Black et al. [1] learn a subspace model offline to represent target objects at predefined views and build on the optical flow framework for tracking.
In [2], Black et al. extend their subspace representation method to a mixture model which can better account for change of object appearance.
Instead of describing objects with a blob of pixels, David et al. [4] learn an adaptive linear subspace online for modeling target appearance and implement tracking with a particle filter.
Collins et al. [9] use variance ratio of foreground and background classes to determine discriminative features for object tracking.

Seismic behavior of steel frame structures with viscous damper was studied by Chang.et.al., [3].
Hahn et al.,[4] developed a parametric analysis to determine the optimum damping coefficient.
Zhang et al.,[5] and Wu et al.,[6] proposed another method for optimum damper positions in buildings with specified storey stiffness.
Pong et al.,[7] introduced a finite element model for fluid dampers in study.
This type of analysis is used to determine the response of structure under the action of El-Centro earthquake data.

The 10Al2O3-5B2O3-85SiO2-0.6Eu2O3 glass was prepared by the sol-gel
process using tetraethylorthosilicate (TEOS), Al(OC4H9sec)3, (B(OC4H9)3, EuCl3·6H2O, ethanol, and
deionized water as the starting materials.
Macfarlane et al. studied PSHB of silicate glasses containing Eu 3+ ions.
Fujita et al. proposed the photo-induced electric charge redistribution between Eu 3+ and Eu 2+ ions as a mechanism for PSHB in some glasses [18,19].

Askari-paykani et al. [8] investigated the microstructural changes and stress corrosion cracking behavior via two-stage stressing u-bent tests for T6 and T73 tempers of Al 7075 Alclad alloy.
Amjad Saleh El-Amoush [11] investigated the effect of annealing conditions producing various grain sizes on the intergranular corrosion behavior of high-strength aluminum alloy 7075-T6 using electrochemical polarization techniques.
Li et al. [12] studied the influence of two novel aging treatments, T6I6 (130℃/80min+65℃/240h+130℃/18h) and high-temperature pre-precipitation aging (445℃/30 min+120℃/24 h) on the tensile properties, intergranular corrosion, exfoliation corrosion behaviors and microstructures of 7075 Al alloy, and compared them with the T6, T73 and RRA treatments.
Wand et al. [13] discussed the effect of pre-strain and two-step ageing on microstructure and stress corrosion cracking of 7050 alloy.

Experimental
Preparation of base catalysts
Commerical NaY, Si/Al=2.8 from Zeolyst (Nankai University) were used as starting materials.
Acid HY zeolite(Si/Al=2.8) was prepared from NaY zeolite by NH4+ exchange followed by deep calcination at 550 .
CNH analysis (Model Elementar Vario EL III) was performed at a temperature of 1000 ℃.
They were respectively assigned to vibrations of SiOH groups and Si-OH-Al or EXFAI species.
(Eqs.(4)) ≡Si-OH-Al≡+ NH3→≡Si-NHx-Al≡+H2O (x=1 or 2) (3) ≡Si-O-Si≡+ NH3→≡Si-NH-Si≡+ H2O (4) Pyrrole adsorption Pyrrole was used to characterize zeolite basicity and was the most studied amongst the proposed acidic probe molecules.
