Seismically-induced liquefaction represents a major cause of damage to civil infrastructure and can result in significant damage following major earthquakes. Liquefaction can occur when earthquake ground motions raise pore-water pressures in loose, sandy soil, resulting in a substantial decrease of soil strength. Owing to the potential for instability following liquefaction,...
The use of high strength steel reinforcement has the potential to provide economic and constructability benefits when used in reinforced concrete structures. However, more research is needed to justify and confidently allow its use. Current design provisions limit the nominal yield strength of reinforcing steel bars to 60 ksi (420...
In computer science, learning abstract fundamental programming concepts requiring students to understand memory management can be very difficult and lead to misunderstandings that carry on into advanced topics. This is especially true in data structures with abstract data types. Understanding how novice students think and reason about data structures is...
Pine Creek Conservation Area (PCCA), just northeast of the John Day River in Wheeler County, Oregon, was acquired in 1999-2001 by the Confederate Tribes of Warm Springs with support from the Bonneville Power Administration (BPA), to mitigate for wildlife losses created by the large, hydropower Columbia River Dams, particularly the...
This research employed both quantitative and qualitative research methodologies to
explore the impact of mobile wireless technology (MWT) in higher education classrooms.
The methodology was developed using systems engineering concepts. A methodology to
evaluate and compare the cost, cost-effectiveness and cost-utility of different MWT
configurations was also developed. Five outcomes...
This publication consists of reports of projects carried out by
students in the Marine Resource Management Program in the School of
Oceanography at Oregon State University. These studies, sponsored by
the OSU Sea Grant Program and the School of Oceanography, were carried
out during the period 1974 to 1980. The...
