IntCal, SHCal, or a mixed curve? choosing a 14C Calibration curve for archaeological and paleoenvironmental records from Tropical South America
(University of Arizona. Department of Geosciences, 2018-06)
Because the 14C calibration curves IntCal and SHCal are based on data from temperate latitudes, it remains unclear which curve is more suitable for archaeological and paleoenvironmental records from tropical South America. ...
Standard addition calibration: Is it enough for an analytical result estimation?. Spectrophotometric experiments for analyte quantitation in real samples
(Research Trends, 2021-12)
Analytical method validation is the first step for quantitative analysis, and both validation and quantitation are usual and fundamental tasks in analytical work; hence it is extremely important to perform them in the most ...
Sensitivity for Multivariate Calibration based on Multilayer Perceptron Artificial Neural Networks
(American Chemical Society, 2020-08)
The use of machine learning for multivariate spectroscopic data analysis in applications related to process monitoring has become very popular since non-linearities in the relationship between signal and predicted variables ...
Calibration aspects of the JEM-EUSO mission
(Springer, 2015-11)
he JEM-EUSO telescope will be, after calibration, a very accurate instrument which yields the number of received photons from the number of measured photo-electrons. The project is in phase A (demonstration of the concept) ...
Proton double irradiation field-cycling nuclear magnetic resonance imaging: Testing new concepts and calibration methods
(Institute of Electrical and Electronics Engineers, 2020-11-11)
Double resonance experiments in field-cycling nuclear magnetic resonance (NMR) are powerful tools for the indirect detection of quadrupolar and electron resonances, dynamic nuclear polarization-induced signal amplification, ...
Obtaining accurate and calibrated coil models for transcranial magnetic stimulation using magnetic field measurements
(Springer Heidelberg, 2020-07)
Currently, simulations of the induced currents in the brain produced by transcranial magnetic stimulation (TMS) are used to elucidate the regions reached by stimuli. However, models commonly found in the literature are too ...
Multichannel radiometer calibration: A new approach
(Optical Society of America, 2005-09)
The error in irradiance measured with Sun-calibrated multichannel radiometers may be large when the solar zenith angle (SZA) increases. This could be particularly detrimental in radiometers installed at mid and high ...
A review of multivariate calibration methods applied to biomedical analysis
(Elsevier Science, 2006-01)
The determination of the contents of therapeutic drugs, metabolites and other important biomedical analytes in biological samples is usually performed by using high-performance liquid chromatography (HPLC). Modern multivariate ...
MVC3: A MATLAB graphical interface toolbox for third-order multivariate calibration
(Elsevier Science, 2012-07-02)
A new MATLAB graphical interface toolbox for implementing third-order multivariate calibration methodologies is discussed. Multivariate Calibration 3 (MVC3) is a sequel of the already described first-order (MVC1) and ...
Determination of ochratoxin A in coffee and tea samples by coupling second-order multivariate calibration and fluorescence spectroscopy
(Elsevier Science, 2020-11-01)
A new method to quantify the mycotoxin ochratoxin A (OTA) in coffee and tea samples is proposed based on second-order multivariate calibration and excitation-emission fluorescence matrix (EEFM) data. Experimental conditions ...
