Although it is well known that the performance of attribute control charts decreases significantly when assumption process parameters invalid, this prevalent in pertinent literature. However, most practical applications, have to be estimated from a finite in-control Phase I sample, and therefore should evaluated perspective parameters. In paper, we compare run length properties hypergeometric n...

This paper describes a fast approach to automatic point label de-confliction on interactive maps. The general Map Labeling problem is NP-hard and has been the subject of much study for decades. Computerized maps have introduced interactive zooming and panning which has intensified the problem. Providing dynamic labels for such maps typically requires a timeconsuming pre-processing phase. In the...
