Declarative Design For Spatial Analysis Models, Yassine Elouri Jan 2025

Declarative Design For Spatial Analysis Models, Yassine Elouri

CGU Theses & Dissertations

Geographic Information Systems (GIS) have become indispensable tools in addressing complex spatial challenges across diverse domains, including urban planning, environmental conservation, and climate change. However, the technical expertise required to use GIS effectively, particularly proficiency in general-purpose programming languages (GPLs), remains a significant barrier to broader adoption. Domain-Specific Languages (DSLs) have proven to lower this barrier by offering tailored abstractions that simplify problem-solving in specific domains. Despite their potential, the GIS domain lacks a formal DSL framework that bridges the gap between the design of spatial analysis models and their practical implementation. This research addresses this gap by proposing Gaia, …

Coupling Remote Sensing And Modelling To Monitor The Spatial Distribution And Trends Of Surface Temperature And Ice Thickness On Sub-Arctic Lakes, Gifty Attiah

Theses and Dissertations (Comprehensive)

Lake surface temperature (LST), lake ice thickness (LIT), and lake ice phenology (LIP) play significant roles in the diverse regional processes of freshwater in cold regions. They offer direct indications of regional weather and climate conditions, and their interactions with the atmosphere impact climate processes. Furthermore, lake ice is valuable to northern communities, such as those in the Northwest Territories (NWT). Ice roads, including the longest ice road in the NWT, spanning over 80 lakes, are constructed during winter to haul goods to and from industrial establishments (e.g., mines) and for travel within and between communities. A significant challenge to …

Applying Transfer Learning For Street-Scale Nuisance Flood Forecasting In Coastal-Urban Cities, Binata Roy, Jonathan L. Goodall, Diana Mcspadden, Chetan Kumar, Steven Goldenberg, Yidi Wang, Malachi Schram

VMASC Publications

An important challenge with Machine Learning (ML) is its transferability; i.e., whether a ML model trained on one set of data can be applied to a second set of data without requiring full re-training of the model. Transfer Learning (TL) addresses this challenge by transferring knowledge learned in the source domain (the data it was trained on) to the target domain (a second set of data that is statistically different but related, which the model was not trained on). This study investigates the use of TL for street-scale nuisance flood forecasting by exploring whether a ML model trained for one …

Atmospheric Chemistry Experiment (Ace) Winds, Matthew Wyatt, Peter F. Bernath, Chris Boone, Léo Lavy, Ryan Johnson

Chemistry & Biochemistry Faculty Publications

The Atmospheric Chemistry Experiment Fourier Transform Spectrometer (ACE-FTS) uses limb geometry to measure transmittance spectra of Earth's atmosphere by solar occultation. Line-of-sight wind speeds can be derived via Doppler shifts of molecular lines in infrared spectra. The wind look direction angles relative to geodetic North are derived from geometry. We validate the new ACE version 5.3 (v.5.3) line-of-sight winds with MIGHTI and meteor radar vector wind observations and find a ±15 m/s sunrise/sunset shift above 80 km. We also compare line-of-sight winds from ACE-FTS v.5.2 and v.5.3 with vector winds from the MERRA-2, HWM14, and WACCM-X models. A ±15 m/s …

The New Urbanism In New York City: A Case Study Comparing Battery Park City And Alphabet City, Lena Farley Jan 2025

The New Urbanism In New York City: A Case Study Comparing Battery Park City And Alphabet City, Lena Farley

Pomona Senior Theses

This thesis examines two Manhattan neighborhoods, Battery Park City and Alphabet City, through the lens of New Urbanism—an urban planning approach developed in the 1990s. New Urbanist principles prioritize walkability, connectivity, mixed-use development, diversity, varied housing options, architectural quality, green transportation, sustainability, and accessible green spaces. While Battery Park City represents a top-down, master-planned New Urbanist neighborhood based on a 1979 plan, Alphabet City emerged from the 1811 Manhattan grid with significant community-driven design, notably through community gardens and grassroots initiatives. Using a mixed-methods approach including residential surveys, qualitative, and quantitative analyses, this research investigates how these neighborhoods embody New …

Plastic Gerontologies: Epigenetic Clocks As Instruments Of The Profitable Medicalization Of Aging, Hans T. Purisch Jan 2025

Plastic Gerontologies: Epigenetic Clocks As Instruments Of The Profitable Medicalization Of Aging, Hans T. Purisch

Theses and Dissertations--Geography

Epigenetic clocks are algorithms that use epigenetic biomarkers of aging to calculate an organism’s ‘biological age.’ Through discursive analysis of commercially available epigenetic clock marketing materials, scientific articles, and interviews with actors in the longevity biotechnology industry, this study examines the commercialization of epigenetic clocks in the form of consumer test-kits. The study argues that longevity biotechnology companies leverage the malleable and fluid qualities of epigenetic markers of biological age to extend the domains of profitable therapies. It shows that epigenetic clock companies market the dynamic qualities of epigenetic biological age measurements to redefine health around the project of optimizing …

Land Rematriation: Utilizing The National Register Of Historic Places And Developing Tribal Homeland Territories For The Restoration Of Historic Landscapes And Sovereignty, Robert E. Hazen Jan 2025

Land Rematriation: Utilizing The National Register Of Historic Places And Developing Tribal Homeland Territories For The Restoration Of Historic Landscapes And Sovereignty, Robert E. Hazen

Dissertations, Master's Theses and Master's Reports

Land rematriation and cultural revitalization are crucial to addressing the ongoing impacts of settler colonialism on Indigenous communities, particularly for the Lac Vieux Desert Band of Lake Superior Chippewa. The National Register of Historic Places and federal recognition processes have traditionally marginalized Indigenous practices and land claims, yet, as I argue in this thesis, they hold potential for reappropriation in support of sovereignty and heritage. This thesis argues that integrating Indigenous methodologies, geospatial research, and archival analyses can forge a path toward effective land rematriation efforts. My findings reveal culturally significant sites connected to the historic village of Getegitigaaning, helping …

Impacts Of Southern Pine Beetle (Dendroctonus Frontalis Zimmerman) On Loblolly Pine (Pinus Taeda L.) Canopy And Water Use In The Homochitto National Forest, Mississippi, Usa, Sasha Goodnow, Yun Yang, Hui Liu, Ashley Schulz

Endeavors: Mississippi State Undergraduate Research Journal

Abiotic and biotic forest disturbances can have many impacts to forest ecosystem services, including to forest water use. Studies on impacts to forest evapotranspiration have been conducted on the mountain pine beetle (Dendroctonus ponderosae) in western North America, but not on the southern pine beetle (Dendroctonus frontalis), which is a native pest of loblolly pine (Pinus taeda) and shortleaf pine (Pinus echinata), in the southeastern United States. Stressed pine trees produce pheromones that attract southern pine beetles and, with enough stressed trees, beetle populations can quickly grow to epidemic levels and attack healthy trees, which results in widespread tree mortality. …
