This paper presents some aspects of the time propagation of underground water leakage in controlled laboratory conditions using a drilled polyvinyl chloride (PVC) pipe and interpreting ground penetrating radar (GPR) images. ...
[EN] In this paper, a ground penetrating radar (GPR) is used as a non-destructive
method to assess the buried elements of water supply systems (WSSs). The aim
is the detection of various pipe materials (such as plastic ...

[Otros] Leak detection and isolation (LDI) is a problem of interest for water management companies
and their technical staff. Main reasons for this are that early detection of leakages can reduce
dramatically (1) water ...
A novel methodology to sectorize water supply networks (WSNs) depending on a main transmission
line is presented in this paper. The methodology is based on concepts derived from the social
network theory and graph theory ...
[EN] Data processing techniques for Ground Penetrating Radar (GPR) image mining provide essential information to optimize maintenance management of Water Supply Systems (WSSs). These techniques aim to elaborate on radargrams ...

Selecting the most appropriate heuristic for solving a specific problem is not easy, for many reasons. This article focuses on one of these reasons: traditionally, the solution search process has operated in a given manner ...
[EN] The core idea behind sectorization of water supply networks (WSNs) is to establish areas partially isolated from the rest of the network to improve operational control. Besides the benefits associated to sectorization, ...
Achieving consistency in pair-wise comparisons between decision elements given by experts or stakeholders is of paramount importance in decision-making based on the AHP methodology. Several alternatives to improve consistency ...
One of the important issues related with all types of data analysis, either statistical data analysis, machine learning,
data mining, data science or whatever form of data-driven modeling, is data quality. The more complex ...
Matrices used in the analytic hierarchy process (AHP) compile expert knowledge as pair-wise comparisons among various criteria and alternatives in decision-making problems. Many items are usually considered in the same ...
