Sound and Vibration Analysis of Alternative Rumble Strips

Creator:: Horne, Dylan Ross
Abstract:: Roadway departure crashes accounted for 18,275 fatal crashes in 2017 across the United States (Jones et al. 2017). Rumble strips (RS) provide audible and haptic interior alert when a vehicle is departing the roadway reducing run-off-the road crashes. Although inexpensive to install, and easy to maintain, RS are not installed...

An analysis of technical efficiency and productivity growth in the Pacific Northwest sawmill industry

Creator:: Helvoigt, Ted L.
Abstract:: The objective of this project was to investigate technical efficiency and productivity growth in the Pacific Northwest sawmilling industry over the period 1968-2002. Productivity growth was decomposed into three components: technical change, efficiency change, and scale efficiency change. In addition, using econometric methods, changes in output elasticities and input substitution...

The Team Size Paradox: Knowledge Transfer and Process Loss Effects on Team Formation

Creator:: Méndez-Vázquez, Yaileen M.
Abstract:: Teamwork has become a popular operational strategy applied as part of workforce management plans in manufacturing and service industries. Teamwork has been commonly used in organizations to pursue different goals such as increase business operations agility, boost company productivity, improve quality in operations, increase company flexibility, promote collaborative learning, hasten...

Non-destructive determination of yield stress for in-situ gusset plates

Creator:: Pflaum, Therese Michelle
Abstract:: Failure of a gusset plate that caused the I-35W Bridge collapse in Minneapolis, MN resulted in mandated rating of connections by the Federal Highway Administration (FHWA). Rating connections requires material properties as an input. The material properties are generally reported on the available detailed drawings for bridges. However, some bridges...

Balancing Timber Production and Conservation in the Oregon Coast Range: an Examination of the Response by Birds and Bird-induced Ecosystem Services to Forest Management at Multiple Scales

Creator:: Harris, Scott H.
Abstract:: Society derives many critical and irreplaceable values from forests. With a growing global human population and rates of consumption, forests are under increasing pressure to provide all these values simultaneously. To meet societal demands for wood products, tree plantations are becoming increasingly common and are replacing native forests. Yet, forests...

Estimating a juniper biomass supply from private rangelands : the impact of distance and biotic factors on costs

Creator:: McCaulou, Jeff C.
Abstract:: Central Oregon has attracted attention as a potential location for a biomass industry based on a locally fixed source of western juniper (Juniperus occidentalis Hook) feedstock. This study identifies a supply of juniper from private lands to determine how much of the available juniper is economically supplied at alternative prices...

Investigation of Iron Passivity and Chloride-induced Depassivation in Alkaline Electrolytes using Reactive Force Field Molecular Dynamics (ReaxFF-MD)

Creator:: Dormohammadi, Hossein
Abstract:: The corrosion and passivity of iron (and carbon steel) in media with different alkalinity as well as iron depassivation have been studied extensively using electrochemical methods and nano-scale surface characterization studies. The electrochemical techniques provide valuable information about the average electrochemical behavior of relatively large metal surfaces, typically in centimeter-square...

Environmental Impacts of Renewable Energy (solar and wind) on Water, Food and Energy Nexus

Creator:: Hassanpour Adeh, Elnaz
Abstract:: Rapid increasing of renewable energies and the knowledge about their environmental effects are very limited. As a result, the renewable energies (e.g. solar or wind energies) will play a vital role in the future because it is well accepted by environmental friendly industries. This dissertation presents the modeling, data analysis...

Evaluating safety at Oregon‘s isolated, high-speed, signalized intersections

Creator:: Kopper, Neil H.
Abstract:: Isolated approaches at signalized intersections with posted speed limits of 45 mph or greater generally experience large numbers of rear-end and angle collisions. A combination of less attentive drivers, high operating speeds, and less than ideal intersection characteristics can result in crash frequencies well above expected rates. A number of...

Thinning aged Douglas-fir : an analysis of mobilization costs and a log bucking strategy for revenue improvement

Creator:: Pilkerton, Stephen J.
Abstract:: Contract harvest operations have become the preferred approach to reducing the largest cost component of timber production through free market competition amongst logging contractors bidding or negotiating for work. The goal of this research was to investigate economic components of harvesting operations not previously studied for steep slope thinning harvests...
