Degradação do cabelo humano causada pelo uso de alisantes contemporâneos e outros processos químicos
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Química - PPGQCâmpus São Carlos, 2017-10-26)
In the XXI century, there has been an increasing research on cosmetic agents including chemical changes. Consequently, new smoothers have come up, such as: carbocisteine, glyoxylic acid and the forbidden formaldehyde. ...
Nonparametric estimation of a surrogate density function in infinite-dimensional spaces
(Taylor & Francis Ltd, 2012-06)
A density function is generally not well defined in functional data context, but we can define a surrogate of a probability density, also called pseudo-density, when the small ball probability can be approximated by the ...
Robust estimators in semi-functional partial linear regression models
(Elsevier Inc, 2017-02)
Partial linear models have been adapted to deal with functional covariates to capture both the advantages of a semi-linear modelling and those of nonparametric modelling for functional data. It is easy to see that the ...
Bayesian Estimation Of A Skew-student-t Stochastic Volatility Model
(SPRINGERDORDRECHT, 2015)
The smoothing hypothesis, stock returns and risk in Brazil
(2011)
Income smoothing is defined as the deliberate normalization of income in order to reach a desired trend. If the smoothing causes more information to be reflected in the stock price, it is likely to improve the allocation ...
Komagataeibacter rhaeticus grown in sugarcane molasses-supplemented culture medium as a strategy for enhancing bacterial cellulose production
(2018-10-15)
Komagataeibacter rhaeticus, a bacterium isolated from Kombucha tea, was used to produce bacterial cellulose (BC) through its cultivation in a static sugarcane molasses (SCM) supplemented-culture medium (totally or partially), ...
Diferencias entre la aplicación de onda viajera con wavelet y con differentiator-smoother
(Universidad de los AndesIngeniería EléctricaFacultad de IngenieríaDepartamento de Ingeniería Eléctrica y Electrónica, 2022)
Actualmente se comercializan relés que usan la protección de onda viajera. Uno de los pasos necesarios para implementar este algoritmo es eliminar las señales en la banda de frecuencia de 60Hz y lograr detectar el tiempo ...
