Introductory Calculus: Through The Lenses Of Covariation And Approximation, Caleb Huber

Graduate Student Portfolios, Papers, and Capstone Projects

Over the course of a year, I investigated reformative approaches to the teaching of calculus. My research revealed the substantial findings of two educators, Michael Oehrtman and Pat Thompson, and inspired me to design a course based upon two key ideas, covariation and approximation metaphors. Over a period of six weeks, I taught a course tailored around these ideas and documented student responses to both classroom activities and quizzes. Responses were organized intonarratives, covariation, rates of change, limits, and delta notation. Covariation with respect to rates of change was found to be incredibly complex, and students would often see it ...

Beginning Algebra Made Useful, Charlene E. Beckmann May 2020

Beginning Algebra Made Useful, Charlene E. Beckmann

Open Textbooks

Beginning Algebra Made Useful addresses the needs of learners to make sense of algebra by quantifying and generalizing everyday occurrences such as commuting to work, buying gas or pizza, and determining the better deal. It requires learners to actively engage with algebraic concepts through physical and thought experiments in ways that help them connect ideas, representations, and contexts, and solve problems that arise in their daily lives. The text helps learners grow their brains and develop growth mindsets as they learn algebra conceptually. Problem sets continue the process, extending work begun in each lesson, applying new understandings to new contexts ...

Congressional Redistricting, C. David Robshaw May 2020

Congressional Redistricting, C. David Robshaw

Zyzzogeton Posters

To identify when gerrymandering occurs, one can study compactness measures of districts. After determining that some measures of compactness alone are insufficient to identify fair or biased district boundaries, this study's investigation continues by focusing on wasted votes. Using wasted votes, a procedure is developed and coded in R that takes a given congressional district map and alters it to provide a redistricting of desired fair or partisan results.

Charged Particle Identification Using Calorimetry And Tracking At The Belle Ii Experiment, Joseph T. Nunziata, Atanu Pathak, Swagato Banerjee Apr 2020

Charged Particle Identification Using Calorimetry And Tracking At The Belle Ii Experiment, Joseph T. Nunziata, Atanu Pathak, Swagato Banerjee

Particle identification (PID) is a critical procedure carried out in high energy physics experiments in search of new physics. When particles of matter (i.e., an electron) and antimatter (i.e., a positron) collide, new types of particles may form given certain conditions. Such particles may be classified as hadrons--which feel the strong nuclear force--and leptons--which do not. Identifying particles at the Belle II experiment is done by combining the measurement of energy deposited in the calorimeter with the measurement of track momentum in the tracker. In a tau lepton ($\tau$) decay sample, particles such as electrons, muons, and pions ...

Size-Controlled Synthesis Of Nickel Nanoparticles Enclosed In Carbon Nanocages, Felicity Peebles, Grigorii Rudakov Apr 2020

Size-Controlled Synthesis Of Nickel Nanoparticles Enclosed In Carbon Nanocages, Felicity Peebles, Grigorii Rudakov

We have demonstrated a simple, scalable, and tunable method of obtaining densely packed Ni Nanoparticles encapsulated in Carbon Nanocages (Ni@CNCs). Using a facile method, it was shown that via a simple annealing process of precursor based on nickel acetate and citric acid, Ni@CNCs with sizes varying from 5 to 20 nm can be synthesized by changing the heating ramp rate during the synthesis from 25 to 53 °C/min. The final temperature of 600 °C was held for 10 min, and was the same for all the samples. X-Ray Diffraction (XRD) multiple peaks analysis was performed to show ...

Infectious Disease Mortality Prediction, Kazi Tanvir Hasan Apr 2020

Infectious Disease Mortality Prediction, Kazi Tanvir Hasan

Mathematics

When mortality statistics are reported for infectious diseases, they commonly reflect the ratio for the entire population impacted from it. This causes an underestimation since the frail members of the population are impacted at a higher rate. With the remaining healthy members, the mortality rate becomes skewed. With this project, we study predicting mortality under varying frailty conditions to account for the hidden heterogeneity's impact on the parameter estimates.

The Belknap Campus And Metro Louisville Urban Heat Island Effect: Air And Ground Surface Temperature Analysis, Kenyetta Johnson

Numerous studies show that urban morphologies and land covers generate excess heat emissions and retain heat relative to surrounding rural areas, known as the Urban Heat Island (UHI) effect. Urban fabrics paved by concretes and asphalts absorbs solar radiation during solar peak then radiates heat after sundown. This study investigates temperature distribution data related to the UHI effect on the Belknap campus at the University of Louisville, which represents a small aerial sample of the Louisville metropolitan UHI effect. The objective of this study is to measure the reflectivity of ground surfaces and air temperatures on the Belknap campus during ...

Examining The Role Of Environmental Nonprofits In Shoreline Management For Coastal Resilience In Virginia, Taiwo Oguntuyo, Ogechukwu Agim, Ren-Neasha Blake, Juita-Elena Wie Yusuf, Marina Saitgalina, Michelle Covi Apr 2020

Examining The Role Of Environmental Nonprofits In Shoreline Management For Coastal Resilience In Virginia, Taiwo Oguntuyo, Ogechukwu Agim, Ren-Neasha Blake, Juita-Elena Wie Yusuf, Marina Saitgalina, Michelle Covi

Environmental Nonprofits emerged over the years to attend to the environmental needs of communities and individuals, as well as address environmental issues that concern the public. These issues are usually those that have been neglected, given insufficient attention, or cannot be singularly handled by the government. In advocating for coastal resilience, environmental nonprofits have been identified in the literature as actors with critical roles in addressing coastal issues such as sea-level rise, flooding and shoreline management. In recent times, shoreline management has emerged as one of the foremost areas of focus expedient for the achievement of coastal resilience, and the ...

Npgreat: Hybrid Assembly Of Human Subtelomeres With The Use Of Nanopore And Linked-Read Datasets, Eleni Adam, Desh Ranjan, Harold Riethman Apr 2020

Npgreat: Hybrid Assembly Of Human Subtelomeres With The Use Of Nanopore And Linked-Read Datasets, Eleni Adam, Desh Ranjan, Harold Riethman

College of Sciences Posters

The telomeres are vitally important regions that are located at the tips of the chromosomes. Their dysfunction, caused by length shortening can lead to senescent cells, which in turn cause age-related diseases, including cancer. The subtelomeres, located next to the telomeres, possess the critical role of regulating the adjacent telomere lengths. Even after many years of research, human subtelomeres have proven to be very hard to assemble due to their morphology. In order to overcome these problems, the hybrid assembly method we develop utilizes two of the latest available types of data, which complement each other: Linked-Reads and ultralong Nanopore ...

D-Vine Copula Model For Dependent Binary Data, Huihui Lin, N. Rao Chaganty Apr 2020

D-Vine Copula Model For Dependent Binary Data, Huihui Lin, N. Rao Chaganty

College of Sciences Posters

High-dimensional dependent binary data are prevalent in a wide range of scientific disciplines. A popular method for analyzing such data is the Multivariate Probit (MP) model. But the MP model sometimes fails even within a feasible range of binary correlations, because the underlying correlation matrix of the latent variables may not be positive definite. In this research, we proposed pair copula models, assuming the dependence between the binary variables is first order autoregressive (AR(1))or equicorrelated structure. Also, when Archimediean copula is used, most paper converted Kendall Tau to corresponding copula parameter, there is no explicit function of Pearson ...

Sulfur Dioxide From The Atmospheric Chemistry Experiment Satellite, Doug Cameron

College of Sciences Posters

The version 4.0 dataset from the Atmospheric Chemistry Experiment – Fourier Transform Spectrometer (ACE-FTS) on SCISAT, released in March of 2019, has sulfur dioxide (SO2) volume mixing ratio (VMR) profiles as a routine data product. From this dataset, global SO2 distributions between the altitudes of 10.5 km and 23.5 km are analyzed. The global distribution of all SO2 VMR data by altitude is broken down into 30° and 5° latitude zones. Seasonality of the global SO2 distribution is explored. Volcanic SO2 plumes are isolated in the dataset and compared with extinction data from ...

Cylindrical Similarity Measurement For Helices In Medium-Resolution Cryo-Electron Microscopy Density Maps, Salim Sazzed, Peter Scheible, Maytha Alshammari, Willy Wriggers, Jing He

College of Sciences Posters

Cryo-electron microscopy (cryo-EM) density maps at medium resolution (5-10 Å) reveal secondary structural features such as α-helices and β-sheets, but they lack the side chains details that would enable a direct structure determination. Among the more than 800 entries in the Electron Microscopy Data Bank (EMDB) of medium-resolution density maps that are associated with atomic models, a wide variety of similarities can be observed between maps and models. To validate such atomic models and to classify structural features, a local similarity criterion, the F1 score, is proposed and evaluated in this study. The F1 score is theoretically normalized to a ...

Measuring Nomophobia And Exploration Of Consequences And Comorbidities, Sarah Marie Fryman, William L. Romine Apr 2020

Measuring Nomophobia And Exploration Of Consequences And Comorbidities, Sarah Marie Fryman, William L. Romine

Symposium of Student Research, Scholarship, and Creative Activities Materials

Excessive use of smartphones has coined the term “Nomophobia”, or fear of not being able to use your smartphone. For many, these devices have become an extension of ourselves, which raises hesitation on whether or not society has become addicted to smartphones. Specific diagnostic criteria for smartphone addiction have yet to be settled, and even appropriate to use the word “addiction” when describing excessive usage of smartphones is controversial.

We therefore explore utilize current measures to explore the symptoms of nomophobia and their hierarchy, as well as comorbidities including social anxiety, self-esteem, distracted driving and sleep quality. A total of ...

Multi-Label Model For Toxicity Prediction, Xiu Huan Yap, Michael L. Raymer Apr 2020

Multi-Label Model For Toxicity Prediction, Xiu Huan Yap, Michael L. Raymer

Symposium of Student Research, Scholarship, and Creative Activities Materials

Most computational predictive models are specifically trained for a single toxicity endpoint. Since more than 1300 toxicity assays have been reported in the TOXCAST dashboard, achieving high coverage over this growing number of toxicity endpoints remains challenging. Furthermore, single-endpoint models lack the ability to learn dependencies between endpoints, such as those targeting similar biological pathways, which may be used to boost model performance. In this study, we characterize the performance of 3 multi-label classification (MLC) models, namely Classifier Chains (CC), Label Powersets (LP) and Stacking (SBR), on Tox21 challenge data. These MLC models employ the Problem Transformation approach, which is ...
