Robot Programming by Demonstration (PbD) examines methods by which a robot learns new skills through human guidance. Also referred to as learning by imitation, tutelage or apprenticeship learning, PbD takes inspiration from the way humans learn new skills by imitation, thereby developing methods by which new skills can be transmitted to a robot.

Solidication is one of the oldest processes for producing complex shapes for applications ranging from art to industry, and it remains as one of the most important commercial processes for many materials. Since the 1980's, numerous fundamental developments in the understanding of solidication processes and microstructure formation have come from both analytical theories and the application of computational techniques using commonly available powerful computers.
