In a method for remote monitoring of alarms, a user interface is provided to a user of a mobile computing. The monitoring system is arranged to shut off the fuel dispensing means in case of detection of a malfunction in the vapor recovery system. The horizontal functional section includes element heads which are meshed with and unmeshed from each other, and horizontal fastener tapes. The superlattice may further include at least one pair of oppositely-doped regions therein defining at least one semiconductor junction. The physical layout estimator is utilized to dynamically produce the physical layout wire-load model and to calculate net length and delay for each optimization iteration.
