Development Of Ion Beam Nuclear Transmutation Doping (Ibntd) For Novel Electronics In Extreme Conditions, Michael G. Pravica, Noel A. Guardala, Jack L. Price

NSTec UNLV Symposium

Development of IBNTD for electronics under extreme conditions.

•We hope to create novel wide bandgap devices using Ion Beam Nuclear Transmutation Doping (IBNTD). These devices may be used as rugged high power switches, and high current/low noise amplifiers. Diamond in itself represents a “Holy Grail” for electrical applications due to its very high thermal conductivity and excellent electrical characteristics.
•We also hope to develop devices that can convert the enormous energy from high-energy nuclear particles (α2+,β-,β+, γparticles) into useful electricity and thus harness the enormous energy still contained in “spent” nuclear fuel. Developing these direct energy conversion (DEC) devices would …

Development Of Smart Pv Inverters For The Smart Grid, Yahia Baghzouz

NSTec UNLV Symposium

The Electric Grid has become more complex with recent technological developments. There are more alternative power sources and sensors added into the mix at every part of the grid. The Energy Meter has changed over the past several years as well. The older meters were checked only once a month with a meter reader, but the new "Smart" Meters are capable of reporting energy usage at fifteen minute intervals.

Second Life Virtual Universities: A Visual Analysis, Zeenath Haniff

Graduate Research Symposium (GCUA) (2010 - 2017)

General academic objectives include producing an educational experience that is engaging, interactive, collaborative, experiential and productive. The goal is to promote learner engagement through the visual power of a newly adopted medium in education – universities in the multi-user virtual environment (MUVE) of Second Life. Attributes of the virtual reality aid visual learning in the online environment: (1) computer-generated content, (2) three-dimensional graphics, and (3) interactivity. Visual renditions of campus buildings and fellow students as avatars emotionally connect students to feel a sense of presence and community within the virtual learning platform. Additionally, the ability to see and hear their …

Adaptation Of The Nevada Climate Change Data Portal Web Interface To Small-Screen Mobile Devices, Tsvetan Komarov

Festival of Communities: UG Symposium (Posters)

Robust and convenient access to the Nevada Climate Change Data Portal is vital for the project’s success, because of the researchers’ need to gather and analyze large volumes of data with minimal effort. However, the current version of the data portal web interface is not optimized for small-screen mobile devices such as mobile phones, PDAs, iPads, NetBooks, and others. The proposed research will address this issue by exploring the current methods for creating a client-aware web interface adaptable to the variety of small-screen devices, designing and implementing the most appropriate solution, and finally, user testing of the implemented solution.

How Science Is Visually Portrayed In The Media: An Examination Of Science Times, Rachel Toyer, Larry Mullen

Graduate Research Symposium (GCUA) (2010 - 2017)

This poster will illustrate preliminary findings of how science images are portrayed in the New York Times, specifically, the Science Times section that is published every Tuesday and has grown in readership and popularity. Science images, five issues per year, have been coded over the past 34 years since the Science Times section first appeared in print. Our work follows trends that observe types of images, how many images are present, and whether the image is a photo or graphic of some sort.
