A method of improving power system transient stability using controllable parameters

Creator:: Mittelstadt, William Andrew
Abstract:: Controllable parameters in a power system include generator terminal voltage, generator input power and network admittances. These parameters can be controlled to damp mechanical rotor oscillation in the generators and thereby improve system transient stability. Explicit equations are derived in this thesis for the control of these parameters to introduce...

The design and construction of an ionization chamber to measure background radiation

Creator:: Weaver, Kenneth Earl
Abstract:: An ionization chamber was constructed, using a fiberglass wall sphere, for the purpose of measuring background radiation. The system consists of the fiberglass wall chamber, 38.85 liters in volume, air filled, not sealed, used in conjunction with a precision capacitor, nulling voltage supply and electrometer. It was calibrated against a...

Effect of dimethyl sulfoxide on nutrient digestibility

Creator:: Tancred, Barry John
Abstract:: Workers with dimethyl sulfoxide (DMSO) in the United States and England have reported in the literature that the chemical affects the weight gaining ability of experimental animals. Narula, University of Oregon Medical School, Portland, found that 50 parts per million DMSO increased the size and numbers of tissue culture cells....

Geology of part of the northeast quarter of the Mitchell quadrangle, Oregon

Creator:: Patterson, Robert Lynn
Abstract:: The thesis area covers 165 square miles including the greater part of the northeastern quarter of the Mitchell quadrangle in north-central Oregon. The three stratigraphic units exposed in the area consist of a variety of Tertiary volcanic rocks including the Clarno Formation, the John Day Formation, and the Columbia River...

An investigation of the distribution of Nephtys caecoides in Yaquina Bay

Creator:: Morrison, George Edwin
Abstract:: A study was undertaken in Yaquina Bay, Oregon during the summer of 1964 to determine the distribution and the factors affecting the distribution of the polychaete worm, Nephtys caecoides, Hartman, 1938, in the estuary. This organism has a continuous distribution from offshore to a point approximately eight kilometers into the...

Choice behavior as a function of memory in preschool children

Creator:: Glim, Margaret Ellen
Abstract:: The purpose of this study was to investigate the memory factors associated with preschoolers' performance in a two-choice, uncertain outcome decision situation. Choice behavior was examined under two conditions: one, (NMA), in which the child was required to rely on his memory to establish an appropriate prediction of the occurrence...

The utility of a correct choice under conditions of verbal reinforcement

Creator:: Nayak, Sheela Ramesh
Abstract:: The purpose of this study was to test Siegel's utility model of choice behavior under conditions of verbal reinforcement, in a nursery school population of both sexes. Two major hypotheses were tested: The ordinal hypothesis stated that under conditions of increased value of the payoff subjects' stable-state strategies will occur...

The effect of seeding rate on yield and yield components of two winter wheat varieties

Creator:: Rana, Prakriti Shumshere Jung Bahadur
Abstract:: Wheat is an important cereal crop in the Willamette Valley of Oregon and the stiff-strawed, high-yielding varieties are the predominant types grown. Observation of the effect of seeding rates on the yield and yield components are useful in determining which of the components contributes most to the yield of a...
