Real-time cinematic relighting of large, forest ecosystems remains a challenging problem, in that important global illumination effects, such as leaf transparency and inter-object light scattering, are difficult to capture, given tight timing constraints and scenes that typically contain hundreds of millions of primitives. A solution that is based on a lattice-Boltzmann method is suggested. Ref...

Simultaneous broadband absorption and polarization conversion are crucial in many practical applications, especially terahertz communications. Thus, actively tunable metamaterial systems can exploit the graphene-based nanomaterials derived from renewable resources because of flexible surface conductivity selective permeability at frequencies. In this paper, we propose a active bifunctional meta...

[1] This study develops an analytical four-stream isosector approximation for solar radiative transfer in a homogeneous canopy, based on the approximation of four spherical sectors of isotropic intensities (constant values for light intensities). Compared to results from a multilayer radiative transfer model, the four-stream isosector approximation substantially improves the accuracy in calcula...

Background and Aims: Grapevine shoot growth light utilization are typically adjusted through the use of canopy management strategies that adapted to local climate. In this study, we analyze effects a pergola (PER) single-curtain training system (SCT) on microclimate, interception, photosynthetic capacity, assimilate distribution ‘Miguang’ grape in rainy region China. Methods Results: We measure...

Abstract Powder bed fusion (PBF) of ceramics is often limited because the low absorptance ceramic powders and lack process understanding. These challenges have been addressed through a co-development customized laser capabilities. The starting powder made mix pure alumina granules, to which metal oxide dopant added increase absorptance. performance different granules parameters depends on large...

The passive thermal control of a satellite consists establishing the necessary parameters involved in process heat transfer by radiation and conduction order to delimit range temperatures which different components will be exposed. If obtained implies that elements are unable cope with, therefore, an external is demanded. This work deals with programming equilibrium problem taken into considera...
