Visitors to waterways need a way to securely lock up their non-motorized watercrafts to allow for exploration of the local area and communities. The Willamette Water Trail Steering committee recognized this problem and approached the Oregon State University Prototype Development lab to develop and fabricate a solution. The engineering design...
Unmanned Aerial System (UAS) technology is a rapidly developing technological marketspace. This thesis focuses on micro, tethered, coaxial UASs and the development of an electrically-tethered observation platform (ETOP). The thesis details the current status of the technology as well as current products on the market. Stability considerations, critical when adding...
"The literature that has been produced in the
South springs from the depth and fullness of the southern nature; it is all picturesque, in one manner or an
other. Creative art is everywhere evident, especially
in the works of Edgar Allan Poe. The works of George
Washington Cable receive vitality...
During the past year the rapid increase in the cost of copper and aluminum has led operating companies to investigate the feasibility of using iron and steel conductors for transmission and distribution purposes where small blocks of power are to be served. This Thesis gives the results of tests on...
The women of the past ages have made little progress
in literature, and many are those who have ascribed
it to lack of talent which is evident in the gentler sex;
but more agree with Eliza V. Farnham when she says, "I
will yield to none in the grateful admiration...
Currently, there is no accurate, low-cost method to track divers. Watching bubbles can
give you an approximate xy-location, and expensive underwater radios utilizing ultrasonic waves can work if the diver knows where they are. Traditional radio waves do not work well in water due to the conductive nature of water....
Slowly and half-heartedly the people of America have come to atone for past neglect of a poet who, under painful circumstances, produced the most distinctive and original contributions to American literature. They realize that the follies of his unfortunate life can be put aside and the weight of criticisms let...
Reclaimed water is a key source in overall global water management and sustainability;
however, small concentrations of antibiotics in treated wastewater effluent threaten
induction of antibiotic resistance in naturally-occurring soil bacteria and pathogens in
irrigated soils. This type of chronic exposure has the potential to lead to more severe food...
An electrically driven propellant pump (HALE E-Pump) was analysed and tested to determine its viability for use in a bi-propellant launch vehicle for the High-Altitude Liquid Engine (HALE) student rocket team at Oregon State University (OSU). The pump, manufactured in 2022 by students in OSU machine shops, was hydrostatically tested...
Understanding how particles behave in detectors is a critical part of analyzing data from neutrino experiments. There are methods in place to track charged particles in scintillator material, but neutral particles such as neutrons are more difficult to characterize. The purpose of this project was to assess and calibrate methods...
As young as American Literature is, it has been found necessary to divide it into five periods, namely: First Colonial Period (1620-1689); Second Colonial Period (1689-1763); Revolutionary (1763 -1815); First National Period (1815 -1863). Though by courtesy called Literature, the first attempts at writing by our forefathers cannot properly be...
The scientific method applies hypothesis testing to material samples through experimentation, measurement, and data analysis, which produce representations—or features—that describe phenomena of interest. Biomolecular features come in numerous forms such as values, matrices, graphs, three-dimensional structures, trajectories, and molecular surfaces. Researchers have tested thousands of features related to protein molecules...
Chilean society has been changing rapidly for the last few decades during a time of rapid economic growth. Some sociological and economical analyses state that when a nation grows, inequality between the rich and poor grows too, leaving the poor behind. The Chilean economy is the most rapidly growing in...
Artificial collectives are useful for accomplishing tasks that require teamwork from multiple simple robots. Multiple robot and collective testbeds have been developed, yet none stay committed to leverage the local interactions, group size, and imperfect information assumptions that strengthen biological collectives. A review of the collective and multiple robot literature,...
A spectral fitting routine was developed to analyze X-ray emissions in neutron capture decay
processes that produce ¹⁹⁷Hg and ¹⁹⁷Pt. Through correcting for X-ray emissions, the
77.3 keV γ gamma ray intensities were analyzed. The thermal cross sections for the production of
¹⁹⁷Hg and ¹⁹⁷Pt were found to be 2088...
