Thirdly, a new type base isolation system, i. e., slide-limited friction base isolation system is presented in this paper. Based on this system, harmonic and subharmonic periodic response of S-LF subjected to harmonic motion is investigated by using Floquet theory. Dynamic response of sliding structure subjected to earthquake ground motion is calculated with a precise high order direct integration method, and the numerical results are presented in terms of maximum acceleration response spectra of supcrstructure and maximum sliding displacement response spectrum. By comparison with isolating effects of pure-friction base isolation system and resilient-friction base isolation system , it shows that the isolating characteristic of S-LF is superior to P-F and R-FBI. Through analyzing an engineering example, it is observed that the maximum inter-storey shear force and absolute acceleration of sliding structure to earthquake ground motion are very different from those of traditional structures.

This scheme was composed of two parts: intra prediction and inter prediction. For the intra prediction part, 8×8 block DCT-HT transform-domain converse was used, and then intra mode decision was done in HT domain to obtain the optimum mode, so that good intra prediction was acquired. For the inter prediction part, Motion Vector got from Variable Length Decoding in MPEG-2 stream was reused as Prediction Motion Vector of H.264, then motion prediction mode and search region were reset, so that better prediction result was acquired.
