Leak detection of water supply networks using error-domain model falsification

2018

Measurement system design for leak detection in hydraulic pressurized networks

This paper compares four sensor placement strategies which differ according to their evaluation criteria (EC). The first involves the minimisation of the expected number of candidate models, and the second is based on maximising joint entropy. The first me ...

An electric network for evaluating monitoring strategies intended for hydraullic pressurized networks

Ian Smith, Gaudenz Moser

This paper presents a study of similarities between electrical and hydraulic pressurized networks. The primary objective is to examine whether or not it is possible to use electrical laboratory networks measuring voltage to study leak-region detection stra ...

Performance assessment of pressurized fluid-distribution networks

Gaudenz Moser

Pressurized fluid-distribution networks are key strategic elements of infrastructure. Drinking water is a precious resource and will become more and more important with the depletion of reserves. With the growth of the human population, challenges related ...

Using electrical resistance networks to enhance performance assessments of water distribution networks

Ian Smith, Gaudenz Moser, Stephanie Ann German

Pressurized fluid-distribution networks are strategic elements of civil infrastructure. In the case of fresh-water distribution networks, where leaks are common and where real performance is unknown, advanced sensor-based diagnostic methodologies have the ...

Performance comparison of reduced models for leak detection in water distribution networks

Ian Smith, Gaudenz Moser, Stephanie Ann German

This paper presents a methodology for comparing the performance of model-reduction strategies to be used with a diagnostic methodology for leak detection in water distribution networks. The goal is to find reduction strategies that are suitable for error-d ...

Detecting leak regions through model falsification

Ian Smith, Gaudenz Moser

Pressurized fluid-distribution networks are strategic elements of infrastructure. In the case of fresh-water distribution networks, advanced sensor-based diagnostic methodologies have the potential to provide enhanced management support. Since a significan ...

Experimental investigation into segregating granular flows down chutes

Christophe Ancey, Nicolas Andreini, Gaël Epely Chauvin, Sébastien Wiederseiner, Gaudenz Moser

We experimentally investigated how a binary granular mixture made up of spherical glass beads size ratio of 2 behaved when flowing down a chute. Initially, the mixture was normally graded, with all the small particles on top of the coarse grains. Segregati ...
