Exploiting the synergistic effect of concurrent data signals: Low-level fusion of liquid chromatographic with dual detection data
(Elsevier Science, 2018-08)
A low-level data fusion strategy was developed and implemented for data processing of second-order liquid chromatographic data with dual detection, i.e. absorbance and fluorescence monitoring. The synergistic effect of ...
Rapid determination of retinoic acid and its main isomers in plasma by second order high-performance liquid chromatography data modeling
(Springer Heidelberg, 2014-11)
This paper reports the development of a method based on high-performance liquid chromatography (HPLC) coupled to second-order data modeling with multivariate curve resolution-alternating least-squares (MCR–ALS) for ...
Second order multivariate curve resolution of Fourier Transform Infrared Spectroscopic data of the photo-induced crosslinking of thymine functionalized polymers
(Elsevier Science, 2014-04)
A meaningful characterization of the photo-induced curing process of materials based on styrene monomers functionalized with thymine and charged ionic groups was accomplished using FT-IR spectroscopy in combination with ...
Second and Third Order Ionospheric Effects on GNSS Positioning: A Case Study in Brazil
(Springer-verlag Berlin, 2012-01-01)
The Global Positioning System (GPS) transmits signals in two frequencies. It allows the correction of the first order ionospheric effect by using the ionosphere free combination. However, the second and third order ionospheric ...

On second-order calibration based on multivariate curve resolution in the presence of highly overlapped profiles
(Elsevier Science, 2020-02)
Multivariate curve resolution has been applied to both simulated and experimental data sets where high or even complete overlapping occurs between component profiles in one data mode. It is shown that rotational ambiguity ...
MINRES for Second-Order PDEs with Singular Data
(2022)
Minimum residual methods such as the least-squares finite element method (FEM) or the discontinuous Petrov-Galerkin (DPG) method with optimal test functions usually exclude singular data, e.g., non-square-integrable loads. ...
Unfolded partial least-squares with residual quadrilinearization: A new multivariate algorithm for processing five-way data achieving the second-order advantage. Application to fourth-order excitation-emission-kinetic-pH fluorescence analytical data
(Elsevier Science, 2011-12)
Unfolded partial least-squares in combination with residual quadrilinearization (U-PLS/RQL), is developed as aew latent structured algorithm for the processing of fourth-order instrumental data. In order to check its ...
