The Tertiary geologic evolution of the Oregon and Washington continental margin was molded by episodic periods of convergence between the Pacific oceanic plates and the North American plate. This margin is the site of a deep basin that is floored by Paleocene to lower Eocene oceanic crust and contains more...
Straw mulch was evaluated on a furrow-irrigated sugar beet field to determine potential benefits In Increased yield, better soil moisture status, and reduced soil erosion.
A Nyssa slit loam soil was bedded for potatoes. Furrow irrigation for 11 hours at four gallons per minute on a 2.5 percent slope resulted in 17.7 tons of soil lost per acre. Soil loss was reduced to 2.8 tons per acre by the use of 790 lbs/acre of wheat...
Although Mexico is one of the major lime producing countries in the world the crop is not completely utilized. In this paper some ideas are reviewed in relation to various possible products that can be obtained from the efficient processing of limes. Among these are the extraction of the juice,...

This survey looks at five different polygon breaking algorithms and compares them. The criteria for comparison are:
1. Complexity of the algorithm.
2. The number and type of subpolygons produced.
3. The classes of input polygons that can be broken.
The best algorithm is then coded and a comparison is...
This paper presents the initial results from an empirical study of mechanical design engineers. In this study, six engineers were video-taped solving real mechanical design problems. Preliminary analysis of this protocol data has yielded several important findings, including (a) mechanical designers progress from systematic to opportunistic behavior as the design...
Acoustic position estimation is used where high accuracy navigation is required over a small area, such as for searching or for collecting gravitational or geomagnetic data. In this position estimation method, a surface ship or submersible periodically sends out a high-frequency acoustic 'ping' at a prearranged frequency. This ping is...
System architectures for interconnecting large numbers of processors are being widely studied [AG82,TH75,TR82]. Of particular interest in such architectures is the exploitation of concurrency among processors. This concurrency can be parallelism, in which different parts of a single data case are processed at the same time, or pipelining, in which...
This grant supported acquisition of a minicomputer system for departmental research. The equipment selected is a DEC VAX-11/750 system, installed in remodeled space in the Computer Science (formerly Farm Crops) Building. Grant funds for equipment acquisition were supplemented by support from the Tektronix Foundation.
After completion of the physical facilities...
Three different approaches to type checking have been taken in object-oriented programming languages. Smalltalk-80 uses run-time type checking. C++ uses subtypes. A third alternative is to use parameterized types. We examine the difficulties of programming in an object-oriented fashion with compile-time type checking and argue that parameterized types are better...
