Long Term Ground Based Precipitation Data Analysis: Spatial and Temporal Variability
… climate indices as SOI, PDO, or Niño 3.4. Another objective is to identify how well modeled precipitation compares to gauge precipitation (ground truth) and if the composition of the indices are the same for both. A methodology for validating the generalization performance of the model is …

Human Impacts on Fire in De Soto National Forest, Mississippi, U.S.A.
<p>Fire is a common occurrence in the longleaf pine (<em>Pinus palustris</em>) forests of the Southeast United States. Prescribed fire is used to manage these threatened ecosystems, but information regarding historical fire activity is unknown. My goals were to determine the historical fire regimes …

GEOCHEMICAL CHARACTERIZATION OF THE BONE SPRING FORMATION, DELAWARE BASIN, USING CHEMOSTRATIGRAPHY AND INTEGRATED PETROPHYSICS
<p>The Delaware Basin forms part of West Texas's and New Mexico’s famous petroleum-generating Permian Basin. The Bone Spring Formation is a prolific hydrocarbon producer within this basin, creating one of the world’s richest oil shales. This formation has lithological sequences that are …

SYNOPTIC PATTERNS ASSOCIATED WITH NORTHEAST AND South east ice Storms
… travel. These synoptic systems involve deep isothermal regions where warm, moist air over-runs surface sub-freezing air. Much attention has been focused on Northeast ice storms, where a study by Cortinas et al. (2004) identified the Northeast as the region with the highest spatial distribution …

Species Distribution Modeling for Arid Adapted Habitat Specialists in Zion National Park
<p>The Arizona toad (<em>Anaxyrus microscaphus) </em>and Jones’ waxy dogbane (<em>Cycladenia humilis </em>var<em>. jonesii</em>) are habitat specialists with historical ranges in the desert southwest and specifically, Zion National Park (ZION). The machine learning method, MaxEnt, constructed …

Evaluating heat mitigation by urban canopy in New York City’s public housing developments
<p>This work forms one part of a larger investigation into the ecosystem services provided by urban canopy that aims to characterize the temperature reduction provided by urban forests and develop process-level understanding of vegetation response to heat waves in order to improve estimates of heat …

Sediment Provenance of Tsunami Deposits: Implications for Assessing the Relative Intensity of Paleotsunamis from the Sendai Coastline of Japan
<p>The 2011 Tohoku tsunami impacted the northeastern coast of Japan and caused unexpected damages due to the underestimation of this type of hazard. Of particular importance is the fact that geologic evidence for a predecessor event, the Jogan tsunami (CE 869), could have forecasted the severity of …

Comparative Lineament and Geomorphic Analysis of Chaotic Terrains and Noctis Labyrinthus, Mars
<p>Noctis Labyrinthus (NL) is an extensional trough network connecting the Tharsis rise and Valles Marineris on Mars. Chaotic terrains are a group of polygonally-fractured surface features commonly associated with subsidence due to rapid fluid loss within the subsurface. Polygonal surface patterns …

Identifying Key Factors Affecting Translational Landslides in Part of the Yakima Fold and Thrust Belt, Washington State
Washington has one of the fastest growth rates in the nation, and unfortunately also is among the most landslide-prone states. With increased population density and urban sprawl, the need for landslide hazard assessment grows. On the Columbia Plateau in central Washington, the smooth rigid, …

Parameter Identification And Fault Detection For Reliable Control Of Permanent Magnet Motors
<p>The objective of this dissertation is to develop new fault detection, identification, estimation and control algorithms that will be used to detect winding stator fault, identify the motor parameters and optimally control machine during faulty condition. Quality or proposed algorithms for Fault …

The Impact of Fe-Ti Oxide Concentration on the Structural Ridgity of the Lower Oceanic Crust, Atlantis Bank, Southwest Indian Ridge
<p>Fe-Ti oxides are important components of oceanic core complexes (OCC) formed at slow-spreading mid-ocean ridges since Fe-Ti oxides are more susceptible to crystal-plastic deformation than silicate minerals. This study investigated the predicted relationship between the presence and concentration …

Adapting to Extreme Heat: Social, Atmospheric, and Infrastructure Impacts of Air Conditioning in Megacities - The Case of New York City
<p>Extreme heat events are becoming more frequent and intense in most large cities. Built-up surfaces also limit cooling mechanisms, leading to warmer conditions in cities, a phenomenon called the Urban Heat Island (UHI). This presents major challenges to reduce adverse health effects of hot …

The Use of the Ostracode Cyprideis Americana (Sharpe) as a Proxy for Salinity in Bahamian Lake Systems
… of Cyprideis species in continental and other island settings. The valve Mg/Ca ratio and mean sieve pore circularity showed the best correlation with salinity and are the variables that will be most useful in paleosalinity studies from sediment cores. Future work should further …
