Each image print apparatus is connected to a nearest base station by radio, and a plurality of base stations are connected to a public communication network. The device is equipped with a Bluetooth radio configured to interface with an audio device such as a cell phone or Mp3 player over conventional Bluetooth wireless frequencies. The rehistogram provides an individual frequency relative to the total frequency of the recurrent behavior. Each of the bumps in the first plurality of conductive bumps is larger than each of the bumps in the second plurality of conductive bumps. The cable assembly attaches the bar of a free-weight assembly to the weight responsive engagement assembly by means of a cable attachment assembly 1211 and sheaves 1213A, 1213B. One or more disruptions are introduced into a pre-selected airline flight schedule, using frequency distributions of disruptions and disruption severities, resulting in a disrupted flight schedule that reflects both initial and propagated delays.
