Humans are error-prone in the presence of multiple similar tasks. While Human-Robot Collaboration (HRC) brings the advantage of combining the superiority of both humans and robots in their respective talents, it also requires the robot to communicate the task goal clearly to the human collaborator. We formalize such problems in interactive assembly tasks with hidden goal Markov decision processes...
The flow behavior of polymer flooding solution can not only be described simply with shear flow field, but also with convergent and extensional flow field. The extensional viscosity of polymer solutions used in polymer flooding in Daqing Oilfield was investigated with CaBER1 extensional rheometer, and the results showed that the extensional viscosity of which is much higher than shear viscosity with...
