Developing and Implementing an R Shiny Application to Introduce Multivariate Calibration to Advanced Undergraduate Students
(American Chemical Society, 2020-04)
During a short chemometrics course in the seventh semester of the chemistry undergraduate program, students receive a brief theoretical introduction to multivariate calibration, focused on partial least-squares regression ...
Microparticle manipulation and imaging through a self-calibrated liquid crystal on silicon display
(MDPI, 2018-11)
We present in this paper a revision of three different methods we conceived in the framework of liquid crystal on silicon (LCoS) display optimization and application.We preliminarily demonstrate an LCoS self-calibration ...
LCoS display phase self-calibration method based on diffractive lens schemes
(Elsevier, 2018-07)
An experimental method to calibrate Liquid Crystal on Silicon (LCoS) displays by self-generating lens configurations on the studied device is proposed in this paper. On the one hand, a split-lens is displayed in the LCoS ...
Second-order and higher-order multivariate calibration methods applied to non-multilinear data using different algorithms
(Elsevier, 2011-04)
We discuss and evaluate the current state of second-order and higher-order multivariate calibration methods devoted to the determination of compounds in non-multilinear data systems. We examine possible causes of multilinearity ...
A 2GS/s 6-bit CMOS time-interleaved ADC for analysis of mixed-signal calibration techniques
(Springer, 2015-07)
A 2-GS/s 6-bit time interleaved (TI) successive approximation register (SAR) analog-to-digital converter (ADC) is designed and fabricated in a 0.13 lm CMOS process. The architecture uses 8 time-interleaved track-andhold ...
Contribution to second-order calibration based on multivariate curve resolution with and without previous chromatographic synchronization
(Elsevier Science, 2019-10-31)
Rotational ambiguity in the bilinear solutions provided by multivariate curve resolution - alternating least-squares (MCR-ALS) leads to an additional source of uncertainty in the estimation of analyte concentrations by ...
Construction and calibration of a goniometer to measure contact angles and calculate the surface free energy in solids with uncertainty analysis
(Elsevier, 2018-12)
Here, we present the construction and calibration of a low-cost goniometer to measure contact angles by the sessile drop method. Besides, we propose a simple and fast method to calculate the uncertainty in the determination ...
Simultaneous determination of ascorbic and uric acids and dopamine in human serum samples using three-way calibration with data from square wave voltammetry
(Elsevier Science, 2016-11)
We present for the first time a novel analytical method based on a model of three-way calibration using second-order data generated from the combination of records of forward (oxidation) and reverse (reduction) currents ...
Antarctic network of lamp-calibrated multichannel radiometers for continuous ozone and uv radiation data
(Copernicus Publications, 2008-02)
Three NILU-UV multichannel radiometers have been installed in 1999 at the Argentinian sites of Ushuaia (54S), Marambio (64S) and Belgrano-II (77S) in order to continuously monitor UV radiation, photosynthetically active ...
New developments for the sensitivity estimation in four-way calibration with the quadrilinear parallel factor model
(American Chemical Society, 2012-02)
Appropriate closed-form expressions are known for estimating analyte sensitivities when calibrating with one-, two-, and three-way data (vectors, matrices, and three-dimensional arrays, respectively, built with data for a ...
