One embodiment of the present invention provides a system that uses observed object patterns to dynamically tune a virtual machine for responsiveness andor throughput. The method includes performing a specified number of mass serializations to generate a corresponding number of mass serialization sets. 1 Known pump drives, to the extent that they can be separated from their pumping mechanism, must be set onto the pumping mechanism with two hands, because of their weight. If desired, a filler strip can be inserted between the side wings. The layers include at least an inner layer, an outer layer and a fuel permeation barrier layer disposed between the inner layer and the outer layer and being made of a liquid crystalline polymer material.
