MockUpDefinition of MOCK-UP: In common usage, a mockup is a scale model of a structure or device, usually used

for teaching, demonstration, testing a design, etc. - WIKIPEDIA

New Positioning for the Baffle Analysis

• Because Baffles is over the buffer region,we couldn’t know how it run.

Baffle 이 Buffer 를 넘어버려 이들의 Effect 를 볼 수 없음
