A method includes determining a rule lookup key for a computer system to be diagnosed, retrieving a diagnostic rule set associated with the rule lookup key, and executing the diagnostic rule set on the computer system. A second porous film having a plurality of second holes is disposed on a first porous film having a plurality of first holes. Drying takes place within this passage duct which includes at least one straight section. The under garments are finished in ribbing located at their terminal ends. The decoder also includes a stored DCT decoder module, which has an input coupled to the memory, a first output coupled to the motion compensation module and a second output that functions as an output of the decoder. The technique has low computational complexity and low storage requirements for the estimator.
