An apparatus, program product and method utilize a query optimizer that relies upon a plurality of dynamically-dispatchable active strategy entities to generate an optimized execution plan for a database query. An activation determination means 4 activates a charging control circuit 3 by allowing a maximum output current from a solar cell 1 to a GND potential to flow and detecting that the output current is equal to or greater than current consumption of the charging control circuit 3 instead of monitoring an unstable output voltage from the solar cell 1. The linear program solver takes as input a set of creatives, creative performance data, constraints, and slot identifiers. An Erbium doped fiber amplifier has an input connected to the first output of the optical directional coupler and an output. The exposed outer aluminum oxide layer minimizes defects and particles generated as a result of differential thermal stresses experienced by the aluminum component and outer aluminum oxide layer during plasma processing compared to an identically shaped component having a Type III anodized surface.
