Mapping Community Space And Place In Mto Wa Mbu, Tanzania Through Surveys And Gis, Jessica Craigg

Georgia College Student Research Events

Cities throughout the African continent have been developing at an unprecedented pace, many of them due to the influence of the tourism industry. This is particularly true in Tanzania, a country famous for its national parks and their draw to tourists who help provide money for development. However, the only way to get the whole story on how to spend this money is through the experiences and needs of the people themselves. This study focuses on a small town in northeastern Tanzania, Mto wa Mbu, situated near Lake Manyara National Park, and its people’s perceptions of the park and community. …

Fermi-Lat Daily Monitoring Observations Of The Microquasar Cygnus X-1, Austin P. Waldron, Stephen R. Hood, Arash Bodaghee

Georgia College Student Research Events

Detection of gamma-ray emission from microquasars is important for understanding particle acceleration in the jet, and for constraining leptonic/hadronic emission models. We present a continuation of a 1-d likelihood analysis on gamma-ray observations by Fermi-LAT (0.1-10 GeV) of the accreting black hole candidate Cygnus X-1. Combining this gamma-ray data with available X-ray monitoring data from Swift and MAXI allowed us to reveal over a dozen days (in 2008-2016) during which Cyg X-1 displayed low-significance (3-4 sigma) excesses, many of which were contemporaneous with apparent transitions in the X-rays.

Using An Atomic Molecular Optics Laboratory For Undergraduate Research And Mentoring Of Physics Students In Georgia, Matthew P. Dallas

Using an Atomic Molecular Optics Laboratory for Undergraduate Research and Mentoring of Physics Students in Georgia

An Atomic and Molecular Optical (AMO) Physics research lab is an excellent tool to train and mentor undergraduate students in advanced laboratory techniques. Students gain valuable basic experience in experimental designs, data acquisition techniques, working with high precision optical equipment, building electronics, and working in the machine shop. The current project is building and testing an enclosure for the diode laser to reduce sound and vibrational interference. In addition, we are developing and evaluating a new, more compact laser cavity which is 3d printed. …

Key Encryption Through Quantum Optics, Madison Durrance, Zach Galberd, Abbey Savage, Tristan Cabrera, Josh Hoffman

Georgia College Student Research Events

Cryptography has been around since the dawn of human civilization to send private messages for commercial, military, and political purposes. Some of the most important ciphers are the Vigenère cipher, the enigma, and the more modern RSA. Because of the development of the internet, private encryption has also become increasingly more important. The weakest link of encryption is the key creation and key distribution. A key is needed to encrypt and decipher codes and is needed by both the user and sender. A solution to this problem is the generation of quantum key distributions. In our experiment, we are now …

Analyzing The Kinetics Of A Bromophenol Blue Fading Reaction In Basic Conditions For An Undergraduate Lab, Zeljka Popovic

Georgia College Student Research Events

Bromophenol blue is a common pH indicator and dye used in many different industries. Once a solution of bromophenol blue is placed in a concentrated basic solution, the color fades from a blue/violet color to clear solution with a pH of 4.6 or greater. The rate law of the reaction is analyzed through the use of a small footprint visible-near-infrared spectrometer (Vis-NIR) with a diode array detector. An absorbance wavelength of 590 nm as a function of time was collected using Ocean Optics OceanView software. The results contained in the data collection file are exported to a spreadsheet for further …

Testing The Feasibility Of A Bladeless Wind Turbine Design, Chukwuemeka C. Ibebuike, Hauke Busch

Georgia College Student Research Events

In this era of increased global warming, the immediate reduction of CO2 emission is of great importance to the survival of humanity. Wind power can go a long way to offer a better alternative to generate sustainable power without producing any CO2 gas. The reductions of CO2 emissions are of significant importance to humanity. Wind power can offer a better alternative to generate sustainable power without producing CO2. Traditional turbines consist of rotating blades while a Bladeless turbine would significantly simplify the design. This would offer possible improvements such as cost savings, reduction of the operating noise level, simplification of …

3d Printing Plastic Scintillators, Madison Durrance, Nicolas Merino, Emily Vanderwolf

Georgia College Student Research Events

Scintillation is the production of visible light in a transparent material when exposed to either an electron, ion, or some other high energy particle. There are many ways to manufacture scintillators, but unfortunately many of these methods involve the costly machining of crystal materials. We plan to reduce this cost by attempting to manufacture plastic scintillators using a 3D printer. The most difficult challenge has been making transparent prints. We have had success with PET filament, the same plastic used in soda bottles. Upon successful clear prints, we intend to use recycled bottles to manufacture our own doped fiber. Organic …

Kinetics Of Crystal Violet Color Fading Via A Small Footprint Diode Array Spectrometer, Paige Lott

Georgia College Student Research Events

Crystal violet is a pH indicator and is commonly used to classify bacteria. In acidic solutions, crystal violet is yellow in color and at approximately the pH of 1.6, it transitions to a violet color. Over time, this violet color fades as it reacts with the CO 2 in the air until it is clear. A small footprint visible-near- infrared spectrometer (Vis-NIR) with diode array detector was employed in this investigation. Using the software that operates the spectrometer, the absorbance of crystal violet solutions can be measured at 585 nm at high concentrations of base as a function of time. …

Pop-Up Java: An Augmented Reality Mobile Game To Teach Java, Richard Myers

Georgia Undergraduate Research Conference

As computers become more and more ubiquitous, it becomes increasingly important and prevalent to teach coding. Coding builds important life skills such as organization, higher order thinking, self-esteem, socialization and teamwork, among many others. However, learning the skills necessary to design and create an efficient program from scratch takes a lot of practice that can often be confusing and frustrating to newcomers.

There are a large number of programming languages in the world, each with their own merits. The TIOBE Programming Community Index calculates the popularity of programming languages by tallying search queries on major search engines, and shows that …
