Vertical handoff is one of the most challenging issues in heterogeneous network environments. The existing vertical handoff decision methods have some disadvantages such as unfeasibility, ping-pong effects and inefficient utilization of wireless network resources. An application-oriented cooperative vertical handoff decision method for multi-interface mobile terminals is proposed in this paper. It...
The experiment of capillary electrophoresis (CE) is put up with the laser induced fluorescence detection (LIFD) system made by ourselves. The model same as the actual system is set up in the software of optical simulation. In order to heighten the fluorescence signals intensity, increase the light spot which illuminate in the detection window of capillary instead of the traditional way: make the light...
Capillary electrophoresis and microchip capillary electrophoresis based on laser induced fluorescence detection (CE-LIFD) played an important role in biology and analytical chemistry for separation and quantitative research of biological samples. This paper presented an analysis on the noise of LIF detection brought by scattering from polymer used as sieving matrix. The theory of laser scattering...
