Variable Transmission Silicate Glasses Sensitive to Sunlight

Science, 1962
The process of variable transmission in silicate glasses has been accomplished by optically pumping color centers by electron transfer from europium (II) or cerium (III) which absorb sunlight at higher energies than the color center. Absorbed energy quickly pumps the visible color center band to a maximum.

The joint influence of estimation of sensitive variable under measurement error and non-response using ORRT models

Journal of Statistical Computation and Simulation, 2022
This paper addresses three important issues of survey sampling: social desirability bias, measurement error and non-response simultaneously. We suggested a combined family of regression-cum-exponential estimators for estimating the population mean of ...

Estimation of mean of a sensitive variable using efficient exponential-type estimators in stratified sampling

Journal of Statistical Computation and Simulation, 2021
Sousa et al. [Improved mean estimation of a sensitive variable using auxiliary information in stratified sampling. J Stat Manage Syst. 2014;17(5–6):503–518] presented a ratio estimator for mean estimation in stratified sampling using an additive ...

Estimation of finite population distribution function of sensitive variable*

Communications in Statistics - Theory and Methods, 2021
The finite population proportion of a sensitive characteristic is estimated indirectly by using Randomized Response (RR) Techniques (RRT’s) pioneered by Warner (1965) followed by several other RRT’s in the literature.
