This paper present the optimum conditions for direct CO 2 laser cutting of 6-mm-thick polymethylmethacrylate (PMMA) for backlit module applications. The influence of the major processing parameters on the optical transmittance ratio and surface roughness of cut samples material have been discussed.

Digital obesity, or information overload, is a widely recognized yet largely unsolved problem. Lack of metadata-that is, a useful and usable description of what is represented by data-is one of the fundamental obstacles preventing the wider use of computational intelligence techniques in tackling th
This study aims to identify key factors affecting energy-induced CO 2 emission changes from 34 industries in Taiwan, in order to have an integrated understanding of the industrial environmental-economic-energy performance and to provide insights for relevant policy making in Taiwan.
