A radio frequency transponder for use with a disc, such as a CD or DVD has an antenna formed by depositing a conductive solution on a surface of disc outside at adjacent to its outer periphery outside of the disc storage area to yield at least one conductive region. A determination is made that a client is initiating a communication session. The amount of the coating on the paper web is determined on the basis of the amount of at least one component in the coating on the paper web and the composition of the coating to be transferred to the paper web. A silane compound in the first conductive polymer layer and the silane compound in the second conductive polymer layer have respective concentrations different from each other. The block is securely retained within the recess. The subset of the set of the congesting vehicles is rerouted to a candidate route section identified in the vacancy data structure.
