Some Construction Problems Related To The Incircle Of A Triangle, Amy B. Bell Jan 2006

Some Construction Problems Related To The Incircle Of A Triangle, Amy B. Bell

Electronic Theses and Dissertations 2000 - 2009

This thesis explores several construction problems related to the incircle of a triangle. Firstly, as a generalization of a theorem of D. W. Hansen, we find two quadruples of quantities related to a triangle which have equal sums and equal sums of squares. We also study the construction problems of triangles with centroid on the incircle, and those with a specified cevian - a median, an angle bisector, or an altitude- bisected by the incircle. Detailed analysis leads to designs of animation pictures using the dynamic software Geometer's Sketchpad.

Ubiquitous Entropy And Heat Death In Philip K. Dick And Pamela Zoline, Krista. Kasdorf Jan 2006

Ubiquitous Entropy And Heat Death In Philip K. Dick And Pamela Zoline, Krista. Kasdorf

Electronic Theses and Dissertations 2000 - 2009

My scientifically informed readings of Philip K. Dick's Ubik (1969) and Pamela Zoline's "The Heat Death of the Universe" (1967) consider entropy's multifarious meanings from both thermodynamics and information theory. Additionally, rather than relying upon overarching assumptions about the texts' cultural moment, I explore each fiction's presentation of entropy as negative or positive. For Dick, the loss of female mothering accelerates the heat death of late-capitalistic society, with entropy a negative, destructive force. Zoline, however, recognizes the injurious ramifications of entrapping women within the gender role of self-sacrificing wife/mother; her protagonist purposefully accelerates entropy production to destroy such a closed …

Vibration Tailoring Of Inhomogeneous Beams And Circular Plates, Demetris. Pentaras Jan 2006

Vibration Tailoring Of Inhomogeneous Beams And Circular Plates, Demetris. Pentaras

Electronic Theses and Dissertations 2000 - 2009

The vibrational behavior of inhomogeneous beams and circular plates is studied, utilizing the semi-inverse method developed by I. Elishakoff and extensively discussed in his recent monograph (2005). The main thread of his methodology is that the knowledge of the mode shape is postulated. The candidate mode shapes can be adopted from relevant static, dynamic or buckling problems. In this study, the exact mode shapes are sought as polynomial functions, in the context of vibration tailoring, i.e. designing the structure that possesses the pre-specified value. Apparently for the first time in the literature, several closed-form solutions for vibration tailoring have been …

Effect Of Age On Processing Family, Famous And Novel Faces: An Fmri Study, Lana Casey Jones

Electronic Theses and Dissertations 2000 - 2009

Facial recognition memory is a specialized system in the human brain, with an effect of familiarity playing a role in the brain activations involved. Previous studies examining the familiar face processing system have used college-aged subjects. However, memory disorders, like those associated with Alzheimer's disease, typically affect adults over sixty. In an attempt to reveal possible differences between young and older adults', two different age groups were subjected to fMRI analysis while viewing face images with varying familiarity (family, famous and novel). The result showed a significant difference in activations for various cortical areas including the precuneus, cingulate cortex, and …

Dynamical Perception: Modeling Framework, Model And Experiment, Felix Almonte Jan 2006

Dynamical Perception: Modeling Framework, Model And Experiment, Felix Almonte

Electronic Theses and Dissertations 2000 - 2009

Can a distributed anatomical and functional architecture serve as the basis for sufficiently complex perceptual phenomena? In addressing this question, the conceptual notion of dynamical system and its relation to other paradigms is considered including its definition. The principal goal is to develop a dynamical framework on which to ground the theoretical study of perception and other physical phenomena. As an entry point, the perceptual dynamics of auditory streaming are modeled using a neurally inspired dynamical model of auditory processing. Traditional approaches view streaming as a competition of streams, realized within a tonotopically organized neural network. In contrast, streaming can …

Euclid, The Van Hiele Levels, And The Geometer's Sketchpad, Elpida Thompson Jan 2006

Euclid, The Van Hiele Levels, And The Geometer's Sketchpad, Elpida Thompson

Electronic Theses and Dissertations 2000 - 2009

As an educator, my greatest concern is to provide my students with instruction that will raise their level of understanding in mathematics. For geometry in particular, the van Hiele Theory is a way to measure a student's level of geometric understanding. Geometry instruction that raises a student's van Hiele level can be enhanced with two important resources, the ancient text of Euclid's Elements a contemporary dynamic geometry software program like the Geometer's Sketchpad. Euclid's Elements can be read as a book of geometric constructions rather than a list of theorems neatly arranged in logical order. The Geometer's Sketchpad is a …

Frequency Line Tracking In Spectrograms Using Hidden Markov Models, Tuncay Gunes Jan 2006

Frequency Line Tracking In Spectrograms Using Hidden Markov Models, Tuncay Gunes

Electronic Theses and Dissertations 2000 - 2009

One of the limiting factors restricting aircraft landings at maJor airports is the minimum spacing requirements due to vortex wake avoidance. If it can be shown that the separation requirements are too conservative, then it may be possible to increase the rate of landings on a given runway. During August/September 2003, NASA and the (United States Department of Transportation) USDOT sponsored a wake acoustics test at the Denver International Airport. The central instrument of the test was a large microphone phased array. Different types of aircrafts were recorded during landing and the acoustic data obtained was stored. From acoustic data …

From Wise Woman To Mutilated Hag: Witchcraft Violence In Ghana, Laura A. Truxler Jan 2006

From Wise Woman To Mutilated Hag: Witchcraft Violence In Ghana, Laura A. Truxler

Electronic Theses and Dissertations 2000 - 2009

Gender based witchcraft violence in Ghana is one of the ways in which violence against women manifests itself in the society. Historical analysis of witchcraft in Africa is widely addressed in the literature, however, there is a comparative neglect of the gender dimensions of witchcraft violence and consequences for such women in terms of human rights violations. Within the northern agriculture regions of Ghana, the legitimacy of female land inheritance, in addition to government pressure to seek out western medical care instead of low-cost traditional herbalists, are threatening power structures and sparking witchcraft violence. Locating witchcraft violence in Ghana within …

Framing Bad Art: A Semiotic View Of Nathaniel Hawthorne's The Blithedale Romance, Scott B. Givonetti Jan 2006

Framing Bad Art: A Semiotic View Of Nathaniel Hawthorne's The Blithedale Romance, Scott B. Givonetti

Electronic Theses and Dissertations 2000 - 2009

Nathaniel Hawthorne's The Blithedale Romance has been criticized contemporaneously and subsequently by such figures as F. O. Matthiessen, Mark Van Doren, and Rudolph Von Abele for its lack of romanticism or realism, depending upon the critic. This thesis uses a semiotic approach to explore Hawthorne's deconstruction of his first-person narrator, Miles Coverdale, and the resulting confusion among critics regarding authorial control in what some call his "anti-romance." Coverdale, as a detached artist, is responsible for reality's misinterpretation and misrepresentation, somewhat lampooning Transcendentalism. The triadic relationship of object, sign, and interpretant modeled by Charles Sanders Peirce is discussed using Liszka, Sebeok, …

Global Feedback In Hierarchical Motion Pattern Formation, Stacey W. Brownlow Jan 2006

Global Feedback In Hierarchical Motion Pattern Formation, Stacey W. Brownlow

Electronic Theses and Dissertations 2000 - 2009

An array of four motion quartets (stimuli for which either horizontal or vertical motion is perceived depending on quartet aspect ratio) is arranged in a diamond configuration such that two global motion patterns are formed: (1) Rotation---alternating counterclockwise and clockwise motion is perceived, and (2) Parallel path motion---the perceived motions of all the elements are simultaneously horizontal or simultaneously vertical. The perception of rotation resulted in global feedback that biases the motion perceived for an individual component motion quartet to be more consistent with rotation than aspect ratio. Stronger rotation produced greater bias. Under certain conditions, the feedback-induced bias occurred …

Hamiltonian Methods In The Quantization Of Gauge Systems, Ruslan Vaulin Jan 2006

Hamiltonian Methods In The Quantization Of Gauge Systems, Ruslan Vaulin

Electronic Theses and Dissertations 2000 - 2009

The new formalism for quantization of gauge systems based on the concept of the dynamical Hamiltonian recently introduced as a basis for the canonical theory of quantum gravity was considered in the context of general gauge theories. This and other Hamiltonian methods, that include Dirac's theory of extended Hamiltonian and the Hamiltonian reduction formalism were critically examined. It was established that the classical theories of constrained gauge systems formulated within the framework of either of the approaches are equivalent. The central to the proof of equivalence was the fact that the gauge symmetries resuIt in the constraints of the first …

Impact Of Reading Instructional Methodology On Student Achievement Of Black Males Based On The Florida Comprehensive Assessment Test, Deedara. Hicks

Electronic Theses and Dissertations 2000 - 2009

For the past 20 years the gap in reading achievement has widened between Black and White students across the United States. The No Child Left Behind Act and the Florida A+ Plan require that all students meet proficiency on state-mandated assessments. As individual schools struggle to meet these guidelines, no student can be left behind. The purpose of this study was to determine the impact of two different reading instructional methodologies on the 2004 fourth-grade FCAT norm-referenced test (NRT) for Black males. The reading instructional methodologies examined in this study, Harcourt Basal Series and SRA Direct Instruction Program, have been …
