A computer-implemented method may include identifying at least one file and detecting an event that is suggestive of at least a portion of the file being duplicated in at least one additional file. The tubular wall is grounded or electrically charged, and an electrically charged conductive core wire is located axially through the center of the stent. The guide member is connected to the body, and it can move relatively to the body. Consequently the critical thickness of strained silicon that can be grown without significant misfit dislocations during later processing is effectively doubled for a given germanium content of the silicon germanium layers. Preferably, the supporting bodies are mounted to be shiftable in the rail-longitudinal direction and to be pivotable about a geometric axis extending in parallel with the displacement direction. The system also monitors abort, fail or cancel conditions in the speech input.
