A Practical Method for Estimation of Point Light-Sources [PDF]
Procedings of the British Machine Vision Conference 2001, 2001 We introduce a general model for point light-sources and show how the parameters of a source at finite distance can be estimated by shading on an object with known geometry and Lambertian reflectance. The parameters we estimate include not only the direction but also the location of the source.

Wiener–Hopf analysis of diffraction of acoustic waves by a soft/hard half-plane
Archives of Mechanics, 2010 In this paper, firstly, the far field due to a line source scattering of acoustic waves by a soft/hard half-plane is investigated. It is observed that if the line source is shifted to a large distance, the results differ from those of [16] by a ...

Distinguishing Dark Matter from Unresolved Point Sources in the Inner Galaxy with Photon Statistics
, 2015 Data from the Fermi Large Area Telescope suggests that there is an extended excess of GeV gamma-ray photons in the Inner Galaxy. Identifying potential astrophysical sources that contribute to this excess is an important step in verifying whether the ...

Agricultural Non-Point Source Pollution: Comprehensive Analysis of Sources and Assessment Methods [PDF]
AgricultureAgricultural non-point source pollution (ANPSP) significantly affects worldwide water quality, soil integrity, and ecosystems. Primary factors are nutrient runoff, pesticide leaching, and inadequate livestock waste management. Nonetheless, a thorough assessment of ANPSP sources and efficient control techniques is still lacking. This research delineates
