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...
Polyacrylamide and straw mulch were used to reduce soil erosion on furrow irrigated potatoes. The PAM rate started out at 1 lb/ac per irrigation, then in the second irrigation of the wheel rows the rate was reduced to 0.2 lb/ac. The rate was increased to 0.5 lb/ac for all subsequent...

Use of unregistered materials or use of any registered pesticides inconsistent with its label is against both Federal Law and State Law.
A Kalman filter was developed to recover information on short period variations of ocean circulation from the satellite altimeter signals for the North Pacific Ocean. The ocean circulation at each grid point is specified by three variables: sea level height h, zonal velocity u, and meridional velocity v. In our...
We believe concreteness, direct manipulation and responsiveness in a visual programming language increase its usefulness. However, these characteristics present a challenge in generalizing programs for reuse, especially when concrete examples are used as one way of achieving concreteness. In this paper, we present a technique to solve this problem by...
One of the main problems in debugging parallel programs is in determining how far a parallel program has executed when it crashes or stops. Even if the program dumps core files for all the parallel processes, the information is at such a low level that it is difficult to interpret...
Dataparallel C has been designed for various kinds of architectures and was developed jointly at University of New Hampshire and Oregon State University.
This project dealt with porting the libraries to the nCUBE 2 system and helping a user compile his programs on nCUBE 2 directly from a Sun workstation...
In this paper we describe a fuzzy logic based control system implemented on a PC architecture. The rule based inference engine of this expert system is easily configured through an ascii text file and is demonstrated to be capable of controlling various simulations, including an inverted pendulum. The controller is...
