n this paper, Principal Component Analysis has been applied to investigate the spatial variability of errors in the INSAT derived quantitative precipitation estimates (QPE) over the Indian monsoon region, using daily rainfall a... see more

Occupation is a central concept in sociology and economics and individual change in occupation is of major importance to literatures on wage determination, human capital, careers and social mobility. The collection of occupational data in surveys, particu... see more

Mixed mode designs are receiving increased interest as a possible solution for saving costs in panel surveys, although the lasting effects on data quality are unknown. To better understand the effects of mixed mode designs on panel data we will examine it... see more

The Langmuir isotherm is a nonlinear regression model, being one of the most applied in adsorption studies. In this type of study, the data are collected over time, which can provide correlated errors; in addition, the collection is not always done in an ... see more

The subject of research is accurate temperature measurements by thermocouples whose legs undergone degradation during long term operation at high temperatures. The degradation rate is approximately proportional to the temperature of constant operation of ... see more

Attrition of sample members from a longitudinal survey can undermine the quality of the data and its research potential, especially when the sample members who drop out are different from those who do not. People who move house are more likely to drop out... see more

The signal transmission and position quality obtained by GNSS positioning directly depends on the time control. The atomic clocks aboard the satellites are responsible for this control. In this research, the satellites clock errors of GPS are studied, usi... see more

Meshfree methods o?er the potential to relieve the scientist from the time consuming grid generation process especially in cases where localized mesh re?nement is desired. Moving least squares (MLS) methods are considered such a meshfree technique. The ps... see more
