A discussion of bias in magnetotelluric responses
(Society of Exploration Geophysicists, 2009-07)
Magnetic-field noise biases magnitudes of magnetotelluric response functions such as resistivity, impedance, and the induction vector (tipper). This is particularly severe in the so-called dead band between about 1- and ...
A Bayesian bias updating procedure for automatic adaptation of soft sensors
(Pergamon-Elsevier Science Ltd, 2021-04)
Straightforward bias updating procedures for online adjustment of soft sensors (SS) are of interest for industrial processes in which quality or production variables cannot be measured online. This work proposes a Bayesian ...
Description of electric field-dependent dielectric permittivity in PMN ceramics
(2019-01-01)
The temperature dependences of the linear and nonlinear components of the dielectric permittivity of PMN ceramics were determined as a function of bias electric fields. The influence of the applied bias electrical field, ...
Día de menarquia, expectativa de fiesta y sesgo de memoria
(Sociedad Médica de Santiago, 2004-03)
The photoperiod and temperature were ruled out as
main factors of the annual menarche rhythm. Vacations associate to peaks and study periods to
troughs of menarche. Some months show contradictory behavior according to ...
Exchange bias perpendicular em multicamadas de IrMn/Co/Pd
(Universidade Federal de Santa MariaBrasilFísicaUFSMPrograma de Pós-Graduação em FísicaCentro de Ciências Naturais e Exatas, 2023-04-26)
Magnetic skyrmions are spin textures that can arise in thin films that exhibit the Dzyaloshinskii–Moriya interaction. Such interaction emerges from symmetry breaking at the interface
between a ferromagnetic material and ...
Second-order biases of maximum likelihood estimates in overdispersed generalized linear models
(2001)
In this paper, we derive general formulae for second-order biases of maximum likelihood estimates in overdispersed
generalized linear models, thus generalizing results by Cordeiro and McCullagh (J. Roy. Statist. Soc. Ser. ...
Home Bias e investimentos
(Centro de Estudos em Finanças (GVcef), 2015)
O presente artigo se destina a apresentar uma análise da concentração do portfólio de ações de investidores brasileiros, nas próprias empresas onde trabalham. Essa análise se concentrará nas ações que estes investidores ...
