Multi-Script Handwriting Identification By Fragmenting Strokes, Joshua Jude Thomas

Graduate Theses and Dissertations (2019 - present)

This study tests the effectiveness of Multi-Script Handwriting Identification after simplifying character strokes, by segmenting them into sub-parts. Character simplification is performed through splitting the character by branching-points and end-points, a process called stroke fragmentation in this study. The resulting sub-parts of the character are called stroke fragments and are evaluated individually to identify the writer. This process shares similarities with the concept of stroke decomposition in Optical Character Recognition which attempts to recognize characters through the writing strokes that make them up. The main idea of this study is that the characters of different writing‑scripts (English, Chinese, etc.) may …

Exploring The Relationship Between Anxiety And Virtual Reality Sickness, David Wesley Woolverton

Graduate Theses and Dissertations (2019 - present)

As virtual reality (VR) becomes more commonly used in education, it is important to understand the technology’s weakness and mitigate any potential negative effects on student success. One adverse side-effect of VR use is simulation-induced motion sickness, known in the context of VR as VR sickness. Previous research by Howard and Van Zandt (2021) found that possessing a phobia had a significant positive correlation with VR sickness, but only if the phobia is triggered by the simulation, suggesting that symptoms are actually connected to the anxiety the phobia induces. This study explored the hypothesized correlation between anxiety and VR sickness, …

We then show how the model parameters are set using statistical measures for hypothesis testing.

Utilizing Electrical Geophysical Methods To Map Mycorrhizal Mycelium Networks Non-Invasively, Donald Pesonen

Graduate Dissertations and Theses

Mycorrhizal mycelium networks are a key component to forest health. These networks act as a transportation system for nutrients, are major players in carbon and nitrogen cycling, and can provide some level of drought resistance to the surrounding flora. Due to the location and size of these network’s filaments, studying mycelium non-invasively has been difficult. The alternative method of laboratory grown samples, lacks the important environmental factors that play into the growth and development of mycelium. Mycelium’s inherent conductivity and moisture retention allows for these networks to be a viable target for electrical geophysical equipment. CMD-Tiny, a small shallow depth …

"Speak Arabic!": Arabic Dialect Comparison Videos And The Reconfiguration Of The Maghreb-Mashreq Language Ideology, Jacquelyn Stewart-Kuhn

Honors Theses

There is a hidden power imbalance in the Arabic-speaking world. It is not related to warfare, politics, or oil, but language. For decades, Egyptian and Levantine (Mashreqi) dialects have been over-represented in Arabic language media, to the detriment of North African (Maghrebi) dialects. This imbalance has played a crucial role in reinforcing what Hachimi (2013) refers to as the “Maghreb-Mashreq language ideology,” i.e. the belief that Mashreqi dialects are superior to Maghrebi dialects. Yet in an era of social media, Mashreqi voices and dialects are becoming less dominant, and Arabic-speakers across the region are being increasingly exposed to Maghrebi voices …

Impact Of Perinatal Escitalopram Exposure On Adolescent Behavior, Jessica Bezenah - Bottorff

Electronic Theses, Projects, and Dissertations

Escitalopram (EST), a selective serotonin reuptake inhibitor (SSRI), is an antidepressant frequently used during pregnancy, yet there is limited knowledge of its long-term effects on maternal use. Past studies suggest that maternal exposure may adversely affect the fetus, which may be due to the hyperserotonergic environment caused by the nature of SSRIs during early development. Modifications of the serotonergic system in offspring during certain critical periods of development may result in long-term behavioral and cognitive changes in adulthood. Further, recent human studies have demonstrated that prenatal exposure to SSRIs in humans may increase susceptibility to autism spectrum disorder (ASD) and …
