Fast Dust Sand Image Enhancement Based on Color
Generally, the image appears dimmed in dusty sand and has low color contrast, poor visibility, and new high color tones of yellowish or reddish[3]–[8].to investigate the effect of washing on the water demand of 0/2 mm crushed sands in terms of rheological properties of mortars. The washing exper-iment results showed that the used washing procedure primarily reduced the amount of material below approximately 0.25 mm. Furthermore, the results from the PSD analysis of fines Possibilities of improving crushed sand performance in

Colour balance and contrast stretching for sand-dust
order to avoid the new colour deviation, the corrected image is converted from the RGB colour space to the HSV colour space and use the CLAHE to enhance the V component to improve the contrast. Then, a nonlinear gain function is defined to further adaptively sharpen the V component to enhance image details. Finally, the S component Innovations in wheat cleaning. 03.19.2012. By Mark Fowler. The process of converting wheat into flour has three fundamental steps — wheat cleaning, wheat conditioning, and of course, the milling process. All three steps impact the profitability and efficiency of the mill. However, the impact of the wheat cleaning process, with regards toInnovations in wheat cleaning World-Grain

Foam as a soil conditioner can transform the mechanical properties of the excavated natural muck and lubricate the interface between the cutting tools and muck, thus reducing the tools’ wear and promoting the efficiency of earth pressure balance (EPB) shield tunneling. This paper aims to explore the meso-mechanism of foam in improving the Improving the quality in cases of poor colour yield, dimensional stability, colour fastness or improper surface treatment. can be applied to textile materials as an alternative to conventional wet treatments such as stone washing, sand washing and bleaching for achieving the faded look and worn-out effects (Dascalu et al., 2000; Washing Techniques for Denim Jeans Textile School

Improving water retention capacity of an aeolian sandy soil
Sand-blowing winds at speeds >5 ms −1 occur 220 to 580 times per year, and the height of sand dunes does not exceed 10 m. In addition to aeolian sandy soil, both Jurassic sandstone andSand filtration will be the principle means of treating drinking water for many years. The process has served us well, however with the increasing demands on our water resources and pressure to continue to improve water quality, we have perhaps reached the limit of sand filter performance.

Slow Sand Filtration: Design, Operation, and
cleaning process. Filter bed. Any inert, granular material can be used as the filter medium, but sand is usually selected because it is cheap, durable, and available. When placed in the filter, the sand should be free from clay, soil, and organic matter. Sand used in slow sand filters should be relatively fine, have an effective sizewith different colour shade. The wash fastnesses of dyed cotton treated by soaping with detergents are similar and gradually decrease from grade 5 to grade 4-5 with an increase of colour shade. In contrast to reflux, the wash fastness is slightly worse, which are all at grade 5 due to its outstanding dye elimination property.Improvement of Colour Fastness for Deep Blue Shade of

Denim Stone Washing Process Alternate Methods for Stone Washing
To minimize the drawbacks explained earlier with pumice, stone-washing of denim is carried out with different methods as explained below. 1. Perlite stone wash: Perlite, a naturally-occurring silicon rock has the distinctive property of expanding 4–20 times its initial volume, when heated at a particular temperature.The attractive green color, which resembles the color of fresh-cut moso bamboo, was obtained by treating bamboo with 2% CP solution at 60°C for 3h, using a 1∶1 CrO3/H3PO4 ratio in aqueous solution.Improving the anti-mould property of Moso bamboo surface
