This thesis presents a design-oriented model for lightly doped CMOS substrates. The model predicts the substrate noise coupling between noisy digital and sensitive analog blocks in the early stages of the design. The model scales with the size and separation of these blocks and it is validated with device simulations...
A simple debris-slide model, employing a digital elevation model (DEM) and geological data, was used in a geographic information system (GIS) to map slope stability in the Andrews Experimental Forest, located in the western Cascade Range in Oregon, USA. To evaluate the contribution of error in elevation to the uncertainty...
A method is described for determining the partition coefficient, K, for radon gas
distributed between an aqueous phase and an organic solvent. The method uses
sequential extractions of radon into equal volume aliquots of organic solvent. The
radon-laden organic liquid is then counted on a liquid scintillation analyzer with alpha-beta...
β-SiC is a semiconductor for high temperature devices, which exhibits several outstanding properties such as high thermal stability, good chemical stability and wide band gap. There is a possibility of fabricating a crack-free ultrathin SiC film on silicon wafers by pyrolysis of polymethylsilane (PMS) film.
This study looks into the...
Previous work in this laboratory revealed that hormone analysis using fecal samples may predict the number of fetuses carried by pregnant ewes at mid- to late gestation. Reliable lambing number prediction is useful to the producer. Using gas chromatography/mass spectrometry the 5α- and 5β-series of pregnanes and selected 4- and...
Viability analysis of well-selected focal species can complement other types of conservation planning by revealing thresholds in habitat area and landscape connectivity that may not be evident from ecosystem-level evaluations. I used focal species analysis of five carnivores to suggest conservation planning guidelines for the Rocky Mountains and adjacent areas...
This dissertation addresses two topics on market imperfections. First, chapter
2 presents a theoretical model that focuses on problems associated with informational
asymmetry. The model presents a dynamic signaling game between a monopolist
manufacturer and a monopolist retailer, where demand is uncertain and only the
retailer is privately informed. This...
This document investigates, justifies, designs, and simulates the application of a fuzzy logic controller/optimizer in a sawmill bucking system application that is the first production station where stems coming from the mountains are processed in a sawmill. One of the areas of success in the application of fuzzy logic is...
This project aims at building a Java application and a Java applet that would simulate a Stern-Gerlach laboratory in Quantum Mechanics. The project provides a tool for allowing the student to quickly design and run on the computer screen a number of experiments involving spin systems. This application could be...
BIOMAP (Biogeochemistry model (BIOME-BGC) - Mapped Atmospheric Plant Soil System (MAPSS)) is a computer program that predicts ecosystem distribution and behavior over spatial grid cells of 10km at a daily timestep. It needs to consider events like fire for a more realistic prediction. This project involved integrating a new fire...
