Abstract:

Progress is reported concerning the use of computer controlled graphical displays in the areas of radiaton diffusion and hydrodynamics, general second order systems and autonomous third order systems of partial differential equations. Use is made of the phase plane and phase space incorporating a Rand Tablet. A subroutine has been developed to locate storage and attributes of variables in interactive FORTRAN programs. Studies are continuing on the neural mechanisms responsible for pain a study of numerical solution of partial differential equations describing non-isothermal flow has been started computer simulation is being used to study hemodynamics about lesions and artificial valves equipment has been assembled to study left ventricular dynamics. Progress is continuing on the use of computer graphics in architecture. Some progress in halftone graphics is reported with no basic developments presented. Colored halftone perspective pictures are being used to represent multivariable situations. Nonlinear waveform processing is being performed on pictures and audio recordings. Abstracts of technical reports are presented.
