Real-Time Video Processing Of Arcing Events To Determine Coincidence, Jr Dennison, Gregory Wilson, Jonh Mojica Decena, Brian Wood

Posters

A system has been developed and tested for real-time monitoring of environmentally-induced electrostatic discharge events to test spacecraft component and material survivability. Simultaneous detection by several parallel methods in coincidence, enhances event detection, minimizes false signals, and collects complementary information to determine arc location, intensity, and timing. This research focuses on four computer-interfaced video cameras which provide spatial and temporal detection of visual arcing from the surface of various elements. A real time processing solution was developed which can calculate integrated intensities, sensitively detect intensity threshold events, and store relevant video frames from these threshold events. Post processing of this …

An Expanded Modern Coexistence Theory For Empirical Applications, Stephen P. Ellner, Robin E. Snyder, Peter B. Adler, Giles J. Hooker

Ecology Center Publications

Understanding long‐term coexistence of numerous competing species is a longstanding challenge in ecology. Progress requires determining which processes and species differences are most important for coexistence when multiple processes operate and species differ in many ways. Modern coexistence theory (MCT), formalized by Chesson, holds out the promise of doing that, but empirical applications remain scarce. We argue that MCT's mathematical complexity and subtlety have obscured the simplicity and power of its underlying ideas and hindered applications. We present a general computational approach that extends our previous solution for the storage effect to all of standard MCT's spatial and temporal coexistence …

To address challenges of assessing space weather modeling capabilities, the CommunityCoordinated Modeling Center is leading a newly establishedInternational Forum for Space WeatherModeling Capabilities Assessment. This paper presents preliminary results of validation of modeled foF2 (F₂ layer critical frequency) and TEC (total electron content) during the first selected 2013 March storm event (17 March 2013). In this study, we used eight ionospheric models ranging from empirical to physics-based, coupled ionosphere-thermosphere and data assimilation models. The quantities we considered are TEC and foF2 changes and percentage changes compared to quiet time background, and the maximum and minimum percentage changes. In addition, …

Osl-Irsl Ages Of Two, Perhaps Three, Pre-Bonneville Deep-Water Pluvial Lakes In Cache Valley, Utah-Idaho: Implications Of Their Unexpected High Altitudes For Excavation Of Cutler Narrows From A Level Above 1494 M (4901 Ft), Down To The Present Level Of 1314 M (4310 Ft) Mainly During The Bonneville Lake Cycle, Robert Q. Oaks Jr., Susanne U. Jänecke, Tammy M. Rittenour, Thad L. Erickson, Michelle S. Nelson

Geosciences Faculty Publications

Pluvial-lake highstands in the Bonneville basin are known to be contemporaneous with periods of Quaternary glaciation. At least five lake cycles have been identified from prior studies of two deep cores (Eardley and Gvosdetsky, 1960; Eardley and others, 1973) and several isolated outcrops in the main part of the Bonneville basin and eastward in Cache Valley. These are the Lava Creek B (~620 ka, marine isotope stage MIS 16), Pokes Point (~420 ka, MIS12), Little Valley (~150 ka, MIS 6), Cutler Dam (~60 ka, MIS 4), and Bonneville (~18 ka, MIS 2) lake cycles (Oviatt and others ,1987, 1999; Lisiecki …

Cache Valley: A Critical Part Of Lake Bonneville Preserves Evidence For A Protracted Bonneville Highstand, Possible Tectonic Triggers Of The Bonneville Flood, Liquefaction, And Clustered Earthquakes On The East And West Cache Fault Zones, Susanne U. Jänecke, Robert Q. Oaks Jr., Tammy M. Rittenour, A. J. Knight, Justin Oakeson, Nathan Ellis

Geosciences Faculty Publications

Geologic, geomorphic, and geophysical analyses of landforms, sediments, and structures in conjunction with new radiocarbon (¹⁴C) and optically stimulated luminescence (OSL) age determinations document a revised history of flooding and recession of Lake Bonneville in Cache Valley, Idaho and Utah. The presence of wave-cut cliffs in bedrock throughout the Bonneville basin show that the Bonneville highstand was protracted. Triangular facets were cut into bedrock in the footwalls of normal faults, and were steepened significantly by wave erosion at the highest Bonneville shoreline.

The Bear River's Diversion, The Cutting Of Oneida Narrows At 55-50 Ka, And Relations To The Lake Bonneville Record, Joel Pederson, Tammy M. Rittenour, Susanne U. Jänecke, Robert Q. Oaks Jr.

Geosciences Faculty Publications

The Bear River's course has shifted over Quaternary time, and its late Pleistocene integration into the Bonneville basin long has been recognized as a possible explanation for why Lake Bonneville was apparently larger than the preceding lakes in its basin, and the only one to overflow its topographic threshold.

The middle-Pleistocene Bear River joined the Snake River to the north, likely via the Portneuf River drainage. Then an episode of volcanism in the Blackfoot-Gem Valley volcanic field ~100–50 ka diverted the Bear River southward into Gem Valley. Previous chronostratigraphic and isotopic work on the Main Canyon Formation in southern Gem …

Cognitive Load Affects Numerical And Temporal Judgments In Distinct Ways, Karina Hamamouche, Maura Keefe, Kerry Jordan, Sara Cordes

Psychology Faculty Publications

Prominent theories suggest that time and number are processed by a single neural locus or a common magnitude system (e.g., Meck and Church, 1983; Walsh, 2003). However, a growing body of literature has identified numerous inconsistencies between temporal and numerical processing, casting doubt on the presence of such a singular system. Findings of distinct temporal and numerical biases in the presence of emotional content (Baker et al., 2013; Young and Cordes, 2013) are particularly relevant to this debate. Specifically, emotional stimuli lead to temporal overestimation, yet identical stimuli result in numerical underestimation. In …

Characterization Of The Effects Of Radiation On Skeletal And Smooth Muscle Cells, Lori Caldwell, Charles Harding, Jr Dennison, Elizabeth Vargis

Posters

Muscular atrophy is a serious issue for extended spaceflight. Understanding and preventing the role of ionizing radiation in skeletal muscle loss would preserve the strength and endurance of astronauts and enable longer duration space travel and exploration. Irradiation was performed in the USU material physics group's Space Suvivability Test Chamber. C2C12 and CRL-1999 cells were exposed to dosages ranging from 0.5 - 36.8 Gy. Cell viability and growth rate were measured immediately following irradiation.
