#49 - Creaton And Analysis Of 3-Dimensional Thermal Models, Bradley Andrew, Ryan S. Elliott Nov 2019

#49 - Creaton And Analysis Of 3-Dimensional Thermal Models, Bradley Andrew, Ryan S. Elliott

Georgia Undergraduate Research Conference (GURC)

According to the European Commissions, the largest potential saving of energy lies within commercial and residential buildings. A considerable amount of energy loss from buildings is due to heat or infrared radiation. For this reason, we have been collecting infrared data and creating 3-dimensional models of various structures located on the University of North Georgia Dahlonega campus. Images and data were obtained using a drone and a FLIR Pro infrared camera. Using a specialized software, we were able to analyze infrared images. Through the combined use of Agisoft Metashape and many high-resolution infrared images, a 3D model with thermal data ...


Development Of 3d Thermal Models To Analyze Building Power Loss, Mark Leggiero Nov 2019

Development Of 3d Thermal Models To Analyze Building Power Loss, Mark Leggiero

Georgia Undergraduate Research Conference (GURC)

Radiative heat loss from external surfaces is a large component in overall building heat loss, and efficient methods of measuring total radiative heat loss from buildings need to be further developed. 3D thermal model analysis of such facilities can aid substantially in understanding heat loss. High-overlap radiometric images can be obtained using small aerial drones outfitted with an infrared camera, and photogrammetry algorithms can generate 3D thermal models which contain the composited radiometric data of such images. Multiple 3D models have been produced (in the OBJ file format) of buildings in the University of North Georgia’s Dahlonega campus. Current ...

Simphysics, Taylor Woods, Maidel Fletes, Mary Elizabeth Harrell, Paul Halford

Georgia Undergraduate Research Conference (GURC)

Understanding and interpreting relationships and functional trends with 2-D graphs are foundational skills in STEM fields, in other sciences and in all disciplines that utilize data analysis. Introductory physics courses regularly start with the topic of kinematics which heavily utilizes 2-D graphs that describe motion. This is why difficulties that students face in understanding 2-D graphs surface early on in physics. Yet, for this same reason kinematics can be used as a great opportunity to teach graphing skills in general. The primary goal of this project is to develop an interactive intelligent tutoring system (PhysicsSim) that makes use of kinematics ...


Two Applications Of High Order Methods: Wave Propagation And Accelerator Physics, Oleksii Beznosov Nov 2018

Two Applications Of High Order Methods: Wave Propagation And Accelerator Physics, Oleksii Beznosov

Shared Knowledge Conference

Numerical simulations of partial differential equations (PDE) are used to predict the behavior of complex physics phenomena when the real life experiments are expensive. Discretization of a PDE is the representation of the continuous problem as a discrete problem that can be solved on a computer. The discretization always introduces a certain inaccuracy caused by the numerical approximation. By increasing the computational cost of the numerical algorithm the solution can be computed more accurately. In the theory of numerical analysis this fact is called the convergence of the numerical algorithm. The idea behind high order methods is to improve the ...


The Undeniable Attraction Of Lunar Swirls, Cierra Waller, Dhananjay Ravat Nov 2018

The Undeniable Attraction Of Lunar Swirls, Cierra Waller, Dhananjay Ravat

Posters-at-the-Capitol

Lunar swirls are complex patterns on the Moon with distinct brightness signatures and magnetic characteristics. Current research has suggested that the formation of lunar swirls relies on local magnetic fields to shield impinging solar wind, based on a shift in electromagnetic wavelength peaks related to solar radiation and space weathering. Our research combined recent models and methods to characterize these anomalies at the surface of the Moon, exploring the effects of field strength and position. We have produced a high resolution map of a famous swirl named Reiner Gamma using magnetic dipole modeling. These maps and models are considered when ...


The Relationship Between Electrical Conductivity And Magnetically Damped Motion, Kalem Akhtar Jun 2018

The Relationship Between Electrical Conductivity And Magnetically Damped Motion, Kalem Akhtar

The International Student Science Fair 2018

Varying electrical conductivities of different, non-magnetic metals appears to affect the magnitude of magnetically damped motion. To determine the relationship between magnetic damping and conductivity an experiment was designed using different length tubes of aluminium, copper and brass. The tubes had the same diameter and similar wall thickness. A short, cylindrical neodymium magnet was dropped through the tubes of and the time for the magnet to traverse the tube was recorded using a smartphone camera. These times allowed for the terminal velocity to be calculated for each metal length and the average terminal velocity for each metal was determined. This ...

Electricity, Light And Semiconductors, Josephine Zhao

The International Student Science Fair 2018

As technology advanced these days, computers are playing a more and more important role in our daily life; especially in those areas that requires higher technology, for example, aerospace. And as computers keep developing, they tend to be smaller and lighter but much more sufficient. It is the base stone of modern information era. A CPU is the brain of a computer, and as the computers get smaller and smaller, the CPUs are getting smaller and smaller, using semiconductors. Semiconductors have many properties that is extremely useful to human, their conductivity are controlled by their environment, and therefore are adaptable ...

Calibration Of Temperature Sensors In Preparation For The 2017 Total Solar Eclipse, Erick Agrimson, Kaye Smith, Ana Taylor, Vina Onyango-Robshaw, Rachel Lang, Alynie Xiong, Peace Sinyigaya, Grace Maki, Rachel Dubose, Brittany Craig, James Flaten, Gordon Mcintosh Oct 2017

Calibration Of Temperature Sensors In Preparation For The 2017 Total Solar Eclipse, Erick Agrimson, Kaye Smith, Ana Taylor, Vina Onyango-Robshaw, Rachel Lang, Alynie Xiong, Peace Sinyigaya, Grace Maki, Rachel Dubose, Brittany Craig, James Flaten, Gordon Mcintosh

2017 Academic High Altitude Conference

In preparation for the 2017 total solar eclipse, St. Catherine University developed a calibration protocol for the temperature sensors flown during thermal wake boom experiments. The calibration method used a standard two-point technique that corrected each individual sensor for both slope and offset errors using a high quality NIST certified thermocouple as the temperature standard. Our method is not absolute but corrects each sensor relative to the NIST standard so that we feel some confidence that individual sensor variations are mitigated. In preparation for the eclipse, calibration curves were generated for over 200 individual digital and thermistor temperature sensors.


Controlled Heading Automation Device, Robert Coulson Oct 2017

Controlled Heading Automation Device, Robert Coulson

2017 Academic High Altitude Conference

One of the most significant limitations of weather balloon-based data collection is that instruments and payloads cannot depend on particular orientations or predictable rotation. Several investigators have used payload heading control devices to overcome this limitation in order to collect directional data and record motion controlled video footage. The work described in this presentation builds on the Controlled Heading Automation Device (CHAD) developed by Kruger et al. (2016) and was carried out at DePaul University in summer 2017 as an undergraduate research project. Our goal was to record stable video of the shadow of the moon on Earth’s surface ...


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 ...


Space Traffic Management Concepts Leveraging Existing Frameworks, Stephen K. Hunter Nov 2016

Space Traffic Management Concepts Leveraging Existing Frameworks, Stephen K. Hunter

Space Traffic Management Conference

Leveraging existing U.S. regulatory frameworks, as well as international organizations, will dramatically shorten the time needed to develop an effective Space Traffic Management concept. Both the Department of Defense and the Department of Transportation have been working with the U.S. Congress to define and develop a Space Traffic Management concept that will allow the Office of Commercial Space Launch to begin a new mission that will help to ensure the safety and resilience of the space domain. Outside observers can easily see forward progress toward this, still, undeveloped concept. This paper explores potential final U.S. Space Traffic ...

Bicrystallography In Two Dimensions: A Graphical Procedure And Comparison Of Its Results To Experiments, Andrew M. Maas, Peter Moeck May 2015

Bicrystallography In Two Dimensions: A Graphical Procedure And Comparison Of Its Results To Experiments, Andrew M. Maas, Peter Moeck

Student Research Symposium

Three dimensional (3D) bicrystallography describes ideal structures of grain boundaries comprehensively at the atomic level as a function of the five macroscopic and two of the four microscopic parameters [1,2]. Free energy minimization of these structures leads to the real structure of these topologically distinct regions within crystals. These minimizations may either reduce the symmetries of ideal bicrystals or leave them intact. Since the symmetries of physical properties need to be compatible (by the Shubnikov-Curie and Curie-Minnigerode-Neumann principles [3]) with the symmetries of the atomic arrangements from which they arise, bicrystallography allows for predictions about which phenomena can occur ...


Ionic Alkalihalides As Pressure Media In Dac Experiments, Julius Monello Aug 2011

Ionic Alkalihalides As Pressure Media In Dac Experiments, Julius Monello

Undergraduate Research Opportunities Program (UROP)

In Diamond Anvil Cells (DACs), usually a pressure transmitting medium functions to transform the uniaxial pressure supplied by the opposing diamond anvils into uniform hydrostatic pressure acting on the sample. Conventionally, a 4-1 methanol-ethanol solution, or a 16-3-1 methanol-ethanol-water solution is used as pressure transmitting medium. However, these two solutions transform into a glass with high elastic shear strength at pressures around 12-14 GPa and no longer function as hydrostatic medium. Our goal was to determine if liquid ionic alkalihalide alkanolate complexes will provide more uniform pressure in the cell up to 20 GPa. Ruby (Cr-doped AlP,) produces two Cr ...
