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 ...
Modeling second-order data for classification issues: Data characteristics, algorithms, processing procedures and applications
(Elsevier, 2018-10)
This review outlines some of the challenging aspects of applying second-order data modeling in classification issues analyzing selected examples of current applications. The main analytical platforms used for classification ...
Chemometric modeling of kinetic-fluorescent third-order data for thiamine determination in multivitamin complexes
(Elsevier Science, 2016-03)
Thiamine (vitamin B1) was converted into a fluorescent thiochrome by oxidation catalyzed by Hg2+ in alkaline medium. The kinetic evolution for this conversion was followed by emission-excitation spectroscopy generating a ...
Combining standard addition method and second-order advantage for direct determination of salicylate in undiluted human plasma by spectrofluorimetry
(Elsevier Science BvAmsterdamHolanda, 2006)
Optimal control of infinite dimensional bilinear systems: application to the heat and wave equations
(Springer Verlag, 2018)
In this paper we consider second order optimality conditions for a bilinear optimal control problem governed by a strongly continuous semigroup operator, the control entering linearly in the cost function. We derive first ...
Optimal wave energy extraction for oscillating water columns using second-order sliding mode control
(Institution of Engineering and Technology, 2020-07-06)
Ocean waves are an important renewable energy resource and several fields of R&D are concurrently working to improve technologies for harnessing their power. In that context, this study presents a control to optimise the ...
Recent Applications of First- and Second-Order Multivariate Calibration to Analytical Chemistry
(Aoac Int, 2014-01)
This report reviews recent literature on the application of multivariate calibration techniques to both first- and second-order data, aimed at the analytical determination of analytes of interest or sample properties in a ...
Application of the correlation constrained multivariate curve resolution alternating least-squares method for analyte quantitation in the presence of unexpected interferences using first-order instrumental data
(Royal Society of Chemistry, 2010-01)
Correlation constrained multivariate curve resolution-alternating least-squares is shown to be a feasible method for processing first-order instrumental data and achieve analyte quantitation in the presence of unexpected ...
