Humdrum Aha!, Dana Odwazny Pell Jan 2012

Humdrum Aha!, Dana Odwazny Pell

Electronic Theses and Dissertations 2010 - 2019

Following the work of Sara Houghton-Walker and Edward Strickland, this thesis theorizes the "mundane sublime" as encountered in romanticist John Clare's poetry. Instead of being oriented upward, as with Longinus's elevatory sublime, Clare's mundane sublime brings the subject downward to earth. While the sublime of the Burkean tradition begins with terror, I claim that the mundane sublime emerges out of love for that which is commonplace. Still revelatory, it may be further characterized by an engagement with ecosystems, eternity, divinity, and nature as a whole. Clare's style scaffolds images resulting in a profusion of detail that arrests the mind and …

Internal Waves On A Continental Shelf, Arjun. Jagannathan Jan 2012

Internal Waves On A Continental Shelf, Arjun. Jagannathan

Electronic Theses and Dissertations 2010 - 2019

In this thesis, a 2D CHebyshev spectral domain decomposition method is developed for simulating the generation and propagation of internal waves over a topography. While the problem of stratified flow over topography is by no means a new one, many aspects of internal wave generation and breaking are still poorly understood. This thesis aims to reproduce certain observed features of internal waves by using a Chebyshev collation method in both spatial directions. The numerical model solves the inviscid, incomprehensible, fully non-linear, non-hydrostatic Boussinesq equations in the vorticity-streamfunction formulation. A number of important features of internal waves over topography are captured …

Proud Elastic Target Discrimination Using Low-Frequency Sonar Signatures, Brenton. Mallen Jan 2012

Proud Elastic Target Discrimination Using Low-Frequency Sonar Signatures, Brenton. Mallen

Electronic Theses and Dissertations 2010 - 2019

This thesis presents a comparative analysis of various low-frequency sonar signature representations and their ability to discriminate between proud targets of varying physical parameters. The signature representations used include: synthetic aperture sonar (SAS) beamformed images, acoustic color plot images, and bispectral images. A relative Mean-Square Error (rMSE) performance metric and an effective Signal-to-Noise Ratio (SNReff) performance metric have been developed and implemented to quantify the target differentiation. The analysis is performed on a subset of the synthetic sonar stave data provided by the Naval Surface Warfare Center - Panama City Division (NSWC-PCD). The subset is limited to aluminum and stainless …

Principals' Knowledge Of Special Education Policies And Procedures, Lindsay. Jesteadt Jan 2012

Principals' Knowledge Of Special Education Policies And Procedures, Lindsay. Jesteadt

Electronic Theses and Dissertations 2010 - 2019

Research has shown that most school leaders lack the knowledge necessary to deal with the many different aspects and issues that special education programs encompass. This lack of knowledge ultimately places special education teachers, programs, and students with disabilities at a clear disadvantage. With The No Child Left Behind Act (NCLB) of 2001 and the reauthorization of The Individuals with Disabilities Education Improvement Act (IDEA) in 2004, schools and school leaders are being held accountable for the learning gains of all students, including students with disabilities. This study sought to assess the knowledge of Florida school principals in the area …

Reducing Impedance Mismatch In Sql Embeddings For Object-Oriented Programming Languages, Jose Luis Hurtado Jan 2012

Reducing Impedance Mismatch In Sql Embeddings For Object-Oriented Programming Languages, Jose Luis Hurtado

Electronic Theses and Dissertations 2010 - 2019

We survey and compare the different major mechanisms for embedding the relational database language SQL in object-oriented programming languages such as Java and C#, with regard to how much impedance mismatch these embeddings suffer. Here impedance mismatch refers to clarity and performance difficulties that arise because of the nature of the embedding. Because of the central position in the information technology industry of object-oriented programs that access SQL-based relational database systems, reducing impedance mismatch is generally recognized in that industry as an important practical problem. We argue for the suitability of SQL as a database language, and hence for the …

Revisiting The Methodology And Application Of Value-At-Risk, Kyong. Chung Jan 2012

Revisiting The Methodology And Application Of Value-At-Risk, Kyong. Chung

Electronic Theses and Dissertations 2010 - 2019

The main objective of this thesis is to simulate, evaluate and discuss three standard methodologies of calculating Value-at-Risk (VaR) : Historical simulation, the Variance-covariance method and Monte Carlo simulations. Historical simulation is the most common nonparametric method. The Variance-covariance and Monte Carlo simulations are widely used parametric methods. This thesis defines the three aforementioned VaR methodologies, and uses each to calculate 1-day VaR for a hypothetical portfolio through MATLAB simulations. The evaluation of the results shows that historical simulation yields the most reliable 1-day VaR for the hypothetical portfolio under extreme market conditions. Finally, this paper concludes with a suggestion …

Rings Of Integer-Valued Polynomials And Derivatives, Yuri. Villanueva Jan 2012

Rings Of Integer-Valued Polynomials And Derivatives, Yuri. Villanueva

Electronic Theses and Dissertations 2010 - 2019

For D an integral domain with field of fractions K and E a subset of K, the ring Int (E,D) = {f e K[X]lf (E) C D} of integer-valued polynomials on E has been well studies. In particulare, when E is a finite subset of D, Chapman, Loper, and Smith, as well as Boynton and Klingler, obtained a bound on the number of elements needed to generate a finitely generated ideal of Ing (E, D) in terms of the corresponding bound for D. We obtain analogous results for Int (r) (E, D) - {f e K [X]lf(k) (E) c D …

Understanding The Emission From Semiconductor Nanoparticles, Beth Ann Manhat Jan 2012

Understanding The Emission From Semiconductor Nanoparticles, Beth Ann Manhat

Dissertations and Theses

This dissertation describes the synthesis and characterization of fluorescent semiconductor nanoparticles (NPs) in order to optimize their biomedical utility for imaging and sensing applications. While both direct and indirect bandgap semiconductor NPs have been studied, control over their emission properties vary. Quantum confinement (QC), which primarily controls the emission wavelength of nanosized semiconductors, dictates that as the size of semiconductor NPs decrease, the magnitude of the bandgap increases, resulting in changes in the observed emission wavelength: smaller NPs have a larger bandgap, and thus a bluer emission. However, surface, interfacial, or shell defects can act as non-radiative or radiative recombination …

Designing Wise Communities That Engage In Creative Problem Solving: An Analysis Of An Online Design Model, Charlotte Nirmalani Gunawardena, Ludmila Layne, Casey Frechette Jan 2012

Designing Wise Communities That Engage In Creative Problem Solving: An Analysis Of An Online Design Model, Charlotte Nirmalani Gunawardena, Ludmila Layne, Casey Frechette

University Libraries & Learning Sciences Faculty and Staff Publications

Addressing the conference theme of “design thinking,” this paper discusses an instructional design model, WisCom (Wisdom Communities) that we developed to build a wise learning community online, to solve open-ended, ill-structured problems such as solving a health crisis or an environmental disaster, which requires the exchange of multiple perspectives, inter-disciplinary thinking, creative problem solving, and social construction of knowledge. Based on socio-constructivist, sociocultural theories of learning and mediated cognition (Vygotsky, 1978), distributed cognition (Hutchins, 1995; Pea, 1993), group cognition (Stahl, 2006), research on how people learn (Bransford, Vye, Bateman, Brophy, & Roselli, 2004), and distance education design principles (Moore & …
