The effect of decreases in food energy intake on the activity pattern of an individual may be described by an M^x/M/1 queueing model. \lambda represents the rate of activity arrival to the system. E(k) represents the average energy level at which the system performs, \mu represents the rate at...

Officers in police patrol cars operate in a complex stochastic environment. In addition to handling dispatcher-assigned calls for service from the public, they patrol to pose a threat of apprehension to would-be offenders and undertake certain on-site interventions to help improve general public...
