The present invention generally comprises a method and apparatus for bonding a cylindrical sputtering target to a backing tube. The bone screw may comprise a head at a proximal end and a bone connection element at a distal end. To that end, the caching filer further includes a multi-protocol engine configured to translate the multi-protocol client data access requests into generic file system primitive operations executable by both the caching filer and the origin server. A ratio of two predictive intensity functions is formulated, and the ratio is iterated to determine the thickness of a layer of the structure. The generation module generates a processed bitstream comprising markers and NAL units. Consistency between the first control information as detected, and the second control information as detected is determined and on the basis of results of the determination, the control of the contents is executed.
