For the mine of large goaf, there are many factors that affect filling quality. In order to improve quality, it is necessary identify have a significant impact. this paper, fuzzy mathematical method was used analyze five main (PC32.5cement sand ratio, slurry concentration, number lowering, dehydration and drainage, tailing particle size grading) affecting The priority each influence factor calc...

This paper presents a fast end extremely robust feature-based method for planar registration of partly overlapping images that uses a two-stage robust fitting approach comprising a fast estimation of a transformation hypothesis (that we show is highly likely to be correct) followed by a confirmation and refinement stage. The method is particularly suited for automatic stitching of oversize docu...

2.2 Heating and cooling systems The power of the global heating/cooling system has been voluntarily oversize in order to generate an artificial climate whatever the season in the large room. The mains components are: a reversible air-to-water heat pump: 40 kW a second heat pump (only chilled water) : 24 kW an electric coil (24 kW) two regulated fans (supplied & exhausted air) : 0-6000 m3/h a ru...

ASHRAE 55-2004 and ISO 7730 standards failed to predict actual comfort level and lead to oversize design of HVAC system. So proper thermal environment monitoring is an important subject to have right size of HVAC systems. A prototype thermal EM system has been developed. Thermal environment parameters such as: temperature, relative humidity, CO and CO2 are measured by using the developed system...

The montmorillonite sample from Heping, China had been studied by chemical analysis, XRD, IR, AFM and MAS NMR. The results showed that acid concentration had much influence on surface structure of montmorillonite. When the acid concentration reached 2M, the Q3Si structure in silica-oxygen tetrahedron recombined, some Q3Si structure in montmorillonite transformed to distortion Q3Si structure and...
