Show morePolymer-derived ceramics (PDCs) are exceptional ultra-high temperature and stable multifunctional class of materials that can be synthesized from a polymer precursor through thermal decomposition. The presented research focuses on 1-D nanofibers, 2-D films and 3-D bulk, carbon-rich silicon carbon nitride (SiCN) ceramics. 1-D nanofibers were prepared via electrospinning for light weight, flame retardant and conductive applications. The commercially available CerasetTM VL20, a liquid cyclosilazane pre-ceramic precursor, was mixed with polyacrylonitrile (PAN) in order to make the cyclosilazane electrospinnable. Carbon-rich PDC nano?bers were fabricated by electrospinning various ratios of PAN/cyclosilazane solutions followed by pyrolysis. Surface morphology of the electro spun nanofibers characterized by SEM show PDC nano?bers with diameters ranging from 100-300 nm. Also, thermal stability towards oxidation showed a 10% mass loss at 623oC. 2-D carbon/SiCN films were produced by drop-casting a mixture of PAN/cyclosilazane onto a glass slide followed by pyrolysis of the film. Samples ranging from 10:1 to 1:10 PAN:cyclosilazane were made by dissolving the solutes into DMF to produce solutions ranging from 1% to 12% by weight. Green, heat-stabilized, and pyrolyzed 8% films were examined with FTIR to monitor the change in chemical structure at each step of the ceramization. SEM shows that high PAN samples produced films with ceramic embedded spheroid components in a carbon matrix, while high cyclosilazane samples produced carbon embedded spheroid.Finally, this research focuses on the challenge of making fully dense, 3-D bulk PDCs materials. Here we present a composite of SiCN with reduced graphene oxide (rGO) aerogels as a route for fully dense bulk PDCs. Incorporation of the rGO aerogel matrix into the SiCN has its pros and cons. While it lowers the strength of the composite, it allows for fabrication of large bulk samples and an increase in the electrical conductivity of the PDC. The morphology, mechanical, electrical properties and thermal conductivity of graphene-SiCN composite with varying rGO aerogel loading (0.3-2.4%) is presented. The high temperature stability, high electrical conductivity and low thermal conductivity of these composites make them excellent candidates for thermoelectric applications. Generally, carbon-rich SiCN composites with improved thermal and electrical properties are of great importance to the aerospace and electronics industries due to their expected harsh operating environments.

Show moreThis is an exploratory, qualitative study of female musicians and their experiences with discrimination in the music industry. Using semi-structured interviews, I analyze the experiences of nine women, ages 21 to 56, who are working as professional musicians, or who have worked professionally in the past. I ask them how they are treated differently based on their gender. Three forms of subtle discrimination are inferred from their narrative histories. First, female musicians are mistaken for non-musicians. They are encapsulated into inferior roles, like "the gimmick," "good for a girl," and "invisible accessory." Second, band mates and band managers control women's space, success, and artistic freedom. Third, their femininity, sexuality, and age are highly scrutinized. The analysis implies that female musicians are tokenized, devalued, and considered inappropriate for their jobs. Particular attention is paid to the similarities between female musicians and women in male dominated work places. I conclude by discussing the larger implications for gender, music, and social change in a sexist, unregulated industry.

Show moreThulium- and holmium-doped fiber lasers (TDF and HDF) emitting at 2 micron offer unique benefits and applications compared to common ytterbium-doped 1 micron lasers. This dissertation details the concepts, limitations, design, and performance of four 2 micron fiber laser systems. While these lasers were developed for various end-uses, they also provide further insight into two major power scaling limitations. The first limitation is optical nonlinearities: specifically stimulated Brillouin scattering (SBS) and modulation instability (MI). The second limitation is thermal failure due to inefficient pump conversion. First, a 21.5 W single-frequency, single-mode laser with adjustable output from continuous-wave to nanosecond pulses is developed. Measuring the SBS threshold versus pulse duration enables the Brillouin gain coefficient and gain bandwidth to be determined at 2 micron. Second, a 23 W spectrally-broadband, nanosecond pulsed laser is constructed for materials processing applications. The temporally incoherent multi-kW peak power pulses can also efficiently produce MI and supercontinuum generation by adjusting the input spectral linewidth. Third, the measured performance of in-band pumped TDF and HDF lasers are compared with simulations. HDF displays low efficiencies, which is explained by including ion clustering in the simulations. The TDF operates with impressive (>)90% slope efficiencies. Based on this result, a system design for (>)1 kW average power TDF amplifier is described. The designed final amplifier will be in-band pumped to enable high efficiency and low thermal load. The amplifier efficiency, operating bandwidth, thermal load, and nonlinear limits are modeled and analyzed to provide a framework for execution. Overall, this dissertation provides further insight and understanding on the various processes that limit power scaling of 2 micron fiber lasers.

An emissions inventory of VOCs, NOx, and CO2 was conducted for three central Florida counties Orange, Seminole, and Osceola (OSO) for calendar year 2008. The inventory utilized three programs: MOBILE6, NONROAD2005, and EDMS (Emissions and Dispersion Modeling System) to model on-road mobile, non-road mobile, and airport emissions, respectively.

Show moreAn emissions inventory of VOCs, NOx, and CO2 was conducted for three central Florida counties Orange, Seminole, and Osceola (OSO) for calendar year 2008. The inventory utilized three programs: MOBILE6, NONROAD2005, and EDMS (Emissions and Dispersion Modeling System) to model on-road mobile, non-road mobile, and airport emissions, respectively. Remaining point and area source data was estimated from the Florida Department of Environmental Protection (FDEP) and the U.S. Environmental Protection Agency's (U.S. EPA) 2008 emissions inventory. The previous OSO emissions inventory was done in 2002 and in the six years between inventories, there have been changes in population, commerce, and pollution control technology in central Florida which have affected the region's emissions. It is important to model VOC and NOx emissions to determine from where the largest proportions are coming. VOCs and NOx are ozone precursors, and in the presence of heat and sunlight, they react to form ozone (O3). Ozone is regulated by the U.S. Environmental Protection Agency through the FDEP. The current standard is 75 parts per billion (ppb) and Orange County's average is 71 ppb. A new standard (which will likely be about 65 ppb) is being developed and is scheduled to be announced by July 2011. If OSO goes into non-attainment, it will need to prepare a contingency plan for how to reduce emissions to submit to the FDEP for approval. The 2008 inventory determined that approximately 71,300 tons of VOCs and 59,000 tons of NOx were emitted that year. The majority of VOCs came from on-road mobile sources (33%) and area sources (43%), while the majority of NOx came from on-road mobile sources (64%) and non-road mobile sources (17%). Other major sources of VOCs included gasoline powered non-road mobile equipment (lawn and garden equipment), consumer solvents, cooking, and gasoline distribution. With the numbers that could be determined for CO2 emissions, on-road mobile and point sources were responsible for 93%. Of the point source CO2 emissions, almost all of it (87%) came from one large coal-fired power plant in Orange County.

Show moreMalaria afflicts about 500 million people worldwide thus causing significant global economic toll. The drugs available to treat the disease are rapidly losing their efficacy because of widespread prevalence of drug resistant parasites. Thus there is an urgent need to discover novel malaria therapeutics. This research is focused on to study the properties of a novel natural-like synthetic scaffold and analyze its selectivity, and cellular mechanism of action in Plasmodium falciparum. We have identified a novel compound, 3-amino-2-piperidinequinoline (APQ), which we termed UCF401. APQ demonstrated IC50 at submicromolar concentrations against Plasmodium falciparum using the SYBR Green-I fluorescence assay measuring cellular proliferation. This compound also demonstrated low cytotoxicity against the NIH3T3 and HEPG2 cells using MTS assays, showing an IC50 of 174 uM and 125 uM respectively, suggesting of excellent selectivity. We evaluated the compliance of APQ with Lipinski's parameters and determined the in vitro physicochemical profiles of the compound. Our results show that APQ is a Lipinski parameter compliant and has good physicochemical properties. The cellular mechanism of action of APQ was characterized through the assessment of the effects of the compound at different stages of the parasite's intraerythrocytic life cycle. This assay was done by treating a synchronized cell line with the compound at 5X the IC50 value and then imaging the cells at 12-hour intervals. We found that APQ arrests parasite development at the trophozoite stage. In addition we determined that APQ is parasitocidal after a 96 h exposure. These results demonstrate that APQ can be considered as a validated hit and/or early lead.

Show moreRadiation therapy has been successful in treating lung cancer patients, but its efficacy is limited by the inability to account for the respiratory motion during treatment planning and radiation dose delivery. Physics-based lung deformation models facilitate the motion computation of both tumor and local lung tissue during radiation therapy. In this dissertation, a novel method is discussed to accurately register 3D lungs across the respiratory phases from 4D-CT datasets, which facilitates the estimation of the volumetric lung deformation models. This method uses multi-level and multi-resolution optical flow registration coupled with thin plate splines (TPS), to address registration issue of inconsistent intensity across respiratory phases. It achieves higher accuracy as compared to multi-resolution optical flow registration and other commonly used registration methods. Results of validation show that the lung registration is computed with 3 mm Target Registration Error (TRE) and approximately 3 mm Inverse Consistency Error (ICE). This registration method is further implemented in GPU based real time dose delivery simulation to assist radiation therapy planning.

Show moreThis thesis explores the application of digital technologies in the creation of visionary or transformative artwork. The installation emphasizes number, color, symmetry, and the human form to create symbolic compositions patterned after ancient archetypes. Background research was done to inform the work through studies of the principles of visionary and transformative artwork as practiced by Ernst Fuchs, De Es Schwertberger, and Alex Grey. Connections between art and spirituality as explained by Kandinsky were studied to augment these principles. The sequence of artwork within the installation is comprised of both digital paintings and interactive triptych panels. To convey a sense of the mystical or sacred, the Rothko Chapel was used to inform the installation and serve as an artistic precedent. As the interactive work is created using realistically-modeled, computer generated characters, special consideration was given to understanding the "uncanny valley" and its potential effect in the interpretation of the installation. Interactivity is achieved through the use of ultrasonic sensors and Arduino prototyping boards.

Show moreBelieving that a thesis should encompass all aspects of a conservatory training program, I will write and perform--in collaboration with my classmate Patrick John Moran--a new musical entitled A 16 Bar Cut: The History of American Musical Theatre as the capstone project for my Master of Fine Arts in Musical Theatre. A 16 Bar Cut will be a two-man show that tells the entire history of American musical theatre from the ancient Greeks to today in a tongue-in-cheek manner. The goal of the project is to pay homage to an original American art form in a night of zany silliness and hilarity. The show will feature an informative perspective on the rise and current status of American musical theatre, several new songs, complete irreverence, and grown men singing, dancing, and making utter fools of themselves. Creating my thesis show will test and stretch my knowledge base of the musical theatre art form and virtually every skill that I have developed in my course of study. Since A 16 Bar Cut centers on the historical journey of musical theatre, constructing the new work will demonstrate my understanding of musical theatre history and literature. Performing the show will also challenge my ability and craftsmanship as an actor, singer, and dancer. Not only will I create a through-line character--a heightened, silly, professorial version of myself, but I will also create approximately fifty additional characters used throughout the show. The vocal and dance requirements for my track will also be numerous and demanding. And since the show travels through the major movements of musical theatre history, I will have to dance, sing, and act in the various styles and qualities of each movement and time period. Other significant challenges will center on script development. The first obstacle will be synthesizing music theatre into a single evening while maintaining an arc, storyline, and Patrick and my specific point of view about the genre. Another complexity to the show will be accessibility to the audience--how to be respectful to and informative about musical theatre, while at the same time being entertaining and funny to a wide array of audience members who will vary in musical theatre knowledge. In addition, developing a two-man thesis will require a complete collaboration with Patrick Moran. Since musical theatre is rarely--if ever--a solo art, working as a team will expand and exercise my collaborative abilities. And producing the show with Patrick will test supplementary skills such as marketing, resourcefulness, design and technical elements, etc. The Research and Analysis portion of my monograph document will be structured according to the M.F.A. Thesis Guidelines as applicable to my specific project. The (A) Research section will consist of a biographical glossary on all of the composers and lyricists referenced in A 16 Bar Cut. Librettists' information will be included when their work is pertinent. Additionally, each composer, lyricists, and librettists will be discussed in regards to their significance in musical theatre history. The (B) Structural Analysis section will describe the show's organization and construction and how the structural problems mentioned above are solved. The (C) Role Analysis section will have three sub-sections focusing on my different roles in the production as a playwright, producer, and actor.

Show moreA final thesis for my Master of Fine Arts degree should encompass every aspect of the past few years spent in the class room. Therefore, as a perfect capstone to my degree, I have decided to conceive, write, and perform a new musical with my classmate Rockford Sansom entitled The History of Musical Theatre: A 16 Bar Cut. The History of Musical Theatre: A 16 Bar Cut will be a two-man musical that will capsulate all of musical theatre history in a single evening. Starting with the Greeks and finishing in the present, the show will comedically inform the audience, while paying homage to, the astonishing art form called musical theatre, using several outrageous conventions such as a game show, spoof, mimicry, and most importantly, drag. The show will also pose the question to everyone: with all the great literature already created, where is musical theatre headed, and who is going to bring us there? Writing A 16 Bar Cut will test the training I have received and my mastery of musical theatre as an art form. The show will demonstrate my understanding and passion for several components used by authors and actors alike to create a musical. Being that the show is a capsulation of all musical theatre, A 16 Bar Cut will show my true mastery of the history and literature of musical theatre. I will be forced to hone my skills of the collaborative process at a new level, as never having to truly execute them with such intensity before. The challenges that lay ahead will be seen not only in the performance aspect, but also in the creation of A 16 Bar Cut. Since musical theatre has an immense range in genre and style, the ability to technically master these styles and genres will prove to challenge me as a performer, as well as a writer. In the performance, there will be three main challenges: vocal qualities, dance techniques, and my acting craft. The vocal styles used in A 16 Bar Cut will test my capabilities as a singer to meet the demands needed to convey the original material used as it was initially intended. As a dancer, the specific movements and "signatures" of the many choreographers will challenge me to understand and be able to re-create these "specifics" for an audience. The character building will test me as an actor, starting with one through-lined character--a heightened half-brained juvenile form of myself--along with building approximately fifty auxiliary characters throughout the show. As a writer, there are two major challenges that I foresee. The first challenge is the arc of the show--needing to keep a steady through-line that will let the audience understand what is happening and follow the history. The second obstacle is making sure the audience understands the show. I may be finishing an M.F.A. in Musical Theatre, but not everyone will be. In fact, some audience members may not know anything about musical theatre. This challenge arises trying to make the show funny to everyone, not just musical theatre dorks. The Research and Analysis portion of my monograph document will follow the course of action laid out in the M.F.A. Thesis Guidelines. The (A) Research section will include the biographical information pertaining to the composers and lyricists involved in the selected materials. Librettists of specific book shows that we choose to utilize as it pertains to our show will also be included in this section. I will also include a brief subsection of each composer, lyricist, and librettist's significance to musical theatre history. The (B) Structural Analysis section will discuss the structure and dramatic organization of how we choose to create A 16 Bar Cut. The (C) Analysis of the Role section will reveal how we employ the stock characters/ comedic duo of the straight man and funny man (i.e., Laurel & Hardy and Abbot & Costello). All other components outlined in the M.F.A. Thesis Guidelines will be included in my document.

Show moreThis thesis reports on the results of a mobile source emissions inventory for the University of Central Florida (UCF). For a large urban university, the majority of volatile organic compounds (VOC), oxides of nitrogen (NOx), and carbon dioxide (CO2) emissions come from on-road sources: personal vehicles and campus shuttles carrying students, faculty, staff, and administrators to and from the university, as well as university business trips. In addition to emissions from daily commutes, non-road equipment such as lawnmowers, leaf blowers, small maintenance vehicles, and other such equipment utilized on campus contributes to a significant portion to the total emissions from the university. UCF has recently become the second largest university in the nation (with over 56,000 students enrolled in the fall 2010 semester), and contributes significantly to VOC, NOx, and CO2 emissions in Central Florida area. In this project, students, faculty, staff, and administrators were first surveyed to determine their commuting distances and frequencies. Information was also gathered on vehicle type, and age distribution of the personal vehicles of students, faculty, administration, and staff as well as their bus, car-pool, and alternate transportation usage. The EPA approved mobile source emissions model, Motor Vehicle Emissions Simulator (MOVES2010a), was used to calculate the emissions from on-road vehicles, and UCF fleet gasoline consumption records were used to calculate the emissions from non-road equipment and on campus UCF fleet vehicles. The results of the UCF mobile source emissions inventory are reported and compared to a recently completed emissions inventory for the entire three-county area in Central Florida.

Show moreIncubators are organizations that have become a key factor to the success of new ventures. One study jointly sponsored by the University of Michigan, Ohio University, the National Business Incubation Association, and the Southern Technology Council found that 87% of the firms that went through an incubator program remain in business and 84% remain in their community. Clearly properly run incubators can provide much benefit. However there is littleconsensus on goals and best practices for managing the incubators themselves. Recently an approach to integrating strategy and practice called the balanced scorecard (BSC) has emerged asa popular tool in many public and private organizations.The purpose of this thesis is to examine the BSC as a potential performance andmanagement tool for Incubators in Florida. While the list of major corporations and public institutions that has adopted some form of a balanced scorecard continues to grow, there has been no research into its adaptability to incubators. This thesis found potential benefits associated with applying the BSC model to incubators, such as maintaining incubator's competitiveness and improving communication and employee's performance.Because a full-scale balanced scorecard system entails a fairly intensive implementation effort, it cannot be prescribed randomly across the variety of incubator enterprises. Accordingly, a stage of development framework is employed to help categorize incubators, assess their respective planning needs and identify how the balanced scorecard approach can be applied beneficially. Under these parameters, it is proposed that for incubators where both the degree of managerial complexity and the prospects for extensive change are high, the balanced scorecard can be a useful mechanism for effective management. A number of important implementation issues are also explored and some directions for future research are identified.

Show moreA Beautiful Belly is a feature-length, microbudget, digital motion picture produced, written, and directed by Andrew Kenneth Gay in pursuit of the Master of Fine Arts in Film & Digital Media from the University of Central Florida. The guiding question behind the production of A Beautiful Belly was whether digital "no budget" production was particularly suited to the telling of a particular kind of cinematic story - the interior journey. The pursuit of an intimate cinema shaped every decision by the filmmaker and his collaborators, and this thesis is a record of their production experience.

Recently, numerous high-profile instances of police misconduct and corruption have been thrust into the national spotlight. Hiring police officers who will act with integrity and not betray public trust remains essential. The present research experimentally examines this phenomenon by evaluating pre-employment assessment results against applicant performance on a simulated cheating task (i.e., The Dots Task) in order to derive information to improve contemporary pre-employment screening and...
Show moreRecently, numerous high-profile instances of police misconduct and corruption have been thrust into the national spotlight. Hiring police officers who will act with integrity and not betray public trust remains essential. The present research experimentally examines this phenomenon by evaluating pre-employment assessment results against applicant performance on a simulated cheating task (i.e., The Dots Task) in order to derive information to improve contemporary pre-employment screening and selection models. Four case examples are presented which depict malicious actors who possessed privileged access, assumed no one would ever scrutinize their activities, and attempted to leverage a lack of oversight for their personal benefit. A literature review of previous research findings is presented, and results from the current study are discussed. Spearman correlation analyses consistently indicated that participants who cheated were predisposed to moral disengagement via advantageous comparison. Participants who left all or part of their monetary award were less prone to general moral disengagement, particularly displacement of responsibility, while the opposite effect was observed for participants who took more than their earned award. Impression management was positively associated with stealing extra money, and cheating was more common among participants with elevated distorted thought patterns, including obsessional thinking, paranoid ideation, and alienation/perceptual distortion. Stepwise linear multiple regression analyses further substantiated the relationship between cheating and both distorted thought patterns and impression management, as well as provided evidence that (1) internalizing morality as part of one's self-identity and (2) warmth act as protective factors against cheating behavior. Positive relationships between cheating and distortion of consequences were also present within multiple regression analyses. Behavioral models produced from stepwise linear multiple regression analyses offer the potential to predict the likelihood and severity of cheating behavior that an individual may be predisposed to commit based upon their pre-employment assessment data, thereby enhancing pre-employment screening and selection decisions.

Physical bench top experiments are performed to validate and complement ongoing computational fluid dynamics (CFD) analyses of ventricular assist device (VAD) circulation. VADs are used in patients whose hearts do not function to their maximum potential due advanced stages of heart disease and, consequently, are unable to adequately supply blood to the systemic circulation.

Show morePhysical bench top experiments are performed to validate and complement ongoing computational fluid dynamics (CFD) analyses of ventricular assist device (VAD) circulation. VADs are used in patients whose hearts do not function to their maximum potential due advanced stages of heart disease and, consequently, are unable to adequately supply blood to the systemic circulation. VADs are commonly utilized as a bridge-to-transplantation, meaning that they are implanted in patients while waiting for a heart transplant. In such cases of long term utilization of VADs, it has been reported in the literatures that thrombo-embolic cerebral events occur in 14-47% of patients over the period of 6 to 12 months. This is a result of thrombus forming despite the use of anticoagulants and advances in VAD design. Accepting current rates of thrombo-embolisms, the main objective of the project is to identify and propose an optimal surgical cannula implantation orientation aimed at reducing the rate of thrombi reaching the carotid and vertebral arteries and thus reduce the morbidity and mortality rate associated with the long term use of VADs to patients suffering from advanced heart failure. The main focus of the experiment is on the physical aspect using a synthetic anatomically correct model constructed by rapid prototyping of the human aortic arch and surrounding vessels. Three VAD cannula implantation configurations are studied with and without bypass to the left carotid artery or to the Innominate artery with ligation of the branch vessel at its root. A mixture of water and glycerin serves to match blood viscosity measured with a rotating cone-plate viscometer. The Reynolds number in the ascending aorta is matched in the flow model. A closed loop mock circulatory system is then realized. In order to match the Reynolds number in the ascending aorta and LVAD cannula with that of the CFD model, a volumetric flow rate of 2.7 liters per minute is supplied through the synthetic VAD cannula and 0.9 liter per minute is supplied to the ascending aorta. Flow rates are measured using rotary flow meters and a pressure sensor is used to ensure a mean operating pressure of 100 mmHg is maintained. Synthetic acrylic blood clots are injected at the inlet of the VAD cannula and they are captured and counted at the vertebral and carotid arteries. The sizes of the thrombi simulated are 2, 3.5 and 5 mm which are typical of the range of diameters encountered in practice. Nearly 300 particles are released over 5 separate runs for each diameter, and overall embolization rates as well as individual embolization rates are evaluated along with associated confidence levels. The experimental results show consistency between CFD and experiment. Means comparison of thromboembolization rates predicted by CFD and bench-top results using a Z-score statistic with a 95% confidence level results in 22 of 24 cases being statistically equal. This study provides confidence in the predictive capabilities of the bench-top model as a methodology that can be utilized in upcoming studies utilizing patient-specific aortic bed model.
