The Self Haunting the Self: Assimilation, Imperialism, and the Fragmented Self in Asian-American Gothic
Get PDFIn this thesis, I employ Lisa Lowe’s theory of Asian-American identity formation to claim that in Asian-American gothic, one of the conflicting fragments of the Asian-American self is externalized in a ghost/monster/villain. This version of the self haunts another version of the self, which reveals that in the Asian-American subject, the Asian self grounded in Asian/Asian-American culture and history is in tension with the Americanized self influenced by the forces of assimilation and U.S. imperialism to forget Asian/Asian-American culture and history. The self haunting the self prompts the Americanized self to remember the histories of imperialism in Asia and marginalization in the U.S., which undermines the obligation to forget enforced by assimilation and imperialism. However, the inner turmoil afflicting the Asian-American subject is never completely assuaged because forces of assimilation and marginalization continue to act on the self, and by resisting reconciliation with the Americanized self, the Asian-American self resists assimilation to the dominant American identity. The ghostly self cannot be exorcised, only re-internalized by the self. Therefore, the self and self are caught in a perpetual haunting, epitomizing the lack of resolution for the fragmented Asian-American identity. </p

A Comprehensive Approach to Aircraft Wind Measurement: Instrument Calibration and Sensor Fusion for Uncertainty Bounded Wind Estimation
Get PDFEstablishing uncertainty bounds is critical for quantifying the quality and reliability of multi-hole probe (MHP) wind measurements in field campaigns. Accurate wind estimation is vital for atmospheric research, and incorporating uncertainty quantification into quality control (QC) protocols provides a context for measurements. Uncertainty bounds reveal limitations of measurements and improve the scientific value of field campaign data sets.
Accurate measurement begins with accurate instrument calibration. To address limitations in conventional calibration methods, a CFD-assisted audit for standard multi-hole probe (MHP) calibration was developed. This approach quantifies wind tunnel blockage effects and in-flight airframe-induced flow distortions, leading to improved calibration coefficient derivation. The calibration process reduces median vertical wind estimate errors by-0.47 m/s and horizontal wind speed and direction errors by 0.05 m/s and-0.17◦, respectively. These improvements were observed during flights with average horizontal and vertical wind speeds of 12 m/s and 0 m/s.
Building on these calibration improvements, an uncertainty quantification framework was implemented to provide 95% confidence bounds for wind vector estimates. Analysis of field data from the Tracking Aerosol Convection Interactions Experiment (TRACER) yielded MHP-derived wind speed uncertainties with horizontal wind uncertainties averaging 0.78 m/s for speed and 1.1◦ for direction, and vertical wind uncertainty averaging 0.26 m/s, for flights where mean horizontal and vertical wind speeds of 5 m/s and of 0.25 m/s. These results highlight the robustness of the uncertainty estimation framework in real-world conditions.
Simulations were conducted to evaluate the impact of sensor fusion on wind estimation accuracy. The application of the Sequential Importance Resampling (SIR) Particle Filter with all available sensor measurements yielded optimal accuracy and uncertainty, achieving mean errors of 0.13 m/s, 0.14 m/s, and 0.06 m/s for the body-frame uw, vw, and ww wind components, for a wind field with an oscillating body-frame uw wind with an amplitude of 5 m/s, and 0 m/s body-frame vw and ww winds. Experimental flight data further validated these findings, with achieved uncertainties of 0.16 m/s, 0.16 m/s, and 0.15 m/s for the corresponding wind components for conditions with mean horizontal and vertical wind speeds of 1.7 m/s and -0.25 m/s . The total horizontal wind uncertainty averaged ±0.23 m/s, demonstrating improved certainty compared to conventional wind measurement systems.
Additionally, this study demonstrated that accurate vertical wind estimation is possible even in the absence of external airflow measurements. The omission of MHP data resulted in only a minor increase in vertical wind uncertainty, averaging 0.05 m/s for orbit and racetrack flight patterns while maintaining overall accuracy. These findings indicate that sufficient sensor redundancy can compensate for missing measurements in specific flight conditions.
The insights gained from this research provide a comprehensive foundation for future efforts to enhance wind measurement performance and extend the proposed methodologies to other sUAS platforms. This work contributes to advancing atmospheric science applications by improving the accuracy, reliability, and certainty of wind estimation using sUAS. Elements of this research have been incorporated into data processing workflows for field campaigns, providing uncertainty characterization in real-world atmospheric observations.</p
Improved Control of Superconducting Qubits With Static and Parametric Couplings
Get PDFThis thesis explores novel strategies for advancing superconducting quantum computing through a series of experimental investigations and device innovations. Grounded in the development of circuit quantum electrodynamics, the work addresses the challenges posed by the limitations of coherent control, coherence time and scaling of superconducting qubits. Focusing on transmon qubits, the thesis first reviews the foundational principles of circuit quantum electrodynamics and the critical role of the transmon in achieving robust qubit performance.
Three experimental studies form the core of this work. The first study demonstrates a universal quantum gate set for strongly coupled transmons. By exploiting the residual ZZ interaction, the work introduces a novel two-axis gate protocol for single-qubit operations and implements both CZ and CNOT gates with high fidelities, highlighting the potential for fast, low-error quantum operations in the strong coupling regime. The second study investigates a dual-rail qubit architecture using parametrically coupled transmons, showcasing a hardware-efficient approach to quantum error correction. This experiment converts single-photon loss errors into detectable erasures and leverages mid-circuit detection to enhance qubit coherence, thereby advancing fault-tolerant quantum computing schemes in the NISQ era. The final study focuses on the development of merged-element transmons (MET) and their FinMET variants. By integrating the Josephson junction and shunt capacitor into a single trilayer device, these innovations achieve a dramatic reduction in device footprint while addressing loss channels through advanced materials engineering, ultimately paving the way for scalable, high-coherence quantum circuits.
Collectively, these contributions demonstrate significant progress in quantum gate design, error mitigation, and qubit architecture, offering promising routes toward the realization of largescale, fault-tolerant quantum computers</p
Depth and Bathymetry of Supraglacial Melt Ponds from Remote Sensing Observations
Get PDFThere are many proposed methods for remotely sensing supraglacial meltwater depth. Methods using multispectral imagery calculate depth based on the reflectance of water pixels, however while many of these methods have been shown to work well for depth, they do not provide bathymetry. The most reliable method to calculate both depth and bathymetry uses ICESat-2 photon returns from the air-water and water-ice interfaces. However, ICESat-2 is limited by its narrow beam width and 91-day repeat cycle. Here, I propose a novel method for extracting both depth and bathymetry from paired WorldView imagery and corresponding digital elevation models (DEMs), whereby the optical depth is subtracted from the DEM water surface to calculate bathymetry. Focusing on Petermann Glacier, Greenland, I show that this method can be used to augment the spatial coverage and temporal resolution of ICESat-2 for calculating supraglacial water depth and basin bathymetry. I find that a physically based dual-channel model using the blue and green bands, paired with the corresponding DEM, provides the most accurate depth and bathymetry estimates (RMSE = 0.54 m) when validated with ICESat-2 data. This novel method has the potential to vastly improve our ability to monitor supraglacial hydrology and meltwater storage, which could in turn inform us about ice shelf stability in Greenland and Antarctica as the climate continues to warm.</p
Irregular Tonal Patterns Beyond Standard Mandarin Correspondences in the Fuyang Dialect
Get PDFThis thesis investigates tonal irregularities in the Fuyang dialect. While Fuyang (FY) shares core grammatical and lexical features with Standard Mandarin (SM), its distinct tonal system remains understudied. A commonly cited SM-to-FY tonal conversion pattern - SM tone 1 to FY tone 3, tone 2 to tone 1, tone 3 to tone 2, and tone 4 to tone 4 - helps explain broad tone shifts. However, native FY speakers frequently produce tones that deviate from these expectations, raising questions about the consistency and underlying logic of these “irregular” realizations.
This study draws on over 160 minutes of natural conversational speech from eleven native FY speakers across four age groups. 410 instances of irregular tonal realization across 105 unique characters were identified and analyzed. The findings reveal both speaker-specific and item-specific patterns. FY tone 3 was disproportionately frequent as an irregular output, while FY tone 4 was notably avoided. Speaker background, particularly exposure to SM, correlated with the rate of irregular character usage, though not with retention of SM tones. Case studies of individual characters (e.g., 不, 一, 只) suggest that FY possesses internal tone sandhi patterns that are independent from SM sandhi processes.
These results contribute to our understanding of tonal variation in Fuyang and underscores the value of documenting underrepresented dialects to preserve linguistic diversity.</p
