A method for logging and reporting driver activity and vehicle operation includes identifying a driver of a vehicle, recording operating data with an on-board recorder that is hard-wired to an engine control module, coupled to a mileage sensing system, and linked to a global navigation satellite system, and recording duty status of the driver. To overcome this, a tensile stress is applied to the actuator along an axis substantially perpendicular to the layers of piezoelectric material in the actuator, which tensile stress is sufficient to mechanically align the dipoles, thus giving rise to a remanent strain which is uniform throughout the actuator. The PDF further selects and provides to a policy enforcement function the set of PCC rules for the subscriber corresponding to the first radio spectrum block, for applying to communications with the subscriber during the session. Soybean seed, cells, plants, germplasm, breeding lines, varieties, and plant parts produced by these methods andor derived from soybean variety XB15J13 are further provided.
