When the path planning is carried out for the traditional ant colony algorithm, the convergence speed is slow and it is easy to fall into the “self-locking”, and it is not easy to find the optimal path. A fusion ant colony-A* algorithm is proposed to solve the problem. The evaluation function of A* algorithm is introduced to improve and adjust the heuristic function and pheromone update mode of traditional ant colony algorithm, and reduce the possibility of “self-locking”, so that the optimal path can be quickly found. Finally, experiments are carried out on MATLAB simulation software. The experimental results show that the proposed algorithm improves the convergence speed by nearly 40%, and the optimal paths in environmental models 1 and 2 are 35.670 6 m and 29.799 0 m better than the 39.799 0 m and 32.213 2 m of the ant colony algorithm.

Two geometrically identical half-scale RC shear wall-frame structure specimens were constructed and tested under quasistatic reversed cyclic lateral loading to study the seismic behaviors of the RC shear-wall frame structure, such as its failure mechanism, failure mode, plastic hinge development, hysteretic response, displacement ductility, stiffness degradation and energy dissipation capacities. One unit was a conventionally cast-in-situ concrete shear wall-frame structure specimen named RCFW, and the other unit was a precast one named PCFW2 erected with fabricated shear walls and frame components. The test results show that specimen PCFW2 has approximately equal cracking load, similar failure process and final failure mode to specimen RCFW. Two kinds of rebar connecting methods, rebar splicing by grout sleeve and rebar lapping in grout-filled hole, can transfer the rebar stress effectively. Specimen PCFW2 shows good integrity. The seismic characteristic values such as yield load, peak load, and ultimate load of specimen PCFW2 are less than those of RCFW, where the difference is approximately 13.0%. The displacement ductility coefficient of specimen PCFW2 is also less than that of RCFW. The test results also show that the energy dissipation capacity of PCFW2 is greater than that of RCFW at the most loading stage during the whole loading process. The edge columns of the shear walls in the wholly precast RC frame-shear wall structure is proposed to be connected with rebar splicing by grout sleeves, and the rest part of the shear walls with rebar lapping in grout-filled holes. Micro-expansive concrete is proposed to be used in the wet joints of the frame parts as cast-in-place concrete. [ABSTRACT FROM AUTHOR]

Superpixels algorithms have been applied to various fields of computer vision in recent years. Superpixels can capture the redundant information of the image and reduce the complexity of post-processing. As the preprocessing o£ images，superpixels segmentation needs to meet the demands of real-time properties and accuracy o£ image processing. We propose an improved fast SLIC segmentation algorithm in the framework of the SLIC algorithm to improve the efficiency of superpixels segmentation. We extract a small number of pixels o£ the original image to generate a small scale image by reducing the scale of the original image，and employ the SLIC algorithm to do superpixels segmentation of the downscaled image. After the primary superpixel segmentation，we perform K nearest neighbor classification on the pixels of the original image according to the segmentation results of the downscaled image and realize final superpixels segmentation. Experimental results show that with similar accuracy，the proposed algorithm is much faster than the SLIC algorithm when processing the same object. [ABSTRACT FROM AUTHOR]

Based on the situation in which the requests could not be predicted in advance and the service time of each request is uncertain, this paper proposes the online traveling salesman problem with service time. A lower bound and PAH-ST algorithm are presented for general metric space. Moreover, a lower bound and PQR-ST algorithm are presented for real line. Competitive analyses are given to the two algorithms respectively. The model proposed in this paper is the general form of the traveling salesman problem. The conclusion can provide the basis of real-time scheduling for delivery vehicles. [ABSTRACT FROM AUTHOR]

This paper described the geometric structure of panel data's curved surface in 3D space, and established the synthesized similarity index for the curved surface through several aspects including the absolute magnitude, growth rate, geometric similarity and spatial absolute distance. The traditional fuzzy C-means clustering method was optimized through replacing the distance with the similarity index. On this basis, this paper explored the patent out put type characteristic and the rule of its territorial differentiation in China's 31 provinces (municipalities) during the years of 2000-2010. The empirical results showed that the clustering effect was good, and Chinese patent output showed an upward trend and spatial heterogeneity and autocorrelation generally at the same time no matter in the number, the performance or the growth rate. The innovation capability of more and more regions in central and western China were getting enhanced, although regions with higher innovation ability still concentrated in the eastern China. In addition, the boost of innovation mainly came from governments5 promotion especially the R&D funding investment, however, the allocation of R&D resources and the personnel disposable funds were both extremely unbalanced among regions. Besides, there were distinct differences in the innovation efficiency between eastern and western regions for the financial allocation from government. The government should formulate a reasonable regional scientific and technological development strategy and sets of policy tools according to the regional R&D ability and resource endowment, so as to exploit the regional motivation power of innovation and to improve regional patent innovation capability.

Based on the characteristics of the ordinary evaluation methods and the application of harmony degree equation (HDE), this paper puts forward a new evaluation method called HDE; According to the two common types of the current evaluation methods (classification-grade evaluation method and comprehensive degree evaluation method), the evaluation steps and calculation process of HDE are described respectively. For the classification-grade evaluation method, it can not only be used to the single-factor evaluation, but also used to multifactor comprehensive evaluation by setting the value of HD(y0). For the comprehensive degree evaluation, parameters in the HDE equation can be determined based on specific issues to calculate the HD and then to estimate the evaluation results of comprehensive degree. The application results show that the HDE evaluation method has similar evaluation steps with ordinary evaluation methods, but it has its distinctive advantages. HDE evaluation method can better present the evaluation results and has good universality and flexibility. Obviously, HDE evaluation method can be promoted and applied to the general problem evaluation. [ABSTRACT FROM AUTHOR]
