We consider different models of stochastic dissipative equations and theoretically compute the probability distribution functions (actually the associated large deviation functions) of the time averaged injected power required to sustain a nontrivial stationary state. We discuss the results and...

Random walk on percolation under an external field has been investigated by using statistical analysis and Monte Carlo simulation. The mean square displacement 〈R2〉 as a function of time t was obtained. There exist some steps in the log〈R2〉–logt plot. The defect in the percolation...
