A system stores a snapshot and an associated data structure or index to storage media to create a secondary copy of a volume of data. The at least one aperiodic RI may correspond to at least one component carrier wave in each of the serving BS and an adjacent BS for CoMP transmission of the serving BS and the adjacent BS, and the at least one periodic RI may correspond to at least one component carrier wave for non-CoMP transmission in the serving BS. These deflectors each have a deflection surface to deflect downward the airstream flowing over the upper surface of the wing to act as a \u201cbrake\u201d to the forward motion of the aircraft and to provide additional lift so that the aircraft may hover. For example, a particular space-time coding matrix may be selected from a number of generated space-time coding matrices based on a number of non-zero off-diagonal elements or a power of a trace of the associated correlation matrices. The disclosure also includes an implementation and operation for a contextual pattern decoder engine configured to extract knowledge attributes and contextual taxonomy from classified blocks of an input data stream.
