A method for producing a measurement structure for measuring alignment of patterns formed in one or more layers of patternable material uses multiple exposure tools having different resolution limits and maximum expose field sizes. The processor under the control of a program generates a deceleration velocity profile for the seek operation that is determined based upon a deceleration velocity profile function that includes a back electromagnetic force model to take into account back electromagnetic forces associated with the coil of the actuator such that the BEMFs are mathematically modeled. The rating of the recommended-for-purchase media item as being similar to the designated media item presently contained in the inventory of the media library of the program participant is representative of a frequency at which the recommended-for-purchase media item co-occurs with the designated media item in media libraries of others. For example, determining may involve utilizing a movement sensor to detect the movement of the ME, andor receiving signals from a Global Positioning System or the like. Inbred maize lines derived from inbred maize line PHADP, methods for producing other inbred maize lines derived from inbred maize line PHADP and the inbred maize lines and their parts derived by the use of those methods. If the first server fails to indicate it has completed and stored the voice message in a timely manner, the second server stores the recorded voice message.
