Computer simulation of the paths \(\pmb{S(t)}\) , \(\pmb{x_{1}(t)}\) , \(\pmb{x_{2}(t)}\) , \(\pmb{c(t)}\) of the stochastic chemostat model ( 2 ) for impulsive effects. (a) Time series for \(S(t)\), \(X_{1}(t)\), \(X_{2}(t)\), \(c(t)\) with parameters \(\sigma_{1}=0.1\), \(\sigma_{2}=0.1\), \(u=2\). (b) Time series for \(S(t)\), \(X_{1}(t)\), \(X_{2}(t)\), \(c(t)\) with parameters \(\sigma_{1}=0.1\), \(\sigma_{2}=0.1\), \(u=0\). (c) Time series for \(S(t)\), \(X_{1}(t)\), \(X_{2}(t)\), \(c(t)\) with parameters \(\sigma_{1}=0.1\), \(\sigma_{2}=0.1\), \(u=0.2\).
