Using Genetic Algorithm to solve Fisk University's Athletic Department Travel Routes |
Jayson Ambrose At Fisk University, all teams under the athletic department can only travel to cities or states within a certain radius to keep the loss of funds to a minimum. But there is not a primary strategy on which route to pursue in relation to the circuit of cities that the teams have to travel. The framework behind the team's travelling system reveals that the teams travel in their own directions to several cities and states to promote the university's athletic department, which it does, but it also causes the department expenses to increase due to the inconsistency of distances and lack of controlled travel range. In this thesis, we re-introduce the concept of genetic algorithm through the Travelling Salesman Problem, using its evolution of genes procedure to generate the best routes for each team to travel the minimum amount of miles. We chose the technique of genetic algorithm because it is efficient when dealing with complex problems. It can reduce the initial distance by approximately 44.5% after processing several times to generate the best distance. We implemented a body of codes that continuously executes and stores the total distances of each route created to display the results in descending order where the smallest number of distance is the best route. We expect this new approach to be beneficial to the universities athletic department as well as others who may encounter this problem because it finds the shortest route to travel which reduces the rate of money loss drastically. |
Macro-Scale Modeling of Deflagration to Detonation Transitions in Large Arrays of Explosives |
Jacqueline Beckvermit, Andrew Bezdjian, Todd Harman, Qingyu Meng, Alan Humphrey, John Schmidt, Martin Berzins and Charles Wight |
The physical mechanism and constraints required for Deflagration to Detonation Transitions (DDT) in a large number of explosive devices is investigated. Motivation for this work comes from a 2005 transportation accident in Spanish Fork Canyon, where a truck carrying 36,000 pounds of seismic boosters overturned, caught fire and detonated. The explosion created a crater 30 feet deep by 70 feet wide in the middle of the highway.

Visualization of 3D Home Ranges for a California Condor Breeding Pair |

The critically endangered California condor (Gymnogyps californianus) is the one of the largest vultures in the world, and its wingspan of approximately three meters is the widest of any North American bird. California condors nest in cliffs and feed exclusively on carrion. As a result of shooting, lead poisoning from carcasses, poisoning, pesticides, and other anthropogenic impacts, condor populations declined to near-extinction in the 1980s. In 1987, the 22 remaining wild condors were captured and brought into a captive breeding program at the San Diego Safari Park, the Los Angeles Zoo, and the World Center for Birds of Prey. The success of these intensive captive breeding efforts led to more than 100 eggs being laid by captive condors by 1994. Following captive propagation, condors were released in California, Arizona, and Sierra San Pedro de Martir National Park in Baja, Mexico. Today, there are around 430 condors with over 200 free-ranging in the wild. Condors reintroduced to their former range in Baja Mexico by San Diego Zoo Global are telemetered with solar-powered global positioning system (GPS) receivers so that they can be tracked at high-resolution (< 20m) for long periods to date (some for over eight years). These data enable condor managers and scientists to monitor the spatial behaviors and habitat use of the wild birds and enhances the conservation management of this iconic species. The restoration of California condors is a great conservation success story. However, condor populations still face serious challenges to their recovery, including lead poisoning and the emerging threat of impacts from renewable energy developments.
Plasma Dynamics and Confinement |
Greg Foss, Anne Bowen, Wendell Horton and Lee Leonard |
The rotation of the earth creates a Coriolis force that makes what would be a converging or diverging motions in the atmosphere into a vortex. The structures of these waves and vortices is of interest because they significantly influence global atmospheric circulation. In intense forms, they create the storms and seed the atmosphere for tornadoes and hurricanes. The physics of the vortex structure continues to heights of 100 kilometers and beyond where solar radiation ionizes the nitrogen and oxygen molecules in the air, making the gas plasma. These plasma structures can scatter the RF signals used in global navigation systems. The study of the generation and dynamics of planetary waves that are induced by this force in the ionospheric plasma has accordingly been a subject of a great deal of theoretical and experimental investigations in recent years. Dr. Wendell Horton's research group at the University of Texas at Austin, Institute for Fusion Studies, investigates the dynamics of plasma vortices using the XSEDE funded Stampede petascale supercomputer. Data from their simulations are being visualized by the Texas Advanced Computing Center's vis team, allowing the researchers to see the full three-dimensional structure and dynamics of these vortices for the first time. The submitted movie shows the progression of visualizations that enabled the science team to analyze the overall dynamics of the system, and explore some of the visualization techniques available.
Streamwise Vorticity in a Supercell Thunderstorm Simulation |

The animation and accompanying images compare variables from a high resolution simulated thunderstorm, a storm that spawned a tornado. These graphics illustrate how vorticity in the environment aligns with the wind feeding into a storm, enhancing storm rotation.
Spherical Visualization: Mapping the 2014 Winter Olympics |
Karla Vega, Tassie Gniady, Patrick Beard and Eric Wernert |
Students and staff at the Advanced Visualization Laboratory at Indiana University created this visualization to explore data analysis and visualization techniques of major social global events. For this visualization, the effort was focused on the Sochi 2014 Winter Olympics. The data was obtained through several online resources, as well as data scrapped from social networks. The major purpose of this project was to gain a better understanding of how to interact with these types of data, engage the digital humanities community, and to create visualizations for spherical displays, in particular for the National Oceanic and Atmospheric Administration's Science On a Sphere (SOS) system. The outcome was a series of software tools developed to handle the techniques that are shown in this animation, as well as a series of visualizations that were distributed to the SOS community.
