Conformal Geometry Of Polygons, Michael Albert

WWU Honors College Senior Projects

Conformal maps are functions from subsets of the complex plane to the complex plane that locally preserve angles. Our goal is to understand conformal maps that pass to and from polygonal domains. In order to do so, we derive some of the basic theory of harmonic functions on simply connected domains. In particular, our goal with the first few sections is to prove the Schwarz Reflection principle. Using this, as well as other tools from complex analysis, we give an in-depth explanation of Tao’s proof of the Schwarz-Christoffel formula. This is a differential equation that allows one to compute a …

Quick Guide To Plant Families Of Western Washington, Maggie Hayward, John D. Tuxill, James M. Helfield

WWU Honors College Senior Projects

This guide is an expanded version of a booklet designed to help students identify native plants in western Washington. It has been expanded to include invasive and ruderal taxa commonly found in riparian areas. The purpose of this guide is to provide practical help for identifying plant families, and to facilitate a basic understanding of plant morphology. By observing morphological characteristics such as leaf arrangement and structure, the user can narrow an unidentified species down to the family level. Because this book does not go to the species level, it is meant to be used as a companion to other …

Do Men Matter? In Statistics, Probably, Michael Kelly

WWU Honors College Senior Projects

In statistical genetics, there are several parameters of a dataset which a researcher might, but which are difficult to estimate in practice. In this paper, we will be focusing on allele frequencies, null alleles, inbreeding coefficients and, to a certain extent, beta values. A common technique for obtaining these values, developed by Amy Anderson and her co-workers, is to jointly estimate all of them using an EM-algorithm and the method of maximum likelihood. Despite this technique being effective in general, it is currently unable to deal with males at X-linked markers. The purpose of this project is to modify the …

Equity In Stem: Utilizing Student Experience To Better Inform Policy And Practice, Natasha Hessami

WWU Honors College Senior Projects

As women and people of color continue to pursue higher education and other advanced degrees, the STEM field consistently lags behind in diverse representation and leadership. There is a critical need to address the structural barriers marginalized groups face to accessing and succeeding in STEM and invest both time and money into innovative student-centered solutions. This project outlines the development of the CSE Student Ambassador program and implementation recommendations, the development and presentation of seminars focused on equity in the Biology and Chemistry departments, and general recommendations for faculty to make classroom and lab spaces more inclusive.

Preliminary Impacts Of Constructed Log Jams On Streambed Topography And Bed Temperature On The South Fork Nooksack River, Sam Kaiser

WWU Honors College Senior Projects

Salmon are an essential part of the culture, ecology and economy of the Pacific Northwest region of North America, but populations of some ecotypes are declining. One specific population, the Puget Sound chinook (Oncorhynchus tshawytscha), is listed as threatened under terms of the U.S. Endangered Species Act (ESA). The decline of this ecotype has implications not only for humans but also for all links of the ecosystem such as the populations of southern resident killer whales (Orcinus orca) which prey predominately on chinook salmon. Major threats to these fish include overharvest and habitat degradation due to …

Deblurring Images, Jamie Mcmullen

WWU Honors College Senior Projects

Let the matrix B be a blurred version of a sharp image represented by the matrix X. Given B, we would like to recover X.

To accomplish this, we construct linear models of the blurring process that produced B from X. The idea is that we could then reverse the blurring to reproduce the original image.

For example, if the blurred image satisfies

B = CXR^T

for some invertible matrices C and R, then we could recover X as

X = C-¹B(R^T)^-1.

However, the blurring model …

The Energy Imbalance Market: Environmental Benefits Of Regional Market Integration In The West, Kristen E. Tarr

WWU Honors College Senior Projects

Compared to other regions of the United States, the Western electric grid is fragmented and balkanized, due to lack of regional market coordination. As the West anticipates the growth of renewable energy, there is an evident need for regional market interconnection. The Energy Imbalance Market (EIM) is the first sub-hourly regional power-trading market in the West, allowing Western utilities to buy and sell electricity across the diverse geographic region (EIM, 2018a). By tapping into the flexibility and diversity of regional production profiles, the EIM reduces the variability and intermittency of renewable power. According to the 2017 quarterly benefits report, from …

Reduced Light Availability Diminishes Mycorrhizal Growth Response Of Invasive Forb, Regina O'Kelley

WWU Honors College Senior Projects

Arbuscular mycorrhizal fungi (AMF) form mycorrhizae, a common, well-studied symbiotic relationship. Controls on the magnitude and direction of plant mycorrhizal growth response (MGR) remain obscured. Specifically, the influence of light availability in the MGR of an invasive forb, spotted knapweed Centaurea stoebe, has not been studied. Greenhouse studies exploring the growth response of knapweed to arbuscular mycorrhizae (AM) often fail to report light intensity levels, which could impact the quality of their data. I conducted a greenhouse experiment studying the MGR in spotted knapweed under shaded and unshaded conditions, designed to approximate light availability in ambient greenhouse and full-sun …

Sehome Hill Arboretum Trail Decommissioning Follow Up, Calvin Heslop

WWU Honors College Senior Projects

Maintaining accessible trail networks for recreation and travel is an important part of management in the Sehome Hill Arboretum in Bellingham Washington. Trails aid in bringing people into the arboretum so they can appreciate and enjoy what it has to offer. Additionally trails serve the purpose of limiting human impact to known and maintained areas. Unofficial “social” trails can be detrimental to both the accessibility and ecological function of the Arboretum. By adding to the existing trail network, these social trails can confuse park visitors as well as decrease the aesthetic value of the arboretum. Additionally, repeated traffic by hikers …

Fish Abundance And Habitat Recommendations Of The Lake Whatcom Tributaries, Ariel Edwards

WWU Honors College Senior Projects

The tributaries of Lake Whatcom, Austin/Beaver, Anderson, Olsen, and Smith Creeks, provide essential habitat for many fish species native to the Pacific Northwest. However, development in the watershed has contributed to habitat alterations and even degradation of habitat quality. In this report, fish abundance and diversity, and habitat quality is compared both temporally, and among different streams. Anderson Creek was found to have the greatest species diversity. Cutthroat trout was the most abundant fish at each stream throughout the study period and was observed at every study site. Restoration recommendations for each stream were aimed at supporting existing native fish …

Nickel Phosphide On Boron-Doped Alumina: New Catalysts For Heteroatom Removal Reactions, Catherine E. Miles

WWU Honors College Senior Projects

The effects of boron addition to an alumina (Al₂O₃) support on the hydrodesulfurization (HDS) properties of nickel phosphide (Ni₂P) catalysts have been investigated. The B-Al₂O₃ supports were prepared by a wetness impregnation method using boric acid (H₃BO₃) to dope the alumina support with 0-7.2 wt% B, yielding a boron oxide (B₂O₃) layer of monolayer thickness on the surface of the Al₂O₃ support. Ni₂P precursors were prepared on the B-Al₂O₃ supports in two ways: 1) impregnation …

Soil Conditions And Arbuscular Mycorrhizal Fungal Spore Abundance And Distribution In Dewatered Reservoir Sediments After Dam Removal, Kari Clausen

WWU Honors College Senior Projects

Many dams in the U.S. are reaching the ends of their lifespans and dam removal as a form of river ecosystem restoration is becoming more prevalent. Revegetation of newly exposed sediments is an important aspect of ecosystem recovery after dam removal. Understanding the soil environment left behind after dam removal is important for understanding revegetation and ecosystem recovery trends. Physical soil properties and soil biota communities help to determine the success of plants colonizing exposed sediments after reservoirs are drained. I investigated soil properties and biota after dam removal by looking at the Elwha Dam Removal in Olympic National Park, …

Summer Climate And Western Spruce Budworm Outbreaks In The Pacific Northwest, Melinda Vickers

WWU Honors College Senior Projects

Western spruce budworm outbreaks occur yearly with devastating effects for forests across Oregon, Washington, and British Columbia. However, as of yet, the relationship between these outbreaks and summer climate is poorly understood. In this study, I compared western spruce budworm outbreak records from Oregon, Washington, and British Columbia with June-August temperature and precipitation records between 1975 and 1995. This research reveals interesting patterns in the correlation between drought conditions and western spruce budworm outbreaks. My results necessitate further study examining the potentially significant relationship between summer drought conditions and western spruce budworm outbreaks.
