A composite stent and methods for making the same are provided. Initially data is received on a frequency channel at a CMTS, specifically an upstream receiver, and by a narrow bandwidth detector, connected to a processor also used by components in the CMTS. The present invention solves this problem by keeping the temperature of the read head at a level that minimizes the noise level. Other preferred aspects of the present invention include methods of cooling the fuel cell by evaporation andor vaporization at the cathode side. Accordingly, a new score for each database image may be collaboratively determined by those ranks, and re-ranking may be performed using the new scores to improve the search results. The pan’s of wires are arranged to create flux lines which will establish alternating magnetic poles separated by null zones in the magnet.
