Abstract: This report presents a simple, quantitative analytical method for determining the percent of a particular group or structure within a urethane compound by means of the infrared spectrophotometer.

Abstract: A mathematical model for an associative memory is proposed which uses associative addressing and distributed storage.

Foreword: There has been relatively little work reported on deriving quantitative estimates of the degradation to a man-machine system resulting from human errors. One approach, used in the Reliability Department of Sandia Corporation, is presented here as an example of how such estimating can be done.

Abstract: The APAR-3G system is an automatic programming, controlling and recording machine which is readily adaptable to a wide variety of automated data acquisition and constrol system applications. It is physically and logically modular to permit the assemby of minimum or maximum capability machines. This system can perform the necessary acquisition and control in a typical factory environment and can generate an output (for data reduction) which is compatible with available computer systems.

Abstract: This is the second progress report on the work performed at Sandia Corporation in the use of spectrographic techniques in plasmajet diagnostics. Typical results of spectrographic data from argon and nitrogen plasmajets are included. For the argon jet, the results from line intensity measurements of ionized and unionized atoms generally give good information. However, results from hydrogen line broadening measurements indicate several unexplained discrepancies. For the nitrogen jet, the N2 (0, 0) and N2 (0, 1) bands from the first negative series were used to determine a rotational temperature.
