Point-based rendering methods have proven to be effective for the display of large point cloud surface models, basically replacing global surface reconstruction with local surface estimations, for example, via splats or implicit functions. Crucial to their performance in terms of rendering quality and speed is the representation of the local surface patches. We present an approach that avoids a...

Through joined two sensitive methods solvation and cloud point extraction separated and determined micro amount of Ce(III) from aqueous solutions by using organic reagent 2,4-Dimethyl pentan-3-one (2,4-DMP) as extractant and non-ionic surfactant 1% TritonX-100 , the experimental study shows the solvation species of Ce+3 extracted into cloud point layer (CPL) have a wavelength for maximum absorb...

The extraction of building from the huge amount of point clouds with different local densities, especially in the presence of random noisy points, is still a formidable challenge. In this paper, we present a complete strategy for building extraction from terrestrial laser scanning data. First, a novel segmentation method is proposed to facilitate the task of building extraction. The points are ...

We present mechanistic characterization of alternating current cloud point extraction (ACPE) in a microchannel. ACPE is our original technique for on-chip extraction and preconcentration of membrane-associated biomolecules [1]. Joule heating of nonionic surfactant micellar solutions plays an important role in ACPE, but temperature of solutions during the extraction has not been investigated. In...

A new method for the determination of trace copper(II) in food samples by Cloud Point Extraction(CPE) combined with Flame Atomic Absorption Spectrometry(FAAS) is presented and evaluated. The method is based on the fact that hydrophobic complex of copper(II) with sodium diethyldithiocarbamate (DDTC) was formed at pH 6.0 and subsequently the hydrophobic complex was extracted into surfactant-r...

in this study, porous scaffolds from poly(d,l-lactic acid) have been prepared via liquid- liquid phase separation method in ternary system of polymer-1,4-dioxane-water. polymer dissolved in dioxane in 1.5, 2.5 and 5 % wt/v and the solvent/non-solvent ratios were 13/87, 15/85 and 17/83. cloud point curves prepared by visual turbidometry. in order to obtain porous scaffolds with inter-connected p...

A new feature point extraction algorithm which is used to match the satellite cloud image feature point is proposed. The new algorithm is proposed by combining corner detection with curvature scale space. The new algorithm can accurately extract the satellite cloud image corner points in different positions and directions. In order to accurately match the corner points of two source images, an ...

Biodiesel is usually produced from food-grade vegetable oil using trans-esterification process. As an effective factor on the biodiesel characteristics of the biodiesel is the kind of feedstock which is used, so finding a proper feedstock for using initially has an important role for different places. So, in this research, disposal substances of Capparis Spinosa are used as a feedstock for prod...
