Searching For The Origins Of Matter, Joshua L. Barrow May 2017

Searching For The Origins Of Matter, Joshua L. Barrow

Andrews Research Conference

The big bang and inflation are experimentally confirmed by multitudes of astronomical observations, yet theoretical tension still exists upon a very important question: why is there something rather than nothing? In other words, why are there unequal amounts of matter and antimatter? Why did a supposedly initially symmetric state not annihilate perfectly?

The breaking of this symmetry has allowed for all of material existence--also known as baryogenesis, the prevalence of matter over antimatter--and yields the theoretical possibility of direct detection by observation of baryon number violating mechanisms, which have previously never been observed.

One such plausible mechanism can be found ...


Stacking 2d Materials, Michael Hernandez, John C. Mann Mar 2017

Stacking 2d Materials, Michael Hernandez, John C. Mann

Seaver College Research And Scholarly Achievement Symposium

Monolayer Transition Metal Dichalcogenides are atomically thin semi-conductors that are considered quasi 2D materials due to their extremely small thickness. It has been observed that atomically thin crystals exhibit different physical properties than their bulk counterparts due to quantum confinement effects. We are attempting discover new physical properties by developing a technique to stack two different monolayer crystals, MoS2 and MoSe2.


The Property Of Mass: An Interdisciplinary Metaphysical Investigation, Benjamin Hayworth Mar 2017

The Property Of Mass: An Interdisciplinary Metaphysical Investigation, Benjamin Hayworth

Student Research and Creative Activity Fair

The property of mass as used in the physical sciences is somewhat of a metaphysical conundrum. Not only has the definition of mass changed with various paradigm shifts in physics, but the powers belonging to the property have also varied. In my study, I begin by examining the historical context surrounding the term, including the changes to its definition. In doing so, it is revealed that various definitions of mass are used and circulated in general discussion, so a cogent criterion of identity is established by which each definition can be measured. After determining the distinctions between each mass term ...


Between-Day Reliability Activity Fluctuations In Young Adults At Baseline And 6-Months Follow-Up, Connor J. Wicks Mar 2017

Between-Day Reliability Activity Fluctuations In Young Adults At Baseline And 6-Months Follow-Up, Connor J. Wicks

Student Research and Creative Activity Fair

Human Daily Motor Activity (DMA) is characterized by complex temporal fluctuations and scale invariance. DMA is estimated from a time series composed of continuous amounts of activity recorded with the Actigraph GT9X monitor. The purpose of this study was to measure the complex temporal fluctuations in several young healthy adults over a 7-day period. After six months there was a follow-up of another 7-day period. Future collections will involve healthy older adults and adults with Parkinson’s disease. For the first phase of this study, 24 healthy young adults wore the monitor on their non-dominant hand for seven straight days ...

A Review Of High Frequency Radio Wave Absorption, David Alan Smith Dec 2016

A Review Of High Frequency Radio Wave Absorption, David Alan Smith

David Smith

Although the technology dates back nearly to Marconi and his wireless telegraph, the high-frequency (HF) radio spectrum continues to be a useful communications medium.  Since long-distance HF propagation depends on the ionosphere, HF propagation is subject to variations in ionospheric characteristics.  Chief among these characteristics is the density of free electrons.  The sun provides the energy required to ionize neutral atmospheric constituents.  Hence, the production and loss of free electrons is not constant.  Day/night variations as well as the ebb and flow of the 11-year solar cycle cause changes in the density of free electrons.  In addition, space weather ...
