A weather station was established on the dock of the Oregon State
University Marine Science Center, Yaquina Bay, Oregon. A total of
197 weather observations was made from 30 June 1966 to 23 September
1966, with emphasis on the determination of the rate of evaporation
from an evaporation pan and...
Model testing has proven to be an effective tool in the study of
soil-structure systems. While primarily used in research work, this
method of evaluation is also applicable to the solution of many types
of complex design problems. Because of its workability and relatively
simple characteristics, sand is the most...
A wilderness area, as administered by the U. S. Forest Service, is a tract of undeveloped land over 100,000 acres in size with no roads or provision for motorized transportation. Commercial timber cutting, hotels, stores, and similar developments are prohibited. While there are some exceptions for private holdings and administrative...
Taking advantage of a favorable physical system but also risking the hazards of flooding, man has long occupied flood plain land. He has attempted to adjust rivers to his needs in order to reduce flood loss, but the rising cost of flood protection accompanied by an increase in flood damage...
This paper presents a theoretical study of real-time bandwidth
compression systems using the Hilbert transform and associated analytic
signal concept. An analytic signal is defined as
u(t) = s(t) + [superscript ¯]js(t) , where [superscript ¯]s(t) is the Hilbert transform of the signal
s(t). A complete discussion of the properties...
A brief history of X-ray control methods is presented, and
the instrumentation requirements and physiological considerations
pertaining to an automatic X-ray control system are discussed.
The latter half of the thesis describes the design and operation
of a device which will permit medical radiographs to be taken
automatically and at...
About 16 percent of Oregon's forest land is owned by the various
components of the forest industry. Most of this area lies within the
relatively heavily populated western portion of the state. These
factors, plus the fact that the public seems to have a peculiar attitude
about property rights when...
