Damage Detection Based on Electromechanical Impedance Principle and Principal Components
(2014-01-01)
This paper presents a novel time domain approach for Structural Health Monitoring (SHM) systems based on Electromechanical Impedance (EMI) principle and Principal Component Coefficients (PCC), also known as loadings. ...

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). ...
Minimum number and best combinations of harvests to evaluate accessions of tomato plants from germplasm banks
(Genetics and Molecular Biology, 2019)
Multivariate morphometrics and allometry and allometry in a polymorphic ant
(Birkhauser Verlag Ag, 1994-01-01)
In this paper we describe how morphological castes can be distinguished using multivariate statistical methods combined with jackknife estimators of the allometric coefficients. Data from the polymorphic ant, Camponotus ...
Tranformada wavelet e redes neurais artificiais na análise de sinais relacionados à qualidade da energia elétrica
(Universidade Federal de Santa MariaBREngenharia ElétricaUFSMPrograma de Pós-Graduação em Engenharia Elétrica, 2009-02-10)
This work presents a different method for power quality signal classification using the principal components analysis (PCA) associated to the wavelet transform (WT). The standard deviation of the detail coefficients and ...
Principal component analysis of breeding values for growth and reproductive traits and genetic association with adult size in beef cattle
(Amer Soc Animal Science, 2016-12-01)
Principal component analysis was applied to evaluate the variability and relationships among univariate breeding values predicted for 9 weaning and yearling traits, as well as suggest functions of the traits that would ...
Principal component analysis in studies of substituent-induced carbon-13 chemical shifts of halogenated aliphatic compounds
(Elsevier Science BvAmsterdamHolanda, 2004)
