An adaptive chart for monitoring the process mean and variance
(Wiley-Blackwell, 2007-11-01)
Traditionally, an (X) over bar chart is used to control the process mean and an R chart is used to control the process variance. However, these charts are not sensitive to small changes in the process parameters. The ...
Mathematical education of young and adults: pedagogical implications of historical-cultural theory
(Univ Federal Tocantins, Campus Tocantinopolis, 2018-05-01)
The present study addresses some pedagogical implications of historical-cultural theory for the exploration of mathematical ideas in the field of youth and adult education (EJA). Starting from an analysis of the state of ...

Monitoring the mean vector and the covariance matrix of multivariate processes with sample means and sample ranges
(Associação Brasileira de Engenharia de Produção, 2011-06-01)
Os gráficos conjuntos de e R e S² são os mais utilizados para o monitoramento da média e da dispersão do processo. Com os tamanhos de amostra usuais de 4 e 5, os gráficos de R em uso conjunto são ligeiramente inferior aos ...

Efficiency issues of evolutionary k-means
(ELSEVIER SCIENCE BV, 2011)
One of the top ten most influential data mining algorithms, k-means, is known for being simple and scalable. However, it is sensitive to initialization of prototypes and requires that the number of clusters be specified ...
Modifications and Alternatives to the Tests of Levene and Brown & Forsythe for Equality of Variances and Means
(UNIV NAC COLOMBIA, DEPT ESTADISTICA, 2008)
The usual tests to compare variances and means (e. g. Bartlett`s test and F-test) assume that the sample comes from a normal distribution. In addition, the test for equality of means requires the assumption of homogeneity ...
Evolutionary k-means for distributed data sets
(ElsevierAmsterdam, 2014-03-15)
One of the challenges for clustering resides in dealing with data distributed in separated repositories, because most clustering techniques require the data to be centralized. One of them, k-means, has been elected as one ...
