Stephens winter wheat was grown using conventional furrow irrigation and surge irrigation on 12 one-half-acre plots. Both systems were operated simultaneously four times during the season. Conventional irrigation applied 26.5 ac-in/ac of water with runoff of 0.8 ac-in/ac and infiltration of 25.7 ac-in/ac. Surge irrigation applied 13.7 ac-in/ac with 0.5...

Fires set by Native Americans were important in shaping and maintaining Willamette Valley prairie plant communities. With fire exclusion after Euro-American settlement in the 1840's, composition of the remaining prairies shifted toward shrub and tree dominance with a concomitant decline in endemic prairie plant populations. I hypothesize that by restoring...
This thesis examines forest history of a portion of the Douglas-fir Region: Soap Creek Valley, a 15,000 acre sub-basin of the Luckiamute River in northern Benton County, Oregon. The primary reasons for the research were to test oral history methodology, document sub-basin scale forest cover pattern changes, and determine basic...
Forms are an easy-to-use interface to access a database, including a remote database on the Internet. An entity-relationship (ER} diagram, which is a pictorial representation of a database schema, is widely used in designing a database. A class diagram, which shows set of classes, relationships among them, and associations, are...
Surface crusting of soil after planting can result in poor emergence and reduced stands. The use of polysaccharides and polyelectrolytes for soil conditioning has been found to improve seedling emergence. This trial evaluated the use of a molasses and nutrient based soil conditioner (Bright Sun Soil Booster, Cargill Inc., Minneapolis,...
In this report., we address the issues of translating MATLAB scripts into SPMD-style C programs. The resulting programs, when linked with our run-time library are suitable for execution on parallel computers. We describe the design of the compiler and improvements made to it in the current version. We also describe...

There are lots of mailing systems available for Apple Macintosh computers. But when this research was started, there were no Voice Mail System for the Macintosh. However, a similar system was available for the NeXT machine. So the main goal of this research was to develop a Voice Mail System...
The Server System/1 (SS/1) Design Editor is a graphical programming tool that provides a simple interface for object oriented parallel programming. Two difficult problems with parallel programming, partitioning, end visualization are addressed by the SS/1 Design Editor. An SS/1 program is structured using object oriented design concepts. This leads to...
The objectives of this trial were to:
1. Compare onion yield under surge irrigation with continuous flow irrigation.
2. Estimate irrigation efficiency under surge irrigation and continuous flow irrigation.
3. Compare estimates of nitrogen leaching under surge irrigation with continuous flow irrigation.

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.
