The Northwest timber industry is in a transition to a smallwood harvest environment. As the Northwest moves to smaller average diameter stands log values have decreased and harvest costs have increased. In an effort to increase profitability, Northwest loggers are beginning to "mechanize". The profitable operation of a mechanized harvest...
A Brushless, Doubly Fed Machine (BDFM) attempts to combine the advantages
of conventional induction and synchronous types of electrical machines by its unique
architecture. The validation of BDFM designs in an actual test environment requires the
estimation of the BDFM model parameters from actual experimentation. Accurate values
for the parameters...
This thesis is a comparative study of the two processes of currency change that occurred in Ecuador in 2000 and in France in 2002. Although the background of these two countries and the motivations behind each currency change varied, Ecuador and France have experienced many similar outcomes. Each of the...
In this research, a novel shunt compensation scheme
design procedure is developed for unbalanced, untransposed
n-phase transmission lines. The main function of the
scheme is to reduce the effect of the capacitive coupling
on untransposed transmission lines to levels where successful
single-pole switching is assured. The analysis procedure
This thesis introduces a Brushless Doubly-Fed Machine (BDFM), stand-alone
generator system. Development of a BDFM current-forced model, along with the
analysis of air gap power distribution between the two stator windings and the rotor
circuit, pave the way for the characterization and analysis of stand-alone generator
The main disadvantage...
Rising human populations and climate change are putting increasing demands on our already-limited freshwater sources. In response to these concerns, homeowners and municipalities have been encouraged to replace turfgrass – a plant with relatively high irrigation needs – with drought-tolerant plants that do not require frequent irrigation. However, the many...
In the northwestern Gulf of Mexico there is a need for reliable water level
forecasts to facilitate safe commercial navigation, marine construction, and emergency
management. Though the low amplitude tides of the region can be predicted with
conventional harmonic techniques, frequent strong storms make accurate forecasts of
water levels difficult....
The objectives of this study are to revise and reformulate a
previous simulation model of the Calapooia River and proposed
Holley Dam project and to critically investigate the anadromous
fish enhancement function of the project.
The Corps of Engineers proposes a 145,000 acre-foot reservoir
for the Calapooia River at Holley,...
