A system and method for reducing switching overhead in a communication network and a web-based server incorporating the system or the method. The timing device in accordance with the embodiments of the invention has a grid array architecture. conventional calcination or semi-graphitization. The second updating controller is configured to, when the graphic pattern is present, update values of the pairs of second coordinates corresponding to the partial stroke to values of the pairs of converted coordinates of the pairs of first coordinates. Otherwise, the single-crystal material can be subjected to annealing or chemical etching so as to form nano-holes along the high-density dislocations to provide a thin film device, such as a molecular sieve film or a carbon-dioxide separating film.
