Stability Studies Of Cdte Solar Cells Fabricated With Varying Amounts Of Cu In The Back Contact, Swetha Erra

USF Tampa Graduate Theses and Dissertations

Solar energy is one of the abundant, non-polluting renewable energy options in our planet. During the last three decades considerable progress has been achieved in developing technologies to produce electricity from solar radiation, but producing electricity with low cost and low pollution is of concern. The CdTe solar cells are the leading source for the production of cost effective solar cells. The main issue of concern in these CdTe solar cells is degradation observed when stressed at elevated temperatures. The degradation in CdTe solar cells can be attributed to the back contact, which often contains Cu to improve the electronic …

Hybrid Model For Characterization Of Submicron Particles Using Multiwavelength Spectroscopy, Alicia Garcia-Lopez

USF Tampa Graduate Theses and Dissertations

The area of particle characterization is expansive; it contains many technologies and methods of analysis. Light spectroscopy techniques yield information on the joint property distribution of particles, comprising the chemical composition, size, shape, and orientation of the particles. The objective of this dissertation is to develop a hybrid scattering-absorption model incorporating Mie and Rayleigh-Debye-Gans theory to characterize submicron particles in suspension with multiwavelength spectroscopy.

Rayleigh-Debye-Gans theory (RDG) was chosen as a model to relate the particles joint property distribution to the light scattering and absorption phenomena for submicron particles. A correction model to instrument parameters of relevance was implemented to …

Multichannel Functional Data Decomposition And Monitoring, Hani Kababji

USF Tampa Graduate Theses and Dissertations

With current advances in sensors and information technology, online measurements of process variables become increasingly accessible for process control and monitoring. Such measurements may take the shape of curves rather than scalar values. The term Multichannel Functional Data (MFD) is used to represent the observations of multiple process variables in the shape of curves. Generally MFD contains rich information about processes. The challenge of process control in MFD is that Statistical Process Control (SPC) is not directly applicable. Furthermore, there is no systematic approach to interpret the complex variation in MFD. In this research, our objective is to develop an …

Characterization Of L-Cysteine Thin Films Via Photoemission Spectroscopy, Roy Gargagliano

USF Tampa Graduate Theses and Dissertations

Using photoemission spectroscopy (PES) the interface between the amino acid Lcysteine and a Au substrate was characterized to determine its electronic and chemical structure. L-cysteine was deposited on a Au substrate in several experiments via dipping into solution or via evaporation. The depositions were performed in several steps. Between deposition steps x-ray photoemission spectroscopy (XPS) and ultraviolet photoemission spectroscopy (UPS) measurements were taken. XPS was used to characterize the chemical interaction at the interface while UPS was used to determine the orbital line-up at the interface and the highest molecular orbital (HOMO) structure of L-cysteine. The results indicate the formation …

Performance Oriented Scheduling With Power Constraints, Brian C. Hayes

USF Tampa Graduate Theses and Dissertations

Current technology trends continue to increase the power density of modern processors at an exponential rate. The increasing transistor density has significantly impacted cooling and power requirements and if left unchecked, the power barrier will adversely affect performance gains in the near future. In this work, we investigate the problem of instruction reordering for improving both performance and power requirements. Recently, a new scheduling technique, called Forced Directed Instruction Scheduling, or FDIS, has been proposed in the literature for use in high level synthesis as well as instruction reordering [15, 16, 6]. This thesis extends the FDIS algorithm by adding …

Rational Fraction Approximations For Passive Network Functions, William Joel Dietmar Johnson

USF Tampa Graduate Theses and Dissertations

In electrical engineering, the designer is often presented with the problem of synthesizing a circuit for which the mathematical specifications are unsuitable for physical realization. Hence, the engineer must approximate as well as possible the prescribed network function by another function which is realizable. This paper describes a new approximation method for solving the problem of realizing passive network transfer functions, where the realization is carried out through the use of passive, reciprocal, lumped, linear, and time-invariant elements.

Optical Response Of Polycrystalline Mercuric Iodide Photoconductive Detectors, Prashant Chegoor

USF Tampa Graduate Theses and Dissertations

Mercuric Iodide in its tetragonal form has received a lot of attention for many years as a prospective room temperature X-ray and y-ray detector. Its basic properties are well suited for this purpose. Its wide band gap of 2.1eV contributes to a high dark resistivity of 10¹²ohm-cm or higher. A high atomic number of its constituent atoms (Hg-80, I -53) and a density of 6.3g/cm³ result in its efficient interaction with incident X-ray or y-ray radiation. Single crystalline mercuric iodide has been thoroughly studied and successfully utilized in commercial radiation detectors. But with the urgent need for …

Leakage Power Driven Behavioral Synthesis Of Pipelined Asics, Ranganath Gopalan

USF Tampa Graduate Theses and Dissertations

Traditional approaches for power optimization during high level synthesis, have targetted single-cycle designs where only one input is being processed by the datapath at any given time. Throughput of large single-cycle designs can be improved by means of pipelining. In this work, we present a framework for the high-level synthesis of pipelined datapaths with low leakage power dissipation. We explore the effect of pipelining on the leakage power dissipation of data-flow intensive designs. An algorithm for minimization of leakage power during behavioral pipelining is presented. The transistor level leakage reduction technique employed here is based on Multi-Threshold CMOS (MTCMOS) technology. …

Flood Forecasting Using Time Series Data Mining, Chaitanya Damle

USF Tampa Graduate Theses and Dissertations

Earthquakes, floods, rainfall represent a class of nonlinear systems termed chaotic, in which the relationships between variables in a system are dynamic and disproportionate, however completely deterministic. Classical linear time series models have proved inadequate in analysis and prediction of complex geophysical phenomena. Nonlinear approaches such as Artificial Neural Networks, Hidden Markov Models and Nonlinear Prediction are useful in forecasting of daily discharge values in a river. The focus of these methods is on forecasting magnitudes of future discharge values and not the prediction of floods. Chaos theory provides a structured explanation for irregular behavior and anomalies in systems that …

The Social Foundations Of Law, Martha Albertson Fineman

Faculty Articles

There are several important questions to ask both our politicians and ourselves as we seek to refine and further define an otherwise abstract commitment to substantive equality with which to replace our current formal version. As with many concepts of historic magnitude, some of the most significant questions to pose about equality have to do with how we should respond to evolutions in understanding and changes in aspiration for the term: ls a mere commitment to formal equality sufficient for a humane and modem state? How should the state respond to the fact that our society is increasingly one in …

But Who Is Any Longer Interested In The Possible?: Kathy Acker In Hell Failing Fuck You, Jake Kennedy

Reconstruction: Studies in Contemporary Culture

In 'But who is any longer interested in the possible?': Kathy Acker in Hell Failing Fuck You I explore and celebrate Acker's use of a tropics of failure (plagiarism, pain, terror, gender-play, bad jokes, dumbness) as an inimitable strategy for achieving counter-cultural art and community. The prose style and scholarly apparatus of my article reflect not only my position as a poet/academic but also attempt to model an ethical, non-authoritative, Acker-informed critical language.

Interracial Love, Virginians' Lies, And Donald Mccaig's Jacob's Ladder, Suzanne W. Jones

English Faculty Publications

The Old South's taboo against love between blacks and whites has cast a long shadow. No cross-racial relationship has been so pathologized by American society. Even in 1967, when the Supreme Court finally declared antimiscegenation laws unconstitutional in the case of Loving v. Virginia, sixteen states still prohibited interracial marriage, down from thirty states as recently as 1948. Not until 1998 and 2000 did ballot initiatives in South Carolina and Alabama finally eliminate the last of the antimiscegenation laws, although no one had tried to enforce them for years. Recent U.S. census figures show interracial unions increasing--up from 3 …

The Graveyard Of Genre: David Markson's Postmodern Epitaphs, Camelia Elias

Reconstruction: Studies in Contemporary Culture

David Markson is a writer who in a series of novels entitled Wittgenstein's Mistress (1988), Reader's Block (1996), and This is not a Novel (2001) explores some of our basic conceptions of genre. Can we call a book of fragments a novel? Is a novel still a novel when the characters are given names such as Author, Protagonist, Reader? What are we left with, when critics resort to labels such as novel of intellectual reference and allusion . . . minus the novel, or seminonfictional semifiction to categorise his texts? Through an apparently endless list of anecdotes and facts regarding …

One-Way Street In A Global City: Don Delillo And The Lugubrious Boredom Of The New Economy, Samuel Gerald Collins

Reconstruction: Studies in Contemporary Culture

[First paragraph]

few of the things we have fought against in cultural studies include the erroneous perceptions that the forces associated with globalization are 1) benefiting the world's peoples and 2) producing a homogeneous global culture. Against this, we have proffered endless texts documenting the sufferings of the world's peoples and critiquing the underlying assumptions regarding U.S. and Western hegemony as well as more hopeful tracts charting a more equitable future as an alternative to crushing regimes of neo-liberalism. In this, we have been joined by countless activists as well as others in women's studies, Latino/a studies, international relations and …

Molybdenum As A Back Contact For Cucl Treated Cds/Cdte Solar Cells, Matheshkumar Jayabal

USF Tampa Graduate Theses and Dissertations

CdTe is one of the most promising absorbers for use in inexpensive semiconductor solar cells having achieved a high efficiency of 16.4% in small area cells [1]. One of the most important technological problems in obtaining high efficiencies is to have a good ohmic contact on the CdTe, which is characterized by a very high work function [2]. Cu is used as a dopant in CdTe at the contact to promote quantum mechanical tunneling [3]. But the oversupply of Cu causes the diffusion of Cu through CdTe to the underlying CdS layer resulting in the degradation of the cell performance. …

Images Of God: The Effect Of Personal Theologies On Moral Attitudes, Political Affiliation, And Religious Behavior, Christoper Bader, Paul Froese

Sociology Faculty Articles and Research

Social scientists often explain religious effects in terms of religious group affiliations. Typically, researchers identify religious groups by denomination or some broader popular categorization, such as “fundamentalist” or “evangelical.” To capture religious differences more effectively, Steensland et al. (2000) propose an intricate classification of American denominations that takes into account the theology and historical development of various American religious traditions to predict individual attitudes and behaviors. We believe that equal care and attention should be devoted to the development of key measures of belief that may cross denominational lines. In this article, we propose one such measure: personal conceptions or …

Lo Family: Shoua Lo (Middle), Amy E. Smith

Hmong American Stories

Coming-of-age can happen abruptly, through a single experience—or it can be a process. For Shoua Lo, a cheerful man who laughs easily, the process began at age 19, when he decided to marry and start a family of his own. For Americans of all ethnicities, starting a family is a rite of passage that can open the door of adulthood. When you have children of your own, it is harder to continue to think of yourself as a child. Shoua, born the second oldest in a family of seven sons and three daughters, knew very well what sort of responsibilities …
