The reversed-axis method to estimate precision in standard additions analysis
(2016-01-01)
The standard additions (SA) method is one of the most important calibration strategies in quantitative chemical analysis. It is a powerful tool to minimize matrix effects and enable precise and accurate determinations. On ...
Técnicas geoestatísticas aplicadas ao mapeamento de variáveis limnológicas e quantificação da incerteza associada às estimativas
(2015-01-01)
Aim: This study aimed to map the concentrations of limnological variables in a reservoir employing semivariogram geostatistical techniques and Kriging estimates for unsampled locations, as well as the uncertainty calculation ...
Adaptive control charts for attributes
(2003-06-01)
We develop a general model for adaptive c, np, u and p control charts in which one, two or three design parameters (sample size, sampling interval and control limit width) switch between two values, according to the most ...
Accuracy of nutritional diagnostics for phosphorus considering five standards by the method of diagnosing nutritional composition in sugarcane
(Taylor & Francis Inc, 2020-02-22)
The accuracy of nutritional diagnoses can enable the definition of the best set of standards by the method of nutritional composition diagnosis (CND) in sugarcane. In this sense, the purpose of this study was to perform ...
It is okay to be average when quantifying rangeland dynamics Comment on: Easdale, M.H & Bruzzone, O. 2015: Anchored in 'average thinking' in studies of arid rangeland dynamics e The need for a step forward from traditional measures of variability. J. Arid. Environ. 116: 77-81
(Elsevier, 2016-01)
Easdale and Bruzzone (2015) recently indicated that to better capture temporal patterns of rangeland dynamics, there is a need to move forward from simple measures of variability such as mean, standard deviation, and ...
