The oxidation of organic compounds and color removal of a synthetic dyeing effluent when treated with a combination of Fenton’s Reagent and biological oxidation in a sequencing batch reactor was evaluated in this work. A central composite design approach was used to find the best conditions of temperature, hydrogen peroxide and ferrous ion concentrations that maximize color and dissolved organi...

–Fuzzy filter is a filter technique for the removal of random impulse noise in color video. By working with different successive filtering steps, a very good tradeoff between detail preservation and noise removal is obtained. So, to noise is filtered step by step. In each step, noise pixels in color frame are detected using fuzzy rules, which are very useful for the processing of human knowledg...

The chemical coagulation methods have been using successfully for treatment of textile wastewaters which have high color, COD and TOC contents. The coagulants have adsorption capability and constitute hydroxide compounds with dissolved substances in colored wastewaters.The greatest advantage of the coagulation method is to decrease further COD values than the other methods. The disadvantages of...

We have investigated the image type full-color computer-generated hologram that has full parallax and can be reconstructed with three color LEDs. The object of the hologram is processed from 3D computer graphics polygon data and has shaded surface with hidden surface removal. The optical reconstructed image from the printed hologram is evaluated. © 2011 Optical Society of America OCIS codes: 09...

Abstract : In this paper a new class of filters designed for the removal of impulsive noise in color images is presented. The proposed filter class is based on the nonparametric estimation of the density probability function of pixels in a sliding filtering window. The comparison of the new filtering method with the standard techniques used for impulsive noise removal, indicates good noise remo...

In the process of moving target detection, moving objects and their shadows are often extracted both. It leads to the failure of moving target positioning, segmentation, tracking and classification in the moving-object detection. Thus the shadow removal is an important task in the intelligent monitoring system. In the process of shadow removal, using color features to detect shadow is easy to c...

Sugar industry is an oldest accommodates industry in the world. It required and discharges a large amount of water for processing. Removal of chemical oxygen demand and color through the electrochemical process including hybrid iron and aluminum electrode was examined for the treatment of cane-based sugar industry wastewater. Most favorable condition at pH 6.5, inter-electrode gap 20 mm, curren...

Floral-color Changes Floral-color changes are common among the angiosperms. At least three non-exclusive hypotheses have been proposed to explain these changes: 1. Once flowers are adequately pollinated, further pollinator visits impair reproduction by deposition of self-pollen, dislodging of pollen, or damage to floral parts. 2. Color changes mark flowers that have been depleted of their rewar...
