The present invention relates to computer implemented methods and system for creating and executing an query plan for SPARQL Protocol And Query Language queries. The BACS may include a first switch in signal communication with a high voltage reference and a first current source in signal communication with the first switch. The transistor is biased to provide a well bias voltage, or backgate voltage VBG, which is coupled to transistors provided on a common integrated circuit. After receiving a second move instruction from the host to move a second tape cartridge from the shelf to a second tape drive, the library reorganizes and physically carries out the move instructions with potentially different hardware in a preferred order. If the client identifying information is authenticated successfully against the stored authentication information, the network device is dynamically re-configured to allow network traffic initiated by the client to reach the network resource.
