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....

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...

A Rhetorical Analysis of Feminist Critics' References to Virginia Woolf

Creator:: Stockton, Judith D.
Abstract:: Virginia Woolf wrote both prose and poetry, both fiction and non-fiction: she was both a creative writer and a politically conscious reporter. She left a wealth of beautifully crafted observations and comments that continue to be immensely quotable and influential. Feminist critics today use Woolf's vocabulary to continue the feminist...

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...

Comparison of dosimetric modeling of the International Commission on Radiological Protection trout reference animal

Creator:: Comolli, Michelle LeAnne
Abstract:: Radiation protection has historically been from a human protection approach, therefore many studies have neglected the potential dose contribution from the gastrointestinal tract (GIT) in animal studies. The International Commission on Radiological Protection (ICRP) utilized simplified geometric shapes with Dose Conversion Factors (DCF) based on homogenized models for the trout...

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...

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)...

Spatial relationships for vegetation in restored and reference salt marshes in the Salmon River Estuary, Oregon

Creator:: Chellew, Megan
Abstract:: In this thesis, the spatial patterns of vegetation and soils of reference and restored tidal marshes were compared to determine the extent to which restored sites differ from the reference site after 40 years of restoration. Vegetation surveys of 1m x 1m plots were conducted along previously-established transects of salt...

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...
