Projects in 1981–1982


ARCO Gas and Oil: Evaluation of Numerical Dispersion and Grid Orientation Effects for the Two-Phase Immiscible Displacement Problem

Advisor
James Frauenthal

The purpose of this project was to investigate methods for improvement in numerical dispersion and grid orientation in the finite difference formulation for the two-dimensional, two-phase immiscible displacement problem and to develop new techniques to overcome these effects. The ARCO CRAY-1 was available for use by the project team via a time-sharing arrangement through the VAX.

General Dynamics: Forecasting and Planning for Research and Development

Advisor
Robert Borrelli

The Technical Programs Group at General Dynamics, Pomona Division, has built an internal organization to forecast breakthrough technologies, and developed eight-year strategy plans to exploit them. This project developed models to facilitate these forecasting and planning efforts. Useful tools were drawn from the areas of managerial economics, statistics, operations research and finance. The spring semester 1981 was devoted to problem formulation, preliminary model construction and data collection. Model refinement, solution, validation and interpretation was implemented in a flexible planning system during 1981-82.

General Dynamics: Modeling, Forecasting and Planning for Research and Development

Advisor
Eliot Bradford

Long range planning in areas involving emerging technologies is becoming increasingly important to the aerospace and defense industries. The Technical Programs Group at General Dynamics, Pomona Division, has built an internal organization to forecast breakthrough technologies, and developed eight-year strategic plans to exploit them. The problem for the Math Clinic project was to develop models to facilitate these forecasting and planning efforts. It was expected that useful tools would be drawn from the areas of managerial economics, statistics, operations research and finance. These models would have to be in terms for which data was available, in order to have explicit applications. Because of the inherently volatile nature of the business, an adaptive feature was important. Because of the varied uses and users which were anticipated, simplicity was also of some importance. Spring semester 1981 was devoted to problem formulation, model construction and data collection. It was planned that refinement, solution, validation and interpretation of the models would be implemented in a flexible software system during 1981-82.

Interstate Electronics: Automatic Word Recognition

Advisor
Ellis Cumberbatch
College
CGU

The purpose of this project was to study Interstate Electronics' speech recognition device and to make recommendations for possible modifications.

Lockheed: Computational Aerodynamics

Advisor
Melvin Henriksen
College
CGU

The purpose of this project was to aid Lockheed in certain aspects of airplane design. Significant attention was paid to solving a class of linear systems.

Texas Instruments, Inc.: Synthetic Speech Listener

Advisor
John Molinder

Investigation of various LPC modeling algorithms using metrics other than least squares (e.g., Chebyshev, etc.) which will improve performance as perceived by the synthetic speech listener. This may require work with an array processor–possibly via remote hook-up. The team was given a 3-day orientation course on LPC speech modeling at the TI Dallas site.

U.S. Forest Service: Forest Fire Suppression

Advisor
James Lucke
College
CMC/CGU

The purpose of this project was to study procedures for attacking large fires. Of particular interest was how personnel and equipment should be deployed in the first stages of suppression.

U.S. Forest Service: Network Analysis of Fire Management

Advisor
Stan Hales
College
POM/CGU

As a large organization, the Forest Service needed to coordinate activities in its research branch. This project investigated ways of doing this using network analysis (related to graph theory and combinatorics).
