Design Of An Ultra-Wideband Spiral Antenna For Ground-Penetrating Microwave Impulse Radar Applications, Bradley Curtis Hutchinson

Master's Theses

Radar systems that allow early detection of underground IEDs can save lives. The Microwave Impulse Radar (MIR) capable of IED detection requires antennas capable of transmitting sub-nanosecond pulses over ultra-wideband (UWB) frequency ranges. This thesis investigates the suitability of a novel MIR antenna for high-accuracy ground-penetrating radar (GPR) applications. Key GPR antenna considerations are pulse dispersion, size, and cost. UWB horn antennas provide excellent dispersion performance but limit system efficacy due to significant size and cost requirements. Micro-strip spiral antennas provide a low-cost alternative to UWB horn antennas, but common spiral designs demonstrate poor pulse dispersion performance. The article “Low-Dispersion …

Gods And Gurus In The City Of Angels: Aimee Semple Mcpherson, Swami Paramananda, And Los Angeles In The 1920s, Amy Hart

Master's Theses

This project focuses on two case studies as representative examples of Los Angeles’ progressive tolerance in the period of the 1920s: The Pentecostal mega-church of Aimee Semple-McPherson, and the Vedanta Ashram of Swami Paramananda. Both religious institutions opened in Los Angeles in 1923, just thirteen miles away from each other, and continued to thrive side-by-side throughout the twentieth century until present day. Each religious figure spoke to a part of the growing Los Angeles population: McPherson’s staunchly Christian, emotionally-driven, Hollywood-style ministry appealed to a large number of Los Angeles natives and newly-arrived immigrants, rocketing the emerging Pentecostal denomination into nationwide …

Master's Theses

The multibillion dollar agricultural industry is an important part of the United States economy, and the management of factors that affect crop and human health is imperative to maintaining this economic sector. The fungi Botrytis cinerea, Fusarium pallidoroseum, and Fusarium moniliforme are the causative agents of several plant diseases and can cause significant crop loss both before and after harvest in commodities such as strawberries, lettuce, citrus, and grains. Fungicides are employed to control these phytopathogens, but the use of these chemicals has led to an increase in fungicide resistance and may negatively affect the environment and human …

Gpuhelib And Distributedhelib: Distributed Computing Variants Of Helib, A Homomorphic Encryption Library, Ethan Andrew Frame

Master's Theses

Homomorphic Encryption, an encryption scheme only developed in the last five years, allows for arbitrary operations to be performed on encrypted data. Using this scheme, a user can encrypt data, and send it to an online service. The online service can then perform an operation on the data and generate an encrypted result. This encrypted result is then sent back to the user, who decrypts it. This decryption produces the same data as if the operation performed by the online service had been performed on the unencrypted data. This is revolutionary because it allows for users to rely on online …

Reviving Mesopotamia: Genocide And The Preservation Of Cultural Heritage In The Nationalist Music Of William Daniel (1903-1988), Rashel Pakbaz

Master's Theses

Once an illiterate Christian community suppressed by its Muslim neighbors, the Mesopotamian population in Persia benefitted from the American missionaries establishing schools and hospitals that helped their culture and language flourish in the late 1800s. Their survival as a people and a culture was threatened, however, when the Muslim Ottoman Empire began the Christian Genocide in Eastern Anatolia during World War I. As a survivor of these horrific events, composer William Daniel (1903-1988) felt the need to preserve and promote Mesopotamian culture through music, and as a Western trained musician, he successfully developed a nationalist style of music based on …

Asylia And Peer Polity Interaction In The Hellenistic Period, Kathleen Ann Kirsch

Master's Theses

This thesis proposes that the Peer Polity Interaction Theory can explain the spread of the civic title of territorial asylia (inviolability) in the Hellenistic period. The Greeks had always considered sacred space to be inviolable; thus there was no apparent need to acquire a separate title of inviolability. During the Hellenistic period, however, ambassadors canvassed the Greek world for recognition of asylia, and acceptances were inscribed in stone and placed in highly visible places. It was clearly a particularly sought after title.

By surveying the primary epigraphic and numismatic sources and examining asylia in the context of the Peer Polity …

Investigation Of Population Structure And Distribution Of The Invasive Bryozoan Watersipora Species Along The California Coast Using Nuclear And Mitochondrial Dna, Darren James Wostenberg

Master's Theses

This study combined microsatellite nuclear DNA analysis with cytochrome c oxidase 1 (COI) mitochondrial DNA analysis to evaluate coastal population structure, environmental factors influencing population distribution, and the potential for hybridization among coexisting Watersipora haplogroups along the California coast. Mitochondrial DNA analysis of the COI gene identified three haplogroups: W. subtorquata clade A, W. subtorquata clade B, and W. new species. Analyses resulted in seven haplotypes for haplogroup clade A, and a single haplotype in each haplogroup clade B and new species. Microsatellite data indicated the greatest source of genetic variation in the two species examined (W. subtorquata and W. …

Master's Theses

This study exploits a quasi-random assignment of clients to loan officers using a unique database and survey from a large microfinance bank in Nigeria to show that opposite-sex preferences affect credit demand and supply. We find that clients matched to loan officers of the opposite gender are more likely to receive credit and are more likely to return for an additional loan with the credit lender.

The Impact Of Foreign Direct Investment On Labor Market Measures: Evidence From Sub-Saharan Africa, David A. Mayom

Master's Theses

There is scant literature examining the relationship between foreign direct investment (FDI) and labor market measures in Sub-Saharan African (SSA) countries. This paper explores the effect of FDI on the labor market measures using panel data of 48 Sub-Saharan African Countries from 1991 to 2009. The result indicates that FDI has a positive and significant effect on employment implying that an increase in the inflow of FDI is associated with higher employment. Thus, Sub-Saharan African governments should strongly consider poverty alleviation and employment policies that encourage and direct FDI to the industries where it can significantly reduce unemployment.

Crowded Out: The Effect Of Sex Ratios On The Sex Worker Labor Market And Migration In India, Michael Dickerson

Master's Theses

India’s skewed sex ratios have lead to the destruction of marriage markets in many villages as well as an increase in violence against women. This paper examines how India’s distorted sex ratios effects the migration of sex workers. By using a modified gravity model of migration the results in this paper indicates that an over supply of sex workers in a local market leads to a crowding out effect, and pushes the women to migrate to districts with more men than women. This paper contributes to the literature by bringing more clarity to how the labor market impacts the decisions …

The Relevance Of Economic, Institutional And Cultural Determinants For Venture Capital Investments. A Us-Europe Comparison., Nadja Benes

Master's Theses

This study analyzes the determinants of early-stage VC investments by identifying characteristics in the economic, institutional, as well as cultural framework that could explain the diverging levels of early-stage VC investments across countries. Data was assembled for 16 countries during the period from 1995 until 2013. The results indicate that countries that are more open to trade are associated with higher levels in early-stage venture capital. A higher unemployment rate negatively affects a country’s level of early-stage VC funds. Higher R&D expenditures as a proxy for the technological and innovation capacity in a country as well as a higher value …

Unintended Consequences Of Enforcement In A Fisheries Institution: Results From An Artefactual Experiment In Tanzania, Spencer Maccoll

Master's Theses

Overfishing and the destruction of fishing commons in developing countries is a growing problem. Policymakers and local community leaders are looking for solutions to keep their fishing commons sustainable. Fines and enforcement mechanisms are commonly suggested to help preserve the commons. This paper discusses a novel artefactual experiment conducted throughout several fishing communities in Tanzania to determine the effect of enforcing a ban on illegal fishing gear on fishing behavior. Results indicate that the fishers in the enforcement treatment group depleted the fish stock significantly faster than the unenforced control group. One possible explanation for this result is that the …

Investigations Of Thioether Generation For S-D-Ribosyl-L-Homocysteine Synthesis, Brendan Corcoran

Master's Theses

Creation of the thioether linkage is a fundamental step for the chemical preparation of the bacterial quorum sensing molecule S-D-ribosyl-L-homocysteine (SRH). Although previous preparations of SRH and its analogues have been reported in the literature, they employ assorted methods with varied results. Therefore, a reassessment of the methodology used for synthetic preparation of the thioether bond in SRH-like molecules is here considered. This work examines four methods of thioether generation following two mechanisms, bimolecular nucleophilic substitution (S_N2) and radical-initiated thiol-ene coupling, in an attempt to generate SRH in a more efficient and reproducible manner. Both mechanisms address …

Non-Ost Route Transition Interventions Among Injecting Drug Users In Kabul, Afghanistan: A Qualitative Feasibility Assessment Based On Institutional Stakeholders’ Views, William P. Tootle Jr

Master's Theses

An HIV epidemic threatens injecting drug users in Kabul, Afghanistan. Although opioid substitution therapy (OST) has been proven to reduce the spread of HIV and decrease injecting drug use in many parts of the world, including on a small scale in Afghanistan, political obstacles suggest that at this time it may not be a viable intervention there. In this thesis, therefore, I assess the feasibility of implementing an alternative to OST as an HIV-prevention strategy, namely, a non-OST route-transition intervention (RTI) designed to encourage and enable opiate users to switch from injecting to smoking (also called chasing). Based on semi-structured …

Effects Of Auditory And Visual Variability On Word Learning In Children: A Pilot Study, Kelly A. Casey

Master's Theses

For infants, acquiring vocabulary for nouns is a dynamic, complex process that involves pairing an auditory token with a visual referent. This process is computationally complex because the acoustic information produced for a verbal production of any given noun varies considerably due to factors including the person who is speaking, speaking rate, and linguistic context. Likewise, visual referents are also variable in characteristics such as size, shape, material, and color. Research suggests that variability in either the auditory or visual domains can facilitate early word learning. However, the role of simultaneous variability in these domains on noun learning remains unexplored. …
