Published: March 2014

Internet has become as a social infrastructure. The current Internet architecture based on TCP/IP is faced with many challenges. This fact makes the clean slate design of future Internet architecture represented by ICN (Information-Centric Networking) be a hot research topic. In this paper, a novel routing scheme for ICN (Information-Centric Networking) is proposed. On the basis of name-based routing, a process was designed to look for other available interface through which the backtracking-condition-met interest packet will be forwarded, which can reduce the network blocking rate. Moreover, FIB (Forwarding Information Base) of neighbor nodes will be modified when data packets go through a router, which can realize the efficient use of cache. Also, a concept of "popularity" is introduced to improve CS (Content Store) hit rate. The proposed routing scheme is implemented on NSFNET by simulation, and the experimental results have shown that it is feasible and effective.

Authors: Xing En Jun , Zhao Fu Qiang , Zhang Shuo , Ge Xin Yu
Published: March 2014

In connected graph, edge centrality represents the importance of edge and loading degree in the process of information transmission. The second eigenvalue of Laplacian matrix decides connectivity of complex networks. We propose edge centrality model and cut model based on minimization model of the algebraic connectivity. Edge centrality function is derived in order to calculate edge centrality. Cut model deletes k edges at an iteration whose algebraic connectivity of complex networks decreased fastest. Choice of k is based on edge sparse degree of complex networks. By empirical analysis of real network, the implications of edge with higher centrality and its vertex coincide with the fact. The model can be used in medium-size networks with lower time complexity and higher efficiency.

Published: March 2014

Semiconductor manufacturing is a capital-intensive and high-tech industry. In order to reduce production cycle time and increase production flexibility, the semiconductor manufacturers will expand the capacity in the existed fab and build up new fabs. However, the expandability of production capacity is not infinite since the huge fab scale will increase risk of production management. Therefore, it is necessary to find out the factors which will influence the performance of fab scale. This research uses the eM-plant simulation software to construct a simulation environment to conduct simulation experiment. The experimental environments were divided into two parts and named as high and low product mix complexity separately. Furthermore, three more factors were taken into accounts, which included stability of machine, variation of fab scale and releasing rate. By simulation, the analytical data is collected and analyzed its trend in these different environments. Simulation results reveal the significance of factors under different environments. Based on these results, the managers can conclude an appropriate fab scale in giga-fab, which will help to reduce the cycle time of products and increase the total throughput of giga-fab.

Applied this method onto high-tech word similarity measurement, and acquires high-tech word similarity matrixes. Cluster based on this high-tech word similarity matrix. Construct high-tech ontology, according to cluster result. Extract the corresponding high-tech monitoring indicators and values of high-tech ontology through Regex. Finally construct high-tech transfer monitoring ontology, and monitor the sustainable development of high-tech transfer. Formulating high-tech word similarity computing software achieves high-tech word similarity computer measurement and verifies the feasibility and accuracy of this computing model.

In this paper, we try to find out the synergistic effect between energy industry investment and economic development. Based on the objective, with computer aided method, we choose the statistic data of energy industry investment and GDP of China from 2001 to 2011, use econometrics software Eviews 5.0 and least square method to build the linear regression model between energy industry investment and GDP. The result shows that there exists a linear correlation between energy industry investment and GDP; moreover, energy industry investment is more influential than the GDP.

The precise analysis the details of the action and trajectory in the hurdlers technical videos can provide training deficiencies for the coaches.To realize the analysis of technical videos, we must firstly detect and track the athletes in the video. Based on the Opencv vision library of Microsoft Visual Studio 2008, we solve the problem of background shake by Surendra algorithm. Then the probability distribution of the target pixel to positioning the athletes is calculated using Kalman filter algorithm to predict its trajectory. Finally, we finish the recognition and detection of athletes by a combination of both methods.

Retired Athletes reemployment problem is a long-term big problem. Combined with the characteristics of Chinese sports system, the retired athletes retired various emotional and behavioral reactions of transition during the intervention support, help the athletes to role positioning, the establishment of a new way of life, to develop good habits, to establish and the social network to adapt to the new. All of these aspects of psychological support can be transformed into transition resources, forming applied to retire the ready state, and dynamically active influence retirement transition stage.

Published: March 2014

Halbach magnet array has advantages of its small size and yokeless, so it has been widely used in various areas. In this paper, two Halbach permanent magnet arrays for small-size NMR with cube and octagonal shape, respectively, were compared in parameters of average magnetic field strength, field homogeneity and volume with the same material consumption. It was found that the octagonal shape magnet has better performance than the cube one. Then the field homogeneity optimization for octagonal magnet was performed. By analysis of magnetic field strength, the best homogeneity in 5mm DSV (Diameter of Spherical Volume) with 133.4ppm was achieved when the height of magnetic blocks is 16.25mm. After optimization, the magnetic field homogeneity has been significantly improved when the shape of magnet has small volume. This result laid a foundation for the design and manufacture of the octagonal Halbach permanent magnet array in small size.

Published: March 2014

A novel design of flat chip-size microchannel heat sink for high power devices cooling is proposed and optimized. The inlet of cooling media is placed in the highest heat flux region, leading the coolest media into the region with the highest temperature directly, and as a result, the overall cooling efficiency is improved. Simultaneously, the collect channel is set and the inlet position is slightly off-center, which achieves a uniform temperature distribution. With the aid of a computational fluid dynamics (CFD) method, the temperature distribution of microchannel heat sink under steady-state conditions is examined and the microchannel distribution is optimized, forming an optimal design for the chip-size microchannel heat sink.

The problem of power system reactive power optimization is a mathematical problem with multiple variables and constraints, which is complex and non-linear. The control variables include continuous variables and discrete variables; its difficult to get the optimal solution. A solution in power flow calculation is put forward after the mathematical model of wind farm is built in this paper. Based on this, taking the WSCC 9 nodes system as an example, use the particle swarm algorithm to solve the reactive power optimization problem.
