12 Jamison, Ryan DaleAerothermoelastic modeling of hypersonic vehiclesOver the last few decades, aerothermoelasticity has become an ever increasingly important area of study. This has been most notably influenced by the development of hypersonic aircraft that surpass Mach 3. At such speeds, the elastic response of an aircraft to the aerodynamic heating and loading bec...Hypers; Fluid-structure interaction2008-12
13 Jia, YunluParticulate formation from pulverized coal under oxy-fuel combustion conditionsAerosol particulates are one of a variety of products generated by coal combustion. The objectives of this study were to elucidate ash particulate formation during oxy-fuel pulverized coal combustion compared to O2/N2 combustion. Oxy-fuel coal combustion conditions provide exhaust gas with a high co...Coal; Combustion; Oxy-fuel; Particulate formation2015-08
14 Lodder, Michael AlanBiologically motivated predictions for dynamic power in VLSI circuitsAs Very Large Scale Integrated (VLSI) circuits continue to shrink in size and increase in complexity, device design is increasingly power constrained. Currently, engineers must design their chips and then perform lengthy simulations in order to generate accurate power estimates. Once power predictio...Integrated circuits2008-12
15 Orr, Joseph AllenAn Anesthesia alarm system based on neural networks.The alarms in most patient monitoring devices are threshold alarms that call attention to the value of a single measured parameter. These threshold alarms do not aid in diagnosis and tend to have high false alarm rates.
