Methods are provided for producing lubricant base oils from petrolatum. Using computer graphics in a video game, or the like, it is possible to achieve a more realistic object representation, wherein joint regions move in a natural manner. Each of a plurality of received network entry signals is received from the mobile station over a preferred uplink beam corresponding to the received network entry signal. A calibration value representing the down-track spacing is generated based on the TS1 and the TS2. A method implementation of that technique includes the steps of calculating at least one of a detection probability and a false alarm rate for a radio signal usable for the measurement, and obtaining at least one RF performance metric estimate for the receiver based on at least one of the calculated detection probability and the calculated false alarm rate. The battery system is configured to store electrical energy generated by the redundant renewable energy source generator.
