This thesis describes research to implement a Bayesian belief network based
expert system to solve a real-world diagnostic problem troubleshooting integrated
circuit (IC) testing machines. Several models of the IC tester diagnostic problem
were developed in belief networks, and one of these models was implemented
using Symbolic Probabilistic Inference (SPI)....
Furrow irrigation is the dominant practice for irrigating row crops in the
western Treasure Valley region near Ontario, Oregon. Though improvements
have been made in management practices over the years, excessive runoff and
deep percolation are still important problems contributing to surface water and
Field observations were made...
The consumptive water use of six cities in the Willamette
Basin of northwestern Oregon was evaluated for the period 1960-66.
Consumptive use ratios were obtained by analyzing data from monthly
water supply and sewage flow records. The average annual consumptive
use for the six cities was found to be 26...
This thesis describes the application of Bayesian networks for monitoring and
diagnosis of a multi-stage manufacturing process, specifically a high speed production
part at Hewlett Packard. Bayesian network "part models" were designed to represent
individual parts in-process. These were combined to form a "process model", which is a
This publication provides information on the timing and pattern of biomass accumulation and nitrogen (N) uptake for a variety of Pacific Northwest crops. You can
use this information to schedule N fertilizer applications for maximum efficiency. To achieve near-maximum crop yields, an adequate supply of available N must be present...
In his July 31, 1996 remarks on welfare reform, President Clinton signaled his intent to sign into law the Personal Responsibility and Work Opportunity Reconciliation Act (PRWORA), bipartisan legislation aimed at reforming federal welfare policy. During the press conference, Clinton framed welfare as necessary but ultimately temporary relief, stating its...
Changing demographics in Oregon, accompanied by a rising Latino population, serve to dispel myths that we live in homogeneous, monolithic communities. Migration studies indicate migration is reshaping communities, contributing to ethnic diversity thus challenging our notion of identity and culture. Through the medium of oral histories and ethnography, this study...
