This paper presents an automatic control system for welding the root-pass in a seam joining a nozzle perpendicular onto a large diameter pipe. The system is based on the use of a geometry model of the welding seam and on inverse welding process models (i.e. models that map desired weld quality,...

This paper explores methods to study trust. In a variety of settings, answers to survey questions and choices in a trust game are obtained from student sample pools. Some subjects are approached by mail and execute their task at home whereas others participate in classroom experiments. No...
