Furthermore, all ecological indicators are graded by applying the natural breakpoint classification method, and the indicator values are divided into five grades: extremely low, low, medium, high, and extremely high (Figure 4). Overall, the importance of ecosystem services is mainly distributed in...
GRADED-INDEX MULTIMODE FIBER contains a core in which the refractive index diminishes gradually from the center axis out toward the cladding. The higher refractive index at the center makes the light rays moving down the axis advance more slowly than those near the cladding. Also, rather than ...
In addition, in recent years, the concept and technology of 3D printing have emerged, causing a wave of change in academia and industry, completely revolutionizing various industries and manufacturing. Applying 3D printing technology to fiber manufacturing is considered a milestone in the history of ...
