This research article, presents a ratio estimator for the estimation of finite population mean of the study variable under double sampling scheme when there is unusually low and unusually high values and analyzes their properties. The expressions for bias and MSE of the proposed estimator are derived up to first order of approximation. Also efficiency conditions are carried out with the other e...

A double-sampling highpass delta-sigma modulator (HPDSM) with inherent frequency translation is presented. The switched-capacitor highpass filter with double-sampling not only minimizes the number of capacitors required in the feedback network but also enables chopper stabilization which makes the modulator immune to 1/f noise and DC offset. A first-order prototype HPDSM with 3bit quantization ...

The noise performance of digital correlated double sampling (DCDS) for readout of charge coupled devices (CCD) with dominant white noise is presented. The trade-offs between analogue and digital signal filtering and the impact on the sampling rate are investigated and numerically simulated for realistic systems. The results can be used to select the signal bandwidth, the settling accuracy and t...

let  be a banach algebra. let  be linear mappings on . first we demonstrate a theorem concerning the continuity of double derivations; especially that all of -double derivations are continuous on semi-simple banach algebras, in certain case. afterwards we define a new vocabulary called “-higher double derivation” and present a relation between this subject and derivations and finally give some ...

In this study we investigated the larval dispersal associated with larval predation in experimental populations of Chrysomya albiceps and Cochliomyia macellaria. Frequency distribution of sampling units (G test) in the substrate was used to evaluate variation in larval dispersal. An experimental acrylic channel (1 x 0.1 x 0.2 m) covered with wood shavings was used to observe larval dispersal pr...
