The possibility that researchers should be able to obtain data from all cases is questionable. There a need; therefore, this article provides probability and non-probability sampling. In paper we studied the differences similarities of two with approach more fritter away time, cost sufficient energy required throughout sample observed. pair shows between them, different articles were reviewed c...

Abstract In this paper, we present new regularized Shannon sampling formulas which use localized with special window functions, namely Gaussian, $$\mathrm B$$ B -spline, and $$\sinh $$ sinh -type functions. contrast to the classical series, possess an exponential decay are numerically robust ...
