The Long Tom Watershed Council (LTWC) is a non-profit organization in Eugene, Oregon that serves to protect and enhance watershed health in the Long Tom River Basin. The Amazon Creek Initiative was launched by the LTWC in 2011 as Oregon’s newest Pesticide Stewardship Partner. Goals of the initiative are to...
Cross sections for radiative capture of neutrons have been measured by the activation technique for stable isotopes of Ba with mass numbers 130, 132, 134, 136, and 138. From separate irradiations using thermal and epithermal neutrons, independent values for the thermal cross sections and effective resonance integrals have been determined....
The purpose of this study is to explore experiences of professional growth for mid-career community college faculty. The research question that guided the study is: How do community college faculty members experience professional growth at mid- career? The research design included an interpretive social science methodology and phenomenological method. Nine...
A comprehensive and scalable solution for high-performance switched capacitor amplification is presented. Central to this discussion is the concept of ring amplification. A ring amplifier is a small modular amplifier derived from a ring oscillator that naturally embodies all the essential elements of scalability. It can amplify with accurate rail-to-rail...
Networks of distributed, remote sensors are providing ecological scientists with a view of our environment that is unprecedented in detail. However, these networks are subject to harsh conditions, which lead to malfunctions in individual sensors and failures in network communications. This behavior manifests as corrupt or missing measurements in the...
Clothing is the primary means that wilderness backpackers have to protect themselves from injuries and illnesses that can occur while hiking in the cold. The current method of layering clothing may not meet backpackers' needs for both thermal insulation and heat dissipation, particularly in areas of the body that produce...
The problem of determining whether a crack impinging on an interface will penetrate into the substrate or deflect along the interface is vital to the effective design of layered and composite material systems. Of particular interest is the transition between crack propagation by penetration through an interface and deflection along...
The Global Formula Racing (GFR) team is an organization of student designers at Oregon State University (OSU) and at Duale Hochschule Baden-Württemberg (DHBW) in Germany working to create two race cars to compete in international competitions through the Society of Automotive Engineers (SAE). The large scope of this project necessitates...
A cross-cultural analysis of business practices based on video recordings of interviews with business professionals in both Oregon and Taiwan, with the intent of finding evidence to support or question current beliefs about cultural differences between American and Asian cultures. Particular focus is paid to business practices such as networking,...
This thesis describes the design and implementation of a Bluetooth controlled blimp with autonomous capabilities through Dead Reckoning. Reasonable research was conducted on current autonomous systems, wireless communication techniques, and suitable microprocessors that could handle the required processing. Building a remotecontrolled blimp requires a light understanding of mechanics to build...
