Population density affects the daily contact rate of agents and therefore the number of secondary cases developed per index case, and by setting population and therefore population density as a constant, the model removed a dynamic part of the epidemiological progression [33], [34].
It is also decreasing in r, μ, and δ, the discount rate, and the Poisson rates of agents leaving the labor market and job destruction, respectively.
Longer time of contrast agent inflow indicates the presence of stenosis, and the rate of contrast agent inflow has been shown to be positively correlated with severity of arterial stenosis on cross-sectional imaging [ 49].
The rate of extraction agent loss showed the trend of increase, with the increasing of flow ratio of solvent agent to feed.
Consequently, the loss rate of solvent agent significantly increased.
Therefore, the smaller the total flow rate, the better the separation efficiency, the lower the loss rate of extraction agent.
The rate of solvent agent loss showed a rising trend with the increasing of total flow rate.
However, the rate of extraction agent loss increased from 0.26% to 0.42% with increasing of extraction degree.
α is the learning rate of the agent and determines the importance of the newly acquired reward.
