In this paper, a visible light communication (VLC) in the indoor environment based on MIMO system is investigated and analyzed. An attempt is made to optimize the placement of light emitting diodes (LED) VLC emitter in 4 × 4 MIMO configuration at ceiling and ground floor for the receiver to obtain uniform signal-to-noise ratio (SNR) for the desired(More)
We describe a simultaneous analysis for vanilmandelic and homovanillic acids in urine. An aliquot of a final extract, containing phenylpropriopionic acid as external standard, is dried, an internal standard (resorcinol) is added, and the mixture is silylated and chromatographed. The two compounds are identified from their characteristic retention times and(More)
