The electromechanical-electromagnetism hybrid simulation technology combines the advantages of electromechanical transient simulation and electromagnetic transient simulation. It can coordinate the simulation scale, precision and speed and provide new ideas and ways to study the stability and dynamic of large-scale power system characteristics. Aiming at the shortcomings of the existing hybrid simulation method, this paper presents a method of mechanical-electromechanical transient hybrid simulation based on socket technology. First of all, using the PSCAD with the component graphics library to build flexible AC transmission system (FACTS) components, its controller circuit, and its precise electromagnetic transient simulation; using the PSAT toolbox of MATLAB to build a conventional AC network for its mechanical and electrical transient simulation. Secondly, the hybrid simulation interface algorithm is improved. The hybrid simulation method simplifies the interface design, which can be flexible and efficient to carry out mechanical and electrical transient - electromagnetic transient hybrid simulation, and has a high degree of scalability. Finally, a threemachine nine-node system with SVC is used to simulate the electromechanical transient-electromagnetic transient simulation algorithm of power system based on socket technology. By comparing and simulating the three-machine 9-node system, the simulation results show that the proposed method can accurately simulate the FACTS-based simulation method, and the simulation results show that the proposed method can accurately simulate the FACTS Physical and dynamic characteristics of fast transient processes after disturbing AC systems.

This study intends to study the properties of chemical grouting materials in civil engineering. For this objective, a flat fracture model under the condition of dynamic water is established, and on the basis of the model, theoretical derivation and the injectivity analysis based on Fluent is made, so as to study the flow characteristics of the slurry, as a supplement to the grouting theory. The results show that the diffusion form of slurry is wide before and narrow behind, which is similar to an ellipse. Groundwater flow is large, grout diffusion area will be narrower and the slurry is more easily diluted, which is not conducive to water grouting. The greater the grouting pressure is, the greater the degree of open fracture will be, the smaller the viscosity is, and the smaller the groundwater pressure is. All of these are beneficial for the slurry diffusion. The grouting pressure is a constant. With the increase of grouting time, the flow velocity of the slurry front decreases and it is gradient. The grouting pressure at the grouting hole is the largest, and with the slurry diffusion, the slurry pressure decreases and decreases gradiently. In a word, the grouting method can well test the properties of chemical grouting materials, which has great practical value. Copyright © 2017, AIDIC Servizi S.r.l.

In order to improve the accuracy and convergence speed of the transient estimation of the power system, taking into account the nonlinearity of the system, the Kalman filter (EKF) algorithm which is mainly used in the current status estimation of the power system, has the disadvantages of slow convergence and poor robustness, using particle filter (PF) algorithm in this work. In order to solve the problem of computationally occupied space and large amount of computation and sample degradation, a particle filter algorithm with sequence importance resampling is introduced on the basis of basic PF algorithm, which is closer to the approximate expression of true distribution of status. Compared with the EKF algorithm, the power system can converge to the real value quickly after the disturbance of the power system, and it has higher estimation precision and stability than the extended Kalman filter algorithm, achieving the requirement of accurate estimation.

In this paper, we study the issues of the diversity capacity of multi-input and multi-output wireless networks based on the cooperative transmissions. We set up the cooperative transmissions model for multi-input-multioutput wireless networks, and estimate the expressions of diversity capacity of wireless networks. We prove the diversity capacity of multi-input-multi-output wireless networks will be increased by the cooperative transmissions, and we give the criteria to discuss further application of the scheme, such as cooperative selection. Theoretically, we prove the strategy can ameliorate the capacity of the system.

In view of the problems of easily being caught in the local optimum and long operation time of standard simulated annealing algorithm in the gear weight optimization process, this paper put forward an improved genetic and simulated annealing algorithm with the function of disturbance. Firstly, it used Cauchy distribution as the theory of disturbance distance to process the distance between current division and new division so as to reduce the computation complexity of internal circulation. Then genetic algorithm with mixed single point crossover operator is introduced to enlarge the searching space of population. Finally, the advantages of improved genetic algorithm and simulated annealing algorithm are combined to establish the gear weight optimization design model. The simulation experiments show that improved genetic algorithm and simulated annealing algorithm has better result in gear weight optimization and higher working life compared with traditional simulated annealing algorithm.

The ability to improve the information transmission is not the advantage of food retail chain enterprise information management system, how to ensure the quality of food retail chain enterprises have become the focus of today. Based on this, in this paper, the methods of questionnaire and mathematical statistics, food retail chain enterprise information management system of our country are discussed in this paper, the questionnaire covered most provinces of China 50 retail food chain, in view of the enterprise informationization construction condition and the security of food quality management research. Results show that more than half of the enterprises will choose ERP system, mainly on information collection processing has obvious advantages. But the quality of management with serious defects. To the retail chain enterprise should strengthen the system in the future on the quality of management ability, so as to better adapt to the demand of the market. © 2016 IEEE.

The vulnerability assessment is a key segment that should be considered in advance of any security problem. Since experiences of attack in wireless communication networks are still limited, a complete model of vulnerability assessment for wireless communication networks is needed. In this paper, the attack graph and conflict graph are introduced to deal with the vulnerability assessment. The overall vulnerability assessment is decomposed into two parts. One is the vulnerability analysis model for wireless communication networks using attack graph and conflict graph. Another one is focused on the formula and solution, and the formula is proposed to value the vulnerability factors derived by the vulnerability assessment model.
