The most common solutions to the light transport problem rely on either Monte Carlo (MC) integration or density estimation methods, such as uni& bi-directional path tracing or photon mapping. Recent gradient-domain extensions of MC approaches show great promise; here, gradients of the final image are estimated numerically (instead of the image intensities themselves) with coherent paths generat...

in present work, we have calculated the electronic properties including density of states and electron density for gan, inn and inxga1-xn  in wurtzite phase for x=0.5. the study is based on density functional theory with full potential linearized augmented plane wave method by generalized gradient approximation for calculating electronic properties. in this report we concluded that inxga1-xn ba...

Log-density gradient estimation is a fundamental statistical problem and possesses various practical applications such as clustering and measuring nongaussianity. A naive two-step approach of first estimating the density and then taking its log gradient is unreliable because an accurate density estimate does not necessarily lead to an accurate log-density gradient estimate. To cope with this pr...
