In wireless ad hoc networks,multiple descriptions (MD) coding of video can effectively improve the quality of transmission,but there is a problem that how to choose the optimal *** order to solve the problem,particle swarm optimization algorithm with adaptive mutation (AMPSO) is presented in this paper,which is used to choose transport path of MD *** method can find the optimal solution quickly and effectively by following excellent particles to search the solution space,and introduce adaptive mutation operator to overcome premature *** results show that AMPSO can effectively guarantee the quality of wireless MD video *** average distortion derived from AMPSO reduces at least 0.04,0.13,0.06,and the speed of convergence is increased by 4 times compared with using GA,SAGA and SPTH algorithm to select routing.

Journal of Wuhan university of technology(Materials science) 2007年第3期22卷 533-536页

The effect of grain size of CaCO3 and SiO2 on the formation of C3S under various conditions, such as rapid heating rate（800 ℃/min）, normal heating rate（30 ℃/min） and in the presence or absence of ZnO, was studied. The results show that the decomposition temperature of CaCO3, the temperature of appearance of liquid phase and the f-CaO content descend when the grain size of CaCO3 and SiO2 becomes smaller, which attributes to the reactive activity enhancement of powders due to the decrease of the particle size. When the grain size of CaCO3 and SiO2 is below 1 μm, the rate of the formation of C3S is greatly raised. A rapid sintering rate and the presence of ZnO have an important effect on the formation of C3S and can lower the temperature of the formation of C3S by about 50 ℃.

作者： Chuanhui LIAO * School of Economics and Management southwest university of science and technology Mianyang China

The author test the relations of carbon disclosure and performance of carbon reduction by regression. Using the data taken from the CDP report 2009, 2010 and Ft500, the results indicate that the relationship between carbon disclosure and the performance of carbon reduction is the significant positive relationship, which means the more the performance of carbon reduction companies, the more disclosure made. The results also found that industries with higher sensitivity to environment do not tend to provide more extensive carbon disclosures;companies with higher market value and asset tend to provide of more carbon disclosure.

Considering the characteristics of time-delay,nonlinear and difficult established precise mathematics model in greenhouse climate,and a control system based on predictive-PID cascade control is *** combines the cascade control structure with predictive control algorithm,the inner loop uses a general proportion adjuster and the outer loop uses a Dynamic Matrix Control （DMC）.The control system not only keeps the strong robustness and fast tracking performance of the predictive control algorithm,but also rejects the interference *** result shows that the control quality and the robustness of the system are superiors to the general PID system.
