Fiscal output data produce versatile graphic-numeric charts

Refined computerized plotting system produces low-cost graphic-numeric charts that illustrate fiscal data on monthly incremental or cumulative basis, or both. Output is in the form of hard copy or microfilm, or visual-aid transparencies prepared from hard copy for rapid management status presentations.

Compression of weather charts by the segmented Lynch-Davisson code.

The Lynch-Davisson (L-D) code is shown to be efficient for compressing line-scanned weather charts wherein each line is divided into equal-length segments, and a separate L-D code is generated for each segment. As the number of segments increases, the L-D code length decreases appreciably, thereby simplifying the encoding and decoding operations. However, the accompanying decrease in the overall compression ratio is relatively small.

A thermodynamic chart for the Mars atmosphere

A thermodynamic chart in which area represents energy per unit of mass is constructed for the Mars atmosphere. A surface pressure of 8 millibars and an atmospheric composition of approximately 100 percent carbon dioxide are assumed. Mixing-ratio and equivalent potential temperature lines are drawn to facilitate the study of water-vapor condensation. The region of sublimation of carbon dioxide is presented for the study of the formation of carbon dioxide clouds and surface frost.
