Application of partial least square regression to differential scanning calorimetry data for fatty acid quantitation in olive oil
(Elsevier, 2011-08)
A chemometric approach based on partial least (PLS) square methodology was applied to unfolded differential scanning calorimetry data obtained by 63 samples of different vegetable oils (58 extra virgin olive oils, one olive ...
Nonparametric Bayesian Modeling and Estimation of Spatial Correlation Functions for Global Data
(INT SOC BAYESIAN ANALYSIS, 2021)
We provide a nonparametric spectral approach to the modeling of correlation functions on spheres. The sequence of Schoenberg coefficients and their associated covariance functions are treated as random rather than assuming ...
On mean value solutions for the Helmholtz equation on square grids

Adaptive observer design for parabolic partial differential equations
(2017)
This thesis addresses the observer design problem, for a class of linear one-dimensional parabolic Partial Differential Equations, considering the simultaneous estimation of states and parameters from boundary measurements. ...
Comparative study of wine tannin classification using Fourier transform mid-infrared spectrometry and sensory analysis
(SOC APPLIED SPECTROSCOPY, 2007)
Wine tannins are fundamental to the determination of wine quality. However, the chemical and sensorial analysis of these compounds is not straightforward and a simple and rapid technique is necessary. We analyzed the ...
Outlier detection with data mining techniques and statistical methods
(Institute of Electrical and Electronics Engineers Inc., 2019)
The outlier detection in the field of data mining and Knowledge Discovering from Data (KDD) is capturing special interest due to its benefits. It can be applied in the financial area; because the obtained data patterns can ...
Classification of metabolic syndrome subjects and marathon runners with the k-means algorithm using heart rate variability features
(INSTITUTE OF ELECTRICAL AND ELECTRONICS ENGINEERS INC., 2016-08-30)
In this paper, we have applied the k-means clustering algorithm to classify three study groups (people with metabolic syndrome, marathon runners, and sedentary subjects) that underwent a 5-sample 2-hour oral glucose tolerance ...
Uma formulação variacional do tipo mínimos quadrados para equações diferenciais ordinárias aplicável ao tratamento numérico de problemas de controle ótimo
(Universidade Federal de Minas GeraisUFMG, 1996-10-10)
The equivalence between an initial value problem described by ordinary differential equations and the extremum of a least square type functional is showed to happen under certain regularity condition hypothesis. This allows ...
Modelagem fracionária da dinâmica da COVID-19
(Universidade Estadual Paulista (Unesp), 2022-02-24)
Este trabalho apresenta uma revisão de modelos matemáticos que tratam da dinâmica do espalha- mento da COVID-19, além disso apresenta aspectos gerais da teoria do Cálculo de Ordem Não Inteira, tradicionalmente conhecido ...
