The spatial coherence (visibility) and the beam size of undulator radiation are measured with a Young's interferometer and a wire scanner in the soft X-ray region, of about 40 200 eV.
It is important to note that both the angular carrier frequency and the spatial fringe visibility dictated by the coherence envelope are set by θ ⇀, and thus a fixed number of fringes are visible for a given spectral bandwidth δk.
The analysis is based on estimating the individual multipath components, and it focuses on their spatial area of visibility.
Based on the dynamic spatial database, a visibility optimization approach that can efficiently reduce the overall geometry is presented.
An analysis of measured channels that explicitly includes finite spatial areas of visibility of the multipath components is superior to the classic analysis that attributes spatial dynamics to interference of the multipath.
The results revealed that student perceptions rely heavily on spatial attributes, specifically visibility and furniture, and ambient attributes, specifically air quality and temperature, which are highly impacted by the design, management and maintenance of classrooms.
EEG and MEG were recorded while participants reported the spatial location and visibility of a briefly presented target.
Overall, the results show that the perception of speed is influenced by spatial variations in visibility, and they strongly suggest that this is due to the relative speed contrast between the visible and covert areas within the scene.
Such arrays serve as secure, robust and low-visibility spatial or transform domain spread-spectrum watermarks [10].
However, it is of limited value in evaluation of early breast cancer because of limited spatial resolution, non-visibility of tumors with low F-FDG avidity, and low specificity [ 7].
Early work on lesbian urban spaces documented distinctions between gay men's and lesbians' visibility and spatial strategies and attempted to account for the marked differences between the two groups.
