A network operating center for a network comprising known-location and unknown-location nodes can be configured to receive from each unknown-location node estimates of the distances from that node to each of its neighbor nodes. The clip edge of the clip piece is lowered beyond the clip plane of the retaining piece, preferably into a clip slot configured in the retaining piece or a retaining piece groove such that the documents remain securely clamped even after reducing the stack height. The system and method removes the dependency upon the incorporation of metal catalyst for the production of silicon and germanium nanowire, thereby nullifying the adverse effects of metal contamination in the resulting semiconductor nanowires. The processor then displays tomographic slices of the three dimensional model. During system initialization, a copy of the sequential write buffer and its associated checkpoint index are retrieved and used as a starting location for transferring write data from the sequential write buffer to the magnetic disk storage devices in the RAID array.
