Application of adaptive sampling in fishery part 1: Adaptive cluster sampling and its strip designs
Abstract: The precision of conventional sampling designs is not usually satisfactory for estimating parameters of clump and rare populations. Many of fish species live in school and disperse all over a vast area like a sea so that they are rare compare to their habitats. Theory of a class of sampling designs called adaptive sampling designs has rapidly grown during last decade which solv...

متن کاملSampling Rate Conversion in the Discrete Linear Canonical Transform Domain
Sampling rate conversion (SRC) is one of important issues in modern sampling theory. It can be realized by up-sampling, filtering, and down-sampling operations, which need large complexity. Although some efficient algorithms have been presented to do the sampling rate conversion, they all need to compute the N-point original signal to obtain the up-sampling or the down-sampling signal in the tim...
متن کاملRow and Column Elimination Sampling Design +1 and its Efficiencies
Extended Abstract. It is a traditional way in biological, sociological, agricultural and geological studies to partition a geographical area into quadrats and then take a sample of them by a particular sampling design. We study the relevant characteristic of quadrats to estimate a parameter of the population. We suppose that the variable of interest has a positive spatial autocorrelation. Sampl...
متن کاملMicrofiltration sampling in rats and in cows: toward a portable device for continuous glucocorticoid hormone sampling.
To monitor temporal patterns of glucocorticoids hormones in living animals, most often blood samples are collected. Blood sampling is invasive and subjects may find it--in particular--unpleasant when multiple samples are collected. We have developed a microfiltration collection device (MCD) sampling continuously, pulse-free, over a selected period of time, with minimum invasiveness as the devic...
