A gray level image segmentation algorithm is proposed based on Average Intensity Project (AIP) and shift Gaussian model for gray level images with connection between thread and area with similar gray level. The evaluation is performed on 30 gray level images, and the results show area overlap measure...

The compatibility, stability and the pyrolysis behavior of aluminum based solid-liquid compound fuel were systematically investigated by thermogravimetric analysis (TGA). The compound fuel lost its 30% weight before the temperature rose to 150 . AP decomposed at 210 and lead to 50% weight loss. The reaction...

Based on a new buffer layer, the characteristics of multiple proton implantations field stop IGBT ( MPI-FS-IGBT) were simulated and analyzed Different from the conventional field stop IGBT (FS-IGBT) which has an abrupt thin buffer layer and grade-doping field stop IGBT(GFS-IGBT) whose buffer layer was...

Coordinated volt/var optimization is fundamental to power dispatch and stability of power system, a novel particle swarm algorithm based multi-agent(MAPSO) is presented. The algorithm combines particle swarm optimization algorithm(PSO) with multi-agent system(MAS). The PSO-MAS utilize an agent as a particle...

The immobilization of lactase is a more attractive approach to overcome the disadvantage of the free lactase. In the presented work magnetic Fe304 fluid was synthesized by chemical coprecipitation and its surface was modified with sodium oleate. Then the liquid paraffin was used as dispersant and glutaraldehyde...

In sewage treatment, the sewage whose carbon and nitrogen(C/N) ratios is less than 8 is defined as low C/N ratio sewage. This study contrasts the treatment effects under different C/N ratios in aerobic membrane bio-reactor. The experiment is performed in the following conditions: Temperature is from...

Ever since practicing the policy of reformation and opening, the economic development of Guangdong province has roughly experienced the three stages: the take-off stage (1979-1991),the accelerating development stage (1992-2002) and the scientific development stage (2003-now). Guangdong Province has made...
