A process is provided for producing wear-resistant boride layers on metal material surfaces. Each of the trenches is filled with a plurality of epitaxial layers of alternating conductivity types constituting nano tubes functioning as conducting channels stacked as layers extending along a sidewall direction with a \u201cGap Filler\u201d layer filling a merging-gap between the nano tubes disposed substantially at a center of each of the trenches. The channel body has a pair of opposed ends. The first and second members are operably connected to each other at the first and second pivot points. The application is started and shut down several times and packets transmitted between a client and server during the running of the application are analyzed to generate application recognition data used for subsequent recognition of the target application by the network.
