The study evaluates performances of three multiple time series
(MTS) forecasting methods; investigates possible improvements in
MTS forecasting operations, and proposes a multiple time series
based forecasting system. Time series considered are finite,
linear, covariance stationary, and discrete.
Specific objectives for the thesis were: (a) conducting comparative
studies of MTS...
Sustainable management of planted forests requires maintenance of soil function
to promote 1) root growth; 2) storage and cycling of water and nutrients; 3) optimal gas
exchange; and 4) biological activity. Soil quality measurements can be used to monitor
short- and long-term changes in these soil functions, allowing managers to...
Of great benefit, but not limited to seafloor mineral
exploration, is a technique that fairly rapidly determines the
composition of a drilled vibracore (in a time comparable to the time
involved in obtaining the core). The rapid assessment is desired to
predict whether a given region warrants further exploration by...
This classification lists the native plant associations known to occur in Oregon, and includes both successional and climax vegetation types that were an important part of the presettlement landscape of Oregon. It serves as an index to the diversity, distribution and relative rarity of the state's native plant associations, and...
In A Portrait of the Artist as a Young Man, James Joyce used
the form or structure of his language to connote a meaning which
supported the content of the text. The elements of form he used
most often were sentence and paragraph structure, punctuation,
rhythm, and classical rhetorical schemes....
Flow separation is an important phenomenon in fluid dynamics because of the effect it has on lift and drag on immersed bodies. Areas of swirl within a separated flow region may have a distinct effect on the surface forces, modifying the lift and drag characteristics. A correlation between the passage...
Previous studies have utilized different techniques (e.g., contingent valuation and travel cost methods) to understand users and non-users willingness to pay for natural resources, including their use of recreation areas. These techniques enable the calculation of public support, demand, and potential revenue that may influence future policy, conservation methods, land...
This paper develops a count data model of target species and bycatch
production for an arbitrary number of species that handles correlation
between species and over time. The model is applied to a large observer
dataset for fishing trips taken from 1990 to 2008 for roughly 150 vessels
participating in...
Hard white winter (HVVW) wheat cultivars must have superior protein quality and consistent processing quality to be successful in the Asian market. New cultivars and management strategies are needed to produce HVVW grain for both bread and noodle applications from diverse environments in the US Pacific Northwest (PNW). This study...
