This thesis describes the design of a RISC architecture
for high speed data acquisition. The structure of existing
data acquisition systems is first examined. An instruction
set is created to allow the data acquisition system to serve
a wide variety of applications. The architecture is designed
to allow the execution...
The problem of estimating the parameters of a forced discrete
linear dynamic model is considered. The system model is conceptualized
to include the value of the initial state as a parameter. The forces
driving the system are partitioned into accessible and inaccessible
inputs. Accessible inputs are those that are measured;...
A simple analytical expression is developed to relate the energy required to initiate moist convection to boundary-layer properties. This expression and exploratory regression are applied to data from the National Hail Research Experiment to discriminate between environments leading to cumulus congestus and well-developed hail-producing thunderstorms in northeast Colorado.
In this...
Caissons are frequently used in the coastal environment for
breakwaters, jetties, seawalls, and piers. Because a satisfactory
analytical solution to a typical caisson installation has not been
developed, design of a caisson-style structure typically is either
based on physical model testing, which is expensive, or the
structure is designed as...
Three factors were found to be significantly correlated with the fluctuations and trends in silver salmon production in Oregon. Logging was found to adversely affect the runs of salmon in later years. Exceptional winter floods seem to produce poor resulting runs. Low summer water flows also appear to produce lower...
After three-quarters of a century of introduction of 152 conifer and broadleaf species,
no promising candidate exotic was found for the Douglas-fir region. Growth curves
spanning 50 years or longer are figured for many species. Firs, pines, larches, spruces,
hemlocks, and cedars originating in northwestern North America had superior growth...
Thermal oxidation of methyl oleate was studied over a range of temperatures from 50 C to 150 C for periods of time up to 30 min. Degradation was quantitatively followed by gas liquid chromatography (GLC) and liquid scintillation counting of the products of methyl oleate-U-14C heated under a stream of...
To consider the regional scale effects of forest management requires complete and consistent data over large areas. We used Landsat Thematic Mapper and Multispectral Scanner (TM and MSS) imagery to map forest cover and detect major disturbances between 1975 and 1992 for a 4.2 x 106 ha area of interior...
