A system and method of measuring displacement of energized components within a tap changer compartment. The strategy is embodied in an algorithm employing variables including start of supplemental gasoline fueling, end of supplemental gasoline fueling, ramp-in period of supplemental gasoline fueling, ramp-out period of supplemental gasoline fueling, and the fraction of supplemental gasoline fuel to be delivered relative to that which is normally delivered during a conventional gasoline start. In accordance with the technique, a viral diffusion curve associated with a therapy of interest is generated and each dot spectrogram is then mapped to the viral diffusion curve using fractal filtering to yield a filtered viral diffusion curve for each sample. The front and back electrode layers of the lighting units serve to control the lighting layers of the lighting units to emit light. In another embodiment, the invention discloses pharmaceutical compositions comprising such compounds as well as methods of using them to treat disorders associated with the HCV protease. and at a pressure of between 100\xd7105 Pa and 160\xd7105 Pa, wherein the level of supercritical CO2 is between 30 and 70, and recovery of the residue comprising at least 50% of DHA relative to the total fatty acids of the residue or to derivatives thereof, wherein the DHA yield is greater than or equal to 60%.
