The main factors affecting the soil-structure interface behaviors were found experimentally and theoretically, including: 1 the thickness of the interface that is five to six times the average grain size of the soil; 2 the aeolotropy of interface, which is responsible for anisotropic response of the stress-strain response of the interface; 3 two physical states, including crashing and compression of the soil near the structure surface, which govern the stress-strain response of the interface strongly; 4 two shear deformation components due to sliding and constraint of the structure surface relative to the soil respectively, which forms the deformation of the interface; 5 the volumetric strain due to dilatancy, which is found to be composed of a reversible dilatancy component and an irreversible dilatancy component. 4. A unified constitutive model of the interface, based on new elasto-plasticity damage theory, was developed. It was confirmed to be effective for the conditions considering monotonic and cyclic shearing, coupling effect of shear and volumetric strains, evolution of physical state, micro-structure aeolotropy of the soil and the resulting aeolotropy of the interface as well as the three normal boundary conditions stated above. 5. 2D and 3D finite element formulations of the present model were derived and incorporated into the FEM codes. They were applied to the evaluation of practical engineering problems with different typical interfaces between soil and structure. The new model was shown to be reasonable and effective.

We indicate that when wavelength number is larger than 16, even 8, all of the networks show good small blocking performance. Further, we discuss different aspects that affecting blocking, including routing, wavelength number, wavelength assignment, wavelength conversion, multi-fiber and network connectivity. We find out that increasing wavelength or implementing multi-fiber can reduce blocking dramatically while in light loads (<0.4Er), fixed alternate routing or First Fit wavelength assignment can improve the performance to some extent.
为了进一步获得更优的阻塞特性,研究比较了影响阻塞率的几个重要方面,包括路由(固定路由与固定可选路由)、波长数与波长分配算法、波长变换与多光纤、网络连接度,结果表明阻塞特性通过增加波长或采用多光纤可以得到明显的改善,在负载较轻时(<0.4Er),改用可选路由方式或First Fit波长分配算法也可以一定程度地改善阻塞率,但是这种改善受网络连接度和波长数的影响比较明显。

For gas flow past cylinder, the characters of flow field in different Mach number and Knudsen number condition were investigated, and especially for low Knudsen number cases, the results were compared with calculating results of Euler's equation. It showed that they are correspondent by comparing the characters of bow shock and wake. The convergence rates of different high resolution and implicit schemes were also investigated. The convergence behavior of the implicit WENO scheme developed in this paper is better than others. For gas flow past NACA 0012 airfoil, the calculating results were compared with results of experiment. It showed that the results of WENO scheme are of higher accuracy for the case with angle of attack.

At the bookish assembly hosted by Secretary General Huang Chin-ying on January 3, Mr. Chang Pei-chen presented the first report on the Secrets of the 17-year Cicada written by Japanese Jin Yoshimura, a specialist of eco-mathematical model and biological evolution. The book was adapted from Yoshimura』s paper published in American Scientist in 1996, exploring the causes of evolution of magicicadas. Based on the duration of dormancy, magicicadas fall into two groups: the 13-year and 17-year periodical cicadas. Based on the principle of the survival of the fittest, as the lowest common multiple was larger, there were fewer groups proliferating at the same time to prevent damage of their ecological regularity as a result of hybridization.
