Abstract: Topology clustering, constructing overlay graphs, adding relay nodes, or creating a “small-world” network by building some shortcuts etc, topology control schemes are able to achieve the scalability, resilience, and fault-tolerance for wireless communication networks. In this article, we take a different approach to reach such aim for heterogeneous integrated wireless networks by generating a topology such that the resulting network is “scale-free”. Thereby we propose a topology control algorithm based on the “scale-free” complex network concept and directed proximity graph theory for integrated wireless networks with non-uniform transmission ranges. In this algorithm, the topology is also generated by new nodes’ growth and preferential attachment procedure, but where each new node connects to the existing nodes in its directed attachable proximity in terms of certain probability at each time step. Each node’s directed attachable proximity graph is generated from its directed reachable proximity graph that is built by regulating its transmission power based on locally collected information. The simulation experiments are provided to validate our claims.

Abstract: This paper is to integrate information technology and medical-related technologies to develop a healthcare information system for comprehensive geriatric assessment. This system not only can process geriatric consultation services and ensure that all patient’s information are stored in standardized format , but also provide medical personnel for statistical analysis and processing purposes. This paper uses the Apriori algorithm of data mining for helping doctors to find out the relationship of geriatric syndrome. The systems of this paper can improve increase the timeliness and accuracy of patient care and administration information, increase service capacity, reduce personnel costs, and improve the quality of patient care in geriatric medicine. Furthermore, making the theories and applications of medical informatics will be more extensive and convenient for researcher and healthcare-related industry.

Abstract: The pine is an important tree species in China, while the pine wilt disease is a devastating disease of pine trees. Pine wood nematode (Bursaphelechus xylophilus Steiner & Buhere, 1934 Nickle, 1981) is a world recognized major alien species in the world. It’s from the United States, but pine wood nematode does not seriously endanger the pine in China; the most endangered place is Japan, after several decades of research and control, it has been basically able to control the occurrence of pine wilt disease. The spread trend of pine wilt disease in China grows more and more obvious, which has become an important intrusion pathogenic organism. It not only causes a devastating threats the million hectares pine forest in southern China, but also affects China’s economy and social sustainable development, what’s more, it will damage some of famous scenic spots and cultural heritage sites in China. Meanwhile, the pine wood nematode is a technical barrier, which seriously impacts on China’s import and export trade. The pathogen, pathogenesis, modes of transmission and means of distribution patterns, rapid detection and control methods of pine wilt disease are reviewed in this paper, and we hope that it can provide references for effective control of pine wilt disease in China.

Abstract: Sintered SiC ceramics with difficulty, and its production process and production are more expensive, lower sintering temperature of SiC ceramics and look for new low-cost production process is the focus of materials research workers. Re-crystallization of SiC components of the raw materials requirements of high purity, can not add sintering aids, sintering temperature up to about 2450°C). In this paper, by improving and optimizing the existing production process, to lower the sintering temperature of the new methods and ideas, the study shows that: β-SiC will be added to the sintered α-SiC slurry, and the best particle size ratio of α: β = 15:1 mixture, at the same time, according to re-crystallization of SiC sintering theory, the fine particles (β-SiC, has played the role of sintering agent) adsorption in the coarse particle (α-SiC, the role of the support skeleton) and can greatly reduce the SiC Sintering temperature (50-100°C), and to improve the purity of α-SiC, the most economical way to prepare a high-density, high oxidation resistance, high impact resistance, high strength, high mechanical properties of recrystallized SiC powder .

Abstract: In order to examine applicability of the Reynolds-Averaged Navier-Stokes (RANS)using Reynolds Stress equation Model (RSM) and the Large Eddy Simulation (LES) in numerical simulation of centrifugal pump, a series of 3D numerical simulation at the design point and at six off-design points were carried out with the two methods. The object is based on IS80-65-160 centrifugal pump. According to the results obtained, head, shaft power, efficiency of pump were calculated, the simulated performance curves of a centrifugal pump is processed. The simulated performance curves of a centrifugal pump were compared with the experimental performance curves. It was confirmed that RANS were suitable for the numerical simulation of the internal flow inside a centrifugal pump. But the result of LES is not very good if the same gambit which is suitable for RANS was used. Therefore, the computer resources, not propose the Large Eddy Simulation (LES) method in numerical simulations of centrifugal pump.

Abstract: Distributed routing can find multicast tree and adapt to dynamic changes of multicast members in case of acknowledge local network state. Majority of current distributed multicast routing algorithms based on the shortest delay, which can achieve load balance large additional overhead. The paper presented a kind of load balance multicast routing algorithm based on distributed computation and centralized control. It reside computation Agent in each node to compute forward probability and to maintain node routing table, node state table and forwarding probability table. In addition, it can detect delay of adjacent nodes and coordinate session establishment based on the copy, parameter transmission and notification of control Agent. On this basis, the algorithm achieved dynamically joins and leave session of multicast members. Algorithm analysis results show that the algorithm can improve the overall efficiency of network transmission.

Abstract: Taking TWERD frequency converter as research object, the working principle and fault types of three-phase SPWM inverter are analyzed. Its output line voltage waveform in normal operation and fault condition is studied. According to the fault information and the different data of input and load changes, the frequency converter output line voltage waveform is decomposed by wavelet transform. The low frequency energy value is picked-up and regards it as eigenvector. The mapping relationship between eigenvector and fault types are established by BP neural network, the fault bridge and fault location of frequency converter are found. Simulation results show that the diagnosis accuracy is 96.5% after training 46 times. Fast convergence speed and high precision is obtained.
