The average daily commute is 52 minutes, noted Google -- time that could be spend doing other things once operating avehicle is taken out of the equation.
Under a general assumption, we establish directly the optimality equation for infinite time horizon average cost model and prove the existence of optimal solution in a compact action set by using p.
The substructure method was introduced to set up mathematical model of finite periodic composite structure, to solve its wave equation, and to derive its time-average power flows.
