Drawing of Barrel Plating Solution

Journal of the Metal Finishing Society of Japan, 1962
It is essential to decrease the time of analysis for simplifying the control of plating bath. Because, according to the result of analysis, a suitable chemical should be added in proportion to the variation of solution composition, which is caused by three main factors, chemical, electrochemical and mechanical factors.

Problems and solutions for drawing fronts objectively [PDF]

Meteorological Applications, 2001
AbstractA recent requirement charged to the Aviation Weather Center (AWC) is to produce significant weather charts for aviation users with, among other forecast products, forecast locations of significant fronts. To increase forecaster productivity, the AWC decided to evaluate the possibility that fronts should be first drawn objectively. Hewson (1998)
