An improved ECG-derived respiration method using kernel principal component analysis
Recent studies show that principal component analysis (PCA) of heart beats generates well-performing ECG-derived respiratory signals (EDR). This study aims at improving the performance of EDR signals using kernel PCA (kPCA). ...

Relationships between PCA and PLS-regression
(Elsevier Science, 2014-01)
This work aims at comparing several features of Principal Component Analysis (PCA) and Partial Least Squares Regression (PLSR), as techniques typically utilized for modeling, output prediction, and monitoring of multivariate ...
Detecção de falhas em processos químicos contínuos : uma abordagem via ensemble learning e inferência bayesiana
(Universidade Federal de Minas GeraisBrasilENG - DEPARTAMENTO DE ENGENHARIA QUÍMICAPrograma de Pós-Graduação em Engenharia QuímicaUFMG, 2019-02-27)
A fault is an unwanted event in any operation in a chemical industry. Its occurrence may cause safety, environmental and economic losses. Due to the complexity of chemical processes from one side, and the availability of ...
Sex type determination in papaya seeds and leaves using near infrared spectroscopy combined with multivariate techniques and machine learning
(2022-02-01)
Papaya trees (Carica papaya L.) can bear female, hermaphrodite, and male flowers. However, only the hermaphrodite type produces elongate fruit required and appreciated by the consumer market. Sex type determination is ...
Non-destructive genotypes classification and oil content prediction using near-infrared spectroscopy and chemometric tools in soybean breeding program
(2020-08-01)
In soybean (Glycine max L.) breeding programs, segregation is normally observed, and it is not possible to have replicates of individuals because each genotype is a unique copy. Therefore, near-infrared spectroscopy (NIRS) ...

(Nature Publishing GroupReino Unido, 2020)
The incidence of patients under 55 years old diagnosed with Prostate Cancer (EO-PCa) has increased
during recent years. The molecular biology of PCa cancer in this group of patients remains unclear.
Here, we applied ...
Stroke volume and cardiac output non-invasive monitoring based on brachial oscillometry-derived pulse contour analysis: Explanatory variables and reference intervals throughout life (3–88 years)
(Via Medica, 2020-03)
Background: Non-invasive assessment of stroke volume (SV), cardiac output (CO) and cardiac index (CI) has shown to be useful for the evaluation, diagnosis and/or management of different clinical conditions. Through pulse ...
