Vertical Axis Pendulum Wave Energy Converters (VAPWECs) are thought to be both effective and robust at converting ocean wave energy into usable electricity. Seeking to build upon and investigate such potential, this work examines the merits of actively controlling a generic VAPWEC's pendulum for the purpose of increasing the converter's...
Ocean wave energy is a new and developing field of renewable energy with great potential. The energy contained in one meter of an average wave off the coast of Newport Oregon could supply dozens of homes with electricity. However, ocean waves are usually quite irregular which leads to large bursts...

In the Blue Mountains of northeastern Oregon, prescribed fire and mechanical harvesting economics were investigated for fuels reduction and forest restoration. Using a cut-to-length harvesting system, three single-grip harvesters and three forwarders produced significantly different production rates. For the harvesters, significant variables that affected production rates were found to be:...

This is an exhibit made by the Oregon Department of Fish and Wildlife before a meeting of the Oregon Fish and Wildlife Commission. It concerns the need for a uniform system of identifying crab pot buoys to help law enforcement.
It is generally assumed that multi-species fleets operate in a generalist
fashion, given diversity of gears employed. An analysis of gears, species

are indeed common in these types of fleets. In this paper we examine the
fishing operations...
