Adaptive model reference control of highly maneuverable high performance aircraft

Creator:: Collins, David C. (David Charles), 1969-
Abstract:: This thesis presents an adaptive model reference controller for a highly maneuverable high performance aircraft, in particular, a modified F18. An adaptive controller is developed to maneuver an aircraft at a high angle of attack. Thus, the aircraft is required to fly over a highly nonlinear flight regime. The adaptive...

Historical disturbance regimes as a reference for forest policy

Creator:: Thompson, Jonathan R.
Abstract:: Using the historical range of forest conditions as a reference for managing landscapes has been proposed as a "coarse-filter" approach to biodiversity conservation. By emulating historical disturbance processes, it is thought that forest management can produce forest composition and structure similar to the conditions that once supported the native biota....

Characterization and Biodegradation of Commercial Reference Material Capstone 1157

Creator:: Van Meter, Mariann I.
Abstract:: Capstone 1157 is a commercial reference material used in aqueous film forming foam (AFFF) applications and was manufactured by DuPont. The material’s purpose in this project was to be the sole carbon source to microbes in a biodegradation study in a microcosm environment. The goal of this project was to...

An ultra low power frequency reference for timekeeping applications

Creator:: Oporta, Hector Ivan
Abstract:: An ultra low power crystal oscillator that provides a frequency reference for battery powered timekeeping applications is presented. An amplitude control circuit is employed to ensure that minimum current is consumed. A subthreshold voltage regulator provides a supply voltage for the oscillator with minimum current consumption. The oscillator and regulator...

Economic comparison of structural design with reference to radiation shielding

Creator:: Rasmussen, William Kent
Abstract:: This paper investigates the proposed preliminary designs of two gymnasiums with respect to gamma radiation shielding due to radioactive fallout. For each building a determination is made of the protection offered from radiation fallout. If the degree of protection is below the minimum value set by the Office of Civil...

Effects of reference displacement and damage accumulation in wood shear walls subjected to the CUREE protocol

Creator:: Langlois, Jeffrey D.
Abstract:: The objectives of this study are: (1) to evaluate the effect of reference displacement on wall behavior under fully reversed cyclic loading using the CUREE test protocol and (2) to assess damage accumulation (visible fastener damage and stiffness degradation) for the imposed drift levels. All tests were conducted on identical...

Modeling of subthreshold current of GaAs MESFET and the design of voltage reference circuit

Creator:: Or, Pee-Keong
Abstract:: The characteristic of the subthreshold current in a GaAs MESFET exhibits a negative exponential function with Vgs. After studying the behavior of this current in this region over a range of temperature and drain bias voltages, a subthreshold current model was developed. The model was implemented in a circuit simulation...

Digital simulation of a vertical reference system incorporating random error sources

Creator:: Rover, Jack Terry
Abstract:: The vertical reference system being considered utilizes a two-degree-of-freedom gyroscope configured as a vertical gyro. Each gimbal erection circuit forms a second-order feedback control system. Gyros are susceptable to a number of error sources. In view of the closed loop application being considered, all error sources are of negligible consequence...

An Ecoregion-Based Reference Condition and Classification Scheme for Determining Nutrient Criteria in Oregon Lakes

Creator:: Brenner, Jacqueline M.
Abstract:: The anthropogenic introduction of nutrients to water bodies has been shown to alter the structure and function of natural aquatic ecosystems, yet national EPA lake and reservoir nutrient criteria remain too broad for effective regional water quality management. This study uses a reference site approach to propose numeric nutrient criteria...
