The doubly-excited machine can be used as a variablespeed
generator or as a variable-speed-drive motor. In
this thesis the focus is on the aspects associated with
generating electric power (real and reactive) from erratic
energy resources such as water or wind. In such cases,
the power input to the prime...
A time-domain model was developed to predict the fluid/structure
interaction of a three-dimensional deformable body in a fluid domain subject to
long-crested finite amplitude waves. These nonlinear waves induce transient
motion in the body. In turn, the interaction of the body with the waves modifies
the wave field, causing additional...
Five winter wheat cultivars and their diallel crosses were evaluated for plant height, harvest index, deading-maturity duration, the components of yield, (spikes per plant, spikelets per spike, kernel weight and kernels per spikelet)and total plant yield. Two diverse locations, Moro, a dryland site (250 mm annually) located in central Oregon...
Coal continues to be burned by direct combustion in packed or moving bed in
small size domestic furnaces, medium size industrial furnaces, as well as small power
stations. Recent stringent restrictions on exhaust emissions call for a better
understanding of the process of combustion of coal in beds.
The present...
This study seeks to determine the feasibility of
utilizing one vaporizable copper compound - bis-[1-
(dimethylamino)-2-propanolato] copper(II) (Cu(DMAP)₂ as a
potential wood preservative. The synthesis of Cu(DMAP)₂
was conducted in accordance with a method developed by
Buhro and Dingman, Washington University, St. Louis,
Missouri. The yields of Cu(DMAP)₂ synthesis were...
The object of this research study is to investigate and provide
some fundamental information about bed slumping in a partially defluidized
bed combustor. Due to the difficulty in making measurements and
observations at high temperature, a dynamically similar cold phase
fluidized bed was used to model the high temperature case....
With the rapid increase of the world energy demand and
consumption, the method and techniques to analyze, improve
and optimize energy conversion systems have to deal not only
with direct fuel exergy (energy) consumption, but also with
other resources, which have associated exergy consumptions,
and with environmental impacts, such as...
The internship I performed was with Rural Community Development Program (RCDP), a domestic non-governmental organization in the country of Nepal. This organization focuses on community development goals in rural communities, utilizing the efforts of volunteers within the context of environmental conservation ideals. I primarily worked with the associated community plant...
Competitive bid sales of U.S. Forest Service in the Pacific Northwest
timber resources have significant effects on the economies of
Oregon, Washington, and Idaho. These sales contribute to the economic
vitality of small regions or communities dependent upon timber as a primary
resource input. Any changes in the price or...
