[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 ...

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 ...

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 ...

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 ...

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 ...

Este objeto simula el comportamiento de una bolsa de aire atrapada en un extremo ciego de una tubería. En el otro extremo se considera una fuente de energía, representada por la altura constante que proporciona un depósito ...

Las fugas en los sistemas de distribución de agua están provocadas por todos aquellos fallos en las tuberías, accesorios o tanques de almacenamiento que provocan una pérdida de agua. La cantidad de agua que se pierde por ...

[EN] One of the main challenges of drinking water utilities is to ensure high quality supply, in particular, in chemical and microbiological terms. However, biofilms invariably develop in all drinking water distribution ...

En este objeto estudiamos el sencillo atractor de Rayleigh. Su propiedad más interesante es que el atractor es un anillo y todas las órbitas del sistema quedan atrapadas por él. Matemáticamente se trata de un sistema de ...
