An anti-rash diaper for preventing and treating diaper rash and skin irritations comprising: an absorbent layer, where the absorbent layer draws moisture; medicated ointment, where the ointment is applied over the absorbent layer; and a protective sheet, where the protective sheet is releasably attached over the ointment. The substrate includes a display area displaying an image, and a peripheral area surrounding the display area. However, if the queue level crosses beyond a hysteresis threshold, then packets are discarded pursuant to a drop probability. The shield case includes a holder into which the module case is inserted through an opening. These simulations scripts are loaded within a simulation environment within computer systems such as a personal computer.
