Authors: Zhang Tao 
Published: April 2021

Abstract
This paper studies the coordinate system of the KUKA robot workpiece. According to the mathematical model of the robot system workpiece coordinate system, with the help of the CATIA software, the workpiece coordinate system is established. Through the solutions of the direct and inverse kinematics problems of the robot, the method of approaching the workpiece coordinate system is obtained. By setting the angles of A1, A2 and A3, the robot end actuator can reach the corresponding position of the workpiece coordinate system, and by setting the angles of A4, A5 and A6, the robot end actuator and the workpiece coordinate system can be adjusted to form the attitude relationship. Finally, the feasibility of the above method is verified by applying the program of KUKA robot to cut automobile ceiling panel. The results show that the robot workpiece coordinate system can be established offline by using 3D CAD software, by adjusting the angle of six axes of the robot, the robot end actuator can reach the designated position of the workpiece coordinate system and get the required attitude relationship.

Abstract
Failure analysis of cracking of a GIS aluminum shell which causes SF6 gas leak in a 220 kV substation was present. Visual inspection, microstructure observation, chemical composition and mechanical properties characterization were performed to reveal the forming mechanism of the crack. It is found that the crack is located in the region of the aluminum alloy shell that undergone welding repair. The crack is continuous and develops within the weld metal. Detailed investigation reveals that the crack initiates by the defect of lack of fusion in the welding repaired zone. The working stress induced by gas pressure, combined with the residual stress and vibration stress, results in the extension of the crack and the final leaking of SF6 gas.

Published: April 2021

Abstract
This study focuses on the determinants of community behaviour towards ICT-oriented applications - Volunteer Smartphone Patrol (VSP) PDRM as a medium to submit complaints. The VSP application has spanned four years since its launch in May 2016, but the community participation as a consumer is still low and far from the target set by the government. Registered members were also found to have less use of this application in making complaints and reports to the Royal Malaysian Police (PDRM), especially in dealing with criminal issues that occur within the community. Therefore, this study was conducted to find out if there is a relationship between factors that influence the intention of the community to use the PDRM VSP application. This study uses the Unified Theory of Acceptance and Use of Technology (UTAUT) by [1] as the basis for the formation of variables and research framework. The data were obtained from questionnaires distributed to 155 respondents living in the state of Kedah. The findings show that there was a significant relationship between factors that influence the intention to use VSP. The results of this study also found that the expectations of the effort and the conditions of the facility had a great influence on the intention to use VSP applications. Therefore, the study emphasizes that with the availability of better VSP applications, the effectiveness of PDRM service delivery to the community in the state of Kedah can be improved.

Published: April 2021

AbstractCommunication is carried out not only directly through face to face, but also non-face to face or in writing. Where verbal communication consists of oral and written communication with these two things, written communication through social media is part of verbal communication but non-face-to-face (Anggriawan 2017). Communication using chats, letters, or emails as an example of a communication medium. With the existence of communication through social media individuals and organizations cannot be separated from the existence of communication through social media, including political parties. Along with the existence of artificial intelligence, which is very close to individual and organizational communication, on this occasion the researchers want to see communication during the Legislative General Election in 2019 at the national level. Does the communication through Twitter conducted before the general election can affect the results of the legislative elections for the three parties consisting of the National Democratic Party, thePKS, and thePDIP. The method used is the descriptive qualitative method, using NVIVO analysis. With the existence of non-verbal communication, the communication of political parties participating in the election has various influences on the results of legislative elections, some of which increase and some also decrease. The three parties that are active in communication using artificial intelligence (Twitter) have shown an increase in the results of legislative elections. The National Democratic Party increased by 1.59%, PDIP increased by 1%, while PKS increased by 1.82%. Therefore, the increase in communication through artificial intelligence influenced the results of the legislative elections.
