A project funded by the Southern California Edison (SCE) Company, Research
Center of Irwindale, California, has supported the development of a performance and
parameter prediction software program for use during the refurbishment of large
synchronous machines, turbine generators, and synchronous condensers. The computer
program was developed for SCE to allow...
The Horsetail Creek Bridge (HCB), constructed in 1914, is located along the Historic Columbia River Highway in Oregon. The original cross beams from the HCB were substantially deficient in shear strength, particularly for the projected increase in traffic loads. One control beam and three beams with varying configurations of a...

The Horsetail Creek Bridge (HCB), constructed in 1914, is located along the Historic Columbia River Highway in Oregon. The original cross beams from the HCB were substantially deficient in shear strength, particularly for the projected increase in traffic loads. One control beam and three beams with varying configurations of a...
This study defines the information gathering and communication and response
needed for safety at highway-rail crossings. It examines technologies for low-cost,
high-safety treatments for low volume highway crossings of higher speed (130-200 kph) rail. Crossing closure and consolidation is a necessary first step. Existing
train control and crossing safety systems...
Landslide processes occurring on a hillslope in McDonald-Dunn
Forest on the eastern slope of the Oregon Coastal Range are
described in terms of type, magnitude. minimum age and site
characteristics. Debris flows and debris avalanches are the
dominant types of slope movement occurring in the study area.
Landslide events classified...
Attempts to map the distribution of acidic
deposition have been inadequate, particularly in areas of
seasonal or limited rainfall. Ambient air concentrations
of acid precursors may be used to monitor and map the
distribution of potential acidic deposition. A network of
stations in California currently monitor these ambient air
concentrations....
Throughout Europe, Northern Africa, and the Near East, hundreds of Roman ruins lie scattered about. Many Roman aqueducts, bridges, roads, and even buildings remain standing over two thousand years after their construction, as functional as the day they were built. In the modern United States, however, many public works projects...

The Washington State Department of Natural Resources' Comprehensive Tree-Volume Tarif Tables are a set of preconstructed local volume tables. This can increase "on plot" efficiency since only diameters are necessary to obtain volumes after the proper table for the given diameter/height relationship is accessed. The tables are accessed and indexed...
