Tamanho de amostra para avaliar a multicolinearidade em caracteres de cultivares de centeio
(Universidade Federal de Santa MariaBrasilAgronomiaUFSMPrograma de Pós-Graduação em AgronomiaCentro de Ciências Rurais, 2019-02-21)
The aim of this work was to determine the sample size (number of plants) necessary to estimate the indicators of the degree of multicollinearity - condition number (NC), determinant of correlation matrix (DET) and variance ...
A synthetic control chart for monitoring the pprocess mean and variance
(2006-12-01)
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 Xl is close ...

Capacidade de coleta de três métodos de amostragem e tamanho de amostra para lagartas e percevejos em soja
(Universidade Federal de Santa MariaBRAgronomiaUFSMPrograma de Pós-Graduação em Agronomia, 2012-02-16)
This study aimed to compare the caterpillar and stinkbug collection capability of
sampling methods and to determine the sample size (number of sampling points) to estimate
the number of caterpillars and stinkbugs collected ...
Morphological modifications and surface amorphization in ZnO sonochemically treated nanoparticles
(2013-05-01)
Application of nanoscale materials in photovoltaic and photocatalysis devices and photosensors are dramatically affected by surface morphology of nanoparticles, which plays a fundamental role in the understanding of the ...
A new chart for monitoring the covariance matrix of bivariate processes
(Taylor & Francis Inc, 2008-01-01)
In this article we consider a control chart based on the sample variances of two quality characteristics. The points plotted on the chart correspond to the maximum value of these two statistics. The main reason to consider ...

Power of Stable isotope techniques to detect size-based feeding in marine fishes
(Inter-Research, 2010-05)
Stable isotope techniques are now the most frequently applied method to investigate size-based variation in fish trophic position (TP), and data suggest changes in TP with body size are common. However, of 131 collated ...
Variabilidade temporal e espacial do tamanho de amostra da temperatura mínima do ar no Rio Grande do Sul, Brasil
(Universidade Federal de Santa Maria (UFSM), 2006-08-01)
Com o objetivo de verificar a existência de variabilidade temporal e espacial do tamanho de amostra da temperatura mínima do ar média mensal de trinta e sete municípios do Rio Grande do Sul, utilizaram-se os dados de ...
