Creator:: Crispo, Richard F.
Abstract:: This research introduces an energy storage system to deliver microgrid frequency response. A doubly-fed induction generator (DFIG) and a squirrel cage induction machine (SCIM) are coupled together as a motor/generator set to deliver an immediate inertial response to a change of frequency, and an inverter and supercapacitors deliver short term...

Creator:: Hilliard, Richard F.
Abstract:: Anammox (anaerobic ammonium oxidation) bacteria are capable of providing low-cost nitrogen removal for numerous types of wastewaters. However, low growth rates cause long startup-times and inhibition by oxygen and metabolic substrates necessitate close process control to maintain performance. Incorporation of Simultaneous Anammox and Denitrification (SAD) into constructed wetlands could provide...

Creator:: Dyhrman, Richard F.
Abstract:: The thesis area is located southwest of Portland, Oregon, in the Western Cascades. In the area are volcaniclastic rocks and lava flows that range in composition from basaltic andesite to dacite. The dominant volcaniclastic rock type is thin intracanyon ash-flow tuff. The dominant lava flows are a thick sequence of...
