Nonlinear Dynamics Of Acoustic Fluctuations In One-Dimensional Ducts With And Without Unsteady Combustion, Swarnalatha Kathalagiri Vasantha Kumar
Dissertations
The overall objective of this research is to analyze the nonlinear dynamics of combustors in one dimensional Cartesian coordinate. This research was carried out in four parts, with each successive part building on the previous one. The first part begins with investigation of the coupled nonlinear evolution of acoustic modes in a quasi 1-D duct with axially inhomogeneous mean velocity and mean thermodynamic properties. A novel modification of the Krylov--Bogoliubov method of averaging (KBMA) is developed to analytically solve the modal-amplitude equations that are linearly and nonlinearly coupled with both quadratic and cubic nonlinearities. Approximate analytical solutions based on the …
The Role Of Surface Processes In Modulating Land-Sea Breeze Circulation : An Observational And Numerical Modeling Study In Java, Georgios Priftis
The Role Of Surface Processes In Modulating Land-Sea Breeze Circulation : An Observational And Numerical Modeling Study In Java, Georgios Priftis
Dissertations
In the Maritime Continent (MC), sea and land breezes (SLB), shaped by its numerous islands, are key drivers of the tropical climate. Island morphology, terrain, land cover, and orientation relative to prevailing winds affect these breezes and associated convection. While research has largely focused on larger islands, smaller islands like Java remain understudied. Java features a mountainous chain with several gaps and experienced significant land use and land cover changes (∆LULC) over the past two decades. This dissertation aims to: 1) adapt observational methods to detect mesoscale boundaries in numerical models, 2) analyze the role of Java’s topography and cloud- …
Hydrogen Molecule Adsorption On Heptazine Carbon Nitride Nanosheet Decorated Rh, Ir, Pd, And Pt Elements For Hydrogen Storage Application, Piyawat Amornthatri
Hydrogen Molecule Adsorption On Heptazine Carbon Nitride Nanosheet Decorated Rh, Ir, Pd, And Pt Elements For Hydrogen Storage Application, Piyawat Amornthatri
Chulalongkorn University Theses and Dissertations (Chula ETD)
In this work, the hydrogen storage and sensing potential of pristine and metaldecorated heptazine carbon nitride nanosheets (hg-C3N4-NS) was investigated using density functional theory (DFT) calculations. Decoration with platinum-group metals-Rh, Ir, Pd, and Pt-was examined in two stable configurations: an off-center coordination site (Group 1) and a pore-center site (Group 2). Hydrogen adsorption was studied stepwise from one up to three H2 molecules per system to simulate the natural accumulation process. The results revealed that pristine hg-C3N4-NS exhibits only weak physisorption, whereas metal decoration markedly enhances adsorption strength. Among all systems, Ir-hg-C3N4-NS1 and Rh-hg-C3N4-NS1 showed the most exothermic adsorption energies …

Hypothetical Mistakes: Hedging Wrong Answers With Conditional Language., Jessica Sujata Chandras
Hypothetical Mistakes: Hedging Wrong Answers With Conditional Language., Jessica Sujata Chandras
UNF Faculty Research and Scholarship
This article analyzes American high school students hedging incorrect responses to teacher-initiated questions in IRE (Initiation-Response-Evaluation) format using conditional language and hypotheticals in ways that facilitate an affiliative stance between students and their teacher. Scholarship on hedging details its use to approximate responses as a shield against doubt and criticism or as collaborative communication, whereas stance is a grammatically encompassed expression of attitudes related to the content of a message. This study brings together theories of stance, hedging, and conditional language use to outline how errors can be a student-initiated pedagogical tool to deepen explanations and engagement. To broaden understanding …
A Generalization Of The Graham-Pollak Tree Theorem To Even-Order Steiner Distance, Joshua Cooper, Gabrielle Tauscheck
A Generalization Of The Graham-Pollak Tree Theorem To Even-Order Steiner Distance, Joshua Cooper, Gabrielle Tauscheck
Faculty Publications
Graham and Pollak showed in 1971 that the determinant of a tree’s distance matrix depends only on its number of vertices, and, in particular, it is always nonzero. The Steiner distance of a collection of k vertices in a graph is the fewest number of edges in any connected subgraph containing those vertices; for k = 2, this reduces to the ordinary definition of graphical distance. Here we show that the hyperdeterminant of the kth order Steiner distance hypermatrix is always nonzero if k is even, extending their result beyond k = 2. Previously, the authors showed that the k-Steiner …
Conceptualizing Language Ideologies About Education: Exploring Perceptions Of Multilingualism Among Marathi Speakers From India, Priya M. Dabak, Jessica Sujata Chandras
Conceptualizing Language Ideologies About Education: Exploring Perceptions Of Multilingualism Among Marathi Speakers From India, Priya M. Dabak, Jessica Sujata Chandras
UNF Faculty Research and Scholarship
Perceptions of multilingualism have an impact on the educational choices of urban Indians and larger policy decisions around language in education in the Indian state of Maharashtra. By surveying 150 speakers of Marathi, the official language of the state and mother tongue, or first language of survey respondents, perceptions of multilingualism reveal conceptual assumptions and biases that can be uncovered through cognitive-linguistic analysis. Unprompted, survey respondents drew connections between multilingualism and education, underscoring language ideologies, or beliefs about languages which motivate urban Maharashtrians' educational decisions. Education is the stage upon which multilingual speakers in India express their aspirations and anxieties …
Collectivism And Efficacy: Relationship To Academic Performance In Early Adolescents, Richvinder Kaur
Collectivism And Efficacy: Relationship To Academic Performance In Early Adolescents, Richvinder Kaur
Selected Full-Text Master Theses 2021-
This study explored the mathematics efficacy beliefs of 270 South Asian (Indo American) immigrant and Anglo American nonimmigrant 7th grade students. Self-efficacy beliefs strongly predicted mathematics performance for both cultural groups, but there were differences between the 2 groups in the sources of self-efficacy, the predictiveness of the secondary motivation variables. It is argued that the Indo American students are more vertical or hierarchical than the Anglo-American students and that comparison with others strongly influences their motivation beliefs and the formation of their efficacy beliefs. Self-efficacy in some cultures may be more other-oriented than is typically seen in Western cultures. …
Long Term Trends In Mortality Rates Of A Smallmouth Bass Population, Caleb D. Anderson
Long Term Trends In Mortality Rates Of A Smallmouth Bass Population, Caleb D. Anderson
Journal of Earth and Life Science
Smallmouth bass Micropterus dolomieu are known as a popular sport fish for anglers. When a known smallmouth bass fishery appears to have a dwindling population, it raises questions about the population health. A common indicator of the health of the population is the mortality rate. By comparing mortality, conclusions can be made on whether smallmouth bass are dying at a different rate in the system over time. Therefore, the objective of this study was to see if there had been a significant change in smallmouth bass mortality over a span of thirty years in Round Lake (DOW:010204), Aitkin County, Minnesota. …
The Effects Of Length, Weight, Age, And Gender On Mercury Concentrations In Burbot In North-Central Minnesota Lakes, Liam Hanley
The Effects Of Length, Weight, Age, And Gender On Mercury Concentrations In Burbot In North-Central Minnesota Lakes, Liam Hanley
Journal of Earth and Life Science
Burbot Lota lota in north-central Minnesota lakes have the potential to reach large sizes and consume large volumes of prey. This caveat may make burbot susceptible to higher rates of biocontamination, bioaccumulation and biomagnification. The objective of this study was to determine how changes in age, length, gender, weight, and lake affect total mercury concentrations in burbot. In this experiment 28 burbot were angled from three lakes: Cass (n = 17), Winnibigoshish (n = 4), and Bad Medicine (n = 7). Then tissue samples were taken from each fish and were lyophilized and homogenized. Homogenized tissue samples were analyzed by …
Relationship Between Fishing Hours And Number Of Fish Harvested From Upper Red Lake, Dylan Ohlenkamp
Relationship Between Fishing Hours And Number Of Fish Harvested From Upper Red Lake, Dylan Ohlenkamp
Journal of Earth and Life Science
Total hours fishermen spend fishing and total amount of fish harvested per year are some of the most important pieces of knowledge gained from creel surveys. They provide crucial information that assesses fisheries mortality and pressure. MN DNR uses their results from creel surveys to improve or impose regulations, and to maintain healthy fisheries. Based on results from similar studies, there is expected to be a positive relationship between hours fished and fish harvested. To determine the relationship between these two variables on Upper Red Lake, data from two years were selected when the variables were at their highest and …

A Domain-Agnostic Neurosymbolic Approach For Big Social Data Analysis: Evaluating Mental Health Sentiment On Social Media During Covid-19, Vedant Khandelwal, Manas Gaur, Ugur Kursuncu, Valerie L. Shalin, Amit P. Sheth
Psychology Faculty Publications
Monitoring public sentiment via social media is potentially helpful during health crises such as the COVID-19 pandemic. However, traditional frequency-based, data-driven neural network-based approaches can miss newly relevant content due to the evolving nature of language in a dynamically evolving environment. Human-curated symbolic knowledge sources, such as lexicons for standard language and slang terms, can potentially elevate social media signals in evolving language. We introduce a neurosymbolic method that integrates neural networks with symbolic knowledge sources, enhancing the detection and interpretation of mental health-related tweets relevant to COVID-19. Our method was evaluated using a corpus of large datasets (approximately 12 …
