Abstract: Evaluation of the security risks of the Internet had a very important significance to enhance the security level of the Internet and take security measures to eliminate security incidents, and to reduce security risks. After constructing the index system of network security risk assessment, the Dempster synthesis rule was optimized, and the weights of each index system were determined based on D-S evidence theory. In order to verify the reliability of this method, the reliability distribution values of each index layer were synthesized by the optimized Dempster synthesis rule. We can see from the calculation results and Matlab simulation results …that the reliability of the network risk level was significantly improved with the combination rule. Furthermore, the sensitivity analysis was carried out by perturbation method and individual risk factors were adjusted for comparative analysis in two different situations A, B. We can see from the results of comparative analysis that the single factor risk factor had little influence on the whole network risk level, which showed that the stability was better. Show more

Abstract: To enhance the computational efficiency of mobile devices is helpful to realize the application of Ad Hoc network routing technology for video transmission. However, there are still many problems in the application of video transmission based on Ad Hoc network technology, such as the problem of random packet loss caused by node and channel failure. The routing technology which can meet the requirements of QoS technology can be realized in the process of multimedia video transmission. However, because of the deviation in the process of network information transmission and the role of network dynamic topology, QoS routing in Ad Hoc …is provided in the complex process of video transmission. Application of multipath routing protocol based on Ad Hoc can improve the throughput of the network information data and enhance the stability of data transmission.

Abstract: The study on structure optimization design of modified wood furniture tenon structure based on the finite element analysis of ANSYS has a very important significance. On the one hand, it can enhance the functionality of the furniture. On the other hand, it can effectively reduce the destruction of natural resources. Chinese traditional furniture tenon connection technology with widely application and mature process is one of the commonly used connection technologies in China’s construction and furniture manufacturing. After a certain modification of processing, wood used in the production of furniture can meet the demand of density and bearing, which is conducive …to the modernization design of modern furniture. For optimization design of furniture tenon structure through the finite element analysis software NASYS, parametric modeling was firstly made by using a T-shaped tenon structure of modified poplar as the research object, and setting the size of tenon structure. On this basis, the optimization design was carried out step by step, and finally the results of the feasibility design sequence were obtained. From the optimization results, it can be seen that in the final feasible design sequence, the optimal tenon length ratio and tenon thickness ratio were 74.0% and 61.6%. In order to verify the performance of the optimized design results, five groups of tenon structure were processing product and made with the load test. Through the experiment, we can see that the rigidity index of tenon structure showed a decreasing trend and the maximum loading capacity was increased, which indicates that the effect of optimum design is to meet the initial purpose of optimization design.

Abstract: It has been known that when an assisted driving item is added to the Hamiltonian of the main system, the efficiency of the resultant adiabatic evolution can be significantly improved. In some special cases, it can be seen that, only by adding an assisted driving Hamiltonian can the resultant adiabatic evolution work. So it seems that, the additional driving Hamiltonian plays an important role in adiabatic computing. In this paper, we show five kinds of possible forms of the driving Hamiltonian, and analyses the performance of the algorithms. We find that the former fourth kinds of driving Hamiltonian may still …cause the adiabatic algorithm lose their efficiency when the overlap of the initial and final states equals some special value. More importantly, we find that only the final kinds of the driving Hamiltonian can be extended. By modifying its interpolating functions, the final kind of adiabatic algorithm can suit any fidelity of the systems to keep the adiabatic evolution always be valid. Finally, the time complexity of the extended algorithm is better than the original adiabatic algorithm, which owns a constant running time complexity. Although the time complexity is shifted to the complexity of implementing the driving Hamiltonian added. Show more

Abstract: Various analogue models are applied to research the structural evolution of fold-and-thrust wedges. Numerical models are used to explore the fold-thrust wedges and some enlighting research has been made. But combination of the two models have rarely been given sufficient attention. Up to now, landward-vergent thrust wedges, which are uncommon in nature, have not yet been adequately explained and can only be reproduced in a few analogue models under particular conditions. In order to look closer at the formation conditions of fold-and-thrust wedges and to explore the origin of landward-vergent thrust wedges, we conducted a series of analogue and numerical …models under different conditions of substrate. Results of our models revealed that in the frictional basal substrate, and under conditions of a large coefficient of frictional basal, it deformed the fold-and-thrust wedges. Purely landward-vergent thrusting wedge has formed, in the presence of an extremely weak or ductile basal décollement. The number of Landward-fault and fault displacement decreased, when the thickness of the ductile basal increased or the velocity decreased. Show more

Abstract: Speed bump set before truck scale is to prevent the error of weighing measurement caused by truck driver non-standard operation through the weighing platform. However, the vehicle vibration produced by the speed bump will affect the weighing result if the speed bump is closer to truck scale, and can’t play a role in restricting driver’s operation if the speed bump is farther to truck scale. This paper researches the reasonable position of speed bump based on triaxial truck vibration characteristics. Simulation model of vibration in the process of triaxial truck passing the speed bump is built based on the speed …hump model and dynamics model of 5DOF 1/2 triaxial truck. Then vehicle vibration characteristics are researched at the speed of 1.8 km/h, 3.6 km/h, 5.4 km/h, 7.0 km/h, and obtains the vibration decay time with different speed, which determine the minimum distance between speed bump and truck scale. The accuracy of the model is tested on the commercial vehicles safety test platform. The results of simulation and experiment indicate that model of vibration in the process of triaxial truck passing the speed bump can accurately calculate the minimum distance between speed bump and truck scale with different speed, which maximum error is 5.81%.

Abstract: The paper studied the encrypted network behavior recognition and mining in a large amount of network data environment, and proposed a fast online recognition method for the encryption network behavior based on the combination of correlation coefficient and k-nearest neighbor (KNN). Taking the encrypted Twitter traffic as the research object, a lot of encrypted Twitter network behaviors including message sending, pictures sending and other behaviors were analyzed, and then the statistical characteristics to express the encryption network behavior were extracted, and the samples library of encryption network behaviors based on correlation coefficient were established. Then, through the real-time collection of …interactive network data, the correlation coefficient between the interactive data and the sample library were calculated, in order to overcome the noise interference of the similar data traffic. Meanwhile, the data packets after the similarity filtering were classified as the true behavior or the false behavior by using the KNN algorithm, and then the encryption network behavior was identified automatically by the default threshold of the correlation coefficient in big data environment, and compared with the traditional correlation coefficient method, the recognition efficiency of this method was greatly improved, which reaches to about 94%. Based on above, combined with the network vulnerability analysis, web crawler and virtual identity mining, the comprehensive encryption network behavior mining was successfully realized in the environment of big data.

Abstract: According to the demand of hign-precision, and tapered roller bearing is one of the most important components in the mechanotronics, there have a strict requirement for the performance of bearing. Bearing failure is one of the leading causes of breakdown in rotating system. Based on ANSYS/LS-DYNA, dynamic vibration characteristics of tapered roller bearing as the roller generatrix is logarithmic curve are analyzed. The value of vibration acceleration of the tapered rolling bearing with different crowning value of the roller is extracted. During the analysis, the amplitude of vibration acceleration of the tapered roller bearing without crown at start running time …is higher, and it does not tend to a stable state as time goes on. The vibration acceleration changes according to the crowning value of the roller. When crowning value is a specific value, running condition of the tapered rolling bearing will reach a steady state and the value of vibration acceleration is smaller than the other bearings. Therefore, crowning value of the roller is one of the important factors that affect the vibration acceleration of tapered roller bearings. Show more

Abstract: With the development of vehicle active safety technology and its combination with passive safety technologies, there is a need for an updated tool to assess the performance of vehicle safety systems in both the in-crash and pre-crash phases. Consequently, developing human body models with active muscles is critical to achieve improved bio-fidelity simulation results to evaluate the effects of safety systems. In the present study, an innovative human active muscle control model based on a back-propagation neural network (BPNN) controller was developed, and the active muscle response was modelled using a feedback control strategy with the BPNN algorithm implemented in …a human head and neck Sim Mechanics model. The BPNN controller was used to dynamically control the muscle activation level, the most complicated and essential factor in active muscle force calculation based on the Hill equation. Then, the active muscle control model was evaluated by simulating the human response in volunteer sled tests. The results validated the proposed active muscle control method as successful and easily realized. Achieving muscle active control would further improve the bio-fidelity of the human body model.

Abstract: The safety of the mechanical equipment is very important that gives mechanical fault diagnosing technique great significance. This article is focusing on the complex fault diagnosis applied on mechanical equipment. Since it is not easy to make an accurate explanation to the principle component when we use the principal component analysing method to extract the principal component, we use the factor analysis method in Step 1 to do the dimension reduction to the variables. We use Chebyshev’s inequality to do the estimation because we don’t know the variables’ distribution in Step 2. We do the fault diagnosing in Step 3. …We have different options to realize fault diagnosing. We can set a threshold according to our former experiences to do fault diagnosing. And compare it to the normal condition to get the differences thus to finalize diagnosing. We can also go to an expert. This step is called complex data analysing method. We will use this method to check the feasibility of this method. Show more

Abstract: Referring to the issue that the hop value of the range-free DV-hop positioning algorithm could not reflect the distance between two nodes within the communication range, this paper proposes an algorithm named as HCRDV-Hop. According to the proposed algorithm, the distance measured by hops between two nodes is re-treated as the specific value with dividing the received signal strength (denoted as RSSI) between nodes with the maximum average signal strength of nodes ( RSSI ¯ max ). Based on that, we also introduce the mathematical reasoning as well as provide the implementation procedures of the …proposed algorithm. Moreover, the simulation verification is then elaborated in order to evaluate the algorithm performance. According to the simulation result, we discover that the proposed HCRDV-Hop algorithm reveals better performance in the distribution of node positioning deviations and the relative positioning deviations.
