Abstract: Acupuncture is a complementary treatment method, while its therapeutic effect is tightly related to physicians manipulation skill. Lifting and thrusting manipulation is an important acupuncture procedure which could enhance the outcome, e.g. the arrival of Qi. Traditional methods cannot quantitatively measure acupuncture manipulations which make difficult in teaching and studying. In this paper, we proposed a high precision and quantitative monitoring system based on commercial haptic device. Our system can obtain quantitative position, velocity and force information and visualize the lifting and thrusting manipulation in real time. As a simple but accurate recording solution, it would be useful in accumulation and investigation of experts' experiences.

Abstract: Urban rail transit plays an important role in daily life and optimal emergency scheduling determines social and economic benefits. To solve emergency scheduling problem of urban rail transit, a mathematical scheduling model is proposed in this paper. Based on the characteristic of urban rail transit, this scheduling model considers the benefits of both passengers and rail transit operator. Furthermore, on the basis of the model, three sorts of emergencies, such as closure of stations, outage of metro lines and surge of passenger flow are described and formulated, thus, model is solved through several GA operations. The testing results show that the model can accurately reflect the change of rail transit network during emergencies and quickly provide an effective emergency scheduling scheme.

Abstract: Network security audit is an important part in network security system, which, to some extent, makes up for the deficiencies in firewalls and intrusion detections. According to the characteristics of the network data, the traditional decision tree model is modified, and the application pattern in which the decision tree model is used to network data security audit is also proposed. Simulations show that the decision tree classification model not only is adaptive to the characteristics of network data, but also can prevent malicious attacks effectively. The effects of the attributes such as IP, port, and protocol type on classification are also uncovered.

Abstract: The main objective of this paper is to establish several nonlinear difference inequality, which includes nonlinear functions of u (n) and provide explicit bounds on unknown functions. This inequality given here can be used as tools in the study of difference equations with the initial conditions.

Dynamic visualize Prime algorithm and kruskal algorithm implementation process. Around two window synchronization of animation, " in order to find the minimum edge " list box list the minimum edge of a minimum spanning tree ,with thick line in the left window drawing the found minimum edge and On the edge of the vertex, in the right box demo the process of algorithm dynamic execution.

Abstract: Sarma method is used to calculate the slope and dam stability of widely used methods, wherein a spreadsheet is typically utilized to solve the safety coefficient. Spreadsheet calculation of safety factor in programming efficiency is significantly low, although some correction methods of Sarma use Newton iterative solution. However, the algorithm is extremely complicated for programming and engineering applications, thus making the work difficult to complete. Based on traditional Sarma method, this work uses defined derivatives in Newton iterative to determine the safety factor and obtain the corresponding derivation formula. Through programming and inputting a random initial value, the iterative solution can provide the slop safety factor. Examples also show that the convergence of iteration is rapid and the iteration can reach its required precise value in 2 to 4 steps. The results obtained using the classic examples of Sarma method are exactly the same. The method for calculating the safety factor of Newton method usage is suitable for people who are familiar with traditional Sarma method. The process is simple, direct, effective, and precise.

Abstract: In the current multi-level security database system, the BLP model is the most widely used security model. For the problem of data redundancy, primary key loophole and reasoning channel of the BLP model, an improved method is proposed. The proposed method consummates the read-write level and the read-write range of user, increases the audit mechanism, eliminates the primary key loophole and avoids the reasoning channel to some extent. The proposed method in this paper improves the security of the BLP model and makes the security model more practical.

Abstract: The ontology construction methodology frameworks used so far are limited in certain domains lack of mature knowledge hierarchy and require the reference alignments to be specified manually. This paper presents a constellation graph based method to build ontologies including two critical steps: transform the property of the concepts abstracted into the corresponding data; draw a constellation graph based on the data and the classes in the same constellation part constitute a new kind of classes. This approach can facilitate ontology construction process with little human efforts and be more time-saving. A practical example is used to illustrate the performance of this approach.

Abstract: A production line and its MRO for career apparel industry is studied. Some modular units well organized by the department of equipment are integrated into the production line, and the bottleneck tasks are adjusted by means of operations study techniques. The line is balanced by the lines balancing technology. A hybrid layout mode with production lines and modular units is given to provide efficient preparations of equipment and tools and easy maintenance plans.

Abstract: Considering the integrated medicine supply chain, and introducing the government limit pricing and subsidy mechanism, the pricing strategy of integrated medicine supply chain was studied in this paper. And the optimal strategy in the face of market fluctuations caused by unconventional emergencies based on government regulation was given. The study shows that, under different subsidy levels, the optimal production volume, retail price and profit of the supply chain are related to production cost, market size, government regulation and government subsidy; governments limit price regulation on medicines is welfare for both consumers and retailers, and it is favorable for medicine supply chains normal development.
