As broadband Internet becomes widely available, Peer-to-Peer (P2P) applications over the Internet are becoming increasingly popular. Such an example is a video multicast application in which, one source streams a video to a large number of destination nodes through an overlay multicast tree consisting of peers.
These overlay multicast-based applications,...
There is a continual interest in developing robust, flexible, durable, lightweight, waterborne polymer barrier coatings which are increasingly resistant towards both chemical warfare agents as well as an ever growing number of toxic industrial chemicals. In this study, barrier films were prepared with poly(vinyl alcohol) (PVOH) and varying amounts of...
This thesis focuses on the application of the cosmogenic nuclide Beryllium-10 (10Be) in an effort to better constrain the thickness history of the Fennoscandian Ice Sheet (FIS) at the Last Glacial Maximum (LGM) and into the Holocene, as well as begin to answer the long-standing question regarding the age
and...
Popular applications such as P2P file sharing, multiplayer gaming, videoconferencing, etc. rely on the efficiency of content distribution from a single source to multiple receivers. Most users of these applications are on the widely prevalent source constraint networks such as the Digital Subscriber Line (DSL) and wireless networks. Overlay multicast...
The microbial loop plays a crucial role in remineralization of organic matter and fuels recycled production in the aquatic environment. The capability of microbes to utilize particular compounds can be examined through their ectoenzyme (found outside the cell) activities using fluorogenic substrate analogs. These catalysts hydrolyze polymers otherwise too large...
Ultra-wideband (UWB) communication has emerged as a very promising
technology for short-range wireless applications, including
high-speed multimedia transmissions and sensor networks. UWB
system designs involve many different aspects covering analog and
digital processing, channel estimation and modeling, and
modulation and demodulation. Although UWB still faces many
challenges, significant progress has...
Recent catastrophic wildfires have forced the forest management community to develop new strategies for reducing forest fuels. Tightly spaced understory trees often create a fire ladder allowing surface fires to encroach into the crowns of overstory trees. This situation can lead to intensive, catastrophic, stand-replacement forest fires. Mechanical removal or...
An experiment was conducted with 27 multiparous Holstein and 27 multiparous Jersey cows to determine if nicotinic acid (NA) supplementation during the prepartum phase of the transition period decreases lipolysis and improves dry matter intake and to determine if Holstein and Jersey cows respond similarly to NA supplementation. Cows were...
Groundwater nitrate contamination is a well-documented issue in the Southern Willamette Valley (SWV) of Oregon, as a Groundwater Management Area (GWMA) has recently been declared. As a GWMA, groundwater nitrate monitoring must occur until regional concentrations are below 7 mg/L NO3-N. However, the presence of temporal variability can make it...
Heavy timber framing relies primarily on bracing to withstand lateral loads due to earthquakes and wind events. Bracing configurations in heavy timber framed buildings vary widely and include cross bracing, knee bracing, and other geometries. Many heavy timber frames constructed during colonial American times are still standing, exceeding the expected...
Remote areas are frequently homes to regional subpopulations of endangered green sea turtles (Chelonia mydas) and their essential habitat. Local communities are often the users and primary stewards of this valuable and charismatic resource. Recognizing this, a Hatohobeian community group in Palau has engaged in longterm monitoring and conservation management...
Stream temperature, as an important component of stream ecosystems, can be affected by forest harvesting through removal of riparian shade and changes in hydrology. Riparian Management Areas
(RMAs), as implemented through the current Oregon Forest Practice Rules, are designed, in part, to maintain stream temperature following forest harvesting. However, effectiveness...
The effects of alongshore variability in topography (banks and capes) and spatial variability in the wind forcing, including the wind-stress curl, on coastal ocean circulation are studied using a combination of observations and model simulations. Satellite sea surface temperature observations are used to describe the seasonal evolution of temperature fronts...
A study was made of the possibility of producing pulp of viscose rayon grade from three Chilean hardwoods, coigue, tepa, and ulmo. Unbleached pulps were made from the three woods by (1) the neutral sulfite semichemical process with and without steam prehydrolysis, (2) a water prehydrolysis-sulfate process, and (3) the...
The purpose of this study was to explore, from current Native American and Alaskan Native undergraduate students, what their experiences were as first year college students on the Oregon State University campus. In addition, it was important to learn how these experiences contributed to their success, satisfaction or dissatisfaction, and...
Growing emphasis on ecosystem and landscape-level forest management across North America has spurred an examination of alternative management strategies which focus on emulating dynamic natural disturbance processes, particularly those associated with forest fire regimes. This topic is the cornerstone of research in the Blue River Landscape Study (BRLS) taking place...
Satellite remote sensing is an effective tool for mapping snow covered area. However, complex terrain and heterogeneous land cover, due to vegetation and patchy snow cover, present challenges to snow cover mapping. This research compares two techniques for mapping snow covered area: binary and enhanced fractional snow cover mapping techniques....
Butterfly bush (Buddleja davidii), an ornamental native to China, is an invasive species in Oregon and many other areas. In Oregon, butterfly bush invades disturbed areas, particularly riparian areas. The Oregon nursery industry has the highest farm-gate value of all agricultural commodities and butterfly bush is a significant plant to...
This study examined the validity of the WA PPA process which was developed to assess teacher candidates for licensing purposes. Three validities were investigated using Messick’s view. Content validity was addressed using the raters’ judgment to
establish alignment between the WAC standards and the INTASC. Evidential validity refers to the...
Celiac disease, an autoimmune response triggered by the consumption of seed storage proteins of cereals, affects an estimated 1% of the human population. In the case of wheat (Triticum aestivum L.), one of the world’s most consumed cereals, alcohol-soluble proteins, the gliadins, have been identified as the allergy-eliciting agents. Previous...
