The present invention provides methods and systems for use in bid optimization in connection with advertisement serving impression opportunities available in an auction-based online advertising exchange. The information for determining the nozzle position makes determination in accordance with image data of an ink with resin and image data of an ink without resin. Post-processing heuristics for fair sharing can be applied to the first round solve of the main LP. First and second spaced apart seals are positioned along the shaft. The present invention includes calculating, on a processor at a user equipment, a transmission power based on currently used bandwidth, and checking, on the processor at the user equipment, whether a transmission power limit has been reached based on the calculated transmission power.
