extended Kalman …

Study Of Cooling-Drag In A Generic Passenger Car Using Cfd And Wind Tunnel, Md Maruf Hossain

Masters Theses

The focus of the study is to explore aerodynamic aspects of cooling airflow. As a result of this study, an efficient multi-domain aero-thermal model was developed to analyze the cooling drag of a generic passenger vehicle. Cooling drag is described as the additional force that the production vehicle has to overcome while moving in comparison to the force if all the openings were closed. Though this model was developed based on the sedan class vehicle, the applied methodology could be generalized for other ground vehicle types. As a part of the presented model, a unique simplified geometric model is developed …

Dental Topographic Analysis Of Maxillary And Mandibular Phyllostomid Bat Dentitions: Implications For Dietary Prediction In The Fossil Record, Colin Pellegrom

Masters Theses

Mammalian dental anatomy has evolved in accordance with the physical properties of its diet, and multiple features on each tooth have specific functions related to the breakdown of food during mastication and ingestion. Tooth structure is under tight genetic control and much of the anatomical variation in dentition across species is related to adaptation to a specific dietary regime. This diet-dentition relationship can be exploited to reconstruct mammalian diets from fossil specimens through calculation of dental topographic metrics. To date, most studies of dietary reconstruction using dental topography have focused on mandibular molars; thus, this study seeks to test whether …

The Sandman: The Artifice Of Comics And Power Of Dreams, Nathan Teft

Masters Theses

Neil Gaiman’s Vertigo Series The Sandman is an exceptional artistic endeavor. From “Preludes and Nocturnes”(1988) to “The Wake” (1996), Gaiman worked alongside a team of talented artists and graphic designers to produce an indelible work of revisionist mythology. This thesis will attempt to establish the framework by which our modern literary canon has celebrated classical Western myths while relegating graphic or visual forms of literature or outright neglecting comic myths altogether. Scott McCloud’s Understanding Comics will frame the discourse for pictographic analysis of Neil Gaiman’s mythological revisionism of Milton’s Paradise Lost in Season of Mists, Italo Calvino’s Invisible Cities …

The Correlation Between Sleep And Lifespan In Drosophila Melanogaster, Joshua Randall Lisse

Masters Theses

”Adequate sleep is associated with an individual’s health. Too little sleep is associated with many health problems, including cardiovascular disease, obesity, and a general increase in all-cause mortality. Yet the molecular changes that link poor sleep and changes in health are still not well understood. Individuals have a unique daily need for sleep, and deviations from the animal’s regular sleeping patterns can be indicative of, or result in, underlying changes in its health. Therefore, we hypothesize that changes in the sleep architecture in Drosophila melanogaster reflect changes in the fly’s health.

We determined sleep architecture in wild-type male flies over …

Microwave Detection Of Surface Breaking Cracks In Metallic Structures Under Heavy Corrosion And Paint, John Robert Gallion

Masters Theses

"We live in the world of "aging infrastructures". In this environment, critical and heavily utilized infrastructure, i.e. ships, planes, bridges, etc., are operating at or beyond their designed age. Replacement is no longer an option and "retirement for cause" is the current approach to maintenance and replacement. Consequently, there is an ever-increasing demand for efficient and robust nondestructive evaluation (NDE) methods that can determine the physical health of these structures. Large structures, which are primarily made of metals, either steel or aluminum, are susceptible to high-stress cracking and corrosion. Stress-induced cracks in heavily corroded steel, used in bridges, railroads, storage …

Functional Characterization Of Glutamate Carboxypeptidase Ii In Caenorhabditis Elegans, Hashni Epa Vidana Gamage

Masters Theses

Glutamate carboxypeptidase II (GCPII) is a transmembrane zinc metalloprotease expressed in a number of organisms: from yeast to worm to humans. In humans, GCPII has been observed as a multifunctional protein and expressed in prostate, intestine, kidney, brain, tumor-associated neovasculature and other tissues as five paralogs. In the human small intestine, hGCPII is proposed to facilitate the folate absorption by cleaving terminal glutamate residues in dietary folates. Folates act as a cofactor in one-carbon metabolic pathways such as nucleotide synthesis, amino acid synthesis, DNA repair, and consequently involved in cell division and growth. The hGCPII homolog is found in the …

The Development And Implications Of Social Studies And History Curricula In Ghana, Razak Kwame Dwomoh

Hidden Symmetries In Classical Mechanics And Related Number Theory Dynamical System, Mohsin Md Abdul Karim

Masters Theses

Classical Mechanics consists of three parts: Newtonian, Lagrangian and Hamiltonian Mechanics, where each part is a special extension of the previous part. Each part has explicit symmetries (the explicit Laws of Motion), which, in turn, generate implicit or hidden symmetries (like the Law of Conservation of Energy, etc). In this Master's Thesis, different types of hidden symmetries are considered; they are reflected in the Noether Theorem and the Poincare Recurrence Theorem applied to Lagrangian and Hamiltonian Systems respectively.

The Poincare Recurrence Theorem is also applicable to some number theory problems, which can be considered as dynamical systems. In …

Vote Choice Of Minority Groups: Emphasizing Their Issue Preferences, Md Kamrul Islam

Masters Theses

In explaining vote choice of minority groups, scholars of American politics often characterize them as natural democrats. They argue that they have become natural Democrats because of their minority identity and the constraints they faced throughout the history of the United States. However, this thesis questions the characterization and highlights the issue preferences of minority groups; it analyzes whether their issue preferences have an impact on shaping their vote choice. By analyzing the Cooperative Congressional Election Study (CCES) 2016 survey, this thesis has explored that minority groups vote for candidates who pay greater emphasis on the issues they care about. …

Middle And High School Teachers' Praise And Reprimand Delivery, Emma Riedesel

Masters Theses

The benefits of increasing teacher praise and decreasing teacher reprimand (for both students and teachers) is well-established in the literature. The purpose of this study was to expand the literature on teachers' natural use of praise and reprimand, specifically in terms of how teachers deliver praise and reprimand. Sixty-six middle (sixth through eighth grade) and high school (ninth through twelfth grade) teachers' delivery of praise and reprimand to individual (one student), small clusters (two to six students), and large groups (seven or more students) during a 20-minute observation were examined. Teachers delivered significantly more general praise to individual students, rather …

The Impact Of School Nutrition Education And Physical Education Programs On Weight Status Of Obese Children Aged 5-12 Years, Lamia Alotaibi

Masters Theses

Epidemiological studies indicate that 12.5 million children and adolescents are considered obese (Center for Disease Control and Prevention, 2017). Obesity is on the rise globally, and while it affects both children and adults, early measures can be taken to reduce the number of children who are obese, and therefore, come into adulthood at a higher risk for obesity-related diseases, such as hypertension, cardiovascular disease, and sleep apnea. There are many studies in which programs are implemented and tested for effectiveness; therefore, a systematic review of these studies that examine which factors play into overall obesity prevention and health improvements among …

Juxtaposing Primary- And Intermediate-Elementary Trade Books’ Historical Representation Of Amelia Earhart, Rachael A. Burkhardt

Masters Theses

Amelia Earhart can be used in the classroom not only to interest students but can also be used to cover Common Core State Standards (CCSS), National Council for the Social Studies (NCSS) framework, and Next Generation Science Standards (NGSS). When teaching Amelia Earhart, textbooks, trade books, and primary sources can be used, however one must be careful with the misrepresentations each resource can portray. To look at what is misrepresented, omitted, and included within primary and intermediate grade level trade books, 32 books were scrutinized. The trade books being analyzed were found to have some historically representative and misrepresentative elements …

Impact Of First-Generation Student Status On Graduate School Experience, Rachelle Ann Krausen

Masters Theses

Just because first-generation students are in graduate school and have accomplished a bachelor’s degree docs not mean they overcame the status risks and are prepared for the graduate school experience. This at-risk population is left relying on the same tactics utilized during undergrad to endure graduate school. The present qualitative study describes how first-generation graduate students (FGGS) experience a master’s degree program with new challenges mentally, socially, and academically. To gain insight, semi-structured interviews of four participants were conducted to answer the following questions: 1) what motivated FGGS to pursue a master’s degree: 2) What resources are FGGS aware of …

Exploratory Factor Analysis Of The Canadian Wechsler Intelligence Scale For Children-Fifth Edition For A Sample Of First Nations Students, Jessica Hanson

Masters Theses

Native Americans and First Nation students are overrepresented in special education and underrepresented in structural bias research of the intelligence measures that place them there. There are several empirical studies of test bias on the Wechsler scales due to their popularity within the school system, however there is little exploratory factor analysis research on these scales with the Native American Indian population. Further, the Native American Indian and First Nation population is a relatively small minority group compared to other racial and ethnic groups in North America and this group is underrepresented in government statistics and overlooked in funding for …
