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 ...
A combined artificial neural network/residual bilinearization approach for obtaining the second-order advantage from three-way non-linear data
(John Wiley & Sons Ltd, 2005-11)
Three-way instrumental data offer the second-order advantage to analysts, a property of great utility in the field of complex sample analysis in the presence of unsuspected components as potential interferents. The available ...
Achieving the analytical second-order advantage with non-bilinear second-order data
(Elsevier Science, 2021-10)
Multi-way calibration based on second-order data constitutes a revolutionary milestone for analytical applications. However, most classical chemometric models assume that these data fulfil the property of low rank bilinearity, ...
Analytical chemistry assisted by multi-way calibration: A contribution to green chemistry
(Elsevier Science, 2019-11-01)
A review is presented of recent multi-way calibration protocols involving three-, four- andfive-way data. A brief description of the various data structures and processing models isshown, with emphasis on model selection ...
Study of biosorption of rare earth metals (La, Nd, Eu, Gd) by Sargassum sp. biomass in batch systems: Physicochemical evaluation of kinetics and adsorption models
(2009-12-28)
This work evaluated kinetic and adsorption physicochemical models for the biosorption process of lanthanum, neodymium, europium, and gadolinium by Sargassum sp. in batch systems. The results showed: (a) the pseudo-second ...
A novel second-order standard addition analytical method based on data processing with multidimensional partial least-squares and residual bilinearization
(Elsevier Science, 2009-10)
In the presence of analyte-background interactions and a significant background signal, both second-order multivariate calibration and standard addition are required for successful analyte quantitation achieving the ...
Calibration and detailed analysis of second-order flow injection analysis data with rank overlap
(Elsevier Science BvAmsterdamHolanda, 2000)
Multiway calibration strategy with chromatographic data exploiting the second order advantage for quantitation of three antidiabetic and three antihypertensive drugs in serum samples
(Elsevier, 2018)
This paper proposes a multiway calibration strategy implementing the modeling with MCR-ALS and U-PLS/RBL of second-order chromatographic data for quantitation of six analytes: gliclazide, glibenclamide, glimepiride, atenolol, ...
Fourth order phase-field model for local max-ent approximants applied to crack propagation
(Elsevier Science Sa, 2016-12)
We apply a fourth order phase-field model for fracture based on local maximum entropy (LME) approximants. The higher order continuity of the meshfree LME approximants allows to directly solve the fourth order phase-field ...
Second-order multivariate models for the processing of standard-addition synchronous fluorescence–pH data. Application to the analysis of salicylic acid and its major metabolite in human urine
(Elsevier Science, 2014-01)
In the present work, we describe the determination of salicylic acid and its major metabolite, salicyluric acid, in spiked human urine samples, using synchronous fluorescence spectra measured in a flowinjection system with ...
