Co2 Capture Utilizing Novel Deep Eutectic Solvents: Modeling, Process Simulation, And Cost Analysis, Nazneen Aspi Kolah

Masters Theses

One of the most pressing global issues that humans face is climate change caused by anthropogenic greenhouse gas emissions, especially carbon dioxide (CO2). Conventional solvents utilized for CO₂ capture, such as amines, are widely used in industrial applications due to their high CO2 absorption capacity. However, deep eutectic solvents (DES) have attracted a lot of academic attention recently due to their biodegradability and low energy for regeneration.

This research serves as a foundational proof-of-concept for using DESs in industrial gas separation processes. Five DES are evaluated for CO2 removal from flue gases. Aspen Plus is utilized to simulate the performance …

Computational Modeling In A Calculus-Based Physics Lab: Students’ Problems And Successes In Physics 2060, Abigail Sophia Flowers

Masters Theses

In the past few decades, computational modeling skills have become essential for students who want to pursue careers in physics or engineering. This issue of how to incorporate these skills into students' learning has become an important one because students in these degrees are already required to take several cognates outside of their chosen major. In 2018, Western Michigan University’s physics department decided to take on this issue by reformatting their introductory calculus-based physics labs to include computational modeling within the labs. The labs were first run in the Fall of 2018 and then were improved in spring 2019. When …

A Novel Interpretation Of Average Run Length For Assessing The Performance Of Control Charts, Gonçalo Sousa

Masters Theses

The Average Run Length (ARL) is a performance measure of Control Charts widely used within Statistical Process Control. In this study we propose a new approach for the computation of the ARL that is based on a novel interpretation of out-of-control signals produced by a Control Chart. Specifically, out-of-control signals used to calculate traditional ARLs may correspond to Type I errors and may not reflect a Control Chart’s true performance. To compensate for this issue, for Shewhart and EWMA charts, constraints are applied to the calculation of ARLs so that only out-of-control signals that occur when the corresponding statistic is …

Two Roads To Cornwall: The Cornwall, The Cornwall & Lebanon, And Gilded Age Rail Competition, Shane A. Keenan

Masters Theses

Historians have devoted much attention to the overbuilding and excessive competition among railroads in the 1880s. However, they have mostly focused on larger railroads like the Pennsylvania Railroad and the Philadelphia & Reading Railroad (Reading). Smaller railroads like the Cornwall Railroad and the Cornwall & Lebanon Railroad are less well known but play an important part in that larger story. Both railroads ran between Lebanon, Pennsylvania and Cornwall, Pennsylvania. Their primary purpose was to ship iron ore from the mines in Cornwall. Few outside of Lebanon County or Lancaster County, Pennsylvania know about these two railroads, yet they are a …

The curriculum project detailed in this study is designed to …

Settling Dust, Unsettling Ground, Olivia Newroz

Masters Theses

Understanding dust as a material system that blurs the line between ground and atmosphere, I developed a dust machine as a tool for making dust legible at the human scale. While the blurriness of ground is visualized at both particle and planetary scales, at the human scale, it becomes less evident. Drawing from Lisa’s Moffitt’s discussion of “environmental models”–that is, models that don’t merely simulate phenomena, in this case dust, but rather produce the underlying force itself––I produced visualizations of how dust, as both a grounded and atmospheric element, intertwines ground and weather across scales, through a cyclical process of …

Scientific Authorial Voice: Incorporating Explicit Instruction In Undergraduate Chemistry Courses, Emma L. Becker

Masters Theses

The effective development of undergraduate chemistry students for success in professional and academic careers involves emphases on content knowledge and on writing and authorial voice. Unfortunately, most undergraduate chemistry instruction wholly neglects writing and authorial voice instruction in favor of content knowledge instruction. This results in the development of chemistry students who know the content of their field but not how to communicate that knowledge or how to enter the chemistry discourse with their own research. This integrative review identified 71 pieces of scholarly literature and synthesized these sources to reconceptualize writing instruction in undergraduate chemistry and propose explicit instruction …

Development And Optimization Of A 1-Dimensional Convolutional Neural Network-Based Keyword Spotting Model For Fpga Acceleration, Trysten E. Dembeck

Masters Theses

Spoken Keyword Spotting (KWS) has steadily remained one of the most studied and implemented technologies in human-facing artificially intelligent systems and has enabled them to detect specific keywords in utterances. Modern machine learning models, such as the variants of deep neural networks, have significantly improved the performance and accuracy of these systems over other rudimentary techniques. However, they often demand substantial computational resources, use large parameter spaces, and introduce latencies that limit their real-time applicability and offline use. These speed and memory requirements have become a tremendous problem where faster and more efficient KWS methods dominate and better meet industry …

Assessment Of Inquiry-Based Learning Practice In Response To The Science Achievement Gap Of City Schools, Lexus K. Baxendale,

Masters Theses

Over the past few decades, many city schools have seen a decline in graduation rates, attendance, rates, and standardized test scores. Once high achieving schools, are now struggling to get students to attend school let alone graduate. One specific area that has experienced this decline is K-12 science education. As a secondary science educator working within a city district, I have witnessed firsthand the substantial gaps in knowledge that many students exhibit even as they transition into high school.

Impact Of Body Dissatisfaction And Selfies And The Effect Of Self-Compassion: A Mixed Methods Study, Amelia Jing Zhen Cheah

Masters Theses

Social media has become one of the most widely consumed platforms worldwide—specifically, the act of taking pictures of oneself otherwise known as selfies. Previous research has demonstrated links to body dissatisfaction and eating disorders about social media usage. There is a lack of research on the selfie-editing process, from taking to selecting and editing the pictures before uploading them. In turn, social media may become a risk factor for young individuals engaging in selfies and experiencing body dissatisfaction. Given how rapidly the use of social media has evolved within society, there is a constant need to address and overcome body …

The Tongue Schizochronick: Linguistic Archaism In Thomas Pynchon's Mason & Dixon, Timothy Perry O'Connor

Masters Theses

In Thomas Pynchon's novel Mason & Dixon, Reverend Wicks Cherrycoke regales his family with tales of the titular pair. The novel is written in a pastiche of late-Enlightenment-era English, which expresses an attack on modernity. Modernity, according to Pynchon, explores entropy and excludes Christ. Subjunctivity and storytelling provide a way to make contact once again with a more hopeful paradigm. The novel joins premodernity and postmodernity through its language's aurality, variability, and polysemy. The pastiche serves to undermine modernity's ambitions by satirically embracing archaic language; adopting Enlightenment parlance gestures ironically at the outmodedness the era's -theorized progress. Aurality appears in …

Half Dawn, Catherine Ashley

Masters Theses

By presenting these words on paper, I have given entry into a microcosm of recent research, questions, and creative explorations. There is potential for disconnection when trying to turn your head inside out and present it in a way that feels beautiful for other people. I’m trusting the moments of authenticity I’ve found in my wandering. Segue. Relationship. Gesture. Illusion. My musings all stem from notions of temporality. Time dances on the farthest ends of both immensity and desolation. I’ve spent stretches of time asking the people, texts, and experiments around me to define time in a way that I …

Wild Joy: An Exploration In Queer Spatial Dynamics, Kipper Thomas Reinsmith

Masters Theses

What does it mean to feel represented in a space?

What does a trans space look like?

How can we queer our interior spaces?

Our world is crafted by the many designers that have come before us. These systems, products, and spaces are built upon assumptions of the bodies that will use and occupy them—namely cisgender, able-bodied, straight folks.

Designing and creating objects as a trans person is an act of radical nature. To take up space, to design for trans luxury, for the sake of beauty, for joy itself, feels counterintuitive to the narratives we’ve been served: that of …

Technocene, Vir Joseph Naidu

Masters Theses

Embodied human communication within the Anthropocene. Existing at the intersection of technology, and the body.

The design industry has developed technology that is, paradoxically, isolating. The exposure to a vast audience in the digital sphere has introduced new societal pressures, leading to a disconnection from our immediate surroundings, detached, and donning metaphorical masks. Technocene lives on the fringes of the discipline by blending conceptual thinking with practical application. Through curious, experimental artifacts, it prompts us to shed our masks and embrace vulnerability. Technocene endeavors to reimagine the human experience by acting as a discursive design project. It probes the boundaries …

Making Room, Rachel Strompf

Masters Theses

Massachusetts is the only state in the United States with a right-to-shelter law which guarantees shelter for families with children and pregnant women.¹ As of February 2024, 3,500 homeless families with children are being sheltered in a motel or hotel with an average length of stay of 14 months, because traditional family shelters have reached capacity.^2,3 While these families are provided temporary shelter, these shelters do not allow for the development of a true sense of “home.” While a motel meets the needs of rudimentary shelter, motels were never designed as long-term accommodations and certainly not with a …

Naturify 2300, Yarina Yiwei Dai

Masters Theses

In my art practice, I explore the interplay between human desires to manipulate and anthropomorphize nature, as seen in the technological augmentation of plants and living entities. This investigation delves into how this intersection, alongside empathy towards these creations, contributes to fears of uncontrollability and the risks of addiction and excessive dependence on technology.

Bioengineering and genetic modification have cultivated unprecedented developments, allowing humans to manipulate the fundamental building blocks of life. My research speculates on this technology further, modifying the genetic code of organisms and creating bioengineered wearable entities with enhanced traits or entirely new functionalities. The primary objective …

Architecture As A Carbon-Based Practice, Qixin Yu

Masters Theses

Carbon serves as both a silent protagonist and a looming antagonist in the narrative of architecture, shaping not only the physical structures we inhabit but also the ecological legacy we leave behind.

Centuries of human exploitation of the environment have led to climate and material crises. Shifting this dynamic requires action at micro (matter), meso (material), and macro (materiality) levels. Biogenic materials offer significant potential for carbon sequestration and present opportunities for the building industry to collaborate with nature rather than merely extract from it.

This thesis establishes a research and manufacturing practice that prioritizes material innovation, carbon sequestration, environmental …

Modern Times, Will Beattie

Masters Theses

At the intersection of glass, photography and sound lies issues of perspective, framing, and information. These factors as well as the conceptual space between object and image offer an opportunity to explore the way we register narrative through contradicting signifiers. Glass historically has been used as an instrument to reveal spaces, moments, and phenomena previously imperceptible to the human eye. This rendering of previously unseen spaces through language, technology or vision, may work to reorient the viewers’ perspective and allow for a new understanding of the world. The power of disruption as a potential catalyst is central to my studio …

Revitalizing Public Spaces: Integrating Mental Exercise Into Contemporary Landscape Architecture Design, Silin Wang

Masters Theses

The most popular video games have attracted a large number of young people with their immersive digital landscapes which offer rich opportunities for active navigation and thought. This has likely led to many spending more time exploring virtual environments rather than the real, outdoor landscapes. Meanwhile, many citizens have expressed dissatisfaction with the lack of interaction and spiritual resonance in modern urban public spaces. In this context, a common criticism of Landscape Architecture is its frequent use of a formulaic design language in contemporary landscape design. Critics such as Christophe Girot argue that this approach causes landscapes to lose their …

The Future Is Over, Dotan Appelbaum

Masters Theses

History is constructed out of the narratives by which we organize the substance of all that has ever happened. Our understanding of the contemporary moment is determined by how we shape our history. The future is a promise that emerges from how we contextualize our place in time.

This thesis starts by acknowledging that the futurity promised by enlightenment liberalism is inconceivable in the face of contemporary horrors and climate catastrophe. Given this reality, what are we doing as designers? With a Benjaminian understanding of and a Foucauldian approach to history, this thesis constructs a history of design that follows …
