Very heterogeneous materials may need to be sampled in great bulk, amounting to 1 percent or more of the total.
Chemical streams in pipes need to be sampled with specially designed diverter probes that avoid turbulence and wall effects.
At the same time, it is important to recognize that mixed phases also frequently need to be sampled; gases dissolved in liquids and solids, particles suspended in liquids, and solid and liquid aerosols are some examples.
Music needs to be sampled before most people want to buy it.
These vertices are obvious sampling points, but their distance can be arbitrary, so that the edges need to be sampled.
Conformational sampling begins by identifying fragments from the rotamer library that are contained in the molecule of interest whose conformations need to be sampled.
According to a one-correlation t-test power analysis, 258 300 m2 plots delineated within Figure 3 would need to be sampled in order to sample 90% of the variation within the 25 ha area.
Moreover, instead of the usual strategy of using Fourier coefficients, we propose a new method based on wavelet descriptors to represent the shape of the path, where the points do not need to be sampled at a constant time interval.
As seen in Fig. 6, areas with a high estimation variance determine the area with high uncertainty of the estimation; therefore, these areas need to be sampled and studied further in prospective researches to decrease the uncertainty.
