Algorithms For The Optical Profiling Of The Atmospheric Limb Radiometry Data Analysis For The Opal Cubesat, Eric D. Ashby

Physics Capstone Projects

The Optical Profiling of the Atmospheric Limb (OPAL) mission is a CubeSat (NSF) project with aims to measure the temperature in the thermosphere between 90 and 140 km. The temperatures are inferred from the characteristic emission lines of molecular oxygen called the O2 A-band (around 760 nm). These temperatures will be used to better understand the evolution of the upper atmosphere during a solar storm and to analyze the temperature signatures of gravity waves. Multiple steps are required to retrieve temperature data from the OPAL satellite. Initially, the data must be deconvoluted from line-of-sight images. Spectral data must then be …

Photocatalytic Properties Of G-C3n4–Tio2 Heterojunctions Under Uv And Visible Light Conditions, Rachel Fagan, Declan Mccormack, Steven J. Hinder, Suresh Pillai

Articles

Graphitic carbon nitride (g-C3N4) and titanium dioxide (TiO2) were chosen as a model system to investigate photocatalytic abilities of heterojunction system under UV and visible light conditions. The use of g-C3N4 has been shown to be effective in the reduction in recombination through the interaction between the two interfaces of TiO2 andg-C3N4. A simple method of preparing g-C3N4 through the pyrolysis of melamine was employed, which was then added to undoped TiO2 material to form the g-C3N4–TiO2 system. These materials were then fully characterized by X-ray diffraction (XRD), Brunauer Emmett Teller (BET), and various spectroscopic techniques including Raman, X-ray photoelectron …

A Unifying Framework In Vector-Valued Reproducing Kernel Hilbert Spaces For Manifold Regularization And Co-Regularized Multi-View Learning, Hà Quang Minh, Loris Bazzani, Vittorio Murino

Dartmouth Scholarship

This paper presents a general vector-valued reproducing kernel Hilbert spaces (RKHS) framework for the problem of learning an unknown functional dependency between a struc- tured input space and a structured output space. Our formulation encompasses both Vector-valued Manifold Regularization and Co-regularized Multi-view Learning, providing in particular a unifying framework linking these two important learning approaches. In the case of the least square loss function, we provide a closed form solution, which is obtained by solving a system of linear equations. In the case of Support Vector Machine (SVM) classification, our formulation generalizes in particular both the binary Laplacian SVM to …

Mathematical Models For Infectious Disease Transmission With Stochastic Simulation Of Measles Outbreaks, Valerie Welty

Honors College Theses

As they are the leading cause of death among children and adolescents worldwide, it is of extreme importance to control the spread of infectious diseases. Information gained from mathematical modeling of these events often proves quite useful in establishing policy decisions to accomplish this goal. Human behavior, however, is quite difficult to recreate when using equations with pre-determined results, such as deterministic differential equations often used with epidemic models. Because of this, the focus of the research was to create a simulation of an outbreak, specifically of measles, by using an imaginary population experiencing simulated stochastic events on a discrete …

Doxycycline Resistance In Plasmodium Falciparum Linked To Single Nucleotide Polymorphisms In The Plasmodium Falciparum Apicoplast Small Subunit Ribosomal Rna (Pfssrrna) Gene, Amanda Wasko

Scholarly and Creative Works Conference (2015 - 2021)

Plasmodium falciparum, a protozoan parasite known as malaria, widely impacts human health; thus antimalarial drug investigations are critical. Doxycycline is a commonly used antimalarial prophylactic, but its mechanism of action is unclear. In prokaryotes, doxycycline works as an antibacterial by disrupting protein translation via the small subunit ribosome. Interestingly, P. falciparum has a small subunit ribosome of prokaryotic origins in the apicoplast, a plastid-like organelle. Therefore, we hypothesized that doxycycline works in P. falciparum by inhibiting protein synthesis via the small subunit ribosomal RNA and that mutations in the gene encoding the P. falciparum apicoplast small subunit ribosomal RNA …

Instruments Of Knowledge: Music And The Brain, Anne R. Stoklosa

The Review: A Journal of Undergraduate Student Research

There is little doubt that music plays an important role in cultures all over the world and is an interconnected piece of every society. More specifically, actively engaging in the music by playing a musical instrument, particularly at a young age, has been a hot topic in neuroscience in recent decades. Playing a musical instrument has been shown to increase cognitive ability through enhanced neuronal communication between the left and right hemispheres of the brain, resulting in positive effects on learning, memory, fine motor skills, verbal and non-verbal reasoning, resulting in an overall more capable brain to apply in a …

Strengthening Early Mathematical Foundations: Number Recognition, Mary C. Burns

University of Montana Conference on Undergraduate Research (UMCUR)

Children enter elementary school with a diverse range of mathematical understanding, and students’ preliminary mathematical experiences can have a lasting effect on their self efficacy and attitudes towards school. Number recognition is an essential skill of early numeracy that allows for students to develop a strong mathematical foundation to build upon, and instructing these skills early is vital for children to view education with a positive outlook. Unfortunately, many students struggle with this facet of early numeracy.

This study focuses on how one ‘intensive’ kindergarten student’s number recognition skills were affected by individualized interventions. It explores where the student struggled …

Purification Of Lactate Dehydrogenase, Irene J. Wilson

Scholarly and Creative Works Conference (2015 - 2021)

Lactate dehydrogenase (LDH), sometimes referred to as lactic acid dehydrogenase, is an enzyme that is found in the cytoplasm of almost all living cells. It converts lactate and NAD+ (nicotinamide adenine dinucleotide) to pyruvate and NADH (nicotinamide adenine dinucleotide hydrogen), and it can also catalyze the reverse reaction. Heart muscle is highly oxygenated at all times; therefore, LDH catalyzes the reaction in the direction to form NADH and pyruvate, which is used in the Citric Acid Cycle to make energy for the cell via aerobic cellular respiration. When little or no oxygen (O2) is available to the cell, such as …

The Ethics Of Environmentalism For The Individual Consumer, Molly Collins

Jepson School of Leadership Studies Research Symposium

Climate change harms the health of the environment and the well-being of humans. It is the poor choices of individual consumers that contribute to climate change conditions. I argue that it is immoral to cause harm to others, thus climate change is an ethical dilemma for individual consumers. Enforcement of climate change policies are therefore justified, as individuals who cause harm through consumer behavior are liable to punishment. I begin with a pluralistic discussion of harm, before discussing the duties of individuals to make choices that will mitigate the current harms of climate change and the wrong moral assumptions that …

Chute Cutoffs And Alluvial Point Bar Morphodynamics: How Rivers Move Over Time, Caelan Simeone

University of Montana Conference on Undergraduate Research (UMCUR)

The reach of the Clark Fork River just west of Missoula is quite dynamic, and due to erosion and deposition of sediments can shift quite rapidly during floods. During spring runoff in 2012 the main channel of the Clark Fork River about 1.3 miles west of the Reserve Street Bridge scoured through the point bar (a type of gravel or sand bar) on the inside of a meander bend and created a new channel. This event is called a chute cutoff and is one of two main ways that rivers cut through their banks to create new channels. Understanding of …

Nano-Structured Materials For Energy Storage Applications, Dongxue Zhao

Dissertations

Hydrogen is a non-polluting and efficient energy carrier. One barrier to utilizing hydrogen is a reliable storage method. NaAlH4 is the prototypical example of a complex metal hydride with high hydrogen storage capacities (~ 5.5 wt.%) and acceptable reaction temperatures of around 100 ℃ when using catalyst. On decomposition of these complex hydrides, such as NaAlH4, one is left with monohydride NaH. The kinetics of diffusion in the monohydrides is important because reversibility hinges on mass transport and the formation of [AlH4] - anions that must structurally coordinate with the alkali metal cation on hydrogen absorption. The NaH/NaOH system of …

Does Predation Influence The Seasonal And Diel Timing Of Moose Calving In Central Ontario, Canada?, Brent R. Patterson, Kenneth J. Mills, Kevin R. Middel, John F. Benson, Martyn E. Obbard

School of Natural Resources: Faculty Publications

Birth synchrony is well documented among ungulates and is hypothesised to maximize neonate survival, either by minimizing the risk of predation through predator swamping or by synchronising birthing with increased seasonal food availability. We used encapsulated vaginal implant transmitters to locate and capture neonatal moose calves and document the seasonal and diel timing of parturition in two adjacent study areas with different predation pressure in central Ontario, Canada. We tested the hypothesis that predation promotes earlier and more synchronous birth of moose calves. Across both areas, proportionately more births occurred during the afternoon and fewer than expected occurred overnight. Mean …

Power And Sample Size Calculations For Interval-Censored Survival Analysis, Hae-Young Kim, John M. Williamson, Hung-Mo Lin

NYMC Faculty Publications

We propose a method for calculating power and sample size for studies involving interval-censored failure time data that only involves standard software required for fitting the appropriate parametric survival model. We use the framework of a longitudinal study where patients are assessed periodically for a response and the only resultant information available to the investigators is the failure window: the time between the last negative and first positive test results. The survival model is fit to an expanded data set using easily computed weights. We illustrate with a Weibull survival model and a two-group comparison. The investigator can specify a …

Dynamical Spacetime Symmetry, Benjamin Lovelady, James Thomas Wheeler

Physics Student Research

According to the Coleman-Mandula theorem, any gauge theory of gravity combined with an internal symmetry based on a Lie group must take the form of a direct product in order to be consistent with basic assumptions of quantum field theory. However, we show that an alternative gauging of a simple group can lead dynamically to a spacetime with compact internal symmetry. The biconformal gauging of the conformal symmetry of n-dimensional Euclidean space doubles the dimension to give a symplectic manifold. Examining one of the Lagrangian submanifolds in the flat case, we find that in addition to the expected SO(n) connection …

Building Exemplary Teaching Practices: Following The Paths Of New Science Teachers, Elizabeth B. Lewis, Ana Rivero, Aaron A. Musson, Jia Lu, Lyrica Lucas

Department of Teaching, Learning, and Teacher Education: Presentations

There are few comprehensive studies of beginning science teachers that describe enacted teaching practices in terms of inquiry-based instruction, classroom discourse, assessment, and curricular choices, and explore how these factors interact with teaching self-efficacy. We conducted a 3-year, longitudinal study of four cohorts of master’s level science teacher education program graduates. We coded and analyzed 319 science lessons of new teachers from student teaching to third year post-program to describe teachers’ enacted practices and gathered annual teaching self-efficacy reports to examine teachers’ beliefs. Our analysis resulted in key findings relevant to future programmatic improvements. First, when we reviewed specific inquiry-based …

Basal Characteristics Of The Main Sticky Spot On The Ice Plain Of Whillans Ice Stream, Antarctica, Tarun Luthra, Sridhar Anandakrishnan, J. Paul Winberry, Richard B. Alley, Nicholas Holschuh

Geological Sciences Faculty Scholarship

Understanding the processes that affect streaming ice flow and the mass balance of glaciers and ice sheets requires sound knowledge of their subglacial environments. Previous studies have shown that an extensive deformable subglacial sediment layer favors fast ice-stream flow. However, areas of high basal drag, termed sticky spots, are of particular interest because they inhibit the fast flow of the overriding ice. The stick-slip behavior of Whillans Ice Stream (WIS) is perhaps the most conspicuous manifestation of a subglacial sticky spot. We present new ice-thickness and seismic-reflection measurements collected over the main sticky spot in the ice plain of WIS, …

Modeling Crash Delays In A Route Choice Behavior Model For Two Way Road Networks, Mohammad Sadra Sharifi, Hesam Shabaniverki

Civil and Environmental Engineering Student Research

Distributing demand in a transportation network is based on route choice behavior models. Generally, it is assumed that drivers use routes with minimum time. In real world, drivers may consider many factors other than travel times in congested networks especially in metropolitan or two way congested transportation networks. Travel safety is a factor that one may consider in his/her trip route choice. The main objective of this paper was to investigate influence of safety factors such as crash delays on drivers’ route choice behaviors. Parameters that can cause to crash occurrences were specified and their impacts were modeled at macroscopic …

Reef Fish Spatial Distribution And Benthic Habitat Associations On The Southeast Florida Reef Tract, Dana Fisco

HCNSO Student Theses and Dissertations

The Florida Reef Tract (FRT) extends from the tropical Caribbean up the southeast coast of Florida into a temperate environment where tropical reef assemblages diminish with increasing latitude. This study used data from a three-year comprehensive fishery-independent survey to quantify reef fish spatial distribution along the Southeast FRT and define where the assemblage shifts from tropical to temperate. A total of 1,676 reef fish visual census samples were conducted to assess the populations on a stratified-random selection of sites of marine hardbottom habitats between the Miami River and St. Lucie inlet. Multivariate analyses were used to investigate differences in assemblages …
