This study conducts follow up research to my Mechanical Engineering Senior Project that was completed in March 2015. It follows the Student Powered Hydro and Entertainment Device (SPHED) as it is used in various middle school and high school classrooms. SPHED has three modules: a power generation module, a hydropower...
Application of automatic production techniques to the fabrication
of semiconductor devices has been somewhat limited by the requirements
of conventional alloying techniques. These alloying techniques
require an excessive amount of individual handling.
This thesis investigates the feasibility of applying percussive
welding to the fabrication of metal-semiconductor contacts, as a
solution...
The torsion test was evaluated as a method for determining the shear
strength of full-size structural lumber. The evaluation involved an experimental
length study, an experimental depth study, and a finite element study.
The length study consisted of fifty nominal 2x4 specimens, ten specimens
for each length, and ten American...
Wildfire is a largely terrestrial perturbation broadly recognized as an agent of disturbance and ecological change in forested biomes. Effects of post-fire conditions on biotic components of aquatic systems have been less well-documented, although hypothetically, the two are strongly connected. In fact, the influence of wildfire may be most profound...
During the early fall of 1998, I made contact with Therese Graf Tanalski
when I was searching for family members of deceased Hall of Fame
members. Therese grew up in Corvallis, attended OSU, and married a 1944
CE graduate, Theodore T. Tanalski.
During my conversations and correspondence with Mrs. Tanalski...
In the most recent decades, there has been extensive loss of seagrasses within the Indian River Lagoon estuary on the eastern coast of Florida. This decline poses a significant threat to the ecological function of the ecosystem, as well as to the social and economic wellbeing of the surrounding communities....
An analysis was conducted to test current theories
regarding education, income, and marital satisfaction as
determinants of parenting in different ways for men and
women. The gender specific issues in parenting to be tested
were: 1) Education is positively related to parental
involvement for both men and women. 2) Marital...
The purpose of the study was to investigate process and
stability issues in intermarried families utilizing data
from a group of American Indian intermarried families and a
group of endogamous European American families. Stability
issues such as marital satisfaction and overall problem
solving were investigated by comparing scores between the...
North American beavers (Castor canadensis) are ecological engineers that improve biodiversity and can improve the health of riparian ecosystems. Beavers are generalist herbivores with some evidence of species preference, utilizing woody material for both food source and dam construction. In the South Slough National Estuarine Research Reserve, Charleston, Oregon, a...
