A simple formula to find the closest consistent matrix to a reciprocal matrix

Benítez López, Julio; Izquierdo Sebastián, Joaquín; Pérez García, Rafael; Ramos Martínez, Eva (Elsevier, 2014-08-01)

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 ...
Application of graph-spectral methods in the vulnerability assessment of water supply networks

Gutiérrez-Pérez, Joanna A.; Herrera Fernández, Antonio Manuel; Pérez García, Rafael; Ramos Martínez, Eva (Elsevier, 2013-04)

[EN] We introduce a methodology based on spectral measurements of graph theory to establish the relative importance of areas in water supply networks (WSNs). To achieve an efficient vulnerability analysis, we have made a ...
Assessing biofilm development in drinking water distribution systems by Machine Learning methods

Ramos Martínez, Eva (Universitat Politècnica de València, 2016-05-02)

[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 ...
Drinking Water Distribution Systems Characteristics on Biofilm Development: A Kernel based Approach

Ramos Martínez, Eva; Herrera Fernández, Antonio Manuel; Izquierdo Sebastián, Joaquín; Pérez García, Rafael (Athens Institute for Education and Research, 2013)

[EN] Biofilm develops in drinking water distribution systems (DWDSs) as layers of microorganisms bound by an organic matrix and attached to pipe walls. The presence of substantial and active attached biomass can lead to ...
Ensemble of naïve Bayesian approaches for the study of biofilm development in drinking water distribution systems

Ramos Martínez, Eva; Herrera Fernández, Antonio Manuel; Izquierdo Sebastián, Joaquín; Pérez García, Rafael (Taylor & Francis (Routledge): STM, Behavioural Science and Public Health Titles, 2014-03)

[EN] Various studies have been performed in relation to the influence that a number of characteristics of drinking water distribution systems (DWDSs) have on biofilm development. Nevertheless, their joint influence, apart ...
Evaluación del desarrollo de biofilms en los sistemas de distribución de agua potable mediante la extracción de conocimiento a través de los datos (Knowledge Discovery in Databases)

Ramos Martínez, Eva (Universitat Politècnica de València, 2013-01-30)

[ES] Uno de los principales objetivos de las empresas encargadas de la gestión de los sistemas de distribución de agua potable (DWDSs, del inglés Drinking Water Distribution Systems) es asegurar una alta calidad ...
Graph constrained label propagation on water supply networks

Herrera Fernández, Antonio Manuel; Ramos Martínez, Eva; Izquierdo Sebastián, Joaquín; Pérez García, Rafael (IOS Press, 2015)

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. ...
Multi-Agent Approach to Biofilm Development in Water Supply Systems

Ramos Martínez, Eva; Herrera Fernández, Antonio Manuel; Izquierdo Sebastián, Joaquín; Pérez García, Rafael (Athens Institute for Education and Research, 2015)

[EN] The presence of regulated quantities of residual disinfectant is a usual feature in water supply systems (WSSs); nevertheless, biofilm formation persists in all of them, representing a paradigm in WSSs management ...
Pre-processing and visualization of biofilm development in drinking water distribution systems

Ramos Martínez, Eva; Herrera Fernández, Antonio Manuel; Izquierdo Sebastián, Joaquín; Pérez García, Rafael (E.W. Publications, 2014)

Biofilm develops in drinking water distribution systems (DWDSs) as complex microorganism communities covered by an extracellular polysaccharide which provides them structure, protection against disinfectants and helps ...
Rehabilitation actions in water supply systems: effects on biofilm susceptibility

Ramos Martínez, Eva; Herrera Fernández, Antonio Manuel; Gutiérrez-Pérez, Joanna A.; Izquierdo Sebastián, Joaquín; Pérez García, Rafael (Elsevier, 2014)

[EN] Biofilm development in water supply systems (WSSs) depends on infrastructure and operational factors, apart from water quality. We have developed a methodology that considers WSSs hydraulic (operation) and physical ...
