Snowball sample; Respondent-driven sampling; Snowball method; Snowballed sample

выборка типа "снежный ком"; эмпирическая выборка, не имеющая вероятностного обоснования, формируется, когда трудно очертить границы генеральной совокупности путем целенаправленного отбора экспертов и так называемых "редких элементов", которые после интервью могут указать следующий элемент и так далее (используется при изучении закрытых социальных групп - религиозных сект, банд и т.п.).

Nyquist Theorem

<communications> A theorem stating that when an analogue waveform is digitised, only the frequencies in the waveform below half the sampling frequency will be recorded. In order to reconstruct (interpolate) a signal from a sequence of samples, sufficient samples must be recorded to capture the peaks and troughs of the original waveform. If a waveform is sampled at less than twice its frequency the reconstructed waveform will effectively contribute only noise. This phenomenon is called "aliasing" (the high frequencies are "under an alias"). This is why the best digital audio is sampled at 44,000 Hz - twice the average upper limit of human hearing. The Nyquist Theorem is not specific to digitised signals (represented by discrete amplitude levels) but applies to any sampled signal (represented by discrete time values), not just sound. {Nyquist (http://geocities.com/bioelectrochemistry/nyquist.htm)} (the man, somewhat inaccurate).

Water sampling station

To enhance water quality monitoring in a drinking water network, water sampling stations are installed at various points along the network's route. These sampling stations are typically positioned at street level, where they connect to a local water main, and are designed as enclosed, secured boxes containing a small sink and spigot to aid in sample collection. Collected samples are analyzed for bacteria, chlorine levels, pH, inorganic and organic pollutants, turbidity, odor and many other water quality indicators.

In the United States, water sampling stations aid in public infrastructural safety in regards to water quality monitoring and help municipalities comply with federal and state drinking water regulations. New York City has 965 sampling stations that are distributed based on population density, water pressure zones, proximity to water mains and accessibility. The stations rise about 4½ feet above the ground and are made of heavy cast iron. Using these stations, the New York City Department of Environmental Protection (DEP) collects more than 1,200 water samples per month from up to 546 locations.
