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.

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 …

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 …
Generalized Eulerian Numbers And Multiplex Juggling Sequences, Esther M. Banaian
Generalized Eulerian Numbers And Multiplex Juggling Sequences, Esther M. Banaian
All College Thesis Program, 2016-2019
We consider generalizations of both juggling sequences and non-attacking rook placements. We demonstrate the important connection between these objects, and also propose a generalization of the Eulerian numbers. These generalizations give rise to several interesting counting problems, which we explore.

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
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 …
