With internationally latest studies, the paper also proposes some biquadrate filters which are capable to perform the functions of second-order low pass、 high pass、 band pass、 band stop、 all pass filtering by selecting one of the three inputs or their proper combinations from the same configuration, furthermore whose natural frequency and the quality factor can be tuned independently. Then a continuous-time biquadratic filter using CCCII is proposed, which can be used in hearing aids and in other analog signal processing applications. Lastly a current mode and a voltage mode novel n-order filters of multifunction are presented. Not all both of the n-order filters are electronic tunable,but also they are integrated conveniently and compatible with VLSI technology.

This study uses the soil parameter reduction coefficients to model the seismic pile responses affected by liquefied soils. One dimensional wave equation analyses were conducted for the solutions. Based on the bore-hole data and nearby seismic record, the soil parameter reduction coefficients of liquefied layers can be obtained through a pre-analysis for liquefaction potential of the site. The reduction coefficients were used to reduce the soil modulus for liquefied soils, and the lumped mass analysis is performed to obtain the free-field response of the site. The ground deformations are superimposed onto the pile elements for discrete wave equation analysis, and the non-linear pile responses can be simulated through the modified Bouc-Wen model. Thus the deformations and failure mechanism of the pile are able to investigate.
