Singlish Checker: A Tool For Understanding And Analysing An English Creole Language, Lee-Hsun Hsieh, Nam Chew Chua, Agus Trisnajaya Kwee, Pei-Chi Lo, Yang-Yin Lee, Ee-Peng Lim

Research Collection School Of Computing and Information Systems

As English is a widely used language in many countries of different cultures, variants of English also known as English creoles have also been created. Singlish is one such English creole used by people in Singapore. Nevertheless, unlike English, Singlish is not taught in schools nor encouraged to be used in formal communications. Hence, it remains to be a low resource language with a lack of up-to-date Singlish word dictionary and computational tools to analyse the language. In this paper, we therefore propose Singlish Checker, a tool that is able to help detecting Singlish text, Singlish words and phrases. To …

Quote: Quality-Oriented Testing For Deep Learning Systems, Jialuo Chen, Jingyi Wang, Xingjun Ma, Youcheng Sun, Jun Sun, Peixin Zhang, Peng Cheng

Research Collection School Of Computing and Information Systems

Recently, there has been a significant growth of interest in applying software engineering techniques for the quality assurance of deep learning (DL) systems. One popular direction is deep learning testing, i.e., given a property of test, defects of DL systems are found either by fuzzing or guided search with the help of certain testing metrics. However, recent studies have revealed that the neuron coverage metrics, commonly used by most existing DL testing approaches, are not necessarily correlated with model quality (e.g., robustness, the most studied model property), and are also not an effective measurement on the confidence of the model …

On The Robustness Of Diffusion In A Network Under Node Attacks, Alvis Logins, Yuchen Li, Panagiotis Karras

Research Collection School Of Computing and Information Systems

How can we assess a network's ability to maintain its functionality under attacks Network robustness has been studied extensively in the case of deterministic networks. However, applications such as online information diffusion and the behavior of networked public raise a question of robustness in probabilistic networks. We propose three novel robustness measures for networks hosting a diffusion under the Independent Cascade or Linear Threshold model, susceptible to attacks by an adversarial attacker who disables nodes. The outcome of such a process depends on the selection of its initiators, or seeds, by the seeder, as well as on two factors outside …

Modeling Of Laminar-To-Turbulent Transition Using A Hybrid Multi-Scale Simulation Strategy, Mickael Young

Masters Theses and Doctoral Dissertations

Laminar-to-turbulent transition is a phenomenon observed in practical applications. Robust computational models are needed to predict the onset of transition and the associated flow dynamics. Direct numerical simulation (DNS), although suitable for fundamental studies, tends to be computationally expensive, thus making large-eddy simulations (LES) a viable strategy. In LES, large scales of the flow field are computed, and the effects of small scales are modeled. In this study, the hybrid two-level large-eddy simulation strategy (TLS-LES) is being assessed for its ability to predict features of transition. The TLS-LES strategy blends the two-level simulation (TLS) and LES models. TLS is a …

Characterization In Satire: The Three Degrees Of Roundness; Purpose, Complexity, And Credibility, Gary Morrill-Carpenter

Masters Theses and Doctoral Dissertations

The project will attempt to explore how courtship, marriage, family, and divorce would be perceived by characters of the Greek mythos as they attempt to assimilate to a fictional Western culture through the use of satirical conventions. How would modern cultural normalities be accepted or rejected by these mythological figures? Would humanity welcome their assimilation or retaliate with prejudice? What roles do the many variations of love play in the Olympian lives as they navigate civil coexistence?

Investigation Of Gaas Double Heterostructures For Photonic Heat Engines, Nathan Giannini-Hutchin

Optical Science and Engineering ETDs

The creation of a laser cooled semiconductor device has been a long sought achievement. GaAs-based devices have emerged as a promising candidate for the realization of this goal. Efforts to improve the efficiency of such devices have enabled the material to exhibit external quantum efficiencies (EQE, a measure of the probability that an excitation leads to the emission of a photon) of 99.5\%. Despite this impressive feat, a laser coolable device remains elusive.

To investigate the obstacles to such a device, the material characteristics of GaAs-based double heterostructures (DHS) are theoretically and experimentally examined. Through this study, a GaAs $\vert$ …

Visionary Women Or Suspected Witches: The Shifting Use And Construction Of Reputation In Accusations Of Witchcraft During The High And Late Middle Ages, Megan E. Hattey

History ETDs

Throughout the high and late Middle Ages, an individual’s social acceptance and well-being were heavily dependent upon fama, or reputation, they cultivated within their communities. Women, especially, constructed and molded their reputations to protect themselves from hardship and social ostracization, allowing them a degree of agency in social situations. In this thesis, I argue that the mindful development of one’s fama was key for women to protect themselves from accusations of witchcraft. Through the lives of Hildegard of Bingen, Elisabeth of Schönau, and Jeanne d’Arc, I demonstrate how medieval reputations were built, the trifold nature it could hold, and …

Exploring Immersive Learning Experiences: A Survey, Mohammad Amin Kuhail, Areej Elsayary, Shahbano Farooq, Ahlam Alghamdi

All Works

Immersive technologies have been shown to significantly improve learning as they can simplify and simulate complicated concepts in various fields. However, there is a lack of studies that analyze the recent evidence-based immersive learning experiences applied in a classroom setting or offered to the public. This study presents a systematic review of 42 papers to understand, compare, and reflect on recent attempts to integrate immersive technologies in education using seven dimensions: application field, the technology used, educational role, interaction techniques, evaluation methods, and challenges. The results show that most studies covered STEM (science, technology, engineering, math) topics and mostly used …

Sconce Upon A Time: Evaluating Multimodal Methods Of Researching Period Lighting Technology, A Case Study Of Drayton Hall, Neale Elizabeth Grisham

All Theses

This thesis reviews several methods of researching light sources and lighting schemes from the “long eighteenth century,”[1] on a historical site. Despite the period’s cultural reliance on lighting as well as technological advancement in this era, there has yet to be published documentation on how to engage with evidence of lighting technology on historic sites for better understanding of the site’s relationship with lighting.

Using Drayton Hall in Charleston, South Carolina as a case study, this thesis outlines and demonstrates the process of five methods of investigating period lighting technology. These methods are: wall investigation, anchorage points comparison and …

The Greek Merchant Marine: A Unique Combination Of Nautical Skill And Commercial Savvy, Alexander Billinis

All Theses

The Greek-owned merchant fleet remains the world’s largest, and while plenty of histories have been written about this fleet, there is a definite absence in the historiography about why the Greeks’ relation to the sea is unique, and how this fleet came into existence. The author argues that the Greek merchant fleet is a successful hybridization of a commercial middleman minority ethos born out of conditions in the Ottoman Empire and post-independence Greece, combined with the shipping skills of a littoral people who invested in this expertise.

To understand the how and why of the Greek merchant fleet, it is …

Addressing Meloidogyne Enterolobii Spread In The Sweetpotato Industry: Development Of A High Throughput Survey Detection Method For Root-Knot Nematodes And Quantification Of M. Enterolobii Damage On Storage Roots In Long-Term Assays, Julianna Culbreath

All Theses

Meloidogyne enterolobii is an aggressive root-knot nematode (RKN) species that has emerged as a significant pathogen of sweetpotato in the Southeastern US. Meloidogyne enterolobii is spread through the movement of infected ‘seed’ sweetpotatoes used for propagation, and the RKN resistance in commercial sweetpotato cultivars has proven ineffective against this nematode. This has prompted regulatory agencies to impose quarantines on regions infected with M. enterolobii. Sweetpotato storage roots can be rendered unmarketable due to M. enterolobii infection, resulting in potential overall yield loss. Visual detection of RKN in sweetpotato can be unreliable, and further distinguishing M. enterolobii from other RKN species …

Dnp Final Report: Multimodal Pain Management To Improve Patient Satisfaction In Total Joint Replacement Patients, Dana A. Carns

DNP Final Reports

Pain is a costly result of total joint replacement (TJR) surgery. The effect of pain can extend not only to chronic medical problems for patients but also to the hospital’s bottom line by decreasing patient satisfaction. A systematic literature search was performed, and evidence was appraised that supported the efficacy of a standardized multimodal pain management protocol to decrease pain and improve satisfaction in TJR patients. The evidence-based multimodal pain management protocol was implemented during a one-month period in patients undergoing total knee or total hip replacements. Key outcomes were examined and compared to the body of evidence and to …

Analysis Of Proposed Active Radiation Shielding Design Concept For Spacecraft, Claire Mechmann

Theses and Dissertations

A need exists to protect the crew of interplanetary spacecraft from lethal doses of Galactic Cosmic Radiation (GCR) and Solar Energetic Particles (SEPs). As plans progress to send humans beyond lower Earth orbit (LEO) and outside of Earth’s protective magnetosphere, agencies involved in this endeavor find themselves confronted with the obstacle of shielding the crew from this harmful radiation. A proposed active shielding concept design has been suggested, utilizing charged dielectric capacitors to deflect incoming charged particles. This analysis will examine the feasibility of the proposed design and offer potential materials useful for application. The results should prove informative for …

Patient education is critical for the regulation of Type II Diabetes. This study evaluated 39 adults ≥ 40 years old with T2D and a HgbA1c level of ≥ 7.0%, including 27 women and 12 men aged 40 to 74. The participants were divided into two separate groups. The first group (19) diagnosed with T2D had no formal disease management education but were given videos on diabetes education to watch alone. The second group (202) was given family-inclusion diabetes education through videos. The hypothesis was that individuals who watched educational videos with family would have a more significant HgbA1c decrease than …

Examining The Effects Of Payload Type And Framing On Weather-Related Decision-Making In A Simulated Urban Air Mobility (Uam) Environment, Maria Chaparro Osman

Theses and Dissertations

The purpose of the current research study was two-fold. First, the study examined the effect of payload type on the riskiness of weather-related decision-making in a simulated urban air mobility (UAM) environment. Second, the current study examined whether framing information using prospect theory (Kahneman & Tversky, 1979) could influence the riskiness of weather-related decision-making in a simulated UAM environment. In the context of the current study, riskiness referred to the risk associated with the decision outcome, specifically whether participants selected a risk-averse decision outcome (return to the departure site) or risk-seeking decision outcome (continue to the destination site) based on …

Employment Transitions From Active-Duty Army Officer To Civilian: An Exploration Of The Knowledge, Skills, And Abilities Possessed By Combat-Experienced, Army Field-Grade Officers, James Daniel Crook

Theses and Dissertations

Two decades of wars in Iraq and Afghanistan have concluded, bringing an end to the longest military conflicts in the history of the United States of America. Following the example of post-war history, the military’s posture is to reduce personnel end-strength. The post-war military requires fewer soldiers, and a significant number of transitioning officers make the journey from military to civilian employment. This quantitative study discovered the knowledge, skills, and abilities of combat-experienced, active-duty, Army field-grade officers and explored the change from military to civilian employment. This study addressed the gap in the literature regarding this specific group of transitioning …

Faculty, Staff and Students Publications

Undescended testis (UDT) affects 6% of male births. Despite surgical correction, some men with unilateral UDT may experience infertility with the contralateral descended testis (CDT) showing no A-dark spermatogonia. To improve our understanding of the etiology of infertility in UDT, we generated a novel murine model of left unilateral UDT. Gubernaculum-specific Wnt4 knockout (KO) mice (Wnt4-cKO) were generated using retinoic acid receptor β2-cre mice and were found to have a smaller left-unilateral UDT. Wnt4-cKO mice with abdominal UDT had an increase in serum follicle-stimulating hormone and luteinizing hormone and an absence of germ cells in the undescended testicle. Wnt4-cKO mice …

Two Protestants, Three Churches: Croatian Protestantism: Churches, Denominations, And Theological Institutions, Lidija Matošević, Enoh Šeba, Ruben Knežević

Occasional Papers on Religion in Eastern Europe

Using the existing data from the national census (2011 and 2021) and other available data sources, the authors present Croatian Protestantism on the national level as a fragmented minority. In search for possible historic reasons for this fragmentized mode of existence, they proceed with an overview of Protestant presence in the Croatian lands, starting from the early adoption of Protestant ideas, eradicated by the Catholic Counter-Reformation up to the ghettoization of the Protestant congregations during the Communist era (late 20th century). The establishment of an independent Croatian state and the subsequent war proved to be a significant turning point for …

The Impact Of Game Play On Children’S Impulse Control In Early Education Settings, Sara Rodehaver

Theses

Executive functioning skills, especially impulse control, have been widely studied andinterventions have been developed to improve impulse control in young children. Play has also been studied for its benefits to young children’s development. Play skills have also been taught to students with autism spectrum disorder and attention deficit hyperactivity disorder. However, play has not often been utilized to teach impulse control directly. The current study attempted to define the components of impulse control as conditional discrimination, and to apply those discrimination skills in early childhood settings for students with no diagnosis. Kindergarten children participated in baseline measuring of conditional discrimination …

Measuring Macroeconomic Shocks Of The Covid-19 Pandemic: An Empirical Analysis For Bhutan, Lekey Dorji

Theses

Taking GDP growth and inflation as endogenous variables, this paper employs a Structural VAR from Baumeister and Hamilton (2015, 2019) to identify aggregate demand and aggregate supply shocks for Bhutan, focusing on the COVID-19 pandemic. The results suggest that 94 percent of the GDP growth plunge in 2020 is attributable to a fall in aggregate supply. The higher inflation during the COVID-19 pandemic in 2020 also implies a negative supply shock. Although the magnitudes differ, characterizing the COVID-19 pandemic in Bhutan as a supply shock coincides with preceding episodes that were also primarily driven by supply shocks.
