This paper presents a low cost and holistic approach to the water quality monitoring problem for drinking water distribution systems as well as for consumer sites. Our approach is based on the development of low cost sensor nodes for real time and in-pipe monitoring and assessment of water quality on the fly. The main sensor node consists of several in-pipe electrochemical and optical sensors and...
Bacterial screening is very important in water environmental monitoring, because the presence of dangerous pathogens can seriously endanger human health. Microbial concentration detection is performed by standard plate count technique, which is reliable but is characterized by long response time and is not suitable to be implemented in automatic form. Based on impedance measurements, this paper presents...
Where should we place sensors to quickly detect contamination in drinking water distribution networks? Which blogs should we read to learn about the biggest stories on the Web? Such problems are typically NP-hard in theory and extremely challenging in practice. The authors present algorithms that exploit submodularity to efficiently find provably near-optimal solutions to large complex real-world...
