This thesis presents my research on the hardware and software for
control of a novel robot based on the Stewart Platform. The robot has
six actuators which must be adjusted to arrive at the desired position
of the platform. This position must be specified by six position
parameters; namely the...
Water temperature in rivers and streams is an important factor for aquatic ecosystem health. Measurement of stream temperature has traditionally been accomplished by point temperature measurements, continuous point temperature loggers, and more recently, airborne remote sensing techniques such as Forward-Looking Infrared Radar (FLIR) or Thermal Infrared Radiometry. While each of...
Triticale, a newly man-made cereal from a wheat-rye cross offers a
unique food and feed potential because of its higher protein content
with nutritionally balanced amino acid composition as compared to other
cereal grains. However, some cereal proteins such as trypsin inhibitors,
present in triticale and rye, can affect the...
Nine feeding trials and four laboratory scale experiments were conducted in this study. The study consisted of: (1) use of grass straw:corn juice (CJ) silages with fishmeal and/or alfalfa hay supplementation in beef heifers, sheep, pregnant dairy heifers, water buffaloes and Hereford cows; (2) use of cull onions:grass straw silages...
Snags provide critical habitat for nearly one-third of wildlife species in forests of the Pacific Northwest, so historic declines in snags are thought to have had a strong impact on biodiversity. Resource managers often create snags to mitigate the scarcity of snags within managed forests, but information regarding the function...
Thirty-three genotypes of red fescue were selected on the
basis of diverse origin, anthesis date, and type of spreading from a
space-planted introduction nursery.
Open-pollinated, single-cross, and top-cross progeny
nurseries were established into a randomized block with four replications,
20, 9, 8 entries, respectively, with nine plants per entry
on...
Paleozoic limestones, dolomites, quartz arenites, and other
clastic rocks were mapped in the vicinity of Dobbin Summit and
Clear Creek in the central Monitor Range. Sedimentary rock units
present in this area represent the shallow-shelf eastern assemblage
and basin and also the basin-slope facies of the traditional limestoneclastic
assemblage.
The...
Soil erosion by mass wasting is the major problem on forest
lands of the Pacific Northwest, The clay fractions of soils from a
large number of sites in Oregon's Western Cascades were characterized
in order to determine the relationships of various clay materials to
mass movements. Each site was either...
The study involved three separate research efforts
in which 10 Holstein calves and 85 purebred Hampshire and
Suffolk ewe and ram lambs were employed. The objectives of
the experiments were to characterize appetite, describe its
inheritance and evaluate its associations with animal
performance.
In the calf experiment, appetite was determined...
