Pattern Avoidance, Emma Christensen Jan 2017

Pattern Avoidance, Emma Christensen

All College Thesis Program, 2016-2019

A set partition avoids a pattern if no subdivision of that partition standardizes to the pattern. There exists a bijection between set partitions and restricted growth functions (RGFs) on which Wachs and White defined four statistics of interest to this work. We first characterize the restricted growth functions of several avoidance classes based on partitions of size four, enumerate these avoidance classes, and consider the distribution of the Wachs and White statistics across these avoidance classes. We also investigate the equidistribution of statistics between avoidance classes based on multiple patterns.

Climate Change In Alaskan Native Communities: Lessons Learned In Adaptation And Resilience, Sarah M. Mclarnan Sep 2016

Climate Change In Alaskan Native Communities: Lessons Learned In Adaptation And Resilience, Sarah M. Mclarnan

Forum Lectures

The Environmental Protection Agency (EPA) estimates the average temperature in Alaska has risen by 3°F in the past 60 years, over double the rate of warming in the rest of the nation. Nowhere are the consequences more severe than in rural communities. Rising temperatures have resulted in numerous threatening conditions in Alaskan Native villages such as increased rates of erosion, melting permafrost, flooding, poor air quality, severe storms, and declining access to subsistence resources. These conditions affect not only the health and safety of the community, but also traditional culture and lifestyle. This presentation covers research performed at the EPA …

Impartial Avoidance And Achievement Games For Generating Symmetric And Alternating Groups, Bret J. Benesh, Dana C. Ernst, Nándor Sieben Jul 2016

Impartial Avoidance And Achievement Games For Generating Symmetric And Alternating Groups, Bret J. Benesh, Dana C. Ernst, Nándor Sieben

Mathematics Faculty Publications

Anderson and Harary introduced two impartial games on finite groups. Both games are played by two players who alternately select previously unselected elements of a finite group. The first player who builds a generating set from the jointly-selected elements wins the first game. The first player who cannot select an element without building a generating set loses the second game. We determine the nim-numbers, and therefore the outcomes, of these games for symmetric and alternating groups.

University Outdoor Orientation Programs And Their Distance To Public Land, Brian Koch

Celebrating Scholarship & Creativity Day (2011-2017)

Abstract. Many universities encourage students to get outside as much as possible. Getting outside and participating in outdoor orientation programs has shown to be beneficial for student’s physical and mental health as well as allowing students to participate outdoors to better understand the natural world. This project documents the locations of 4-year universities and their proximity to U.S. public and federal lands. By using a research study that has taken a "census" of various orientation programs at 4-year universities, I can document not only the universities that provide these programs, but also show their distances to lands in which the …

Mapping Study Abroad: The Guatemala Experience, Megan Lundquist Apr 2016

Mapping Study Abroad: The Guatemala Experience, Megan Lundquist

Celebrating Scholarship & Creativity Day (2011-2017)

Abstract. For many students, a study abroad program is the first time they will be travelling and living in a particular area abroad. As students go abroad to a variety of locations, they may need maps to help orient them to their living spaces, where their classes are, culturally important locations, and popular places to gather after school. Using ArcGIS, I mapped important locations based on what the participants in the Guatemala program found important to their study abroad experience. I assigned attributes to the locations so that the user can identify different types of locations like points of interest, …

Monitoring The Alteration And Natural Recovery Of A Monsoon-Dominated Stream System After A Wild Fire Disturbs Its Watershed, Stout Canyon, Utah, Peter D. Christensen, Jennifer E. Hargrave

The Compass: Earth Science Journal of Sigma Gamma Epsilon

The alteration of a stream’s morphology and recovery following a watershed fire is well documented in streams where high flow events occur during spring runoff. However, there are very little data regarding the alteration and natural recovery of streams that have high flow events during the late summer monsoon rains. Stout Canyon, a tributary to the East Fork of the Virgin River, is located approximately 30 miles southeast of Cedar City, Utah, and is a monsoon-dominated stream system whose watershed was burned by the Shingle Fire of 2012. Employees of the Dixie National Forest have monitored Stout Canyon since 2002, …

Hpc Made Easy: Using Docker To Distribute And Test Trilinos, Sean J. Deal Apr 2016

Hpc Made Easy: Using Docker To Distribute And Test Trilinos, Sean J. Deal

All College Thesis Program, 2016-2019

Virtualization is an enticing option for computer science research given its ability to provide repeatable, standardized environments, but traditional virtual machines have too much overhead cost to be practical. Docker, a Linux-based tool for operating-system level virtualization, has been quickly gaining popularity throughout the computer science field by touting a virtualization solution that is easily distributable and more lightweight than virtual machines. This thesis aims to explore if Docker is a viable option for conducting virtualized research by evaluating the results of parallel performance tests using the Trilinos project.

Performance Portable High Performance Conjugate Gradients Benchmark, Zachary Bookey

All College Thesis Program, 2016-2019

The High Performance Conjugate Gradient Benchmark (HPCG) is an international project to create a more appropriate benchmark test for the world's most powerful computers. The current LINPACK benchmark, which is the standard for measuring the performance of the top 500 fastest computers in the world, is moving computers in a direction that is no longer beneficial to many important parallel applications. HPCG is designed to exercise computations and data access patterns more commonly found in applications. The reference version of HPCG exploits only some parallelism available on existing supercomputers and the main focus of this work was to create a …

Impartial Avoidance Games For Generating Finite Groups, Bret J. Benesh, Dana C. Ernst, Nándor Sieben Feb 2016

Impartial Avoidance Games For Generating Finite Groups, Bret J. Benesh, Dana C. Ernst, Nándor Sieben

Mathematics Faculty Publications

We study an impartial avoidance game introduced by Anderson and Harary. The game is played by two players who alternately select previously unselected elements of a finite group. The first player who cannot select an element without making the set of jointly-selected elements into a generating set for the group loses the game. We develop criteria on the maximal subgroups that determine the nim-numbers of these games and use our criteria to study our game for several families of groups, including nilpotent, sporadic, and symmetric groups.

Coal Clinker Site In The Late Cretaceous Blackhawk Formation, Castle Gate, Utah, Usa, Robert L. Eves, Larry E. Davis Jan 2016

Coal Clinker Site In The Late Cretaceous Blackhawk Formation, Castle Gate, Utah, Usa, Robert L. Eves, Larry E. Davis

The Compass: Earth Science Journal of Sigma Gamma Epsilon

When sedimentary host rock is heated as a result of coal seam fires, the host rock is pyro-metamorphosed (high temperature/ low pressure) resulting in the formation of paralava, a low-grade metamorphic rock formed adjacent to coal seams. This paper describes an outcrop locality of clinker (paralava) in the Upper Cretaceous Blackhawk Formation within the Book Cliffs coalfields of central Utah, which formed as the result of a coal seam fire.

Retrival Of Atmospheric Aerosol Size Distributions Using Stochastic Particle Swarm Optimization, Benjamin D. Nault-Maurer Jan 2016

Retrival Of Atmospheric Aerosol Size Distributions Using Stochastic Particle Swarm Optimization, Benjamin D. Nault-Maurer

All College Thesis Program, 2016-2019

A stochastic particle swarm optimization (SPSO) technique’s robustness is studied in regards to atmospheric aerosol size distribution estimations for a bimodal distribution that focuses on Aitken and accumulation mode aerosols. The SPSO method is used to calculate a set of 11 aerosol optical depth (AOD) values based on a size distribution and match them to an inputted set of AOD values. This method is tested using computer generated AOD values with fixed distribution parameters, generated AOD values with varying distribution parameters, two sets of AOD measurements in clear conditions, and one set of AOD values in hazy conditions. The SPSO …

Arithmetic Local Constants For Abelian Varieties With Extra Endomorphisms, Sunil Chetty Jan 2016

Arithmetic Local Constants For Abelian Varieties With Extra Endomorphisms, Sunil Chetty

Mathematics Faculty Publications

This work generalizes the theory of arithmetic local constants, introduced by Mazur and Rubin, to better address abelian varieties with a larger endomorphism ring than ℤ. We then study the growth of the p∞- Selmer rank of our abelian variety, and we address the problem of extending the results of Mazur and Rubin to dihedral towers k ⊂ K ⊂ F in which [F : K] is not a p-power extension.

Pulse And Orbital Periods Of Asas182612, Ariel F. Lusty Jan 2016

Pulse And Orbital Periods Of Asas182612, Ariel F. Lusty

All College Thesis Program, 2016-2019

Physicists S.V. Antipin, K.V. Sokolovsky, and T.I. Ignatieva began observations of the variable star ASAS182612 in 2005, and found it to be the first known eclipsing binary with a type II Cepheid component in our galaxy. A month after Antipin’s publication, the American Association of Variable Star Observers (AAVSO) sent out an alert to campaign for observations of ASAS182612. From July 2007 to November 2015, 147 nights of multi-filter photometric data have been collected for ASAS182162. The pulsation period found was 4.1591 ± 0.0001 days and the orbital period 51.352 ± 0.016 days.

Spectrophotometric Analysis Of Urinary Iodine In 18-22 Year-Old Women In Central Minnesota, Haley Chatelaine Jan 2016

Spectrophotometric Analysis Of Urinary Iodine In 18-22 Year-Old Women In Central Minnesota, Haley Chatelaine

All College Thesis Program, 2016-2019

Iodine is an overlooked but incredibly important micronutrient, especially with regard to early fetus development. The United States does not mandate salt iodization, so widely consumed processed foods are not likely to contain iodized salt, which may potentially put the population at risk for developing iodine deficiencies. Therefore, the purpose of this study is to correspond iodine intake to iodine status and establish effective methods for determining a relationship between the two. Subjects (n=23) completed a food survey and supplied 50mL urine samples to compare an estimated average daily iodine intake based on foods over the course of a week …

A Search For Correlations Between Gamma-Ray Burst Variability And Afterglow Onset, Sarah A. Yost Dec 2015

A Search For Correlations Between Gamma-Ray Burst Variability And Afterglow Onset, Sarah A. Yost

Physics Faculty Publications

We compared the time (or time limit) of onset for optical afterglow emission to the γ-ray variability V in 76 gamma-ray bursts with redshifts. In the subset (25 cases) with the rise evident in the data, we fit the shape of the onset peak as well and compared the rising and decaying indices to V. We did not find any evidence for any patterns between these properties and there is no statistical support for any correlations. This indicates a lack of connection between irregularities of the prompt γ-ray emission and the establishment of the afterglow phase. In the ordinary …
