Multiple Concentric Annuli for Characterizing Spatially Nonuniform Backgrounds
A method is presented for estimating the background at a given location on a sky map by interpolating the estimated background from a set of concentric annuli which surround this location. If the background is nonuniform but smoothly varying, this method provides a more accurate (though less precise) estimate than can be obtained with a single annulus. Several applications of multi-annulus back...
متن کاملCouette-Poiseuille Flow of Non-Newtonian Fluids in Concentric Annuli
Two types of laminar flows of non-Newtonian fluids in annuli with stationary outer cylinder are analysed from the viewpoint of existence of an exact analytical or almost exact analytical (quasisimilarity) solution relating volumetric flow rate and axial pressure gradient. The exact analytical solution is derived for the Vocadlo (RobertsonStiff) fluids when flow is caused simultaneously by the i...
متن کاملOptimization of large field tritan stimuli using concentric isoluminant annuli.
Large, nominally isoluminant chromatic gratings containing a short-wavelength component are prone to luminance contrast intrusions due to retinal inhomogeneity, especially as a result of the uneven distribution of macular pigment. Isoluminance is usually determined for a relatively small, central area, but a significantly larger stimulus cannot be isoluminant across the whole field, largely due...
متن کاملPhase-shifting algorithms for nonlinear and spatially nonuniform phase shifts
In phase-shifting interferometry spatial nonuniformity of the phase shift gives a significant error in the evaluated phase when the phase shift is nonlinear. However, current error-compensating algorithms can counteract the spatial nonuniformity only in linear miscalibrations of the phase shift. We describe an errorexpansion method to construct phase-shifting algorithms that can compensate for ...
متن کاملSpatially Nonuniform Scaling Functions for High Contrast Images
An algorithm is presented that scales the pixel intensities of a computer generated greyscale image so that they are all displayable on a standard CRT. This scaling is spatially nonuniform over the image in that different pixels with the same intensity in the original image may have different intensities in the resulting image. The goal of this scaling transformation is to produce an image on t...
