Several learning processes which can be used with computing
machinery are discussed in this paper. Consideration is given to what
has been done in this field in the past as well as to what is now
being done. New ideas which might be applied to such study are
introduced.

A PC based on-line advanced plant simulator (OLAPS)
for high quality simulations of Portland General
Electric's Trojan Nuclear Facility is presented. OLAPS
is designed to simulate the thermal-hydraulics of the
primary system including core, steam generators, pumps,
piping and pressurizer. The simulations are based on a
five equation model that...
The potential gains that could be realized from
optimizing timber harvesting are significant. To a great
extent it is these initial functions that dictate the
quality of future manufacturing steps. Timber harvesting
systems are defined by the operations they contain and the
equipment that perform them. For any given harvesting...
This paper addresses the problem of interactively modeling large street networks. We introduce a modeling framework that uses tensor fields to guide the generation of a street graph. A user can interactively edit a street graph by either modifying the underlying tensor field or by changing the graph directly. This...
The purpose of this paper is to explore the potential value of using a computer simulated systems dynamics model to address psychosis in mental illness. Psychosis is defined as a syndrome which is associated with many mental disorders, not a specific disorder itself. Psychosis generally produces delusions and hallucinations and...
Magnetic and gravity modelling was completed along two E-W transects offshore central Oregon. These models indicate that the backstop-forming western edge of the Siletz terrane has a seaward dip of approximately 40° to 49° at 44°48'N, shallowing to ~28° at 44°1 1 'N. This is a well-determined result, given available...
This study was undertaken to evaluate the spatial and temporal characteristics
of riparian groundwater tables adjacent to beaver ponds. The research was
conducted in two parts; in the first portion a two-dimensional, finite-difference
computer model was developed and utilized to simulate groundwater elevations
through time in pond-adjacent aquifers. Two types...
The planning of harvests and management activities for forested lands has traditionally been done with either binary search or linear programming. Since both these techniques have some advantages over the other, they have remained in wide use. Hoganson and Rose (1984) have suggested a technique that theoretically could overcome some...
This paper corrects an apparent deficiency in the published
information concerning Hardware Description Languages (HDLs) by
introducing and discussing an approach for selecting an HDL for
use in a design project. Although three classes of HDLs are discussed
in this paper, High-Level Languages (HLLs), General Purpose
Simulation Languages (GPSLs) and...
In this thesis an introduction to simulation and object oriented programming discusses the need for the creation of several classes which directly support object oriented simulation. The author places no restrictions on the type of simulations that can be conducted and simulation practitioners will find that the classes provided lay...
