The Use of Computer Networks in Data Gathering and Data Analysis.
Yost, Michael; Bremner, Fred
This document describes the review, analysis, and decision-making process that Trinity University, Texas, went through to develop the three-part computer network that they use to gather and analyze EEG (electroencephalography) and EKG (electrocardiogram) data. The data are gathered in the laboratory on a PDP-1124, an analog minicomputer. Once gathered, they are converted from analog-to-digital (A/D) and sent by the PDP to an IBM 370 3031. The data are then submitted to a fast fourier analysis (FFT) on the IBM computer. Once the FFT are completed, the data are accessed by an IBM PC-XT which is equipped with an IRMA network system. The PC is used in its emulation mode to access the data in the mainframe where either SPSS (Statistical Package for the Social Sciences) or SAS (Statistical Analysis System) is then used to do the initial statistical analyses. When necessary, subsets of the data are transferred to the PC where other computer programs are used to analyze the data. In many instances, they are returned to the mainframe from the PC where they are submitted to multivariate statistical analysis. Finally, all of the data are stored on floppy disks which are prepared on the PC. (Author/THC)
