This article analyzed the reservoir siltation and the prevention measure, to achieve a new desilting method with the advantages of low energy consumption, high sediment concentration, long-distance transport, and silt discharge and sediment transport through spiral flow can achieve these requirements. According to the experiment we can discover that using the spiral flow to discharge reservoir desilting...
To cope with the deterioration of the atmospheric environment and to examine flue gas desulfurization for recyclable resources, a flue gas desulfurization technology using scrap iron was developed, which achieved better desulfurization performance in a small-scale experimental study. In addition, economically valuable by-products can be produced from the proposed flue gas desulfurization. Based on...
The advantage and weakness of mobile agent migration strategy have an important impact on user's task that the agent completes. The agent flooding mechanism is proposed to collect network status information duly, and a new kind of traveling agent is included into the mobile agent system to improve the real-time performance, and self-adaptation ant colony algorithm is used to search the path, and improves...
The energy consumed by topology maintenance could be higher than that in the initialization stage and the cost will increase steadily with the turns of maintenance process. Therefore, when design a self-organization protocol for WSN, not only initialization cost should be considered but also the maintenance cost in the whole lifetime. Moreover, to reduce the footprint on system resource, the maintenance...
Energy efficiency is a key problem of wireless sensor networks. Though we already have many self-organization protocols which can build energy-saving structures, the energy cost of maintenance also must be concerned. We found that organized network structure has great impact on the energy cost in the maintenance stage and the overall energy efficiency. In this paper, we classify the self-organization...
An important feature of the difference between wireless sensor networks and traditional wireless networks is that energy of sensor node is limited. Therefore, how to design energy efficient sensor network system has been the focus of the study in related fields. Now there are many self-organization protocols in wireless sensor networks, but most only take the initial energy consumption into account...
With the non-hydrostatic mesoscale meteorological model (MM5), the maximum intensity of blood-causing torrential rain occurred in the Leizhou Peninsula from Aug. 8 to 11 in 2007 is simulated. The result shows that the simulated rainfall intensity has a good agreement with the observation, but the simulated appearance of heavy precipitation is slightly later and the rainfall of the precipitation center...
