Establishment and Solution of the Error Model for Delta Parallel Robot
Published 2015-01-01“…In order to analyze the influence on absolute positioning accuracy of kinematics parameter errors of the delta parallel robot,apose error model is established and solved.Taking the transmission branch chain as serial mechanism,the kinematics model is solved by establishing D-H transformation matrix.By bringing the micro displacement of the slave arm into the D-H transformation matrix,on the basis of the uniqueness of the pose error of the mobile platform,the error model is established in the form of linear equations.In the end,taking a type of delta parallel robot as example,this model is validated by analyzing the pose error that caused by angle error of the gearbox mounting end face.This pose error model can serve as an analysis tool for the further research of precision analysis and error compensation.…”

Issues of identity verification of typical applications over mobile terminal platform
Published 2020-12-01“…Recent studies have shown that attacks against USIM card are increasing,and an attacker can use the cloned USIM card to bypass the identity verification process in some applications and thereby get the unauthorized access.Considering the USIM card being cloned easily even under 5G network,the identity verification process of the popular mobile applications over mobile platform was analyzed.The application behaviors were profiled while users were logging in,resetting password,and performing sensitive operations,thereby the tree model of application authentication was summarized.On this basis,58 popular applications in 7 categories were tested including social communication,healthcare,etc.It found that 29 of them only need SMS verification codes to get authenticated and obtain permissions.To address this issue,two-step authentication was suggested and USIM anti-counterfeiting was applied to assist the authentication process.…”
