For humans, nonvisual biological effects, which can be parameterized by the circadian action factor (CAF), are important for their health and work performance. In this paper, an approach by adjusting electrical currents of three-primary light-emitting diodes (RGB-LEDs) to tune the CAF and color coordinates to be close to those of the standard light with various correlated color temperature (CCT) (2700...
The adaptive phase-only beamforming technique is very important for conventional phased array radar to suppress interference. Similar to conventional phased array radar, for the digital array radar, the adaptive phase-only beamforming technique is also very useful and can be used to enhance the radar power by making full use of transmit module microwave power of each array element. In this paper,...
A biodemulsifier-producing strain of Alcaligenes sp. S-XJ-1, isolated from petroleum-contaminated soil of the Karamay Oilfield, exhibited excellent demulsifying ability. The application of this biodemulsifier significantly improved the quality of separated water compared with the chemical demulsifier, polyether, which clearly indicates that it has potential applications in the crude oil extraction...
