In order to classify packet, we propose a novel IP classification based the non-collision hash and jumping table trie-tree (NHJTTT) algorithm, which is based on noncollision hash Trie-tree and Lakshman and Stiliadis proposing a 2.dimensional classification algorithm (LS algorithm). The core of algorithm consists of two parts: structure the non-collision hash function, which is constructed mainly based on destination/source port and protocol type field so that the hash function can avoid space explosion problem; introduce jumping table Trie-tree based LS algorithm in order to reduce time complexity. The test results show that the classification rate of NHJTTT algorithm is up to 1.million packets per second and the maximum memory consumed is 9 MB for 1. 000 rules.

This paper describes a case study of 3D protein structure prediction of six sequences from protein data bank （PDB） by genetic algorithm and tabu search （GATS）, where off-lattice AB model is considered as a simplified model of protein structure. The lowest-energy values required for forming the native conformation of proteins are searched by GATS, and then the coarse structures （i.e., simplified structure） of the proteins are obtained according to the multiple angle parameters corresponding to the lowest energies. All the coarse structures form single hydrophobic cores surrounded by hydrophilic residues, which stay on the right side of the actual characteristic of protein structure. It demonstrates that this approach can predict the 3D protein structure effectively.

The elastic moduli of short-fiber-reinforced foams depend critically on the fiber content and fiber length, as well as on the fiber orientation distribution. Based on periodic tetrakaidecahedrons, the finite element models with short-fiber reinforcement were proposed in this paper to examine the effects of the fiber content and fiber length on Young's modulus. The fiber length distribution and fiber orientation distribution were also considered. The proposed models featured in a three-dimensional diorama with random short-fiber distribution within or on the surfaces of the walls and edges of the closed-cells of polypropylene (PP) foams. The fiber length/orientation distributions were modeled by Gaussian prob-ability density functions. Different fiber volume fractions, different lengths, and different distributions were investigated. The predicted Young's moduli of the PP foams with short-glass-fiber or short-carbon-fiber reinforcement were compared with other theoretic and experimental results, and the agreement was found to be satisfactory. The proposed finite element models were proved to be acceptable to predict the Young's moduli of the grafted closed-cell PP foams with short-fiber reinforcement.

Superconductivity of small metal grains

The formulas of the energy gap and superconducting critical temperature appropriate for systems with both odd and even number of electrons are derived; the bases of the derivations are BCS theory and energy level statistics. Numerical results qualitatively agree with the experimental phenomena. i.e., the superconductivity of small metallic grains will first enhance then decrease to zero when the grain are getting smaller and smaller. The calculations indicate that the above phenomena happen in the metallic grains belonging to Gaussian Orthogonal Ensemble (GOE) and Gaussian Unitary ensemble (GUE) with zero spin; The superconductivity of small metallic grains in Gaussian Symplectic Ensemble (GSE) will monotonically decrease to zero with the decreasing of the grain size. The analyses suggest that the superconductivity enhancements come from pairing and the balance of the strengths between spin-orbital coupling and external magnetic field. In order to take the latter into account, it is necessary to include the level statistics given by Random Matrix Theory (RMT) in describing small metallic grains.

During the popular and development in Internet, mor e and more EC systems are running on Internet. Manufacture enterprise establishes EC system, integrates the systems between enterprises replace the traditional MI S system. The manufacture enterprise will face some difficulties when it begins to establish EC system. In order to solve the difficulties, the EC system not on ly includes the functions which in general EC system, but also integrates ERP sy stem, manages the enterprise from three aspects: relationship between manufactur er and customers, enterprise resources, and supplying chain, and gives the manuf acturer more intelligent information. As the departments of enterprise exchange data very frequently, connect the sellers and suppliers by using Internet, the t raditional C/S architecture isn’t satisfied by present needs. It is the only wa y that uses Multi-tier architecture. EJB (Enterprise Java Bean) is a Multi-tier distributed architecture designed by SUN company. The Enterprise JavaBeans architecture is a component architecture for the development and development of component-based distributed business app lications. Applications written using the Enterprise JavaBeans architecture are scalable, transactional, and multi-user secure. These applications may be writt en once, and then deployed on any server platform that supports the Enterprise J avaBeans specification. There are many superiorities using EJB when design compu ter system. The EC System for Manufacture Enterprise is based on EJB architecture. We define four EJB containers, namely, CRM component, POM component, Knowledge Management component and ERP component. CRM EJBs take the form of managing the customer- supplier relationship, reducing the number of contracts the manufacturer must ma ke with the end customers. POM EJBs take the form of order processing activities . These order taking, order fulfillment, and managing the logistics and transpor tation involved in the physical movement of the

Rare Metals 2007年第3期26卷 247-253页

Highly conductive and transparent Al-doped ZnO （AZO） thin films were prepared from a zinc target containing Al （1.5 wt.%） by direct current （DC） and radio frequency （RF） reactive magnetron sputtering. The structural, optical, and electrical properties of AZO films as-deposited and submitted to annealing treatment （at 300 and 400℃, respectively） were characterized using various techniques. The experimental results show that the properties of AZO thin films can be further improved by annealing treatment. The crystallinity of ZnO films improves after annealing treatment. The transmittances of the AZO thin films prepared by DC and RF reactive magnetron sputtering are up to 80% and 85% in the visible region, respectively. The electrical resistivity of AZO thin films prepared by DC reactive magnetron sputtering can be as low as 8.06 x 1.-4 Ωcm after annealing treatment. It was also found that AZO thin films prepared by RF reactive magnetron sputtering have better structural and optical properties than that prepared by DC reactive magnetron sputtering.

Given the hyperbolic measure dxdy/y2.on the upper half plane H, the rational actions of PSL2.R) on H induces a continuous unitary representation α of this group on the Hilbert space L2.H, dxdy/y2.. Supposing that A = {Mf : f ∈ L∞(H, dxdy/y2.}, we show that the crossed product R(A,α) is of type I. In fact, the crossed product R(A,α) is *-isomorphic to the von Neumann algebra B(L2.P,ν))■LK, where LK is the abelian group von Neumann algebra generated by the left regular representation of K.
