Cdte/Cds Thin Film Solar Cells Fabricated On Flexible Substrates, Vasilios Palekis

USF Tampa Graduate Theses and Dissertations

Cadmium Telluride (CdTe) is a leading thin film photovoltaic (PV) material due to its near ideal bandgap of 1.45 eV and its high optical absorption coefficient. The typical CdTe thin film solar cell is of the superstrate configuration where a window layer (CdS), the absorber (CdTe) and a back contact are deposited onto glass coated with a transparent electrode.

Substrate CdTe solar cells where the above listed films are deposited in reverse are not common. In this study substrate CdTe solar cells are fabricated on flexible foils.

The properties of the Molybdenum back contact, Zinc Telluride (ZnTe) interlayer and CdTe …

Knowledge Guided Non-Uniform Rational B-Spline (Nurbs) For Supporting Design Intent In Computer Aided Design (Cad) Modeling, Khairan Rajab

USF Tampa Graduate Theses and Dissertations

For many years, incompatible computer-aided design (CAD) packages that are based on Non-uniform Rational B-Spline (NURBS) technology carried out the exchange of models and data through either neutral file formats (IGES or STEP) or proprietary formats that have been accepted as quasi industry standards. Although it is the only available solution at the current time, the exchange process most often produces unsatisfactory results. Models that are impeccable in the original modeling system usually end up with gaps or intersections between surfaces on another incompatible system. Issues such as loss of information, change of data accuracy, inconsistent tolerance, and misinterpretation of …

Autonomous Mobility And Manipulation Of A 9-Dof Wmra, William Garrett Pence

USF Tampa Graduate Theses and Dissertations

The wheelchair-mounted robotic arm (WMRA) is a 9-degree of freedom (DoF) assistive system that consists of a 2-DoF modified commercial power wheelchair and a custom 7-DoF robotic arm. Kinematics and control methodology for the 9-DoF system that combine mobility and manipulation have been previously developed and implemented. This combined control allows the wheelchair and robotic arm to follow a single trajectory based on weighted optimizations. However, for the execution of activities of daily living (ADL) in the real-world environment, modified control techniques have been implemented.

In order to execute macro ADL tasks, such as a "go to and pick up" …

Mining Associations Using Directed Hypergraphs, Ramanuja N. Simha

USF Tampa Graduate Theses and Dissertations

This thesis proposes a novel directed hypergraph based model for any database. We introduce the notion of association rules for multi-valued attributes, which is an adaptation of the definition of quantitative association rules known in the literature. The association rules for multi-valued attributes are integrated in building the directed hypergraph model. This model allows to capture attribute-level associations and their strength. Basing on this model, we provide association-based similarity notions between any two attributes and present a method for finding clusters of similar attributes. We then propose algorithms to identify a subset of attributes known as a leading indicator that …

Administrators of the the portal have the ability to form the portal in such a way to mimic the existing structure of their company. Access rights to the applications in the portal may be granted or denied per division and the users of the portal are placed in these divisions based on their duty in the company. In addition, users are granted roles which dictate their ability to …

Heterogeneous Modeling Of Medical Image Data Using B-Spline Functions, Olya Grove

USF Tampa Graduate Theses and Dissertations

Ongoing developments in the field of medical imaging modalities have pushed the frontiers of modern medicine and biomedical engineering, prompting the need for new applications to improve diagnosis, treatment and prevention of diseases.

Biomedical data visualization and modeling rely predominately on manual processing and utilization of voxel and facet based homogeneous models. Biological structures are naturally heterogeneous and in order to accurately design and biomimic biological structures, properties such as chemical composition, size and shape of biological constituents need to be incorporated in the computational biological models.

Our proposed approach involves generating a density point cloud based on the intensity …

Utilizing Probabilistic Reinforcement To Enhance Participation In Parent Training, Errity Jones

USF Tampa Graduate Theses and Dissertations

Parental participation in parent training programs is necessary for success in behavioral parent training. Prior literature has demonstrated probabilistic reinforcement as an effective intervention for improving a wide variety of behaviors. In the present study, a probabilistic reinforcement program (i.e., lottery) was implemented in order to evaluate its efficacy as part of a behavioral parent training program. The behaviors targeted for increase included attendance, participation, homework completion, and performing role-plays or completing in-class assignments for two 10 week Tools for Positive Behavior Change courses. Participants earned lottery tickets for each of the dependent measures, and drawings took place at the …

Stress-Strain Management Of Heteroepitaxial Polycrystalline Silicon Carbide Films, Christopher William Locke

USF Tampa Graduate Theses and Dissertations

Silicon carbide (SiC) is one of the hardest known materials and is also, by good fortune, a wide bandgap semiconductor. While the application of SiC for high-temperature and high-power electronics is fairly well known, its utility as a highly robust, chemically-inert material for microelectrical mechanical systems (MEMS) is only beginning to be well recognized. SiC can be grown on both native SiC substrates or on Si using heteroepitaxial growth methods which affords the possibility to use Si micromachining methods to fabricate advanced SiC MEMS devices.

The control of film stress in heteroepitaxial silicon carbide films grown on polysilicon-on-oxide substrates has …

Nonvoters: Doing Nothing To Change The Government They Hate, Geoffrey N. Mciver

Political Science Theses and Capstones

The sporadic and often dismal voter turnout of the American public is often regarded as a hole in the democratic model. This research examines the influence of an individual‘s attitude about their government and how it affects their voting habits. Literature in the past has isolated demographic makeup as the reason for nonvoting, i.e. education or income. However, the nonvoter‘s state of mind in relation to their general feelings toward government and the social contract has been broadly overlooked. A new measure of an individual‘s attitude toward government was created using a collection of survey questions centered on a person‘s …

Introduction To Willa Cather And Modern Cultures [Cather Studies 9], Melissa J. Homestead

Department of English: Faculty Publications

To some, linking Willa Cather to "the modern" or more narrowly to literary modernism still seems an eccentric proposition. As Richard Millington has pointed out, "one will look in vain for Cather's name in the index of most accounts, whether new or old, of the nature and history of Anglo-American modernism" (52). Perhaps she fails to feature in these accounts because in her public pronouncements and certain recurring motifs in her fiction, she appeared to turn her back on modernity. Cather was skeptical about many aspects of the culture that took shape around her in the early decades of the …

Decision Aid Models For Resource Sharing Strategies During Global Influenza Pandemics, Alfredo Santana Reynoso

USF Tampa Graduate Theses and Dissertations

Pandemic influenza outbreaks have historically entailed significant societal and economic disruptions. Today, our quality of life is threatened by our inadequate preparedness for the imminent pandemic. The key challenges we are facing stem from a significant uncertainty in virus epidemiology, limited response resources, inadequate international collaboration, and the lack of appropriate science-based decision support tools. The existing literature falls short of comprehensive models for global pandemic spread and mitigation which incorporate the heterogeneity of the world regions and realistic travel networks. In addition, there exist virtually no studies which quantify the impact of resource sharing strategies among multiple countries. This …

Tarnished Golden Years: Older Offenders With Mental Health Problems And Late Life First Time Offenders, Brianne Stanback

USF Tampa Graduate Theses and Dissertations

Older offenders (offenders 50 years and older) are a distinct groups within the U.S. correctional system. Studies 1 and 2 were intended to investigate mental health and stressors among jailed older offenders.

Study 1 examined the prevalence rates of mental health disorders and explored the relationship between mental health disorders and stressors. Participants 50 years and older (N=330) from the 2002 wave of the Survey of Inmates in Local Jails (SILJ) were studied via descriptive analysis, factor analysis, and a logistic regression to determine which variables were related to the probability of having a mental health problem. 65.8% of participants …

Patient Safety In Nursing Homes, Kali Thomas

USF Tampa Graduate Theses and Dissertations

Safety of residents has gained increased popularity in recent years following a report from the Institute of Medicine attributing 98,000 hospital deaths each year to errors by staff. As a result, regulatory agencies, advocates, and health care providers have shifted their focus to understanding patient safety and developing a culture that promotes safety. However, nursing homes lag behind other health care providers in their adoption of a patient safety culture and understanding what factors affect safety in resident care. These insights are needed to ensure that nursing home residents receive the safe care.

The purpose of this dissertation is to …

“Born Again Hard”: Sexualized Violence In The Creation Of American Warriors, Katherine Highfill

The Journal of Undergraduate Research

Cultures are built upon myths that reinforce and glorify the way citizens wish to view themselves as part of a larger, stronger whole. These myths are central to the strength of a culture due to the shared sense of greatness, responsibility, and cohesion mutual belief instills. Globally, examples of cultural myth include French elegance, Arabic divine religious sanction, and British diplomatic proficiency. Specifically American mythology includes the pioneer mentality, equality for all citizens, and global caretaker. These myths, as with those of other countries, were born of historic actuality or ideology. The basis for each of these American myths, however, …
