In this paper, pulverized coal from industry was used as the experimental material and sieved into seven samples with different particle size. The effect of particle size on the flow properties of pulverized coal was investigated. An annular shear cell was used to measure angle of internal friction, angle of effective internal friction, cohesion and angle of wall friction, and a transparent Perspex...
Lifetime network is the main considering problem when deploying wireless sensor networks for integrity monitoring of pipeline infrastructures. And the low network lifetime is always caused by the unbalanced energy consumption in the monitoring networks. So in this paper, a sort of data transmission approach based on probabilistic model is put forward to solve the energy consumption unbalanced and...
