When large disturbances occur in interconnected power systems, there exists the danger
that the power system states may leave an associated region of stability, if timely corrective action
is not taken. Open-loop remedial control actions such as field-forcing, line-tripping, switching of
series-capacitors, energizing braking resistors, etc., are helpful in reducing...
Lake-induced atmospheric circulations over three lakes ranging from 3 to 10 km width are analyzed using data from three aircraft during the 1994 Boreal Ecosystem-Atmosphere Study (BOREAS). A well-defined divergent lake breeze circulation is observed over all three lakes during the day. Under light wind conditions, the lake breeze is...
Common camas (Camassia quamash) is a culturally important wetland plant, used as a staple food source by many indigenous peoples of western North America for thousands of years. Camas populations were once widespread, but conversion of wetland prairies to agriculture has led to declines in suitable habitat. Edible camas bulbs...
Recent efforts in user-control of data-driven characters have focused on designing high-level graph data-structures that we call a Behavior Finite State Machine (BFSM). A BFSM is an interactive data-structure that benefits from the advantages of both motion graphs and blend-based techniques for generating animated motion. Each node in a BFSM...
Vernal pools are ephemeral surface water wetlands with unique hydrology, ecology and species composition. Rare and endemic species rely on vernal pool habitat due to specialization traits the species possess because they are adapted to the extreme conditions. Many vernal pool basins have been topographically and hydrologically altered and are...
The purpose of this study is to examine significant and persistent problems within the Salem-Keizer School District, particularly when comparing Douglas McKay High School to West Salem High School. Douglas McKay High School is one of the physically smallest schools in the district, with over 2000 students and has the...
Western juniper (Juniperus occidentalis) cover has more than doubled within the last century and currently occupies over 9 million acres in the Intermountain West. Encroachment has altered the spatial distribution of soil nutrients and plants in these systems, forming nutrient enriched 'resource islands,' under tree canopies. The purpose of this...
Seasonal wetlands in arid and semi-arid lands provide an important source of surface water in otherwise dry lands. Central Oregon's high desert, located in the Northern Great Basin (NGB) is dotted with hundreds of seasonal pools, locally called playas. The playas hold water or snow during parts of winter and...

The Pelton Round Butte Hydroelectric Project (Oregon) was built between 1957 and 1964. As a result the anadromous steelhead trout was extirpated from the upper Deschutes Basin by 1968. The Deschutes Basin is a model for instream flow restoration projects in the Pacific Northwest that are largely driven by the...
The Western Lake Survey (WLS) of 1985 documented the status of lake water chemistry across the western US and inferred population representations of various subregions and geomorphic units via statistically analyses. Results from this 1985 study indicated that lakes of the Oregon Cascades had the second most pristine and dilute...
