The rat whisker system may be a good model for approaching the design of robust robotic active sensing and exploratory systems. Here we examine how rats use their whiskers (vibrissae) during free exploratory behavior and during a texture discrimination task. Results show that during free exploration, the rat rhythmically moves its head to place its small (micro) vibrissae on the surfaces it is ...

The surface properties of alloys can be improved by coating their surfaces and adding a micro-texture. effect on the alloy composite coatings textured has not been addressed in previous studies. In this study, micro-texture was added to WC+Co AlCrN/AlTiSiN coating. influence micro-texture’s geometric parameters its lifespan were studied detail. First, hardness phases various micro-textured anal...

Automated scanning electron microscopic studies got exclusive acceptance in identification of various mineral phases; its classification and characterization based on their composition abundance semi quantitative manner. Nowadays, these techniques are adopted understanding poorly crystalline amorphous materials to reveal the actual assemblages. Primary phases five ferromanganese crust nodule sa...

We present a novel optimization framework for unsupervised texture segmentation that relies on statistical tests as a measure of homogeneity. Texture segmentation is formulated as a data clustering problem based on sparse proximity data. Dissimilarities of pairs of textured regions are computed from a multi{scale Gabor lter image representation. We discuss and compare a class of clustering obje...

Achieving a visually appealing experience for the user interaction with photo-realistic digitized micro-fiber materials is a challenging task. While state-of-the-art high-quality fabric modeling techniques rely on complex micro-geometry representations that are computationally expensive and not well-suited for interactive rendering, previous interactive reflectance models reach a speed-up at th...

To investigate the flotation separation behavior of petalite and quartz, various methods were employed in this study. These included micro-flotation experiments, a contact angle analysis, zeta potential Fourier transform infrared spectroscopy (FTIR), X-ray photoelectron (XPS) to explore mechanism modified ether amine reagent (L0-503) for quartz under weakly alkaline conditions. The test results...

A profile of Guanajibo clay (Plinthic Kandiudults) was evaluated to determine the ironstone content in horizons and its chemical, physical mineralogical properties. The mineralogy characterized by X-ray diffraction (XRD) iron aluminum oxide determined selective dissolution, using citrate-bicarbonate dithionite (CBD) ammonium oxalate (OX) extractions. Soil color ground were with Munsell charts. ...

The Upper Cretaceous Sannae-Eonyang granite crystallized approximately 73 Ma and hosted the Sannae W-Mo deposit in west Eonyang amethyst east. contained textural zones of miarolitic cavities unidirectional solidification texture (UST) quartz. UST rock sampled mine consisted (1) early cavity-bearing aplitic granite, (2) co-crystallization feldspars quartz a granophyric (3) latest growth larger c...
