TEXAS BIANNUAL OF ELECTRONICS RESEARCH NO. 4. A SUMMARY OF RESEARCH FOR THE PERIOD APRIL 1, 1966 THROUGH SEPTEMBER 30, 1966.

Abstract

Research topics in progress, recent findings, and future plans in the areas of biomedical electronics; information sciences; physical, quantum, and plasma electronics; and space, atmospheric and earth radio sciences are presented. This fourth biannual is highlighted by definitive new results recently obtained in several of these areas. A mathematical model of a biological clock is developed to predict the locomotor reaction of Passer domesticus to an environmental light cycle. The revoveries of two evoked responses, namely an electroretinogram and an electroencephalogram, in a visual system following intense light flashes are reported. An algorithm which, given a sequential machine with completely specified state and output variables, yields all code assignments for which the state-variable and output-variable functions are two-assumable is formulated. A single reference orbit is given for integrating through the boundaries of activity spheres, a calculation required for the trajectory of a lunar or interplanetary space mission. An optimal adaptive estimator of stochastic processes with random parameters is presented. A Lemma which is a partial extension of the strong law of large numbers is proven and applied to a pattern recognition problem. Classical microwave gas breakdown theory is extended to optical frequencies and shown to confirm experimental laser-induced breakdown in super-high pressure gases. Mach-Zehnder interferometry of laser induced discharges delineates the onset of heating and ionization in gases. Experimental observations of strong blast waves produced in laser induced plasmas in high pressure gases are shown to agree closely with predictions based on strong blast wave theory.
