In order to improve the network coverage, this paper presents the research on wireless sensor network coverage based on improved particle swarm optimization algorithmfor wireless sensor nodes that are randomly deployed in a certain area. In this paper, we use the regional network coverage as the target objective function, and combine various improved particle swarm optimization algorithms to optimize...
This paper will determine the canopy spectral reflectance and disease severity of processing lomato bacterial spot disease in field and disease nursery. The canopy spectral reflectance In different varieties and different growth stages are transformed into first-order differential, second-order differential, and inverse logarithm spectral reflectance. We analyze the correlation of the disease severity...
Alkali emitted from chemical industry not only results in environmental damage, but also serious resource waste. As the emitted alkali lye is complied with the principle of Turin (the solution's boiling point is complied with the linear relationship with the water's at the same pressure) and its boiling point rising is not big, a set of new high efficiency heat pump evaporation alkali recovery system...
