The crystal structure of a material plays an important role in determining its electronic properties. Changing from one crystal structure to another involves a phase transition that is usually controlled by a state variable such as temperature or pressure. In the case of trilayer graphene, there are two common stacking configurations (Bernal and rhombohedral) that exhibit very different electro...
A microcomputer-based optimal control system for electric wheelchairs is presented. As the weight of a wheelchair is generally small compared to that of a user, the user's actual weight can have a tremendous impact on the dynamics of the wheelchair. The velocity feedback controller presented here was designed to give an optimal response for all users by incorporating a measure of the individual...

Large ships adopt a central fresh water-cooling system that indirectly cools waste heat with seawater to discharge the ship′s out of ship. Such is essential for future electric powered ships. Since 2010, shipping companies have attempted save energy by applying variable-speed cooling pumps FW system, but due minimum-required pressure pump, they applied existing 3-way valve alongside. However, s...
