Investigating the effect of online and offline reputation on the provision of online counseling services

Frontiers of Engineering Management Pages 563-576 doi: 10.1007/s42524-022-0198-0

Abstract: reputation.We collect the data of 141029 physicians from 6173 offline hospitals located in 350 cities in China.Based on the reputation theory and previous studies, we incorporate patients’ feedback as physicians’online reputation and incorporate physicians’ offline professional status as physicians’ offline reputationbehaviors, whereas physicians’ offline reputation significantly and negatively influence their online

Offline motion planning and simulation of two-robot welding coordination

Tie ZHANG, Fan OUYANG

Frontiers of Mechanical Engineering 2012, Volume 7, Issue 1, Pages 81-92 doi: 10.1007/s11465-012-0309-4

Abstract:

This paper focuses on the two-robot welding coordination of complex curve seam which means one robot grasp the workpiece, the other hold the torch, the two robots work on the same workpiece simultaneously. This paper builds the dual-robot coordinate system at the beginning, and three point calibration method of two robots’ relative base coordinate system is presented. After that, the non master/slave scheme is chosen for the motion planning, the non master/slave scheme sets the poses versus time function of the point u on the workpiece, and calculates the two robot end effecter trajectories through the constrained relationship matrix automatically. Moreover, downhand welding is employed which can guarantee the torch and the seam keep in good contact condition all the time during the welding. Finally, a Solidworks-SimMechanics simulation platform is established, and a simulation of curved steel pipe welding is conducted. The results of the simulation illustrate the welding process can meet the requirements of downhand welding, the joint displacement curves are smooth and continuous and no joint velocities are out of working scope.
