To provide energy savings and ecological benefits, dimming control is a crucial factor in indoor visible light communication (VLC) system where desired brightness levels can be achieved. General dimming control methods have an adverse effect on communication, e.g., limiting the achievable data rate...

In this paper the dynamic variation of predominating pollutants in Qiandao Lake based on statistical analysis of routine monitoring data from 1989 to 1999 are presented and the origin of those pollutants are discussed. Chemical analysis showed that nitrogen and phosphorus were the main contaminants...

The chlorophyll-a and other water quality indexes were investigated once a month from 1999 to 2000. The spatial and temporal changes in chlorophyll-a concentration in Qiandao Lake were analyzed and the impacts of ecological factors on chlorophyll-a were discussed in the paper. The results showed tha...
