On the sample mean of locally stationary long-memory processes
(ELSEVIER SCIENCE BV, 2010)
Some asymptotic statistical properties of the sample mean of a class locally stationary long-memory process are studied in this paper. Conditions for consistency are investigated and precise convergence rates of the variance ...
A new sampling strategy for the Shewhart control chart monitoring a process with wandering mean
(Taylor &francis Ltd, 2015-07-18)
In many processes, such as in chemical and process industries, the observations of a quality characteristic to be monitored may be correlated, if sampling intervals are short. Correlation can be modelled by considering the ...

Synthetic control chart for monitoring the pprocess mean and variance
(Int Soc Sci Appl Technol, 2006-01-01)
In this article, we consider the synthetic control chart with two-stage sampling (SyTS chart) to control the process mean and variance. During the first stage, one item of the sample is inspected; if its value X, is close ...
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 ...

Standardization of platelet parameters determination in blood samples collected with EDTA
(2003-12-01)
The Abbott Cell-Dyn 3000 automated hematological analyzer prepares a histogram of platelet volume, which is measured by a technique using electrical impedance, inferring from its platelet count (PLT), mean platelet volume ...
Preliminary results concerning the VSS X- chart with unknow in-control parameters
(2010-12-01)
The VSS X- chart is known to perform better than the traditional X- control chart in detecting small to moderate mean shifts in the process. Many researchers have used this chart in order to detect a process mean shift ...
