Any chart with at most one crossing is a ribbon chart

Max Chart: Combining X-bar Chart and S Chart

Control chart techniques have been widely used in industries to monitor a process in quality improvement. Whenever we deal with variables data, we usually employ a combination of X-bar chart and R chart (or S chart) to monitor both the center and the spread of the process. In this paper, we propose a simple alternative, that is, we design a single chart to monitor both the center and the spread...

3 A Compilation - Chart

Recent work in categorial grammar has seen proposals for a wide range of systems , diiering in their`resource sensit-ivity' and hence, implicitly, their underlying notion ofìinguistic structure'. A common framework for parsing such systems is emerging, whereby some method of linear logic theorem proving is used in combination with a system of labelling that ensures that only deductions appropri...

Any Knot Complement Covers at Most One Knot Complement

Given a 3-manifold M , there are generically infinitely many manifold which covers M . However, if we are restricted to the category of knot complements, the situation is quite different. It can be shown (see Lemma 1 and bellow) that if the complement E(K) of a knot K is n-fold covered by some knot complement, then the covering is cyclic, and K admits a cyclic surgery, i.e. a Dehn surgery such ...

Control chart based on residues: Is a good methodology to detect outliers?

The purpose of this article is to evaluate the application of forecasting models along with the use of residual control charts to assess production processes whose samples have autocorrelation characteristics. The main objective is to determine the efficiency of control charts for individual observations (CCIO) and exponentially weighted moving average (EWMA) charts when they are applied to res...
