Estimating the concentration of nucleation mode aerosol particles over South Africa using satellite remote sensing measurements
(AIP Publishing, 2013)In this work satellite based observations were used to estimate the concentration of nucleation mode aerosols over South Africa. The nucleation mode aerosols can not be detected directly with satellite instruments since ... -
Estimating the number of equal components for two high-dimensional mean vectors
(Taylor and Francis, 2020)In this article, we propose a new method for estimating the number of equal components m0 of two m-dimensional population means when m is large. The proposed method can be used to estimate the number of equally expressed ... -
Estimation of a copula when a covariate affects only marginal distributions
(Wiley, 2015)This paper is concerned with studying the dependence structure between two random variables Y1 and Y2 in the presence of a covariate X, which affects both marginal distributions but not the dependence structure. This is ... -
Estimation of bid-ask prices for options on LIBOR based instruments
(Elsevier, 2016)Interest rate options are the most liquid traded derivatives in the markets. We observe the following from the markets: (i) Market dealers usually quote the mid-price. The mid-price is a subjective and hypothetical price. ... -
Estimation of human body concentrations of DDT from indoor residual spraying for malaria control
(Elsevier, 2012)Inhabitants of dwellings treated with DDT for indoor residual spraying show high DDT levels in blood and breast milk. This is of concern since mothers transfer lipid-soluble contaminants such as DDT via breastfeeding to ... -
ETFE-g-pentafluorostyrene: functionalization and proton conductivity
(Elsevier, 2015)In this study we propose a relatively simple and versatile method for the preparation of a polyelectrolyte membrane based on poly(pentafluorostyrene) (PFS) owing proton exchange functionalities for proton conducting ... -
