Conventional Photometric Stereo (PS) techniques are usually based on the assumption that the light sources are assumed sufficiently far from the object that all incoming light can be modeled using parallel rays. Meanwhile, for near-field lighting conditions the light sources are close to the object so the parallel ray model cannot be used. To determine the surface normal for each point on the o...

Dimensional Finite Element Model for Pollutant A Two Transport out of Dumped Disposal sites

Luminous-efficiency functions for small fields were measured with flicker photometry and heterochromatic brightness-matching methods for the same two subjects. For the larger stimuli (22.9 and 11.5'), the luminous-efficiency functions differed between the two methods. Those obtained by flicker photometry showed a simple narrow shape, whereas those obtained by heterochromatic brightness matching...

A catalog of gamma-ray sources based on photons with energies greater than 1 GeV has been developed from observations taken by the EGRET instrument o f the Compton Gamma Ray Observatory. The data are taken from the 4.5 years of observation available in the public data archive. We emphasize sources which are detected using the entire database without regard to any possible transient o r v ariabl...

We discuss point sources foregrounds for the MAP experiment. We consider several possible strategies for removing them and we assess how the statistics of the CMB signal are affected by the residual sources. Assuming a power law distribution for the point sources, we propose a method aimed to determine the slope of the distribution from the analysis of the moments of the observed maps. The same...
