Traditionally, the statistical quality control techniques utilize either an attributes or variables product quality measure. Recently, some methods such as three-level control chart have been developed for monitoring multi attribute processes. Control chart usually has three design parameters: the sample size (n), the sampling interval (h) and the control limit coefficient (k).The design parame...

Red fleshed apples (Malus × domestica Borkh.) differ in colour intensity between cultivars, seasons and sites. The objective of this study was to develop a procedure for predicting anthocyanin content from digital images flesh discs. Flesh cylinders uniform were excised, scanned their colours determined the R, G B L*a*b* spaces. Anthocyanin also quantified chemically. A calibration line constru...

We apply the techniques of logic programming to evaluate structure charts. We find that structure charts can be represented naturally in Prolog, and useful information can be derived in a straightforward manner. Standard techniques in the evaluation of structure charts can be formalized, and a few previous problems can be solved easily.
