A numerical analysis of ice fog produced by automobiles

Creator:: Nelson, William George
Abstract:: A model of an exhaust plume was developed and programmed on a digital computer. The purpose of the model was to predict the concentration and size distribution of ice particles produced from automobile exhaust during arctic conditions. The model accounted for the nucleation, growth, and freezing of the condensed water...

Temperature prediction using energy budget techniques on small mountain streams

Creator:: Brown, George Wallace, 1939-
Abstract:: This study is part of the Alsea Basin Logging-Aquatic Resources Study research program. It was initiated to determine the applicability of energy budget theory to stream temperature prediction on small forested streams. The study was also designed to evaluate the energy budget technique as a tool in the management of...

Measurement and interpretation of physical properties of soils

Creator:: Nagpal, Narender Kumar, 1942-
Abstract:: One of many important physical properties that must be known to understand transport phenomena in soils is pore size distribution. Presently the pore size distributions of soils are most commonly obtained from soil water characteristic curves. The soil water characteristic curves are usually obtained by the pressure plate technique. It...

Snowbrush, Ceanothus velutinus Dougl., its ecology and role in forest regeneration in the Oregon Cascades

Creator:: Zavitkovski, J.
Abstract:: The ecological and silvicultural importance of snowbrush, Ceanothus velutinus, in the areas west of the summit of the Oregon Cascades was studied. Particular attention has been given its nitrogen- fixing ability under both field and greenhouse conditions. On west slopes of the Oregon Cascades snowbrush occurs above 2, 500 feet...

Native bees, honeybees and pollination in Oregon cranberries

Creator:: McKenney, Melissa A.
Abstract:: Farmers rely almost exclusively on the imported European honeybee (Apis mellifera L.) for fruit and vegetable crop pollination services. The recent decline in honeybee health has underscored the danger of relying on a single species to provide vital services. Increasing pollinator biodiversity with native bees may provide biological insurance against...

Defining habitat preferences of pelagic loggerhead sea turtles (Caretta caretta) in the North Atlantic through analysis of behavior and bycatch

Creator:: McCarthy, Abigail L.
Abstract:: For many species of marine turtle the characteristics that define pelagic habitat have yet to be fully identified. A better understanding of these habitat characteristics is critical to reduce high seas fisheries interactions with turtles, especially as the status of many turtle populations has placed them on the threatened or...

Comparative foraging ecology of five species of Pacific seabirds : multi-scale analyses of marine habitat use

Creator:: Suryan, Robert
Abstract:: Seabirds are an integral component of marine ecosystems, however, because humans typically observe only snapshots of their lives at sea, our understanding of seabird foraging ecology is often limited. A more complete understanding of the ecological roles of seabirds and identification of critical foraging habitats requires the ability to follow...

Oxidation of Amorphous Metal Alloy Surfaces Studied Using Ambient Pressure X-Ray Photoelectron Spectroscopy

Creator:: Alzaga Elizondo, Pedro
Abstract:: Amorphous metal thin films (AMTFs) are of growing interest due to their unique mechanical properties and chemical stability. AMTFs have an advantage over polycrystalline metal films due to the lack of grain boundaries which gives AMTFs added durability and relatively smoother surfaces. For this reason, AMTFs have been investigated as...

Biomechanical Modeling of Isometric Muscle-Tendon Force Generation Through Tendons Coupled in Parallel and a Passive Differential Mechanism

Creator:: Le, Anthony H.
Abstract:: There are at least fifteen types of upper extremity tendon transfer procedures for combined peripheral nerve injuries that involve re-routing a single donor muscle to multiple recipient tendons. As a result, force and movement across finger joints become coupled, resulting in limited grasping abilities. Quantification and modeling of the donor...

Mental Models of Mere Mortals with Explanations of Reinforcement Learning

Creator:: Anderson, Andrew A.
Abstract:: How should reinforcement learning (RL) agents explain themselves to humans not trained in AI? To gain insights into this question, we conducted a 124 participant, four-treatment experiment to compare participants’ mental models of an RL agent in the context of a simple Real-Time Strategy (RTS) game. The four treatments isolated...
