Research And Development Of A Laser Hot Wire Deposition Process, Christopher Croft

Masters Theses

“Laser hot wire directed energy deposition (DED) is an increasingly popular method for improving deposition rates and overall reduction of build times in DED processing. While there is clear benefit, it is important to fully understand the impact of preheating the wire. This work focuses on developing a model that describes bead geometry output using all factors including the wire preheat. The model was fit with over 150 data points that explored a large range of each factor. The resulting model was then leveraged to evaluate a process control variable. The technique chosen used feedback from the hot wire system …

Preclassic Cultural Eutrophication Of Lake Petén Itzá, Lowland Guatemala, By The Early Maya Of Nixtun-Ch'ich', Brooke A. Birkett

Masters Theses

"Paleolimnological evidence indicates the ancient Maya transformed lowland terrestrial ecosystems by felling forest vegetation to construct large civic-ceremonial centers and expand agriculture. The effects of prehistoric Maya land alterations on lake trophic status, however, remain poorly understood. We analyzed a 515-cm-long sediment core from Lake Petén Itzá, lowland Guatemala, to infer paleoenvironmental changes resulting from Maya occupation of the riparian archaeological site of Nixtun-Ch'ich'. Substantial increases in charcoal and fecal stanol concentrations indicate Maya occupation of the Candelaria Peninsula by the late Early Preclassic period beginning ca. 1400 cal yr Before the Common Era (hereafter BCE), despite scant archaeological evidence …

The Validation Of Predicted Biological Age Of Drosophila Melanogaster From Combined Statistical Modeling, Lauren Francis

Masters Theses

"Sleep is essential for maintaining a healthy body and mind and is associated with aging and aging related diseases. There are individual differences in fly as well as human sleep behavior and lifespan. Between and within individuals, sleep varies in characteristics including consolidation, rhythmicity, continuity, duration, and more. Various evidence in the literature suggests there are many molecular pathways involved with aging and they may be different for individuals. Our research is interested in a possible restorative mechanism of sleep and the ramifications of that mechanism to aging. We have developed two predictive models of aging using the fruit fly …

Seed Modeling Of An Esd Gun Discharge To A Usb Cable, Yang Xu

Masters Theses

“An IC protected by a transient voltage suppression (TVS) diode may fail if the TVS device does not turn on or does not turn on quickly enough, causing the IC to take the full brunt of the electrostatic discharge (ESD) event. Transient simulation models have been developed for ESD protection devices for the purpose of system-efficient ESD design (SEED). The TVS modeling methodology has been improved to better represent the physics that occurs during the TVS response and more accurately predict the interactions between off-chip and on-chip protection devices. Moreover, a complicated test scenario -- an ESD gun discharge through …

Axial Performance Of Self-Consolidating Concrete-Filled Fiber Tubes, Joshua David Carter

Masters Theses

"Concrete filled fiber tubes can be used to increase ductility and strength of a concrete member and self-consolidating concrete is an ideal material to use in practical applications of concrete-filled fiber tubular columns. However, the propensity of self-consolidating concrete to autogenous shrinkage could reduce the effectiveness of the concrete confinement. This research investigates the use of self-consolidating concrete in pre-cast FRP tubes and various methods of shrinkage reduction and compensation to increase the axial performance of said self-consolidating concrete-filled fiber tubes. Axial compression tests were performed under monotonic and cyclic conditions to determine the stress-strain relationship of the self-consolidating concrete …

A Systematic Analysis Of Eye-Tracking Metrics For Sleepiness, Debasis Roy

Masters Theses

”Sleepiness or sleep deprivation is a serious hazard that can be life-threatening in carrying out certain tasks (e.g., when driving or executing attention-critical tasks). Eye movement can provide cues on sleepiness. Hence, eye-tracking metrics have the potential to detect sleepiness.

In this research, we used a systematic analysis approach to identify eye-tracking metrics for sleepiness. We used several databases to identify independent experimental studies that have used eye-tracking metrics to assess sleepiness. We identified 25 studies that included 674 participants where the participants’ data were captured both in an alert state and in a sleep-deprived state. In the analysis, we …

A Meta-Analysis: Gamification In Education, Yalin Wang

Masters Theses

“Gamification has been used in a variety of contexts including education. In order to understand the effects of gamification in education, a meta-analysis was conducted. A bottom-up approach was used to analyze the effects of game design elements on learning outcomes found in the literature search. The result suggests that gamification can enhance student learning outcomes.

Overcoming The Myth Of The Contemporary “Starving Artist”: An Exploration Into The Fusion And Viability Of A 21st-Century Career In Art And Design, Miranda M. Myles Jackson

Masters Theses

This research explores the myth of the “starving artist” surrounding the pursuit of a career in the arts. Artists are often dubbed as starving due to the pre-conceived notion that careers in art do not provide longevity or financial stability. Due to this stigma, budding creatives are often dissuaded at home, school, or both from pursuing a career doing what they love. Arts programs are often cut and or remain underfunded, mainly due to this biased perception. Research indicates that careers in the arts have expanded exponentially due to its merge with various fields. According to both the STEM vs. …

Raising Consciousness: Challenging Diversity In Christian Publishing, Michael Omari Johnson

Masters Theses

The Christian publishing industry has overlooked the importance of diversity, particularly its impact on black American audiences. While studies show that diversity and inclusion can lead to more innovation through problem-solving, there persists a paradox where a lack of opportunities, disparities in wealth and employment and systemic prejudices can play a role in the ethnic and racial homogeneity of the Christian publishing industry. Thus, there are many barriers preventing people of color from emerging to the market, reflecting in the storytelling, content creation and audience of African-descent followers.

British Piracy Policy In Jamaica, Aaron M. Goins

Masters Theses

The British used piracy as a tool of empire to gain a foothold the Caribbean until they had enough resources to create an empire of their own. Piracy functioned as an insurgency for the British keeping the competition in the new world below the threshold of war in Europe but still detrimental to the Spanish. The British used this chaos and the resources it brought in to build themselves while hurting the Spanish. Then, once the British desired stability over chaos they ceased use of pirates and started hunting pirates.

He Rode Alone: Francis Scott Key As An Advocate For Freedom, Jonathan A. Richie

Masters Theses

Recently Francis Scott Key and the Star Spangled Banner have come under increasing historical scrutiny. Claims and allegations of racism and hidden meanings behind the poem have abounded and even led to statues being torn down across the nation. But what is the truth? In reality Francis Scott Key's record on race and slavery is dramatically more complex than the critics would suggest. Indeed, Key spent nearly 40 years of his life advocating in court for the freedom of slaves in Washington DC.

"Lead Us Not": Linguistic And Exegetical Considerations For Translating The Sixth Petition Of The Lord's Prayer, Brodie Allan Robinson

Masters Theses

In 2019, the Vatican announced a revision to the Italian translation of the Roman Missal, modifying the temptation petition of the Lord’s Prayer from “non ci indurre in tentazione” (“lead us not into temptation”) to “non abbandonarci alla tentazione” (“do not abandon us to temptation”). A formal, word-for-word rendering of the petition was substituted for a freer, more interpretive one. Though such a change seems insignificant, it stands at the heart of one of the most theologically contested passages in the New Testament, a passage which appears to contradict most scriptural teaching on temptation. This thesis probes the multiple problems …

Ballads like “Omie Wise,” “Pretty Polly,” and “The Ballad of Tom Dooley” have been recorded by a variety of artists, and still draw new listeners for commercial success. Despite their historic presence in American music, murder ballads are not often included in the school music curriculum. The content is not always appropriate for elementary or middle school students, but high school students are better equipped to deal with the themes and can often be …

Defining Montréal: An Exploration On The Evolution Of Montréal’S Brand And Cultural Representations Since 1930, Liliane Lai

Masters Theses

Spaces contain and create meanings through the interplay of their surrounding physical and mental landscape i.e., geography, social activity, and representation. Like many defined spaces, Montréal is not only a social and spatial manifestation of a singular community, but an ideal conceived and constructed through interpretation, objectives, and media portrayal— a mosaic or assemblage. Conceptualising Montréal as a brand being one of the cultural capitals of Canada is deeply tied to an assemblage of its diverse roots and identity beyond its history. This thesis explores the notion of city branding to understand how a city’s image and reputation evolves in …

Emily Dickinson, The Tyrant, And The Daemon: A Critique Of Societal Oppression, And The Significance Of Artistic Truth, Debra Kue

Masters Theses

This thesis argues that art, for Dickinson, was an alternative system of salvation which her society could not provide her. Unwilling to surrender herself to the mold of her society, the institutional practice of Christianity and gender expectations, Dickinson chose to take ownership of her life through art, which allowed her to develop a personal language to combat the oppressive forces of the world around her. As a conscious “revolutionist of the word” Dickinson embarked on a path of self-discovery that enabled her to conduct a life in self-imposed exile as a means to emancipate herself from the constraints of …

The Plagiarism-Proof Policy Handbook: A Multidimensional-Systems Approach To Foster Student Writing Accountability And Prevent Plagiarism In College And University Classrooms, Cynthia D. Scott

Masters Theses

Academic integrity, ethical research, and proper documentation practices are key values emphasized within most post-secondary academic communities. To support positive student outcomes, colleges and universities use honor codes, policy measures, and plagiarism detection systems to deter plagiarism, believing that the above measures promote ethical behavior from the students who graduate from their institutions. This thesis first recommends a broader, environmentally focused approach which examines the micro, mezzo, and macro levels of the post-secondary educational setting within universities and colleges using systems theory and strengths theory. It then identifies some important plagiarism barriers and plagiarism enablers students encounter within each environmental …
