With the VPN technology is widely used by enterprises and individuals, in order to guarantee the security of data transmission, VPN traffic has characteristics of encryption and privacy, but due to the increasing intensity of encryption, VPN routing protocol for the audit is more and more difficult, so the security of VPN network security technology has become a restricting factor for VPN protocol identification. In the field of VPN protocol recognition, the identification of encrypted data in VPN protocol is a key. Therefore, a new self correlation randomness detection algorithm is proposed in this paper.

Aiming at the shortcomings of traditional methods, this paper proposes an elevator traffic pattern recognition method based on density peak clustering algorithm. This method uses the cluster analysis of the passenger flow data of the previous week to obtain the cluster center coordinates of the corresponding traffic patterns. For real-time changes in elevator traffic data, using 5-minute passenger flow data, the cluster centers are selected based on the highest density and farthest distance from the higher density points, thereby identifying the current traffic pattern. Experiments show that the method can effectively recognize the elevator traffic pattern, is easy to implement, has fast calculation speed, and has a stable clustering effect, and can meet the real-time requirements of the group control system.

In recent years, China’s dangerous Chemicals transportation accidents have occurred frequently, and road transportation comprised a large proportion. We collected 982 cases of hazardous Chemical road transport accidents from 2013 to June 2018 and summarized the characteristics of accidents. We also analyzed the characteristics and laws of accidents in terms of sections, provinces, road types, hazardous varieties, loading, accident causes, accident consequences and accident emergency disposal time. The results show that the road transport accidents of hazardous Chemicals are closely related to the initial trafflc accidents. Rollover, tracking and impact are the main trafflc accidents. They usually develop the way of rollover-leakage, tracking-leakage, impact-leakage. Aiming at the evolution process, a map of probabilistic accident chain is drawn to reveal the probability distribution of various types of accidents in hazardous road transport and the weak points of accident evolution. Relative preventive measures are being proposed as well.

Comparing with the traditional summative assessment, the continuous assessment is a minor assessment method in universities around the world. In the Faculty of Engineering and the Built Environment, University of Johannesburg, South Africa, the Department of Electrical Engineering Science applied the continuous assessment in the past five years in order to achieve better study performance while the Departments of Mechanical Engineering Science and Civil Engineering Science are still using the traditional summative assessment. It is necessary to analyse the performance of these two different assessment methods to find which method is better or more stable. In this paper, the traditional summative assessment and the continuous assessment are investigated and compared based on the pass rate of the modules/subjects of these three departments. The histograms and Wilcoxon signed-rank test are used to analyse the differences of these two assessment methods. From the statistical results of this case study, the pass rate of the traditional summative assessment is more stable than the continuous assessment. Finally the unexpected performance of the continuous assessment is investigated.

KNN (K Nearest-neighbor Classification) is a lazy learning classification algorithm, where it only memorizes the training dataset instead of providing a defined discriminative function. KNN tends to search the nearest neighbor(s) for a target in the entire training set, hence, the prediction step of KNN is quite time consuming. KD-tree (K Dimensional-tree) is a multi-dimensional binary tree, which is a specific storage structure for efficiently representing training data. Therefore, the paper takes the advantages of KNN and KD-tree and then proposes a new classification algorithm called KNN-KD-tree. Eleven datasets have been adopted to conduct experiments. The experiments have shown that the proposed KNN-KD-tree algorithm can efficiently reduce time complexity and significantly improve search performance.

In recent years, the accident statistics of shield tunneling in China's subway tunnels show that the collapse is the most frequent type of accident in subway construction projects. Once it occurs, it often results in group bodied injuries and major economic losses, and the social impact is serious. Due to the disturbance of the surrounding soil caused by the shield construction, uneven settlement on the ground and protective measures were not developed in time and then evolved into high-accident, high-caused collapse accidents. In addition to the engineering geological conditions in the shield construction, the tunneling speed, cutterhead torque, soil warehouses pressure, simultaneous grouting amount, simultaneous grouting pressure, and other parameters in the shield construction are also the main factors affecting ground settlement. This paper analyzes the grey connection degree between the settlement monitoring of a metro shield construction and the shield construction parameters in a certain city. It is concluded that the most important factor causing ground settlement is the pressure of the earth storage, and corresponding preventive measures are proposed for the subsequent tunnel shield construction. It is instructive to reduce surface subsidence and prevent it from becoming a collapse accident.
