The purpose of this project was to collect rainfall samples and record the data in such a way that tested a hypothesis. My hypothesis is that the area in Clarksville, Tennessee where the samples are collected will collect up to eight inches of rain for the thirteen week time span.


Grouping Digits As A Method For Increasing Computation Speed Of Galois Field Arithmetic For Erasure Coding Applications, John Andrew Burnum Dec 2015

Grouping Digits As A Method For Increasing Computation Speed Of Galois Field Arithmetic For Erasure Coding Applications, John Andrew Burnum

Haslam Scholars Projects

The performance of multiplications in Galois Field arithmetic using the GROUP method is measured, described, and analyzed using the GF Complete open-source library. Galois Field arithmetic is vital for many erasure coding methods, including Reed-Solomon coding, and the GROUP method is a simple and modular technique for increasing computation speed.


Exploring Rapid Radiochemical Separations At The University Of Tennessee Radiochemistry Center Of Excellence, Howard L. Hall, John D. Auxier Ii Nov 2015

Exploring Rapid Radiochemical Separations At The University Of Tennessee Radiochemistry Center Of Excellence, Howard L. Hall, John D. Auxier Ii

Faculty Publications and Other Works -- Institute for Nuclear Security

The University of Tennessee formed its Radiochemistry Center of Excellence (RCoE) in 2013 with support from the U.S. National Nuclear Security Administration. One of the major thrusts of the RCoE is to develop deeper understanding of rapid methods for radiochemical separations that are relevant to both general radiochemical analyses as well as post-detonation nuclear forensics. Early work has included the development and demonstration of rapid separations of lanthanide elements in the gas phase, development of a gas-phase separation front-end for ICP-TOF-MS analysis, and the development of realistic analytical surrogates for post-detonation debris to support methods development.

Upon infection of a new host, human immunodeficiency virus (HIV) replicates in the mucosal tissues and is generally undetectable in circulation for 1–2 weeks post-infection. Several interventions against HIV including vaccines and antiretroviral prophylaxis target virus replication at this earliest stage of infection. Mathematical models have been used to understand how HIV spreads from mucosal tissues systemically and what impact vaccination and/or antiretroviral prophylaxis has on viral eradication. Because predictions of such models have been rarely compared to experimental data, it remains unclear which processes included in these models are critical for predicting early HIV dynamics. Here we modified the …


Discontinuous Element Insertion Algorithm, Timothy James Truster Jan 2015

Discontinuous Element Insertion Algorithm, Timothy James Truster

Faculty Publications and Other Works -- Civil & Environmental Engineering

An algorithm is presented for inserting zero-thickness interface elements, termed herein as “couplers”, into continuous finite element meshes in two and three dimensions. Insertion is governed solely by the mesh topology and is specified according to regions or subdomains within the overall analysis domain, a geometrically intuitive means to designate the coupler locations. The algorithm is self-contained and requires only nodal coordinates and element connectivity as input. A wide class of volume elements and interface couplers are treated within the framework. Since the algorithm is topologically-based, interfaces of arbitrary complexity are naturally accommodated. Separate treatment is given to inserting couplers …

To Play Or Not To Play? That’S A Resource Abundance Question, Jeremy David Auerbach, Andrew R. Kanarek, Gordon M. Burghardt Jan 2015

To Play Or Not To Play? That’S A Resource Abundance Question, Jeremy David Auerbach, Andrew R. Kanarek, Gordon M. Burghardt

Faculty Publications and Other Works -- Ecology and Evolutionary Biology

Although play occurs in a wide variety of animals, models of the origins of play behavior are lacking. We propose a novel computational model exploring the evolution of non-social frivolous play. Asexually reproducing semelparous animals can either rest or forage. Foraging occurs when an organism is below an energy threshold. Success is determined by the combination of skill and availability of resources, which declines over time but replenishes for each generation. Play was introduced as a mutant strategy: a frivolous activity that uses energy and increases the probability of dying over resting with no direct fitness benefit. Simulations show that …
