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 ...
Evaluation of the ambiguity in second-order analytical calibration based on multivariate curve resolution: A tutorial
(Elsevier Science, 2022-08)
The aims of the present tutorial are the following: (1) to show the importance of applying all the chemically sensible constraints which are necessary to retrieve interpretable component profiles when processing second-order ...
On the propagation of methodological uncertainties in Depth Sensing Indentation data analysis: A brief and critical review
(Pergamon-Elsevier Science Ltd, 2020-04)
A systematic and critical review about the propagation of uncertainties related to the Depth Sensing Indentation data analysis standard procedures and its effect on the estimation of Young´s modulus of materials is reported. ...
A down-to-earth analyst view of rotational ambiguity in second-order calibration with multivariate curve resolution: a tutorial
(Elsevier Science, 2021-04)
Rotational ambiguity is a phenomenon with the potential of generating an uncertainty in the estimation of analyte concentrations in protocols based on matrix instrumental data processed by multivariate curve resolution - ...
Linear algebra-based controller for trajectory tracking in mobile robots with additive uncertainties estimation
(Oxford University Press, 2019-05)
This paper addresses trajectory tracking problem in mobile robots considering additive uncertainties. The controller design method is based on linear algebra theory. Numerical estimation techniques are used to estimate the ...
Second-order multivariate calibration with the extended bilinear model: Effect of initialization, constraints, and composition of the calibration set on the extent of rotational ambiguity
(John Wiley & Sons Ltd, 2020-03-15)
Extended bilinear modeling is popular in second-order multivariate calibration, particularly when the matrix data for each sample are of chromatographic origin. Since elution time profiles vary across samples, in both shape ...
A monocular wide-field vision system for geolocation with uncertainties in urban scenes
(IOP Publishing, 2020-06-22)
In engineering applications related to video surveillance, the use of monocular omnidirectional cameras would reduce costs and complications associated with infrastructure, installation, synchronization, maintenance and ...
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 ...
A new parameter for measuring the prediction uncertainty produced by rotational ambiguity in second-order calibration with multivariate curve resolution
(American Chemical Society, 2020-05-28)
Multivariate curve resolution-alternating least-squares (MCR-ALS) is the model of choice when dealing with matrix data that cannot be arranged into a trilinear three-way array, that is, mostly from chromatographic origin ...
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 ...
