Some teachers believe that although multimedia teaching represents an advanced education concept, totally replacing blackboard writing by computers is against the cognitive regulation and teaching theory.
Summary It is a complicated systematic engineering to building an evaluation system for multimedia teaching, meanwhile, which is an entire new research project of modern education and teaching domain.

Introduction A number of thermo-mechanical processes have emerged recently and often results in superior mechanical properties of advanced materials [1].
However, the change of material states under the thermo-mechanical deformation has rarely been reported, though it is one of the most important areas in materials science and engineering.

Introduction As the technology of renewable energy advanced, new kinds of power source have been used in aviation.
Engineers have been long studied solar cells to use them as propulsion for manned planes or Unmanned Aerial Vehicle (UAV).
So a hybrid of solar cells, fuel cells and rechargeable batteries (lithium batteries) come to the front of engineers.
