Transient stability assessment of power system is the precondition of analyzing system transient stability, and it is the basis of effective analysis of power system transient stability. In order to better understand the operating state of the power system, this research builds a pinball loss SVM model based on the traditional SVMA algorithm to evaluate the transient stability of the power system. On this basis, the research takes a group of wind turbines as an example, and analyzes the calculation examples to verify the effectiveness of the pinball loss SVM model. The results show that the time limit of the proposed model is less than 10 seconds, and the average accuracy is about 94%. It can quickly and effectively evaluate the power system transient stability. It is hoped that this study can provide some reference for the evaluation of power system transient stability.

With the increasing demand for the use of automatic instruments, the detection of instrument accuracy is also indispensable. The traditional manual verification to complete the detection of power instruments is inefficient and gradually unable to meet the demand. During the automatic verification of power meters, it is necessary to use a monocular camera to collect and process the pictures of the meters, obtain the verification data and store them into the database, thereby achieving the acquisition of the meter readings. In this paper, we introduce a reading recognition method for digital multimeter. For the character recognition of the digital tube, a number can be divided into seven parts numbered 1--7, and the number can be obtained by sequentially identifying the seven parts and then comparing the results with the data table. In this way, the proposed method can quickly recognize the reading of digital multimeter.

At present, Internet applications generally use "name and citizen ID number" to identify the online users. Although it plays a unique role in distinguishing subjects, it also causes large-scale personal information disclosure, which frequently leads to identity theft, account theft, telecommunication and network fraud. To deal with these problems, the article proposes to use eID digital identity to build a national unified digital identity system, and elaborates the design principle and application of eID digital identity.

This paper is about a 3D scanner system which can be used to build the prosthetic leg model, which can effectively capture details of the amputated leg. It is a multi-camera scanning system that can scan the amputated leg and has the following strength: quick scan, ease operation, data reliability and low cost. A scanner base is designed to hold all the cameras and Raspberry Pi. The scanner base should be able to rotate, adjust the shooting angle, and adjust the distance between the camera and the object. The images obtained by cameras can be transmitted to the PC through the Putty and FileZilla. Then the images can be processed on the Autodesk Recap to get the depth of field information of the object and build the 3D model. The principles of the image-based modelling techniques also illustrated in the paper. The 3D model of arms have been generated successfully by the designed scanner and it proves that this scanner is a potential solution for designing and manufacturing the prosthetic leg. The graphs of errors in the main part show that the error is small which is in an acceptable range.
