The purpose of this study is to verify and validate the dose at various points of interest in accelerated partial breast irradiation (APBI) treated with the Strut Adjusted Volume Implant (SAVI) applicator using Thermoluminescent Dosimeters (TLDs). A set of CT images were selected from a patient’s data who had received APBI using the SAVI applicator. The images were used to make 3D models. TLDs were calibrated for Brachytherapy. Various points of interest were marked out and slots were carved in the 3D models to fit the TLDs. CT scans were taken of the 3D models with expanded SAVI applicator inserted. A plan was made following B-39 protocol. The TLDs were read and the absorbed doses were calculated and compared to the delivered doses. The results of this study show that the overall average reading of the TLDs is within expected value. The TPS shows overestimated dose calculations for brachytherapy. / Includes bibliography. / Thesis (M.S.)--Florida Atlantic University, 2017. / FAU Electronic Theses and Dissertations Collection

Landfills receive odor complaints from local residents potentially resulting in legal ramifications and decreasing quality of life of the neighboring communities. However, analytical technologies to objectively measure odors in the field that will reflect human odor perceptions at a reasonable price do not currently exist. Hydrogen sulfide (H2S) is detectable by humans at low odor thresholds and may be one of the main nuisance odors emanating from landfills. For the first time, hOBPIIa complexed with 1- AMA has been used to detect H2S concentrations by spectrofluorometry. The optimal ratio of hOPBIIa-to-1-AMA was determined to be approximately 1:1. A strong linear regression model was generated to predict H2S concentrations from peak fluorescent emission intensity measurements within a range of 0-8.3 g of H2S. A novel experimental exposure chamber prototype was developed that has the potential to be incorporated into a portable sensor because it is compact. / Includes bibliography. / Thesis (M.S.)--Florida Atlantic University, 2017. / FAU Electronic Theses and Dissertations Collection

The unexpected comparison of a Supreme Court Justice with a popular culture icon demonstrates how politics and popular culture become entwined in the contemporary context; moreover, network culture provides a conduit for vernacular discourse about politics, which circulates in the style of popular culture. Through analysis of images of Ruth Bader Ginsburg as created, shared, and circulated in network culture, this project explores the alternative levels of discourse generated in network culture, examines the ways the public represents politics, and explains the ability of political subjects to affect meaning. The aim of this project is to document a conjunctural moment; as such, analysis of the images in aggregate provides a foundation to raise questions about how American political culture is manifested, attended to, and maintained through network culture and the parlance of popular culture. / Includes bibliography. / Thesis (M.A.)--Florida Atlantic University, 2017. / FAU Electronic Theses and Dissertations Collection

The Gulf Stream current in the Straits is typically dominated by a strong northerly current, associated shear, and eddies. The water column also includes a prominent thermocline and periodically features internal waves centered on the upper or lower edges of the thermocline. Despite numerous previous related studies, there is limited available field data on internal waves in the Straits of Florida. Here, study and analysis of velocity, temperature and conductivity data acquired in the Straits over a period of time are described, in support of identifying presence of internal waves in the flow. A systematic procedure is employed in modifying the universal Garrett- Munk spectrum for internal waves in the open ocean for application to flow in the Straits of Florida. Using this process, identified internal waves are characterized and related velocity fluctuations in the time series are isolated to facilitate consideration of their correlations with simultaneously observed magnetic fields. / Includes bibliography. / Thesis (M.S.)--Florida Atlantic University, 2017. / FAU Electronic Theses and Dissertations Collection

When unidentified skeletal remains are found, researchers utilize a number of methods to apportion details for a biological profile. While these practices are used and professed through generations of students, they also require a reevaluation of the methods. This project estimates the ancestry and sex of nine unknown skeletal individuals through two different mechanisms. Modified biological profiles were completed through two different methodologies: anthroscopic traits (Buikstra and Ubelaker 1994; White et al. 2012) and geometric morphometrics using 3D-ID (Slice and Ross 2009). The results serve two purposes: (1) to provide ancestry and sex (2) to compare two methodologies through outcomes and repeatability of results. Intra-observer error testing was conducted on both methods. All outputs resulted in low intra-rater reliability, highlighting the repeatability error in one observer’s collection methods. These results conclude and encourage the reevaluation and standardization of the procedures and comparison groups used to assess ancestry and sex. / Includes bibliography. / Thesis (M.A.)--Florida Atlantic University, 2017. / FAU Electronic Theses and Dissertations Collection

Elevated yolk progesterone has been shown to impair prenatal, but facilitate postnatal auditory learning in bobwhite quail chicks. Elevated yolk testosterone has facilitated prenatal learning, but its effects on postnatal auditory learning in quail are unknown. Either testosterone or an oil vehicle was injected into bobwhite quail eggs prior to incubation. Control eggs were unmanipulated. Following hatching, chicks were exposed to a conspecific maternal call (A or B) for 240 min. At 48 hr, chicks were tested for their preference for the familiarized vs. novel call. All groups demonstrated a preference for the familiar call (p < .05), but minimal between group difference were found. Contrary to previous research, elevated yolk testosterone neither facilitated nor impaired postnatal auditory learning in bobwhite quail chicks. Further research will examine underlying mechanisms responsible for differential effects and explore if similar systems are involved in other species-typical processes such as social motivation. / Includes bibliography. / Thesis (M.A.)--Florida Atlantic University, 2017. / FAU Electronic Theses and Dissertations Collection

In this research, a new reputation-based model is utilized to disincentivize collusion of defenders and attackers in Software Defined Networks (SDN), and also, to disincentivize dishonest mining strategies in Blockchain. In the context of SDN, the model uses the reputation values assigned to each entity to disincentivize collusion with an attacker. Our analysis shows that not-colluding actions become Nash Equilibrium using the reputationbased model within a repeated game setting. In the context of Blockchain and mining, we illustrate that by using the same socio-rational model, miners not only are incentivized to conduct honest mining but also disincentivized to commit to any malicious activities against other mining pools. We therefore show that honest mining strategies become Nash Equilibrium in our setting. This thesis is laid out in the following manner. In chapter 2 an introduction to game theory is provided followed by a survey of previous works in game theoretic network security, in chapter 3 a new reputation-based model is introduced to be used within the context of a Software Defined Network (SDN), in chapter 4 a reputation-based solution concept is introduced to force cooperation by each mining entity in Blockchain, and finally, in chapter 5, the concluding remarks and future works are presented. / Includes bibliography. / Thesis (M.S.)--Florida Atlantic University, 2017. / FAU Electronic Theses and Dissertations Collection

Contemporary educational trends have created a false dichotomy between the arts and science. The will to make STEM subjects the focus of K-12 education, ignores both a shared history and the potential for greater learning in a shared future.The intention of Points of Intersection is to demonstrate that design, science and math intersect in their concepts, practices and history. In the past, these disciplines were explored and studied together and benefited from each other. By exploring what design and science have in common and the points where they intersect, we can see the relevance and importance of art and design in k-12 education and change STEM to STEAM. The exhibition will explore point, line, plane and the “Golden Ratio” demonstrating how these concepts can be understood from the perspectives of physics, math, art and design on a basic level. These basic principles can be used to introduce these fields of study and bring a better understanding of them to students in K-12. Future designers and scientists with this educational underpinning will have a better mutual understanding of one another’s field and the potential for shared research, process and results. / Includes bibliography. / Thesis (M.F.A.)--Florida Atlantic University, 2017. / FAU Electronic Theses and Dissertations Collection

The primary objective of this research is to investigate the viability of magnetic anomaly localization with an autonomous underwater vehicle, using a genetic algorithm (GA). The localization method, first proposed by Sheinker. et al. 2008, is optimized here for the case of a moving platform. Extensive magnetic field modeling and algorithm simulation has been conducted and yields promising results. Field testing of the method is conducted with the use of the Ocean Floor Geophysics Self-Compensating Magnetometer (SCM). Extensive out-of-water field testing is conducted to validate the ability to measure a target signal in a uniform NED frame as well as to validate the effectiveness of the GA. The outcome of the simulation closely matches the results of the conducted field tests. Additionally, the SCM is fully integrated with FAU’s Remus 100 AUV and preliminary in-water testing of the system has been conducted. / Includes bibliography. / Thesis (M.S.)--Florida Atlantic University, 2017. / FAU Electronic Theses and Dissertations Collection

This thesis examines gay student organizing to understand the role of college students in the burgeoning lesbian and gay movement of the 1970s. Although students are widely recognized as participants in gay activism in this period, few studies have attempted to explore their particular role. The Gay Academic Union (GAU) at Florida Atlantic University in Boca Raton, FL, is presented as a case study, using archival and oral history research. Lesbian and gay students participated in the construction of a new political strategy based on visibility and community, which positioned “coming out” as its central metaphor. During the early to mid-1970s, students were especially well positioned to play a role in the gay movement, which relied on small, local organizations to spread gay politics throughout the nation. However, in the wake of the Anita Bryant-led effort to repeal Miami-Dade’s gay rights ordinance in 1977, the growth of national gay organizations and a national media discourse on homosexuality began to eclipse the type of organizing at which college students had excelled. By extending the narrative of gay organizing in the 1970s outside of urban centers, the story of the GAU at Florida Atlantic demonstrates that college students played a crucial part in disseminating the new forms of gay identity and culture associated with the gay movement.
