Automated Classification, Measurement, And Semantic Segmentation Of Open-Web Joists From Point Cloud Data, Justin Raymond Dworacek

Theses and Dissertations

This thesis presents a BIM-oriented methodology for the automated classification, measurement, and segmentation of structural trusses from point cloud data. A real truss point cloud and a complementary synthetic dataset derived from CADBIM Revit families were used to develop and evaluate the workflow. Classification was performed using a rule-based Python algorithm based on principal component analysis, side-view feature extraction, and family-specific geometric decision logic, while a separate family-aware script was used to extract key truss dimensions. Semantic segmentation was evaluated using a PointTransformerV3 model to separate truss and non-truss points in mixed point cloud scenes. The results demonstrated strong performance …

Mountain Development In Nepal: Settlements, Infrastructure, And Economic Transformation, Keshav Bhattarai, Ambika P. Adhikari

Himalayan Research Papers Archive

As Nepal urbanizes, expands infrastructure, strengthens local governments, and explores deeper connectivity with India and China, climate change is increasing floods, landslides, heat, and water insecurity. Rapid internal migration, rising disaster risks, youth outmigration, and dependence on remittances are also revealing the limits of conventional urban development, especially in the mountainous region. The central challenge for Nepal is no longer just to accommodate growing towns and cities, but to build settlements that are safe, productive, environmentally resilient, and capable of sustaining long-term prosperity.

This paper argues that Nepal's urban future must be guided by a new development paradigm centered on …

Spatiotemporal Assessment Of Coastal Urban Heat In Buenos Aires Using Satellite Landsat Lst, Noah Morales, Lleyton Naar, Dan Macchiarella, Kevin Adkins, Ronny Schroeder

Student Works

Coastal urban environments exhibit complex surface temperature patterns driven by interactions among water, vegetation, and built infrastructure. This study investigates land surface temperature (LST) variability along a coastal-to-urban transect in Parque de los Niños, Buenos Aires, by integrating multi-year satellite Landsat LST with high-resolution thermal data collected from an uncrewed aircraft system (UAS). Landsat provides the temporal depth necessary to assess seasonal and interannual variability in surface temperature, including responses to extreme summer conditions. However, their spatial resolution limits the ability to resolve fine-scale thermal gradients near shoreline boundaries and within heterogeneous urban landscapes. UAS thermal observations address this limitation …

A Novel Edge-Based Accuracy Assessment Framework For Target Detection From Remotely Sensed Images, Yingfan Zhang, Weiyi Hou, Lyndon Estes, Rui Lu, Shijie Zhu, Aiyin Zhang, Zhou Shi, Su Ye

Geography

Accuracy assessment is critical for evaluating map quality and improving algorithms for target detection in remotely sensed images. Traditional methods for assessing a target-detection task were often performed by estimating the relative pixels of correct and incorrect identifications (e.g., F1 score). However, this approach only considers the pixel-by-pixel agreement and ignores important aspects of positional errors and target object quality. To provide comprehensive diagnostic information, we propose a novel edge-based accuracy assessment framework. This framework firstly applied a newly proposed assessment tool, Dynamic Epsilon-band Accuracy Function (DEAF), which is a linear fitting function from a series of edge accuracies associated …

Geography

Hawaiʻi’s complex topography, pronounced microclimates, and geographic isolation make coarse-scale global climate model output inadequate for local planning, and high-resolution climate projections tailored to the state have until now been lacking. To address this gap, we introduce the NASA Earth eXchange Hawaiʻi Downscaled Climate Projections CMIP6 (NEX-HIDCP-CMIP6), a new archive of downscaled historical and future climate projections based on output from Phase 6 of the Coupled Model Intercomparison Project (CMIP6) over the State of Hawaiʻi. The dataset covers the years 1950–2100 and includes three variables (maximum temperature, minimum temperature, and precipitation) from five CMIP6 experiments (the historical experiment and the …

Using A Social-Ecological-Technological Systems Approach For Assessing Vulnerabilities Downstream Of Dams, Michael J. Englert

All Graduate Reports and Creative Projects, Fall 2023 to Present

Dam failure is rare, but when it occurs the consequences can extend far beyond the structure of the dam itself. This project assessed vulnerabilities downstream of Utah’s 189 state-regulated, high-hazard dams using a Social-Ecological-Technological Systems (SETS) approach. The purpose of the project was to look beyond engineering and structural risk alone and identify the people, protected ecosystems, critical infrastructure, and land cover types located within mapped dam inundation zones.

Potential inundation zone maps were obtained from the Utah Division of Water Rights Dam Safety Section. They were processed using ArcGIS Pro and integrated with publicly available nationwide geospatial datasets to …

Casual Killing In The Home: Ecological Citizenship And The Micro-Geopolitics Of Mosquito Cohabitation, Orlando Woods, Junxi Qian

Research Collection College of Integrative Studies

This article explores how the visceral acts of being bitten by and killing mosquitoes can underpin the formation of ecological citizenship. This form of citizenship is premised on human-nature entanglement and raises questions concerning how the rights and responsibilities stemming from such entanglement become distributed across the public and private domains. As a space in which mosquito cohabitation is contested daily, the home is a key site through which ecological citizenship can be forged and theoretical debates concerning urban political ecology can be extended. Human-mosquito entanglements in the home can reveal the limits of public pest management strategies, the partiality …

This integration of all three frameworks into one locally …

Situs Lida Ajer Dalam Konteks Supererupsi Erupsi Toba, Zulianikha S. Putri, Arni Nazirawati, Alia Fatima

Multikultura

The Toba eruption approximately 74,000 years ago was one of the largest volcanic events of the Quaternary and is often associated with the catastrophic hypothesis, which argues that the event caused extreme global cooling and severe reductions in human populations. However, recent studies suggest that its impacts were less destructive than previously assumed. This paper examines the position of Lida Ajer Cave within the context of the Toba eruption through a literature review of archaeological, geological, and paleoenvironmental publications. The review shows that the presence of Homo sapiens at Lida Ajer, dated to approximately 73,000–63,000 years ago, places the site …

Cramer’S V-Based Driver Screening For Land-Use Change Prediction In A Flood-Prone Coastal Lowland Of Demak Regency, Indonesia (2002-2035), Mellinia Regina Heni Prastiwi, Sigit Heru Murti Budi Santosa, Sudaryatno Sudaryatno, Daud Richard Malusu

Jurnal Pendidikan Geografi: Kajian, Teori, dan Praktek dalam Bidang Pendidikan dan Ilmu Geografi

Land use in the floodplain of Demak Regency has changed rapidly under pressure from urbanization and economic activity, and this change is hypothesized to contribute to increased flood risk, a concern reinforced by the extreme flood disaster of February-March 2024, although establishing a direct causal link between the observed land-use trajectory and the magnitude of that specific flood event would require dedicated hydrological modeling beyond the scope of this study. This study proposes examining the spatio-temporal dynamics of land use from 2002 to 2024 and forecast the conditions in 2035 utilizing a Land Change Model (LCM) framework combining Markov chains …

Assessing Coastal Vulnerability To Extreme Waves And Abrasion In Bandar Lampung City: Implications For Spatial Pattern And Infrastructure Adaptation, Adnin Musadri Asbi, Yudha Rahman, Fachri Muhammad Rasyid, Diyanti Isnani Siregar

Jurnal Geografi Lingkungan Tropik (Journal of Geography of Tropical Environments)

Coastal cities in Southeast Asia face dual challenges of rapid urbanization and increasing climate pressures, demanding robust integration of risk assessment into spatial planning. This study assesses the vulnerability of Bandar Lampung City's coastal area to extreme waves and abrasion, analyzing implications for its spatial plan. Using a standard hazard index and a spatial overlay against the city's Regional Spatial Plan (RTRW), the research identifies a 'Medium' hazard classification across all four studied sub-districts. Crucially, this classification is not driven by significant hydrodynamic forces but is substantially amplified by anthropogenic vulnerabilities. A development-centric spatial policy has led to the dominance …

Planification Against Extractivism: Towards A Democratic Agroecological Planification Against Agrarian Capitalism In A Estrada (Galicia, Spain), Jacobo Rivas Sanmartín, Rubén Camilo Lois González, Paula Noya Vázquez

Emancipations: A Journal of Critical Social Analysis

This article analyses the expansion of vineyards in the parish of San Xiao de Vea, in the municipality of A Estrada (Galicia, Spain), as a concrete manifestation of extractive agrarian restructuring under contemporary capitalism. Drawing on land-use data, socio-metabolic indicators, and qualitative testimonies, it shows how financialization, speculative land practices, and state selectivity reorganize rural space, degrade mixed farming systems, and intensify contradictions between capital accumulation and the ecological and social conditions of reproduction. The article argues that existing green planning frameworks, shaped by market logics and technocratic indicators, are structurally incapable of confronting these dynamics. As an alternative, it …

Democratic Economic Planning From And For Social Reproduction: Foundations For A Postcapitalist Research Agenda, Sophie Elias-Pinsonnault, Bengi Akbulut, Audrey Laurin-Lamothe

Emancipations: A Journal of Critical Social Analysis

As ecological and social crises render the transformation of capitalist economic organization increasingly urgent, the resurgence of interest in democratic economic planning confronts a foundational blind spot: the systematic neglect of social reproduction. This paper argues that any genuinely needs-based planned economy must extend its scope beyond formally recognized productive activities to encompass the full spectrum of reproductive labor through which human and non-human life is sustained and regenerated. Drawing on feminist political economy and the Marxist-feminist tradition, the authors argue that meeting needs requires more than reorganizing production: it demands confronting the question of who does reproductive work, at …

Unbroken Sovereignty: Land, Water, Education, And Nakoda And Oc̣Eti Ṡaḳowiŋ Tribes Of The Fort Peck Indian Reservation, 1850–1935, Richard Joseph Maska

History ETDs

This dissertation explores the intersection of sovereignty and development among the Nakoda (Assiniboine) and Oc̣eti Ṡaḳowiŋ (Sioux) Tribes of the Fort Peck Indian Reservation during the late nineteenth and early twentieth centuries. Methodologically, it draws on a critical reading of archival sources in conjunction with community input. It traces the emergence of reservation policy, government sponsored education, the imposition of allotment policy and private landownership, and the impact of state-sponsored irrigation and other development projects. I argue that the Tribes forged webs of affiliation and kinship to both assert their nationhood and navigate their involvement in such projects. These expressions …

Gradients Of Abandonment, William Tatman

Geography ETDs

As urban-rural disparities drive depopulation in rural areas worldwide, local strategies emerge as pathways for resilience. Research on Ojika, a Japanese island that has lost 75% of its population since the 1960s, reveals an Abandonment Gradient: a nuanced pattern of disuse adapted to modern polycrises. Extending the concept of "lying fallow" to homes and infrastructure, this thesis focuses on abandonment practices that reflect complex realities of labor, capital, and climate uncertainty. Rather than viewing depopulating communities as passive victims of out-migration, this paper argues they are critical sites for generating crisis response. Communally crafted attitudes toward unused space and more-than-human …

Who Bears The Burden: Tax Incidence And Water Governance In The Middle Rio Grande Conservancy District (Mrgcd) Within Bernalillo County, Michael W. Wilson

Economics ETDs

This study examines how property-value-based assessments within a large western irrigation and flood-control district distribute fiscal burdens across property owners. The empirical analysis is restricted to Bernalillo County within the Middle Rio Grande Conservancy District (MRGCD), using parcel-level administrative data from fiscal year 2025 merged with 2021 irrigation service records and geospatial information. The analysis classifies 34,397 parcels by irrigation status, agricultural valuation enrollment, and primary use to evaluate whether non-irrigating residential and commercial parcels, including renter-occupied properties that lack direct irrigation access, bear a disproportionate share of financial responsibility for a district whose first listed priority under their primary …

Understanding The Long-Run Effect Of Historical Redlining Practices, Yujian Lu

Geography ETDs

Historical redlining practices initiated by Home Owners’ Loan Corporation (HOLC) in the 1930s have produced enduring persistent socioeconomic and environmental disparities in U.S. cities. This dissertation examines their long-term impacts on social vulnerability, urban flood risk, along with public discourse about redlining practices. Results indicate that neighborhoods with HOLC grade A (greenlined) exhibit the lowest overall social vulnerability, while those graded D (redlined) face the highest across U.S. cities. In Chicago, associations between redlining practices and flood risk disparities are stronger than in Los Angeles, reflecting place-specific characteristics among environmental, socioeconomic, and demographic factors shaping flood risk disparities in long …
