Using digital image processing and pattern recognition techniques, a supervised classification procedure of bamboo vascular bundles was developed and tested on polished cross sections of bamboo culms from four different species. Results obtained for same species samples were similar and were consistent with visual observations.

fe3o4-containing cotton-like mesoporous silica system (fe3o4@ncsm) was studied with regard to its performance towards the photodecolorization of bromothymol blue (btb) aqueous solution. the surface properties of the functionalized catalyst were analyzed by a series of characterization techniques like ftir, xrd, bet, sem and tem. the n2 adsorption–desorption analysis shows that the mesostructure...

Cellular materials, metallic bodies with gaseous voids, are a promising class of materials that offer high strength accompanied by a relatively low mass. Unfortunately, existing manufacturing techniques constrain a designer to a predetermined part mesostructure, material type, and macrostructure. In this paper, the authors document their design rationale for the selection of the Three-Dimension...

Recent measurement devices for the Bidirectional Texture Function (BTF) offer high parallel capture of the spatial varying reflectance data for material samples. We present an approach to use measurement data from homogenous materials or materials with stochastical mesostructure to obtain data samples for the fitting of BRDF models like CookTorrance. We applied this approach to measured samples...

The multi-scale, high-resolution and accurate structural modeling of rocks is a powerful means to reveal the complex failure mechanisms evaluate rock engineering safety. Due non-uniformity opacity rocks, describing their internal microstructure, mesostructure macro joints accurately, how model progressive fracture process, significant challenge. This paper aims build numerical method that can t...
