Initialization effects in two-component second-order multivariate calibration with the extended bilinear model
(Elsevier Science, 2020-08-15)
Bilinear decomposition of an augmented data matrix is usually complicated by the phenomenon of rotational ambiguity. If the latter is significant, quantitative and qualitative information of the recovered profiles may be ...
The effect of data matrix augmentation and constraints in extended multivariate curve resolution–alternating least squares
(John Wiley & Sons Ltd, 2017-03)
The reliability of results obtained by multivariate curve resolution (MCR) methods is strongly dependent on the absence or presence of a small degree of rotational ambiguity associated to them. In this work, the effect of ...
Second-order multivariate calibration with the extended bilinear model: Effect of initialization, constraints, and composition of the calibration set on the extent of rotational ambiguity
(John Wiley & Sons Ltd, 2020-03-15)
Extended bilinear modeling is popular in second-order multivariate calibration, particularly when the matrix data for each sample are of chromatographic origin. Since elution time profiles vary across samples, in both shape ...
Block rotations within the northern Peruvian Altiplano
(IRD ÉditionsFRA, 2008)
Counterclockwise tectonic rotations in the northern central Andes and clockwise rotations in the southern Central Andes have been systematically reported (see Roperch et al. 2006 and Arriagada et al., 2006 for a recent ...

A catalog of rotational and radial velocities for evolved starsA catalog of rotational and radial velocities for evolved stars
(EDP Sciences, 2006-07-20)
Aims.The present paper describes the first results of an observational program intended to refine and extend the existing measurements of metal-poor stars, with an emphasis on field evolved stars. Methods.The survey was ...
