Disparities In The Identification Of Vulnerable Communities Due To Design Storm Methods: A Case Study In The Vermilion River Watershed, South Louisiana, Usa, Claire Orgeron

Masters Theses

Accurately identifying socially vulnerable populations at-risk of flooding is critical for equitable disaster mitigation and planning. This study investigates how the selection of design storm method, which is fundamental to developing flood risk maps used for this identification, influences which socially vulnerable populations are recognized as being at elevated flood risk. The most widely used design storm approach relies on National Oceanic and Atmospheric Administration (NOAA) Atlas 14 point-based rainfall frequency estimates. These estimates are typically applied spatially using areal reduction factors, thereby disregarding rainfall spatial variability in real storms. Stochastic Storm Transposition (SST), an alternative design storm approach that …

Lower Extremity Muscle Activation In Elite Female Field Hockey Players With And Without Low Back Pain During A Prone Hip Extension, Madison S. Cornell

Masters Theses

Context: Low back pain (LBP) is a common chronic injury seen in field hockey players and more prominent in females than males. The purpose of this study was to identify if bilateral muscle activation differences exist in erector spinae (ES), gluteus maximus (Gmax), and biceps femoris (BF) in collegiate female field hockey players with and without LBP during a prone hip extension (PHE). It was hypothesized that individuals in the LBP group would have decreased Gmax and increased BF activation. Methods: A cohort design was utilized through a convenience sample to analyze variations in the dependent variables (muscle activation, flexibility, …

Adaptive Position Sensor Harmonic Compensation In Pmsm Drives, Gayan Dissanayake

Masters Theses

Permanent Magnet Synchronous Machines (PMSMs) have emerged as a preferred class of electromechanical energy converters due to their high efficiency, high torque density, and other inherent advantages. Accurate rotor position information is essential for proper commutation and effective field-oriented control (FOC), making precise position sensing critically important. In practice, however, harmonic errors introduced by the position sensing subsystem can lead to undesirable torque ripple and degraded performance. Most existing approaches for mitigating these errors are passive in nature and lack the capability to actively adapt to harmonic variations under changing operating conditions. Since the harmonic content in the position can …

Gis-Based Solar Energy Suitability Assessment For Utility-Scale Photovoltaic Development In Texas, Deepak Kumar

Masters Theses

Real Time Grid Connected Der Inverter Control Fault Ride Through Model In Accordance With Ieee 1547–2018 Standard, Mark Joseph Booge

Masters Theses

Distributed Energy Resources (DERs) include inverter-based power generation units, which are increasing in demand due to the rising consumption of energy, need for improved grid stability, and other environmental factors. DERs can either supply or supplement the grid using different control strategies depending on the grid’s needs. IEEE standard 1547-2018 dictates the interconnection and operation requirements of grid-connected DERs under nominal and abnormal voltage conditions. Although inverter ride-through operation has been widely studied, the effects of the standard’s time-based requirements within a distribution grid system require further investigation.

This study investigates how the IEEE 1547-2018 time-based ride-through requirements affect a …

Understanding The Effect Of Scaling On Aerodynamic Force Analysis Of The Nrel Phase Vi Wind Turbine, Patrick R. West

Masters Theses

It is challenging for small models and prototypes to accurately reflect the aerodynamic performance of a full-scale wind turbine, especially for offshore turbines. It is also not economical to build full-scale models for prototype testing. Scaling makes it possible to modify the dimensions for computational simulations, simplify the prototype construction and testing process, and make aerodynamic load analysis applicable to larger blade diameters. In this work, a model is presented that considers the effects of geometric scaling by modifying the incoming windspeeds and rotational speed of the turbine rotor in capturing aerodynamic load through Computational Fluid Dynamics. The National Renewable …

Distilled Intelligence At The Edge: An Iot-Driven Deep Learning Architecture For Plant Health Assessment, Malek Garrach

Masters Theses

This project addresses the challenge of image classification for specific plants in indoor farming environments. With a limited dataset, selecting an efficient and cost-effective model becomes crucial.

The traditional approach of using cloud services for model storage and image processing is not only expensive but also inefficient for this use case, especially when considering the continuous flow of data generated by cameras in indoor farming settings. Cloud-based solutions incur high operational costs, which is not ideal for resource-constrained environments. To overcome these limitations and provide a more economical alternative, we propose the use of IoT devices, specifically Raspberry Pi units, …

Results did not support the …

The Relation Between Parental Bonding And Sexual Self-Concept In College Students, Kinsey Hatfield

Masters Theses

This thesis explores the relation between two dimensions of parental bonding—care and overprotection—and four aspects of sexual self-concept including sexual agency, desire, anxiety, and satisfaction in college students. We also explored the use of a relatively novel measure of sexual self-concept, the MSSCQ-SF. 292 college students completed measures regarding parental bonding, sexual self-concept, and various demographic questions. Results partially supported our hypotheses, with parental care and overprotection being correlated with sexual anxiety and satisfaction but not desire or agency. Further, parental overprotection was positively correlated with sexual anxiety above and beyond the demographic variables assessed. These findings suggest that parental …

Wake-On-Anomaly Federated Architecture For Privacy-Preserving Poultry Health Early Warning, Mahmoud Aziz Louati

Masters Theses

Highly pathogenic avian influenza outbreaks, respiratory disease, heat stress, and silent equipment failures share one operational reality: they are detected too late because today’s poultry-health workflow is reactive, manual, and dependent on producers volunteering commercially sensitive data. This thesis presents a wake-on-anomaly federated architecture that addresses both the detection-latency problem and the privacy–adoption deadlock that has so far prevented cross-farm collaboration. The architecture is organized in two tiers. Tier 1 is a lightweight LSTM autoencoder that continuously screens four routine telemetry channels (water, feed, house temperature, activity proxy) and emits a per-window reconstruction-error score. A debounced k-of-m trigger with cooldown …

Kev's Dinghy Boat Workshops, Ruiyang Xiao

Masters Theses

In a culture where convenience replaces process, this project argues that making — even when inefficient, imperfect, or unnecessary — enables forms of engagement that buying cannot.

Technologies and Services nowadays are able to fulfill human’s desire to travel and explore at ease. However, this convenience proposes a mode of engagement based only in deeper knowledge of context and thus our experience with the world around us is hence diminished. Our engagement with the world becomes heavily mediated, regulated and controlled.

This project investigates how hands-on engagement with water can reintroduce + restore our sense of joy, curiosity, consequence, and …

Forgotten Threads: The Embodiment Of Time And Memory In Jewelry., Alees Yang

Masters Theses

Memory rarely returns whole. More often, it persists through fragments, sensations, and traces carried by the body. This thesis explores how jewelry can materialize the unstable relationship between memory, forgetting, and bodily experience. Drawing from personal experiences of family, migration, and loss—particularly witnessing my grandfather’s gradual memory deterioration through Alzheimer’s disease—I reconsider forgetting not as absence, but as a condition through which emotional traces continue to persist.

Through fabric, fragmented photographs, and processes of fraying and dispersal, my work examines how memories are continuously reconstructed. Influenced by the Chinese aesthetic concept of liubai (negative space) — I investigate how incompleteness …

A Pot Of Gold At The End Of The Assembly Line: Jewelry, Facture, And Alienation, Jonathon A. Zalakos

Masters Theses

A Pot of Gold at the End of the Assembly Line integrates icons of mass-manufacturing with signifiers of joyful work, stimulating a dialogue between industrial and craft labour. Visible traces of the making process left on these works conjure a spectral ‘maker’, implied by the fingerprints, toolmarks, assembly, and conspicuous decision making of an ‘other’. As we relate to these signifiers as opportunities for our own bodily action, this spectre speaks in our own voice. Possessed by this ghost, viewers are vicariously thrust into an imaginary context and made sensitive to the nature of this work — whether it validates …

Kicau Kericau: The Chirps And Warbles Of A Bird-Human Story, Airien Ludin

Masters Theses

This thesis tells the tale of bird-human relationships and what it means to live alongside one another, subverting the hierarchical view of humans as above birds inherited from colonial history. It asks how the practice of illustration can function as a site of Two-Eyed Seeing, where scientific and local knowledge are held together as an entangled narrative. It also examines how mendongeng (storytelling), as I have experienced it within Indonesian culture and everyday contexts, can help us understand birds as a companion species with their own agency.

This project takes two forms: first, a picture book titled Sun Bird …

Tùn-Scene And A-Futurism: Biomythography, Opacity, And Posthuman Imagination, Minglu Du

Masters Theses

Grounded in the author’s position as a Chinese feminist, this thesis examines how East Asian women, as well as East Asian-coded femininity more broadly, are objectified and othered within futurist visual culture in the age of artificial intelligence. Through an engagement with ornamentalism, techno-Orientalism, and posthumanism1 , it argues that the persistent figure of the feminized humanoid cyborg continues to reproduce colonial and patriarchal structures of desire, rendering marginalized bodies as fetishized and violable surfaces. In response, the thesis develops Tùn-Scene, a biomythographic artistic framework and the first experiment in what the author provisionally names A-Futurism. Drawing on Donna Haraway’s …

I Miss My Computer: Online Artistry, Web Aesthetics, And Coming-Of-Age In A Digital Landscape, Catherine Capeci

Masters Theses

This thesis explores how young artists develop their creative practices in a world informed by digitality. Through survey research of 44 art students between the ages of 14 and 22, as well as a process of autoethnographic inquiry, I examine how artists in high school and college relate to digital imagery, web archives, online gaming, and social media platforms, and how these experiences inform artmaking. I believe that art educators should explore how the internet informs aesthetic and conceptual sensibilities, and how these sensibilities show up in young artists’ work, more so than focus on digital media as its own …

To accomplish this goal, I attended seven art museums within the region of New England at which I participated in …

"Hand And Mind Lead To Life": Craft Pedagogy In Art Education For Older Adolescent Learners, Katherine Fu

Masters Theses

Art educator Jo-Anna Moore (1991) asks “What is the purpose of our individual growth through art or craft?” (p. 162). Moore’s question is daunting not least for the seasoned artist, but for the young people in our art classrooms who, to varying degrees, are or are not interested in art. This thesis draws from my personal narrative as an older adolescent whose introduction to craft helped me navigate great questions of identity, belonging, and motivation. It seeks to discover how craft can become a method of teaching art to all students, and in particular, how such a pedagogy addresses the …

Where My Memory Settles, Rachel Kobb

Masters Theses

My memory is blurry but ever present in an atmospheric state. Through my investigations of memory and sensorial experience, this thesis is an attempt to understand how the body recalls the spaces I have spent the most time: my various homes through life.

The output of this thesis is a paper installation that layers and translates spatial qualities of my past homes. The home is not a neutral container, but instead a space that should support a sense of retreat and security. Drawing upon Gaston Bachelard’s zones of experience, I explore how a domestic space is moved through distinct zones. …

Between Nature And Architecture : A Dialogue Of Five Elements, Niexiangyi He

Masters Theses

Rooted in classical Chinese cosmology, the Daoist Five Elements (Wood, Fire, Earth, Metal, and Water) describe dynamic cycles of mutual generation (sheng)—in which one element produces or supports another—and restraint (ke)—in which elements regulate or limit one another to maintain balance. Rather than a system of symbolic representation, these interactions outline a relational model of equilibrium based on interdependence and continuous transformation. Wood, Fire, Earth, Metal, and Water can inform a contemporary design framework for interior and architectural practice. It interprets these cycles as a form of spatial logic that guides material selection, structural organization, environmental modulation, and experiential sequencing, …

Soft Bodies, Hard Frames, Emily Zhang

Masters Theses

Silk is delicate yet strong, responsive to light and air, dependent on living processes and careful labor. These qualities position silk not only as a material object, but as an instrument capable of organizing space. Rather than functioning solely as a surface or decorative textile, silk can operate as a spatial generator, shaping enclosure, movement, and environmental conditions.

For centuries, domestic courtyard houses in the Jiangnan region, located south of the Yangtze River, evolved alongside sericulture, forming spaces that were attuned to the environmental and material requirements of silk. Architectural elements such as courtyards, screened openings, flexible interiors, and canal-directed …

Soft Space/Strong Support, Keqian Li

Masters Theses

Children with early developmental challenges such as anxiety disorders, ADHD, autism, and sensory regulation difficulties often navigate environments that are not designed to support their emotional, cognitive, and sensory needs. In many educational and community spaces, inclusion is treated as an add-on or a specialized accommodation rather than as a fundamental design principle.

This thesis argues that inclusion should be the standard, not the exception, and that interior architecture can function as an early intervention tool that actively supports children’s development. This project examines how spatial design can influence emotional regulation and social interaction for children with early developmental challenges. …
