A novel technique based on fiber-optic evanescent-wave spectroscopy is proposed for the detection of bacterial activity in human saliva. The sensor determines th e specific concentration of Streptococcus mutans in saliva, which is a major causative factor in dental caries. In this design, one prepares the fiber-optic bacterial sensor by replacing a portion(More)

This paper focuses on the energy compaction properties of five different transforms: DFT, DCT,<lb>SDFT((N+1)/2, 1/2), MDCT and DST. Energy compaction properties of these transforms are compared<lb>experimentally. In addition to sinusoidal signals, sixteen classical and pop music pieces are used for the<lb>experiments. The influence of different window sizes(More)
