In this paper a combination of the multi-agent paradigm and a very well known clustering technique
is used for unsupervised classification of subsoil characteristics working on a collection of ground
penetrating radar ...
[EN] This paper addresses the problem of leakage in water distribution systems through the use of ground penetrating radar (GPR) as a nondestructive method. Laboratory tests are performed to extract features of water leakage ...
In many real-world applications we have at our disposal a limited number of inputs in a theoretical database with full information, and another part of experimental data with incomplete knowledge for some of their features. ...
[EN] Hybrid models have been used in many engineering applications in order to find better solutions and to reduce project costs. In this paper a methodology for the optimal design of collective working shift irrigation ...

[EN] The most important factor in planning and operating water distribution systems is satisfying consumer demand. This means continuously providing users with quality water in adequate volumes at reasonable pressure, thus ...
Knowledge of buried infrastructure is essential for management and decision-making in water utility companies. To pinpoint the benefits of thermography, a case study was conducted, namely, thermal images were taken under ...
Decision making in engineering is becoming increasingly complex due to the large number
of alternatives and multiple conflicting goals. Powerful decision-support expert systems
powered by suitable software are increasingly ...

[EN] This work focuses on the use of easy-to-apply procedures that allow rapid visualization of components of water supply systems (WSSs) by non-highly qualified personnel. We use a methodology that does not alter the ...
The flexibility introduced by evolutionary algorithms (EAs) has allowed the use of virtually arbitrary objective functions and constraints even when evaluations require, as for real-world problems, running complex mathematical ...
Over-exploitation and pollution have been identified as the main problems facing the Silao-Romita aquifer in Guanajuato, Mexico. The objective of this paper is to analyze the current situation, characterized by a clear ...

[EN] Water scarcity should not only be taken into account in its physical sense, but it should also be consideredin teh economic and poor management sense. This scenario provokes the application of intermittent water supply ...
The increasing pressure over water resources has raised the need
to establish procedures to efficiently manage water supply networks (WSN). An
example of such procedures is the sectorization of networks either by ...
This work focuses on the generation of tools to aid inspection and identify buried plastic pipes in water supply systems (WSS). In our study we use ground penetrating system (GPR) images as a non-destructive method of ...

[EN] Currently, intermittent supply is how millions of people get access to water worldwide. Some
researchers suggest that the increasing water scarcity due to climate change and the enlarged demand
by the growing number ...
[EN] Data mining solutions can be applied in combination with evolutionary algorithms to extract relevant information from solution spaces analyzed during optimization processes regarding water distribution system (WDS) ...
Nudelman, Mario Alejandro(Universitat Politècnica de València, 2016-05-04)
[EN] The thesis is aimed at developing a qualified information tool (a dynamic simulation model), that serves as support for local decisions in planning the water and sanitation sector, aimed at sustainability, especially ...
Alonso Guzmán, Carlos Daniel(Universitat Politècnica de València, 2010-07-30)
El abastecimiento de agua está basado en una compleja infraestructura, que simultáneamente se expande y envejece. Cuando las tuberías sufren roturas, es habitual reparar las tuberías cuando los costes de reparación son ...
[EN] The division of a water supply network (WSN) into isolated supply clusters aims at improving the management
of the whole system. This paper deals with the application of spectral clustering to achieve this
aim. A ...
