Salome- Femme Fatale, Gaze And Rejection Of The Feminine, Ramya Thiyagarajan

Publications and Research

Salome was an unnamed, minor character in the New Testament of Mark and Matthew, an innocent girl who is presented as a pawn in her mother’s scheme to behead John the Baptist. Over time, Salome developed a life of her own, from being imagined as an acrobat in the Middle Ages, to a virgin beauty in the Renaissance and for Christians a constant example of evil woman. In 1891, Salome was reborn as the erotic femme fatale through the imagination of Oscar Wilde and given an existence on the stage, though the play was banned for years. Only after an …

Development Of Dc Circuit Breakers For Medium-Voltage Electrified Transportation, Trevor Morgan Arvin

Theses and Dissertations--Electrical and Computer Engineering

Medium-voltage DC (MVDC) distribution is an enabling technology for the electrification of transportation such as aircraft and shipboard. One main obstacle for DC distribution is the lack of adequate circuit fault protection. The challenges are due to the rapidly rising fault currents and absence of zero crossings in DC systems compared to AC counterparts. Existing DC breaker solutions lack comprehensive consideration of energy efficiency, power density, fault interruption speed, reliability, and implementation cost.

In this thesis, two circuit topologies of improved DC circuit breakers are developed: the resonant current source based hybrid DC breaker (RCS-HDCB) and the high temperature superconductor …

Models And Optimal Controls For Smart Homes And Their Integration Into The Electric Power Grid, Huangjie Gong

Theses and Dissertations--Electrical and Computer Engineering

Smart homes can operate as a distributed energy resource (DER), when equipped with controllable high-efficiency appliances, solar photovoltaic (PV) generators, electric vehicles (EV) and energy storage systems (ESS). The high penetration of such buildings changes the typical electric power load profile, which without appropriate controls, may become a “duck curve” when the surplus PV generation is high, or a “dragon curve” when the EV charging load is high. A smart home may contribute to an optimal solution of such problems through the energy storage capacity, provided by its by battery energy storage system (BESS), heating, ventilation, and air conditioning (HVAC) …

Synthesizing Dysarthric Speech Using Multi-Speaker Tts For Dsyarthric Speech Recognition, Mohammad Soleymanpour

Theses and Dissertations--Electrical and Computer Engineering

Dysarthria is a motor speech disorder often characterized by reduced speech intelligibility through slow, uncoordinated control of speech production muscles. Automatic Speech recognition (ASR) systems may help dysarthric talkers communicate more effectively. However, robust dysarthria-specific ASR requires a significant amount of training speech is required, which is not readily available for dysarthric talkers.

In this dissertation, we investigate dysarthric speech augmentation and synthesis methods. To better understand differences in prosodic and acoustic characteristics of dysarthric spontaneous speech at varying severity levels, a comparative study between typical and dysarthric speech was conducted. These characteristics are important components for dysarthric speech modeling, …

Parametric Average-Value Modeling, Simulation, And Characterization Of Machine-Rectifier Systems, Isuje Ojo

Theses and Dissertations--Electrical and Computer Engineering

There are many techniques for modeling and simulation of synchronous machine-rectifier systems. The more common approaches are the detailed and average-value modeling techniques. The detailed simulation technique takes into account the details of the diode switching and is both very accurate and very expensive in terms of computational resources. To alleviate this disadvantage, the average-value modeling technique is often utilized. In this approach, the details of diode switching are neglected or averaged. In that light, the work presented herein proposes a unique saliency-sensitive parametric average-value model (SSPAVM) of the synchronous machine-rectifier system. This model extends existing parametric average-value models to …

Land Is Life: Settler Colonial Governance Of National Parks And Hunting In Taiwan, Wei-Chieh Jarita Chen

Environmental Studies Honors Projects

This thesis situates Taiwan as a settler colonial state by examining the discourse around the governance of national parks and the criminalization of Indigenous hunting. Placed in the context of historical patterns of land dispossession and cultural genocide, these two issues represent the ongoing process of settler colonialism and the reproduction of settler colonial relations through environmentalism. I focus on the narratives around three case studies: the controversial and ultimately unsuccessful campaign for the Maqaw National Park, the Tumpu Daingaz buluo’s struggle with the Yushan National Park, and the Tama Talum Indigenous hunting constitutional reinterpretation case. I argue that settler …

The Role Of Son In Chromatin-Mediated Gene Expression, Melissa Jordan Ward

Browse all Theses and Dissertations

Gene expression in mammalian cells requires complex nuclear choreography, and there is increasing evidence that spatiotemporal organization of chromatin and nuclear compartments plays an important role in gene expression. In this dissertation, I examined the function of SON, a splicing factor with a known role in nuclear organization, in chromatin-mediated gene expression. SON association with a transcriptionally inactive U2OS 2-6-3 reporter gene array provided a useful model to study SON’s chromatin dynamics. I demonstrated that SON associates with the inactive but not the activated array, and that SON’s RNA binding domains are not necessary for that association. Second, I discovered …

Mixed-Effects Regression Models For Analyzing Data With Excess Zeros, Guangyu Xu

Browse all Theses and Dissertations

Data with excess zeros are common in many applications. Failure to account for the extra zeros may lead to biased estimates and misleading inference when analyzing this data type. To investigate the association between a set of predictor variables and an outcome variable with excess zeros, two kinds of regression models, the hurdle model and the zero-inflated model, are commonly used. In these models, the traditional tests, such as the likelihood-ratio test and the Wald test, can only be used to detect the fixed effects in association analysis. Recently, several random-effects or mixed-effects tests have been proposed for association analysis, …
