This proposal combines the efforts of research groups from the University of Sao Paulo, State University of Sao Paulo, University of Campinas, Technological Institute of Aeronautics and a number of international collaborators to investigate periodic structures in the context of phononic materials and elastic/acoustic metamaterials. Phononic materials and elastic/acoustic metamaterials can…
This project concerns leak detection in plastic water distribution pipes. It involves two research teams, one from UNESP in Brazil, and one from the Institute of Sound and Vibration Research at the University of Southampton, UK. The focus will be on a fundamental investigation of ground-borne vibration due to a leak in a buried pipe. Measurements will be made in the SABESP in Brazil and a…
This proposal is concerned with the localization of a leak from a buried plastic water pipe using vibration measurements on the surface of the ground. The study will involve the development of an analytical model of a buried pipe, together with an extensive set of measurements made on a test site in São Paulo. The measurements will involve tri-axial accelerometers to determine the importa…
The digital transformation is still little consolidated in Brazilian society. Improvements in performance and differentiation resulting of such transformation have not yet been fully absorbed in companies and in the public administration. In general, solutions required for implementing the digital transformation in cities and in manufacturing processes combine advanced connectivity and au…

Water scarcity, especially in large centers where the reservoirs are at their maximum capacity, as well as the location of generally a few tens of kilometers from external water sources, make sanitation and water distribution companies under great pressure to reduce losses in its distribution systems. In this way, plans for loss management, as well as technologies used in the rapid detect…
This project will design the nonlinear periodic structure and performing experimental tests, aiming at achieving stop-bands at frequencies <100 Hz. The aims of the experiments are to validate the theoretical predictions made from the theoretical models, to investigate the practical issues in realising nonlinear periodic structures, and to determine their practical limitations in terms of …
According to previously works, acoustic correlators have been used more than 30 years to detect and locate leaks from water pipes, since leakage from buried water distribution pipelines is a global problem. Although they work well for metallic pipes there are some issues with plastic pipes because the leak noise which propagates along these pipes are subject to high rates of attenuation, …

This proposal primarily concerns a study into the way in which amplitude distortion of leak noise signals from a buried plastic water pipe, affects the time delay estimate calculated from the correlation of leak noise signals measured either side of the leak. The study will involve the development of an analytical model of a pipe and sensors coupled with a clipping mechanism for the signa…
