Design-approach evaluation of multiple-input, model-reference, adaptive control systems

Creator:: Cowgill, Paul Nelson
Abstract:: The model-reference, adaptive control concept is based on the precept that desired control system performance is a known design requirement and can be obtained from a representative model. Control system parameters are adjusted by the adaptive controller through a minimizing operation on a function of the error (i.e., performance index)...

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....

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...

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...

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...

Pheromonal communication in the western cherry fruit fly, with particular reference to oviposition

Creator:: Mumtaz, Mohammad Moizuddin
Abstract:: Studies conducted with the adult western cherry fruit fly, Rhagoletis indifferens Curran, revealed that successful oviposition occurred in three distinct phases, the prepenetration phase, the penetration phase and the postpenetration phase. During the postpenetration phase which averaged 51 seconds (range 18 to 86), the females dragged their ovipositor over the...

Calling behavior of band-tailed pigeons in reference to a census technique

Creator:: Sisson, Leonard Harold
Abstract:: Calling of captive and free-living band-tailed pigeons (Columba fasciata, Say) was studied between June, 1965, and June, 1967, in western Oregon. Vocalizations of captive band-tails were observed during mornings and afternoons in 1965 and 1966; calling of free-living band-tails was observed in mornings during call-counts and point observations in 1966....

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...
