Comparative Analysis Of Rgb-Based Eye-Tracking For Large-Scale Human-Machine Applications, Brett Thaman, Trung Cao
Comparative Analysis Of Rgb-Based Eye-Tracking For Large-Scale Human-Machine Applications, Brett Thaman, Trung Cao
Posters-at-the-Capitol
Gaze tracking has become an established technology that enables using an individual’s gaze as an input signal to support a variety of applications in the context of Human-Computer Interaction. Gaze tracking primarily relies on sensing devices such as infrared (IR) cameras. Nevertheless, in the recent years, several attempts have been realized at detecting gaze by acquiring and processing images acquired from standard RGB cameras. Nowadays, there are only a few publicly available open-source libraries and they have not been tested extensively. In this paper, we present the result of a comparative analysis that studied a commercial eye-tracking device using IR …
Weather And Climate Research At The Kentucky Climate Center Based On Mesonet Observations, Brittany Pekara, Eric Rappin
Weather And Climate Research At The Kentucky Climate Center Based On Mesonet Observations, Brittany Pekara, Eric Rappin
Posters-at-the-Capitol
The Kentucky Mesonet is a great asset for the Commonwealth of Kentucky in a multitude of ways, from real-time storm monitoring to building a detailed climate record. A detailed climate record is essential as causality between observations and extreme weather can be identified, making it a great tool in an evolving climate system. The climate record being developed at the 75+ Kentucky Mesonet observation stations consists of approximately 75 indices that reflect frequency, extremes, range, duration, trends of precipitation, droughts, and extreme temperatures. Calculations are done for daily, weekly, monthly, seasonal, bi-annual, and annual aggregation periods. Tools will also be …
Design And Construction Of A Modular Nai(Tl) Detector Array For Use In The Parity- And Time Reversal Violation Measurements For Noptrex, Jon Mills, Jason Fry
Design And Construction Of A Modular Nai(Tl) Detector Array For Use In The Parity- And Time Reversal Violation Measurements For Noptrex, Jon Mills, Jason Fry
Posters-at-the-Capitol
The goal of the NOPTREX collaboration is to probe the Standard Model by utilizing the properties of low energy neutron-nucleus resonances to find evidence of parity- and time-reversal-odd violations. In order to conduct these sensitive experiments, it is needed to design and simulate an array of modular, high precision NaI(Tl) detectors. These detectors will be designed to operate in both pulse and current modes. We have tentative beam time at LANSCE to perform a search for new parity violation in heavy nuclei as candidates for time reversal and to perform a research and development effort on the n+d=t+gamma experiment. We …
Mapping Of Non-Native Invasive Plant Species Using Remote Sensing And Gis: Assessment Of Human Impact On Kudzu (Pueraria Montana) Spread, Harshitkumar Godhasara
Mapping Of Non-Native Invasive Plant Species Using Remote Sensing And Gis: Assessment Of Human Impact On Kudzu (Pueraria Montana) Spread, Harshitkumar Godhasara
Scholars Week
Remote sensing methods provide tools to identify and map non-native plants. Biophysical characteristics of plants can be utilized to recognize and distinguish non-native invasive plants from other native plant species. Kudzu is an invasive plant, which causes economic loss and decreases biodiversity. Moreover, kudzu doubles emission of nitric oxide and increases ozone pollution. The impact of human activities on the spread of noxious plant species like kudzu can be assessed utilizing remote sensing and geographic information systems (GIS) tools. Kudzu spread in the USA was mapped using in situ data including the actual coordinates of kudzu sites. Geographic distribution of …
Revisiting The Cretaceous-Paleogene Boundary In Western Kentucky, Usa, Jarred Asselta
Revisiting The Cretaceous-Paleogene Boundary In Western Kentucky, Usa, Jarred Asselta
Scholars Week
This study revisits a Cretaceous-Paleogene (K-Pg) sedimentary section in western Kentucky to determine the nature of this boundary and the depositional environments. Although previous pollen work identified the boundary over four decades ago, to our knowledge no work has been carried out at this important K-Pg boundary site. A combination of stratigraphy and sedimentology were used to characterize the section in detail. Bulk and oriented samples were collected for grain-size, geochemical, and petrographic analysis. We relocated the site and measured 1.5m of section that includes the K-Pg boundary. Four distinct units were identified and from base to top of section …
Exploring The Geometric And Electronic Properties Of Palladium Doped Silicon Clusters, Madison Winkeler, Ciara N. Richardson
Exploring The Geometric And Electronic Properties Of Palladium Doped Silicon Clusters, Madison Winkeler, Ciara N. Richardson
Scholars Week
Transition metal-doped silicon clusters have unique properties and have been studied as building blocks for nanomaterials and microelectronics. Here, the structure and properties of candidate palladium doped silicon clusters (SinPd2: n=1-17) were determined using global optimization techniques on a high performance computing cluster at the San Diego Supercomputing Center. Then geometric structures were further optimized utilizing the B3LYP method with 6-311+G(d) basis sets for silicon and lanl2dz pseudopotential for palladium, followed by the larger DSDPBEP86 method with 6-311+G(2d) basis sets for silicon and SDD pseudopotential for palladium, as implemented in the Gaussian 16 program package. The energetics for each cluster …
