One of the basic difficulties with interactive walkthroughs is the high quality rendering of object surfaces with non-diffuse light scattering characteristics. Since full ray tracing at interactive rates is usually impossible, we render a precomputed global illumination solution using graphics hardware and use remaining computational power to correct the appearance of non-diffuse objects on-the...

The use of molten aluminum droplets is investigated for potential application to Precision Droplet-Based Net-Form Manufacturing (PDM). In the proposed application, final structural components are made from the raw stock in one integrated operation by depositing molten metal droplets, layer after layer, via computer information. This work investigates the feasibility of the proposed technology b...

We prove that the 3-D free-surface incompressible Euler equations with regular initial geometries and velocity fields have solutions which can form a finite-time “splash” (or “splat”) singularity first introduced in Castro et al. (Splash singularity for water waves, http://arxiv.org/abs/1106.2120v2, 2011), wherein the evolving 2-D hypersurface, the moving boundary of the fluid domain, self-inte...

Splashing of splat particles is one of the most important phenomena in industrial processes such as thermal spray coating. The data relative to the degree of splashing of splats sprayed with a normal angle are commonly characterized by the Weibull distribution function. In this present study, an effort has been made to show that the Burr distribution is better than the Weibull distribution for ...

As verified by literature, heat-treatments of as-atomized Al-alloy powders before cold spraying, result in microstructural homogenization and deposition efficiency increment. So far, a straightforward correlation between powder strength consequences for the performance spraying deposit properties is still missing. This work thus provides reliable analyses strengths annealed states to calculatio...

Abstract Native to Southeast Asia, the spotted‐wing drosophila ( Drosophila suzukii ) has become a major pest of small fruit crops in Americas and Europe because females can oviposit ripening fruit. Currently, D. management relies heavily on chemical control; thus, more sustainable approaches like attract‐and‐kill need be evaluated reduce insecticide use. In previous studies, HOOK SWD, an produ...
