Projects in 1976–1977

Atomics International: Fuel Element Life Performance Model

Jerome Spanier

Continuation of '75-76 project. Effort in 1976-77 was concentrated on the development and solution of a system of differential equations describing the space--time dependence of the reactor fuel assembly. A novel fluid model was created and used to provide information of use in following the restructuring of the fuel.

Chevron Oil Field Research Company: A Mathematical Model of Compacting Sediment with Diagenesis

Sedat Serdengecti
Courtney Coleman

For the past two semesters, mathematics clinic teams have constructed and digitally simulated a mathematical model of a consolidation process for predicting abnormally high fluid pressures in sedimentary basins. This clinic team validated the model and extended it by taking into account other physical aspects, such as diagenesis, present in the consolidation process.

Honeywell Marine Systems Division: Development of Trainer Display Programs

Stavros Busenberg

This clinic project designed, coded and documented all the computer graphics programs that are needed to display and change positions and courses of sea vessels on two cathode ray tube screens driven by a minicomputer. This program is part of a system that is now being used to train sonar operators.

Jet Propulsion Laboratory: Design of a General Purpose Photo Composition System

Yechiam Yemini

This project designed and implemented a program for the computerized photocomposition of documents. Portability of the program was a major objective. The program design and implementation permitted the program to be installed with relatively modest additional effort on any medium to large computer system supporting ANS FORTRAN. The program does not drive typewriters, printers, or special-purpose photocomposition devices.

Pomona Valley Municipal Water District: Predicting Groundwater Nitrate Concentrations

Stavros Busenberg

This project developed a mathematical model for the concentration of certain pollutants in underground water. A computer program based on this model was also produced by the project. This program can be used to determine nitrate concentrations in the groundwater and to produce graphical displays of such levels.
