Evaluation of complex spectral-pH three-way arrays by modified bilinear least-squares: Determination of four different dyes in interfering systems
(Royal Society of Chemistry, 2005-09)
This article reports on the first application of a modified version of the bilinear least-squares model to absorbance-pH second-order data recorded for complex samples. The latter are composed of fruit drink powders, where ...
A Represention Theorem for Second-Order Functionals
(Cambridge University Press, 2015-09)
Representation theorems relate seemingly complex objects to concrete, more tractable ones. In this paper, we take advantage of the abstraction power of category theory and provide a datatype-generic representation theorem. ...
Second-order cone approximation for voltage stability analysis in direct-current networks
(Cartagena de Indias, 2020-09-24)
In this study, the voltage stability margin for direct current (DC) networks in the presence of constant power loads is analyzed using a proposed convex mathematical reformulation. This convex model is developed by employing ...
A mixed-integer second-order cone model for optimal siting and sizing of dynamic reactive power compensators in distribution grids
(Cartagena de Indias, 2022-06-20)
The problem of the optimal placement and sizing of dynamic reactive power compensators in AC distribution networks is addressed in this paper from convex optimization. The exact mixed-integer nonlinear programming (MINLP) ...
Bilinear least squares (BLLS) and molecular fluorescence in the quantification of the propranolol enantiomers
(Elsevier Science BvAmsterdamHolanda, 2008)
Determination of pesticides and metabolites in wine samples by HPLC-DAD and second-order calibration methods
(Elsevier Science, 2007-12)
The second-order calibration models PARAFAC and the recently introduced BLLS were applied to several chromatographic-diode array detection systems, where overlap of interferences with the compounds of interest was observed, ...
