Ballast water discharges are a major source of species introductions into marine and estuarine ecosystems. To mitigate the introduction of new invaders into these ecosystems, many agencies are proposing standards that establish upper concentration limits for organisms in ballast discharge. Ideally, ballast discharge standards will be biologically defensible and adequately...
Species declines and extinctions have been recorded across taxa as evidence of an ongoing global biodiversity crisis. Amphibians are at the forefront of these declines with nearly one third of amphibian species estimated to be at risk of extinction. While many factors contribute to population declines and extinctions, the role...
In the Pacific Northwest snow is an important
natural resource. The inability to accurately measure or
monitor this resource throughout remote areas is a hindrance
to water management. ERTS-1 imagery provides the capability
for extracting a significant amount of scientific information
and data regarding snow conditions in accessible and inaccessible...

The ongoing worldwide loss of biodiversity has been described as a "biodiversity crisis," "the Anthropocene defaunation," and alternatively "an extinction spasm." More recently, many scientists have come to the conclusion that we are witnesses to Earth's sixth major mass extinction event, which has the potential to fundamentally alter basic ecological...
Technological advances of the last three decades have caused an enormous increase in the amount of published and unpublished information generated by our society. This inflation has created the need for improved information management systems. Existing systems are inadequate primarily because they are discipline-oriented and lack the flexibility that is...
Program comprehension is important in program testing, debugging, and maintenance. Programming style impacts program understanding. However, there has not been any systematic identification of individual style factors and their contribution to program comprehension. In this thesis we present a programming style taxonomy composed of three classes: typographic (program layout and...
The implicit Monte Carlo (IMC) method [16] for radiative transfer, developed in 1971, provides numerical solutions to the tightly-coupled, highly-nonlinear radiative heat transfer equations in many physical situations. Despite its popularity, there are instances of overheating in the solution for particular choices of time steps and spatial grid sizes. To...
