X-Band Rf Transmitter Design For Multi-Purpose Small Satellite Communication Operations, Omer F. Gumus

Master's Theses

This thesis provides a description of the analysis, design, and tests of an X-band RF Transmitter communication system for small satellites. X-band transmitter systems are becoming popular in the upcoming deep space missions. Most of the deep-space ground stations have been using X-band frequencies to receive or transmit signals. The X-band (<10 GHz) can offer lower atmospheric losses and up to a couple of Mbps data rates for multiple satellite operations. Nowadays, many small satellites have been using frequency bands such as VHF, UHF, L, and S-band frequencies for communication. From deep space to the ground station, the low-frequency ranges are inadequate in providing Mbps level data rates and enough bandwidth for deep space missions.

The main focus of this thesis was the development of the subsystems such as gain block amplifier, Mixer, Bandpass Filter, and RF power amplifier. The subsystems were designed separately, then they were connected together to perform an end-to-end system test. One of the thesis aims is to design …

A Network Analysis Of Covid-19 In The United States, Joseph C. Mcguire

Master's Theses

Through methods in network theory and time-series analysis, we will analyze the spread of COVID-19 in the United States by determining trends in state-by-state daily cases through a network construction. Previous researchers have found frameworks for approximating the spread of the COVID-19 pandemic and identifying potential rises in cases by a network construction based on correlation of cases between regions [1]. Applying this network construction we determine how this network and its structure act as a predictor for overall COVID-19 cases in the United States by preforming a trend analysis on a variety of network statistics and US COVID-19 cases.

In-Situ Defect Detection Using Acoustic Vibration Monitoring For Additive Manufacturing Processes, Ali Harake

Master's Theses

The world of additive manufacturing revolves around speed and repeatability. Inherently, the process of 3D printing is plagued with variability that fluctuates with every material and parameter modification.

Inaccessible Interpolated Imagery: How Coffee Farmers In The State Of Chiapas Might Access Political Economic Opportunity Through Representation, Paolo Fiann Bicchieri

Master's Theses

Here is a useful parable to boil down the idea of this project and set the tone: when one goes to the bar to tell a story about a fight at the bar, they would never venture to place themselves as the hero of the brawl, taking out three drunkards in a single punch, unless they were really in the bar, at that time, fighting a good fight. One would never do this as the bartender, locals, and regulars would all know if this were the case or not. Yet transnational corporations, governments, and even consumers do this all the …

I believe one facet of this can be found in the adoption of the normative framework of a Right to Assist …

Let’S Bring Intersectional Environmentalism To The Classroom: A Qualitative Study Upon Voices Of Intergenerational Asian American Activists, Michelle P. Sun

Master's Theses

Climate change and environmental pollution have been threatening people’s lives in recent years. Many educators and environmentalists have called for environmental justice education. However, most of the dominant mainstream forms of environmental education perpetuate environmental injustice, continue systemic oppression of marginalized communities, and do not lead to the needed transformation. Neoliberalism makes environmental education individualistic, and education for environmental justice requires cultural recognition. Additionally, the environmental contribution from Asian American communities is always marginalized. My paper conducted semi-structured interviews with three Asian American environmental activists.

The Mythos Of Lilith: A Collection Of Madwomen, Megan Mau

Master's Theses

For too long, women’s stories have been mitigated, translated, truncated, and censored, if they were even recorded at all before the world could hear them. What could women be writing that would be so threatening to incite such censorship? To a male-dominated world, anything that could disrupt their illusions of power is a threat. If a woman penned a narrative of her experiences in this world, or if she were to begin speaking on a new way of thinking that called for change, that must be stopped. The ultimate goal is to prevent women from writing or stepping out of …
