As ICTs continue to enter the classroom, the interaction between teachers and students in the classroom is changing. The purpose of the study is to find out what the important teaching&learning activities are in such classrooms, and whether there are stable interaction patterns in these activities. In order to achieve this goal, the Flanders interaction analysis system (FIAS) was transformed in the study, and based on the data generated by the FIAS, we carried out sequence and frequency analysis with PHP programming language. For visualizing the research results, we produced the adjacency graph of teaching&learning activities using network analysis technology and the Gephi software. In addition, we analyzed the two web-based classrooms using the above method. The conclusions are as follows: It is an effective teaching method to require students to evaluate according to the work submitted using the Internet. The use of educational websites or special topic software is a common feature of both classes. A more fixed sequence of activities in these kinds of classes is that the teacher first adopts the opinions of the students, then raises open questions and then responds positively. Keywords-Flanders Interaction Analysis; Web-Based Classroom; Teaching & Learning Activities; Network Analysis

In order to change the traditional fault diagnosis form and realize on-line fault diagnosis, a fault diagnosis architecture of box transformer substation based on Internet of Things(IoT) technology is proposed. This architecture is a three-layer fault diagnosis framework of box transformer substation including the perception layer, the transport layer and the application layer. This paper analyzes the online fault diagnosis process of box transformer substation under the IoT architecture and its key technologies. Through the IoT technology to realize the collection of information data and online fault diagnosis of box transformer substation operation, the box transformer substation can be processed quickly, in real time and accurately when it fails, to prevent system fluctuations and catastrophic accidents, and provide necessary basis for planned maintenance, so as to extend the service life of box transformer substation and improve the operation efficiency.

The heat generated during the working process of the relay directly affects the mechanical strength of the metal material and the dielectric strength of the insulating material. Sealed electromagnetic relays tend to be miniaturized. The effect of temperature on its working life is getting stronger. Therefore, it is very important to analyze the thermal characteristics of the main components inside the relay. The mathematical model of the thermal field is established by analyzing the heat transfer mode of the sealed electromagnetic relay and the boundary conditions of each component. The finite element model of the relay is established by the ideal equivalent method. This model has higher computational efficiency and accuracy than traditional computational models when performing thermal analysis. The temperature field of this model is studied by thermoelectric coupling method. The effects of ambient temperature and current intensity on the steady-state temperature field and transient temperature field of the sealed electromagnetic relay are discuss separately. The simulation results show that the ambient temperature is independent of the temperature distribution inside the relay and the current intensity will affect the main heat source type inside the relay. The research method of this paper can provide technical support for thermal characteristic analysis in the design stage of sealed electromagnetic relay. Keywords-Sealed Electromagnetic Relay; Thermal Analysis, Temperature Field; Heat Source

In the current study of two-dimensional aerostatic motion platform, there are problems such as poor uniaxial motion straightness, poor two axis verticality accuracy and small bearing capacity. In this study, a two-dimensional aerostatic motion platform with precision box plate as its structural reference was designed. It is designed with integral aerostatic guideways, and all components are based on precise granite box plate. It uses the high planeness, parallelism and perpendicularity of the precise granite box plate itself to ensure the linear accuracy of the moving guide and the perpendicularity between the two moving guides. And the aerostatic motion platform is driven by linear motor, which eliminates the error caused by traditional mechanical transmission. This two-dimensional air floating platform features high stability, high motion straightness, easy installation and maintenance, and can be widely used in precision machining and precision measurement. Keywords-Closed Aerostatic Guideways Two-Dimensional Aerostatic Worktable; Precision; High Stiffness; Box Plate

At present, research on the reuse of design information resources mainly focuses on the representation and modeling of its information. Neglecting the design information itself can be used as a starting point for design reuse. Based on the existing instance model of the enterprise, this paper firstly divides the function of the instance model; it uses the fuzzy clustering analysis method to classify the existing instance model in a fuzzy manner; then decomposes the customer requirements and compares the similarities to determine the reuse example. The model alternative set; finally, the fuzzy decision method based on the basic feedback extension is used to find the optimal scheme, and the scheme of the selected design reuse model is improved and used as the final scheme of the new model design. This paper takes the design reuse process of consumer drones as an example to verify that this method has certain feasibility and effectiveness.

At present, in ROS core framework system, the realization of autonomous cruising and obstacle avoidance is the only way for robots to become more perfect. For this reason, this paper proposes and establishes a physical model of a two-wheel differential-driven mobile robot with nonholonomic motion constraints. SLAM and autonomous navigation are simulated, verified and optimized on STDR and Gazebo platforms, and gmapping and amcl algorithms are selected to realize mapping and navigation on Cater prototype platform. According to the experimental results of simulation verification and optimization, it is shown that using the above platform and algorithm to give the robot an environment map can basically realize accurate positioning and real-time motion planning for positioning targets. In the verification of the prototype, the experimental results are consistent with the theoretical analysis. The feasibility of the method applied in this paper is proved.

In order to improve the accuracy and efficiency of vascular 3D model reconstruction, an improved method is proposed to solve the ambiguity problem in the surface rendering process. Based on the researches on the expression method of surface rendering process, the causes for the ambiguity were analyzed firstly. Then an improved method for surface rendering was proposed, whose reliability was verified by experiments. Besides ensuring the effect of reconstruction, this method can improve the efficiency of the surface rendering process. With this method, the visualization of medical images was performed more efficiently. Furthermore, the more accurate subsequent 3D printing process for blood vessel is predictable.
