We present a method for the integration of illumina tion constraints within a deformable model framework These constraints are incorporated as nonlinear holo nomic constraints in the Lagrange equations of motion governing the deformation of the model For improved numerical performance we employ the Baumgarte sta bilization method Our methodology is general and can be used for a broad range of i...

this study aimed to determine the effects of different shading ratio and covers on “sultana seedless” table grape quality and storability. grapevines were covered at the veraison stage with 3 shading nets (0, 35, and 75% shading), which were then replaced with covering materials including polypropylene cross-stitch (pc), life pack (lp) and mogul (mg), just before harvest. harvested grapes in al...
