Abstract: The development of private colleges and universities affects structural reform and changes the trend of higher education. To study the running level of private colleges and universities, an empirical study must be conducted. First, statistical information from 23 Shandong Province private colleges and universities was collected, and an index system of education level with six primary indicators and 13 secondary indicators was constructed. The index data were standardized through a statistical analysis software. Analytical hierarchy process was adopted to determine the weight of the evaluation index and test the consistency of the judgment matrix. A fuzzy comprehensive evaluation model was …established, and the building evaluation set was improved. After confirming the membership matrix of the fuzzy relation, multi-index comprehensive evaluation and comprehensive ranking of private higher education level in Shandong Province were carried out. The improved traditional fuzzy comprehensive evaluation method can be used in evaluating the performance of private colleges and analyze scientific rankings. Results of this work have high theoretical significance and application value. Show more

Abstract: Storage software and products design/architecture from different storage vendors are often incompatible. This incompatibility of the heterogeneous storage makes the remote disaster recovery infeasible, which results in a lot of wasted storage resources and excessive duplication of investment. To solve the problem of incompatibility for remote disaster recovery of heterogeneous storage, this paper proposed a solution. The feasibility of the solution has been testified by the implementation of a practical case. Accordingly, this scheme can reach six disaster levels and meets the requirement of recoverability, reliability and real-time performance indicators.

Abstract: Wireless sensor networks (WSNs) are envisioned for a number of application scenarios. However, the few focus on the features of a specific system, and rarely report about the characteristics of the target environment. This article presents an unequal clustering and cross-layer routing protocol for environmental monitoring based on WSNs under coal mine laneway. Considering the long and narrow structure of the road tunnels, a chain-type topology is developed to achieve an application-aware system. In order to improve the performance and prolong the lifetime of the network, an energy balancing strategy is deployed in the cluster head nodes. The mechanism of …unbalanced energy exhaustion among cluster heads in the whole network is theoretically analyzed, and the effective density function (ρ  (x )) is calculated, which is used for cluster head election in order to make the distribution density of cluster heads correspond to. In addition, a cross-layer routing algorithm is presented, which considers routing and MAC layers information to reduce the congestion, increase the packet delivery ratio, and minimize the energy usage. Simulations show that the proposed scheme outperforms other algorithms in terms of energy balance of average node, prolonging the network lifetime and better network throughput. Show more

Abstract: An effective method for reverse engineering message format specification is proposed, which is a necessary step to extract the protocol’s state machine. First, separators are scanned and compared to accomplish protocol fields partitioned hierarchically, so as to determine the field boundaries recursively and achieve the basic field; second, the protocol candidate tokens are extracted by frequency statistics; finally, the logic feature selector is designed for filtering the logic feature keywords. The experimental valuation demonstrates the validation of partitioning fields and extracting logic feature keyword.

Abstract: Web Service diffusion is becoming an important way of Web information share. Because of the existence of large malicious nodes and Web services in online social network, the service diffusion in social network has got great trust crisis. It hinders the sharing and reusing of services in online social network. In order to improve the credibility and the speed of service diffusion in social network, we divide the nodes into common nodes and optimizational nodes by utilizing the trustworthy relationship among social network nodes. The algorithm is designed to find optimizational trustworthy nodes which have better trust values and better …diffusion characteristics. Based on the optimizational trustworthy nodes, in the case of the trust, the diffusion speed and other factors, the trusted service diffusion is achieved by the algorithm. Therefore, the trustworthy services will be quickly diffused. The results of the experiments demonstrate that the diffusion model and our algorithm are correct and effective. Show more

Abstract: With the development of metro, the construction of subway tunnel and station have to cross the crowded building group. For different crossing existing structures, such as undercrosing, upcrossing and side-crossing engineering, the adjecent existing structures would be influenced unavoidably. It is important for adjecnt existing structure that the deformations and stabilities of them are controlled during the metro construction. So, according to one side-crossing engineering project, based on numerical simulation and model test method, the deformation of support structures of metro station are studied, and the impact of station side-crossing on adjecent existing undergroud structures are discussed in different construction …methods.

Abstract: This paper investigates the enforcement of regulator using an appropriate penalty, in the framework of game theory, to force a polluting firm to act in a socially optimal way. In most related literature, the penalty is considered to be only related to the degree of pollution. In such a case, a stable equilibrium fully complying with environmental regulations is unreachable. Hence, a completely restraining penalty (CRP) is proposed in this paper to reduce the probability of the firm’s violating behaviors under the penalty mechanism with suspension of production (SOP). This statement is proved by introducing the concept of ɛ -Nash …equilibrium. A set of simulation studies is conducted based on System Dynamics to verify the model. Conclusions derived from the simulation study give us further insights into the relationship between penalty and dynamic game. Show more
