Multivariable correlation analysis and its application to an industrial polymerization reactor
(2001)
The correlation analysis (CRA) theory is an important tool in the system identification field. Among its utilities, the correlation analysis enables the mathematical modeling of a process, through the estimate of its impulse ...
The Walking Environment in Lima, Peru and Pedestrian–Motor Vehicle Collisions: An Exploratory Analysis
(Taylor and Francis, 2014)
Objective: Pedestrians comprise 78% of the road fatalities in Peru. The objective of this study was to explore the relationship between the walking environment and pedestrian–motor vehicle collisions. Methods: A matched ...
Fractional order controllers for throughput and product quality control in a grinding mill circuit
(Elsevier, 2020)
This paper presents the design and application of a multiple-input–multiple-output fractional order proportional-integral (MIMO FOPI) controller to a grinding mill circuit. The MIMO FOPI controller pa- rameters are tuned ...
Joint control charts for monitoring location and dispersion
(Int Soc Sci Appl Technol, 2008-01-01)
The T-2 and the generalized variance vertical bar S vertical bar charts are used for monitoring the mean vector and the covariance matrix of multivariate processes. In this article, we propose for bivariate processes the ...
Joint control charts for monitoring location and dispersion
(2008-12-01)
The T2 and the generalized variance |S| charts are used for monitoring the mean vector and the covariance matrix of multivariate processes. In this article, we propose for bivariate processes the use of the T2 and the VMAX ...
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 ...
