The image quality parameters to be determined using this phantom are (i) recovery coefficients for the differently sized rods, indicative of spatial resolution, (ii) spillover of activity into the cold air and water compartments, expressing the scatter performance, and (iii) uniformity of measured activity in the background compartment that indicates the signal-to-noise ratio.
Lack of uniformity of measured elements makes it impossible to incorporate the majority of these studies into a meta-analysis.
We noticed that the noise of each time series analysed (e.g., absence of periodicity, presence of instrumental errors and non-uniformity of measures) did not influence the TVA algorithm's forecasting capability.
(3) The distance from front footprint to ipsilateral hind footprint was also used to measure uniformity of step alternation.
It has been conjectured that a frame-spectral measure must be translationally absolutely continuous, which is a criterion describing the local uniformity of a measure on its support.
The remarkable uniformity of weights and measures throughout the Indus lands, as well as the development of such presumably civic works as the great granaries, implies a strong degree of political and administrative control over a wide area.
The composition of the copolymer obtained is in good agreement with predicted values and the uniformity of composition was measured for the entire molecular mass distribution.
Significance of mean vectors determined by Rayleigh's Z and uniformity of vector distribution measured by Rao's Spacing test.
The three corneas (C1 3) also produced an equatorial reflection, caused by the uniformity of fibril diameters (measuring on average 33 ± 2 nm) and the regular Bragg spacing of collagen fibrils (51 ± 5 nm), within each lamella of the corneal stroma.
The degree of uniformity needed to measure of the amount of variation in the power on the receiving surface has previously been defined as the ratio of the maximum to minimum received power levels in an indoor optical wireless communication system [15].
