A model reference adaptive system for control of a flexible mechanical manipulator

Creator:: Lee, Byeung Kyun
Abstract:: For control of a flexible manipulator, the assumed- mode method is applied to the mathematical model of the model reference adaptive system. In the assumed-mode method, the flexible, continuous manipulator is described by a limited number of degrees of freedom. A modified model reference adaptive system is studied for direct...

Plant growth regulators and shattering control in cool-season perennial grasses

Creator:: Lee, Suk-Kyun
Abstract:: Shattering is a natural phenomenon of floret and spikelet disarticulation across abscission layers of the pedicel and rachilla, respectively, after seed maturation. Seed shattering in cool-season grasses and native grass species is an economic problem in seed production. This study was conducted to determine whether the use of the plant...

Managing woody biomass transportation for improved biomass economics

Creator:: Han, Sang-Kyun
Abstract:: With rising fuel costs and enhanced environmental concerns, the use of renewable energy has been steadily considered and widely expounded as a solution to the challenges of global energy security and climate change. The use of woody biomass, in particular, has received considerable attention for energy production due to the...

Terahertz imaging and spectroscopy of carbon-based and semiconductor nanostructures

Creator:: Tomaino, Joseph L.
Abstract:: This thesis will cover work that I have completed relating to the field of terahertz (THz) science. My work has consisted of generating tunable, narrowband THz pulses in a table-top optical setup and using both narrow- and broadband THz pulses to study various material systems. Broadband THz pulses were used...

New paradigms for understanding and step changes in treating active and chronic, persistent apicomplexan infections

Creator:: McPhillie, Martin, Zhou, Ying, El Bissati, Kamal, Dubey, Jitender, Lorenzi, Hernan, Capper, Michael, Lukens, Amanda K, Hickman, Mark, Muench, Stephen, Verma, Shiv Kumar, Weber, Christopher R., Wheeler, Kelsey, Gordon, James, Sanders, Justin, Moulton, Hong, Wang, Kai, Kim, Taek-Kyun, He, Yuqing, Santos, Tatiana, Woods, Stuart, Lee, Patty, Donkin, David, Kim, Eric, Fraczek, Laura, Lykins, Joseph, Esaa, Farida, Alibana-Clouser, Fatima, Dovgin, Sarah, Weiss, Louis, Brasseur, Gael, Wirth, Dyann, Kent, Michael, Hood, Leroy, Meunieur, Brigitte, Roberts, Craig W., Hasnain, S. Samar, Antonyuk, Svetlana V., Fishwick, Colin, and McLeod, Rima
Abstract:: Toxoplasma gondii, the most common parasitic infection of human brain and eye, persists across lifetimes, can progressively damage sight, and is currently incurable. New, curative medicines are needed urgently. Herein, we develop novel models to facilitate drug development: EGS strain T. gondii forms cysts in vitro that induce oocysts in...

The Use of Terrestrial Laser Scanning and Computer Vision in Tree Level Modeling

Creator:: Gabriel, Richard S.
Abstract:: Laser Scanning represents a new opportunity in forestry to effect meaningful change in the methods used for collection and analysis of inventory data. With the ability to collect spatial information in 360 degrees, while fluidly tracking the sensor and building the final point cloud, large tracks of terrestrial LiDAR based...

Modeling air-drying of Douglas-fir and hybrid poplar biomass in Oregon

Creator:: Kim, Dong-Wook
Abstract:: Both transportation costs and market values of woody biomass are strongly linked to the amount of moisture in the woody biomass. Therefore, managing moisture in the woody biomass well can lead to significant advantages in the woody biomass energy business. In this study, two prediction models were developed to estimate...

Local and Regional Patterns in Eelgrass (Zostera marina L.) Communities Along an Upwelling-Productivity Gradient in Oregon Estuaries, USA

Creator:: Motley, Jennifer
Abstract:: In this thesis, I investigate the organization of eelgrass (Zostera marina L.) and mesograzer communities across local and regional scales in three upwelling- influenced estuaries located along the Oregon coast, USA. Eelgrass ecosystems are an important source of primary production in estuarine systems, providing numerous ecosystem services, including nursery habitat...

Kinematic analysis of legged system locomotion on smooth horizontal surfaces

Creator:: Baek, Yoon Su
Abstract:: This thesis presents a model of legged locomotion in which position and velocity of body are directly controlled by positions and velocities of feet. One central relationship between foot acceleration, leg stroke and body velocity is developed. Procedures for determining all parameters of a step sequence including periods of constant...
