Computer program which yields CRT displays will decrease the time and labor required to reduce and provide a profile plot of surface plate calibration data. The displays depict actual and resolved data points for each individually calibrated line.
Analytical drafting curves provide explicit mathematical expressions for any numerical data that appears in the form of graphical plots. The curves each have a reference coordinate axis system indicated on the curve as well as the mathematical equation from which the curve was generated.
Computer program for plotting antenna radiation amplitude and phase patterns
Subroutines written in Fortran IV for generating printed plots as part of normal output
Computer program calculates surface area and pore size distribution of powders, metals, ceramics, and catalysts, and prints and plots the desired data directly. Surface area calculations are based on the gas adsorption technique of Brunauer, Emmett, and Teller, and pore size distribution calculations are based on the gas adsorption technique of Pierce.
Fortran 4 computer program for calculating and plotting surface area and pore size distribution data obtained by gas adsorption
FORTRAN 4 computer program for multichannel pulse height analyzer spectra, calculated photon number, and energy spectra plotting
Modified vibration transducer calibration system for directly producing sensitivity versus frequency range plots
Anomalies in solar spectral irradiance in tropopause using Langley plot applied to silicon solar cell output
By substitution of resistance paper for normal plotting paper, an x-y plotter can be used to draw automatically the equipotential lines between components represented in planar form on the paper. This technique is used for high voltage electronic components of complex configuration for the prediction of stress in the intervening insulation.
FORTRAN 4 subroutines to generate printed plots as normal output
Numerical analysis of spiraling in ion molecule collisions with polar targets using computer plotting techniques
High speed printer for hard copy alphanumeric listings and digital data plots
Data plots obtained from ion chamber and electron spectrometer experiments aboard OGO A and OGO C satellites
Automatic heteroatomic plotting of high resolution mass spectral data, presenting relative intensity vs elemental composition in bar form
Alphanumeric listing and digital data x-y plotting by high speed printer, describing equipment modifications and control software
Computer made movies and time history plots for ion-dipole collisions involving polar molecules /CO, HCL and acetonitrile/
Vacuum tube bridge operates in two modes, tracing and fixed potential. It reduces plotting time by fifty percent and improves measurement precision.
