OB associations are important probes of recent star formation and Galactic structure. In this study, we focus on the Auriga constellation, an region due to its numerous young stars, star-forming regions open clusters. We show using \textit{Gaia} data that two previously documented associations, Aur OB1 OB2, too extended in proper motion distance be genuine encouraging us revisit census with mod...

estimation of weed damage threshold is essensial in site-specific weed control programs. this experiment was conducted to determine the spatial distribution of weeds damage threshold in two wheat feilds. data related to weed biomass and crop yield were collected from sampling at 120 and 135 points of the first and second fields respectively based on a 4×4 m grid at research field of agricultura...

A method is presented that can render glossy reflections with arbitrary isotropic bidirectional reflectance distribution functions (BRDFs) at interactive rates using texture mapping. This method is based on the well-known environment map technique for specular reflections. Our approach uses a singleor multilobe representation of bidirectional reflectance distribution functions, where the shape ...

Environment maps, like texture maps or any other maps consisting of discretely stored data have to be properly filtered, if they are being resampled in the process of rendering an image. For environment maps, this is especially important, as the sampling rate is subject to extreme changes due to the curvature of the reflecting surfaces. However, for the same reason, the antialiasing is especial...
