Disrupting Monotony, Elias Mendez

Bachelor of Architecture Theses - 5th Year

At the start of this project, I was confronted with a range of global issues that revealed the harsh realities many regions face in securing basic human needs, particularly shelter. One issue that stood out to me was the housing crisis in Mexico, where low-income families often struggle to afford homes while also meeting essential needs like food and clothing. Many of these homes are poorly constructed due to strict budget constraints and are built in such close proximity that both private and communal spaces are sacrificed in favor of maximizing land use. This often results in rows of identical …

Plastic Repurposed: Explorations For The Use Of Plastic Waste As An Architectural Element, Caleb Tinajero

Bachelor of Architecture Theses - 5th Year

The business model for plastic has become accustomed to a system of consumption and disposal that has failed to develop a way that benefits the environment. Unless the production of plastic ceases to persist, the number of plastic waste will continue to grow and even though it is not fully visible, the effects of this pollution will eventually contaminate the aspects of our lives. Although stopping the production of such a vital factor to the prosperity of the economy is unrealistic, it could also be detrimental to the machinations of society. It is after all a very useful resource. The …

Urban Eden, Establishing The Groundwork For A More Resilient City, Max R. Oliva

Bachelor of Architecture Theses - 5th Year

Cities account for over 70% of Global C02 emissions and as these areas grow over time their Carbon Footprint will grow in turn. In order to offset this imbalance I propose to design Performative Skins & Building Modules to not only reduce the carbon footprint in these cities, but also recover their connection to Nature contributing not only to energy efficiency and air quality, but also to urban aesthetics, the inclusion of these systems could go so far as to help mitigate the heat island effect and in the long term help establish a more resilient and sustainable city

Characterization Of A Magnetically Contained Hot Filament Plasma Source With A Wide-Sweeping Langmuir Probe, Jonas Rowan

Doctoral Dissertations and Master's Theses

Ionospheric plasma research in the Space and Atmospheric Instrumentation Laboratory’s Space Plasma Chamber has been hindered by the lack of a suitable plasma diagnostic instrument and understanding of its hot-filament plasma source. This thesis describes efforts made to remedy both problems. A wide-range Sweeping Langmuir Probe was developed with a ±35 V sweeping range to fully analyze ion and electron saturation regions in the entire IV curve. A method was derived to estimate the chamber source’s filament temperatures. The new Langmuir probe was integrated into a refurbished automated system designed in Python to measure plasma parameters for various chamber conditions, …

Solar Sailing Adaptive Control Around The Earth-Moon Lagrange Point L4 For Stellar Observations, Luis Mendoza Zambrano

Doctoral Dissertations and Master's Theses

To expand our knowledge about the influence of the Sun in the cislunar region, as well as our understanding of shocks due to Coronal Mass Ejections and large coronal magnetic reconnection, a solar sailing approach is proposed to separately capture lunar occultations and observe the solar corona from L₄ of the Earth-Moon system. Single and multiple shooting techniques are described along with a pseudo arc-length continuation method for preliminary orbit design. Periodic orbits in the vicinity of L₄ are obtained in the context of the Earth-Moon circular restricted three-body problem (CR3BP) and the Sun-Earth-Moon bi-circular restricted four-body problem …

Satellite Reorientation Using Reinforcement Learning Under Unknown Attitude Failure, Matthew Willoughby

Doctoral Dissertations and Master's Theses

This study presents a reinforcement learning (RL) approach for reestablishing communication with deep-space satellites under unknown attitude determination and control system (ADCS) failures. When traditional fault-tolerant control methods cannot restore signal, the proposed RL controller acts as a last-resort measure by autonomously reorienting the satellite’s antenna toward Earth while charging the battery via solar panels. A generic reward function, designed for the RL-based method, enables the controller to adapt to diverse failure scenarios, including severe actuator noise, misalignment, and complete actuator failure. Simulations are conducted in the Basilisk environment and trained with the tonic framework and demonstrate ranging capabilities of …

Northern Humboldt Indians: History Of Humboldt County People And Places, Jerry Rohde

Trade & Scholarly Monographs

In what is now Humboldt County and southern Klamath County, seven Indian tribes made their home: the Mawenok, Whilkut, Tsnungwe, Hupa, Karuk, Yurok, and Wiyot. They arrayed themselves upon the land and sent their roots down into the earth, so that they had become as one with the place. Their villages were of long standing, and even their individual houses could sometimes be traced back, by name, for hundreds of years. In 1850, whites arrived on the shores to rage like a gale across the land. For 15 years the gale would sweep up the rivers and over the ridges …

Developing A Protective Pcm Layer For An Aluminum Sheet, Rachel Foulk

Mechanical Engineering and Materials Science Independent Study

As electric vehicles (EVs) become increasingly prevalent, improving the thermal safety of battery systems is essential. This study investigates the development of a high-temperature-resistant coating for aluminum sheets, aimed at mitigating thermal runaway events by incorporating carbonate-based phase change materials (PCMs). Using a PTFE binder and calcium carbonate as the primary PCM, the coating was applied via airbrush to maintain a thin, even layer. Initial results showed the coating was thermally resilient but suffered from poor adhesion and mechanical strength, as demonstrated by failed hardness tests and inconsistent thermoconductivity data. Surface etching with sulfuric acid improved visual adhesion, suggesting potential …

Soft Modular Robots: From Modular Tensegrity Structures To Bioinspired Sea Robots, Luyang Zhao

Dartmouth College Ph.D Dissertations

The rapid advancement of robotics necessitates systems capable of adapting to complex, unstructured environments. Soft robots, with their flexibility and compliance, excel in delicate interactions, making them ideal for medical applications and search-and-rescue missions. Modular robots, on the other hand, offer reconfigurability, enabling diverse task-specific adaptations in dynamic settings. Despite their individual advantages, the integration of soft and modular robotics remains underexplored. This proposal aims to develop soft modular robots that combine the adaptability of soft robotics with the versatility of modularity. These systems will be capable of autonomously transitioning between locomotion, manipulation, and infrastructure assembly across land, water, and …

This thesis critically examines Félix Régamey’s transformative role in the development of Japonisme, highlighting his pivotal contribution to bridging Western perceptions and authentic Japanese culture during the late nineteenth century. Through an exploration of his firsthand experiences in Japan, Régamey emerges as a multifaceted and paradoxical figure—an artist, educator, and author—whose pursuits reshaped the narrative of Japanese art and cultural exchange in France amid the fervor of Japonisme. His immersion in Japanese society enabled him to engage directly with its artistic traditions, which he skillfully translated for European audiences. This study reveals Régamey’s efforts to challenge the prevailing Orientalist stereotypes …

Emotional Labour In The Boundary Work Of Filipino Transnational Workers In Indian Cities, Jozon A. Lorenzana

Department of Communication Faculty Publications

This article examines the boundary work undertaken by Filipino transnational workers in globalizing Indian cities. While the ‘practice turn’ in boundary studies has shed light on boundary work's mundane and performative dimensions, the role of emotions in performing such work needs to be ascertained. To account for both the performative and emotional dimensions of boundary work, I present an ethnographic study on Filipino professionals in India that engages Hochschild's concept of emotional labour. Since the mid-2000s, local and multinational companies have hired Filipino professionals to set up businesses and manage operations. I examined their practices of boundary work through in-depth …

Lifespan Reference Curves For Harmonizing Multi-Site Regional Brain White Matter Metrics From Diffusion Mri, Alyssa H Zhu, Talia M Nir, Shayan Javid, Julio E Villalón-Reina, Amanda L Rodrigue, Lachlan T Strike, Greig I De Zubicaray, Katie L Mcmahon, Margaret J Wright, Sarah E Medland, John Blangero, David C Glahn, Peter Kochunov, Douglas E Williamson, Asta K Håberg, Paul M Thompson, Neda Jahanshad

Faculty, Staff and Student Publications

Age-related white matter (WM) microstructure maturation and decline occur throughout the human lifespan, complementing the process of gray matter development and degeneration. Here, we create normative lifespan reference curves for global and regional WM microstructure by harmonizing diffusion MRI (dMRI)-derived data from ten public datasets (N = 40,898 subjects; age: 3-95 years; 47.6% male). We tested three harmonization methods on regional diffusion tensor imaging (DTI) based fractional anisotropy (FA), a metric of WM microstructure, extracted using the ENIGMA-DTI pipeline. ComBat-GAM harmonization provided multi-study trajectories most consistent with known WM maturation peaks. Lifespan FA reference curves were validated with test-retest data …

Immigrants Reduce Unionization In The United States, Town Oh, Alex Nowrasteh

School of Business and Leadership Working Papers

Since the 1960s, U.S. union density has consistently dropped as the immigrant share of the population has risen. Using the Naylor and Cripps (1993) model of union formation, we argue that immigrants lower unionization by increasing diversity in the working population that, in turn, reduces solidarity and by having lower preferences for unionization. Empirically, we employ the skill-cell method devised by Borjas (2003) over the 1994-2020 period. Immigration can explain 30 percent of the decline in union density from 1994-2020.

Origami Lunar Habitation Unfolding A Future Colony In Space, Andrew Fields

Bachelor of Architecture Theses - 5th Year

What is origami? Origami is the ancient Japanese art of folding paper into decorative pieces. Today we use origami as a way to compact things for better storage or transportation and still to create decorative pieces of art. Origami is a must in space travel as it allows for large satellites to be folded and compacted down into a rocket and then unfolded in space to allow for the most surface area for solar absorption.

How can origami help? By making it possible to create lightweight, expandable structures that can be used in alien environments and by enabling the repair …

Blood Architecture : Designing A Hemophilia Treatment Center Through Biomimetic Principles, Melissa Da Costa Schmidt

Bachelor of Architecture Theses - 5th Year

This thesis explores how biomimetic principles drawn from the blood clotting process can inform the architectural design of hemophilia treatment centers, enhancing their efficiency, adaptability, and patient-centered care. By paralleling the phases of hemostasis—platelet aggregation, clotting factor activation, and fibrin stabilization—with spatial functions, the design proposes a layout where acute care areas are centrally positioned for rapid response, while rehabilitation zones support long-term healing, mirroring the reinforcement phase of clotting. Regulated movement and spatial zoning echo the precise control of clot formation, promoting accessibility, privacy, and reduced congestion. Architectural forms inspired by vascular networks, combined with the use of natural …

Rare Earth Mineral Flotation – A Comparison Of Silicates To Oxides, Carbonates And Phosphates, Abdul Mamudu

Graduate Theses & Non-Theses

Flotation is a processing method used to separate valuable minerals from gangue minerals based on differences in hydrophobicity. When applied to ores bearing rare earth minerals (REMs) variations in rare earth element (REE) concentrations within the REMs can lead to inconsistent flotation results. Prior work at Montana Technological University examined the adsorption of collectors on the surfaces of synthetic REMs to assess recovery via flotation. Previous studies showed that the results obtained for Salicyl Hydroxamic Acid (SHA) on rare earth oxides REO), rare earth carbonates (REC), and rare earth phosphates (REP) vary depending on the coordination number (CN) and the …

A Proposed Metals Recovery Assessment Protocol To Evaluate Mine Waste For Critical Minerals And Rare Earth Recovery Prior To Site Remediation, Claire Mbia

Graduate Theses & Non-Theses

The Metals Recovery Assessment (MRA) protocol involves collecting and evaluating information to assess the possibility for recovery of critical or rare earth minerals at mine sites to offset remediation or redevelopment costs associated with land reuse at Superfund or closed mine sites. This protocol provides a tool to implement metals recovery in conjunction with property reuse, and may involve a review of available records, visual inspections of the site, sample collection and discussions with local government officials and community members. The selection for metals recovery would be intended to both achieve metals reduction which may be required for the protection …

Real-Time System Availability For Cyber-Physical Systems, Jinwen Wang

McKelvey School of Engineering Graduate Student Theses & Dissertations

Cyber-physical systems (CPSs), such as autonomous vehicles, are increasingly being deployed. The sensing, control, and actuation loop in CPSs must complete within strict timing constraints. Missing a real-time deadline can lead to catastrophic consequences, as CPSs continuously interact with the physical world. This highlights the importance of real-time system availability (i.e., timely execution) in CPS tasks, going beyond traditional security goals that primarily focus on confidentiality and integrity. From a security perspective, two factors affect real-time system availability. First, attackers with access to hardware resources in CPSs may disrupt the execution timing of real-time tasks. Second, the deployment of security …

Single-Cell Analysis Of Clonal And Transcriptional Dynamics During Direct Reprogramming, Brent Biddy

Arts & Sciences Graduate Student Theses and Dissertations

Direct lineage reprogramming converts one cell type into another, a process characterized by significant heterogeneity. Single-cell genomic techniques have been instrumental in dissecting this variability, yet they often fail to preserve lineage relationships. Here, I present CellTagging, a sequential, combinatorial indexing method that enables the reconstruction of clonal history and gene expression dynamics at single-cell resolution. This facilitates the construction of multi-level lineage trees, providing insights into cellular reprogramming trajectories. We applied CellTagging to investigate direct lineage reprogramming of mouse embryonic fibroblasts into induced endoderm progenitors. Our analysis revealed two distinct reprogramming trajectories: one leading to successful conversion and another …

Effects Of Angptl3 Deficiency On The Regulation Of Hepatic Lipoprotein Production And Lipid Metabolism, Kendall Helene Burks

Arts & Sciences Graduate Student Theses and Dissertations

Cardiovascular disease is the leading cause of death worldwide. A major treatment goal is to lower plasma lipids, especially low-density lipoprotein cholesterol (LDL), the cardinal risk factor for coronary artery disease (CAD). Patients with familial hypercholesterolemia (FH) experience early-onset CAD due to extremely high LDL. Underdiagnosis and undertreatment of FH are exacerbated by limited therapeutic options. However, one strategy has successfully lowered LDL in FH patients: Inhibition of the hepatically secreted protein Angiopoietin-like protein 3 (ANGPTL3). Despite promising clinical data, the mechanism by which ANGPTL3 inhibition lowers LDL has not been fully described. Although ANGPTL3 has been shown to modulate …

Functional Diversification Of Rice Ago1 Proteins, Rachel Elie Jouni

Arts & Sciences Graduate Student Theses and Dissertations

Global demand for food is outpacing gains from conventional plant breeding. Scientists have turned to molecular crop breeding techniques to increase crop output and mitigate global hunger; however, a common setback in this process is the pleiotropic effects of target genes. We need to develop strategies to specifically modulate desired traits without incurring undesired penalties. Natural evolution frequently balances such tradeoffs through extensive regulation, which we can leverage to produce more specific results. Reproductive development is an important target of breeding efforts due to its direct effect on yield. Rice, a major staple food crop for half the world’s population, …
