Task Grapher is a tool for the study of optimal parallel program task scheduling on arbitrary interconnected parallel processors. Given a task graph, this tool can be used to produce several kinds of displays to help users to determine optimal scheduling heuristics and optimal machine topology.

Oregon SpeedCode Universe (OSU) is a rapid prototyping system which automates the production of applications from a description of the user interface. GraphLab is a domain-specific tool which deals with several major problems concerning OSU: (1) limited functionality, that is, lacking graphical capabilities in generated applications, (2) indirect approach to...
The purpose of this project is to study the benefit at large parking lots having shuttle busses by providing a system that dynamically routes a shuttle. The shuttle route will be set by the placement of the travelers returning from the terminal. A parking space is assigned to the incoming...
Equal value gray scales are frequently employed by cartographers to choose gray tone area
symbols. Several researchers have tried to quantify perceived gray tone as a function of percent area inked or
reflectance but results have varied. The influence of pattern and texture on gray tone perception is considered
a...
Past disasters such as mercury poisoning in Minimata, and new problems such as tributyltin impacts on shellfish have maintained public concern about problems caused by chronic discharges of hazardous materials into marine waters (Clark, 1986; U.S. Congress, 1987). However, hazardous chemical spills in coastal waters typically escape public attention. Unlike...
Slope-aspect is the compass direction of a slope at a particular location on a given
surface, and can provide a graphic tool for people who require an understanding of
the pattern of slope-aspect variation across a landscape. Slope-aspect maps can be
helpful for terrain analysis, watershed management, building site analysis,...
The main purpose of this research is
1. To analyze the terrain/climate of Cape Verde, with emphasis on cloud
cover, and its effect upon satellite image acquisition.
2. To use a methodology that allows the use of AutoCAD to map these clouds effect in image acquisition to permit viewing whatever...
This research has focussed upon both the in vitro and in vivo characterization
of the recycling pathway leading from 5'-deoxy-5'-methylthioadenosine
to methionine in fruit. In addition to contributing towards polyamine
biosynthesis and other important cellular functions, in plant tissues
these events also serve to generate the hormone ethylene. A broad...
The utilization of ⁷⁷ [superscript m] Se, half life 17.5 s, and ⁷⁵ Se, half life 119.8 d, for quantification of trace amounts of Se in well water and biological materials by means of instrumental neutron activation analysis (INAA) is described. A Se detection limit of 0.03 ppm was achieved...
This paper presents data obtained in the study of an
18-wheel western type log truck outfitted with CTI and carrying a highway load. Operating on grades of 20 and 25 percent, drive shaft torque was monitored to quantify stress levels on the drive train while varying tire deflection. This paper...
The use of edible coatings in combination with antimicrobial
agents enhances the microbial stability of foods. In this study we
evaluated the potassium sorbate and sorbic acid permeability of an
edible methylcellulose (MC) - palmitic acid (PA) film with a MC:PA
ratio of 3:1.
Permeability cell measurements were used to...
An aspect of the genetic structure of coastal Oregon steelhead was
explored and found to gradually change in a north to south pattern for the
allelic frequencies of several enzymes. Isocitrate dehydrogenase and
superoxide dehydrogenase were the clearest examples of this pattern of
variation. This pattern was most evident in...
Tourism has become an important factor in Oregon's and
New Zealand's economies. Both destinations are trying to
attract even more tourists. However, many other destinations
are also competing for a bigger share of the tourism market.
Tourism itself is a multi-faceted phenomenon and the travel
destination decision is of some...
Dietary guidelines recommend that Americans consume no
more than 30 percent of energy intake from fat. The most
recent national survey reported that U.S. women consume
about 36 percent of energy from fat. Very little is
presently known about the fat intake, or food sources of
fat in the diets...
More Americans are participating in sport every year
and several organizations have made it their mission to
provide the opportunity for organized sport participation.
College and University intramural departments are one of
those organizations. They provide participation
opportunities on nearly every college campus. The review of
literature identifies the sociological...
This thesis reports on research conducted to determine
the information which should be included in a mechanical
design history. This is part of a larger research effort
aimed at developing a computer tool for storing and
replaying mechanical design history information. Three
question-asking protocols were conducted to determine what
information...
Sodium dodecyl sulfate polyacrylamide gel electrophoresis and
zymography were used in two separate experiments to determine the tissue
source and type of plasminogen activator (PA) produced by bovine
blastocysts. Twelve-14 d blastocysts were collected at slaughter from
estrous synchronized, superovulated and artificially inseminated Holstein
cows. In Experiment I, blastocysts were...
Norflurazon [4-chloro-5-(methylamino)-2(3-(trifluoromethyl)
phenyl)- 3(2H)- pyridazinone] and prodiamine (N3, N3-di-n-propy1-2,4-
dinitro-6-(trifluoromethyl)-m-phenylenediamine) are two herbicides
being considered for weed control in alfalfa. Rotational crops
following alfalfa may be sensitive to residues of these herbicides.
Studies were conducted in Oregon and Washington to examine the soil
persistence and activity of these herbicides on...
