We hypothesize that the extraordinary maneuverability and efficiency of bats in flight are in part due to the compliant nature of their wing structures. We utilize the parameters of bat bones measured by biologists to create a biologically inspired model of a flapping system consisting of a rotating hub actuator...
Engineers have long been inspired by nature's flyers. Such animals navigate complex environments gracefully and efficiently by using a variety of evolutionary adaptations for high-performance flight. Biologists have discovered a variety of sensory adaptations that provide flow state feedback and allow flying animals to feel their way through flight. A...
Prompt radiation accounts for 3% of the energy released in a nuclear blast. Simulating the prompt radiation will help identify the potential changes to the ambient temperature and pressure of air around the blast. The changes in ambient conditions may alter blast wave effects. The relationship between the energy deposition...
Variations in heat treatments have significant effects on the microstructure of tool steels. For CPM-M4 tool steel, the changes in microstructure and mechanical properties were observed based off of variations in temperature. Five heat treatments with constant exposure time and variable austenitizing and tempering temperatures were performed on samples of...
Spectroscopic ellipsometry (SE) is used to characterize amorphous and crystalline thin films of TiO2. Amorphous precursor films of TiO2 are deposited by radio frequency magnetron sputtering on fused silica and silicon substrates. Annealing the amorphous precursor films induces them to crystallize into either pure or mixed phases of the three...
One reading of the post-postmodern literary period argues that as formal aesthetics have (re)engaged with ethics there has been a concomitant move to treat literature as a space of ethical potential. Adam Kelly has called this attitude, when combined with the appropriation of certain metafictional and postmodern techniques, the “New...
Over 10,000 feet of marine and nonmarine Late Cretaceous sedimentary rocks are exposed within a 110 square mile area in northeastern Teton County, Wyoming. An additional 1400 feet of nonmarine Paleocene and Miocene rocks overlie these. Landslide deposits and Pleistocene glacial moraine cover over one-half of the area. The Late...
This thesis presents the results of an investigation into the measured and modeled
mass balance of the Collier Glacier, a small (0.70 km²), valley glacier located in the
Oregon Cascade Range (44° 10' N, 121° 47' W). Here we present mass-balance
measurements conducted for the 2009 and 2010 balance years...
Steens Mountain in SE Oregon is part of the northern Basin and Range Province,
and represents a horst tilted about 100 to the west that is bounded to the east by a high
angle, NNE trending normal fault. The minimum displacement is about 1200 m. Volcanic
rocks, exposed along the...
