Date: August 2010
Creator: Lyons, Renée Kathleen
Description: This two-part thesis includes a critical preface and a collection of my poems. Using three poems-Louise Glück's "Lullaby," Bob Hicok's "Poem for My Mother's Hysterectomy," and Nick Flynn's "Memento Mori"-the critical preface examines how, in poetry, the transformation of a body negotiates trauma and triggers a conceptual shift, the creation and revision of identity, and the release of the duende's inspirational force. The collection of poetry that follows seeks to transfigure the body as a way to explore the nuanced traumas of human experience.

Description: This study traces the history and culture of Spain as seen through the lens of the nation´s production of horror cinema. Starting from the boom of Spanish horror film in the early 1960s, the thesis compares and contrasts the political and social aspects of Spanish society throughout three distinct eras of the 20th century: 1962 – 1975 (the boom of Spanish horror film through the Franco dictatorship), 1975 – 1999 (the transition to democracy through the end of the 20th century) and 2000 – present (the 21st century). Movies as diverse as Gritos en la noche (1962, Jesús Franco), ¿Quién puede matar a un niño? (1976, Narciso Ibáñez Serrador) and Angustia (1987, Bigas Luna) are framed by culturally-related anectodes as well as correlations to their respective social environments. Special attention has been paid to the production and release of each film, especially in regards to censorship during the Franco dictatorship. The results show that Spanish horror cinema has acted as a true mirror to culture, society and politics in its native country throughout the 20th century and that this trend will likely extend in to the future.

A Comprehensive Modeling Framework for Airborne Mobility

A Comprehensive Modeling Framework for Airborne Mobility

Creator: Xie, Junfei
Description: Mobility models serve as the foundation for evaluating and designing airborne networks. Due to the significant impact of mobility models on the network performance, mobility models for airborne networks (ANs) must realistically capture the attributes of ANs. In this paper, I develop a comprehensive modeling framework for ANs. The work I have done is concluded as the following three parts. First, I perform a comprehensive and comparative analysis of AN mobility models and evaluate the models based on several metrics: 1) networking performance, 2) ability to capture the mobility attributes of ANs, 3) randomness levels and 4) associated applications. Second, I develop two 3D mobility models and realistic boundary models. The mobility models follow physical laws behind aircraft maneuvering and therefore capture the characteristics of aircraft trajectories. Third, I suggest an estimation procedure to extract parameters in one of the models that I developed from real flight test data. The good match between the estimated trajectories and real flight trajectories also validate the suitability of the model. The mobility models and the estimation procedure lead to the creation of “realistic” simulation and evaluation environment for airborne networks.

Description: The influence of Mohandas K. Gandhi on social and environmental movements in post-colonial India has been widely acknowledged. Yet, the contributions of two European associates of Gandhi, Madeleine Slade and Catherine Mary Heilemann, better known in India as Mira Behn and Sarala Behn, have not received the due attention of the academic community. This dissertation is an examination of the philosophy and social activism of Mira Behn and Sarala Behn and their roles in the evolution of Gandhian philosophy of socioeconomic reconstruction and environmental conservation in the present Indian state of Uttarakhand. Instead of just being acolytes of Gandhi, I argue that these women developed ideas and practices that drew upon from an extensive intellectual terrain that cannot be limited to Gandhi’s work. I delineate the directions in which Gandhian thought and experiments in rural development work evolved through the lives, activism, and written contributions of these two women. Particularly, I examine their influence on social and environmental movements, such as the Chipko and the Anti-Tehri Dam movements, and their roles in promoting grassroots social development and environmental sustainability in the mountain communities of Uttarakhand. Mira Behn and Sarala Behn’s integrative philosophical worldviews present epistemological, sociopolitical, ethical, and metaphysical principles ...

Control and Automation of a Heat Shrink Tubing Process

Control and Automation of a Heat Shrink Tubing Process

Access: Use of this item is restricted to the UNT Community.
Date: August 2014
Creator: Yousefi Darani, Shahrokh
Description: Heat shrink tubing is used to insulate wire conductors, protect wires, and to create cable entry seals in wire harnessing industries. Performing this sensitive process manually is time consuming, the results are strongly dependent on the operator’s expertise, and the process presents safety concerns. Alternatively, automating the process minimizes the operators’ direct interaction, decreases the production cost over the long term, and improves quantitative and qualitative production indicators dramatically. This thesis introduces the automation of a heat shrink tubing prototype machine that benefits the wire harnessing industry. The prototype consists of an instrumented heat chamber on a linear positioning system, and is fitted with two heat guns. The chamber design allows for the directing of hot air from the heat guns onto the wire harness uniformly through radially-distributed channels. The linear positioning system is designed to move the heat chamber along the wire harness as the proper shrinkage temperature level is reached. Heat exposure time as a major factor in the heat shrink tubing process can be governed by controlling the linear speed of the heat chamber. A control unit manages the actuator position continuously by measuring the chamber’s speed and temperature. A model-based design approach is followed to design ...

Description: This study examined the correlates between the dependent variables African-American and Hispanic student enrollment in Texas public higher education to the independent variables institution type, education region, faculty demographics, curricular offerings and student organizations. Data for African-American (n = 124,000) and Hispanic enrollment (n = 314,000) in all Texas public higher education institutions (n = 109) for the 2008 academic year were examined. Significant results, using a statistical significance of p = .005, were reported for two of the variables. A correlation of Pearson's r = .946 and statistical significance of p = .000 was observed between African-American student enrollment and the percentage representation of African-American faculty in the same institution. A correlation of Pearson's r = .982 and statistical significance of p = .000 was observed between Hispanic student enrollment and the percentage representation of Hispanic faculty in the same institution. The results of this study found significant relationships between the presence of African-American and Hispanic faculty and enrollment of African-American and Hispanic students. Recommendations are made for exploring these findings in further detail.

Cosmology, Extraterrestrial Life, and the Development and Character of Western European Thought in the Seventeenth and Eighteenth Centuries

Cosmology, Extraterrestrial Life, and the Development and Character of Western European Thought in the Seventeenth and Eighteenth Centuries

Date: August 2011
Creator: Simpson, Emily
Description: Cosmology, as an all-encompassing theoretical construction of universal reality, serves as one of the best indicators for a variety of philosophical, scientific, and cultural values. Within any cosmological system, the question of extraterrestrial life is an important element. Mere existence or nonexistence, however, only exposes a small portion of the ideological significance behind the contemplation of life outside of earth. The manners by which both believers and disbelievers justify their opinions and the ways they characterize other worlds and their inhabitants show much more about the particular ideas behind such decisions and the general climate of thought surrounding those who consider the topic. By exploring both physical and abstract structures of the universe, and specifically concepts on the plurality of worlds and extraterrestrial life, Western European thought in the seventeenth and eighteenth centuries reveals not an era of pure advancement and modernization, but as a time of both tradition and change.

The Counterinsurgency Dilemma: The Causes and Consequences of State Repression of Human Rights in Civil Wars

The Counterinsurgency Dilemma: The Causes and Consequences of State Repression of Human Rights in Civil Wars

Creator: Quinn, Jason Michael
Description: In this project a theory of adaptive differential insurgency growth by the mechanism of repression driven contagion is put forth to explain variation in the membership and spatial expansion of insurgencies from 1981 to 1999. As an alternative to the dominant structural approaches in the civil war literature, Part 1 of the study proposes an interactive model of insurgency growth based on Most and Starr's opportunity and willingness framework. The findings suggest that state capacity, via its impact on state repressive behavior, plays an important gatekeeping function in selecting which minor insurgencies can grow into civil war, but contributes little to insurgency growth directly. In Part 2 of the study, I directly examine variation in insurgency membership and geographical expansion as a function of repression driven contagion. I find that repression increases the overall magnitude of insurgency activity within states, while at the same time reducing the density of insurgency activity in any one place. Despite an abundance of low intensity armed struggles against a highly diverse group of regimes around the world, I find an extremely strong and robust regularity: where repression is low - insurgencies don't grow.

Cuff-less Blood Pressure Measurement Using a Smart Phone

Cuff-less Blood Pressure Measurement Using a Smart Phone

Access: Use of this item is restricted to the UNT Community.
Date: May 2012
Creator: Jonnada, Srikanth
Description: Blood pressure is vital sign information that physicians often need as preliminary data for immediate intervention during emergency situations or for regular monitoring of people with cardiovascular diseases. Despite the availability of portable blood pressure meters in the market, they are not regularly carried by people, creating a need for an ultra-portable measurement platform or device that can be easily carried and used at all times. One such device is the smartphone which, according to comScore survey is used by 26.2% of the US adult population. the mass production of these phones with built-in sensors and high computation power has created numerous possibilities for application development in different domains including biomedical. Motivated by this capability and their extensive usage, this thesis focuses on developing a blood pressure measurement platform on smartphones. Specifically, I developed a blood pressure measurement system on a smart phone using the built-in camera and a customized external microphone. the system consists of first obtaining heart beats using the microphone and finger pulse with the camera, and finally calculating the blood pressure using the recorded data. I developed techniques for finding the best location for obtaining the data, making the system usable by all categories of people. ...

Culture and Self-Representation in the Este Court: Ercole Strozzi's Funeral Elegy of Eleonora of Aragon, a Text, Translation, and Commentary.

Access: Use of this item is restricted to the UNT Community.
Date: December 2010
Creator: Cassella, Dean Marcel
Description: This dissertation presents a previously unedited text by one of the most distinguished- yet neglected-Latin writers of the Italian Renaissance, Ercole Strozzi (1471-1508), a poet and administrator in the court of Ferrara. Under the Este Dukes, Ferrara became a major center of literary and artistic patronage. The Latin literary output of the court, however, has received insufficient scholarly scrutiny. The text is a verse funeral elegy of Eleonora of Aragon (1450-1493), the first Duchess of Ferrara. Eleonora was a remarkable woman whose talents and indefatigable efforts on behalf of her husband, her children, and her state, won her accolades both at home and abroad. She also served as a prototype for the remarkable careers of her two daughters, Isabella d'Este, and Beatrice d'Este, who are celebrated for their erudition and patronage of arts and letters. The text is a mirror of the Estense court and reveals to us how its members no doubt saw themselves, at the very peak of its temporal power and the height of its prestige as a center of cultural creativity. It is also important for the striking portrait it presents of Eleonora. Ercole Strozzi chose to call his poem an epicedium, an ancient minor literary ...
