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 optimization of micro milling electrical discharge machining (EDM) process parameters of Inconel 718 alloy to achieve multiple performance characteristics such as low electrode wear, high material removal rate and low working gap was investigated by the Grey-Taguchi method. The influences of peak current, pulse on-time, pulse off-time and spark gap on electrode wear (EW), material removal rate (MRR) and working gap (WG) in the micro milling electrical discharge machining of Inconel 718 were analyzed. The experimental results show that the electrode wear decreases from 5.6×10-9 to 5.2×10-9 mm3/min, the material removal rate increases from 0.47×10-8 to 1.68×10-8 mm 3/min, and the working gap decreases from 1.27 to 1.19 μm under optimal micro milling electrical discharge machining process parameters. Hence, it is clearly shown that multiple performance characteristics can be improved by using the Grey-Taguchi method. © 2013 The Nonferrous Metals Society of China.

A numerical drawbead model developed in sheet metal forming simulation was introduced. According to the similar effect between an equivalent drawbead model and a spring, a spring element was adopted to treat the drawbead process in the incremental dynamic explicit method. The treatment can consider the drawbead passive effect in real-time and synchronously to reflect the sheet metal flow law. The results of practical automobile panel show that the numerical drawbead model can simulate the development of local wrinkling in deep drawing with higher precision.

The Taguchi method was applied to analyze the optimum process parameters of a 3 mol% yttria-tetragonal zirconia polycrystal (3Y-TZP) containing 30 wt% titanium nitride (TiN) (3Y-TZP/TiN). Four process parameters - (1) sintering type, (2) crushing time of TiN powder, (3) the first-step sintering duration, and (4) the second-step sintering temperature were chosen as the controlling factors. Fracture toughness, flexural strength, hardness, relative density, and electric resistance were examined using an L9 orthogonal array. The results indicated that the fracture toughness was mainly affected by the duration of the first sintering step. The highest fracture toughness (9.275 MPa m1/2) was achieved at 97.3 vol% of the tetragonal phase in 3Y-TZP/TiN. In addition, 3Y-TZP/TiN possessing a high fracture toughness of 8.59 MPa m1/2 and a flexural strength of 680.77 MPa was fabricated using the optimum process parameters, 8 h crushing time of TiN powder, and the two-step sintering process. The electric resistance for 3Y-TZP/TiN was 3.26×10-3 μm cm. © 2013 Elsevier Ltd and Techna Group S.r.l.

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.

In order to study the effect of the microstructure with Al and V added TiN coatings, TiN, TiAlN and TiAlVN coatings were deposited on AISI M2 high-speed steels by magnetron reactive sputtering. The microstructures of all the coatings were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The results indicate that the addition of Al into TiN coatings reduces their lattice constant, but a further addition of V into TiAlN coatings increases their lattice constant. Moreover, the growth morphologies for TiN, TiAlN, and TiAlVN indicate that adding Al and V has a tendency to improve the columnar structure. The (111) and (200) orientations of TiN, TiAlN, and TiAlVN are identified. The ε(Fe3N-Fe2N) phase occurs because a small amount of Fe is present in the coatings. The interlayers of TiAlN and TiAlVN have the preferred orientation. The texture (columnar) structure of the (111) and (200) orientations is observed in the TiAlN and TiAlVN coatings. An orientation relationship of (01 0)α-Ti//(110)T.M occurs between the interlayer and tempered martensite (T.M) in TiAlVN. © 2014 The Nonferrous Metals Society of China.
