Testing The Efficiency Of The Nfl Betting Market, Ryan Earl Oswald

Honors Program Theses

This paper seeks to investigate the NFL betting market, using statistical and economic tests to challenge the Efficient Market Hypothesis’ claim that it is efficient and no strategy can be expected to make a profit. Specifically, this paper studies the spread, over-under, and money line markets to see if each is efficient on their own and as a collective. In looking to see how these lines can influence the outcomes of each other, this paper finds a number of strategies that were profitable over the timeframe of the data. This shows that the NFL betting market was not completely efficient …

Chromatography-Mass Spectroscopy Analysis Of Native American Pottery For Maple Syrup Residues, Alexis Wirtz

Honors Program Theses

The research conducted regards whether or not Native Americans understood how to create maple syrup before the influence of Europeans. The analytical technique that was used is gas chromatography-mass spectrometry (GC-MS). This technique assisted in understanding what organic residues resided within the pottery and what those organic residues tell us about Native American history. An analysis of organic residues was performed on the following types of pottery: proof of concept pottery, weathered pottery (an analog of the proof of concept), and Native American pottery. The residues used in analysis were obtained through the usage of different solvent systems - Acetone: …

Using Sentiment Analysis To Find The Public's Opinion On Iowa's Three State Schools, Alexa Ryan Bullock

Honors Program Theses

The purpose of this project was to create my own sentiment analysis that would allow me to analyze reviews of the three Iowa state schools: University of Iowa, Iowa State, and University of Northern Iowa, and organize them in a way that showed the strong and weak points of each university. I accomplished this by researching how sentiment analysis works, applying that to the construction of my own sentiment analysis, and then using it on reviews about these three schools. The goal of this project was to give my audience a greater understanding of how sentiment analysis works by creating …

Creating Synthetic Analogs Of Fluorescent Speleothems In Wind Cave As An Astrobiological Model Cave, Teresa Feldman

Honors Program Theses

The wind cave system represents a unique environment on Earth where the direct interplay of organic chemistry on the surface can possibly be traced to extremophiles living hundreds of meters below the surface. In many cases, minerals and organics from the surface become trapped in calcite formations creating fluorescent minerals. To understand the environment giving rise to the fluorescent minerals in Wind Cave, laboratory analogs of the calcite crystals found within the Wind Cave National Park cavern were synthesized and analyzed using SEM and fluorescence spectroscopy. This data was compared to the fluorescence and XRF data collected from speleothems in …

The Idolization Of Ada Lovelace And Its Necessity, Autumn Lauen

Honors Program Theses

Ada Lovelace is a recognizable name in the field of computer science, but few people know and truly understand why. It is common knowledge that Ada Lovelace is known as the world’s first computer programmer. A simple Google search would also show that her contributions occurred in the mid-1800s. This is where any logical person may become confused and rightfully inquire how a person in the Victorian era has become so closely associated with modern computer science. The answer to that question is exactly as complicated and disputed as expected.

Ada Lovelace’s fame stems from her work with Charles Babbage …

Transition metal dichalcogenides have gained increasing interest due to properties that make them highly attractive for fundamental studies of novel physical phenomena and for applications ranging from nanoelectronics and nanophotonics to sensing and actuation at the nanoscale.^[1] The material described in this work is composed of layers of tantalum sulfide between which manganese was deposited. The number of manganese atoms per tantalum atom is called the concentration, x. In the research that was conducted for this thesis, the Griffiths Phase of crystalline bulk Mn_0.23TaS₂ and the 3-dimensional Ising model was investigated.

An Exploration In Ramsey Theory, Jake Weber

Dissertations and Theses @ UNI

We present several introductory results in the realm of Ramsey Theory, a subfield of Combinatorics and Graph Theory. The proofs in this thesis revolve around identifying substructure amidst chaos. After showing the existence of Ramsey numbers of two types, we exhibit how these two numbers are related. Shifting our focus to one of the Ramsey number types, we provide an argument that establishes the exact Ramsey number for h(k, 3) for k ≥ 3; this result is the highlight of this thesis. We conclude with facts that begin to establish lower bounds on these types of Ramsey …

Life And Death: Quantifying The Risk Of Heart Disease With Machine Learning, Jack Scott Glienke

Honors Program Theses

Coronary heart disease has long been a key area of focus in the discussion of public health. As such, numerous studies have been conducted throughout history with the sole intention of identifying risk factors leading to the onset of cardiovascular conditions. A plethora of statistical procedures can be used to identify an individual’s risk of developing heart disease, yet regression models tend to be the default tool used by researchers. Using the data obtained from the most influential cardiovascular study to date, the Framingham Heart Study, this analysis uses machine learning techniques to generate and test the predictive power of …

An Alternative Approach To Malware Research, Christopher James May

Honors Program Theses

Current antivirus programs have design flaws that allow malware to bypass detection. Despite this, malicious parties are usually the ones to find and exploit these flaws before they can be fixed. Therefore, a more proactive approach to malware research should become the new standard. To that end, a new programming language will be designed and created that sheds light on a couple of design flaws in current antivirus models. Fundamentally, antivirus programs have trouble detecting interpreted languages. In addition, it is suspected that antivirus programs are unable to detect an unknown programming language that is injected into another file thus …

On The Zeta Kirchhoff Index Of Several Graph Transformations, Danny Cheuk

Dissertations and Theses @ UNI

In this paper, we first derived the Ihara zeta function, complexity and zeta Kirchhoff index of the k-th semitotal point graph (of regular graphs), a construction by Cui and Hou [5], where we create triangles for every edge in the original graph. Then, we extend the construction to the creation of equilaterals and polygons.

We also derived the zeta Kirchhoff indices for numerous graph transformations on regular graphs, and some selected families of graphs.

At the end, a data summary is provided for enumeration computed on simple connected md2 graphs up to degree 10.

Analysis Of A Paleoglacier Reconstruction Model For Valley Glaciers Of The Wind River Range, Wyoming, Taylor Rae Garton

Dissertations and Theses @ UNI

Various approaches, ranging from in-field morphological reconstructions to more technology-based modelling practices allow us to reconstruct and understand the long-term geomorphic evolution of landscapes. The study of paleo-environments by reconstruction can also give us profound insight into paleo-climate. A new model, GlaRe (Glacial Reconstruction), has been introduced into the alpine glacier modeling community to facilitate glacier reconstruction. In this research the mathematical equations representing the basal shear stress parameter are tested to determine the applicability of the GlaRe model to alpine glaciers in the American West. Known ages and extents of past glacier advances were used to test the reconstructions …

Code Readability: A Proposal On The Effects Of Psychology And Comprehension In Software Development And Maintenance, Ethan Brian Sankey

Honors Program Theses

Because of the diversity and complexity of the hundreds of coding languages out there, code readability has become more and more of an issue as the years have passed and as the popularity of technology that required built-in computers has increased. With so many different formats, styles, and restrictions on each language, even a developer with experience in only a few common languages may have trouble remembering which language allows for certain indentation, which language requires variable instantiation, which language requires return statements at the end of functions. While I can appreciate the diversity and efficiency that having many different …

Analysis Of Ambient Particulate Concentration Near A Coal Storage Pile, Jennifer Wittenburg

Dissertations and Theses @ UNI

Fugitive dust sources such as aggregate storage piles contribute significantly to the total suspended particulate levels in the ambient air. Particulate levels are monitored and regulated by the Environmental Protection Agency to protect public health and welfare. This study monitored particulate concentrations in the ambient air near a coal storage pile. Air samplers and weather stations were placed at two locations, one to the north of the pile and one to the south of the pile, and were used to collect particulate and weather related data.

The data were analyzed to determine the origin of the particulate and to identify …

Van Der Waals Interactions In Ultrafine Nanocellulose Aerogels, Byron John Fritch

Honors Program Theses

The purpose of this study was to establish methods of synthesizing various compositions of nanocellulose aerogels using a top-down ultrasonication synthesis approach. Quantifying the effect composition has on physical properties was also be of interest due to the lack of scientific literature over this material. Microscopic techniques and physical experiments were used to determine how the internal structure of the aerogel material varies with composition and how the internal structure effects the physical properties. The main driving factor behind this study was that not much current scientific literature can be found about how the ultrasonic process effects the nanocellulose aerogels. …

Analysis Of Vibrational Modes Of Chemically Modified Tone Wood, Madison Flesch

Honors Program Theses

It is generally accepted that every violin has different tone quality in terms of intonation and the depth of the harmonics produced. The best violins are made by experienced luthiers that craft each with precision to produce the best possible tonal quality. The quality of the finished violin is dependent upon both the specific shape and the vibrational response of the wood used in its construction. Because the hard wood used in violin construction is inhomogeneous, the composition and structure of material used is critical to the final product.¹ Luthiers would initially rely on their experience to feel the …

Money Matters: An Analysis Of Campaign Finance In United States House Of Representatives Elections, 2010-2016, Destiny Leitz

Honors Program Theses

Money in politics is the single largest threat to the democratic system in the United States. It influences everything in politics, from the candidates to the issues debated. Every American knows that running for office requires large amounts of funding, and being elected requires even more. People worry that only the wealthiest voices are being heard; of course, candidates who depend on money from wealthy donors for campaign strength would never support unfavorable policies for their donors. Clearly, money in politics threatens the core democratic principles upon which America was founded. However, few people discuss whether the money really makes …

Resale Value Of Individual Sets Of Magic The Gathering, Nichole Bolas Mlodzik

Honors Program Theses

Magic: the Gathering is a strategy-based fantasy card game developed by Richard Garfield in 1993. The appeal of playing the game is found in using cardboard printed cards to cast spells to achieve a victory over one or more opponents. This thesis will provide an analysis of six MTG sets, calculating the average value of one pack of fourteen cards. The relationships between the average resale value for each set will be evaluated using statistical graphical analysis. Conclusions will be drawn regarding the average resale value of a pack of fourteen cards in each of six sets

Honors Program Theses

The purpose of this research was to develop a new method of analyzing organic residues left on Native American pottery using linear Raman spectroscopy. Native American pottery was replicated using terra cotta and maple syrup was boiled in each of the pots using boiling stones. The pottery shards were then analyzed using Raman spectroscopy. Shards of pottery with maple syrup residue were compared to the standards and the syrup residue was not only detected, but also matched to compounds in the instrument library. Typically, the study of Native American pottery has been done in a variety of different ways, many …

Exploration Of Counter Examples Of Balanced Sets, Jake Allen Weber

Honors Program Theses

Mathematicians are often intrigued with patterns, many times finding themselves looking for pieces of structure within a data set. This research project is no different in that we have explored our vast data set for substructure.

Our goal is to identify the following: how many data points are necessary to guarantee our set has a balanced set/substructure? Naturally rephrasing the previous question, we also ask ourselves what is the largest set that does not have a balanced subset/substructure? This alternate phrasing set us down our current path. We focused on the largest sets with no balanced substructure and what they …

An Analysis Of Equity-Linked Insurance Pricing, Clara C. Ortgies

Honors Program Theses

This comprehensive study of equity-linked insurance options will explore the pricing of certificates of deposit and life insurance options using a present value method. With this study, I will be able to construct and price various equity-linked insurance products, with a focus on life insurance, that insurance companies could then sell to prospective customers. I will use concepts and formulas based in actuarial math, probability theory, and financial engineering in order to construct, price, and analyze new equity-linked insurance products. The fundamental methodology I will use involves applying pricing theory based on the expected value of the insurance payoff present …

Magnetic Behavior Of Bulk And Nanostructured Mnxtas2, Lucas Paul Beving

Honors Program Theses

At its base, material science research aims to categorize specific materials by their various attributes, such as structure, integrity, electronic properties, magnetic properties, and others. By categorizing materials in this way, it becomes easier to generalize the application of a specific material to those within a broader category. The interest in materials that exhibit useful characteristics at small scales derives directly from the technology industry’s need for smaller and smaller devices. Two-dimensional materials are of great interest for this reason.

Two-dimensional materials are comprised of many single layers, or planes, stacked together to create a crystal. Each layer may be …

Investigating The Role Of The Written Curriculum On Lesson Planning For First-Year Elementary Mathematics Teachers, Anna Kron

Honors Program Theses

While studies have previously explored aspects of lesson planning from the perspective of experienced teachers, there is a lack of research investigating how this process is different for brand new educators. The researcher, a preservice elementary teacher studying at the University of Northern Iowa, wanted to learn more about the available resources and how she would utilize them when planning for mathematics instruction in her first elementary classroom. At the completion of this project, the researcher hoped to have a better understanding of the process first-year elementary teachers experience when transforming written textbook materials into a mathematics lesson plan. The …

A Survey Of Butterfly Diagrams For Knots And Links, Mark Ronnenberg

Dissertations and Theses @ UNI

A “butterfly diagram” is a representation of a knot as a kind of graph on the sphere. This generalization of Thurston’s construction of the Borromean rings was introduced by Hilden, Montesinos, Tejada, and Toro to study the bridge number of knots. In this paper, we study various properties of butterfly diagrams for knots and links. We prove basic some combinatorial results about butterflies and explore properties of butterflies for classes of links, especially torus links. The Wirtinger presentation for the knot group will be adapted to butterfly diagrams, and we translate the Reidemeister moves for knot diagrams into so-called “butterfly …

The Programmatic Manipulation Of Planar Diagram Codes To Find An Upper Bound On The Bridge Index Of Prime Knots, Genevieve R. Johnson

Dissertations and Theses @ UNI

The “bridge index” of a knot is the least number of maximal overpasses taken over all diagrams of the knot. A naïve method to determine the bridge index of a knot is to perform Reidemeister moves on diagrams of the knot, and this method quickly becomes tedious to implement by hand. In this paper, we introduce a sequence of Reidemeister moves which we call a “drag the underpass” move and prove how planar diagram codes change as Reidemeister moves are performed. We then use these results to programatically perform Reidemeister moves using Python 2.7 to calculate an upper bound on …

Properties Of Left-Separated Spaces And Their Unions, Eric Scheidecker

Dissertations and Theses @ UNI

Left-separated spaces are topological spaces which can be well ordered such that every initial segment is closed. In this paper, we examine what topological properties imply left-separation, and under what circumstances left-separation is preserved by unions. We also introduce several known theorems regarding elementary submodels as they are one of the primary tools that we use. We prove that for a topological space X;

1. If X has a point-countable base, then X is left-separated if and only if X has closed intersection with any elementary submodel M such that X ∈ M.

2. If every elementary submodel …

Formation Of Titan Aerosol From Co And Ch4, Tate Christensen

Honors Program Theses

In 1952 Stanley Miller and Harold Urey conducted an experiment that would simulate the conditions of early earth (Miller, 1953). The purpose was to observe the chemical origins of life, and the conclusion supported an earlier theory that such conditions favor the synthesis of more complex organic compounds from simpler inorganic molecules. The research conducted in Dr. Sebree’s lab is an extension of these early findings. It is believed that early Earth was composed mostly of nitrogen, carbon monoxide, carbon dioxide and methane as opposed to our atmosphere of nitrogen and oxygen today.

Saturn’s largest moon, Titan, has qualities relatively …

Three Men In The Wilderness: Ideas And Concepts Of Nature During The Progressive Era With Theodore Roosevelt, Gifford Pinchot And John Muir, Jeffrey A. Duke

Dissertations and Theses @ UNI

When I began this research in the summer of 2014, I endeavored to find out how Americans comprehended nature in the Progressive Era. By the Progressive Era the historian Frederick Jackson Turner declared the frontier to be closed. This notion that no wide open spaces remained to be conquered altered the American people’s attitude towards nature. The perspectives of three men who were at the forefront of environmental policy illustrate how America’s understanding of nature had changed. These three men were twenty-sixth President Theodore Roosevelt, professional forester Gifford Pinchot and naturalist John Muir. Describing the similarities and differences in these …

Statistical Modeling Of Earthquake Damage, Allison Nicole Waters

Honors Program Theses

The purpose of this study was to build a statistical model of the economic damage that arises from earthquakes in order to better predict losses from future earthquakes. Though earthquakes are essentially a random event and cannot be fully anticipated, analyzing historical data and creating a statistical model can provide researchers with a more accurate estimate of future losses. The data set from which this model was built incorporated earthquakes occurring worldwide from 1915-2015 in which the total damage was recorded. The final model was a multiple linear regression model explaining total damage resulting from an earthquake through four independent …

Magnetic Properties Of Polymeric Framework Materials With Cobalt, Cassara Higgins

Honors Program Theses

Single molecule magnets (SMM) are a new class of materials that have not been well studied. Metal-organic frameworks (MOFs) created with cobalt(II) metal centers have unpaired 3d electrons, which gives the frameworks interesting magnetic properties. Cobalt(II) nitrate centers can be linked together by varying numbers of 4,4´-bipyridine (bpy) ligands to create six different framework structures: four-coordinate 1D chain, five-coordinate 1D ladder, 2D bilayer, and 3D brick wall, and six-coordinate 2D square grid and 2D rhombic grid. The effects of framework structure and Co(II)-Co(II) distance on Weiss temperatures and μeff were investigated. By understanding which parameters of a framework has the …

Some Convergence Properties Of Minkowski Functionals Given By Polytopes, Jesse Moeller

Dissertations and Theses @ UNI

In this work we investigate the behavior of the Minkowski Functionals admitted by a sequence of sets which converge to the unit ball ‘from the inside’. We begin in R 2 and use this example to build intuition as we extend to the more general R n case. We prove, in the penultimate chapter, that convergence ‘from the inside’ in this setting is equivalent to two other characterizations of the convergence: a geometric characterization which has to do with the sizes of the faces of each polytope in the sequence converging to zero, and the convergence of the Minkowski functionals …
