Scientists and engineers have to analyze and query multiple large databases. Analysis over databases created by phasor measurement units can provide insight into the health of the grid, thereby improving control over operations. Realizing this data-driven control, however, requires validating, processing and storing massive amounts of PMU data efficiently, which...
The United States is a global leader in agricultural productivity. Much of its productivity growth can be attributed to public investments in agricultural research and development, starting in the 19th century and continuing until today. Past studies have shown high returns to agricultural research investments, but publicly funded agricultural research...
N-mixture models provide a structure for making inference about a local population size while accounting for imperfect detection. Using a binomial likelihood, they assume prior distributions on the size parameters and then integrate those parameters out of the full likelihood. For large population sizes, the established frequentist methods have exhibited...
Leads are long fractures wide enough for a ship to travel through the ice pack. Sea ice acts as a barrier between the ocean and the atmosphere, whereas leads allow the transfer of heat and moisture between the two. Leads play a role for marine mammals and are hunting grounds...
Recent studies have shown that there is a significant amount of dissatisfaction and
stress associated with finances, job security, and work. There are many health related
consequences that manifest in response to this continual stress that we experience in
our professional lives. These include obesity, high blood pressure, high cholesterol,...
The development of analytical methods for emerging contaminants creates many unique challenges for analytical chemists. By their nature, emerging contaminants have inherent data gaps related to their environmental occurrence, fate, and impact. This dissertation is a compilation of three studies related to method development for the structural identification of emerging...
This work presents improvements to a multi-core performance/power simulator. The improvements which include updated power models, voltage scaling aware models, and an application specific benchmark, are done to increase the accuracy of power models under voltage and frequency scaling. Improvements to the simulator enable more accurate design space exploration for...
Pacific lamprey, Entosphenus tridentatus, have shown recent and rapid declines in abundance. These anadromous fish return to streams where they mature, spawn and die. It has been inferred that Pacific lamprey enter freshwater and reside for ~ 1 year before spawning. This long exposure to the freshwater environment may affect...
Northern rock sole (Lepidopsetta polyxystra) is a commercially
important fish in the North Pacific and a
focal species in understanding larval transport to nursery
grounds in the Bering Sea. However, the temperature-dependent vital rates and settlement dynamics for
this species have not been described in detail. We
reared northern rock...
Sea otters fulfill a keystone role in several Northeastern Pacific nearshore ecosystems. However, their influence has been absent in Oregon coastal waters since their extirpation in the 19th and early 20th century. Interest has been growing for a translocation attempt to reintroduce sea otters to Oregon from one or more...
