The interest in the exploitation of wireless sensor networks in dissipative media (other than the free space) is nowadays growing in importance, thanks to the identification of ever newer fields of applications. This paper introduces an efficient design methodology for an easy definition of the characteristics of mobile sensors inserted in pipes filled with fluids. The proposed procedure takes into...
High-voltage direct current electrical method can effectively detect the integrity of landfill liner. The total loop current plays a decisive role in detecting result. Direct current circuit model for landfill leakage detection of high-voltage direct current method is established in this paper. The circuit is made up of four parts: grounding resistance of the power electrode in the medium above the...
In view of the problems of using traditional monitoring method for SF6 gas leakage in electrical equipments, according to the photoacoustic spectrometry technology, the photoacoustic spectrometry experiment system is designed for detecting SF6 gas concentration. The generation of photoacoustic spectrum is presented, the photoacoustic technique is used to survey the photoacoustic characteristic of...
