Low-Level Programming Of A 9-Degree-Of-Freedom Wheelchair-Mounted Robotic Arm With The Application Of Different User Interfaces, Punya A. Basnayaka 2010 University of South Florida

Low-Level Programming Of A 9-Degree-Of-Freedom Wheelchair-Mounted Robotic Arm With The Application Of Different User Interfaces, Punya A. Basnayaka

Graduate Theses and Dissertations

Implementation of C++ and Matlab based control of University of South Florida's latest wheelchair-mounted robotic arm (USF WMRA-II), which has 9 degrees-of-freedom, was carried out under this Master's thesis research. First, the rotational displacements about the 7 joints of the robotic arm were calibrated. It was followed by setting the control gains of the motors. Then existing high-level programs developed using C++ and Matlab for USF WMRA-I were modified for WMRA-II. The required low-level programs to provide complete kinematics of the joint movements to the controller board of WMRA-II (Galil DMC-2183) were developed using C++. A test GUI ...


A Philosophical Inquiry On The Valuation And Selection Of Musical Materials For Culturally Diverse Learners In Global Environments, Jonathan Bassett 2010 University of South Florida

A Philosophical Inquiry On The Valuation And Selection Of Musical Materials For Culturally Diverse Learners In Global Environments, Jonathan Bassett

Graduate Theses and Dissertations

The selection of musical materials for use in the classroom is problematic. Since music educators have limited time with students, the inclusion of musical materials necessitates the perceived exclusion of other musical materials. This perception is due in part to the increasing diversity of students represented in the classroom, the cultural labeling of musical materials, the influence of multiculturalism on music education, and the influence of the Western aesthetic in music education. Since diverse groups can and do propose socially perceived valuations of these materials as critical for the inclusion of specific musical materials for use in the classroom, this ...


Upper Elementary Boys' Participation During Group Singing Activities In Single-Sex And Coeducational Classes, Zadda M. Bazzy 2010 University of South Florida

Upper Elementary Boys' Participation During Group Singing Activities In Single-Sex And Coeducational Classes, Zadda M. Bazzy

Graduate Theses and Dissertations

As boys in the upper elementary grades become increasingly influenced by peer pressure, many are less likely to participate in singing activities because singing is considered a "feminine" activity. The purpose of this research was to explore if there was an effect on upper elementary boys' level of participation during group singing activities when they attended music classes in a single-sex setting. This study employed a true experimental design and a mixed method. Boys (N = 186) were videotaped during their regular coeducational music classes on two occasions to establish baseline data. Then the students were randomly assigned to attend music ...


Re-Composition: Considering The Intersections Of Composition And Creative Writing Theories And Pedagogies, Danita Berg 2010 University of South Florida

Re-Composition: Considering The Intersections Of Composition And Creative Writing Theories And Pedagogies, Danita Berg

Graduate Theses and Dissertations

Maintaining composition studies and creative writing as discrete disciplines may not be in the best interests of either field. But so long as the majority of scholars and practitioners of either field remain largely uninformed about one another, it is unlikely that any progress toward conjoining the two fields will occur. Various important and constructive efforts have been made for more than thirty years to establish a scholarly, interdisciplinary community that dedicates itself to examining points of intersection between composition and creative writing. Initially, such efforts appear to attract the attention from the broader communities of each discipline. Before long ...


Design And Evaluation Of A Green Bittorrent For Energy-Efficient Content Distribution, Jeremy H. Blackburn 2010 University of South Florida

Design And Evaluation Of A Green Bittorrent For Energy-Efficient Content Distribution, Jeremy H. Blackburn

Graduate Theses and Dissertations

IT equipment has been estimated to be responsible for 2% of global CO2 emissions and data centers are responsible for 1.2% of U.S. energy consumption. With the large quantity of high quality digital content available on the Internet the energy demands and environmental impact of the data centers must be addressed. The use of peer-to-peer technologies, such as BitTorrent, to distribute legal content to consumers is actively being explored as a means of reducing both file download times and the energy consumption of data centers. This approach pushes the energy use out of the data centers and into ...


Architecture As Canvas, Monika Blazenovic 2010 University of South Florida

Architecture As Canvas, Monika Blazenovic

Graduate Theses and Dissertations

Cities are increasingly becoming vessels of consumption, while various opportunities for production of space and public expression are taken away from the city's inhabitants. New architectural interventions often disregard a site's previously developed character and further aid in wiping away memories closely related to a city's cultural past. Banja Luka, the second largest city of Bosnia and Herzegovina, has been an important cultural center, even through years of unrest. Within the city's main plaza stands an unfinished concrete structure (Fig. 3), built with pre-war conceptions of a hotel. The structure's location within the city of ...

Evaluating The Effectiveness Of The Travel Assistance Device On The Bus Riding Behavior Of Individuals With Disabilities, Arica J. Bolechala

Graduate Theses and Dissertations

Independence for individuals with disabilities can be facilitated through the use of devices that have been created and adapted for these individuals. Research regarding the use of technology to afford independence to those with disabilities is growing as new devices are being created. One such device is the Travel Assistance Device (TAD) which has undergone conceptual tests to assess if the individual components of the device work as intended. The purpose of this research study was to determine whether the prompts given by the TAD would exhibit stimulus control over the participant's behavior of pulling the cord to stop ...


Evaluation Assessment Of Metropolitan Ministries "Uplift U" Program And Preliminary Analysis Of Collected Data, Robert D. Bowers 2010 University of South Florida

Evaluation Assessment Of Metropolitan Ministries "Uplift U" Program And Preliminary Analysis Of Collected Data, Robert D. Bowers

Graduate Theses and Dissertations

Using the methodology and criteria put forth by the Juvenile Justice Evaluation Center (part of the Justice Research and Statistics Association, Washington D.C.), an assessment for evaluation of the Metropolitan Ministries "Uplift U" Program was conducted using review of data previously collected by Metropolitan Ministries, examination of documents provided by the organization, participant observation, and interviews with Metropolitan Ministry staff. This assessment reveals that there are significant problems in several areas that must be addressed before their program can be formally evaluated; including data collection and organization, outcomes measures, client selection standards, and how the program is portrayed as ...


Founding Fathers: An Ethnic And Gender Study Of The Iliadic Aeneid, Rob Brannon 2010 University of South Florida

Founding Fathers: An Ethnic And Gender Study Of The Iliadic Aeneid, Rob Brannon

Graduate Theses and Dissertations

In a 2005 work, Yasmin Syed concluded that the Aeneid created for ancient readers an idea of Romanness that was inclusive for all and not founded along strict genetic lines. Under this hypothesis, the Aeneid offers a sort of blueprint for becoming Roman, one in which biological descent from Aeneas is unnecessary. Syed reached this conclusion by analyzing themes of ethnicity and gender, in particular the ethnic other represented by the epic's female characters. This was accomplished in the manner so often chosen by Vergil scholars-by limiting analysis to the first half of the epic. The work concludes with ...


A Computational Kinematics And Evolutionary Approach To Model Molecular Flexibility For Bionanotechnology, Athina N. Brintaki 2010 University of South Florida

A Computational Kinematics And Evolutionary Approach To Model Molecular Flexibility For Bionanotechnology, Athina N. Brintaki

Graduate Theses and Dissertations

Modeling molecular structures is critical for understanding the principles that govern the behavior of molecules and for facilitating the exploration of potential pharmaceutical drugs and nanoscale designs. Biological molecules are flexible bodies that can adopt many different shapes (or conformations) until they reach a stable molecular state that is usually described by the minimum internal energy. A major challenge in modeling flexible molecules is the exponential explosion in computational complexity as the molecular size increases and many degrees of freedom are considered to represent the molecules' flexibility. This research work proposes a novel generic computational geometric approach called enhanced BioGeoFilter ...


A Case Study Of School-Based Leaders' Perspectives Of High School Dropouts, John J. Brown 2010 University of South Florida

A Case Study Of School-Based Leaders' Perspectives Of High School Dropouts, John J. Brown

Graduate Theses and Dissertations

School districts are failing to educate all of America's children. Dropout statistics reveal that almost 7,000 students leave our nation's schools everyday. At this rate 1.2 million students will not graduate on time with their prospective classes. The majority of American male students of African descent are dropping out instead of completing high school. When compared to that of their white peers, the dropout rate of American male students of African descent is significantly higher and the graduation rate much lower. This research examines high school dropouts from the perspectives of school-based leaders in a high ...


Self-Potential Response To Rainfall Changes Over Plugged And Unplugged Sinkholes In A Covered-Karst Terrain, Peter B. Bumpus 2010 University of South Florida

Self-Potential Response To Rainfall Changes Over Plugged And Unplugged Sinkholes In A Covered-Karst Terrain, Peter B. Bumpus

Graduate Theses and Dissertations

For the protection of wetland and water resources it would be beneficial to understand when collapse conduits function as recharge points to the underlying aquifer. Inexpensive, noninvasive methods to detect recharge are desirable. Previous studies show negative self-potential (SP) anomalies over sinkholes that correspond to the expected electrokinetic effects of groundwater flowing downward through a conduit. SP surveys are less labor-intensive than high-resolution 3D GPR and resistivity, and continuous long-term monitoring is possible. However, before SP surveys can be reliable indicators of flow, SP contributions from ET, conductivity changes, redox reactions, thermoelectric effects, cultural noise, and lateral flow must be ...


Faculty Perspectives On Doctoral Student Mentoring: The Mentor's Odyssey, Carol A. Burg 2010 University of South Florida

Faculty Perspectives On Doctoral Student Mentoring: The Mentor's Odyssey, Carol A. Burg

Graduate Theses and Dissertations

In recent years, mentoring has emerged as a research domain, however, the preponderance of mentoring research has been situated first, in the business or organizational settings and second, in the K-12 educational setting, focusing on protégé experiences, using quantitative survey instruments to collect data. Thus, mentoring research literature includes a paucity of formal studies in the arena of graduate education. Situated in the higher education setting, this study investigated the perspectives of faculty-mentors who provided mentoring to doctoral students who completed the doctoral degree, employing the qualitative research methodology known as phenomenology, as an orthogonal but complimentary epistemology to previous ...


System Identification In Automatic Database Memory Tuning, Tiffany Burrell 2010 University of South Florida

System Identification In Automatic Database Memory Tuning, Tiffany Burrell

Graduate Theses and Dissertations

Databases are very complex systems that require database system administrators to perform system tuning in order to achieve optimal performance. Memory tuning is vital to the performance of a database system because when the database workload exceeds its memory capacity, the results of the queries running on a system are delayed and can cause substantial user dissatisfaction. In order to solve this problem, this thesis presents a platform modeled after a closed control feedback loop to control the level of multi-query processing. Utilizing this platform provides two key assets. First, the system identification is acquired, which is one of two ...


Gadamer And Nagarjuna In Play: Providing A New Anti-Objectivist Foundation For Gadamer's Interpretive Pluralism With Nagarjuna's Help, Nicholas Byle 2010 University of South Florida

Gadamer And Nagarjuna In Play: Providing A New Anti-Objectivist Foundation For Gadamer's Interpretive Pluralism With Nagarjuna's Help, Nicholas Byle

Graduate Theses and Dissertations

Hans-Georg Gadamer rejects objectivism, the position that an interpreter may come to a single correct truth concerning any particular object, in favor of interpretive pluralism. What is not clear is how Gadamer grounds this position. This ambiguity leaves Gadamer open to multiple objectivist counters, ones which he would not wish to allow. The following argument, using a comparative and analytic approach, takes two concepts, pratityasamutpada(interdependence) and sunyata (emptiness), as they are deployed by Nagarjuna to provide Gadamer with this much needed anti-objectivist foundation. Specifically, the new foundation is anti-realist in which interpreters and objects of interpretation are metaphysically empty ...

Where Christ Dies Daily: Performances Of Faith At Orlando's Holy Land Experience, Sara B. Dykins Callahan 2010 University of South Florida

Where Christ Dies Daily: Performances Of Faith At Orlando's Holy Land Experience, Sara B. Dykins Callahan

Graduate Theses and Dissertations

This manuscript focuses on performances of place and faith inside the Holy Land Experience (HLE), an edutainment complex nestled in the fantasy nexus of Orlando, Florida. A self-proclaimed living-history museum, the HLE includes animatronic Bible characters and musical dramas. The HLE enacts and embodies evangelical narratives of Christianity and Christian faith, and visitors to the park are asked to join the performances, blurring the distinctions between spectators and professional actors. I argue that visitors' performances of faith invest the space of the HLE with sacredness, while the location and design of the HLE infuses the space with elements of the ...


Constraining The Geometry And Evolution Of The Maneadero Basin, Baja California, Mexico, Sean Callihan 2010 University of South Florida

Constraining The Geometry And Evolution Of The Maneadero Basin, Baja California, Mexico, Sean Callihan

Graduate Theses and Dissertations

The Maneadero Basin is identified as a transtensional sedimentary basin along the Agua Blanca Fault (ABF) in the southern limit to the "Big Bend" Domain of the North American-Pacific plate boundary zone. The ABF exhibits both the dextral and normal components of slip. This creates an interesting setting for the formation of the Maneadero Basin because structures with orientations similar to the ABF are typically contractional (e.g.: Puente Hills Fault, Whittier Fault, and Rancho Cucamonga Fault). The question if this basin is evidence of plate-scale transtension or local extension associated with bends/stopovers along the ABF is addressed by ...


Foraging Decisions Of Nocturnal Mice Under Direct And Indirect Cues Of Predation Risk, Robbin G. Capers 2010 University of South Florida

Foraging Decisions Of Nocturnal Mice Under Direct And Indirect Cues Of Predation Risk, Robbin G. Capers

Graduate Theses and Dissertations

The perception of increased predation risk by nocturnal mice and other small mammals has been shown to reduce activity levels, particularly in foraging effort. Various cues of predation risk have been used in previous studies, but few have assessed the potential interactions between different types of cues. I conducted field, laboratory, and enclosure experiments using predator scents, artificial light, and microhabitat variables to determine the effects of direct and indirect cues of predation risk on foraging behavior in wild nocturnal mice. Experimental foraging trays served as artificial resource patches, and giving-up densities were measured in order to test for foraging ...


Examining The Interface Between Alcohol Expectancies, Psychophysiological Reactivity To Alcohol Picture Cues, And Risk For Substance Use Disorders, Ashlee C. Carter 2010 University of South Florida

Examining The Interface Between Alcohol Expectancies, Psychophysiological Reactivity To Alcohol Picture Cues, And Risk For Substance Use Disorders, Ashlee C. Carter

Graduate Theses and Dissertations

The study examined the overlap between cognitive and affective measures of alcohol expectancies as they related to risk for developing alcohol use disorders. It was hypothesized that cognitive-based, paper-and-pencil measures and appetitive psychophysiological reactivity to alcohol cues would correlate and independently correlate to drinking behavior in a sample of college drinkers. It was also hypothesized that genetic risk would impact the relationship between upstream and downstream expectancy measures, given that children of alcoholics displayed blunted reactivity to appetitive cues. A sample of 137 college drinkers (67 males; mean age = 20.23 ± 1.61) reporting a range of drinking behavior (mean ...
