We evaluate two density estimators based on the quantile variance and quantile-mean covariance estimated by bootstrap. review previous developments estimation related to quantiles. Monte Carlo simulations for different data generating processes, sample sizes, other parameters show that perform well in comparison benchmark non-parametric kernel estimator. Some of explored smoothing techniques pr...

Themophysical properties of high temperature molten materials are mczsured using an electrostatic levitator in combination with several diagnostic devices. An objective of this study is to find the limitation of the earth-based measurements in order to evaluate the necessity of similar measurements in space. It is found that the hemispherical total emissivity, specific heat, specific volume, de...

We examine the effect of a more realistic Earth matter density model which takes into account of the local density variations along the baseline of a possible 2100 km very long baseline neutrino oscillation experiment. Its influence to the measurement of CP violation is investigated and a comparison with the commonly used global density models made. Significant differences are found in the comp...

We introduce a new approach for nonparametric spectral density estimation based on the subsampling technique, which we apply to important class of nonstationary time series. These are almost periodically correlated sequences. In contrary existing methods, our technique does not require demeaning data. On simulated data examples, compare estimator function with classical one. Additionally, propo...

OBJECTIVE To investigate whether static ocular counterroll (OCR) gain is reduced during viewing of an earth-fixed vs a head-fixed target. METHODS Twelve healthy individuals were recruited. The target consisted of a red fixation cross against a grid pattern at a viewing distance of 33 cm. The target was mounted on a wall (earth fixed) or was coupled to the head (head fixed). Changes in mean to...
