Boyacı, Ezel; Gorynski, Krzysztof; Mirnaghi, Fatemeh; Souza-Silva, Erica A.; Hein, Dietmar; Pawliszyn, Janusz (2015-05-11)
In chemical analysis, sample preparation is frequently considered the bottleneck of the entire analytical method. The success of the final method strongly depends on understanding the entire process of analysis of a particular type of analyte in a sample, namely: the physicochemical properties of the analytes (solubility, volatility, polarity etc.), the environmental conditions, and the matrix components of the sample. Various sample preparation strategies have been developed based on exhaustive or non-exha...

Sample design and allocation for random digit dialling
Ayhan, HO; İslam, Muhammed Qamarul (Springer Science and Business Media LLC, 2005-10-01)
Sample design and sample allocation methods are developed for random digit dialling in household telephone surveys. The proposed method is based on a two-way stratification of telephone numbers. A weighted probability proportional to size sample allocation technique is used, with auxiliary variables about the telephone coverage rates, within local telephone exchanges of each substrata. This makes the sampling design nearly "self-weighting" in residential numbers when the prior information is well assigned. ...
