This thesis presents the design of various controllers for a highly maneuverable,
high performance aircraft, namely the modified F-18. The aircraft
was required to perform high angle-of-attack maneuvers, for which the aircraft
behaves in as a highly nonlinear system. An adaptive PID controller
was used to control the aircraft through...
The effects of modifying air temperature, soil temperature,
and soil moisture levels on flowering, fruiting, and chemical composition
of Tendercrop snap beans were studied in experiments in
the field and in the greenhouse during 1961, 1962, and 1963.
High maximum temperatures of 95-105° F. during bloom reduced
the percent set...
Advances in technology such as 3D digital scanning and spatial analysis software have provided archaeologists with novel data. Specifically, these methods increase the researcher's ability to measure artifact morphology and past networks of cultural transmission, to potentially track the movement of past peoples and ideas through space and time. This...
Studies with fluorodifen were conducted to gain more information
about its field performance and the influence of light quantity,
quality and timing of exposure on its phytotoxic properties. Uptake
and trans location in three plant species were also investigated.
These studies were aimed at evaluating the usefulness of this chemical...
The severity of wildfires around the globe is increasing. At the same time, urban development is expanding outward into areas where severe fires occur. There is an increased risk of home loss to fires in areas where severe fires and urban expansion meet. Ignition of homes or nearby fuel is...
Chromium, an element of widespread use, is toxic in some
forms. Improper disposal of waste chromium products has
resulted in contamination of many sites throughout the United
States, including the United Chrome Products Superfund site
in Corvallis, Oregon. A better understanding of chromium
chemistry is needed to facilitate the remediation...
