Responding to complexity and particularity welding on the geometry of TKY tubular node, this paper constructs mathematical model of tubular joint weld of arbitrary section by simplifying the geometry structure, and draws welded joints and ultrasonic sound beam lines based on the actual specifications in order to solve the problems of low efficiency, positioning difficulty, missing inspection and etc. The computeraided simulation technology can realize the visualization in the beam coverage model of welded joints, which can commendably guide the design of ultrasonic phased array inspection and overcome the blindness of the instrument detection parameters, thus improving the effectiveness and pertinence of the actual detection. Study shows that it is beneficial to enhance the effectiveness of the detection tubular joint weld by employment of Visual beam and ultrasonic phased array technology.

Information Coverage

Purpose In this study, the process of crisis information communication is viewed as a systems-based concept. An integrated and systematic three-phase model has been constructed to describe the process of crisis information coverage on the internet. By analyzing factors in the three stages that affect the coverage ratio and speed, this study aims to explore the law of information communication in this process and provide useful evidence for crisis managers to make informed decisions. Design/methodology/approach A complete information communication model has been constructed including the following three stages: crisis information release, crisis information diffusion and crisis information reception. The effects of important factors and variables in the model have been studied, including the crisis information release quantity, crisis information release mode, crisis information diffusion speed and crisis information obsolescence speed. Findings The quantitative analysis shows that crisis information release quantity and diffusion speed are positively correlated with coverage ratio; crisis information obsolescence speed is negatively correlated with coverage ratio; and crisis information release mode affects the speed of coverage but does not affect the final coverage ratio. Originality/value Theoretical value: from the perspective of systems thinking, a detailed, systematic and coupled information coverage model has been constructed. Application value: this study finds the most efficient methods to regulate coverage speed and final rate, knowledge of which may play an important role in guiding the practice of crisis communication management.

In order to overcome the problems of low detection probability, low coverage uniformity and low coverage of current path coverage enhancement methods in wireless sensor networks, a new path coverage enhancement method based on CVT model is proposed in this paper. Firstly, the node perception model and network coverage model are constructed. On the basis of the node awareness model and network coverage model, CVT model is used to adjust the connection mode, density and location of nodes in wireless sensor networks, so as to improve the coverage performance of nodes in the detection area in wireless sensor networks, and realize the effective enhancement of path coverage in wireless sensor networks. Experimental results show that, compared with the traditional methods, the proposed method has high detection probability, high coverage uniformity and coverage rate, and the highest coverage rate reaches 97%, which has higher practical application performance.
