Design techniques for radiation hardened-phase locked loops

Creator:: Nemmani, Anantha Nag
Abstract:: Spacecrafts experience radiation in the course of their operation and all electronic equipment on board these spacecrafts has to be designed to withstand the effects of this radiation. This thesis describes the effects of total ionization dose (TID) and single event transients (SET) in phase-locked loops - an important circuit...

Oscillators and phase locked loops for space radiation environments

Creator:: Vandepas, Martin
Abstract:: Circuits operating outside the earth’s atmosphere are more vulnerable to cosmic radiation and require special design consideration. The purpose of this work is to explore methods of mitigating the effect of radiation in phase locked loop (PLL) circuits. Several voltage controlled oscillators (VCOs) and two complete PLLs are designed and...

Phytoplankton shading of marine benthic macrophytes: Implications for intertidal community structure

Creator:: Kavanaugh, Maria T.
Abstract:: Previous observations of light levels and phytoplankton abundances along the Oregon coast demonstrated that phytoplankton attenuated light sufficiently to potentially limit the growth of intertidal macrophytes and therefore structure local intertidal communities. Inspired by this observation, in spring 2004, I initiated a study to quantify the direct and indirect benthic...

Vegetation response to prescribed fire in mountain big sagebrush ecosystems at Lava Beds National Monument, California

Creator:: Ellsworth, Lisa M.
Abstract:: Anthropogenic land use alterations such as livestock grazing and fire suppression have greatly altered sagebrush grasslands of the Great Basin, facilitating invasion of exotic annuals, increases in woody species, and losses of native species. Much of the current research surrounding wildland and prescribed fire in sagebrush dominated ecosystems has focused...

Monitoring fluoride pollution in Flathead National Forest and Glacier National Park, 1972

Creator:: Carlson, Clinton E. and United States. Forest Service. Division of State and Private Forestry
Abstract:: During August 1972, 15 vegetation plots monitered for foliar fluoride concentrations in 1971 were resampled near the Anaconda aluminum plant at Columbia Falls, Montana. Statistical analysis of the data showed that essentially the same amount of fluoride was taken in by conifers, shrubs, and grasses in 1972 as in 1971....

A cooperative evaluation of potential air pollution injury and damage to coniferous habitats on national forest lands near Colstrip, Montana : I. Interim report of activities from June 1, 1975 -- May 30, 1976

Creator:: Gordon, Clarence C., Carlson, Clinton E., Tourangeau, Phillip, and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: Baseline data for the first year of a two-year study to assess the current status of ponderosa pine stands in southeastern Montana relative to coal-fired electric power development are presented. Sixteen permanent plots in pine stands were established in eastern Montana, South Dakota, and Wyoming. Several characteristics believed to be...

Impact of copper smelter emissions on two subalpine ecosystems near Anaconda, Montana : preliminary report

Creator:: Walsh, Natalie, Bissell, Gael, and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: Preliminary analysis of data from this study in the mountains southwest of the Anaconda Copper Smelter, an industrial source of SO2 and heavy metal particulate, reflects a complex pattern of pollutant impact. The differential effect of smelter emissions on plant life in the study area is best explained by the...
